Abstract

Pengabdian masyarakat merupakan suatu wujud gerakan dalam memberikan kontribusi kepada masyarakat agar memberikan solusi yang inovatif terhadap permasalahan yang ada di masyarakat setempat dan berguna bagi mereka. Sampah merupakan masalah yang selalu ada dalam kehidupan sehari hari baik di kota maupunn di desa. Rata-rata kota-kota besar di Indonesia menghasilkan puluhan ton sampah setiap harinya. Sampah yang dibuang di tempat sampah tanpa tindakan lebih lanjut atau ditumpuk begitu saja akan menyebabkan penumpukan dan mencemari lingkungan. Sampah digolongkan menjadi dua, yaitu sampah organik dan sampah anorganik. Sampah organik adalah sampah yang digolongkan dari bahan bahan organik seperti tumbuhan, sisa makanan, sampah buah buahan dan lain sebagainya. Umumnya masyarakat pedesaan memiliki sampah organik dari hasil perkebunan. Minimnya pengetahuan mengenai penanganan sampah organik menjadi salah satu faktor yang menyebabkan masalah ini terjadi. Oleh karena itu, diperlukan penyuluhan bagi masyarakat desa tentang alternatif pengolahan sampah organik yang ramah lingkungan dan memberikan berbagai keuntungan lainnya. Maggot merupakan larva pengurai sampah organik yang ramah lingkungan dan memberikan keuntungan berupa kasgot (bekas maggot) sebagai pupuk organik. Selain itu, larva ini juga dapat dijadikan sebagai pakan ikan yang baik karena maggot mengandung banyak lemak yang tinggi dan nutrisi lainnya yang baik bagi ikan. Penggunaan maggot sebagai pengurai sampah organik adalah salah satu alternatif yang inovatif untuk mengatasi permasahan sampah organic di desa binaan. Desa Sempajaya sendiri merupakan desa binaan yang telah dijadikan tempat untuk penyuluhan serta pengabdian dari Universitas Sumatera Utara kepada masyarakat karena masih ada beberapa hal yang perlu ditingkatkan, maka penyuluhan kembali dilakukan di desa ini.

Abstract

Air pollution is the condition of air that is contaminated by the presence of materials, substances or polluting components. One of the causes of air pollution is the combustion or inseneration process because the residue of the process can be released into the air. Based on ISPU, there are five main pollutants, namely: carbon monoxide (CO), sulfur dioxide (SO2), nitrogen oxides (NOX), surface ozone (O3), and dust particles (PM10). This study was conducted to reduce the emission of gases. The use of modified cyclone with adsorbent pipe tube from cocoa husk can increase the efficiency of combustion results with adsorption pipe tube modified cyclone. From the results of the study it was found that emissions from incineration can be controlled with APPU in the form of a cyclone. The use of cyclone alone can reduce NOX and CO levels with a reduction in NOX emissions to 53% and CO to 96%. Both emission reductions are in line with the quality standards. However, the use of adsorption pipe tubes showed better efficiency and effectiveness.

Abstract

The skin serves as a protective barrier against dust and ultraviolet (UV) radiation. Excessive UV exposure is associated with accelerated skin aging, erythema, hyperpigmentation, and carcinogenesis. This study aimed to quantify flavonoid concentrations and characterize phytochemical constituents in shallot skin extracts for their potential as active ingredients in sunscreen formulations. Shallot skin was subjected to microwave assisted extraction using 70% ethanol as the solvent. Phytochemical screening revealed the presence of flavonoids, tannins, saponins, and alkaloids in the extract. Flavonoid content was determined via UV-Vis spectrophotometry, yielding 36.33 mgQE/g. The high flavonoid concentration observed in shallot skin extract suggests its potential efficacy as an active ingredient in sunscreen formulations.

Abstract

Unsold vegetable waste from agricultural produce often rots and ends up being discarded at landfills, increasing waste volume and potentially causing environmental problems. To address this issue, vegetable waste can be processed into useful and marketable products such as bioethanol. Bioethanol is a renewable energy source obtained through the fermentation of biomass, including vegetable waste such as potatoes, tomatoes, carrots, mustard greens, and cabbage. In this community service program, an e-Bio production unit with a processing capacity of 5 liters has been designed, utilizing vegetable waste as raw material. The unit consists of pre-treatment equipment, a fermenter, and a distillation unit. The pre-treatment equipment includes an initial cooking tank, a crusher, and a pressurized tank. The fermenter tank is equipped with two manual paddle-type agitators with a diameter of 30 cm. Meanwhile, the distillation tank is made of stainless steel and equipped with a heater to heat the fermented solution and a cooling water tank to cool the evaporated e-Bio. The unit achieves a distillation efficiency of 95% with a production rate of 0.475 L/hour, producing 0.95 liters of ethanol after two hours of operation. The goal of this program is to implement the e-Bio production unit by utilizing vegetable waste as raw material, increase community or farmer income through e-Bio sales, and reduce the environmental impact caused by vegetable waste disposal.

Abstract

The increase in organic waste generation in Indonesia is driving the need for more sustainable waste management innovations, including through the bioconversion of maggots as an alternative protein source. However, at a business scale like Ratna's Black Soldier Fly (BSF), the maggot drying process remains a major obstacle because conventional methods produce inconsistent quality, require long drying times, and are energy-intensive. A community service project titled ECO-WAVE MAG was introduced to address this issue by implementing a microwave dryer as an appropriate technology. Activities included field surveys, designing and modifying the drying system, technical testing on fresh maggots with a moisture content of around 70 percent, and providing training and operational assistance to partners. Test results showed that the microwave dryer was able to reduce drying time by up to 70 percent, produce a stable final moisture content of 8–10 percent, and maintain the homogeneity and nutritional quality of the dried maggots. This technology also proved to be more energy efficient and able to increase production capacity and product shelf life.
