Abstract

The Koya West area is an agricultural center area in the city of Jayapura. After harvest, some of these agricultural products are sold directly to the market or to consumers, but some must go through a drying process, including corn, shallots and coconut. The drying process is still traditional, namely by relying on solar energy. Problems that occur when drying is done during the rainy season. In addition, the drying process requires a large area because the crops are just spread out on the ground with tarpaulin. In addition to being unhygienic, it will also be very inconvenient when it rains and farmers must save the crops that are in the sun so that they are not damaged. The purpose of this activity is to provide training and assistance in making dryers using UV plastic.

Abstract

The potential natural resources of Keerom Regency, Arso District, especially in the agricultural sector, are very abundant. Corn cob waste produced by farmers is a loss if it is not converted into something more useful. Corn cobs contain cellulose, hemicellulose, and lignin. This content will later be converted into smaller molecules through various treatments to be used as energy. This service aims to provide knowledge and skills to the farming community, on how to process corn cob waste as solid fuel or briquettes. The results of proximate testing or the composition of corn cob briquettes carried out in the Unhas Animal Husbandry Laboratory showed that at the highest temperature of 100oC, fixed carbon was obtained at 39.7, and at the lowest temperature of 60oC, fixed carbon was at 41.3. This can be stated as the amount of carbon contained in the remaining material after the volatile matter has been removed. Likewise, the higher the fixed carbon value, the quality of the corncob briquettes increases. Thus, the highest energy or heat pattern obtained is 5933 cal/gr, so corn cob briquettes can be used as briquette fuel energy. Utilizing corn cobs as fuel for briquettes can reduce dependence on fuel oil and can be used as a home industry business.

Abstract

This community service activity aims to introduce biomass stoves to communities in need, particularly those with abundant biomass waste. The biomass stove's performance has already been evaluated through prior research conducted on campus. This community service initiative will be carried out with the Berkat Rama farmer group in Bibiosi Village, a major corn production area near Cenderawasih University in Arso District, Keerom Regency. Based on preliminary site assessments, local farmers reported significant quantities of agricultural waste, specifically corn cobs, left after harvest. This waste has not been optimally utilized by farmers and is typically disposed of by burning. Motivated by this, our community service team from the Department of Mechanical Engineering at Cenderawasih University aims to introduce corn cob-fueled biomass stoves to the local community. The Community Service Program (PKM) was met with strong enthusiasm from participants, who actively engaged in the socialization session through to its conclusion. The community expressed a desire for more frequent activities of this kind to broaden their knowledge and skills, especially regarding appropriate technology applications. The final outcome of this community service is an increase in both knowledge and skills among members of the Berkat Rama farmer group, specifically in the fabrication and operation of the introduced biomass stoves. They also received training in operational safety for biomass stoves. The acquired knowledge and skills are expected to be applied and shared with other community members and farmers in the area.

Abstract

This research is motivated by the need for the efficiency of the biomass solid fuel drying process in existing dryer installations. This study aims to optimize the insulation on the primary and secondary sides of the spiral heat exchanger and validate the electrical power on the heater register and the heat flow measured by the system. The approach used was the application of a mixture of 25 ml ISO PUR K 760 and 100 ml ISO-PUR K760 Härter (ISO-ELEKTRA Elektrochemische Fabrik GmbH) and the comparison of thermal and electrical power results calculated using temperature difference data between the inlet and outlet of the heater register without readings in a PC regulator. Experiments were conducted with constant parameters, i.e. target temperature 50°C, fan power level 7, and compressor electricity consumption 541 W. This study proves that after sealing the spiral heat exchanger, there is an increase in energy consumption efficiency. In addition, the approach based on temperature difference in calculating heat power can improve the accuracy in observing energy in the biomass drying system.

Abstract

This study aims to analyze the production of charcoal from acacia wood (Acacia spp.) as a sustainable energy alternative, considering the depletion of fossil fuel reserves and the abundance of acacia biomass in Indonesia. The carbonization process was conducted through slow pyrolysis for 5 hours using a 12-kg gas cylinder reactor with used oil as fuel, and 1.8 kg of acacia wood pieces (5 cm in diameter, 5 cm in length) as raw material. The results showed a charcoal yield of 38.89% (0.7 kg), which is higher than the conventional range of 25–35%. Proximate analysis, based on estimates and supporting literature, indicated a moisture content of approximately 3%, volatile matter of 18%, ash content of 4%, and fixed carbon of 75%, meeting the SNI 01-1683-1989 standard for high-quality charcoal. Stable temperature distribution during the process ensured optimal decomposition of hemicellulose, cellulose, and lignin, producing charcoal with high calorific value and low emissions. These findings confirm the potential of acacia wood as an environmentally friendly charcoal feedstock, with recommendations for further optimization of temperature in the range of 400–600 °C to enhance production efficiency and reduce reliance on unsustainable forest resources.

Abstract

A concise evaluation of Reynolds-Averaged Navier–Stokes (RANS) turbulence modeling for two-dimensional, incompressible, steady backward-facing step (BFS) flow at Re = 1000–3000 was conducted using OpenFOAM’s SimpleFoam solver with the standard k–ε model. A tri-level mesh enhancement (coarse, medium and fine) was implemented, and ambiguity was measured utilizing the Convergence Ratio (CR) and Grid Convergence Index (GCI). The fine grid (CR = 0.54; GCI = 0.0059%) was the only configuration exhibiting monotonic convergence, ensuring valid GCI estimation. Results showed reattachment length increasing from 0.11 m to 0.12 m, with stronger vortical structures and steeper shear gradients at higher Re. This study uniquely integrates RANS model validation with grid-uncertainty quantification, providing guidance for mesh optimization and reliable turbulence modeling in BFS simulations.

Abstract

Ship propulsion relies significantly on the efficiency of its components, with the shaft propeller playing a pivotal role in navigating vessels through water. Traditionally constructed from steel, this study explores an unconventional approach by employing an Aluminum Alloy base material, specifically the 6063 alloy, for the propeller shaft model. The material's mechanical properties become a crucial focus, prompting a detailed investigation into the impact of silicon and magnesium elements through a meticulous heat treatment process. The experimental procedure involves heating the Al6063 alloy to 790C, transitioning to a complete liquid state, and subsequently incorporating silicon and magnesium at specific temperatures. The stirring process, executed with a mechanical stirrer, sets the stage for the alloy's casting into a mold under pressure. Post-casting, the propeller shaft undergoes a comprehensive heat treatment regimen, including solution treatment, quenching, and artificial aging. The study's findings showcase a remarkable reduction in porosity with increasing silicon elements, reaching its lowest point at 4% wt Silicon. Tensile tests demonstrate a direct correlation between silicon addition and increased stress values, with the highest stress observed at 4% wt Silicon. Concurrently, hardness values ascend proportionally with silicon inclusion, peaking at 4% wt Silicon. The thorough analysis presented here highlights the effectiveness of silicon elements in enhancing the mechanical characteristics of the shaft propeller made of aluminum alloy, which bodes well for future developments in ship propulsion technology.

Abstract

This study examines the bidirectional relationship between economic growth and human development in Indonesia’s Papua Region, a context characterized by persistent welfare disparities despite the implementation of Special Autonomy. Utilizing a balanced panel dataset covering Papua and West Papua provinces, the research applies a dual fixed-effects panel regression model estimated via Feasible Generalized Least Squares with Panel-Corrected Standard Errors to probe the nuanced feedback connections between Gross Regional Domestic Product (GRDP) per capita and the Human Development Index (HDI). The investigation confirms a vigorous, reciprocal, and mutually augmenting association between economic advancement and human progression, where increases in per capita GRDP significantly predict improvements in HDI, and advancements in HDI in turn drive substantial elevations in regional economic output. Beyond the core economic and human development variables, electricity consumption per capita emerges as a consistent, positive catalyst in both models, functioning as a "keystone catalyst" that simultaneously supports standard of living improvements and economic productivity. Conversely, population growth is identified as exerting a drag on per capita income, highlighting a "denominator effect," where rapid demographic expansion dilutes economic gains even as it expands the potential human capital base. The findings substantiate the existence of a virtuous cycle of development in Papua but underscore that achieving inclusive welfare outcomes requires integrated policy interventions that synchronize economic productivity, human capability enhancement, and energy infrastructure expansion.
