Abstract

Hidroponik merupakan budidaya pertanian yang tidak menggunakan tanah sebagai medianya. Kelebihan dalam bercocok tanam menggunakan media non tanah adalah salah satu cara penghematan lahan dan juga tidak memakan banyak biaya. Untuk kelemahan nya sendiri adalah perlu nya ketelitian tinggi. Hidroponik Hanza Farm menggunakan jenis hidroponik dengan metode Nutrifit Film Technique (NFT) di lahan terbuka. Hidroponik di lahan terbuka menimbul permasalahan yang lebih kompleks dari pada jenis hidroponik pada green house, namun dari sisi investasi lebih menguntungkan. Belum ada penerapan teknologi, baik konvensional maupun otomastis pada hidroponik mitra. Semuanya masih dikontrol secara konvensional oleh manusia. Pengendalian level air pada tandon dan sirkulasi air hidroponik masih menggunakan tenaga manusia, yang terkadang terjadi human error. Terbuangnya nutrisi pada saat kondisi hujan, karena air tandon yang sudah di isi dengan nutrisi menjadi tumpah karena tambahan air hujan.  Tumbuhan hidroponik menjadi layu dan kering akibat sirkulasi air yang tidak terkontrol. Untuk mengatasi masalah tersebut, maka diterapkan teknologi sistem otomatis. Pada pengabdian ini difokuskan pada masalah kontrol level air pada tandon nutrisi hidroponik. Sistem kontrol dan monitoring level air dibangun berbasis Internet of Things (IoT) menggunakan aplikasi telegram. Perangkat yang digunakan untuk mengukur level air berupa sensor level swicth. Data yang dibaca sensor kemudian dikirimkan ke NodeMCU ESP8266. NodeMCU akan mengolah data dan mengontrol on/off dari pompa, kemudian data juga dikirim ke telegram user menggunakan internet. Sehingga user dapat memonitoring dan mengontrol level air dari jarak jauh. Berdasarkan hasil pengujian yang telah dilakukan terhadap alat pendeteksi  banjir ini dapat ditarik kesimpulan bahwa, perangkat dapat mengukur ketinggian sebagaimana fungsinya, sensor jarak mampu mengukur ketinggian air dengan tingkat error -3 cm diatas jarak 150 cm dan rata-rata delay pengiriman data dari telegram ke Hidroponik adalah 3 detik. Dengan penerapan alat ini petani lebih mudah untuk memonitoring kondisi cuaca dan level air dari jarak jauh. Selain memonitoring alat ini juga dapat dikendalikan untuk mengaktifkan dan mengnonaktifkan pompa air.

Abstract

This research implements and compares two deep learning architectures, Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU), for predicting the stock price of Bank Rakyat Indonesia (BRI) using historical data from February 2023 to October 2024. Through systematic hyperparameter tuning and comprehensive evaluation, the study finds that GRU consistently outperforms LSTM across all regression metrics, with a 10.7% improvement in R² and an 18.5% reduction in MAPE. The optimal GRU configuration (100 units, 100 epochs, batch size 32, learning rate 0.001) achieves an MSE of 6517.5 and MAPE of 1.3764%. Visual analysis confirms GRU's superior ability to capture stock price fluctuations and adapt more quickly to trend changes. The simpler architecture of GRU with fewer parameters proves more effective for handling the high-noise characteristics and varying volatility of stock price data. While both models face challenges in predicting extreme market events, GRU demonstrates better resilience and faster recovery after such occurrences. This research contributes to the understanding of recurrent neural network applications in financial time series forecasting and provides practical insights for developing more accurate stock price prediction systems.

Abstract

Oil palm plantations in Indonesia demand efficient weed control methods, particularly for large-scale operations in remote areas. Manual pesticide sprayers are still commonly used, but they require high labor, long operating time, and are not energy-efficient. This study presents the design and development of a solar-powered pesticide sprayer using the ADDIE method—Analysis, Design, Development, Implementation, and Evaluation. The prototype consists of a 50 Wp monocrystalline solar panel, two 12V 24Ah VRLA batteries, a DC pump with variable pressure levels, and an Automatic Transfer Switch (ATS) for alternating battery use. The system is mounted on a frame suitable for motorcycle transport to improve field mobility and adaptability in plantation environments. Development followed all ADDIE phases and was validated through real-world field testing. Results showed a 75% reduction in spraying time—from 8 hours (manual) to 2 hours—with a maximum pressure of 70 PSI and a spray reach of 3.5 meters. The ATS allowed uninterrupted operation under varying sunlight conditions. This design offers greater energy efficiency, continuous usability, and flexible deployment compared to similar systems. The findings demonstrate the feasibility of applying solar energy to support sustainable weed management in off-grid agricultural settings, highlighting its potential for broader agricultural mechanization.

Abstract

The palm oil industry has a significant impact on the regional and national economy, generating employment, especially for farmers. Crude palm oil (CPO) can be processed into edible oil, cosmetics, and biofuels, making it a strategic commodity in global trade. However, this industry also produces abundant solid and liquid waste, such as shells, fibers, and empty fruit bunches. Factory waste must be managed and processed to prevent environmental pollution. Poor waste management can lead to various environmental problems, necessitating effective and sustainable management strategies. This type of solid waste has the potential to be used as an alternative energy source and raw material for value-added products. The objective was to determine the utilization of palm oil solid waste and its percentage, as an effort to optimize industrial waste management. The methods used included direct observation of the processing and utilization of solid waste at the factory, collection of production data, and a review of relevant literature. The results showed that empty fruit bunches are used as compost and mulch in plantations, shells are used as boiler fuel to generate steam energy, and fiber is used as supplementary fuel. According to the literature review, this solid waste still has potential for further development, such as the production of briquettes, pellets, and biomass-based activated carbon. Optimizing the utilization of palm oil solid waste can increase the energy efficiency of factories and reduce the volume of waste.
