Abstract

The red fruit (Pandanus conoideus) is an endemic plant from Papua, known for its distinctive color and shape. This fruit is recognized for its bioactive properties, such as antioxidant, anti-inflammatory, and antihyperglycemic effects. Its high pigment content is believed to have potential as a sensitizer in DSSC applications. However, research on this topic remains underexplored. Therefore, the aim of this preliminary study is to investigate the potential of red fruit pigments for DSSC. The characterization of red fruit pigments was conducted through phytochemical screening, FTIR and UV-Vis spectral analysis, as well as literature reviews. Pigment extraction was carried out using maceration without involving drying or grinding processes. Phytochemical screening results revealed that the macerate contains flavonoids, alkaloids, phenolics and terpenoids, compounds commonly used as natural pigments in DSSCs. FTIR analysis showed the presence of functional groups such as carboxyl (-COOH), carbonyl (C=O), and hydroxyl (-OH), which can act as effective anchoring groups when interacting with nanosemiconductor surfaces. Meanwhile, UV-Vis analysis showed absorption peaks in the UV region (wavelength 204–399 nm) and the visible region (wavelength 400–550 nm). Based on literature studies and research findings, it can be concluded that the pigments in red fruit have potential applications as DSSC sensitizers.

Abstract

Background: Broiler chickens are highly sensitive to temperature changes due to their inability to sweat, making them vulnerable to heat stress and respiratory illnesses. Manual monitoring methods are inadequate in maintaining optimal environmental conditions, especially in regions with unstable power supply. This study addresses the need for an autonomous system to regulate temperature and lighting in poultry housing. Methods: An IoT-based solution was developed using Arduino Uno and NodeMCU ESP8266 microcontrollers, coupled with a DHT11 temperature and humidity sensor. The system employed incandescent lamps for heating and axial fans for cooling, activated based on temperature thresholds. Real-time data were displayed on an LCD and transmitted to the Blynk mobile application for remote access. A 12V battery and inverter ensured continuous operation during power outages. Findings: The system maintained stable temperature conditions between 31°C and 34°C. When the temperature dropped below 31°C, the lamp activated; when it rose above 34°C, the fan turned on. Data were reliably recorded and displayed over a 24-hour period. All hardware components functioned effectively, and system performance was consistent even during transitions to backup power. Conclusion: This research confirms the effectiveness of a low-cost IoT-based system for automated environmental control in broiler poultry housing. The system provides a reliable, remote-controlled solution that improves animal welfare, minimizes manual labor, and ensures operational resilience in power-limited settings. Novelty: The proposed system combines real-time environmental monitoring, remote access, and automated actuation with a backup power feature in a compact and affordable design. It is specifically tailored for small-scale poultry operations in developing regions, filling a critical gap in accessible precision farming tools.

Abstract

Kebutuhan akan listrik telah menjadi salah satu hal penting bagi masyarakat saat ini. Lebih dari 88% dari sumber energi listrik berasal dari bahan bakar fosil. Pemanfaatan sumber energi yang tidak dapat diperbarui menyebabkan konsekuensi buruk bagi lingkungan. Untuk menanggulangi masalah tersebut serta mengurangi beban listrik PLN yang meningkat, penting untuk mengembangkan teknologi energi terbarukan yang bersifat ramah lingkungan. Memanfaatkan energi matahari melalui pembangunan pembangkit listrik tenaga surya (PLTS) adalah langkah yang sesuai untuk memenuhi kebutuhan pokok akan listrik. Balai Kampung Wamfoura memiliki luas atap yang cukup besar dan memiliki potensi iradiasi/intensitas sinar matahari sebesar 4,648 kWh/m2/day menurut data Global Solar Atlas. Kampung Wamfoura memiliki masalah yaitu hanya teraliri listrik PLN dari pukul 6 sore hingga pukul 6 pagi. Untuk mengatasi masalah tersebut dilakukan penelitian ini untuk merencanakan PLTS off-grid pada Gedung Balai Kampung Wamfoura. Untuk memenuhi konsumsi listrik harian Balai Kampung Wamfoura yaitu sebesar 9,952 kWh/hari dibutuhkan 14 panel surya dengan kapasitas 380 Wp, 24 buah baterai dengan kapasitas 296 Ah, dan 2 inverter dengan kapasitas 4000 W. Simulasi PVSyst menghasilkan 3632.5 kWh per tahun dengan performance ratio 35%. Dengan hasil produksi energi listrik tersebut maka dapat memenuhi konsumsi listrik harian Balai Kampung Wamfoura.

Abstract

Pengelolaan parkir secara konvensional masih memiliki keterbatasan dalam pemantauan kendaraan, pengendalian akses, dan pencatatan data secara terstruktur. Sistem dirancang untuk menangkap citra objek melalui ESP32-CAM, memproses deteksi motor menggunakan YOLOv3 pada Python, mengendalikan portal melalui motor servo, menyalakan lampu kilat pada kondisi tertentu, serta menyimpan data hasil deteksi ke basis data MySQL. Pengujian sistem dilakukan pada area parkir Lapangan Borasi, Manokwari, Papua Barat. Kontribusi penelitian ini terletak pada integrasi deteksi kendaraan roda dua berbasis YOLOv3 dengan sistem kontrol portal otomatis, pencahayaan adaptif menggunakan flash ESP32-CAM, serta penyimpanan data deteksi secara real-time ke basis data MySQL dalam satu sistem IoT yang terintegrasi. Pengujian dilakukan menggunakan 19 data uji yang terdiri atas 15 motor dan 4 objek bukan motor. Hasil pengujian menunjukkan bahwa 13 motor berhasil terdeteksi, sedangkan 2 motor tidak terdeteksi pada malam hari akibat rendahnya pencahayaan. Pada objek bukan motor, 2 mobil dan 1 orang berhasil dikenali sebagai bukan motor, sedangkan 1 sepeda salah terdeteksi sebagai motor. Berdasarkan confusion matrix, sistem memperoleh akurasi sebesar 84,21%, presisi motor sebesar 92,86%, dan recall sebesar 86,67%. Hasil ini menunjukkan bahwa sistem mampu melakukan deteksi motor dan pengendalian portal secara otomatis, meskipun masih dipengaruhi oleh kondisi pencahayaan dan kemiripan bentuk objek.
