Abstract

This study aims to this study was to examine the effect of polypropylene (PP) plastic and activated carbon (AC) composition in a plastic composite material. The composite material was mixed using an internal mixer at a processing temperature of 220°C and a speed of 50 rpm. The mixture was then molded with dimensions of 100 mm in length, 15 mm in width, and 2,5 mm in thickness. The sample molding was performed using a compression molding method with a pressure of 1500 MPa at 250°C and a holding time of 300 minutes. Subsequently, the samples were cut according to the bending test dimensions following ASTM D790-03 standards, with dimensions of 100 mm x 12.7 mm x 2.5 mm. The test results for the polypropylene-activated carbon composite in the first composition showed a maximum stress point of 36.95 MPa and an elastic modulus of 4.3096 MPa, while the second composition showed a maximum stress point of 34.58 MPa and an elastic modulus of 3.371 MPa. These findings indicate that increasing the activated carbon composition in polypropylene polymer results in a reduction in bending strength.

Abstract

In general, every livestock needs feed in the form of a mixture of livestock feed. The livestock feed fermentation process is currently phenomenal because it provides benefits that are felt by farmers. Maybe many people know the fermentation as a process of making supplement drinks only. It turns out not, the fermentation process can be used as an alternative to making high-quality livestock feed. In addition to being very simple to make, making feed by fermentation also saves time and money, because farmers are no longer busy with herding or grazing. This horizontal mixer machine has a capacity of 100 kg / Batch. In making this machine includes manufacturing processes such as: welding, grinding, drilling, bending, cutting torch or gas cutting, and non-permanent joints, namely nut and bolt joints. The components of the machine are: frame, tube, double screw, axle shaft, bossing, gear box, housing bearing, block bearing, pulley, v-belt, and electric motor. And then assembled and put together into a machine. From the above explanation, the following conclusions can be drawn: 1. Horizontal mixer machine with a tube diameter of 60 cm and a width of 90 cm, is capable of mixing 100 kg/batch of animal feed. 2. Horizontal mixer machine using a double screw produces a more homogeneous mixture compared to using the manual method.

Abstract

This community service activity aims to address ecosystem damage, coastal erosion, climate change, reduced fish catch, declining water quality, loss of biodiversity, and environmental pollution, as well as support coastal community welfare. able to provide a positive stimulus to the community about the importance of mangrove forests in coastal areas, which impacts the socio-economic conditions of the Regemuk village community. The activity was carried out by applying science and technology directly to strengthen mangrove plants. The results obtained from the activity are that this community service can provide a positive stimulus to the community about the importance of mangrove forests in coastal areas, which impacts the socio-economic conditions of the Regemuk village community, and the planting of mangroves in coastal areas will maintain ecological functions such as providing habitat for marine animals to shelter, food chains, and breeding, as well as protecting Pantai Labu from sea water abrasion.

Abstract

This Community Service activity was carried out at the Roti Pakcik Tanjung Morawa MSME through work process observations, discussions with the owner and workers, and recording the condition of the production facility. The activity focused on two fundamental needs of the MSME: improving the layout of the work area to enhance production efficiency and identifying the need for relevant production technology. The observation results showed a crowded work area, unclear functional zoning, and the movement of materials and products across the same area. These conditions increased waiting times, increased the risk of cross-contamination, and complicated quality control. In addition, the production process still relied on manual practices and limited tools, so there was a need for technology in the form of a flour sifting machine to maintain ingredient consistency, a mixer to maintain dough homogeneity according to production capacity, and a bread cutting machine to speed up the process, improve size uniformity, and reduce work fatigue. The activity resulted in a workflow problem map, an initial zoning design, and a list of technology priorities as a basis for further mentoring. These findings position the program as the initial stage of a realistic and field-based MSME production transformation.

Abstract

Perkembangan teknologi menuntut lembaga pesantren untuk adaptif dalam mentransformasikan metode pembelajaran konvensional ke arah digital. Pesantren Modern Ta'dib Al-Syakirin di Kecamatan Medan Johor memiliki potensi infrastruktur yang baik, namun pemanfaatan perangkat digital oleh para santri masih terbatas untuk aktivitas hiburan dan belum dioptimalkan untuk mendukung pembelajaran agama. Kegiatan Pengabdian kepada Masyarakat (PKM) ini bertujuan untuk meningkatkan pemahaman dan keterampilan praktis santri dalam memanfaatkan media pembelajaran digital sebagai sarana penguatan keilmuan agama dan dakwah kreatif. Metode pelaksanaan yang digunakan adalah Experiential Learning yang meliputi tahapan analisis situasi, persiapan instrumen, pelaksanaan pelatihan intensif berbasis praktik langsung (hands-on), serta evaluasi melalui pre-test dan post-test. Peserta kegiatan ini adalah 50 santri pesantren tersebut. Hasil evaluasi menunjukkan adanya peningkatan signifikan pada aspek pemahaman dan keterampilan teknis peserta sebesar 85% berdasarkan hasil analisis skor post-test. Selain itu, para santri berhasil memproduksi ragam media pembelajaran digital berbasis keagamaan yang interaktif secara mandiri. Kegiatan ini berimplikasi pada kesiapan santri dalam menghadapi tantangan era digital serta mempercepat akselerasi digitalisasi ekosistem pendidikan di lingkungan pesantren.

Abstract

This study aims to analyze the performance of a fried onion draining machine designed for the needs of small-scale food industries. The machine operates using the principle of centrifugal force and is constructed with 304 stainless steel to ensure food safety and resistance to corrosion. Testing was conducted using variables such as rotation speed, draining time, and material capacity. Results show that the machine can reduce oil content in fried onions by 14.29% within 2 minutes, with a draining capacity of 50 kg per hour at 700 rpm. Energy efficiency achived was 35,49%, showing the potential for practical application of this machine in the UMKM environment. The use of this machine results in fried onions that are crispier, have a longer shelf life, and are processed more hygienically and efficiently. Further recommendations include design and operation system optimization to improve performance.

Abstract

This study investigates the effect of using Liquefied Petroleum Gas (LPG) as an alternative fuel to Pertalite on the performance, energy efficiency, and operating cost of a 6.5 HP gasoline engine-driven water pump. Experiments were conducted at three engine operating conditions: minimum, average, and maximum engine speeds. The evaluated parameters included engine speed, water discharge, hydraulic power, shaft power, brake specific fuel consumption (BSFC), thermal efficiency, overall system efficiency, and fuel operating costs. The results indicate that the pump's hydraulic performance, as measured by water discharge and hydraulic power, is not significantly affected by the type of fuel used. However, engines that use Pertalite tend to have slightly better thermal and system efficiencies than LPG engines. From an economic perspective, LPG offers a substantial advantage, with lower operating and energy costs per unit of power. Therefore, despite Pertalite's slightly superior technical efficiency, LPG is a more economical alternative fuel for long-duration water pump applications.
