Abstract

The partner in this PKM is Paloh Punti Village, Muara Satu, Lhokseumawe City. Paloh Punti Village is one of the villages in the Unimal Campus area which is 3 km from the Bukit Indah Campus. In general, the jobs of the people in Paloh Punti village are farmers and livestock breeders. Almost 80% of plantation land in this village is planted with coconut trees. Selling coconut plantation products is one of the main sources of income for the people of Paloh Punti village. So far, the selling value of coconuts in the Paloh Punti area is relatively low, ranging from 1,800 to 2,000 rupiah. This low selling value is due to the coconut plantation owners selling their produce intact, known in the community as round coconuts. To increase the selling value of these coconuts, the Community Service is trying to offer assistance in making a Coconut Skin Peeling Machine which will later be donated to the Paloh Punti Village Community under the coordination of the Village Leadership. This service will be carried out in stages, starting with counseling, introduction to peeling tools/machines, testing the tools, evaluating the economic value and handing over the coconut peeling machine to the village leadership. Counseling and training on the use of this tool begins with designing a tool using the ATM method (Observe, Imitate and Modify) from pre-existing types of equipment and adapt it to the needs of supporting machines.

Abstract

The process of harvesting stingless bee honey requires special tools, the use of vacuum pumps as a harvesting medium makes it easier for farmers, saves time, and maintains honey quality. The purpose of this service is to provide training to the community on how to use a honey harvesting tool with a vacuum pump with a capacity of 7 liters/minute, the assembly process and maintenance. From the results of the service that has been carried out for beekeepers in Pulo Meria Village, it is found that the honey suction tool from the Vacuum pump is very useful for farmers, easy to use, production capacity of 1 liter per hour and portable. The difference in the amount of capacity is due to the different honey harvesting process due to having different sized honey bags and different honeycomb contours. From the empowerment of the honey farming community, it was found that 89% of the farmers got better quality honey harvests and increased honey production by 57% more.

Abstract

Struktur Beton merupakan salah satu mata kuliah yang memerlukan usaha ekstra. Hal ini disimpulkan berdasarkan hasil observasi dan wawancara yang dilakukan kepada 15 orang mahasiswa S1 PTB FT UNP. Berdasarkan hasil wawancara yang dilakukan pada 25 September 2023, sebagian besar dari mereka mengatakan adanya kendala terkait kelebihan dan kekurangan untuk setiap mahasiswa berdasarkan perbedaan latar belakang pengetahuan. Dari segi kelebihan, sebagian mahasiswa memiliki pengetahuan matematika dan fisika yang lebih kuat serta kemapuan berfikir logis yang baik, namun kekurangannya mereka kurang familiar dengan konsep teknik sipil, serta hal ini berakibat kepada sulitnya mahasiswa memahami konsep abstrak untuk menerapkannya kepada visualisasi gambar dengan tepat. Tujuan utamanya adalah agar materi perkuliahan dapat disampaikan dengan cara yang lebih engas dan sesuai dengan konteks perkembangan terkini dalam bidang ini. Metode penelitian yang digunakan adalah MDLC (Multimedia Development Life Cycle), dengan pengumpulan data melaluiI kuesioner. Data yang diperoleh kemudian dianalisis menggunakan uji validitas, analisis deskriptif. Hasil analisis menunjukan bahwa teknologi Augmented Reality mempengaruhi kemampuan memahami materi struktur beton pada mahasiswa yang mengampu mata kuliah struktur beton.

Abstract

Lathe machining is one type of conventional machine tool used for cutting/filling workpieces which is done by making an incision on the workpiece where the tool is moved translationally and parallel to the axis of the rotating workpiece. The result of the components of the turning process that is commonly done is surface roughness which is influenced by tool cutting angle, feeding speed, cutting speed, depth of cut. This study was conducted to determine how much influence the speed of feeding and depth of feeding on AISI 1045 steel and AISI 4140 steel materials used in shafts, conecting roads, gears with carbide chisels. With Vc=140 m/min, Vc=150 m/min, Vc=170 m/min, and Vc=180 m/min, and knowing the surface roughness of the workpiece using a carbide tool.  From the results of research on AISI 1045 and AISI 4140 steel for cutting along 50 mm with engine speed 1200 rpm and cutting depth 0.3 mm, as well as the cutting speed used Vc=140 m/min, Vc=150 m/min, Vc=170 m/min and Vc=180 m/min and the initial cutting distance of 4 mm, the time needed is 1,125 minutes. For the surface roughness value of AISI 1045 steel material and AISI 4140 steel has four variations in lathe feeding speed in this study, which in each variation has a different surface roughness value, the smallest surface roughness value is AISI 4140 steel with a feeding speed vc = 180 m / min surface roughness value of 0.705 μm compared to AISI 1045 steel material. This is due to the greater the movement of the feeding speed of feeding, the smaller the value of the surface roughness of the material

Abstract

The purpose of this study to determine the effect holding time on increasing the surface hardness of AISI 1020 steel material and analyzing the physical and mechanical properties of the results pack carburizing cassava peel waste on AISI 1020 steel. Process pack carburizing in this study have variations temperature 875oC and 900oC withholding time 60 minutes, 80 minutes, 100 minutes and 120 minutes. The catalyst used in this study was a carbonate compound, namely 20% BaCo3 to accelerate the reaction of adding carbon. The research results show that pack carburizing from cassava peel waste carbon can increase the surface hardness of AISI 1020 steel or part of the mechanical properties of the material. Testing at a temperature of 875oC withholding time 60 minutes which is 10.7 HRC and is the lowest value in the study while the highest hardness value occurs at a temperature of 900OC withholding time 120 minutes is 48.2 HRC. Microstructure observation results (metallography) on the edges indicates the martensite phase. The more martensite phase, the higher the value of the surface hardness of the steel material in the same direction as the effect of the length of holding time(holding time)

Abstract

The goal of this study is to determine the effect of the matrix-to-filler ratio on the characteristic value of composites made from pineapple leaf fiber and coco fiber using clear polyester resin 108 as a matrix. The composite printing process involves combining 70% resin and 5% pineapple fiber: 15% pineapple fiber, 25% coconut fiber: 15% coconut fiber, 25% pineapple fiber, and 5% coconut fiber with 1% catalyst. The Hand-Lay Up method is used to create composites. Tensile strength testing mechanical properties are based on standards (ASTM D-3039). The tensile strength of 25% pineapple leaf fiber is the highest in this percentage variation: 5% coconut fiber with an average value of 44.88 MPa, 3.37% tensile strain, while pineapple leaf fiber 5% has the lowest tensile strength value: 25% coconut fiber with a 25.26 MPa average and a 2.54% tensile strain. According to the findings, the composite of 25% pineapple leaf fiber: 5% coconut fiber immersed in NaOH is suitable for use as an alternative tensile material.
