Abstract

Gampong Meunasah Mesjid Puenteut merupakan salah satu desa yang terletak di Kecamatan Blang Mangat Kota Lhokseumawe. Gampong Meunasah Mesjid Puenteutletaknya 9 km kearah timur Kota Lhokseumawe dengan jumlah penduduk sekitar 4564 jiwa, umumnya Masyarakat Gampong Meunasah Mesjid kegiatan sehari-hari sebagai petani dan sebagian kecil PNS dan wiraswasta.Rendahnya tingkat pendidikan masyarakat di desa ini merupakan salah satu faktor yang berkonstribusi memberikan rendahnya tingkat perekonomian desa. Masalah yang dihadapi mitra adalah banyak pemuda yang putus sekolah di usia produktif yang tidak mempunyai keahlian tambahan sehingga tidak mempunyai peluang untuk mencari kerja yang menyebabkan meningkatnya angka pengangguran. Berdasarkan hal diatas dengan memperhatikan kondisi mitra maka solusi yang ditawarkan untuk mengatasi permasalahan tersebut adalah dengan memberikan pelatihan dibidang otomotif khususnya sepeda motor. Metode pelatihan ini yang meliputi 30% teori dan 70% praktek dengan jumlah peserta yang mengikuti program pelatihan ini berjumlah 8 orang di mana para peserta semua adalah pemuda gampong Meunasah Mesjid Puenteut,Kecamatan Blang Mangat. Berdasarkan hasil evaluasi Teori dan Praktek, maka keseluruhan peserta dapat dikategorikan lulus dengan memperoleh nilai rata-rata 80. Nilai tersebut dapat dijadikan indikator kesuksesan pelatihan ini dalam mencapai sasaran pelatihan, seluruh peserta sudah memahami baik teori maupun praktek yaitu membongkar, menyetel dan memasang semua materi servis sepeda motor yang diberikan.Kata kunci: Sepeda motor,servis, komponen, ketrampilan.

Abstract

Kegagalan pada suatu konstruksi permesinan kemungkinan bisa terjadi, namun dapat dihindari dengan melakukan kajian-kajian dan penelitian. Penelitian ini dilakukan dengan tujuan untuk mengetahui kekuatan impak (impact strength) terhadap material baja karbon ST 60 pada berbagai temperatur, terutama pada temperatur ekstrim melalui uji impak charpy. Pengujian dilakukan melalui empat tahapan, yaitu: (1) mempersiapkan spesimen pengujian; (2) melakukan pengkondisian spesimen pada berbagai perlakuan temperatur; (3) melakukan pengujian impak charpy; dan (4) melakukan pengamatan perpatahan. Spesimen disiapkan dalam bentuk standar mengikuti ASTM E 23 sejumlah 24 buah sesuai dengan rancangan penelitian untuk 8 variasi temperatur dengan masing-masing 3 kali perulangan. Untuk mengkondisikan temperatur dapat dilakukan dengan menggunakan dapur pemanas (furnace) dan dry ice + alkohol 70% serta nitrogen cair. Pengujian impak dapat dilakukan dengan menggunakan alat uji impak charpy dan pengujian perpatahan (fractographi) dapat dilakukan dengan menggunakan Stereoscan Microscope. Hasil yang diperoleh menunjukkan bahwa, harga kekuatan impak material ST 60 terendah terjadi pada temperatur yang sangat ekstrim (-20 0C), yaitu sebesar 0,111 Joule/mm2, dan yang terbesar pada temperature 200 0C dengan harga 0,836 Joule/mm2. Temperatur transisi dari ulet ke getas untuk material ST 60, terjadi antara temperatur 0 0C sampai 150 0C, dimana pada rentang temperatur ini menunjukkan energi impak terjadi kenaikan yang tajam.Kata kunci: Baja karbon ST 60, impak charpy, kekuatan impak, perpatahan.

Abstract

Composite materials is increasingly experiencing an increa- sing trend, the manufacture of composites currently uses a lot of natural fiber reinforcement, Oil Palm Empty Fruit Bunches (OPEFB) fiber is a fiber that comes from oil palm empty fruit bunches waste that grows a lot in Indonesia and has the potential to be used as reinforcement in the manufacture of composites. With natural fiber reinforcement. The manufacture of composites in this study varied the fiber volume fraction by 5%, 15%, and 25%. Many previous studies on composite materials have focused on studying the physical and mechanical properties of composites. Even though damage to a structure or material is not only caused by static loads but also by dynamic loads. Vibration is a dynamic load experienced by material or structure, so it is necessary to determine the dynamic character of composite materials, one of the dynamic characteristics of materials is their natural frequency, the determination of the natural frequency in this study was carried out by using the finite element method in the ANSYS software. The results of the analysis in the form of tensile strength values and modulus of elasticity were obtained from tensile testing and dynamic characters in the form of natural frequencies and vibration modes were obtained from the analysis modal simulation process. From the results of the tensile test, it was found that the composite with a variation of 15% OPEFB fiber volume had the highest tensile strength and modulus of elasticity, as well as the results of the analysis modal simulation, a composite with 15% OPPEFB fiber, had the highest natural frequency value among the other two variations.

Abstract

Alternative products for water ice cubes have long been sought due to the spread of waterborne diseases and microplastic contamination, as they are often made from unhygienic water sources. Recently, stainless-steel ice cubes have been considered as one of the best alternatives, and they have been very popular in marketplaces, although very few studies found in the literature that have investigated their potential in replacing water ice cubes. In this study, the thermal performance of stainless-steel ice cubes will be explored experimentally using a combination of an Arduino microcontroller equipped with DS18B20 thermocouple sensors and a HIKMICRO B20 thermal camera with the aim to find out how good stainless steel ice cubes for cooling food and beverages.  The time evolution of water temperature in glasses filled with stainless-steel cubes of various brands is compared with that of water ice cubes. The temperature field obtained from thermal images is used to further observe the overall temperature of water in the glass. Leeseph stainless-steel ice cubes are found to have thermal performance comparable to water ice cubes, while SSGP ice cubes can retain lower temperatures for a longer time compared with other ice cubes. The effect of the number of ice cubes (N), the volume of water (V), and the average diameter of the glass used (D) are also investigated. At 1 ≤ N ≤ 4, the larger number of ice cubes used are found to lower the minimum temperature, and to decrease the minimum time,  while at 150 ml ≤ V ≤ 300 ml, the larger amount of water used are observed to increase the minimum temperature and to increase the minimum time, . At 53 mm ≤ D ≤ 66 mm, larger glass diameter used are found to increase both the minimum temperature, and the minimum time
