PENERAPAN TEKNOLOGI PEMOTONGAN HEWAN PADA USAHA SATE KAMBING “PUTRO WIDODO” SEMARANG

ABSTRAKKegiatan pengabdian ini merupakan keberlanjutan dari pengabdian yang sudah dilaksanakan pada mitra, yaitu usaha sate kambing “Putro Widodo” di Semarang, yang mempunyai masalah terkait proses pemotongan/penyembelihan kambing. Sate Widodo Sampangan Semarang tiap hari menyembelih rata-rata 6 ekor kambing. Proses penyembelihan dan pengambilan daging tiap ekor kambing membutuhkan waktu 1 jam karena dikerjakan tanpa bantuan alat yang memadai. Sebagai solusinya, tim pelaksana bersama mitra pengabdian akan merancang dan membuat alat bantu pemotongan kambing berupa meja khusus yang ergonomis yang menyatu dengan tiang gantungan kambing sebagai sarana menarik kulit kambing dan proses pemisahan daging dengan tulangnya menjadi mudah. Proses penarikan kulit nantinya dengan bantuan katrol penarik (hoist) dengan sumber tenaga motor listrik sehingga meringankan pekerja. Sebagai tim pelaksana kegiatan ini melibatkan dosen dan mahasiswa dengan bidang keahlian yang sesuai dengan kebutuhan lapangan. Dalam pembuatan mesin/alat yang akan diterapkan di mitra akan dilaksanakan di workshop jurusan Teknik Mesin FT Unnes, dengan melibatkan teknisi dan mahasiswa. Metode pengabdian ini yaitu: 1) Penyuluhan, 2) Demontrasi, 3) Praktik Langsung, dan 4) Pendampingan. Pelaksanaan pengabdian dilakukan pada saat hari raya Idul Adha 1444 H di salah satu kompleks perumahan di Kota Semarang. Kelayakan desain alat mendapatkan skor presentase sebesar 83,1% yang dapat diartikan bahwa desain alat bantu penyembelihan dan pengulitan kambing sangat layak untuk digunakan. Efektivitas dan efisiensi alat bantu penyembelihan dan pengulitan kambing mendapat skor sebesar 82,5% yang dapat disimpulkan bahwa alat bantu penyembelihan dan pengulitan kambing sangat efektif dan efisien. Dan aspek ergonomi mendapat skor 85% yang dapat diartikan alat bantu penyembelihan dan pengulitan kambing ini sangat ergonomis. Kata kunci: kambing; pengulitan; penyembelihan; teknologi ABSTRACTThis service activity is a continuation of the service that has been carried out with partners, namely the goat satay business "Putro Widodo" in Semarang, which has problems related to the goat slaughtering and slaughtering process. Sate Widodo Sampangan Semarang slaughters an average of six goats every day. The process of slaughtering and taking the meat from each goat takes 1 hour because it is done without the help of adequate tools. As a solution, the implementing team, together with service partners, will design and make a goat slaughtering tool in the form of a special ergonomic table that is integrated with the goat gallows as a means of pulling the goat skin and making the process of separating the meat from the bones easy. The process of pulling the skin will be done with the help of a pulley (hoist) with an electric motor power source, thereby making it easier for workers. As a team implementing this activity, it involves lecturers and students with areas of expertise that suit the needs of the field. The manufacture of machines and tools that will be implemented by partners will be carried out in the Mechanical Engineering department workshop at FT Unnes, involving technicians and students. The methods of this service are: 1) counseling, 2) demonstration, 3) direct practice, and 4) mentoring. The dedication was carried out during the Idul Adha 1444 H holiday in one of the housing complexes in Semarang City. The feasibility of the tool design received a percentage score of 83.1%, which means that the design of the tool for slaughtering and skinning goats is very suitable for use. The effectiveness and efficiency of goat slaughtering and skinning aids received a score of 82.5%, indicating that goat slaughtering and skinning aids are very effective and efficient. And the ergonomics aspect received a score of 85%, which means that this goat slaughtering and skinning aid is very ergonomic. Keywords: goat; skinning; slaughter; technology

Analisis Statis Desain Chassis Kendaraan Listrik 2 Penumpang

Tujuan penelitian ini adalah untuk mendapatkan sebuah rancangan chassis kendaraan listrik yang aman dan nyaman. Metode penelitian yang digunakan adalah metode Research And Development (R&D) dengan bantuan perangkat lunak (software) yang mampu untuk pembuatan suatu model dalam bentuk gambar 3 dimensi, dalam hal ini software yang digunakan adalah Autodesk Inventor 2019. Autodesk Inventor 2019 dapat menguji kontruksi chassis yang dapat mengetahui nilai Von-Misses Stress, Displacement dan Safety Factor pada konstruksi frame kendaraan listrik. Dari hasil analisis perancangan chassis kendaraan listrik diperolehkan hasil pengujian yang dilakukan secara perhitungan komputer dimana angka dari tiap-tiap bagian yang diuji nilai safety factor sangat aman. Hasil penelitian ini menunjukkan bahwa desain chassis yang dibuat adalah jenis ladder frame yang dapat digunakan untuk kendaraan listrik 2 penumpang. Nilai Von-misses stresses pada material Steel AISI 1035, Besi Hollow ASTM A 500 dan Aluminium Alloy AA 6063-T6 berturut-turut adalah 5.53 x 107 Pa, 5.52 x 107 Pa dan 5.53 x 107 Pa. Nilai Displacement pada material Steel AISI 1035, Besi Hollow ASTM A 500  dan Aluminium Alloy AA 6063-T6 berturut-turut adalah 0.141 mm, 0.141 mm dan 0.250 mm. Nilai Safety factor pada material Steel AISI 1035, Besi Hollow ASTM A 500 dan Aluminium Alloy AA 6063-T6 berturut-turut adalah 6.689, 4.875 dan 3.067. Desain chassis ladder frame yang dibuat dengan material Steel Aisi 1035 memiliki safety factor yang lebih tinggi dibandingkan dengan material Besi Hollow ASTM A 500 dan Aluminium Alloy AA 6063-T6. Tetapi pada tahap fabrikasi di lapangan lebih memilih material Besi Hollow ASTM A 500, alasanya menggunakan material Besi Hollow ASTM A 500 karena material Besi Hollow ASTM A 500 memiliki nilai yield strength yang tidak jauh dengan material Steel Aisi 1035. Dan alasan lainya yaitu karena Besi Hollow ASTM A 500 memiliki nilai safety factor yang sudah di atas angka 4 dan pastinya harga Besi Hollow ASTM A 500 relative lebih terjangkau dibandingkan dengan material Steel Aisi 1035

Thermal shock resistance investigation of evaporation boat waste-based crucibles

A crucible is a container shaped like a pot or a bowl used for smelting non-metallic materials, quality of the crucible can be influenced by several factors, including the selection of the constituent materials, the particle size used the amount of compaction pressure, and the length of firing time in the furnace. The selection of constituent materials is done by selecting the crucible-making mixture. The use of crucibles is for pyrometallurgical processes used for gold processing. Waste is closely related to pollution because this waste is the substance of environmental pollution therefore, waste treatment is needed so that it does not pollute the environment, the principles of solid waste management are prevention, recycling one example of solid waste is evaporation boats. Evaporation boats are included in one of the refractory materials because the waste from evaporation boats contains boron nitride (BN) and titanium diboride (TiB2) materials. So the purpose of this research was to determine thermal shock resistance of evaporation boat waste-based crucibles. The process of making specimens begins with crushing the evaporation boat waste with a crusher machine into powder, then sieved using a 120-mesh, then mixed with graphite, kaolin, and molasses using a mixer for 90 minutes until homogeneous mixture. The mixed material is then cast using molds according to ASTM D256 standards and pressed or compacted with a compacting tool worth 40 MPa. The specimens were then dried in an oven for four hours at 100°C, after that, the specimens were sintered at 1000 °C for 2 hours with a heating rate of 4 °C/min. The Compositions evaporation boat waste, graphite, kaolin, and molasses (75%, 15%, 10%, 30%; 75%, 20%, 5%, 30%; and 75%, 25%, 0%, 30%) are the materials used. Thermal shock treatment temperatures range from 100°C to 200°C, 300°C to 400°C, and up to 500°C. The results showed the highest average value of impact resistance was in composition 3 (75%, 25%, 0%, 30%) with a thermal shock temperature of 100°C worth 0.00501 J/mm2, and the lowest was in composition 2 (75%, 20%, 5%, 30%) at a thermal shock temperature of 500°C worth 0.00359 J/mm2. The average impact resistance value for each composition decreases, which is followed by an increase in the thermal shock temperature, This is because the higher the temperature of the thermal shock, the harder the specimen becomes and the specimen becomes brittle, variations in evaporation boat waste, graphite, kaolin, and molasses as crucible materials will be better if the use of kaolin in these compositions has a low presentation, even the highest average impact resistance value is in compositions that do not use kaolin on specimen composition 3
