Abstract

Pertumbuhan penduduk meningkatkan permintaan sayuran segar, mendorong adopsi teknologi hidroponik yang menanam tanaman tanpa tanah menggunakan larutan nutrisi. Sistem ini meningkatkan produktivitas di lahan sempit dan menambah nilai estetika, serta menghindari penggunaan pestisida. Namun, pengaturan parameter seperti pH, oksigen, dan suhu diperlukan untuk menjaga pertumbuhan tanaman, terutama di lingkungan ekstrem seperti Semarang. Kegiatan pengabdian  mengimplementasikan teknologi IoT dalam sistem hidroponik apung di Nurusunnah Farm, Semarang. Teknologi ini memungkinkan pemantauan dan pengendalian parameter secara real-time, mengurangi beban kerja manual dan meningkatkan efisiensi serta produktivitas tanaman selada keriting. Kegiatan ini mencakup survei, perancangan, instalasi, pelatihan, dan evaluasi. Teknologi mampu melakukan pemantauan dan pengendalian parameter secara real-time, mengurangi beban kerja manual dan diharapkan meningkatkan produktivitas tanaman selada keriting. Hasil implementasi menunjukkan sistem yang dibuat dapat berjalan secara otomatis menggunakan teknologi IoT sehingga meningkatkan efisiensi pengelolaan kebun sekaligus mengurangi ketergantungan pada intervensi manual.

Abstract

Proportional Integral Derivative (PID) is a control system that combines proportional, integral, and derivative elements. PID control is often used in industrial machines. One of these machines is a 3-phase motor. Another important component in the industrial world is the Programmable Logic Controller (PLC) which is usually paired with an interface tool, namely HMI. The importance of a deep understanding of PID, PLC, HMI, and 3-phase motors is very important for students to be better prepared to face the real world of work. The application of the PID controller module using PLC as a learning tool at the Semarang State Polytechnic is still lacking, one of the reasons being the availability of PID controller modules that are inadequate. This study aims to design a PID controller module using PLC on a 3-phase motor. The creation of this practical module uses Omron HMI as a monitor in controlling 3-phase motor movements. Push buttons and switches are used as input components. Omron CP1E PLC is used as a processing component according to motor movement. The encoder is used to read the motor speed with an output in the form of a square signal which will be the feedback input read by the PLC. The inverter is used as a 3-phase induction motor driver. Buzzer and lights are used as indicators in controlling 3-phase motors. 3-phase induction motors are the main output components in this PID system. The power supply is used as a voltage source for the PLC so that the power supply must always be connected to a 220 VAC source. MCB is used as a protection system on the module.

Abstract

Public awareness of healthy lifestyles has increased the demand for fresh vegetables. However, limited land availability due to population growth poses a challenge for agricultural production. Hydroponics offers a solution without requiring large areas of land, yet its success depends heavily on controlling environmental parameters such as pH, temperature, and nutrients. This community service project aimed to implement smart greenhouse technology based on the Internet of Things (IoT) powered by renewable energy (RE) for curly lettuce cultivation at Nurus Sunnah Farm, Semarang City. The implementation stages included site surveys, system design and fabrication, installation, training, mentoring, and sustainability evaluation. The developed system utilized solar panels as an energy source and was equipped with three types of sensors (pH, TDS, temperature/humidity) integrated with ESP32 and an online monitoring platform. The results showed that the system was able to monitor and control hydroponic parameters in real time, with a pH sensor reading error of 0.0231 and a TDS sensor error of 0.0116. This innovation facilitates the management of nutrients, pH, and temperature, while reducing dependence on electricity from the national grid. The application of this technology has proven to enhance management efficiency, potentially maximize crop productivity, and support sustainable agriculture based on renewable energy

Abstract

The spread of the COVID-19 virus has occurred exponentially, necessitating advanced search technologies that provide accurate information. The primary challenge in searching for COVID-19 related information involves the diversity and rapid changes in data, as well as the need to understand specific medical contexts. Unstructured information sources, such as research articles, news reports, and social media discussions, add complexity to retrieving relevant and up-to-date information. As the volume of data and information related to the COVID-19 pandemic increases, there is a pressing need for effective and accurate information retrieval systems. Transformer architecture, known for its capabilities in natural language processing and managing complex contexts, offers great potential to enhance search quality in the healthcare domain. BERT is a deep learning model that performs searches based on specific queries, with search results sorted accordingly. The ranking process uses BERT architecture to compare the performance of transformer encoders, specifically between bi-encoders and cross-encoders. A bi- encoder is an architecture where two separate encoders process two different inputs, such as queries and documents. In contrast, a cross-encoder processes two texts simultaneously using a single encoder, allowing the model to capture contextual interactions between them. Research indicates that cross-encoder performance is significantly better than bi-encoder for cases with relatively small data sets. Evaluation results show that the NDCG score for bi-encoder is 0.89, while for cross-encoder it is 0.9. The mAP score for bi-encoder is 0.7, and for cross-encoder, it is 0.89. Both bi-encoder and cross-encoder achieved an MRR score of 1.0.

Abstract

This community service activity aims to help the ornamental plant business at "Surya Nursery," located in Pedalangan Village, Semarang, overcome plant care constraints due to limited time and human resources. The technology applied is an Arduino UNO-based automatic plant waterer equipped with a webcam for real-time monitoring in the business environment. The watering tool consists of 5 sprinklers that can rotate 360 degrees for an area of 200 square meters and can operate automatically or manually depending on the needs of the partner.Through this program, the team provides training and assistance to business partners, starting from device installation, system use, and maintenance of the technology applied. This system is expected to increase time efficiency, reduce water consumption, and maintain plant quality consistently.The results of this activity show that the tool can operate well, and partners feel the benefits in the form of increased productivity and reduced daily workload. The technology applied also opens up opportunities for "Surya Nursery" to increase competitiveness in the ornamental plant market. With this program, it is hoped that similar technology can be adopted by other small and medium enterprises in the agricultural sector.

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%.
