Abstract

Freshwater fish cultivation in Pulotondo Village, Ngunut District, Tulungagung Regency, East Java, has significant potential to increase income and improve the well-being of the community while fostering sustainable economic growth. Ponds managed collectively by the Village-Owned Enterprises (BUMDES) serve as a facility for freshwater fish cultivation, with an annual production of 220 tons. One of the obstacles to the development of this business is the enhancement of the value and shelf life of processed fish products. Therefore, the Community Service activity in Pulotondo Village focuses on training in the processing of freshwater fish products. Through this initiative, BUMDES and the community can enhance understanding and skills, enabling processed products to be stored longer and have a more competitive market value. To assess the training's impact, participants provided feedback through a questionnaire. The results indicate that the training activities were well-understood by the participants, showing an indication of increased entrepreneurial spirit through local potential.

Abstract

The oxidation of carbon monoxide (CO) and unburnt hydrocarbons (HC) under segmented honeycomb catalysts was investigated using actual exhaust gas mixtures from a gasoline-fueled internal combustion engine of a motorcycle. The honeycomb catalysts were prepared through a wet process, resulting in four types coated with transition metals (Cu, Cr, Fe, and Ni) supported on Al2O3. The oxidation of CO and HC was monitored using an exhaust gas analyzer across a range of air-to-fuel ratios (AFR), from lean to rich, under stationary conditions. The results demonstrate that the honeycomb catalysts effectively decreased CO and HC concentrations in the exhaust gas. Among the transition metal oxide honeycomb catalysts, Cr and Ni exhibited high CO and HC conversion rates, surpassing those observed with Cu. The average CO and HC conversion calculations, spanning from lean to rich air-to-fuel ratios, were consistent with the actual conversion rates achieved. Furthermore, the study investigated the effect of honeycomb segmentation on CO and HC conversion. Surprisingly, the catalytic performance of Cr and Ni remained high even with longer gaps in the honeycomb. Interestingly, the conversion of CO and HC over the iron oxide honeycomb catalyst increased as the gap in the honeycomb became longer. This is likely due to an increase in the gap size and enhanced re-mixing of reactants (CO, HC, and O2) caused by recirculation. Thus, this study provides valuable elucidation on the potential application of segmented honeycomb catalysts for reducing CO and HC emissions in exhaust gases.

Abstract

Lubricating oil is a type of fluid needed by a machine to carry out work steps. Significant changes in the temperature of the lubricating oil viscosity until it is too low makes the engine components less lubricated, which causes the engine components to heat up quickly because the friction between the metals that occurs becomes greater. Lubricant that is of poor quality can cause deposits to appear in the engine room which results in the engine working harder. The aim can be achieved in this research by varying the lubricating oil with a mixture of Estolide and Diglyceride surfactant percentages of (2.5%, 5% and 7.5%). This test was carried out on a petrol motorbike with a combustion chamber volume of 125cc with standard conditions. The data that will be taken in this research includes engine temperature and power. The power testing method using a dynamometer and lubricant with cooking oil mixed with 7.5% estolide surfactant after heating produces an average value of 6.52 HP which has a higher average value than oil with a value of 5.37 HP

Abstract

The development of the automotive world to date has grown rapidly, especially two-wheeled vehicles. Large temperature changes in lubricating oil viscosity, even if the value is too low, will reduce the lubrication of engine parts, increase friction between metals, and cause engine parts to heat up quickly. Efforts to control and overcome excessive engine heat can replace mineral-based lubricating oils with environmentally friendly and biodegradable lubricating oils. The purpose of this study is to determine the effect of using a mixture of cooking oil and surfactants C64H124O26 and C42H80NO8P as engine lubricants on the power and temperature produced by motorized vehicles. The independent variables of this research are RPM variation and mixture of pure cooking oil with lecithin and polysorbate surfactant (2.5%, 5%, 7.5%). The dependent variables are engine temperature and power. The control variables of this research are testing at room temperature, 4 stroke 125CC matic vehicle, and Raw Material using Palm cooking oil. The test method uses an infrared thermo gun for temperature and Dyno test for the highest power test on the type of Cooking Oil + Polyosrbate 7.5% with an average overall power of 5.872, then for the lowest temperature on the type of Cooking Oil + Polysorbate 2.5% with an average value of 86.2ºC.

Abstract

Nickel oxide (NiO) is a material used due to its remarkable chemical stability, magnetic properties, and electrical characteristics molecules. One notable feature of NiO is its unreactive surface with water (H2O), making it an ideal candidate for use as a cathode in the electrolysis process to produce hydrogen (H2) gas. During electrolyte process, H2 is produced through the oxidation reaction at the anode and the reduction reaction at the cathode. Despite its potential, the detailed mechanism of H2O molecule decomposition using a NiO electrode remains inadequately explained. This research aims to elucidate the increased energy arising from the attractive forces between NiO and H2O molecules. To investigate these attractive forces, simulations were conducted to understand the chemical characteristics of the molecules, including bond lengths, bond angles, and their properties. The results indicated that the use of NiO electrode could increase the potential and kinetic energy of H2O molecules. This energy increase is attributed to the formation of specific polar and non-polar bonds. Specifically, polar bonds were formed between (1) the nickel (Ni) atom in NiO molecules and the oxygen (O) atom in the H2O molecules and (2) the O atom in NiO molecules and the H atom in the H2O molecules. Non-polar bonds were formed between (1) the H atom in the H2O molecules and the Ni atom in NiO molecules, and (2) the O atom in NiO molecules and the O atom in H2O molecules. This study highlights how these interactions help in the electrolysis process by enabling the efficient breakdown of water molecules and the production of hydrogen gas

Abstract

The Community Service (CS) project was implemented in Sumberingin Kidul Village, Ngunut District, Tulungagung Regency, East Java. The target beneficiary was UD. Arta Lumintu, a local SME engaged in beef cattle farming. The farm, established in 2017, was temporarily closed due to the Covid pandemic and resumed operation after a year. Key challenges included high temperatures (24-31°C) and humidity (74-77%), which negatively impacted cattle productivity and excessive electricity consumption for cattle shed operations. The project aimed to address these issues by installing a water spray system with a high-pressure pump and an off-grid solar power system. The system effectively reduces temperature and humidity in the sheds while minimizing electricity costs. The installation consists of a 540 Wp solar panel, a 1500 VA Smart inverter, a 100 Ah VRLA battery, and six pressurized water sprinkler points positioned in various areas of the cattle sheds, powered by a 350 W booster pump. This initiative improves farm efficiency, supports energy independence, and introduces smart farming technology to benefit local farmers.

Abstract

The problem of household waste, which accounts for 50-70% of the total waste in Indonesia, mainly in the form of organic waste such as food and vegetable scraps, is a major challenge in environmental management. Composting is an effective method of managing organic waste by turning it into compost. However, organic waste management in Indonesia is still minimally practiced because it is considered to have no economic value. A 50 kg capacity composter machine equipped with a vertical mixer and using an electric motor can increase composting efficiency. This study aims to analyze the feasibility of composter machines and to analyze the effect of speed and mixing time on composter machines on the homogeneity of organic waste. The research method used is quantitative experimental with factorial experimental design (DOE) to analyze the effect of speed and stirring time on the composter machine on the homogeneity of organic waste. The stirring speed variations tested were 30, 45, and 60 RPM, with mixing times of 20, 30, and 40 minutes. The results showed that the single mixer composter machine proved to be feasible and reliable in producing homogeneous organic waste, with a high process capability value of 5.86. The use of mixing speed from 30 RPM to 60 RPM and mixing time from 20 minutes to 40 minutes significantly increased the homogeneity of organic waste, with the highest value of 97.54% at 60 RPM speed for 40 minutes.

Abstract

Waste is an unavoidable problem along with increasing population activity due to population growth, which causes the amount of waste to increase, especially from traditional markets, tourist areas, dense settlements, and public facilities. In Malang City, waste in 2023 is estimated to reach 778.34 tons, so proper and environmentally friendly management is needed, one of which is by processing organic waste into a homogeneous compost mixture using a mixing machine. This study aims to analyze the effect of double mixer speed and mixer time on the mixing machine on the homogeneity of organic waste in the composting process. The research method used is quantitative experimental with factorial experimental design (DOE) for the effect of double mixer speed and mixer time on the homogeneity of organic waste in the composting process. The double mixer speed variations tested were 20, 45, and 60 RPM, with mixing times of 20, 30, and 40 minutes. The results showed that the double mixer speed and stirring time had a significant effect on the homogeneity of organic waste in the composting process, with an optimal increase in homogeneity occurring at a speed of 60 RPM and a duration of 40 minutes. Higher speeds accelerate particle distribution, while sufficient mixing time ensures even distribution, thereby increasing the efficiency of microbial decomposition.
