Abstract

This study aims to develop an orange harvest revenue prediction system that integrates color-based sorting technology and rule-based data analysis. With the increasing demand for oranges in Indonesia, efficiency and accuracy in the sorting process and revenue prediction are of utmost importance. The developed system utilizes the TCS34725 color sensor to classify oranges based on maturity level and employs a rule-based method to predict harvest revenue based on sorting data and external factors such as weather conditions and market prices. Field testing results indicate that this system significantly improves sorting accuracy and provides accurate revenue predictions. The implementation of this technology in the orange industry offers potential enhancements in operational efficiency and profitability. This research contributes importantly to the application of sensor technology and data analysis in agriculture, demonstrating how technological innovation can help address challenges in the orange industry and the broader agricultural sector.

Abstract

Sentiment analysis is conducted to measure public opinion tendencies towards ongoing or past events. One of the cases analyzed in this study is Online Loans, commonly known as "Pinjol" in Indonesian. The research data regarding Online Loans was collected from the Twitter social media platform using the keyword "Pinjaman Online." The analysis method employed in this study is Naïve Bayes. Prior to the sentiment analysis process, text data was obtained through crawling from the Twitter API using the Rapidminer application. The data was then subjected to text pre-processing. Subsequently, the data underwent TF-IDF weighting. The results of this research demonstrate the tendencies of positive and negative sentiment conflicts within each tweet discussed by Twitter users regarding Online Loans. The conclusion drawn from the sentiment analysis using the Naïve Bayes classification algorithm with data obtained from Twitter concerning Online Loans is as follows: Out of the 2931 data used, after undergoing text pre-processing, a total of 2912 data were available. Among them, negative sentiment accounted for 68.61% with 1998 data, while positive sentiment accounted for 31.39% with 914 data. The sentiment analysis of Twitter users regarding Online Loans achieved an accuracy rate of 80%.

Abstract

Tujuan dari pengabdian ini adalah untuk mengimplementasikan aplikasi pembukuan berbasis Android yang dapat memperbaiki sistem manajemen keuangan Motorun Indonesia. Metode yang digunakan meliputi sosialisasi, pelatihan, dan pendampingan dalam penggunaan aplikasi digital. Evaluasi dilakukan melalui angket dan wawancara pasca-kegiatan untuk mengukur efektivitas aplikasi dalam meningkatkan kemampuan teknis (hardskill) mitra. Hasil menunjukkan peningkatan dalam kemampuan mitra mengelola pembukuan digital, dengan efisiensi waktu pencatatan transaksi meningkat. Simpulan dari kegiatan ini telah tercapai peningkatan kemampuan teknis mitra sekitar 75% dalam penggunaan sistem pembukuan berbasis aplikasi android. Selain itu penyajian laporan keuangan harian dan bulanan dihasilkan secara otomatis, memudahkan pemilik usaha dalam memantau arus kas tanpa perlu melakukan perhitungan manual. Sehingga meningkatkan nilai ekonomis dan pengambilan keputusan bisnis yang lebih baik

Abstract

This study, we quantify how WSN topology shapes QoS for IoT water-quality monitoring and derive deployment rules. Five topologies (Hybrid Star–Mesh, Cluster Tree, Full Mesh, Ring, ZigBee Star; 20 nodes) were simulated in NS-3 for 10 independent runs with random seeds. Our mathematical contribution is a compact QoS model set—latency LLL, packet-loss PlossP_{\text{loss}} Ploss, bandwidth usage UBU_BUB, and throughput TTT—used to compare topologies and compute relative/absolute improvements. Statistics report mean±SD with 95% confidence intervals from Student’s t-distribution; pairwise Mann–Whitney tests with Benjamini–Hochberg FDR control (α=0.05) yield compact-letter displays; Cliff’s δ quantifies effect sizes. Results: Hybrid Star–Mesh minimizes latency/loss while maximizing throughput; Ring is consistently inferior; Cluster Tree and ZigBee Star are mid-range; Full Mesh trades redundancy for delay and bandwidth. These models produce actionable guidance for aquaculture (real-time dissolved-oxygen) and urban drinking-water safety, and motivate multi-objective optimization (latency–throughput–energy) toward Pareto-optimal designs.
