Abstract

Chili cultivation requires timely irrigation to maintain soil moisture, yet manual watering is inefficient and difficult to supervise remotely. This paper proposes an IoT-based irrigation system integrating a Telegram bot and a web dashboard for real-time monitoring and control. A soil-moisture sensor provides input to an ESP32 microcontroller, which drives a relay-operated pump using a threshold rule (ON when moisture <30%) and supports manual override via Telegram commands. Sensor readings are logged to Firebase and visualized on a Flask-based dashboard, which features moisture trend graphs. Telegram delivers notifications and supports command-based interaction. Experiments demonstrate an average accuracy of 98,57% and precision of 99,93% compared to a reference meter. End-to-end tests confirm a 0% delivery error, a Telegram notification latency of 1,0–1,8 seconds, and a pump response time of 5,3–5,9 seconds, demonstrating effective automation with practical remote supervision.

Abstract

Meningkatnya permintaan energi global mendorong pengembangan bahan bakar alternatif berkelanjutan dengan karakteristik pembakaran yang kompetitif terhadap petrodiesel. Penelitian ini mengkaji fenomena termofluida dinamis pembakaran droplet campuran petrodiesel dan biodiesel minyak kesambi, baik tanpa maupun dengan penambahan katalis nanopartikel TiO₂ 100 ppm. Komposisi sampel bahan bakar yang digunakan terdiri dari B0, B10, B20, B30, B40, dan B100, serta masing-masing komposisi dengan penambahan TiO₂. Parameter yang dianalisis meliputi penundaan penyalaan, durasi pembakaran, tinggi nyala api, suhu optimal, dan visualisasi nyala api. Hasil penelitian menunjukkan bahwa peningkatan fraksi biodiesel menghasilkan durasi pembakaran yang lebih lama hingga 6,83 detik pada B100 dan penurunan suhu puncak sebesar 734,76°C, dibandingkan dengan B0 yang memiliki durasi pembakaran selama 3,22 detik dan suhu puncak sebesar 794,54°C. Penambahan TiO₂ secara konsisten meningkatkan kinerja pembakaran, ditunjukkan oleh suhu puncak yang lebih tinggi hingga 821,76°C pada B0+TiO₂, penundaan pengapian yang lebih singkat, dan nyala api yang lebih stabil. Tinggi nyala api tertinggi teramati pada B0+TiO2 sebesar 53,79 mm dan terendah pada B100 sebesar 40,87 mm. Selain itu, penundaan pengapian tertinggi terjadi pada komposisi B100 sebesar 7,95 detik, sementara terendah terjadi pada komposisi B0+TiO2 sebesar 1,65 detik. Hal ini menunjukkan adanya hubungan antara komposisi bahan bakar dan intensitas pembakaran.

Abstract

Accurate forecasting of rice output is essential for improving regional food security planning, particularly in East Java Province, which serves as a major national rice granary. This study develops a Long Short-Term Memory (LSTM) model to predict rice production using monthly data on production and harvested area from 2018 to 2024. The methodology includes data preprocessing, normalization, sequence construction with a sliding window, training of a multivariate LSTM model, and performance evaluation using mean absolute error (MAE), root mean square error (RMSE), and mean absolute percentage error (MAPE). Results show that the LSTM model achieves superior predictive accuracy, with an MAE of 95,030.16, RMSE of 120,229.01, and MAPE of 16.64%, significantly outperforming baseline Moving Average and Linear Regression models. While the model effectively captures seasonal production trends, some inaccuracies remain during periods of anomalous production values. These findings suggest that the LSTM model is effective for projecting rice production and may provide a foundation for early warning systems and regional food distribution strategies. Further improvements could be realized by integrating climate variables or adopting a hybrid model architecture to enhance predictive precision.

Abstract

This community service program aims to improve the marketing performance of a cassava rengginang micro, small, and medium enterprise (MSME) located in Banasare Village, Rubaru District, which faces limitations in digital marketing capabilities and has not yet utilized artificial intelligence (AI) technology. The partner MSME relies on conventional marketing methods, resulting in limited market reach and low promotional effectiveness. The method employed in this program integrates structured training with hands-on assistance in the implementation of artificial intelligence for marketing purposes. The stages include partner needs analysis through observation and interviews, AI-based marketing training focusing on content creation, direct assistance in applying AI to digital marketing and customer services, and evaluation through a comparison of conditions before and after the program. The results indicate a significant improvement in the partner’s capacity to utilize AI for marketing activities. After participating in the program, the MSME was able to independently create structured digital promotional content using AI tools and implement simple chatbot-based customer service. These changes contributed to more effective promotion, improved service efficiency, and broader market reach compared to the initial condition. The outputs of this community service activity include increased digital marketing skills of the partner MSME, the adoption of AI-based marketing practices, and the development of a replicable training and assistance model suitable for traditional food MSMEs in rural areas. This program demonstrates that artificial intelligence can be applied in a simple and practical manner to support the digital transformation and competitiveness of rural MSMEs.

Abstract

Dairy farmers in Kandang Tepus Village, Senduro District, Lumajang Regency, faced challenges in feed preparation because the processes of chopping forage and mixing feed were still performed manually. This resulted in lengthy feeding preparation times and required significant physical effort. This community service initiative aimed to implement grass-chopping and feed-mixing machines in the feed preparation process while enhancing the partners' ability to operate and perform basic maintenance on the equipment. The activity employed a participatory and applied approach across five stages: identifying partner needs and issues; designing and fabricating the technology; testing and refinement; training and technology implementation; and mentoring, monitoring, and evaluation. Prior to the technology's implementation, forage chopping was done using sickles, and feed ingredients were mixed by hand. Following implementation, chopping was mechanized producing cut lengths of approximately 2 to 3 cm and feed mixing was carried out using a mechanical mixer. Interviews with the partners indicated that the technology reduced feed preparation time by approximately 30% compared to the previous manual method. Training and mentoring outcomes demonstrated that the partners were capable of operating the grass-chopping and feed-mixing machines and performing basic equipment maintenance. The introduction of these two machines transformed the feed preparation process from one dominated by manual labor into a more mechanized and structured operation. This initiative demonstrates that implementing grass-chopping and feed-mixing machines—complemented by training and mentoring can improve feed preparation efficiency and enhance the partners' capacity to utilize and maintain the technology.
