PT Menara Riau Perkasa is a company engaged in the rental of heavy equipment. The maintenance process unscheduled mobile crane heavy equipment is quite long within 5 days including overtime and rest hours and 1 day is inspection. Ordering heavy equipment for 6 days so that the company is often in a hurry for the maintenance process. Therefore, optimization of mobile crane maintenance is carried out by measuring the duration of each maintenance process using the Critical Path Method (CPM). This method is used to identify tasks needed in completing the project and determine scheduling flexibility. This method can complete the maintenance process with an effective time of 2.8 days with 8 hours of operation without rest hours and inspection for 1 day so that the total completion is 3.8 days. The use of the CPM method can reduce the maintenance process time because there are 2 main maintenance process activities that can be done at once with limited leeway time for the battery water process and hydraulic repairs.

Published: January 2025

The oil and gas industry carries high operational risks, particularly in metering system calibration activities. This research uses the Job Safety Analysis (JSA) method to find and examine possible risks in PT. X's metering system calibration procedure. Direct observation, conversations with engineers and HSE teams, and an examination of pertinent papers were used to gather data. Risk analysis was performed using a semi-quantitative approach by assessing the likelihood and severity levels for each identified potential hazard. The research identified 12 potential risks distributed across three categories: low risk (25%), medium risk (66.67%), and high risk (8.33%). The highest risk was found in the power transmitter isolation phase with electrocution hazard. Based on these findings, risk control recommendations are formulated which include training and certification, procedures, engineering controls and proper use of PPE. The implementation of comprehensive and systematic risk control is key to ensuring work safety and the extinction of company operations.
GRAMMATICAL AND LEXICAL IN INFORMAL CONVERSATION OF TEENAGER IN SUKABUMI CITY ON SUNDANESSE MAINTENANCE
Authors: Sri Rahayu
Published: January 2025

Indonesia has hundreds of regional languages which are the mother tongue for the society of each region. Sundanese is the second largest language in Indonesia with 32.4 million speakers (Ajeng Wirachmi Litbang MPI Friday, January 21, 2022). Sukabumi cultural observers claim to be concerned about the continuity of adolescent language among adolescents endangered, even though at all levels of education Sundanese learning materials are still scheduled in schools, Sukabumi (Pikiran Rakyat, March 14, 2018) Based on a survey from the author that almost 90% of parents who have teenagers provide Indonesian as a first language for their children. This condition is caused by the position of Indonesian as official language, unity language, national language so that its use is much wider than regional languages. Sundanese language will turn to the minority and it is danger situation if the teenager in kota Sukabumi do not use Sundanesse. The purpose of this study is to find out how grammatical and lexical Sundanese in informal conversations of teenagers in Sukabumi city and know their sika about their regional language. The methodology used in this study is descriptive qualitative by analyzing grammatical and lexical informal adolescent conversation. This study also collected data with a number of questions in the form of questioners on 20 adolescents and 20 parents. The findings in this study revealed that the grammatical that appears in adolescent conversations is the use of Sundanese affixes used in Indonesian and some words in Indonesian influenced by Sundanese phonemes. Lexical that tends to appear are simple verbs, synonym and repetition. The teenager's attitude towards Sundanese revealed that 50% of the teenagers used Sundanese at home, the rest, 48% mixed Indonesian and Sundanese, and only 2% only used Indonesian.

Narratives of the First World War: Multiple Jewish Perspectives
Authors: Molisak Alina
Published: January 2025

Using literary texts, this chapter analyses the reactions of German and Polish Jews to the First World War. German Jews were, for the most part, initially supportive of the war; however, disillusionment followed defeat and the heavy casualties that resulted. The initial ambivalence towards the war expressed by most Polish Jews did not disappear but was, rather, reinforced by the experience of violence and pogroms. Among both German and Polish Jews after the war, there were hopes for the establishment of harmonious relations between Jews and their neighbours within the new political and social order that emerged in Europe. However, these did not prove lasting, and the new political system soon found itself in a serious crisis, with threatening consequences for the Jews in both countries.
The
Polenaktionen
of October 1938 and September 1939: From Expulsion to Extermination
Authors: Bothe Alina
Published: January 2025

This chapter discusses the two
Polenaktionen
of 1938 and 1939. In October 1938 Nazi Germany forced more than 17,000 Jews with Polish citizenship to cross the border into Poland. There, they became refugees, cared for by the Polish Jewish communities and seen by the Polish government as merely a pawn in international politics. In September 1939, shortly after the German invasion of Poland, at least 5,000 Jewish men with Polish or former Polish citizenship were arrested in Germany and taken to the camps of Buchenwald, Dachau, and Sachsenhausen. Most perished, while a few were freed after an exceptional act of Jewish resistance. Both
Polenaktionen
were unique measures of persecution of Jews with Polish passports. They constituted an important stage in the transition of Nazi policy from expulsion to mass murder.
Enduring Taboos: Jewish Life in Post-War Germany, 1945–1960
Authors: Cronin Joseph
Published: January 2025

This chapter investigates four taboos that have structured research into Jewish life in post-Holocaust Germany. These are, firstly, the hostility between east European displaced persons and German Jews in newly re-established Jewish communities; secondly, the conflict between these Jewish communities and international Jewish organizations surrounding restitution claims; thirdly, the existence of Jewish life—and antisemitism—in socialist East Germany; and fourthly, the phenomenon of ‘returnees’—German Jewish exiles who returned (often from Israel) to West Germany in the 1950s. The chapter examines some of the most important contributions to each of these topics and considers why they became taboos.
The Role of Ammonia in the Distribution of Volatiles in the Primordial Hydrosphere of Europa
Authors: Amsler Moulanier Alizée , Mousis Olivier , Bouquet Alexis , Glein Christopher R.
Published: January 2025

The presence of a hydrosphere on Europa raises questions about its habitability, and studies of its volatile inventory can provide insight into its formation process. Different scenarios suggest that Europa's volatiles could be derived from cometary ices or devolatilized building blocks. The study of post-accretion processes—in particular, the “open-ocean” phase that likely occurred before the formation of the icy crust—is crucial to distinguishing these origins, as this phase is likely to have influenced the volatile inventory. The abundance of ammonia in Europa's building blocks is also crucial for understanding the composition of its ocean and primordial atmosphere. We aim to investigate the ocean–atmosphere equilibrium during the post-accretion period by varying the ammonia fraction in the atmosphere. Our model evaluates the vapor–liquid equilibrium of water and volatiles, as well as the chemical equilibrium within the ocean, to study Europa's early hydrosphere. We explore two initial conditions: one in which Europa's hydrosphere originates from comet-like building blocks, and another in which it forms in equilibrium with a thick-and-CO2-rich atmosphere. In both scenarios, the initial ratio of accreted CO2 to NH3 determines the magnitude of their partial pressures in Europa's early atmosphere. If this ratio exceeds a certain threshold (set to 10−4 in this study), the atmosphere will be CO2-rich; otherwise, it will be CO2-depleted, by multiple orders of magnitude. Overall, our work provides an initial assessment of the distribution of primordial volatiles in Europa's primitive hydrosphere and provides a baseline for interpreting data from the upcoming Europa Clipper mission.
Current-sensorless robust sliding mode control for the DC-DC boost converter
Authors: Oucheriah Said , Azad Abul
Published: January 2025

A current-sensorless PWM-based robust sliding mode controller is proposed for the DC-DC Boost Converter, a nonminimum phase system that presents major challenges in the design of stabilizing controllers. The development of the controller requires the measurement of the output voltage and the estimation of its derivative. An extended state observer is developed to estimate a lumped uncertainty that comprises the uncertain load and input voltage, the converter parasitics, and the component uncertainties, and also to estimate the derivative of the output voltage. A linear sliding surface is used to derive the controller that is simple in its design and yet exhibits excellent features in terms of robustness to external disturbances, parameter uncertainties, and parasitics, despite the absence of the inductor current feedback. Also, a simple procedure to select the controller gains is outlined. The robustness of the controller is validated by computer simulations.
Dynamics and density function of a HTLV-1 model with latent infection and Ornstein-Uhlenbeck process
Authors: Ren Yan , Cheng Yan , Chai Yuzhen , Guo Ping
Published: January 2025

This paper examines the propagation dynamics of a T-lymphoblastic leukemia virus type Ⅰ (HTLV-1) infection model in a stochastic environment combined with an Ornstein-Uhlenbeck process. In conjunction with the theory of Lyapunov functions, we initially demonstrate the existence of a unique global solution to the model when initial values are positive. Subsequently, we establish a sufficient condition for the existence of a stochastic model stationary distribution. Based on this condition, the local probability density function expression of the model near the quasi-equilibrium point is solved by combining it with the Fokker-Planck equation. Subsequently, we delineate the pivotal conditions that precipitate the extinction of the disease. Finally, we select suitable data for numerical simulation intending to corroborate the theorem previously established.

Destination Competitiveness, Culture and Heritage Tourism, and Regional Clusters
Authors: Zivanovic Marija Lazarev
Published: January 2025

In recent decades, research on cultural identity, state dynamics, and destination competitiveness has gained significant importance in the field of Cultural and Heritage Tourism. Specifically, in Macedonia, a region shared between two states—North Macedonia and Greece—tourism development occurs within a unique political and economic context. Does dissonant heritage hinder or promote destination development? This chapter aims to assess the destination competitiveness of Culture and (dissonant) Heritage tourism, focusing on the development of regional clusters. Perspectives from various stakeholders—academics, state officials, and tourism strategy developers—are essential. Bridging the gap in service provision and policy-making processes within this demand-led industry requires a shared doctrine. Notably, this introduces an additional perspective to the existing Competitiveness theory. While Culture and Heritage are recognized as core attractors, the dissonant aspect remains unexplored. Balkan states offer opportunities for further research in culture and heritage clusters.

Authors: Gonçalves Pedro Ruben , Sousa Bruno Barbosa , Abreu João , Pereira Manuel Sousa
Published: January 2025

The territorial development strategies constitute an important instrument for the adequate growth and pursuit of development mechanisms transversal to different local dynamics. Territorial Marketing has assumed, in addition to Strategic Planning, a relevant importance in view of the high competitiveness between territories. Territorial Marketing assumes itself as an important working tool in the strategic planning of territories, regardless of its magnitude and typology, enhancing the promotion and development of regions taking into account existing needs and potential. The present chapter is based on an analysis of a very specific territory – Vila de Caldas das Taipas, where gaps and substantial resources are recognized that allow us to develop a plan of action and sustainable strategic development that accompanies general growth. In this sense, an intervention strategy is developed that seeks above all to provide the socio-cultural and economic well-being of the resident population, visitors, and private agents.

Initially, the article will observe the temporal evolution of the built Olympic villages, establishing significant patterns that have followed over time. The evolution of Olympic Village models implies a critical reflection on how host communities experiment with collaborative forms and practices aimed at decreasing the phenomena of social exclusion. The composition of new housing units in central areas of metropolises may foment the emergence of new forms of gentrification or segregation within host cities.
Addressing and Overcoming Destination Rejection From a Destination Management Perspective
Authors: Inanir Ali , Karakuş Yusuf
Published: January 2025

Factors such as the development of technological possibilities, the growth of economies, social changes and the disappearance of borders have led individuals to travel to more distant regions. Depending on this situation, individuals have had to choose among multiple destinations. As a matter of fact, some destinations may be rejected for different reasons. Effective plans and policies should be developed to reduce the rejection of destinations. However, plans and policies to be developed for destination preference will not work in case of destination rejection. Because the consumer will remain a tourism product that is not even involved in the purchase decision process. This book chapter makes some inferences to contribute to the destination management process to eliminate this negative situation.

Published: January 2025

Purpose The purpose is to examine how a territorial brand positions a tourism destination. Design/methodology/approach The strategy used a case study using a qualitative approach. Findings/Conclusion The results highlight the use of the territorial brand and scope-creating local events in urban areas. Studying the territorial brand in the context of cultural studies also extends to the study of tourism. Research limitations The study's shortcoming was that it was limited to cities in the interior. We propose broadening the study to include the realities of other small towns. Practical and Theoretical Implications The contributions address the complexity of the investigated themes, destination branding, place branding, and territorial brand. Originality There are certain places, such as Brazil, where the brand of the place is still embryonic. The territorial brand led from the feeling of local belonging. The reality of the city of Pelotas can reflect the existence of other territorial brands, and this study contributes to exposing this.

Addressing the educational needs arising from this demographic shift is crucial at the early childhood education level, where the foundation for mutual understanding in a multicultural context is established. In this regard, it is vital to underscore the role of Social Sciences education in cultivating democratic citizenship, with the overarching goal of equipping society to make collective, inclusive, and informed decisions that shape its actions. Achieving this requires educators proficient in these competencies, emphasizing the urgent need for strategies that support their professional development. This study aligns with that goal, advocating for cooperative learning, social integration, and solidarity.
Geographic Education and Citizen Participation
Authors: Claudino Sérgio
Published: January 2025

From the transition between the 18th and 19th centuries, the teaching of Geography emphasized the description of large global spaces, aligned with a rationalist perspective suitable for shaping expansionist elites. In the 19th century, this discipline fostered identification with the nation-state through the concept of territory, promoting a conformist form of citizenship. The following century, marked by two world wars and the Cold War, continued these educational traditions. The current century introduces the social appeal of participatory and multi-scalar territorial construction. The Nós Propomos!/ We Propose! Project embraces the challenge of fostering committed and proactive participation in territorial citizenship. Its methodological simplicity (problem identification by pupils, fieldwork, presentation, and sharing of proposals) ensures its applicability even in educational peripheries. The international expansion of the project demonstrates that it provides an alternative educational response, influencing educational practices beyond the boundaries of Nós Propomos! itself.

The Revival of Lucía Baquedano's Work in Youth Literature
Authors: Mora Jesús Guzmán
Published: January 2025

Recovering Lucía Baquedano's work is essential for enriching juvenile literature and highlighting overlooked Spanish women authors. Cinco panes de cebada, Baquedano's novel, reflects rural Spanish life during the late Franco era and the country's modernization. The protagonist, Muriel, an urban teacher in a rural setting, undergoes a journey of adaptation and identity-building as she immerses herself in her new community. Over time, Muriel defies the stereotype of the traditional rural teacher by prioritizing her students' learning and well-being. The novel's confessional tone suggests an autobiographical quality and serves as a potential model for today's educators. The article ultimately argues for the renewed appreciation of works like this in educational contexts, as they address timeless themes such as teacher vocation and the transformative power of education for disadvantaged communities.

Specifically, in the subject of Spanish Language and Literature, incorporating texts from the Hispano-American literary tradition can facilitate the academic and social integration of many Latin American students enrolled in Spanish schools. This article reviews the didactic potential of the work of Horacio Quiroga, considered one of the great masters of the Hispano-American short story, for the simultaneous development of both literary and intercultural competencies. The article analyzes the constructive, formal, linguistic, and thematic characteristics of Quiroga's stories, which not only offer an artistically enriching reading experience but also provide an opportunity for our migrant and native students to engage in intercultural dialogue.
Pre-Service Teachers' Conceptions on the Expressive and Writing Abilities of Current Conversational AI
Authors: Navío-Inglés Maria , Tirado-Olivares Sergio , O'Connor-Jiménez Paula
Published: January 2025

In the post-truth era, where fake news abounds, advancements in artificial intelligence (AI), particularly conversational AI, are producing tools capable of generating increasingly human-like text. This mixed-methods study explores future teachers' perceptions about the ability of conversational AI to write argumentative texts. To this aim, a group of 87 pre-service teachers compared two anonymised texts: an AI-generated one and a text written by a fellow student. Results indicate that most participants believed the AI-generated text would outperform the human-written one in an exam, though opinions were divided on which text conveyed more emotions. Participants generally associated better writing and information richness with AI, while they linked subjectivity and emotivity to the human author. However, not all correctly identified the author of each text, highlighting the need for further preparation of future teachers on current AI abilities and limitations.

Aptamers: promising tool for disease diagnosis and treatment
Authors: Padma K. R. , Don K. R.
Published: January 2025

Aptamers are short, single-stranded DNA or RNA (ssDNA or ssRNA) biomolecules that can selectively attach with specific receptors, including proteins, peptides, carbohydrates, small molecules, hazardous chemicals, and living cells. In the last ten years, aptamers have begun to move away from fundamental research into a variety of industrial applications. The creation of diagnostics is more common than the development of clinical applications since improving the in vivo stability and pharmacokinetics of aptamers for diagnostic tests doesn’t require significant modification. Based on the increased attention, the efficacy of generating aptamers for commercially appealing targets has improved as a result of advances in vitro selection technology `Systematic Evolution of Ligands by Exponential Enrichment (SELEX). Many diseases, including Mycobacterium TB, Treponema pallidum, Novel Coronavirus, HIV, Mucor, and others, revealed substantial menace to people’s well-being and placed significant socioeconomic encumbrance on society. Hence, the initial, as well as precise diagnosis of the pathogen, is crucial for prompt and successful therapy. Due to a lack of reliable probes for identifying the biological markers of infections, detecting human infectious ailments at the molecular as well as nanoscale has been extraordinarily perplexing up to this point. Via the selective growth of ligands by exponential enrichment, a group of plastic oligonucleotides with high specificity and sensitivity known as aptamers are tested in vitro (SELEX). The range of aptamer application situations has expanded significantly with the continued advancement of SELEX-based aptamer screening technologies. This paper reviews the evolution of nucleic acid aptamers in biomedicine with a particular emphasis on how they are used to diagnose infectious diseases. A growing number of pharmaceutical aptamers are currently the subject of preclinical studies or clinical trials. This article discusses the creation and evaluation of therapeutic aptamers for the treatment of various illnesses, including coronavirus. However, the momentous state of aptamer technology suffers from several technical constraints that hinder the passage of innovative aptamers into the clinic and make the aptamer business harder. This review primarily focuses on approaches to overcome obstacles impeding the widespread deployment of aptamers in diagnosis and therapy, as well as tactics that may greatly expand the range of aptamer use and provide future directions to several researchers.

Authors: Singh Neha , Mohanty Suravi , Tirumalae Rajalakshmi
Published: January 2025

Background

Skin diseases constitute a significant burden in the pediatric age group and demand a separate evaluation from adult dermatoses as both vary in mode of presentation, prognosis, and line of treatment.

Objective

To evaluate the histopathologic spectrum of skin biopsies in pediatric noninfectious inflammatory diseases pediatric inflammatory diseases and its correlation with clinical findings.

Patients and methods

This was a retrospective study that included a total of 140 skin biopsies of noninfectious inflammatory dermatoses in children aged up to 18 years. The clinical differential diagnoses were compared with histopathologic diagnoses; concordance and discordance were calculated.

Results

Of the 140 patients, histopathologic diagnoses of 109 (77.9%) patients were concordant with the clinical diagnoses, whereas 23 (16.4%) showed discordance, among which 18 (78.3%) showed major discordance, while the remaining five (21.7%) cases had minor discordance. The remaining eight (5.7%) cases were inconclusive.

Conclusion

Histopathology is still the best tool for diagnosis in the majority of pediatric inflammatory dermatoses. Effective communication between the clinician and the pathologist and thorough clinical correlation enhances the value of the skin biopsies
Melioidosis – An under-recognized dreaded disease in Southeast Asia
Authors: Muthanikkatt Anas Mohammed , Nathan Balamurugan , Uthayakumar Amaravathi , Devendiran Anandhi , Muthu Saravanan
Published: January 2025

Melioidosis is a disease endemic to India but often goes unrecognized, leading to considerable illness and death. We present the case of a 31-year-old man who had a fever of unknown origin, abnormal renal and liver function tests, and negative tests for dengue, typhoid, leptospirosis, and scrub typhus. Imaging revealed multiple splenic infarcts. Initially suspected to be malaria due to its prevalence in South India, further investigation uncovered pneumonia along with several liver and splenic abscesses, raising the possibility of melioidosis. Blood culture eventually identified Burkholderia pseudomallei, confirming the diagnosis. As malaria cases decline in Southeast Asia, emergency physicians should consider melioidosis in their differential diagnosis of acute febrile illnesses, especially in endemic areas. Early detection and prompt antibiotic treatment are vital for managing this often under-recognized disease with a high fatality rate. Thus, melioidosis should be considered in patients with unexplained fever in endemic regions, as early diagnosis and intervention can be life-saving.

Oral presentations had a higher publication rate than poster presentations, indicating higher quality. The authors’ affiliations and the studies’ designs emerged as pivotal factors influencing the success of publication.
Pensar en una justicia espectral: desaparición forzada y fantología
Authors: Serna Covarrubias Luis Fernando
Published: January 2025

Este texto parte de una reflexión en torno a cómo se nombran los sujetos que han sido víctimas de desaparición forzada. Se parte de la idea de que el acto nominativo carga consigo, ya sea una búsqueda de justicia o, al contrario, una forma de preservar la impunidad. Para esto, se hará un análisis de cómo la grafía “desaparecidx” des-ontologiza al sujeto, pues la persona desaparecida habita un espacio entre la vida y la muerte. Así, es necesario pensar en ese sujeto desde la fantología como una lógica del espectro, lo que nos permite salir de una enunciación binaria tradicional. Esta justicia espectral conllevará una responsabilidad infinita hacia la herencia de los espectros que nos acechan. Una lectura de la filosofía del espectro en Derrida y el caso de los 43 estudiantes desaparecidos en Ayotzinapa nos ayudarán a entender la importancia política de conservar la grafía de “desaparición” y no hablar, aún con la localización del cuerpo, de muertxs o vivxs.
Entre la solidaridad ideológica y el interés nacional. México y la guerra civil española, 1936-1939
Authors: Sánchez Andrés Agustín
Published: January 2025

México proporcionó armas y alimentos al gobierno republicano, lo ayudó a sortear el embargo internacional y respaldó diplomáticamente su causa en distintos foros, especialmente en la Sociedad de Naciones. Tradicionalmente se ha considerado que la intervención del gobierno cardenista en la Guerra Civil Española respondió a razones de solidaridad político-ideológica con su único aliado exterior. El artículo plantea que, más allá de dichas razones, la política mexicana hacia el conflicto español obedeció a los objetivos exteriores del régimen cardenista y a las estrategias utilizadas para alcanzarlos en un escenario internacional cada vez más convulso. En un segundo plano, el artículo recapitula las contribuciones de la literatura especializada, en ocasiones complementarias, en otras contradictorias, para determinar el alcance de la participación mexicana en la Guerra de España.

A principios de marzo de 2024, después de más de una década de discusión científica, la Subcomisión de Estratigrafía del Cuaternario (SQS) rechazó la propuesta de confirmar el ‘Antropoceno’ como una nueva época geológica en la Tierra. A pesar de la evidencia presentada por el Grupo de Trabajo del Antropoceno (AWG), que proponía localizar el ‘clavo de oro’ estratigráfico en las sedimentaciones del lago Crawford, en Canadá, debido a los altos niveles registrados de isótopos radiactivos de plutonio, los científicos concluyeron que estos no eran un fenómeno particular suficiente para marcar el inicio general de una nueva época post-Holoceno. En este contexto, la decisión refleja tensiones entre ‘particulares y universales’ vinculadas a tres formas de vulnerabilidad: planetaria, antropológica y tecnológica. El presente trabajo investiga las implicaciones filosóficas de estas tensiones y examina las problemáticas ontológicas derivadas de las resoluciones que intentan conciliar los planos globales y locales. Con este propósito, se confronta el ‘principio de factualidad’ del materialismo especulativo de Meillassoux con el principio antrópico de la hipótesis Gaia y el ‘Novaceno cíborg’ de James Lovelock. Además, se analiza la tesis de la ‘ancestralidad’ no solo como fundamento realista para pensar en un tiempo geológico profundo y posthumano, sino también como argumento para desmontar un sentido hegemónico de la tecnología y la antropología. Finalmente, se concluye en la vital importancia de incorporar a las humanidades planteamientos cosmotécnicos y xenofeministas para construir una nueva universalidad, abriendo caminos para diseñar un mundo de humanos y no humanos.

El presente artículo se centra en el análisis de la invisibilidad de la violencia de género en África, pero se centra en la mujer fang ecuatoguineana. La falta de leyes sancionatorias de la violencia de género hace que se convierta en un problema sin nombre y sin solución en este contexto. Para la comprensión de este fenómeno se ha utilizado una metodología descriptiva y la revisión de la literatura existente sobre esta temática. Para solucionar el problema de la violencia de género, que continúa invisibilizado, se podrían tomar medidas como prohibir las prácticas culturales nocivas para la mujer fang tales como el akus, que constituye uno de los principales óbices para visibilizar esa problemática en la esfera social, política y académica.

Ethiopia's food supply and economy in general are largely dependent on rain-fed agriculture, which is persistently affected by drought. To counteract the recurrent drought, different water harvesting and irrigation schemes were constructed. Similarly, Dengora Earth dam was constructed in East Belesa district in central Gondar, Ethiopia. However, the dam was not functional for a long time due to the silting of the bottom sediment and water outlets. Therefore, the study aimed to transfer water over the dam crest using a low-cost siphon pump for large-scale irrigation. As a result, three siphon pumps with a diameter of three inches were installed. The discharge capacity of one siphon pump in a given reservoir is about 20.80 l/s. In reverse, the motor pump works for about 10 hours with an average fuel consumption of 35 litres per day. The technology was evaluated based on costs, efficiencies, and technical requirements through the wide participation of stakeholders. The siphon pump was selected and well accepted by the beneficiaries, and their feedback was gathered as the technology could be scaled to irrigate more areas without fuel and related costs. Therefore, a siphon pump is feasible for Dengora Earth Dam and similar reservoirs.

Manalagi apples are an agricultural product that is easily damaged. Damage that occurs to Manalagi apples can be inhibited with an edible coating. The edible coating is a coating on the surface of fruit that can maintain quality and extend shelf life. Edible coatings can be made from hydrocolloids, including porang glucomannan. This research aims to determine the quality characteristics of Manalagi apples after being coated with an edible coating. Apart from that, to analyze the effect of glucomannan flour concentration on the quality characteristics of Manalagi apples, the viscosity of the edible coating solution, and the characteristics of the resulting coating and to choose the best treatment using the multiple attribute method. This research uses a Completely Randomized Design (RAL) with three replications. The treatment in this study was a glucomannan flour formulation of 5 levels, namely A0 (without treatment), A1 (0.5%), A2 (0.75%), A3 (1%), A4 (1.25%), carried out for storage for 7 days and observed on days 1, 3, 5, and 7 at room temperature (± 25℃). Porang glucomannan flour in edible coating significantly affected in respiration rate but had no significant effect on weight loss, L color, b color, and total dissolved solids. The best treatment based on calculation results using the multiple attribute method is A2 (0.75%) with the lowest weight loss was 2.97%, the highest L color with a value of 80, the lowest b color with a value of 15.1, the lowest total dissolved solids with a value of 11.6°Brix, the lowest respiration rate with a value of 0.006 ml CO2/gr/hour.

The soil in the Coba area of the Golina watershed at Raya Kobo Valley contains various soluble salts and exchangeable sodium, magnesium, potassium, and calcium. However, excessive concentrations of these elements can affect soil processes and plant growth, with the impact varying based on concentration levels and plant types. To study the salt-affected soils in the area, we excavated one profile from non-irrigated fields and collected ten soil samples at 20 cm intervals in a two-meter profile. The samples were analyzed for chemical properties such as pH, soluble cations and anions, electrical conductivity, exchangeable cations (Ca, Mg, Na, and K), total nitrogen, organic carbon, available phosphorus, exchangeable sodium percentage, sodium absorption ratio, as well as physical characteristics such as soil color, texture, bulk density, and porosity. The analysis revealed that the non-irrigated soil profile had a pH of 7.4 to 8.5, electrical conductivity of 3.1 to 9.7 dsm-1, organic carbon of 0.4 to 1.5%, total nitrogen of 0.09 to 0.27%, available phosphorus of 25 to 46.5 mg kg-1, and a cation exchange capacity of 48.7 to 57.2 cmol (+) kg-1. Considering the top layers of the soil responsible for agricultural purposes, the electrical conductivity, exchangeable sodium percentage, and pH values indicate that the soil can be classified as saline-sodic soil for non-irrigated farmland.
