Abstract

Educating the community by conducting counselling, training and mentoring to farmer groups, as a form of supporting the food security programme in Kebumen district. Together with the Margo Raharjo farmer group in Jatiluhur village, Karanganyar sub-district, making organic boosters for rice plants. Participants involved in the service were members of the Margo Raharjo farmer group, and KKN students from Ma'arif Nahdlatul Ulama University Kebumen. Training and counselling activities are carried out so that farmers are not dependent on inorganic fertilisers while providing education on the importance of using organic materials in agriculture. This activity seeks to help overcome the problems that exist in the community, especially in the knowledge of organic fertiliser for rice plants. The use of organic boosters is not only environmentally friendly but also reduces the cost of purchasing booster products on the market which cost up to 230 thousand rupiah. Inorganic booster products are certainly very expensive and less environmentally friendly. Booster is a liquid organic fertiliser whose nutrients play a role in stimulating the generative growth of flowers and fruits. Increasing farmers' awareness of the dangers of continuous use of inorganic fertilisers encourages farmers to switch to the use of environmentally friendly organic fertilisers.  Organic booster made from fermented pineapple is one of the liquid organic fertilisers applied in the generative phase of plants, namely at the beginning of flowering and fruiting. After the practice of making organic booster, participants are expected to be able to independently or together with the group to follow up and apply the fertiliser to rice plants according to instructions and recommendations. Further testing and research is needed on organic boosters and making organic boosters from different materials and easily obtained in the surrounding environment.  From the results of this activity, the following conclusions were obtained: This activity can improve skills and increase knowledge or insight into the community about organic fertiliser to support increased agricultural productivity, The use of organic booster as one of the solutions to reduce the use of inorganic fertilisers to increase the productivity and quality of products from rice cultivation. Keywords: Organic Fertiliser, Liquid Organic Fertiliser, Vegetable Fungicide, Organic Rice

Abstract

Implementation of Occupational Safety and Health (K3) in construction projects is an effort to create a safe and healthy work environment, free from work accidents and work-related diseases. Based on the International Labor Organization (ILO) report in 2019, more than 395 million workers worldwide experienced non-fatal work injuries. In Indonesia, BPJS Employment reported 370,747 work accident cases in 2023, with an increase of 19.7% from the previous year. As many as 32.12% of these incidents were caused by not using personal protective equipment (APD), including safety helmets. This research aims to build a model through machine learning to automatically detect the use of safety helmets using the YOLOv8 algorithm. The YOLO algorithm is known to have good detection speed and is suitable for complex construction environments. The model evaluation results show that Average Precision reached 78% for all classes, 82% for the APD class, 72% for the non-APD class, and 80% for the non-safety class. The resulting precision value was 77.7% and the recall value was 60.7%, with a mAP (mean Average Precision) level reaching 68.9%. The model training time lasted 1 hour 7 minutes.

Abstract

The increasing need for quail farmers to identify diseases quickly and accurately, considering that many farmers do not have in-depth knowledge about the symptoms of diseases that may occur and the treatments that must be administered once the quails are infected. The lack of veterinarians also causes farmers to be anxious about handling diseases that affect quails. This research aims to develop an expert system that diagnoses quail diseases using the Naïve Bayes method. The methods applied in this study include collecting data on quail disease symptoms, processing data to transform categorical values into numerical ones, and implementing the Naive Bayes algorithm by dividing the dataset into training and testing data. The research results show that the developed model achieved an accuracy of 82.75% in diagnosing quail diseases. This accuracy is quite competitive compared to previous studies that used similar methods for other livestock with accuracy levels ranging from 60% to 90%. The system's performance evaluation using a confusion matrix and classification report indicates that the model can classify most cases correctly, although there are some prediction errors in certain classes. This shows that the effectiveness of the expert system in diagnosing quail diseases using the Naive Bayes method can provide a solution for farmers to recognize and address diseases earlier.

Abstract

Kebumen Regency, located on the southern coast of Java, faces a high disaster risk due to its position in a tectonic subduction zone that can trigger major earthquakes. The presence of the Sempor and Wadaslintang dams further increases vulnerability to potential failures during seismic events. This study identifies the need for a rapid and accurate disaster assessment system to strengthen preparedness and emergency response. To address this, we developed a web-based system that enables both communities and government officials to collect real-time data from affected areas. System development, functionality testing, and performance evaluation were conducted to assess its effectiveness. The results show that the system delivers timely and accurate data, enhances coordination, and improves community resilience. This system is expected to be an efficient solution for disaster management in Kebumen Regency.
