Abstract

Bawang merah merupakan bahan yang digunakan untuk membuat bawang goreng. Salah satu tahap pengolahan bawang merah menjadi bawang goreng adalah dengan mengiris bawang dengan ketebalan tertentu kemudian digoreng menggunakan minyak panas. Produsen bawang goreng ataupun industri kuliner masih banyak yang memproduksi bawang goreng masih mengiris bawang secara manual. Oleh karena itu, dirancang teknologi tepat guna berupa mesin pengiris bawang merah dengan sistem mata pisau rotari sumbu vertikal. Cara kerja mesin adalah dengan memutarkan mata pisau menggunakan motor listrik 200 watt dengan putaran 350 rpm dan dimensi mesin dengan panjang 53 cm x lebar 42 cm x tinggi 105 cm. Hasil penelitian diperoleh kapasitas output mesin pengiris bawang merah mampu mengiris bawang merah dengan hasil rata-rata bawang kategori baik adalah 454,66 gram, 30 gram kategori tidak baik, dan kategori tertinggal 15,33 gram dengan waktu pengirisan 59,62 detik. Kapasitas produksi mesin pengiris bawang merah ini sebesar 27,432 Kg/jam dengan tingkat efisiensi produksi mesin mencapai 90,93%

Abstract

This research about how to modify a machine that peels onions. The method used is Reverse engineering. This machine was modified because there is a shortage, level of success onion-peeler machine is still low, with value 43.63%, safety level machine is not sufficient, and the diameter of peeler tube hole is too large, so it is not effective and efficient. Modification made for to improve the efficiency of peeling shallots. The modified part is the rubber and the diameter of the peeler hole. Tube-hole size changed from 16mm to 6mm. will use the Shaft On the stripper tube. The shaft works like a holder for a rubber peeler. There are 11 pieces of peeling rubber. The results of the study showed that the peeled onion was 755 grams after 20 minutes. The machine's actual capacity is 37.75 grams per minute, or 2.26 kg per hour. The machine's production efficiency is 75.5%.

Abstract

Tea (camellia sinensis) is one type of plant that is often found as a processed beverage. There are several raw materials for making tea that are often used including using leaves, shoots, flowers, and roots. One of the teas made from roots is bajakah root tea where the manufacturing process is still done in the traditional way, namely chopped using a machete. Therefore, in this study, a bajakah root chopping machine was designed with the aim of helping the bajakah root production process into tea powder. This bajakah root chopping machine into tea powder is designed using the France method with the demands of a sturdy frame and easy to move. This bajakah root chopping machine has dimensions of 340 mm long, 240 mm wide and 600 mm high. The engine is driven by an electric motor with a power of 0.5 Hp, a rotation of 1400 rpm using a pulley drive system with a ratio of 1: 1.5 and the rotation of the chopper shaft is 933 rpm. From the test results taken from a sample of 500 grams of raw material with 3 times testing, the resulting average is perfectly chopped as much as 389 grams, not perfectly chopped as much as 54 grams, with a time of 167.3 seconds. The production capacity of the machine is 8.37 kg/hour.  The machine that has been made is able to chop bajakah roots with a machine production efficiency of 77.8%.

Abstract

Indonesia is an agricultural country where the majority of the population is farming. Farmers in Indonesia still use many traditional methods in processing agricultural land such as using hoes. In previous studies, a soil bulking machine was made with a slope of the plow blade angle of 90 ° and obtained less than optimal loose results. The influencing factor is that the angle of the hoe eye is not large, therefore the manufacture of a soil bulking machine is carried out using a hoe-shaped plow with the slope of the corner of the hoe eye enlarged to 110 °. The soil bulking machine uses 30 hoe-shaped plowshares with a hoe blade height of 10 cm, a width of 10 cm and a hoe tip thickness of 6 mm. The type of soil that can be plowed by this soil bulking machine is soil that has been cultivated on agricultural land. The test was conducted on an area of 28 m2. In the first experiment, it took an average of 18.78 seconds with an average pirated depth of 9.76 cm. In the second experiment, it took an average of 16.91 seconds with an average pirated depth of 9.30 cm. In the third experiment, it took an average of 19.24 seconds with an average pirated depth of 11.26 cm. The result of soil loosening with an average productivity of 1.53 m2 / second with an average depth of 10.10 cm.
