Industri rumah tangga merupakan salah satu jenis industri yang mudah dilakukan dan tidak membutuhkan modal besar. Dibutuhkan suatu alat penunjang dalam menjalankan usaha rumah tangga agar usaha tersebut dapat berjalan dengan baik. Penelitian ini dilakukan untuk mengetahui desain mesin, daya motor dan sistem kerja mesin spiner untuk industri rumah tangga tersebut. Hasil perancangan menunjukkan bahwa rancangan mesin spinner vertikal yang dibuat dapat beroperasi dengan baik dalam penirisan singkong parut dan kelapa parut dengan menggunakan motor listrik. Perancangan mesin spinner peniris vertikel yang dibuat memiliki tiga variasi kecepatan yaitu kecepatan I (1410 RPM), kecepatan II (1461 RPM) dan kecepatan III (1471 RPM). Pengujian alat dilakukan sebanyak tiga kali yaitu dalam waktu 5 menit, 10 menit dan 15 menit. Pengurangan massa bahan pada menit ke 10 hingga 15 cenderung lebih sedikit dimasing-masing kecepatan. Dari penelitian ini dapat disimpulkan bahwa penirisan pada singkong parut lebih efektif dilakukan di kecepatan ke III dengan waktu 10 menit dan massa yang tersisa sebesar 1,399 kg. Sedangkan hubungan antara waktu terhadap massa kelapa menghasilkan pengurangan massa bahan terbesar terjadi di 5 menit awal disetiap kecepatan. Sedangkan pengurangan massa pada menit ke 10 hingga 15 cenderung lebih sedikit pada masing-masing kecepatan.

Every year the use of fossil fuels has increased, which requires finding alternative energy sources to replace fossil fuels. The existence of plastic waste, especially HDPE plastic and rice husks, is a potential to be used as renewable energy in the form of briquettes. This research was conducted to determine the potential use of plastic powder and biomass as an alternative fuel. The biomass used in this research is rice husk and HDPE plastic. To determine the quality of briquettes, several variations of the mixture of rice husks were used, namely: sample 1 = 90% rice husk + 10% High Density Polyethylene (HDPE) plastic, sample 2 = 80% rice husk + 20% High Density Polyethylene (HDPE) plastic, sample 3 = 70% rice husk + High Density Polyethylene (HDPE) plastic 30%, sample 4 = 100% rice husk. The test parameters used are proximate test (calorific value), flame length test, briquette resistance test. The test results obtained briquettes in sample 3 have a calorific value of 7586,853 cal/g and have a combustion rate value of 0,83 grams/minute.Keywords: Briquettes, Rice Husk, High Density Polyethylene (HDPE) Plastic, Calorific Value

Regarding the conversion system with a thermoelectric element which allows it to be used anytime and anywhere, that's why you need to position the tool correctly. With that, the research aims to find out the voltage produced and the performance of thermoelectrics as a generator of electrical energy. The method used in this research is a system for converting briquette heat energy into electrical energy. The variations in the research experiment are fan cooling 1, fan cooling 2 and water cooling. By using a charcoal briquette heater and three variations of cooling, the average voltage of cooling fan 1 0.660 V, cooling fan 2 0.769 V, water cooling 0.903 V can be produced and the average current of cooling fan 1 is 0.029 A, cooling fan 2 is 0.034 A, cooling Water 0.039 A. The characteristics of the resulting temperature difference show a significant increase along with the length of combustion time. The resulting voltage is higher if the hot combustion of the briquettes is carried out with a variation of water cooling. Keywords: Briquettes, electricity, hot side, thermoelectric, and voltage
