Abstract

The Coordinating Minister for Maritime Affairs believes that Indonesia is experiencing an increase in exports, particularly in the fisheries sector. This is very important because Indonesian waters consist of 44.7% fish, and fisheries are one of Indonesia's key commodity advantages. However, abundant natural resources alone do not guarantee that a nation will become superior if not accompanied by good human resources as well. The issue of fish drying is a crucial problem in the fish processing sector, including for UKM Jaya Utama in Probolinggo City. UKM Jaya Utama still uses traditional drying methods, relying on sunlight as the main drying tool. As a result, UKM Jaya Utama faces drying challenges during the rainy season. The cartridge heater-based fish dryer machine is a machine specially designed for drying and preservation, offering an alternative solution for fish drying during the rainy season and extending the shelf life of the fish. The research method used was an R&D approach with mackerel fish as the research sample, with a capacity of 10 to 15 kg per drying cycle. The machine trial results showed improved work efficiency by reducing the drying duration from 6 hours without the machine to just 2 hours, with potential profit increases of up to 3.6 times.

Abstract

The Quester CWE 370 truck is one of the most widely used transport vehicles in the industry, where reliability and operational efficiency are critical to ensuring a smooth supply chain. This research aims to optimize truck performance through vessel system modification, which focuses on improving fuel strength and efficiency. The modification process includes checking the raw material, cutting, welding, and smoothing, which is followed by testing to ensure fuel flow stability and better engine response. The results show that vessel system modifications not only improve fuel efficiency, but also extend engine life and reduce the need for routine maintenance. Thus, these modifications provide long-term benefits for the company in terms of operational cost savings and increased productivity.

Abstract

Program pengabdian ini bertujuan memberdayakan masyarakat dalam pengelolaan sampah melalui edukasi dan penerapan Teknologi Tepat Guna (TTG) berupa alat pengepress botol plastik. Kegiatan dilaksanakan di Bank Sampah Semangka 8, Desa Tambakasri, pada 19 Juli 2025 dengan 40 peserta. Metode meliputi penyuluhan partisipatif, demonstrasi TTG, pelatihan teknis, dan advokasi keberlanjutan. Evaluasi dilakukan melalui pre-test dan post-test, yang menunjukkan peningkatan pemahaman signifikan, seperti pemahaman 3R dari 45% menjadi 92%. Sebanyak 90% peserta tertarik mempraktikkan pengelolaan sampah mandiri, dan alat TTG terbukti mampu mengurangi volume botol hingga 80%. Program ini mendorong inisiatif lanjutan seperti komposting dan daur ulang kreatif, serta mendukung pencapaian SDGs 11, 12, dan 13 melalui teknologi sederhana, edukasi efektif, dan kolaborasi warga.

Abstract

Lonjakan permintaan jamu terkendala perajangan herbal UMKM yang lambat dan tidak seragam, sehingga ekstraksi kurang optimal dan kualitas tidak konsisten. Kegiatan pengabdian masyarakat ini bertujuan meningkatkan efisiensi dan kapasitas produksi UMKM Hanacaraka Herb di Kota Malang melalui penerapan mesin perajang rempah otomatis berbasis motor listrik. Dimana, proses perajangan manual yang lambat, membutuhkan banyak tenaga kerja, dan menghasilkan potongan tidak seragam. Metode pelaksanaan meliputi observasi lapangan, perancangan dan pembuatan mesin Teknologi Tepat Guna (TTG), pelatihan penggunaan, serta pendampingan di lokasi mitra. Mesin yang dihasilkan memiliki kapasitas ±100 kg/jam dengan hasil rajangan seragam dan higienis. Hasil penerapan menunjukkan peningkatan kapasitas produksi hampir lima kali lipat, pengurangan waktu produksi 75%, serta peningkatan keseragaman dan higienitas produk. Secara kualitatif, mesin ini memperbaiki konsistensi rasa dan warna jamu, menguatkan citra merek, meningkatkan efisiensi tenaga kerja, dan membuka peluang perluasan pasar.

Abstract

Corrosion still remains a serious problem in the application of aluminum alloys, such as Aluminum 6061, which is one of the most widely used aluminum alloys in industries because of its high strength-to-weight ratio. However, the material degrades when exposed to aggressive environments, such as acidic, alkaline, or salty solutions, and the control of corrosion has been achieved with the use of synthetic chemical inhibitors, but the increasing concern of environmental and health risks has shifted attention to more eco-friendly alternatives. The present study aimed at evaluating the efficacy of three vegetable oils (coconut oil, palm oil, and soybean oil) as environmentally friendly corrosion inhibitors for Aluminum 6061, and the alloy coupons were subjected to three different corrosive solutions (hydrochloric acid, sodium hydroxide, and sodium chloride). A quantitative experimental procedure was employed to determine the corrosion rate through the measurement of the weight loss of aluminum coupons prior to and after the immersion, and the results showed that all three oils were able to reduce the corrosion rate when compared to the samples without any inhibitor. Among them, coconut oil gave the best protection, followed by soybean oil and palm oil, because the adsorption of the organic compounds and fatty acids in the oils onto the aluminum surface formed a thin layer that separated the metal and the corrosive environment. Consequently, the results also showed that the use of bio-based oils can be a promising alternative to synthetic corrosion inhibitors in industries that use aluminumbased materials.

Abstract

This study aims to explore the potential of castor oil (Jatropha curcas L.) as a plant-based alternative engine lubricant and compare it to commercial mineral-based lubricants. The research process includes drying Jatropha seeds and epoxidizing the oil using oxidizing agents (H₂O₂) and (CH₃COOH) with variations of (1:0.075; 1:0.15; 1:0.225; and 1:0.30). Chemical testing was conducted to analyze the acid number of the oil, while physical testing was carried out to measure its viscosity index, flash point, and pour point. The results show that Jatropha oil has an acid number of 5.30, a viscosity index of 217, a flash point of 270°C, and a pour point of 0°C. Therefore, Jatropha oil demonstrates potential as a base material for engine lubricants due to its relatively high flash point, which approaches that of polyol ester (POE)-based oils. However, further modification with additives is required to lower its pour point, ensuring it remains fluid in colder climates such as those in subtropical regions.
