Abstract

Banteran village especially Danalaya halmet is located at the foot of Slamet mountain with the contours of the hilly villages so that the location of residential areas is higher than in the river around the village, as well as their water source. With these conditions, the pump installation built hidram that is the water pump hydropower that serves to pump the water to burst higher than the waterfall, so the clean water needs at Danalaya halmet can be met. Network hidram pump clean water from the new turns up at one point and has not spread to the rest of the villagers so that not all villagers can enjoy it and it is a problem that must be solved. Given the problems we plan to help villagers Danalaya in the water distribution network by making clean water and we want to raise the water higher so water can be channeled to the whole house of the villagers. We use additional solar-powered pump (Green Infrastructure), so that the location of the water tank and the higher availability of clean water dealer network along with the water meter, it is expected the entire village can enjoy the clean water has been channeled later. PDAM of village also formed to regulate water usage recorded by the water meter so that the operational costs of water usage can be adjusted by the amount of water consumption per home residents. Keywords : water, solar power, hydram pump, water hammer,Banteran,green infrastucture.

Abstract

Rice-field rat (Rattus argentiventer) is a rodent that has a high level of productivity. These animals attack rice plants from the vegetative to the generative phase. This research aimed to analyze and to predict the accuracy of the use of owls with mathematical equations model in Kebokura and Lebeng villages, Sumpiuh district. Lotka - Volterra and Competitive Lotka-Volterra models were used to predict the population dynamics of Owl (predator) and rice-field rats (prey), then Runge - Kutta numerical method was applied to analyze the population dynamics of predator and prey at a certain time. The results of the analyses using the Lotka – Volterra, Competitive Lotka - Volterra equations and simulation data, each graph data showed that the rats’ population was able to be maximally suppressed. Based on the analysis result, started with 24 owls and 1,689 rats, the rats’ population could be suppressed to 104 using Lotka – Volterra, and to 176 using the Competitive Lotka – Volterra model. Then in the first and second simulation, started with 50 and 100 owls and 1,689 rats, analysis using Lotka – Volterra and Competitive Lotka – Volterra showed that the rat population could be suppressed to as much as 126, 188 and 145, 189, respectively. Based on the analysis, it could be concluded that use of Serak Jawa owl strategy was able to reduce and stabilize the rat populations. Furthermore, the higher population of owls can prevent the population explosion of rats and can suppress the rat population to a lower number.

Abstract

Burung pipit menjadi salah satu ancaman bagi tanaman padi di sawah bagi petani yang menggunakan sistem irigasi di Desa Wandasari, Kecamatan Bojonggambir, Tasikmalaya. Hasil penelitian menunjukkan bahwa serangan hama, termasuk burung pipit, dapat mengakibatkan penurunan produktivitas padi sebesar 50% hingga 80%. Petani telah mencoba berbagai cara untuk mengusir burung pipit, mulai dari berteriak-teriak, memasang sangkar perangkap, hingga metode seperti memasang kaleng dengan tali atau bahkan berburu burung pipit dengan senjata api. Namun, karena keterbatasan pengawasan sawah, seringkali petani tidak berhasil menghalau burung pipit, dan akibatnya tanaman padi mereka terancam. Salah satu solusi yang telah diimplementasikan adalah penggunaan teknologi gelombang ultrasonik untuk mengusir burung pipit tanpa membunuhnya. Teknologi ini terdiri dari perangkat elektronik yang menggunakan sensor PIR untuk mendeteksi kehadiran burung pipit. Mikrokontroler Arduino digunakan sebagai otak utama yang terhubung ke relay. Amplifier berfungsi untuk menghasilkan gelombang ultrasonik, dan lampu LDR digunakan sebagai indikator pergerakan burung. Perangkat ini ditenagai oleh panel surya dan baterai 12 volt yang dapat diisi ulang saat kondisi malam atau intensitas sinar matahari rendah. Perangkat ini dapat berputar mengikuti pergerakan burung pipit dan mengeluarkan gelombang ultrasonik pada frekuensi 25 - 34,5 KHz selama 30 menit, tergantung pada gerakan burung. Perangkat ini memiliki jangkauan deteksi maksimal hingga 15 meter. Penggunaan perangkat pengusir burung pipit ini berhasil mengurangi dampak burung pipit pada tanaman padi di sawah sebesar 95% dan meningkatkan hasil panen petani. Inisiatif penerapan teknologi ini diharapkan dapat diperluas dan dikembangkan di wilayah lain untuk manfaat yang lebih luas.

Abstract

High ambient temperatures inside tropical greenhouses can significantly raise nutrient solution temperatures in vertical hydroponic systems, disrupting nutrient uptake and reducing plant productivity. This study focuses on the design and development of a nutrient cooling system (chiller) using two TEC1-12706 thermoelectric modules (Peltier) arranged in series to enhance heat dissipation performance. The nutrient solution is pumped from the reservoir to the cooling chamber using a 12 V DC pump and recirculated in a closed-loop configuration. The chiller system is fully automated, controlled by two DH48S digital timers operating simultaneously: one activates Peltier 1, while the other controls Peltier 2 via the NC output (5 minutes) and the pump via the NO output (30 seconds), enabling alternating programmed cooling and circulation. The entire chiller unit is active only from 08:00 to 18:00 WITA using a KG316T programmable timer, corresponding to peak thermal stress hours inside the greenhouse. Results showed that despite greenhouse temperatures reaching up to 39.4 °C with relative humidity dropping to 47.6%, the chiller system maintained nutrient solution temperatures within the optimal 27–30 °C range. This design proved effective in reducing and stabilizing nutrient temperature under high heat microclimates. With its simple, automated, and energy-efficient architecture, the chiller system offers a promising solution for small-scale vertical hydroponics and greenhouse-based urban farming in tropical regions.
