Abstract

Musim kemarau dapat menyebabkan perubahan suhu dan kelembapan tanah pada tanaman aglaonema menjadi kurang optimal. Hal tersebut dapat mempengaruhi keindahan warna dan corak daunnya. Penelitian ini bertujuan untuk merancang sistem monitoring tanaman aglaonema secara online. Sistem yang dikembangkan adalah sistem telemonitoring berbasis mikrokontroler ESP32 yang dilengkapi dengan kemampuan untuk terhubung perangkat lain melalui internet. Monitoring suhu dilakukan dengan memanfaatkan sensor DS18B20, monitoring kelembapan tanah dengan sensor YL-69, dan monitoring pH tanah dilakukan dengan memanfaatkan sensor pH tanah. Hasil pengukuran besaran fisik oleh ketiga sensor ini diolah oleh mikrokontroler dan selanjutnya data monitoring ini akan dikirimkan ke pengguna melalui jaringan internet. Selanjutnya pengguna menerima data hasil monitoring ini melalui aplikasi blynk yang ada pada telepon genggam. Selain pengiriman data melalui internet, alat ini juga bisa menampilkan data monitoring di tempat dengan penampil LCD. Pengujian kinerja alat memperlihatkan bahwa alat. dapat bekerja dengan baik sesuai rancangan. Hasil uji coba yang dilakukan sebanyak 10 kali percobaan pada media tanaman mempelihatkan hasil rata-rata persentase kesalahan alat masing-masing sebesar 3,032% untuk sensor suhu, 9,08% untuk sensor kelembapan tanah, dan 6,34% untuk sensor pH tanah.

Abstract

Implementation of automation greatly facilitates the work of a system. This research automates the search for perspective transformation coordinates. In previous study, the process was done manually and was considered time-consuming and costly. The search for these coordinates is carried out with the help of red circles at several points in the parking area to be identified. There are two cases of images to be automated, namely the image of the parking area without obstacles and with obstacles. In the unobstructed images, the identification of transformation coordinates is carried out by identifying the coordinates of the auxiliary circle. Whereas in the images with obstructions, the identification of the transformation coordinates also involves the intersection equations of lines. The process of identifying the coordinates is done with the condition of the parking lot without a single vehicle. Once the coordinates are obtained, all coordinates are stored and will be used in the perspective transformation process in status parking slot identification stage. The identification stage is same with previous study. The proposed system 100% able to identify the transformation coordinates and carry out the perspective transformation process as expected. Of the 900 samples in each case, we acquire 100% recall, and most of the parking slot identification status being above 85% precision and accuracy. Compared to previous studies, the proposed system is more effective, with recall, precision, and accuracy values at 100%. The effectiveness of the proposed system is even more evident with average data automation time is 31.689 seconds.

Abstract

Kelompok Gandos Berkah di Colomadu menghadapi tantangan serius berupa defisit pakan hijauan selama musim kemarau yang mengakibatkan tingginya biaya operasional dan potensi penurunan produktivitas ternak. Kegiatan pengabdian masyarakat (PkM) ini bertujuan untuk mengoptimalkan kemandirian Bank Pakan kelompok melalui integrasi teknologi pakan awetan. Metode pelaksanaan selama enam bulan menggunakan pendekatan Participatory Action Research. Intervensi utama adalah (1) pembangunan infrastruktur Bank Pakan Hijau seluas 2.400 m² yang dilengkapi sistem irigasi teknis mandiri (Sumur Sibel/pompa air sumur dalam dan tandon air), dan (2) transfer teknologi pembuatan Silase sebagai pakan cadangan serta pengolahan limbah menjadi Pupuk Kompos (sistem zero-waste). Hasil utama kegiatan adalah terwujudnya infrastruktur Bank Pakan yang fungsional dan peningkatan penguasaan teknis anggota kelompok dalam manajemen pakan awetan. Adopsi sistem ini telah menciptakan fondasi kemandirian yang diproyeksikan mampu mencapai efisiensi biaya pembelian pakan luar hingga 30%. Dengan demikian, optimalisasi Bank Pakan berbasis Silase terbukti efektif memitigasi risiko pakan musiman, mendukung efisiensi, dan menciptakan usaha peternakan yang berkelanjutan bagi Kelompok Gandos Berkah.

Abstract

The implementation of micro-hydro power plants (MHPPs) offers a strategic solution for achieving energy independence, particularly within remote communities. This study proposes the development of a hydroelectric power generator with a vertical axis turbine, designed not only as a source of clean energy but also to minimize visual pollution. The system maximizes submerged components, thereby reducing its visual impact. Although MHPPs technology is widely applied to address electrification challenges in remote areas, the system proposed in this study, with its components predominantly submerged below the water surface, offers a visually unobtrusive solution that is also well-suited for urban environments. However, conventional locked-blade turbines often experience significant efficiency losses due to counter-flow pressure acting on blades moving against the water stream, highlighting the need for an adaptive mechanism to minimize drag and optimize energy capture. The hydroelectric power generator using vertical axis turbine with adaptive blades consistently demonstrated better performance than a system using locked blades. The adaptive-blade configuration outperformed the locked-blade system, exhibiting a 5.1% increase in average turbine efficiency and a 3.5% improvement in overall system efficiency.
