Abstract

Proses pemotongan tempe pada sebagian besar usaha mikro, kecil, dan menengah (UMKM), khususnya di Sentra Industri Keripik Tempe Sanan, Kota Malang, masih dilakukan secara manual sehingga menghasilkan ketebalan irisan yang kurang seragam, kapasitas produksi yang terbatas, serta membutuhkan waktu dan tenaga kerja yang relatif besar. Penelitian ini bertujuan merancang dan merealisasikan mesin pemotong tempe dengan sistem hopper dan mekanisme pemberat, serta menganalisis kinerja mesin berdasarkan hasil pengujian ketebalan irisan, waktu pemotongan, dan kapasitas produksi. Metode penelitian meliputi studi literatur, identifikasi kebutuhan, perancangan konsep, perancangan detail, fabrikasi, perakitan, serta pengujian kinerja mesin. Mesin menggunakan motor AC 0,2 kW sebagai penggerak utama dengan sistem transmisi pulley dan V-belt, sedangkan mekanisme feeding memanfaatkan hopper dan pemberat berbasis gaya gravitasi untuk menjaga kontinuitas pemasukan tempe menuju pisau pemotong.Hasil penelitian menunjukkan bahwa penggunaan mekanisme pemberat berpengaruh terhadap proses feeding dan waktu pemotongan. Kondisi operasi terbaik diperoleh pada penggunaan empat buah pemberat dengan massa total 1.031 gram, yang menghasilkan waktu pemotongan sekitar 30–32 detik dengan kapasitas produksi rata-rata sebesar 26,32 kg/jam. Pada kondisi tersebut mesin mampu menghasilkan irisan tempe yang relatif utuh dengan persentase lebih dari 90%. Namun demikian, mesin masih mengalami keterbatasan dalam menghasilkan ketebalan irisan di bawah 3 mm, serta kualitas hasil pemotongan dipengaruhi oleh umur tempe, dimana tempe yang lebih tua memiliki tekstur lebih keras sehingga memerlukan gaya potong yang lebih besar. Berdasarkan hasil penelitian, mesin pemotong tempe yang dirancang telah memenuhi tujuan perancangan dan berpotensi diterapkan pada skala UMKM sebagai alternatif untuk meningkatkan efisiensi proses pemotongan dan menghasilkan irisan tempe yang lebih seragam.

The tempeh slicing process in most Micro, Small, and Medium Enterprises (MSMEs) is still performed manually, resulting in inconsistent slice thickness, limited production capacity, and a high dependence on operator skills. This condition encourages the development of a simple slicing machine capable of improving production efficiency while producing more uniform slices. This study aimed to design, fabricate, and evaluate the performance of a tempeh slicing machine equipped with a hopper and weighted feeding mechanism. The research methods consisted of literature review, needs identification, concept design, detailed design, fabrication, assembly, and performance testing. The machine utilized a 220 V AC motor rated at 200 W as the primary power source. Power was transmitted through a pulley and V-belt system to a rotating horizontal blade. The hopper and weighted feeding mechanism were designed to provide a constant gravitational force, ensuring continuous material feeding toward the cutting area. Performance evaluation included slice thickness, cutting time, production capacity, and the effect of different counterweight masses. Experimental results showed that the best operating condition was achieved using a total counterweight of 1.031 kg, producing intact tempeh slices with an average thickness of approximately 3 mm, a cutting time of 30–32 seconds, and an average production capacity of 26.32 kg/h. Increasing the counterweight improved feeding stability and significantly reduced cutting time.However, the machine was unable to consistently produce slices thinner than 3 mm, and the hardness of older tempeh affected cutting quality because higher material stiffness increased the cutting resistance. Overall, the developed machine successfully met the design objectives by providing a stable feeding system, increasing production capacity, and producing relatively uniform slices. Therefore, the proposed design has the potential to be applied in MSME-scale tempeh chip production.
