Abstract— The process of processing household waste into biogas is carried out using fermentation technology. Fermentation technology is the process of decomposition of organic compounds to produce energy and changes in the substrate become new products by microbes. In addition, the fermentation technique that has been done by fermenting household waste produces methane gas content (CH?). To process household waste into biogas is to use biodigester. Biogester is a closed space that is used for the waste fermentation process which is assisted by microbes. Using a biodigester is expected to accelerate the fermentation process of household waste into alternative biogas materials because of the airtight biodigester state. A temperature and pressure data logger tool is designed on smart biogas household waste using the MPX5500DP sensor. The MPX5500DP sensor will detect the amount of gas pressure from the biogas results because the range of readings from this sensor is in accordance with what is needed, while the DHT22 sensor uses a large temperature reading because the temperature in the biodigester is not too large between 28?C - 40?C. From the results of reading the temperature and pressure values, the data will be processed by the Arduino Uno Microcontroller and stored data by the data logger. Based on the test results, the temperature measurement error readings of 0.81%, while for the pressure measurement of about 3.5%.

Lemuru fish is a typical Sumbawa dish made from many types of fish and processed through various processes such as salting, salting and drying. The purpose of this research is the time and temperature of the drying process. The independent variables are: variations in temperature (50ºC, 60ºC, 70ºC) and time (180 minutes, 240 minutes, 300 minutes). After analysis, the following conclusions can be drawn. The drying speed is 180 minutes at 70°C. The highest drying speed was 0.98 g/minute, while the lowest was 300 minutes at 50 °C and a value of 0.56 g/minute. The air content temperature is 60⁰C and 70⁰C according to the quality standard for dried fish (SNI 82732016). Temperature 50 ⁰C 240 and time 300 minutes air content 32.67 n 28.33%. Drying time of 50% temperature 180 minutes gives 8.87% efficiency at lowest temperature 70ºC 300 minutes gives 3.64% The lowest material consumption is 180 minutes at 50ºC gives a value of 0.087 kg, the highest fuel consumption at 70ºC gets a value of 0.31 kg
