Abstract

Penelitian yang dilakukan adalah rancang bangun alat peraga praktikum berupa modul kontrol level air pada tandon dan bak. Output berupa pompa air dan solenoid valve. Pompa digunakan untuk mengalirkan air dari sumur ke tandon sedangkan solenoid valve digunakan untuk mengalirkan air dari tandon ke bak. Kerja pompa di pengaruhi level air di sumur dan tandon, kondisi awal sumur penuh (sensor level air sumur on) dan tandon kosong (sensor level atas dan bawah tandon off). Pada kondisi ini pompa bekerja beberapa saat kemudian sensor level bawah tandon on dan pompa masih bekerja. Pompa berhenti bekerja saat sensor level atas tandon berubah menjadi on (tandon penuh). Apabila tandon kembali kosong maka pompa akan kembali bekerja. Jika suatu saat sumur kering (sensor level air sumur off) maka pompa tidak akan bekerja, pompa akan bekerja kembali jika sumur kembali penuh. Kerja selenoid valve hanya dipengaruhi kondisi level air di bak saja. Saat bak kosong (Sensor level air bak off), selenoid valve (SV) akan bekerja. Ketika bak penuh (sensor level air bak on) selenoid valve (SV) akan berhenti bekerja. Sensor level air disumur dan bak digunakan mercury switch yang dimasukkan pelampung, untuk sensor level air tendon digunakan proximity capasitive.

Abstract

In the transition from the dry season to the rainy season, betta fish breeders are particularly affected. Betta fish cubs are prone to death. Betta fish fry are betta fish children after 1 to 7 days. The feedstock of betta fish cubs, namely water fleas, is greatly reduced due to overflowing water. Unstable temperature attacks the body resistance of betta fish cubs. This study designed and made a conditioning device for the growth of betta fish fry using PLC Zelio SR3B261BD and NodeMCU ESP8266.  Features of the tool consist of making artemia feed, distributing artemia feed, telling breeders to mix feed, controlling, and monitoring the temperature of the pond water. The results of the study showed that the device can work to hatch artemia eggs, distribute artemia to fry, notify farmers via telegram to mix feed, monitor the temperature, and maintain the temperature of the pond water in the range of 24?C - 27?C. The difference with previous fish farming research, this research adds a feature of making betta fish feed through the process of hatching artemia eggs.

Abstract

Bottle filling, closing, and labellingmachine control and monitoring tool using Programmable Logic Controller (PLC) and Human-Machine Interface (HMI). This tool is designed to optimize the production process in the bottled beverage industry,with dimensions of 200 cm × 70 cm × 100 cm. The conveyor transports bottles through the filling, capping, and labeling units. In each unit, sensors are installed to detect the presence of bottles. Bottle liquid volume is determined through time settings inputted through the HMI,and the filling is performed by a water pump. After filling, bottles are capped and tightened mechanically using an air impact system. Labeling is handled by two DC motors which unroll the label and rotate the bottle, ensuringthe label adheres evenlyto all sides of the bottle. The number of bottles produced is calculated using a capacitive proximity sensor and displayed on the HMI. Testing results show that the system effectivelycontrols and monitors the bottle filling, capping, and labeling process viaPLC and HMI. Based on the test results on the bottle filling unit, the system can fill water into the bottle with a maximum percentage error of 0.5% on a 1000 ml volume bottle. In the capping unit, the success rate achieved is 70%, while the success rate in the bottle labeling unit is 80%.

Abstract

The problem of waste in densely populated areas is a serious challenge that requires systematic and sustainable handling. The formulation of the problem in this study is how to design and build an automatic waste bin monitoring system based on LoRaWAN that has the ability to send data in real-time to the Antares platform. This study aims to design and build an automatic waste bin monitoring system that is able to provide information using the LoraWan architecture with the Antares platform. This system uses a number of ultrasonic sensors to detect waste volume and a number of limit switches to monitor the position of the trash bin lid. The LoRa module is used as a long-distance wireless data communication medium, while the Antares platform acts as a cloud-based data storage and presenter that can be accessed via a web dashboard. The system prototype was tested under various conditions. The aim is to evaluate sensor reliability, data transmission stability, and efficiency in power usage. The test results can monitor with a percentage of successful data transmission of 68% and experience errors or failures of 32%. In short, this monitoring system can be an efficient solution in supporting intelligent waste management based on the Internet of Things (IoT) and is fully feasible to be implemented in urban environments as part of the implementation of the smart city concept.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) in the food processing sector play a strategic role in supporting local economies but often face limitations in production technology and packaging systems. Griya Bandeng Sukati is a milkfish processing MSME in Semarang with promising products, yet its production process relies on manual seasoning preparation and conventional packaging. Manual seasoning requires considerable time and labor while producing inconsistent quality. In addition, non-vacuum packaging limits product shelf life and market expansion. This community service program aims to improve production performance and product shelf life through the application of appropriate technology in the form of a food chopper and a vacuum sealer. The implementation method includes problem identification, equipment procurement and testing, training on operation and maintenance, and continuous mentoring and evaluation. The results indicate that the food chopper significantly improves production efficiency and seasoning consistency, while the vacuum sealer enhances packaging quality and extends shelf life. Training and mentoring enable the partner to operate the equipment independently. Overall, the program positively impacts productivity, product quality, and MSME competitiveness.
