Abstract

This research aims to determine the performance of the Diesel Particulate Filter (DPF) in reducing exhaust gas opacity, smoke temperature and noise levels on the 1997 Isuzu Panther. The DPF used in this research is made of copper and stainless steel with a metallic honeycomb model. This experimental study involved installing a DPF on a standard diesel vehicle exhaust system and measuring exhaust emissions, smoke temperature and noise levels. The measuring instrument used to test the opacity and temperature of the exhaust gas is a smoke opacity meter based on the SAE-J1667 test procedure (snap acceleration test procedure). Meanwhile, to test the noise level, a sound level meter based on ISO/FDIS 5130:2006 (E) standard was used. Tests were carried out under various conditions including standard exhaust testing (Non-DPF), standard exhaust with DPF (DPF), DPF with 50 gram stainless steel material (DPF + SS50), DPF with 100 gram stainless steel material (DPF + SS100), and DPF made of 150 gram stainless steel (DPF + SS150). The test results showed that DPF had a significant effect on reducing exhaust opacity, smoke temperature and noise level of the 1997 Isuzu Panther. The greatest reduction in exhaust opacity, smoke temperature and noise level were produced by DPF + 150 gram stainless steel with exhaust opacity that could be reduced by 87, 1 ± 1.1%, smoke temperature of 43.2 ± 1.7%, and noise level of 15.2 ± 1.3%. These findings open up opportunities for the development of DPF technology that is more efficient in reducing diesel vehicle emissions, contribute to stricter emissions regulations, and support filter design innovation to improve air quality and reduce the negative impact of vehicles on the environment. In addition, the results of this research show that the use of DPF is in accordance with the diesel vehicle emission threshold regulations set in Indonesia.

Abstract

Landslides occur as a result of a geological process caused by the displacement of rock or soil masses. In general, landslides are caused by shifting soil and excessive water content due to high rainfall. One of the processes that occur in rivers is sedimentation With the entry of sediment into the river flow, it will result in increased river surface flow and deposition which causes siltation of the river. This siltation will greatly affect the capacity of the river when the rainy season arrives, because it can cause floods. For this reason, assistance and training are needed to increase community knowledge about the use of Internet of Things (IoT) based monitoring system tools around the Kahayan river basin. IoT is a technology that allows smart objects, things, and machines to be connected via the internet so that data can be received in real time. The people of Pahandut Village were enthusiastic in participating in the socialization activities provided and felt the benefits of increasing knowledge starting from an understanding of the Internet of Things and the use of monitoring system tools for land shifts. Based on the evaluation results, it is known that participants have increased knowledge and insight into the Internet of things and its application in this case the soil shift monitoring system tool which will later be installed in residential areas around the watershed.

Abstract:The Consumption of fruit and vegetables by the community is inseparable fromthe waste generated. Conventionally, fruit and vegetable waste is thrown away, or forpeople who have livestock or livestock, the waste is used for feed. This is of course veryunfortunate, given the fact that optimal fruits and vegetables can be utilized. Utilizationof organic waste as animal feed ingredients as conventional compost material. If organicwaste is made into compost, the benefits are only given to plants. It is different if organicwaste is made into animal feed, which is beneficial for livestock, and from livestockobtained from livestock manure which can be made compost. However, organic wasteused for animal feed, easy to rot and voluminous (large) processing techniques areneeded to improve the future of storage, facilitate storage, and to enhance the antinutritionaleffects that usually contain alkaloids.Keywords: Waste, Fruit vegetable, Processing techniqueAbstrak:Konsumsi buah dan sayur oleh masyarakat tidak lepas dari adaya limbah yangdihasilkan. Secara konvensional, limbah buah dan sayur dibuang begitu saja, atau bagimasyarakat yang memiliki hewan ternak atau peliharaan, limbah tersebut dijadikanpakan. Hal ini tentu saja sangat disayangkan, mengingat sebenarnya limbah buah dansayur tersebut masih dapat dimanfaatkan secara optimal. Pemanfaatan limbah organiksebagai bahan pakan ternak ataupun sebagai kompos secara konvensional dinilaimemiliki kelemahan. Jika limbah organik dijadikan kompos, manfaatnya hanya diberikankepada tanaman. Berbeda jika limbah organik dijadikan pakan ternak, yang bermanfaatbagi ternak, dan dari ternak diperoleh kotoran ternak yang dapat dijadikan kompos.Namun, limbah organik yang dijadikan pakan ternak secara langsung, bersifat mudahmembusuk dan voluminus (bulky) sehingga diperlukan inovasi teknik pengolahan limbahuntuk memperpanjang masa simpannya, mempermudah penyimpanan, dan mengurangiefek anti nutrisi yang biasanya berupa suatu alkaloid.Kata Kunci : Limbah, Buah sayur, Teknik pengolahan

Abstract

The lack of technical knowledge regarding klotok engine maintenance among fishermen in the Kahayan River Basin results in a high risk of operational damage. This Community Service Program aims to improve fishermen's skills through theoretical and practical training in klotok engine repair. The program's main advantage lies in its sociocultural approach to correcting technical misconceptions, namely by aligning academic terms with local terminology that is easily understood by the local community. The results of an evaluation of 11 participants showed that this approach effectively increased participant knowledge with an N-Gain of 0.405 and achieved a satisfaction level of 87.27%. The practical implication of this finding is the recommendation to develop a machine maintenance guide module that adopts local language and terms as a self-learning reference for fishermen.

Abstract

This article addresses the growing demand for fish products in Indonesia, driven by increased per capita fish consumption, which has risen from 43.88 to 54.49 kg annually. This surge has led to an expansion of fish farming activities, particularly within small-scale enterprises. However, a significant challenge faced by these farmers is the high cost of commercial fish feed, which accounts for 60-80% of total production expenses. These costs are further amplified by the reliance on expensive and environmentally harmful imported ingredients such as fishmeal and soybean meal. In response to these challenges, this study focuses on a community service initiative conducted at KUPS Fisheries in Tanjung Sangalang, Pulang Pisau, Central Kalimantan. The project aimed to provide local fish farmers with essential skills in feed production and the utilization of floating net cages for sustainable fish farming. Through training and hands-on practice, participants were introduced to cost-effective, locally sourced alternatives for fish feed, reducing dependency on expensive imports. The initiative also promoted environmentally friendly practices, contributing to both the economic and ecological sustainability of small-scale fish farming in the region.
