Abstract

Cassava cimplung is a traditional processed food made from cassava which is boiled in coconut sap water. Cassava has not been widely produced in ready-to-eat packaging as a selling value food. This is because cimplung is a semi-wet food so it easily spoils and does not last long. In an effort to maintain the quality of cassava cimplung, in this study a thermal pasteurization process was carried out with variations in the length of 10 minutes and 15 minutes and the use of EVOH (Ethylene Vinyl Alcohol) and boilpack packaging. Quality parameters observed included texture, pH, color, and brix content for 6 weeks of storage. The aims of this study were 1) To determine the effect of packaging type on the quality of cassava cimplung, 2) To determine the effect of pasteurization time on the quality of cassava cimplung, and 3) To determine the interaction effect of packaging type and pasteurization duration on the quality of cassava cimplung. The results of this study were 1)The treatment of the type of packaging was significantly different on the value of texture, pH, and color but was not significantly different on the brix content of cassava cimplung, 2) Pasteurization time treatment was significantly different to color value but not significantly different to texture, brix content, and pH of cassava cimplung, and 3) The interaction between the type of packaging and the duration of pasteurization was not significantly different on all quality parameters of cassava cimplung

Abstract

Precise and measurable water availability is an important aspect for optimal plant growth. It is necessary to monitor soil moisture continuously as a basis for watering. This paper presents the design of a soil moisture measurement system and testing of a capacitive type soil moisture sensor to obtain a calibration model on various types of soil. The measurement system is based on an Arduino-Mega microcontroller consisting of a soil moisture sensor, timer module, memory card module, keypad, LCD and irrigation actuator. In this research, five capacitive soil moisture sensors were tested on three types of soil, namely sand soil, and organic soil. Sand soil comes from the coast in Adipala Village, Cilacap Regency and organic soil comes from dry land in Kedungrandu Village, Banyumas Regency. The calibration process is based on the capacitive soil moisture sensor voltage (V) and soil water content (KA) values determined using the gravimetric method. The calibration model obtained for each soil is KA = 34.23 x V2 -182.84 x V + 249.45 (sandy soil), and KA = 2389 x V2 - 9252.6 x V + 9012.9 (organic soil). Soil moisture outputs, time data, and irrigation status are stored in the memory card.

Abstract

Rice is a major food crop in Indonesia that requires special attention in the milling process to ensure working time efficiency. This study aimed to identify the division of work elements in the rice milling process, determine the standard time used by operators, and provide recommendations for improving the work system in the Unsoed “Teaching Industry”. Data was collected by measuring the time of each work element in the rice milling process using a stopwatch. The work elements were divided into two groups: rice milling and rice packaging elements. The analysis methods included data adequacy and uniformity tests, as well as calculations of the normal time and standard time. The results of the analysis showed that the standard time for the rice milling process was 5,920.55 seconds per 100 kg of rice, while the standard time for the rice packaging process reached 27,549.81 seconds per 100 kg of rice. The time required was still relatively long compared to previous studies; therefore, several improvements were recommended, including eliminating unnecessary work elements, thoroughly maintaining the tools in the RMU, and placing a bucket in the outlet hole when changing sacks to reduce the time to collect scattered rice. In addition, the elements of rice sorting can be eliminated in the rice packaging process. Other recommendations include improving the working environment by encouraging workers to wear masks during rice milling.
