Le droit constitutionnel aux communications et aux services publics fédéraux dans la langue officielle de son choix
Authors: Rouselle Serge
Published: January 2025

Selon les enseignements de la Cour suprême du Canada, le droit d’employer le français ou l’anglais prévu au paragraphe 20(1) de la Charte pour communiquer avec les institutions fédérales et pour en recevoir les services doit s’interpréter de façon large et libérale en fonction de son objet culturel et réparateur afin de modifier le statu quo et de favoriser l’égalité réelle en la matière. Dans cette optique, une analyse de la jurisprudence pertinente permet de mieux définir le contenu de ce droit, mais également d’en apprécier la portée et le plein potentiel. À cette fin, cette analyse nous révèle que ce droit constitutionnel s’étend le long d’un spectre allant de services identiques à des services différents pour chacune des communautés de langue officielle, et ce, afin de réaliser pleinement l’égalité linguistique réelle.
Access to Administrative Justice as an Administrative Law Value: Designing an Inclusive and Accessible Administrative Justice System
Authors: Jacobs Laverne
Published: January 2025

The constantly developing norm of access to justice is moving to occupy a central place in the administrative justice system,  prompting a need to rethink the values that should serve to animate the system. This article offers a framework for the administrative justice system in Canada, one that firmly and explicitly entrenches the value of access to administrative justice within it. It reflects on the requirements to achieve access for a significant population of its users – namely, equality-deserving communities. The author looks at the historical reasons why access to justice has been a concern for equality-deserving communities, and introduces the concept of social equity from the discipline of public administration as a tool to assist in addressing some of the structural and systemic access-to-administrative-justice challenges experienced. The author rearticulates the foundational values of administrative law in Canada to incorporate access to administrative justice as a distinct value, one that engages with access-to-justice barriers relating to structural and systemic inequality. In doing so, she details five core principles that underpin the new value of access to administrative justice and cites examples of recent tribunal reform projects in Canada that illustrate promising innovations in that direction. Finally, the author describes briefly the ways in which institutional design and tribunal culture can contribute to enhancing the value of access to administrative justice within the broad, on-the-ground context of different administrative actors. Overall, this article presents an analysis of the dynamic interaction between marginalized populations and the administrative state in order to move forward judicial and other contemporary discussions about access to administrative justice and how it should be defined.
Des-q: a quantum algorithm to provably speedup retraining of decision trees
Authors: Kumar Niraj , Yalovetzky Romina , Li Changhao , Minssen Pierre , Pistoia Marco
Published: January 2025

Decision trees are widely adopted machine learning models due to their simplicity and explainability. However, as training data size grows, standard methods become increasingly slow, scaling polynomially with the number of training examples. In this work, we introduce Des-q, a novel quantum algorithm to construct and retrain decision trees for regression and binary classification tasks. Assuming the data stream produces small, periodic increments of new training examples, Des-q significantly reduces the tree retraining time. Des-q achieves a logarithmic complexity in the combined total number of old and new examples, even accounting for the time needed to load the new samples into quantum-accessible memory. Our approach to grow the tree from any given node involves performing piecewise linear splits to generate multiple hyperplanes, thus partitioning the input feature space into distinct regions. To determine the suitable anchor points for these splits, we develop an efficient quantum-supervised clustering method, building upon the q-means algorithm introduced by Kerenidis et al. We benchmark the simulated version of Des-q against the state-of-the-art classical methods on multiple data sets and observe that our algorithm exhibits similar performance to the state-of-the-art decision trees while significantly speeding up the periodic tree retraining.
Contemporary Stoicism and Civic Values
Authors:   Latvijas Nacionālā aizsardzības akadēmija, Latvijas Universitātes filozofijas doktorantūra, Leitlande Gita
Published: January 2025

The doctoral thesis’s theme, “Contemporary Stoicism and Civic Values”, highlights the potential
of an interface between the philosophy of Stoicism and the functioning of the country by strengthening
civic values. The aim of the thesis is to offer a vision of how the philosophy of Stoicism, in its
contemporary interpretation, can be applied to address topical issues at the national level – strengthening
civic values in Latvia. The research (1) identifies the current country’s needs and challenges regarding
strengthening civic values; (2) examines the formation and variations of Stoic philosophy and ethics
over time, including the most significant criticism of Stoicism, from the origins of the teaching (ancient
Stoicism) to the present day (contemporary Stoicism); (3) formulates the interpretation of Stoic
philosophy and ethics used in the thesis: what is the ultimate goal of the teaching and the main
components of the strategy to achieve it. Based on this understanding of contemporary Stoicism and the
identified issues regarding civic values, the thesis (4) explores the potential and limitations of applying
contemporary Stoicism to strengthening two core civic values – autonomy and solidarity – in Latvia.
However, Stoicism as a philosophical teaching offers a more fundamental transformation and impact on
the person than just the cultivation of these two civic values. Stoicism affects the whole personality
(character), a person’s worldview and way of thinking, as well as the understanding of the country’s role
in a person’s beliefs and actions. These aspects reinforce the effectiveness of Stoicism and, thus, its
usefulness to the country in the context of strengthening civic values. The final chapter of the thesis
(5) analyzes three case studies that illustrate the applicability of Stoicism in specific areas: regarding
care for nature, military service, and character education in schools.
LEGAL STATUS ON PURCHASE TRANSACTIONS BY MINORS IN BANDA CITY
Authors: Mufid  , Nahara Eriyanti
Published: January 2025

The phenomenon of minors involved in buying and selling transactions in Banda Aceh City is a complex issue influenced by economic, educational, socio-cultural factors, as well as weaknesses in regulation and law enforcement. This research aims to analyze the factors causing this phenomenon and view it from the perspective of Islamic law and Law No. 13 of 2003 concerning Manpower. In Islamic law, a child who has not reached the age of maturity is considered not qualified to engage in valid transactions without the supervision of a guardian. Meanwhile, labor regulations in Indonesia prohibit minors from working except under certain conditions. This study uses a qualitative approach with a descriptive-analytical research type. Data were obtained through observation, interviews, and documentation methods, supported by secondary data from the literature. The research results show that poverty, low parental education, social norms, and the impact of the COVID-19 pandemic are dominant factors driving children to work in the informal sector. In Islamic law, small transactions conducted by children are considered valid if they meet the principles of justice and basic needs without exploitation. However, high-value transactions require guardian supervision to ensure validity. This research recommends the need for strict supervision, community education, and consistent law enforcement to protect children's rights in accordance with Islamic law and legislation.
REVIEW OF THE CONCEPT OF JU'ALAH ON INCOME EARNED FROM LIVE STREAMING ON SOCIAL MEDIA
Authors: AL HILAL AKBAR  , Nurdin Bakri  , Yuhasnibar
Published: January 2025

This research examines the concept of ju'alah in Islam and its application to income earned from live streaming activities on social media, focusing on the Tiktok application. Ju'alah is one of the contracts in fiqh muamalah, which is an agreement that promises certain rewards for parties who perform certain tasks. In the context of live streaming, the income received by streamers generally comes from audience gifts in the form of stickers which are then converted into money. The research method used in this study is a mixed methods research method that combines normative and empirical methods included in qualitative research. This research is descriptive in nature where most of the data used comes from interviews, observations in the form of sentences or narratives. The results of this study indicate that gifting is in accordance with the ju'alah contract if it is given after the implementation of the audience request. If there is fraud such as a gift has been given but the request has not been carried out in this case there is no positive legal action because there is no written agreement, while in Islam this is considered fraud so that the money earned by the creator is considered not halal.

This paper formulates and examines the approach of integrating PSO into the tune of DNNs for boosting the predictive capability in renewable energy systems and green building designs. The PSO method was then employed to select Key features such as; Solar Irradiance, Ambient Temperature, Panel Efficiency and Energy Output. The PSO-based feature selection resulted in significant enhancements across a set of four metrics, there was an improvement in accuracy from a previous 0.82 to 0.87, precision from the previous 0.78 to 0.83, as well as recall from the previous 0.76 to 0.81, and the F1-Score from a previous 0.77 to the current score of 0.82. Moreover, the RMSE values reduced from 0.27 to 0.23, and the AUC values enriched from 0.74 to 0.85. Thus, the results of the current study support PSO’s role in improving feature selection, which, in return, improves the predictive models of energy management. The paper presented emphasizes the possibility of the use of enhanced optimization algorithms in enhancing the best performing, less resource-intensive, and environmentally friendly energy solutions in architecture.
Effect of curing temperature on the soil physical and mechanical properties on clay shale geopolymer fly ash stabilization
Authors: Hartono Edi , Diana Willis , Muntohar Agus Setyo , Azhar Muhammad , Indriani Lia
Published: January 2025

Clay shale is an easily degraded mudrock when exposed to weathering. The reduced strength due to degradation can be mitigated through soil stabilization. In recent years, soil stabilization using geopolymers has become one of the latest popular methods due to its economic benefits and lower carbon footprint. A widely used cementitious material for this method is fly ash-based geopolymer. The relationship between curing temperatures and the performance of clay shale stabilized with fly ash-based geopolymer has yet to be studied for the purpose of identifying a more effective stabilization method. In this study, clay shale was stabilized using geopolymer. The geopolymer was made of fly ash and an activator. Sodium hydroxide (NaOH) and sodium silicate (Na2SiO3) as activators. The activator is diluted with water to create a 12 M mixture. Before the unconfined compressive strength test, the specimens were subjected to various curing temperatures from 26oC to 60oC. The test result shows that, in general, higher curing temperatures increased the dry density from 1.66 g/cm3 to 1.84 g/cm3. Meanwhile, the unconfined compressive strength multiplies about 3.5 times. Furthermore, the moisture content decreased after the curing process from 19% to 2.5%. This led to the specimen volume experiencing decrement due to the shrinkage during the curing period. The volume reduces from 67.7 cm3 to 63.5 cm3. In general, temperature plays a significant role in enhancing the strength of clay shale stabilized using fly ash-based geopolymer.

Authors: Fireza Doni , Sabil Azmal , Utaberta Nangkula
Published: January 2025

Contemporary mosque architecture, as part of postmodern architecture, is an interesting focus of discussion, which has dimension of subjective meanings represented or symbolized in the architectural design. Thus, this can be viewed as a medium of communication between architects and the public, or in the context of mosque architecture, as a medium for conveying Islamic teachings to the ummah. To understand how design symbolism communicates ideas in architecture, selected publications on contemporary mosque architecture were reviewed within the postmodern architectural paradigm. This study aims to critically develop new ideas and perspectives from contemporary mosque architecture as a communication medium of religious values and teachings. Using integrative literature review as methodology, the result is the construction of new ideas and perspectives regarding the relationship among aspects in the paradigm of postmodernism developed in mosque architectural history.

Authors: Setyaningrum Hanny , Sriwana Iphov Kumala , Mufidah Ilma
Published: January 2025

The medical device industry company experienced the problem of prolonged accumulation of finished goods in the warehouse, causing one of the safety box items to be defective and damaged. Therefore, this study aims to plan demand forecasting and design inventory policies that consider repair items caused during the buildup of finished goods in the warehouse to minimize total inventory costs using ANN and Continuous Review (s,Q) methods. Demand forecasting is carried out for the next 20 months, from May 2023 to December 2024, using the ANN model with a total forecasting of 17936 units of inner items and 3370 units of outer items. After that, the inventory policy calculation uses the continuous review (s,Q) method. The calculation results show a decrease in the total inventory cost on inner items by 83% and outer items by 79%. After demand forecasting, there was also a decrease in the total initial inventory cost of inner items by 81% and outer items by 80%. This research develops an inventory optimization model that considers repair items due to the accumulation of goods in the warehouse by integrating holding cost, ordering cost, and repair cost variables to develop inventory policies to be more effective and efficient and to utilize damaged products for repair and resale. The limitation of this research is that it only gets demand forecasting results for the next 20 months because the company only started operating in September 2021 and limited data access. It is hoped that future researchers can plan and design an inventory policy strategy with demand forecasting for the next 10 years, focusing on repair items caused by the accumulation of finished goods in the warehouse.

Published: January 2025

This study presents an enhanced recommender system tailored for e-commerce platforms specializing in cosmetic products. Traditional recommender systems often need help providing accurate and personalized recommendations due to the complexity and subjectivity inherent in cosmetic preferences. In e-commerce, personalized product recommendations are crucial to improving user engagement and driving sales. This paper presents an innovative approach to enhance recommendation systems by leveraging neural network collaborative filtering techniques for the cosmetic product domain. The proposed method integrates neural networks into collaborative filtering, namely neural network collaborative filtering with improved preprocessing step. To validate the effectiveness of our proposed system, extensive experiments were conducted using real-world e-commerce cosmetic datasets "eCommerce Event History in Cosmetics Shop".   Additionally, we evaluate the system's performance using historical e-commerce event data in cosmetics stores, demonstrating the system's effectiveness with mean reciprocal ratings (MRR) and normalized discount cumulative gain (NDCG). Evaluation Metrics of MRR and NDCG in this study got 0.56 and 0.60, respectively, with a split of the data: 70% train data, 15% validation data, and 15% test data. This study obtained better evaluation metrics than the previous study, which had an MRR of 0.31 and NDGC of 0.32. Furthermore, this model exhibits robustness against data sparsity and cold-start problems commonly encountered in e-commerce platforms. This research advances knowledge of recommendation systems and paves the way for more personalized and efficient online shopping experiences.

Published: January 2025

Many problems are found in water treatment and distribution in water operations. Those problems range from low to critical risk. All critical risks must be addressed immediately. The Failure Mode and Effects Analysis (FMEA) prioritizes problems based on Occurrence, Severity, and Detection values to identify critical risks. However, this method is also having problems. With the same risk priority number (RPN) calculation, FMEA would be a ranking problem with the same RPN value; hence, we have a priority problem that is not critical but based on the highest value. To solve this problem, we propose additional methods, such as the ANFIS, to give weight based on risk level classification. From the results of data processing carried out by the ANFIS method, it is proven that it can perform re-ranking, for example, in the L2, R5, S8, and U3 code, which has an FMEA RPN value of 12. However, in FMEA-ANFIS, the RPN value becomes L2 2.05, R5 1.52, S8 1.32, and U3 2.52. Furthermore, with these results, it can be concluded that the ANFIS method can enhance the FMEA model in water operations.
Innovative bio-inspired solar cells using fly ash-based dye-sensitized cells with fruit extract enhancements and Averrhoa bilimbi electrolyte
Authors: Utami Retyo Wizi Nafa , Dewi Tresna , Indrayani Indrayani
Published: January 2025

This study responds to the urgent need for renewable energy in Indonesia, driven by climate change and the energy crisis, by developing dye-sensitized solar cells (DSSCs) using locally sourced, eco-friendly materials. Traditional silicon-based photovoltaic cells, which have plateaued at 27% efficiency, are costly and environmentally unfriendly, leading to the demand for alternatives like DSSCs, which offer lower production costs, flexibility, and effective performance in diffuse light. The research focuses on designing DSSCs with Fe and Mg extracted from fly ash as counter electrodes, dragon fruit peel as a natural dye sensitizer, and Averrhoa bilimbi as an electrolyte booster. UV-Vis spectroscopy demonstrated that dragon fruit dye absorbs light effectively in the 360-700 nm range, peaking at 550 nm, making it an ideal sensitizer for wide-band gap semiconductors. Voltage output tests showed that Fe-doped DSSCs consistently outperformed Mg-doped ones, with Fe-based cells generating a maximum voltage of 413 mV compared to 163 mV for Mg-based cells. Long-term testing over three months further demonstrated Fe-doped cells' superior performance, peaking at 454.6 mV, while Mg-doped cells reached 261.96 mV. These results highlight Fe's effectiveness as a doping material, improving DSSC efficiency and supporting the use of natural dyes and sustainable materials. The study aligns with prior research on the critical role of material properties and solar irradiance in DSSC performance, demonstrating the potential of using fly ash and natural dyes for efficient solar energy solutions in South Sumatra. Future research will focus on optimizing material composition for enhanced performance.

People with visual impairments often face difficulties in determining the authenticity of paper money, which is a crucial skill to avoid fraud. The limitations of traditional methods, like blind codes for visually impaired people, require a more advanced and efficient solution. Previous methods of currency detection using Convolutional Neural Network (CNN) techniques, including the VGG-19 architecture, have often encountered challenges, particularly the long training times required. Therefore, we propose using transfer learning techniques and modifying the top layers of the VGG-19 model, known as fully connected layers, within a mobile application with audio feedback built using Android Studio. These modifications involve substituting the three fully connected layers with dense and flattened layers. We also implemented hyperparameter tuning, including adjusting the batch sizes and setting the number of epochs. The datasets used Indonesian Rupiah paper currency from the 2022 emission year, specifically Rp 50,000 and Rp 100,000 denominations. The best transfer learning VGG-19 model achieved a batch size of 32 and an epoch of 50, resulting in a high accuracy of 88%. Response speed testing with performance profiling on Android Studio showed an overall average response time of 458 ms. The main advantage of using transfer learning with the VGG-19 model is that it significantly reduces training time while still achieving high accuracy, differentiating this work from previous studies that relied on training from scratch, which is more time-consuming and resource-intensive. Therefore, this mobile app can be categorized as having a fast response time.

The relationship between good governance and organizational performance through the mediating role of employee satisfaction
Authors: Phuangsuwan Penpim , Siripipatthanakul Supaprawat , Praesri Siriporn , Rakpathum Watthanasakon
Published: January 2025

The 13th Plan of Thailand (2023–2027) states that good governance is a non-economic factor affecting economic development (Office of the National Economic and Social Development Board & Office of the Prime Minister, 2023; Solaymani & Montes, 2024). This study examines the influence of good governance on organizational performance through mediation of employee satisfaction in business companies. Good governance comprises four factors: social development, economic management, employee participation, and work orientation. Self-administered questionnaires were distributed to respondents working at business companies in Thailand through a convenience sampling online survey of 395 respondents. The Statistical Package for the Social Sciences (SPSS) v. 29 was employed for descriptive analysis, and ADANCO v. 2.3.2 was used to test the hypotheses. The partial least squares structural equation modeling (PLS-SEM) shows that employee satisfaction mediates good governance and organizational performance through social development and economic management (but not employee participation and working orientation). To boost employee satisfaction and performance, businesses should adopt good governance. Business companies should prioritize economic management, social development, employee participation, and working orientation for effective governance. Company policies that promote openness could help economic management. Lifelong learning and transparency in human resource skill development could also boost social growth for the organization. Qualitative interviews provide more insight into additional research.

Authors: Park Jae Hyun , Choi Tae-Hyun , Jang Moon-Jung , Kim So-Yeon , Lee Nam-Ki
Published: January 2025

Objectives

To evaluate the treatment effects of the modified miniscrew-assisted rapid palatal expander (MARPE) and rapid palatal expander (RPE) with distalizers in patients with Class II malocclusion and maxillary crowding.

Materials and Methods

The sample comprised 28 skeletal Class I adolescents with dental Class II malocclusion and maxillary crowding of >4 mm who received nonextraction treatment. Fourteen patients were treated with a modified MARPE with distalizer (MMD), while another 14 patients were treated with a modified RPE with distalizer (MRD). Lateral cephalograms and study casts were taken at pretreatment (T1) and after expansion, distalization, and at the initiation of alignment (T2). Twenty-nine variables were compared using a Bonferroni-adjusted independent t-test and a Mann-Whitney U-test.

Results

From T1 to T2, the maxillary first molars in the MMD group exhibited distalization of 3.0 mm and 2.4 mm at the crown and root (P < .001) compared with 2.1 mm and 1.4 mm in the MRD group. However, no significant difference was found in distalization between the two groups. The first molars in the MRD group showed a significantly greater distal tipping of 2.8° than in the MMD group (P < .001).

Conclusions

Although both groups showed maxillary molar distalization, the MMD group had no distal molar tipping, while there was significant molar tipping in the MRD group. It can be useful to plan nonextraction treatment with maxillary expansion and molar distalization in patients with Class II malocclusion and a narrow maxillary arch.

Authors: Arıcan Galip Orkun
Published: January 2025

This study presents a dual-band bandpass filter design that implements microstrip to substrate integrated waveguide (SIW) transition to decrease radiation losses. The proposed filter is designed with using four complementary split ring resonators (CSRR) to minimize its size and to gain double negative property. A bowtie shaped slot is etched inside CSRR to have a second resonance at the spectrum. After the simulation results are performed the designed filter is fabricated on a Rogers RT5880 dielectric substrate and the experimental results are compared with the simulation results. The proposed filter has center frequencies at 6.57 and 12.55 GHz with fractional bandwidth (FBW) of 22.05% and 26.29%, respectively. Moreover, the presented filter offers the best bandwidth-to-size result with the size of 0.327λg×0.352λg (where λg is the wavelength at the first passband’s center frequency).
An Acta Orthopaedica educational article: Treatment of pediatric spondylolysis and spondylolisthesis
Authors: Helenius Ilkka , Virkki Ella , Toomela Taavi , Studer Daniel , Gehrchen Martin , Ahonen Matti
Published: January 2025

Spondylolysis is defined as a defect or elongation in the pars interarticularis of the lumbar spine, either unilateral or bilateral. Growing children with bilateral spondylolysis may develop spondylolisthesis, i.e., forward slipping of the affected vertebra. The etiology of spondylolysis is regarded as a stress fracture due to repetitive loading associated with a genetic predisposition. Lumbar magnetic resonance imaging (MRI) shows an increased signal intensity before an actual fracture line develops. In low grade spondylolisthesis, two-thirds of children with acute pediatric spondylolysis will undergo bony union with early activity restriction. Health-related quality of life is improved in patients achieving bony union as compared with patients having non-union, of which one-fourth will additionally develop spondylolisthesis. In patients with high-grade spondylolisthesis, defined as a more than 50% forward slippage of the affected vertebra, spinal fusion is recommended to prevent further progression.

Published: January 2025

Background and purpose: The optimal approach to the hip joint in patients with displaced femoral neck fractures (dFNF) receiving a total hip arthroplasty (THA) remains controversial. We compared the direct lateral approach (DLA) with the direct anterior approach (DAA) primarily on Timed Up and Go (TUG), and secondarily on the Forgotten Joint Score (FJS), the Oxford Hip Score (OHS), EQ5D-5L, and the EQ5D-VAS.Methods: Between 2018 and 2023, we conducted a randomized controlled trial including elderly patients with dFNFs treated with THA. The primary outcome was the difference in TUG at 6 weeks postoperatively. Key secondary outcomes were TUG at 2, 12, and at 52 weeks postoperatively, and FJS, OHS, EQ5D-5L, and EQ5D-VAS at 2, 6, 12, and at 52 weeks postoperatively.Results: 130 patients with a mean age of 78.6 (standard deviation 1.2) were allocated to DAA (n = 64) or DLA (n = 66). There was no statistically significant difference in TUG times at 6 weeks postoperatively between the DAA and the DLA, 16.0 s (95% confidence interval [CI] 13.2–18.7) vs 17.8 s (CI 15.1–20.4), estimated mean difference –1.8 s (CI –5.7 to 2.0). However, patients who underwent DAA had a significantly higher FJS at 2, 6, and 12 weeks.Conclusion: Among elderly patients with dFNF we found no difference between DAA or DLA regarding crude mobility as demonstrated with the TUG test, but patients treated with DAA showed better outcomes in the FJS in the early post-fracture period though not at 52 weeks.
Fra kurs til partnerskap? Dekomp som mulig samarbeidsarena – et lærerutdanningsperspektiv
Authors: Rubilar Kristine Haugen
Published: January 2025

Flere har framhevet at partnerskapet mellom lærerutdanningen og grunnskolen må styrkes. Desentralisert ordning for kompetanseutvikling (dekomp) har et potensial til å bli et viktig rom for samarbeid og en arena for læring og utvikling av nye forbindelser mellom disse to institusjonene. Det mangler imidlertid kunnskap om hvordan ulike aktører i lærerutdanningen opplever dette samarbeidet. Med utgangspunkt i intervjuer med ti informanter fra én lærerutdanning belyser artikkelen hvordan dekomp har brakt institusjonene nærmere hverandre ved å gå bort fra at lærerutdannere holder kurs for lærere, til å vektlegge refleksive møter mellom teori og praksis. Analysen viser at vi er et stykke unna å etablere deltakende fellesskap der man samskaper som partnere. Lærerutdannerne peker på at det er avstand til skolene, og usikkerhet rundt egen kompetanse og rolle. Å skape gjensidig tillit og å bygge relasjoner krever tid og tålmodig arbeid, men er grunnleggende for at nye måter å jobbe sammen på får vokse fram. 
ENGLISH ABSTRACT
From giving courses to developing partnership? Dekomp as a potential arena for collaboration – a teacher training perspective
The need to strengthen partnerships between higher education and schools is emphasised in several contexts. The decentralised programme of competence development (dekomp) has the potential to become an important collaboration space and an arena for learning and creating new connections between the two institutions. How different agents in teacher training experience this collaboration has been explored to a lesser degree. Based on interviews with ten informants from one teacher training programme, this article illustrates how dekomp has brought the institutions closer together by shifting the focus from teacher training specialists holding courses for teachers, to the reflexive interaction between theory and practice. At the same time, the analysis shows that we are a long way from the establishment of participatory communities where we are able to co-create as partners. Teacher training specialists point to a gap between teacher training and schools, and experience uncertainty about their own competence and role. Creating mutual trust and building relationships not only requires time and patience but is fundamental for the development of new ways of working together.

Pulau Lombok adalah sebuah pulau di kepulauan Sunda Kecil atau Nusa Tenggara yang terpisahkan oleh Selat Lombok dari Bali di sebelah barat dan Selat Alas di sebelah timur dari Sumbawa. Pulau ini kurang lebih berbentuk bulat dengan semacam "ekor" di sisi barat daya yang panjangnya kurang lebih 70 km. Luas pulau ini mencapai 5.435 km² menempatkannya pada peringkat 108 dari daftar pulau berdasarkan luasnya di dunia. Pulau Lombok menjadi salah satu destinasi wisata di Indonesia yang cukup terkenal di dunia. Pesona yang menawan dari Lombok seperti pantai dan gunung menjadi ciri khas tersendiri dari pulau Lombok. Bahkan sering kali Pulau Lombok dibilang pulau kedua dari pulau Bali. Tidak bisa dielakkan lagi bila kebutuhan pariwisata bisa menjadi semakin menarik perhatian banyak orang Sektor Pariwisata 95 % masyarakat yang berada di Desa Pemenang Barat menggantungkan diri bekerja di 3 Gili yaitu Gili Trawangan, Air dan Meno. Namun dengan adanya kondisi pandemi Covid-19 saat ini menyebabkan ekonomi lumpuh dan menyebabkan Masyarakat Desa Pemenang Barat beralih profesi menjadi tukang kebun untuk mencukupi kebutuhan sehari-hari. Pemenang Barat yang memiliki potensi yang cukup besar dan strategis karena view atau pemandangannya langsung tertuju kepada 3 gili dan Gunung Agung sehingga kami bekerja sama dengan Pokdarwis Pemenang Barat untuk membuat konsep spot foto sunset hill dengan beserta camping ground. Tujuan dari program kami yaitu meningkatkan dan mengembangkan Desa Wisata Sumbur Suma di Desa Pemenang Barat sebagai pendapatan bagi masyarakat di era pandemi ini. Diharapkan melalui program pengabdian ini dapat meningkatkan kondisi perekonomian masyarakat melalui Desa Wisata Sumbur Suma Teluk Kombal Desa Pemenang Barat Kabupaten Lombok Utara. Sikap masyarakat yang sangat menghargai, membimbing dan sangat membantu dalam kegiatan sangatlah memotivasi kami untuk melaksanakan setiap program KKN MAs dengan sebaik-baiknya. Sebagai hasilnya, semua program KKN MAs dapat berjalan dengan lancar sesuai rencana.

The phenomenon of tidal flood in the northern coastal areas of Java Island, which frequently occurs nowadays, is likely a consequence of rising sea levels due to global warming. The phenomena of urbanization and industrialization in the northern coastal areas of Tegal Regency can also contribute to the increase in built-up areas, adding pressure to the land surface in the coastal regions. Additionally, intensive groundwater extraction is occurring in densely populated coastal areas due to various activities. The high concentration of industrial and residential zones along the coast of Tegal Regency, coupled with extensive land subsidence due to intensive water abstraction, can lead to subsidence phenomena. The combination of rising sea levels and land subsidence can exacerbate the impact of tidal floods, making them more widespread and severe. The coastal areas of Tegal Regency are among those frequently affected by tidal floods. Analyzing tidal floods is crucial for integrated coastal management to support regional development. Assistance in developing a tidal flood mitigation plan in this coastal area is instrumental for local governments in planning and spatial arrangement in Tegal Regency. Support has been provided to local authorities, including BAPPEDA and Litbang Tegal Regency, to plan spatial arrangements in the northern coastal areas of Tegal Regency. The assistance activities include drone photography in the most severely affected areas, such as Kramat District. Additionally, the team periodically measures elevation to help local governments identify the potential occurrence of land subsidence. Furthermore, a Forum Group Discussion has been conducted to formulate the most suitable mitigation plan considering the conditions in Tegal Regency.

The management of hazardous and toxic waste (B3) and household pharmaceutical waste is a critical issue due to its adverse effects on human health and the environment. B3 waste, such as used batteries, light bulbs, spent oil, and aerosol cans, poses a significant risk of contaminating soil, water, and air if not properly managed. Pharmaceutical waste, including expired or damaged medications, also has the potential to harm public health. Improper disposal can lead to pollution, causing acute health problems such as neurological damage and respiratory disorders, as well as long-term risks such as cancer and genetic mutations. To address this issue, an community program was conducted for the community in Dusun Gonggangan, Bolon, Colomadu, Karanganyar, involving the local women's community group (PKK). The method employed consisted of education through presentations and interactive Q&A sessions. The materials covered waste identification, segregation, storage, and disposal according to proper waste management standards. Interactive discussions encouraged active community participation to understand and adopt responsible household waste management practices. The results showed an increase in community awareness regarding the proper management of B3 and household pharmaceutical waste. The implementation of appropriate waste management practices is expected to mitigate the negative impacts of waste on health and the environment. Thus, effective waste management contributes to improved public health and supports environmental sustainability and ecosystem preservation.
PENERAPAN TEKNOLOGI POMPA AIR TENAGA SURYA SEBAGAI UPAYA MENAIKKAN PRODUKTIVITAS PERTANIAN PADA KELOMPOK TANI DESA BANYUMAS KABUPATEN SAMPANG MADURA

Published: January 2025

Pulau Madura memiliki potensi pertanian yang sangat besar, namun kendala terbesar yang dihadapi petani adalah ketersedian air untuk sawah yang masih berfluktuasi.  Dampak akhir yang paling dirasakan adalah pertanian di Madura belum bisa membawa kesejahteraan ekonomi kepada para petani.
Melaui program Pengabdian kepada Masyarakat ini, kami dari tim Politeknik Negeri Madura mengimplementasikan sistem irigasi menggunakan pompa air tenaga surya untuk mengairi sawah petani di pulau Madura. Sistem ini diimplementasikan di desa Banyumas kabupaten Sampang melibatkan kelompok tani “Jaya Baru Banyumas”.
Tujuan yang ingin dicapai melalui penerapan sistem pompa air tenaga surya ini adalah untuk menjaga stabilitas ketersediaan air pada sawah sehingga dapat meningkatkan produktivitas pertanian. Selain itu, sistem pompa air tenaga surya ini dapat menurunkan biaya operasional pengairan sawah yang biasaya menggunakan pompa diesel.
Program  Pengabdian kepada Masyarakat ini  juga melibatkan mitra pesantren As-Salam di desa Banyumas untuk penggunaan lahan instalasi PV. Sebagai kompensasi penggunaan lahan, Pesantren mitra akan memperoleh sharing daya listrik yang dibangkitkan PV selama musim penghujan dimana kebutuhan air sawah petani diperoleh dari air hujan.

Published: January 2025

Concrete is a widely used construction material, but its production has a negative impact on the environment. This study aims to determine the effect and optimal percentage of using palm kernel shells and coconut fiber in concrete mixtures on the compressive strength of concrete. The research method involved making a variety of concrete mixes with the replacement of conventional aggregates by palm kernel shells as coarse aggregate and coconut fiber as fine aggregate. Four mix variations were tested: A (1% coconut fiber, 5% palm kernel shell), B (2% coconut fiber, 5% palm kernel shell), C (1% coconut fiber, 10% palm kernel shell), and D (2% coconut fiber, 10% palm kernel shell). Compressive strength testing was conducted at 7, 14, and 28 days of concrete age. The analysis showed that variation A, with 1% coir and 5% palm kernel shell, produced the closest compressive strength to normal concrete. ANOVA tests confirmed the significant effect of these mixtures on compressive strength. The contribution of this research lies in the development of alternative concrete materials that are more environmentally friendly, utilizing agricultural waste to reduce dependence on natural resources and lower the carbon footprint of the construction industry.
