Abstract

Research on design and fabrication of temperature and humidity measuring devices based on the ATMega 16A-PU microcontroller module can be realized directly on the FFB heating system. Temperature and humidity measuring devices consist of DC power supply, voltage follower, SHT11 sensor module, LM35 Waterproof sensor, 20x4 character LCD and ATMega 16A-PU microcontroller module. Whereas the FFB heating system consists of steam, boiler, air control room, and chamber. The system can be realized by placing the LM35 Waterproof sensor inside the air control room and the SHT11 sensor module inside the chamber. This system is also equipped with data acquisition software using the Delphi 7.0 program to display measured data in real-time and save it to Excel and the database. Tests carried out by flowing using wet steam generated from the boiler into the air control room and chamber. The average error value of reading the standard gauge with a gauge that has been made for the LM35 Waterproof sensor with a measurement range of 20-90ºC is 1.22ºC. As for the SHT11 sensor module, the average error value of readings with a measurement range of 20-90ºC and 40-90% is 1.04°C and 4.04%

Abstract

Cassava chips are a type of snack that is fried and prone to rancidity if stored for a while. Cassava chips are added to the material that can adsorb gases, such as oxygen and water vapor, to reduce the occurrence of rancidity using a sachet-shaped adsorbent material. Activated charcoal is one of the gas adsorbents. Activated charcoal used is activated charcoal made from oil palm shells and activated with 20% phosphoric acid. This study aims to analyze the decrease in the quality of cassava chips with an active packaging system during storage for 30 days at 45oC. A total of 30 g cassava chips were packed with a standing pouch in polypropylene type and added activated charcoal from oil palm shells activated by 20% phosphoric acid as much as 1.5 g or 0.75 g which was packed with metalized aluminum plastic or LDPE plastic in the form of sachets. Storage of cassava chips with an active packaging system for 30 days and stored at a temperature of 45oC with a humidity of about 60% and observations are every 3 days in aroma and texture scoring test, moisture content, free fatty acid levels, fat content, and peroxide number. During storage from day 0 to day 30, the cassava chips have decreased the quality of the aroma from typical cassava chips to slightly rancid and the texture from crisp to somewhat not crisp. Moisture content, free fatty acid levels, and peroxide numbers during storage have increased. The fat content has decreasedduring storage. Based on this, cassava chips with the addition of 1.5 g activated charcoal and packaged with metalized aluminum plastic become the best active packaging system.

Abstract

Forest and land fire disasters in Indonesia have started to become a hot topic of discussion in the last decade. Not only attract domestic attention, international organizations also paid attention to the incidence of this wildfire. The widespread wildfire is considered a serious threat by Indonesia government. This disaster completely has a negative impact on economy, health, environment, social and cultural aspect. Indonesia has received a lot of criticism in its efforts to control the wildfire disaster. Indonesia is required to present the right policy formulation to control this disaster. This study aims to provide policy alternatives that are implementable and effective in controlling wildfire disasters in Indonesia. The dynamic systems modeling approach was used in this study with a mean absolute percentage error of 8.65%. It is predicted that there will be another spike of hotspots in 2023. Suppressive and preventive strategies have been used as leveraging variables in controlling fire disasters. The combination of these two strategies with the dominance of a preventive strategy has proved to be quite effective in controlling the chance of catastrophic forest and land wildfires in the next few years.
