Abstrak Salah satu UMKM yang mengolah sagu untuk dijadikan mie sagu adalah “Mie Sagu Barokah” milik Bapak Rahmat yang memiliki kapasitas produksi 50 kg sampai 70 kg per hari. Seperti biasanya, dalam mengolah batang sagu untuk dijadikan pati sagu masih menggunakan cara tradisional dan semi mekanis. Pemarutan batang sagu untuk dijadikan pati sagu dilakukan di rumah yang juga merupakan tempat usaha mie sagu.Dari hasil survey dan wawancara, proses pemarutan batang sagu yang selama ini dilakukan memiliki beberapa kelemahan yaitu 1.Ongkos angkut batang sagu masih mahal, 2.Memerlukan tempat yang luas, 3.Suara mesin pemarut yang sangat menggangu tetangga, 4.Bau dari tumpukan kulit batang sagu.Tujuan penelitian ini adalah membuat alat pemarut batang sagu portable dan melakukan analisa ongkos produksi penggunaan alat pemarut batang sagu portable. Dari hasil penelitian diperoleh waktu rata-rata pemarutan tual batang sagu sebesar 4,14 menit dengan biaya sebesar Rp. 226,79/kg. Kata kunci : batang, sagu, portable,pemarut, alat, produksi

Abstrak Mekanisme penyaringan air yang digunakan pengusaha air minum isi ulang di Kabupaten Bengkalis adalah perangkat pengolah depot air minum yang dijual oleh perusahaan atau agen grosir air minum. Dalam pemakaiannya, komponen terpenting pada pengolah air minum ini yaitu cartridge filter, apabila sudah banyak kotoran yang menempel, dibersihkan dengan cara manual. Hal ini disebabkan belum tersedianya alat pembersih atau pencuci khusus cartridge filter di pasaran. Pembersihan cartridge filter yang dilakukan saat ini dengan cara disemprot dengan air bertekanan, lalu cartridge filter tersebut dipukul berulang-ulang dengan kekuatan sedang pada permukaan lantai. Dalam penelitian ini dibuat sebuah prototip pencuci cartridge filter tanpa merusak dan dengan demikian menghasilkan air minum isi ulang yang higienis. Hasil ujicoba alat pencuci cartridge filter di tempat mitra diperoleh waktu rata-rata pencucian untuk 12 cartridge sebesar 02 jam 42 menit 17 detik, dengan tiga tahap pencucian. Sedangkan rata-rata Total Dissolved Solid (TDS) dengan prototip alat pencuci cartridge filter ini sebesar 6.6 ppm Kata kunci : alat pencuci cartridge filter, air minum isi ulang, TDS

Potensi perikanan Republik Indonesia memenangkan pasar MEA (Masyarakat EkonomiASEAN) dan produk makanan olahan hasil laut telah meraih green ticket yang dikeluarkan oleh USAFDA sehingga beberapa industri pengolahan hasil laut menembus pasar AS dan Eropa. Desa PanipahanKecamatan Pasir Limau Kapas sebagai besar bermata pencaharian sebagai nelayan. Merekamemanfaatkan hasil tangkapan berupa udang rebon untuk diolah menjadi terasi, untuk mengetahuiperbandingan kapasitas hasil gilingan dengan variasi diameter lubang pengeluaran alat penggiling terasidan untuk mengetahui rendemen dengan variasi diameter lubang pengeluaran..Upaya untuk pembuatanalat ini menggunakan extruder yang berfungsi untuk menggiling udang rebon kebagian die.Hasildesakan udang rebon tersebut kemudian digiling dengan jumblah pisau penggiling 2 mata pisauyangdipasang bertingkat dengan kecepatan 1400 RPM dengan daya 1 Hp. Menggunakan sistempenggiling ini bahan baku dapat tergiling lembut yang kemudian dikeringkan dan dibentuk sesuai dengakebutuhan. Untuk menegetahui bahwa terasi hasil dari alat itu layak untuk dipasarkan ataupundikosumsi maka dilakukan pengujian densitas. Setiap perbedaan lubang keluaran maka berbanding lurusdengan perbedaan hasil berat terasi yang mana diameter lobang keluaran 3 mm menyusut dalam waktu8,49 menit, 8,55menit dan 9,11 menit. Diameter lubang keluaran 4 mm menyusut dalam waktu 6,29menit, 6,40 menit, dan 7,21 menit, dan diameter lubang keluaran 5 mm menyusut dalam waktu 6,9menit, 6,12 menit, dan 7,11 menit. Semakin lamawaktu penjemuran udang rebonsemakin basar pulanilai penyusutan pada berat udang, begitu juga semakin kecil lubang diameter dies akan menghasilkannilai densitas yang tinggi.

The making process of Lempuk Durian is almost same as Dodol’s, the difference is only at the mixing of sticky rice (ketan). Dodol is made with the mixing of sticky rice while Lempuk isn’t. Durian flesh is separated by its contents and then finely ground with a grinding machine. The process of separating the contents and seeds of durian fruit is still using conventional methods, by using a punch-filled basket while being pressed by hand. This way can cause injury to the hand, this way can cause injury to the hand, requires a long time and workers get tired more quickly. The purpose of this research is to make content and durian seed separator machines and conduct performance analysis. This content and durian seed separator machine has a capacity of 20kg / production. After testing and observing the durian seed separator machine, then the performance analysis is carried out to determine the ability of the machine. Machine working capacity (KKM) is obtained at 1 kg / minute with the value of the separation of contents and durian seeds of 87%.

Welding is one of the essential processes in the manufacturing industry. One of the factors that affects the quality of welding results is the cooling medium used after the welding process. This study aims to determine the effect of different cooling media on the tensile strength of SMAW (Shielded Metal Arc Welding) welded joints on ASTM A36 steel. Three types of cooling media were used air, water with a pH of 6.5–8.5 and SAE 10W-40 oil. The welding process was carried out using an I-groove with a butt joint in the 1G position, using an E7018 electrode with a diameter of 3.2 mm and a current of 100 A. The tensile tests were conducted according to the ASTM E8 standard.The results showed that the specimens cooled with SAE 10W-40 oil produced the highest average tensile strength of 574.9974 Mega pascal and the highest average elongation of 38.73%. Cooling with water resulted in an average tensile strength of 566.5932 Mega pascal and a maximum elongation of 28.27%. Meanwhile, cooling with air resulted in the lowest average tensile strength of 545.5592 Mega pascal and an elongation of 30%. The highest modulus of elasticity was obtained from water cooling at 2051.55 Mega pascal, followed by air at 2048.60 Mega pascal, and the lowest was from oil at 1493.83 Mega pascal.Based on these results, it can be concluded that the variation of cooling media affects the tensile strength of welded joints. Cooling with SAE 10W-40 oil provided the most optimal results, producing the highest tensile strength and good ductility. Therefore, SAE 10W-40 oil is recommended as the best cooling medium for the SMAW welding process on ASTM A36 steel, especially in ship hull applications. Keywords: SMAW, ASTM A36 Steel, cooling media, tensile strength, I-groove, butt joint, ship hull.

This study analyzes the troubleshooting process of an overheating cooling system in a single Honda Jazz i-DSI engine used as a practical training unit at the Heavy Equipment Engineering Workshop, Politeknik Negeri Padang. A case study approach with descriptive analysis was applied through identification of overheating symptoms, inspection of cooling system components, functional testing, examination of coolant hose configuration, repair, and temperature verification. The inspection showed no blockage in the radiator, the V-belt met the inspection criteria, the thermostat opened at 80°C and fully opened at 95°C, and no mechanical damage was found in the water pump. The coolant level was low, while radiator cap pressure performance and temperature sensor accuracy were not quantitatively verified. Further inspection identified reversed inlet and outlet radiator hose installation. After correcting the hose configuration and refilling the coolant, the maximum coolant temperature decreased from 116.25°C to 95°C and subsequently decreased to 85°C. The findings indicate that incorrect hose configuration was associated with overheating in the investigated case.
