Abstract

Teknologi 3D printing merupakan sebuah alat percetakan modern yang sudah berkembang dalam dunia manufacturing. Dalam penelitian ini, dilakukan inovasi dengan menggunakan filamen yang terdiri dari PLA dan kuningan. Penentuan kombinasi parameter 3D printing menjadi kunci untuk mencapai kekuatan bending paling optimal pada hasil cetakan. Parameter yang diatur meliputi suhu nozzle temperature, print speed, dan layer height. Penelitian ini menggunakan metode Taguchi L4(23), serta pengolahan data menggunakan ANOVA. Kombinasi parameter optimal pada penelitian ini menggunakan suhu nozzle temperature 240 ⁰C, layer height 0,2 mm dan print speed 20 mm/s dengan nilai kekuatan bending sebesar 8.72MPa dan terendah 2.66 MPa. Faktor yang berkontribusi terhadap nilai bending adalah nozzle temperature dan layer height dengan kontribusi sebesar 45.29 % dan 20.91 % keduanya memiliki pengaruh yang signifikan. Kontribusi print speed sebesar 9.09 % tidak signifikan.

Abstract

Panduman Village, Jelbuk Jember District, is a fostered village by the University of Jember. Sumbercandik is one of the hamlets in Panduman Village with a geography of mountain slopes and hills and at an altitude that is very supportive for coffee farming/plantations. It is no wonder that the best coffee products are produced from this village. Ironically, the lives of many coffee farmers still fall into the pre-prosperous group. One of the reasons is that farmers sell coffee logs or wet-skinned coffee at relatively low prices. At the same time, factory-made chemical fertilizers have skyrocketed in price, and availability is strict. Various efforts have been made by the local government and other service teams related to these coffee farmers, but they have not touched those in Sumbercandik Hamlet. This community service seeks to uplift the economy of Panduman Village, especially the coffee farmers of Sumbercandik Hamlet, with the introduction of post-harvest coffee technology, utilization of coffee waste for fertilizer and briquettes, and management and cooperatives. This grant ceiling will carry out the proposal in three years. The first year was with the introduction of post-harvest technology in the form of wet and dry skin stripping (horn skin). In the second year, intensive drying techniques using technical and thermal methods. In addition, farmer group formation and simple production management. Year three, post-harvest waste processing technology. The first year's focus was on providing a coffee skin peeling machine. Each year will involve different lecturers with agricultural, management and cultural competencies. This activity is in line with the 2021-2025 RIPP of the University of Jember with the featured topic "Development of people's coffee towards an organic system to improve community welfare".

Abstract

This paper presents a community engagement initiative in Kuwon Village, Magetan Regency, aimed at enhancing agricultural productivity through compost production mechanization. The project, a collaboration between university researchers and local farmers, introduced organic composting techniques using a specially designed compost chopper machine. The initiative sought to address the challenges of high fertilizer costs and limited subsidized fertilizers, promoting sustainable agricultural practices and improving farmers' livelihoods. The primary goal was to provide an efficient, cost-effective method for producing organic compost, reducing dependency on chemical fertilizers, and improving soil health. The project followed a participatory approach, involving farmers at every stage—from needs assessment to design, fabrication, training, and implementation—ensuring solutions suited to the local community's needs. The compost chopper machine reduced time and labor in compost production, and farmers reported improved soil health and higher crop yields. The project also fostered community collaboration as farmers worked together to adopt new practices. Economic benefits included lower input costs and increased income from higher productivity. The success of this initiative highlights the potential of combining technological innovation with community involvement to tackle challenges faced by rural farmers in Indonesia, promoting sustainable agricultural development and improving livelihoods.

Abstract

Used cooking oil is a waste product with great potential as a raw material for biodiesel production through transesterification. This study was conducted to determine the effect of transesterification reaction temperature on biodiesel yield and quality. The biodiesel production process includes a degumming step to remove gums by adding 1% H₃PO₄. This is then followed by transesterification using 1% NaOH as the catalyst, an oil-to-methanol ratio of 1:0.5, a stirring speed of 300 rpm, and a reaction time of 60 minutes. The transesterification reaction temperatures were 40°C, 50°C, 60°C, and 70°C. The results showed that the reaction temperature significantly affected the yield and physical quality of biodiesel. The highest yield was 85.85% at 40°C, while the lowest was 80.37% at 70°C. The maximum viscosity was observed at 60°C (6.0 cSt), and the minimum at 70°C (5.71 cSt). The highest density was 0.8620 g/mL at 50 °C, and the lowest was 0.8607 g/mL at 40 °C. The highest flash point was 40°C at 173.27°C, and the lowest was 70°C at 164.97°C. The results showed that the biodiesel produced met the quality standards of SNI 7182:2015, thus supporting its suitability as an alternative fuel derived from used cooking oil.

Abstract

Waste management remains a critical challenge in rural and semi-urban communities in Indonesia, where limited infrastructure and low public awareness often lead to environmental degradation. Jelbuk Village in Jember Regency produces approximately 1,200 kg of household waste per day, most of which is disposed of in rivers or vacant land. This condition has resulted in pollution, health risks, and flooding, while the economic potential of waste recycling remains untapped. To address these issues, the Universitas Jember community service team implemented an integrated waste management program that combines technical innovation with community empowerment. The technical approach involved designing and fabricating a portable organic waste chopper machine with a capacity of 120 kg/hour, enabling the production of compost from organic waste. In parallel, inorganic waste such as plastics and metals was separated for recycling. The non-technical approach included training, awareness campaigns, and mentoring in simple bookkeeping to strengthen community capacity for sustainable waste management. The program successfully reduced waste accumulation, improved sanitation, and created new economic opportunities through compost production and the sale of recyclable materials. Furthermore, the involvement of students in design and implementation enhanced academic outcomes and knowledge transfer. This initiative demonstrates that integrated technical and social approaches can effectively transform waste problems into community-based solutions with long-term sustainability.

Abstract

Pembuatan pipa cetak granul pada mesin granulator double roller memerlukan proses pengeboran dengan presisi tinggi. Pergeseran mata bor pada permukaan pipa silindris sering menurunkan kualitas lubang dan meningkatkan waktu pengerjaan. Penelitian ini bertujuan merancang dan menguji performa drilling jig untuk meningkatkan kualitas dan efisiensi pengeboran. Metode penelitian meliputi perancangan alat, analisis kekuatan mekanik, simulasi struktur menggunakan Finite Element Analysis, dan pengujian performa. Hasil perhitungan menunjukkan tegangan kerja pada pipa, fixture, dan bushing masing-masing sebesar 1,66 MPa, 4,40 MPa, dan 1,56 MPa, masih berada di bawah batas tegangan izin. Hasil simulasi menunjukkan nilai von Mises stress sebesar 4,613 MPa, displacement sebesar 0,002197 mm, dan safety factor sebesar 15. Penggunaan drilling jig mengurangi waktu pengeboran dari 695 detik menjadi 182 detik serta meningkatkan kualitas lubang dan permukaan pipa. Pipa cetak yang dihasilkan mampu menghasilkan granul berdiameter 3 mm sesuai standart pupuk organik.
