Abstract

Kacang sangrai merupakan salah satu jenis pengolahan kacang tanah yang memiliki potensi ekonomi yang cukup besar peluangnya di Indonesia. Kacang sangrai cukup digemari sebagai cemilan karena rasanya yang manis dan masa penyimpanannya tahan lama. Untuk dapat efektif, diperlukan pula cara penyangraian yang benar. Seperti pengaturan temperatur dan lama penyangraiannya. Adapun jenis penyangraian yang menggunakan bantuan media pasir.Penelitian ini dilakukan untuk melakukan pengujian eksperimental terhadap proses penyangraian kacang, Dimana proses penyangraian dilakukan dengan 2 variabel bebas, yaitu variasi suhu dan variasi media penyangraian. Untuk suhu menggunakan 3 variasi pengujian, yaitu 150 C, 165C, dan 180C. Sedangkan variabel media penyangraian menggunakan 2 variasi, yaitu dengan menggunakan media pasir dan tanpa menggunakan media pasir. Metode pengambilan data berupa pengambilan data eksperimental temperatur di 5 titik setiap 5 menit sekali. Dilakukan hingga kacang berubah warna kecoklatan (matang). Dari hasil pengujian, didapatkan hasil kacang sangrai yang baik pada saat pengujian temperatur 180 C dengan menggunakan bantuan media pasir. Tingkat kegosongan kacang sebesar 2% dari 1 Kg pengujian, butir kacang rusak sebanyak 18gr, lama waktu penyangraian 1 kg kacang selama 25 menit, dan pengurangan kadar air pada kacang mencapai 20%

Abstract

Young Jackfruit (Artocarpus heterophyllus) is a tropical fruit that grows in various regions, including Southeast Asia. While typically harvested when ripe, it is also consumed in its young stage. This final project focuses on the design and development of a Vertical Young Jackfruit Skin Peeling Machine utilizing the Turning Process Method. The proposed peeling machine is powered by a 1 hp motor with a speed of 1450 rpm, which is transmitted to 100 rpm. The machine's driving mechanism comprises a single transmission system, consisting of a pair of pulleys connected by a V-belt. When the motor is activated, the rotation is directly transmitted from pulley 1 to pulley 2, mounted on a 25 mm diameter shaft that rotates the young jackfruit using a V-belt intermediary. As the shaft rotates, a knife applies pressure on the rotating young jackfruit, moving from bottom to top. This movement is facilitated by a threaded shaft mechanism driven by the rotation of the fruit-driving shaft, which receives the rotational transmission from pulley 1 to pulley 2, mounted on a 25 mm diameter shaft to a 17 mm diameter shaft with a rotational speed of 40 rpm. The peeling process is conducted according to the dimensions of the young jackfruit, from bottom to top.
