Sistem Komunikasi Mikrokontroler dan PLC Berbasis Komunikasi Serial Host Link dan Protokol C-Command RS232
The communication between microcontrollers and PLC has become an important technology development that needs to be enhanced. One of the reasons for the communication between these two devices is to facilitate the input process of data or information from sensors, which are responsible for detecting or measuring specific parameters. Not all sensors can be directly read by PLC, as some sensors have their own communication protocols or specific libraries that are not directly supported by PLC. Microcontrollers are often used as intermediaries between sensors and PLC. Microcontrollers can read sensor data and then convert it into a format that can be understood by PLC. Microcontrollers can perform flat processing tasks such as conversion and status evaluation to provide more relevant data, and then send this data to the PLC through a compatible communication protocol. In this study, the communication protocol used is the Host Link serial communication using the C-mode Command method. The communication testing conducted using 10 different data samples resulted in accurate values with an error percentage of 0%
Evaluasi Efisensi Riser Untuk Bentuk Riser Samping yang Berbeda Menggunakan Metode Simulasi Casting
As the solidification reaches the hot spot area, no molten metal remains and shrinkage is formed. To anticipate the shrinkage, a riser is added to the casting system. An optimal riser design would produce free shrinkage components. One of the factors that affect riser efficiency is the riser shape. This study aims to find the most efficient side riser shape by using simulation software. The riser shape of tubes, tubes with a half sphere on top, hemispheres, conical tubes, tubes with an oval cross-section, and cubes are used in this experiment, with the volume of all risers kept constant. The most efficient shape of the riser is the tube. The tube riser produces a larger modulus. The tube riser generated directional solidification. The same pattern can be seen in the niyama criteria and solidification temperature, where the tube riser has a more continuous pattern compared to other riser shapes.
 
Pemanfaatan Pepaya sebagai Biostarter dalam Pengomposan Limbah Ikan dan Daun Mangrove Menggunakan Larva Black Soldier Fly
Fish waste generated from industrial activities in coastal communities has the potential to cause bad odors and pollute the environment. Falling mangrove leaves also contribute to waste in coastal areas because there are mangrove forests. This can pollute the environment so that fish waste and mangrove leaves can be processed through the composting method. Composting with BSF larvae can provide double benefits, namely reducing waste and producing larval feces that plants need. Papaya fruit waste that is no longer suitable for consumption can be used as a biostarter to speed up the decomposition process. The research variable was the use of 200 ml/kg papaya fruit biostarter. Variation in composition 100% mangrove leaves, 50% mangrove leaves; 50% fish waste, 70% mangrove leaves; 30% fish waste. Moisture content, temperature, pH, C/N, phosphorus, and potassium in several variations of this study met the quality of compost based on SNI 19-7030-2004. Based on MANOVA statistical analysis, variations in composition and type of biostarter influence larval biomass, feed consumption, and waste reduction index. Based on the quality of the compost, the best variation in this study was the composition of 50% fish waste compost and 50% mangrove leaves without the use of a biostarter
Analisis dan Model Dispersi Emisi Udara di TPA Klotok, Kediri: Dispersion Analysis and Model of Air Emissionin Klotok Landfill, Kediri
Klotok landfill is a final waste processing site in the City of Kediri that has been operating since 1992 to manage waste in the Kediri City and its surroundings. Waste management activities at the Klotok TPA generate emissions from the waste pile and heavy equipment activities. This study aims to determine the air quality at the Klotok Landfill through direct measurements to obtain results with a more accurate approach. The measurement results will then be modeled with AERMOD software to determine the distribution of these pollutants to the area around the TPA. In this study, air quality measurements were carried out at three points in the Klotok TPA to determine the level of pollution that occurred. Air quality is measured directly using a High Volume Air Sampler (HVAS), Impinger, and Sound Level Meter. Air pollutant parameters measured included Nitrogen Dioxide (NO2), Total Suspended Particulate (TSP), Sulfur Dioxide (SO2), Oxidants (O3), Carbon Monoxide (CO), Lead (Pb), Non-Methane Hydrocarbons (NMHC), Particulate Matter 2.5 (PM2.5), PM10, Ammonia (NH3), and noise. The measurement results show that the CO parameter exceeds theambient air quality standards of PP No. 22 Year 2021 at the weighbridge and the landfill 3 with values of 13,750 and 18,750 µg/Nm3 respectively,while other parameters still meet the quality standard. The model with AERMOD software shows the dispersion of CO nearby the landfill area occurs quickly so that since the first 100 meters the CO concentration has been dispersed to below 10 µg/Nm3. CO concentrations at a distance of more than 1 km from the Klotok TPA are generally below 1 µg/Nm3
