Abstract

AbstractMedians variety of potato is the main commodity developed by Agricultural Technology Park, Cikajang, Garut, West Java. The product has been partially sold in raw form and partly processed by itself into potato chips. This article will analyze the technical and financial feasibility of two ways of potato chips production. Production of potato chips has done manually by several machine units, therefore it needs to analyze technically and financially. Some analysis have conducted for this technical and financial analysis. The results showed that the average slicing capacity by slicing machine was 71.160 kg/hour, with the result of perfect shape about 58.493%. During five-year project, the cost of sold, break event point, benefit cost ratio, net present value, benefit cost ratio, and payback period by slicing machine were around of 55,591 Rp/kg, 612 kg/year, 459,639,059 Rp/year, 1.41, 17.17% and four months, respectively. In contras by traditional manner that the cost of sold, break event point, benefit cost ratio, net present value, benefit cost ratio, and payback period were nearly of 59,248 Rp/kg, 507 kg/year, 260,787,383 Rp/year, 1.35, 23.22% and four months, respectively.AbstrakKentang industri varietas Medians merupakan komoditi utama yang dikembangkan Taman Teknologi Pertanian, Cikajang, Garut, Jawa Barat. Hasil produksi sebagian dijual dalam bentuk mentah dan sebagianlagi diolah sendiri menjadi keripik kentang. Produksi keripik kentang dilakukan secara manual dan menggunakan beberapa unit mesin, sehingga diperlukan analisis teknis dan finansial untuk keberlanjutanusaha produksi keripik kentang. Analisis yang dilakukan meliputi kapasitas kinerja mesin pengiris, rendemen hasil irisan, HPP, BEP, NPV, BCR, IRR dan PBP. Hasil penelitian menunjukkan rata-rata kapasitas pengirisan mesin pengiris adalah sebesar 71.160 kg/jam, dengan hasil irisan yang memiliki bentuk sempurna sebesar 58.493%. Pada umur proyek lima tahun, produksi keripik kentang secara mekanis didapatkan HPP sebesar Rp.55,591/kg, BEP sebesar 612 kg pertahun, NPV sebesar Rp.459,639,059/tahun, BCR sebesar 1.41, IRR sebesar 17.17% dan modal akan kembali pada bulan keempat. Sedangkan pada produksi keripik kentang secara manual didapatkan HPP sebesar Rp.59,248/kg, BEP sebesar 507 kg pertahun, NPV sebesar Rp.260,787,383/tahun, BCR sebesar 1.35, I.RR sebesar 23.22% dan modal akan kembali padabulan keempat.

Abstract

Soil temperature and humidity are important factors for plant growth. In the early and vegetative phases, plants require high humidity while in the late phase plants require low humidity. Soil temperature and humidity measuring instruments have been successfully made but are not yet connected to the internet network so that the sensor readings must be read directly on the LCD screen. This study aims to design an android-based soil temperature and humidity monitoring system. The monitoring system that was built is equipped with an SD Card as a backup of sensor reading data in case the internet is unstable. The method used in this research is engineering with the stages of literature study, analysis and design, hardware manufacturing, software development and system testing. The results show that there are 3 sensors, namely the DHT22 sensor, DS18B20 sensor, and the moisture sensor which are controlled by NodeMCU ESP32 with a battery power source of 3000 mAh 7.2 V which is step down to 5.0 V by LM2596. The system has a battery life of 10 hours 27 minutes, a soil temperature sensor accuracy of 98.05%, a soil moisture sensor accuracy of 90.2%, an air temperature accuracy of 98.3%, and an air humidity accuracy of 96.88%.
