Abstract

This study experimentally examines how integrating a convex (Fresnel) lens and a reflector affects solar cell output performance, analyzing impacts of variations in lens distance, illuminance, and associated temperature changes. Experimental methodology involved testing various lens-to-cell distance configurations under both natural sunlight and artificial lighting. Results under direct sunlight demonstrate significant enhancement: a Fresnel lens positioned at an optimal 10 cm distance achieved a peak power output of 0.939 W, a 199.04% increase compared to baseline power (0.314 W) measured without optical components. Reflector use proved beneficial by redirecting unabsorbed light onto the solar cell's active surface and promoting more uniform distribution of concentrated light. This potentially reduces severe localized temperature gradients (hot spots), even as overall cell temperature increased due to high illuminance levels from light concentration, although specific temperature correlation analysis warrants further study. However, system effectiveness was negligible under tested artificial lighting conditions, highlighting a dependency on natural sunlight characteristics. These findings underscore potential for utilizing simple, cost-effective optical components to substantially optimize solar energy harvesting, particularly for applications in environments with consistent sunlight exposure, thereby advancing sustainable renewable energy solutions.

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

Semakin berkembangnya teknologi pada dewasa ini tentunya akan banyak membawa perubahan pada kehidupan manusia dan alam. Perubahan-perubahan itu harus disikapi secara matang agar mampu membawa pengaruh positif. Teknologi yang berkembang salah satunya dalah gadget. Sepertinya gadget dapat memberikan dampak yang begitu besar pada nilai-nilai kebudayaan. Gadget dipastikan hamper dipunyai pada setiap orang. Semua kalangan baik dipastikan tidak akan terlepas dari gadget dewasa ini. Sehingga penggunaan gadget menjadi kebiasaan bahkan kebudayaan dalam suatu masyarakat sekarang ini. Meskipun demikian sebagai orang tua harus bias mengantisipasi hal-hal/ pengarush penggunaan gadget. Hal tersebut tidak hanya mendatangkan pengaruhpostif saja tetapi juga mempunya dampak negative terutapa terhadap anak-anak yang sudah sejak dini dikenalkan kepada gatged. Salah satu bentuk kerja sama yang akan dilakukan dengan Desa Tanjung Wadung adalah workshop “Pengurangan Pengaruh Negatif Gadget Pada Remaja Dan Anak”. Hasil ini diharapkan dapat menambah wawasan tentang postif dan negatifnya penggunaan gatged. Serta mampu mengurangi dampak negatifnya kepada remaja dan anak-anak.

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
