Abstract

Mushrooms are one of the most popular foods in Indonesia because of their high nutritional value. The form of processed food that currently has a good market share is snack food chips. This study aimed to calculate the value of the water absorption constant (k) and to predict the shelf life of oyster mushroom chips in polypropylene (PP) plastics at 0.03 mm, 0.05 mm, and 0.07 mm thickness, and stored at the storage room humidity (RH) variations of NaNO2 (63%), NaCl (75%), and KCl (84%). This study was repeated three times, resulting in a total of 12 units. The results of this study showed that the higher the RH at storage and the thinner the thickness of the packaging, the higher the water content by weight (Me) of the material and the greater the contents value of its water absorption rate. Under these conditions, the shorter the shelf life of the fungal chips. The values of Me and the constant k on the variation of packaging thickness and RH range respectively from 11.5 to 26.5 and 0.05 to 0.17. The oyster mushroom chips have a shelf life of up to 17 days at a storage RH of 63% and are packaged in 0.07 mm thick PP plastic. Keywords: Mushrooms, Polypropylene Plastic, and the Water Absorption Constant (k).

Abstract

Lampung Province is the largest producer of cassava in Indonesia. However, cassava production in Lampung has been declining over the past five years due to many farmers switching to other commodities due to the long harvesting period and unstable prices. This has resulted in a buildup of cassava stem waste, requiring innovation to manage this waste. Hence, the cassava stem chopper (Rabakong) was introduced. Rabakong has been developed by Agricultural Engineering (TEP) students from the University of Lampung, starting from TEP 1, TEP 2, TEP 3, TEP 4, and TEP 5. This research method involves modifying the frame of the previous version, redesigning the components to be modified using AutoCAD software, and then fabricating and collecting data after modification. The latest modified Rabakong machine underwent significant changes in the number of blades, which are fewer but arranged spirally for efficiency in chopping and space-saving. The working capacity has increased to 207 kg/hour at 1400 rpm. Waste material has decreased to 11.39%. Fuel consumption is 2.580 liters/hour. The percentage of finely chopped materials (<0.2 mm) is only 17.19%, while coarsely chopped materials (>0.5 cm) reach 51.41%, indicating that the latest version is more suitable for coarse results.. Keywords: Cassava Stems, Design, Efficiency, Modification.

Abstract

Cause of damage is improper or inappropriate packaging. Therefore this study aims to determine the optimal type of packaging damper in minimizing mechanical damage to the fruit. This research was conducted in February - April 2020 at the Laboratory of Bioprocess Engineering and Postharvest Handling, University of Lampung. This research was conducted by looking at the level of damage to the avocado when dropped manually and when vibrated mechanically with a vibrating table. In the manual experiment, one avocado is divided into four parts, each part will be treated with different absorbent materials in the form of straw, fibers, dried banana leaves and control with a thickness of 2cm damper which is then dropped from a height of 5 cm, 10 cm, and 15 cm. In mechanical testing using a packaging box measuring 29 cm long, 14 cm wide and 14 cm high. Each box contains 12 avocados arranged in 2 layers and then added with a damper with a thickness of 2 cm, each package is ventilated with a circle type with a diameter of 3 cm, 4 pieces on each right and left side of the package. The observed parameters were mechanical damage in the form of bruises, weight loss, and level of hardness test. The observed data obtained were processed using simple statistics with each data averaged and compared to the damage between the fruit that was dropped manually and vibrated with a vibrating table. The results showed that the fiber-absorbing agent treatment was more optimal in minimizing mechanical damage to avocado because the fibers had a lignin content of around 29.4%. Keywords: Avocado, Mechanical Damage, Silencer, Transportation Simulation.
