Abstract

North Aceh is a district with diverse geographical conditions, ranging from vast lowland areas in the north stretching from west to east, to mountainous areas in the south. The average altitude in North Aceh is 125 meters. The district covers an area of 2,694.66 km² with a population of 614,640 people in 2022. The issue of crime in North Aceh District has caused significant discomfort among the community. According to data from the Central Bureau of Statistics (BPS) of Aceh Province, the number of criminal cases increased from 6,651 cases in 2022 to 10,137 cases in 2023. Using the Fuzzy C-Means clustering method, the data was grouped into three clusters: cluster 1 represents safe areas, cluster 2 represents moderately vulnerable areas, and cluster 3 represents vulnerable areas. For ranking using the Borda method, the Dewantara Police Sector ranked first for the physical aspect, while the Muara Batu Police Sector ranked first for the item aspect. As for predictions using the LSTM model, almost all subdistricts achieved MAPE values below 20%, indicating that the LSTM model is quite effective in predicting crime-prone areas. For example, Baktiya District recorded a MAPE value of 15.85% for the physical aspect, while the best result was achieved by Simpang Keramat District for the item aspect with a MAPE value of 0.00%. However, in Syamtalira Bayu District, the item aspect reached a MAPE value of 20.07%. Although the MAPE value for the item aspect in Syamtalira Bayu is relatively high, it is still considered acceptable as it remains below 50%.

Abstract

This study aims to optimize algae biomass production by utilizing Palm Oil Mill Effluent (POME) as a nutrient source, employing Internet of Things (IoT) technology and Artificial Neural Networks (ANN) for predictive modeling and system control. POME, an organic waste from the palm oil industry, was used as an organic liquid fertilizer to enhance the efficiency and sustainability of algae cultivation. The system was designed to monitor and control key environmental parameters such as pH, temperature, salinity, and dissolved oxygen in real-time during a one-month trial in July 2024. ANN-based models were used to predict and adjust environmental conditions, leading to significant improvements in algae growth and resource efficiency. The results indicate that POME can serve as an effective and eco-friendly nutrient source, contributing to both reduced industrial waste and sustainable biomass production. This integrated approach supports circular economy principles and sustainability goals, with potential applications in bioresource production and waste management. Future research will focus on large-scale system testing, optimization for various algae species, and long-term sustainability assessment.

Abstract

Penelitian ini membandingkan kinerja protokol MQTT dan HTTP dalam sistem komunikasi Internet of Things (IoT), khususnya untuk pemantauan kualitas udara ruang kelas secara real-time. Evaluasi dilakukan menggunakan server virtual machine dengan spesifikasi identik, berdasarkan parameter seperti penggunaan CPU, waktu pengiriman pesan, dan tingkat kehilangan data. MQTT, sebagai protokol ringan dengan model publish-subscribe, menunjukkan kecepatan pengiriman pesan yang jauh lebih tinggi dibandingkan HTTP, terutama pada skenario dengan volume pesan yang besar. Namun, penggunaan CPU pada MQTT meningkat tajam seiring bertambahnya jumlah pesan, dan terjadi kehilangan data yang signifikan hingga 33,8% pada pengiriman 600.000 pesan. Sebaliknya, HTTP yang berbasis model request-response dengan mekanisme multi-proses, mampu menjaga keandalan pengiriman pesan hingga 100%, meskipun waktu pengirimannya jauh lebih lambat. Hasil penelitian ini menunjukkan bahwa MQTT lebih efisien untuk sistem yang membutuhkan kecepatan tinggi dan dapat mentoleransi sebagian kehilangan data, sementara HTTP lebih cocok untuk aplikasi yang menuntut keandalan tinggi dan akurasi data secara penuh. Temuan ini memberikan wawasan penting bagi pengembang dalam memilih protokol komunikasi yang sesuai berdasarkan kebutuhan sistem IoT dan skala implementasinya.

Abstract

The availability of oil palm fruits at the appropriate ripeness level is crucial to achieving optimal oil production. Farmers often struggle to accurately determine fruit ripeness, resulting in inconsistent quality and reduced efficiency. This study aims to develop a classification system to determine the ripeness level oil palm fruits using the K-Nerest Neighbor (K-NN) algorithm based on color features extracted from fruits image. Color is a key indicator of maturity and directly influences oil yield. The data was collected through image acquisition and direct observation at the Cot Girek Palm Oil Mill (PKS) of PTPN IV, Aceh Utara. Image preprocessing was carried out to enhance and nomalize the data before feature extraction. The extracted color features were then used to classify the fruits into ripe and unripe categories using the K-NN algorithm. The results show that K-NN successfully classifies the ripeness level of oil palm fruits with an accuracy of 72.80%. This system provides a recommendation for fruit feasibility before processing, helping reduce production losses caused by immature or overripe fruits. Overall, this research contributes to improving decision-making in the palm oil industry through the application of image processing of machine learning techniques.
