Abstract

Cocopeat is a binder between coconut fibers in coconut fiber. Cocopeat has high lignin and cellulose content and is resistant to bacteria and fungi. The aim of the research was to determine the mechanical characteristics of cocopeat mixtures with various dosage ratios of 20%, 40%, 60% to 80%. Mechanical characteristic testing is carried out by applying a load to specimens that have been made in accordance with ASTM D 638-03 standards. The maximum load given is 980N. The test results show that the highest stress value is found in the 40% cocopeat mixture composition, which is 8.1902 Mpa and the highest elastic modulus is found in the 20% cocopeat mixture composition, which is 13.8x10-3 Gpa, while the lowest tensile stress value is found in the 60% cocopeat mixture. and the lowest modulus of elasticity was found in a composition of 80% cocopeat mixture, namely 5.12 x 10-4 Gpa. Thus, more and more cocopeat powder is added to composite materials made from polyester resin. This causes a decrease in the value of stress and modulus of elasticity.

Abstract

This research aims to determine the main dimensions of the roll drive gear on the roll rotation speed in the roll sheeter machine. The roll rotation speed influences the quality and efficiency of the milling process to produce Ribbed Smoke Sheet. The results of the research show that the main sizes of gears on the roll sheeter machine are the gear module used is 8.34 mm, the diameter of the stitch is (150.12 mm), the inside diameter is (129.27 mm), the outside diameter is (166.80 mm), tooth height (18.76 mm), circle distance (26.18 mm), tooth width (125.10 mm), and tooth thickness (14.40 mm) and roll rotation speed on the roll sheeter machine (roll-1 =0.45 m/s), (roll-2 =0.49 m/s), (roll-3 =0.53 m/s), (roll-4 =0.57 m/s), (roll-5 =0.68 m/s), and (roll-6 =0.56 m/s).

Abstract

Pengabdian kepada masyarakat adalah salah satu Dharma dari Tri Dharma Perguruan Tinggi, disamping dharma pendidikan dan dharma penelitian, dimana Perguruan Tinggi diharapkan ada usaha secara sadar untuk mencegah terjadinya isolasi Perguruan Tinggi dari masyarakat dan lingkungannya, sehingga akan selalu ada keterkaitan atau bahkan kemanunggalan Perguruan Tinggi dan masyarakat. Dari segi letak geografis memang sangat strategis dilakukan kegiatan pelatihan pengelasan ini di desa Air sialang, karena di desa tersebut masih luas lahan pertanian yang masih aktif yang sampai sekarang ini masih digunakan. Banyak peralatan pertananian yang terbuat dari besi, contoh nya : cangkol, parang, mesin perontok dan traktor dll. Jadi peralatan yang sudah rusak tidak perlu di buat di tempat lain sehingga mengeluarkan biaya lagi. Dengan adanya kegiata ini sangat membantu masyarakat Samadua khusus nya Desa Air sialang, banyak masyarakat yang berbondong-bondong ikut melakukan pelatihan pengelasan yang dilakukan selama tiga hari. Mudah-mudahan bermanfaat bagi masyarakat, dan ilmu yang didapat bisa digunakan dan berkembang, juga bisa menciptakan usaha kecil mandiri unit desa.

Abstract

The area of coconut plantations in South Aceh Regency was 6839 Ha, out of the total number of sub-districts in South Aceh. South Kluet District was the area with the largest coconut plantation area compared to other districts, reaching 1433 Ha. Coconut coir fiber was usually used for household equipment, such as floor brooms, doormats and rope. Coconut farmers rarely process coconut husks, and after harvest, they just leave the coconut husks piled up under the coconut trees until they rot. In this research, coconut fiber waste was used as reinforcing fiber for composite materials. The aim of this research was to be determined the mechanical strength of marble waste composites mixed with resin and reinforced with coconut fiber. The composition tests carried out were: 85 : 10 : 5, 80 : 10 : 10, 90 : 7.5 : 2.5, and 80 : 12.5 : 7.5. The test carried out on each test specimen composition was a tensile test. From the results of the tests carried out on the test specimens, the maximum stress was found in the composition: (85: 10: 5) 85% Resin, 10% Marble, 5% Coconut Fiber with an average maximum stress value of 29.44827586 N /m2 and the average modulus of elasticity is 0.2415123283 N/m2.

Abstract

Global food security challenges necessitate transformative approaches to enhance agricultural productivity, particularly in highland regions facing multiple production constraints. This systematic literature review examines the potential of Internet of Things (IoT) technology integration to enhance productivity of highland vegetables (potato, cabbage, and carrot) in Aceh Tengah District, Indonesia. A critical agricultural region at 1,000-2,600 m.a.s.l. Following PRISMA guidelines, we analyzed peer-reviewed publications (2020-2025) on IoT applications in vegetable production, synthesizing evidence from successful implementations across diverse geographical contexts. Empirical evidence demonstrates that precision agriculture systems incorporating soil moisture sensors, nutrient monitoring, weather stations, and disease detection algorithms achieve productivity increases of 10-20% while reducing water consumption by 20-30% and input costs by 13%. However, IoT adoption in Indonesian highland agriculture remains below 5%, constrained by infrastructure limitations, digital literacy gaps, and economic barriers. This review identifies six critical research gaps and proposes a contextualized framework for IoT implementation adapted to smallholder farming systems in highland Indonesia. The framework addresses technological, socioeconomic, and institutional dimensions essential for sustainable digital transformation of highland agriculture. A pilot project framework is proposed targeting productivity enhancement, resource efficiency, and capacity building for sustainable implementation in Aceh Tengah's unique agroecological context
