Profesi pekerjaan sosial adalah profesi praktik dan disiplin ilmu yang fokusnya adalah mendorong terjadinya perubahan dan pembangunan sosial, kohesi sosial dan pemberdayaan serta pembebasan manusia. Populasi disabilitas adalah populasi yang mengalami banyak kekerasan dan penindasan serta ketidakterpenuhan hak, padahal Indonesia sudah memiliki payung hukum yang memandatkan pemerintah Republik Indonesia untuk memenuhi hak orang dengan disabilitas. Dengan menggunakan metode kajian literatur, tulisan ini bertujuan untuk menjabarkan praktik pekerjaan sosial dengan populasi disabilitas di Indonesia. Hasil penelitian menunjukkan bahwa pekerjaan sosial sebagai profesi pertolongan bekerja dengan populasi disabilitas di tiga bidang praktik yaitu praktik mikro, mezzo dan makro. Saat bekerja dengan populasi disabilitas, pekerja sosial harus selalu melibatkan orang dengan disabilitas sebagai subjek dan mengkonsultasikan hal-hal berkenaan dengan pemenuhan hak mereka dengan orang dengan disabilitas itu sendiri. Dengan melakukan hal tersebut, pekerja sosial akan terhindar dari praktik oppresif terhadap populasi disabilitas. Social work profession is a practice profession and an academic discipline focusing on the fostering of social change and social development as well as social cohesion and empowerment and human freedom. Disability population is one population experiencing many violations and oppression along with unfulfillment of their rights, whereas Indonesia has the legal umbrella mandating the government of Indonesia to achieve the fulfilment of the rights of people with disability. Using study literature method, this article is aiming at describing the social work practice with disability population in Indonesia. The result shows that social work as a helping profession working with disability population in three field of practice, namely micro, mezzo and macro. During working with disability population, social workers have to always involving the people with disability as the subjects and consult on every aspect of their rights fulfilment with the disability population themselves. By doing so, social workers will be protected from conducting oppressive practice toward the disabled population.

Kebaradaan sengketa lahan dan konflik tanah dapat merusak tatanan hukum dan menghambat pembangunan bangsa Indonesia, sehingga diperlukan strategi yang tepat dalam setiap penyelesainnya. Penelitian ini bertujuan untuk mengetahui bagaimana menyusun strategi yang tepat dalam menyelesaikan setiap konflik/sengketa tanah yang sering terjadi di negara Indonesia, adapun metode penelitian yang digunakan oleh peneliti yakni, metode kualitatif dan bersifat deskriptif analitis. Maka hasil dari penelitian ini menjabarkan bahwa, sengketa lahan terjadi karena lahan mempunyai kedudukan yang sangat penting, yang dapat membuktikan kemerdekaan dan kedaulatan pemiliknya. Tidak semua masalah harus diselesaikan lewat persidangan atau pengadilan. Saat ini telah lahir penyelesaian sengketa non litigasi, yaitu Alternative Dispute Resolution (selanjutnya disebut dengan ADR), salah satunya dengan menggunakan mediasi di mana keberpihakan seorang mediator tidak terjadi dalam persoalan mediasi. Selain itu masyarakat juga dapat melibatkan seorang pekerja sosial dalam membantu menyelesaikan konflik/sengketa lahan yang sedang dihadapi, pekerja sosial adalah mereka yang tepat untuk terlibat dalam proses Resolusi konflik, seperti menjadi Negosiator ataupun Mediator. Dalam penyelesaian konflik sengketa lahan, seorang pekerja sosial memerankan sebagai “fungsi kekuatan ketiga” untuk menjembatani antara anggota kelompok dan sistem lingkungan yang menghambatnya. Selain itu pekerja sosial mampu menjadi Fasilitator dalam penyelesain konflik sengketa lahan dengan memberikan suatu kepastian damai antara pihak-pihak yang terlibat konflik. The existence of land disputes and land conflicts can damage the legal order and hinder the development of the Indonesian nation, so appropriate strategies are needed in each resolution. This research aims to find out how to develop appropriate strategies in resolving every land conflict/dispute that frequently occurs in Indonesia. The research methods used by researchers are qualitative and analytical descriptive methods. So the results of this research explain that land disputes occur because land has a very important position, which can prove the independence and sovereignty of its owner. Not all problems have to be resolved through trial or court. Currently, non-litigation dispute resolution has emerged, namely Alternative Dispute Resolution (hereinafter referred to as ADR), one of which uses mediation where a mediator's partiality does not occur in mediation issues. Apart from that, the community can also involve a social worker in helping resolve the land conflict/dispute they are facing. Social workers are the right people to be involved in the conflict resolution process, such as being a Negotiator or Mediator. In resolving land disputes, a social worker acts as a "third force function" to bridge between group members and the environmental system that hinders them. Apart from that, social workers are able to become facilitators in resolving land disputes by providing a guarantee of peace between the parties involved in the conflict.

The conflict covers various aspects, such as inter-ethnic conflicts and religious conflicts, which indicate the existence of tensions between groups in society. In the context of handling social conflict, a social harmony program is needed that can provide comprehensive social benefits. However, there is a gap between research results that highlight the complexity of social conflict from various perspectives and the need for holistic and integrated social policies in handling social conflict in Indonesia. Therefore, further research is needed to measure the social benefits generated by social harmony programs as well as in-depth evaluations related to the efficiency of resource use and program effectiveness in achieving social harmony objectives. In addition, the cost aspect is also an important consideration in handling social conflict, such as the cost of treating depression and psychosocial disorders. Thus, further research in this regard will make a significant contribution to the development of policies for handling social conflict in Indonesia.

El pronóstico de actividad eléctrica es de vital importancia para muchas actividades y la seguridad de las personas. Dicho pronóstico no es sencillo debido a que es un proceso que ocurre a escalas que no son resueltas por los modelos meteorológicos. Por este motivo, el presente trabajo evalúa el desempeño de cinco parametrizaciones aplicadas al modelo WRF con convección permitida. Para generar y evaluar las parametrizaciones se utilizaron los pronósticos determinísticos y por ensamble del Sistema de Asimilación y Pronóstico del Servicio Meteorológico Nacional (SAP.SMN) y las observaciones del sensor GLM entre noviembre de 2022 y abril de 2023. Se encontró que todas las parametrizaciones logran representar de manera correcta distintas características de las descargas observadas durante el período analizado, siendo la que se basa en el contenido de hielo integrado en la vertical, la que brinda los mejores resultados. Se observó además una sensibilidad a la parametrización de la microfísica empleada en el modelo, no así con la parametrización de la capa límite.

Published: February 2025

The study presents a numerical analysis and experimental verification of deflection of the elements of the band that forms the superstructure of a medium-sized fire-fighting and rescue vehicle. The conducted tests were aimed at the selection of the FEM numerical model enabling the identification of the strain of the structure and the determination of the state of deformation under operational loads. The numerical tool used for the analysis was the Ansys software. Based on the conducted tests, it was possible to identify the key areas of the band in which the occurrence of the highest loads is predicted. The use of a numerical solution allows for determining the safe performance level of the designed element before putting it into production. It allows, among other things, to estimate the maximum deflection of a cross-section of a given length loaded perpendicularly and parallel to the direction of extrusion. The cases analyzed in the work are important from the point of view of their application in the construction of a medium rescue and firefighting vehicle.

Published: February 2025

This article examines demographic shifts and changing housing needs in Latvia, with a focus on their implications for social housing policy. Latvia faces significant demographic challenges, including population decline, rapid ageing, and changing household structures. The study analyses historical trends in population, age structure, household composition, and migration patterns based on data from the Latvian Central Statistical Bureau and Eurostat. It also assesses the current housing landscape, including characteristics of housing stocks, homeownership rates, rental market dynamics, and social housing provision. The research reveals a growing mismatch between the existing housing stock and evolving needs, particularly for smaller, accessible units suitable for an ageing population. Based on these findings, the article proposes policy recommendations to address Latvia’s evolving housing needs. These include short-term adjustments to current policies, long-term strategic planning for housing development, and innovative financing mechanisms for social housing. The study also explores potential challenges in implementing these recommendations, such as funding restrictions and political acceptance. By aligning housing policy with demographic realities, Latvia can better meet the needs of its changing population and enhance the overall quality of life of its citizens. This research contributes to a better understanding of the adaptation of housing policy adaptation in the context of significant demographic change.

Published: February 2025

In the modern global field of underground water treatment, the technology of biological iron removal is gaining more and more recognition, as it has a number of significant advantages compared to traditional ones, namely: increased rates of Fe(II) oxidation, filtration, as well as a large dirt capacity of the filter filling. Therefore, the search for methods to activate cellular metabolic processes has practical implications. One of the possible ways of such activation is by using the effect of a constant magnetic field (CMF) on communities of ferrobacteria attached to the contact loading of bioabsorbents made of synthetic material. Based on the results of the research, it has been established that the CMF with an induction value of 5–10 mT is the most favorable for the development of ferrobacteria colonies, while the induction of 130–150 mT, on the contrary, inhibits their development. There has been studied the effect of CMF with the power of 10–15 mT on the e ciency of combined processes of treatment from dissolved organic compounds and Fe(II). The results of comparative studies on the effectiveness of various technological schemes are presented. It was found that with the use of CMF with a magnetic induction of 5–10 mT, the effect of iron removal increases by 20%. There has been developed biotechnology for treating weak acid (pH 6.3–6.5), iron-containing (Fe2+ 6–8 mg/dm3) underground waters which is based on the combinatorics of physical (aeration, influence of constant magnetic field) and biochemical (use of ferrobacteria consortia) methods. The main technological parameters of the process: filtration rate for the bioreactor 7–10 m/h, for filters 6–8 m/h; duration of filter cycles for the bioreactor is 2–3 weeks; for filters 44–48 hours have been determined. The theoretical aspects of the impact of CMF on the processes of biochemical treatment of underground water have been substantiated.

Authors: Bilski Jarosław , Kowalczyk Bartosz , Dymova Ludmila , Xiao Min
Published: February 2025

This paper introduces a significant advancement in neural network training algorithms through the development of a Fast Scaled Givens rotations in QR decomposition (FSGQR) method based on the recursive least squares (RLS) method. The algorithm represents an optimized variant of existing rotation-based training approaches, distinguished by its complete elimination of scale factors from calculations while maintaining mathematical precision. Through extensive experimentation across multiple benchmarks, including complex tasks like the MNIST digit recognition and concrete strength prediction, FSGQR demonstrates superior performance compared to the widely-used ADAM optimizer and other conventional training methods. The algorithm achieves faster convergence with fewer training epochs while maintaining or improving accuracy.In some tasks, FSGQR completed training in up to five times fewer epochs compared to the ADAM algorithm, while it achieved higher recognition accuracy in the MNIST training set. The paper provides comprehensive mathematical foundations for the optimization, detailed implementation guidelines, and extensive empirical validation across various neural network architectures. The results conclusively demonstrate that FSGQR offers a compelling alternative to current deep learning optimization methods, particularly for applications requiring rapid training convergence without sacrificing accuracy. The algorithm’s effectiveness is particularly noteworthy in feedforward neural networks with differentiable activation functions, making it a valuable tool for modern machine learning applications.
Various scenarios of measurements using a smartphone with a LiDAR sensor in the context of integration with the TLS point cloud
Authors: Janicka Joanna , Błaszczak-Bąk Wioleta
Published: February 2025

Smartphones with Light Detection and Ranging (LiDAR) sensors are increasingly used for engineering measurements. Although the processing of the acquired point clouds seems similar to the processing of point clouds measured with, for example, a terrestrial laser scanner, processing data from a smartphone requires a special approach, first of all, when it comes to methods of obtaining and registering point clouds to obtain one complete metric point cloud. The research consisted of comparing various scenarios of measuring using a smartphone with a LiDAR sensor (a smartphone held in hand, a smartphone on a selfie stick, and a smartphone mounted on a gimbal), two acquisition strategies (one direction and zigzag) and two registration methods (point to point and cloud to cloud). The aim of the study was to find the best solution for registering the obtained point cloud with referenced terrestrial laser scanning (TLS) point cloud. It turns out that how we obtain field data using a smartphone with a LiDAR sensor is important and affects the accuracy of point cloud integration. The results showed that the use of additional devices such as a gimbal supports the data acquisition process and has an impact on the point cloud registration. In the analysed case, the RMSE registration error was the smallest and amounted to 0.012 m and 0.019 m, while the largest registration error was 0.060 m and 0.065 m, for object 1 and object 2, respectively. The result obtained using the proposed methodology can be considered satisfactory.

Jembatan kereta api merupakan salah satu struktur pendukung pada perlintasan perkeretaapian yang berfungsi untuk menghubungkan antara daratan yang terpisahkan oleh sungai, jurang dan lainnya. Dalam perencanaan jembatan harus direncanakan dapat menahan gempa bumi atau bencana lainnya agar menjamin keselamatan dan kenyamanan masyarakat. Beban gempa bumi dapat menyebabkan suatu struktur tidak lagi berperilaku linier melainkan berprilaku nonlinier sehingga analisis nonlinier diperlukan. Salah satu metode yang dapat digunakan yaitu analisis nonliner time history, dimana analisis tersebut dilakukan untuk mengetahui respon dari struktur atas jembatan akibat beban gempa. Untuk mengetahui pengaruh dari beban gempa terhadap struktur atas jembatan BH-537 dapat menggunakan nilai Dynamic Amplification Factor (DAF). Nilai DAF diperoleh dari perbandingan antara respon analisis dinamis dan analisis statis. Nilai DAF yang diperoleh yaitu; displacement arah x (1,000 – 80,299), displacement arah y (1,043 – 1,548), displacement arah z (1,000 – 1,001), dan gaya dalam (1,000 – 1,016). Berdasarkan hasil tersebut dapat disimpulkan bahwa bagian yang menerima pengaruh dari beban gempa yaitu berada pada joint 37 dengan nilai DAF yang diperoleh yaitu 80,229 atau nilai displacement yang disebabkan oleh beban dinamis gempa memiliki nilai 80 kali lebih besar dibandingkan dengan beban statis pada struktur atas jembatan BH-537.

VISSIM adalah software mikro-simulasi arus lalu lintas multimoda yang digunakan secara luas dalam menentukan kinerja lalu lintas dan perencanaan alternatif. Namun, karena pengaturan bawaan dari perilaku pengemudi yang disimulasikan berbeda dengan kondisi di lalu lintas di Indonesia, kalibrasi diperlukan. Penelitian ini bertujuan untuk mengidentifikasi cara mendapatkan data driving behavior, melakukan kalibrasi, dan validasi sehingga hasil simulasi VISSIM merepresentasikan kondisi eksisting. Penelitian dilakukan melalui survei lapangan dengan mengamati perilaku kendaraan dan mengukur jarak antar kendaraan. Proses kalibrasi yaitu penyesuaian parameter perilaku pengemudi driving behavior sampai pemodelan dapat valid. Hasil dari Validasi menunjukkan bahwa setelah sekali kalibrasi, nilai GEH pada setiap kaki simpang < 5, menandakan model diterima dan valid. Hasil MAPE pada kaki simpang Selatan dan Utara < 10 (Sangat Baik), sedangkan pada kaki simpang Barat berada pada rentang 10-20 (Baik). Analisis menunjukkan bahwa nilai GEH dan MAPE yang diuji dalam sekali kalibrasi menunjukkan nilai yang valid. Dari hasil tersebut, dapat disimpulkan bahwa observasi langsung dapat menjadi metode yang efektif dalam mendapatkan parameter driving behavior. Hasil kalibrasi dan validasi menunjukkan bahwa model VISSIM dapat merepresentasikan kondisi eksisting dengan baik. Peran parameter driving behavior sangat penting dalam kevalidan pemodelan VISSIM. Dari pembahasan dapat disimpulkan bahwa nilai driving behavior yang selama ini menggunakan angka dari kajian-kajian sebelumnya atau dengan trial and error sebenarnya dapat dicari dengan cara survei langsung dengan hasil yang lebih cepat dan efektif.
PENGARUH UKURAN BENDA UJI KUBUS TERHADAP NILAI KUAT TEKAN RECATIVE POWDER CONCRETE
Authors: Kushartomo Widodo , Sutandi Arianti , Wijaya Jevin
Published: February 2025

The testing of reactive powder concrete (RPC) in the laboratory aims to obtain compressive strength values that represent the quality of the concrete being tested. This testing must adhere to established standards, including international regulations such as ASTM (American Standard for Testing Materials), BS (British Standard), and national regulations like SNI. According to BS 1881 Part 108, the concrete samples must be cube-shaped with dimensions of 15 cm x 15 cm x 15 cm. For high-strength concrete such as RPC, it is impractical to use cylindrical specimens with a diameter of 15 cm and a height of 30 cm due to the maximum capacity of the compression testing machine. This study investigates the correlation between compressive strength for cube specimens of 5x5x5 cm³, 10x10x10 cm³, and 15x15x15 cm³. The target compressive strengths are set at K400, K500, and K650, with 10 samples produced for each size and strength class. Compressive strength tests were conducted at 28 days, with the samples cured through immersion in water at 25°C for 26 days. The results indicate that specimen size influences compressive strength values, with smaller specimens exhibiting higher compressive strengths. Conversely, larger specimens are more prone to defects, which may reduce the compressive strength.

Pengujian harus mengikuti standar-standar yang telah ditentukan seperti bentuk dan ukuran yang  sesuai dengan peraturan internasional seperti ASTM (American Standart for Testing Materials), BS (British Standard), dan peraturan nasional yaitu SNI. Berdasarkan BS 1881 part 108 tentang sampel beton berbentuk kubus, mensyaratkan ukuran benda uji 15 cm x 15 cm x 15 cm. Pada beton dengan mutu sangat tinggi seperti RPC, tidak memungkinkan membuat benda uji silinder berukuran diameter 15 cm tinggi 30 cm, ini berkaitan dengan kapasitas maksimum mesin yang digunakan untuk melakukan pengujian tekan. Pada penelitian ini dicari korelasi kuat tekan ukuran kubus  5x5x5 cm3, 10x10x10 cm3 terhadap 15x15x15 cm3. Kuat tekan beton yang direncanakan K400, K500 dan K650, masing masing ukuran dan mutu benda uji dibuat sebanyak 10 buah. Pengujian benda uji kubus dilakukan pada umur 28 hari, pemeliharan dengan teknik perendaman dalam air bertemperatur 25oC selama 26 hari. Berdasarkan pengujian yang dilakukan ukuran benda uji mempengaruhi nilai kuat tekan, semakin kecil ukuran benda uji maka nilai kuat tekan yang ditunjukkan juga semakin besar. Semakin besar benda uji kubs yang digunakan, kemungkinan terjadinya cacat juga semakin besar.

OBJECTIVE: To compare the weight-height development of children with adenotonsillar hypertrophy in relation to the normal growth curve.
METHOD: Prospective study with a target population of children with tonsil hypertrophy submitted to adenoidectomy and/or tonsillectomy. The information was acquired before the surgical procedure through a questionnaire for those responsible, who evaluated gender, age, weight, height, body mass index and main complaint.
RESULT: We analyzed 52 patients with indication of tonsillectomy between three and eleven years. Most children were eutrophic, 30.8% of the children were above ideal weight and 3.8% were under the ideal weight. Regarding the height-by-age ratio, 96.15% of the children had adequate height and 3.85% had short stature for age. The main complaints that led children to medical care were snoring, chronic tonsillitis, mouth breathing and recurrent airway infections. The main complementary examination requested was cavum radiography.
CONCLUSION: There was no direct relationship between tonsil hypertrophy and weight-height growth deficit in the studied children. Only a small increase in the rate of overweight and obesity was observed in older children, but without statistical significance.
Between Money and the Planet? The Interests of Post-colonial Countries in Climate Negotiations
Authors: Purba Elbinsar
Published: February 2025

This paper explores the interests of post-colonial countries in climate negotiations. It does so by analysing what they need and demand as a consequence of injustice and damages caused by colonialism, which have not been extensively discussed in the current literature. Using content analysis as a methodological approach, the author collected and examined country statements delivered at the Conferences of the Parties (COP) of the United Nations Framework Convention on Climate Change (UNFCCC). The analysis reveals that there are three needs and three demands that commonly lie in the interest of formerly colonised countries. Among them, securing financial resources stands high in their priority. However, this does not mean that provision of funding lessens their perception of historical injustice. They still demand for substantive actions from developed countries to correct the past wrongdoings. While some experts suggest transfer of more resources from the Global North to the Global South to ease the climate decision making process, this paper highlights that although such measure might help build trust, it does not necessarily break the deadlock in climate negotiations.
Self-learning AI in Educational Research and Other Fields

There are several areas where self-learning AI is actively used. Machine learning and deep learning allow you to identify patterns and improve performance. Algorithms such as neural networks can adapt and improve based on experience. Self-learning GPTs are used to dialogue with humans. Computer vision recognizes and classifies images. Recommender systems analyze user preferences and offer personalized solutions. Adaptive robotic industrial control systems can optimize processes by adapting to changing conditions and data. Self-learning intelligent systems help detect and respond to new threats and attacks by analyzing network traffic and user behavior. These technologies continue to evolve, opening up new research opportunities for students in the field of education. Self-learning AI helps programs learn, draw conclusions, and use them in the future. Programming languages do not consider algorithms as data. Programs do not have access to themselves. To learn, you need to change, and for this you need to have access to your own code. Then self-learning becomes possible. By generating the logic of self-learning algorithms, they can improve the program, it becomes different from its source code, and these changes must be saved. The interpreter of the algorithm improves the intelligence of the program, and it becomes the author of optimal solutions. The programming language of self-learning algorithms Author allows students to form the logic of self-learning algorithms to create intelligent systems that can help them in research activities. These systems are able to independently improve their skills and accuracy without explicit programming for each new type of task.

Completing a thesis is a major academic milestone but often leads to fatigue, stress, and academic burnout. This study examined the roles of academic self-efficacy (an internal factor) and peer support (an external factor) in academic burnout among 7th-semester psychology students completing a 3.5-year thesis at Atma Jaya Catholic University of Indonesia. The study used a quantitative predictive design with 61 participants from the 2020 cohort. Data were collected using the Maslach Burnout Inventory–Student Survey (MBI-SS), The Academic Self-efficacy Scale, and the Peer Support Scale. Multiple linear regression analysis was conducted to assess the relationships among the variables. Results indicated that academic self-efficacy and peer support together significantly influenced academic burnout. Academic self-efficacy showed a significant negative contribution, while peer support had a negative but nonsignificant effect. Burnout levels among participants ranged from moderate to low, while academic self-efficacy and peer support levels were high. Future research could explore the relationship between 3.5-year thesis completion and positive psychological variables related to academic achievement at the Faculty of Psychology, Atma Jaya Catholic University of Indonesia.

In cyber bullying cases, there are three categories of parties involved, such as perpetrators, victims, and bystanders. This study analyzed the overview of victim attribution in reinforcer bystanders involved in cyberbullying incidents among Generation Z. This study uses qualitative methods with a semi-structured interview. The study shows that individuals’ perspectives on tolerating cyberbullying events vary. The four participants who were bystanders in the cyberbullying showed both victim attribution aspects, which are dehumanization and attribution of blame. Participants tend to blame the victim when they think that the victim is at fault. Therefore, in certain cases of cyberbullying, participants tend to normalize or consider it appropriate for cyberbullying to occur.
GAMBARAN ACTIVE PROCRASTINATION PADA MAHASISWA YANG SEDANG MENGERJAKAN SKRIPSI

Published: February 2025

Completing a thesis is a key requirement for undergraduate students, but the process often presents various challenges. In response, some students engage in maladaptive behaviors such as procrastination. While traditionally viewed as detrimental, recent studies have identified a positive form of procrastination called active procrastination. This involves intentionally delaying tasks, feeling motivated under time pressure, meeting deadlines, and achieving satisfactory results. Active procrastination can serve as a productive strategy with potential benefits for undergraduates. This study explored the prevalence and levels of active procrastination among thesis-writing undergraduates. Data were collected from 298 students across universities in Indonesia using convenience sampling. The Active Procrastination Scale-Bahasa Indonesia by Purwanto and Natalya (2019) was employed to measure active procrastination. Findings revealed that thesis students generally exhibit low levels of active procrastination. Additionally, no significant gender differences were observed. The study also found significant correlations among the dimensions of active procrastination. These results suggest that promoting active procrastination may help students adopt a more adaptive approach to managing thesis-related challenges.
