Abstract

The microclimatic environment during the brooding phase (Days 1–14 post-hatch) is the single most decisive factor governing the survival, growth kinetics, and physiological health of Kampung Unggul Balitbangtan (KUB) Day-Old Chicks (DOC). Due to immature thermoregulatory centers and the absence of thermal insulation, DOCs are poikilothermic and highly susceptible to ambient temperature drops and humidity swings. Conventional bang-bang (ON-OFF) and manual control systems suffer from severe thermal oscillations, actuator chatter, high energy waste, and inrush current surges. This research designs, implements, and rigorously analyzes an intelligent closed-loop microclimate regulation system driven by an embedded Mamdani Fuzzy Logic Controller (FLC) executed on an ESP32 dual-core 32-bit microcontroller. The sensory architecture integrates a high-precision Aosong DHT20 sensor over a deterministic hardware I2C bus for concurrent temperature and relative humidity (RH) acquisition, coupled with a 5:1 metal-film resistive voltage divider monitoring the primary 12V DC power supply rail. The FLC processes error e(T), error rate Δe(T), and RH to modulate ceramic infrared heaters via solid-state zero-crossing phase dimming and variable-speed 12V DC exhaust ventilation. Static metrological calibration against Fluke 971 and Keysight 34461A standards established a Mean Absolute Error (MAE) of 0.182 °C (R² = 0.9998) for temperature, 0.740% for RH (R² = 0.9993), and 0.021 V for power supply rail voltage (R² = 0.9999). Dynamic 24-hour testing under tropical ambient disturbances (22.5–33.8 °C; 56.4–94.6% RH) proved that the proposed FLC maintained brooder temperature with extreme precision at 33.51 ± 0.14 °C (Thermal Stability Index TSI = 99.8%) and RH at 65.2 ± 1.4%, effectively eliminating the ±0.75 °C overshoot/undershoot cycles typical of hysteresis controllers. Biological validation across a 14-day live trial with n = 300 KUB DOC chicks demonstrated that the Fuzzy IoT system suppressed cumulative mortality to 0.67% (vs. 8.00% conventional and 3.00% ON-OFF), increased final Day-14 mean body weight to 374.2 ± 11.6 g (+51.4% over conventional), achieved an extraordinary Feed Conversion Ratio (FCR) of 1.18 (vs. 1.62 conventional), and reduced electrical consumption by 48.6%. The study confirms that fuzzy logic environmental modulation provides superior microclimate stability, animal welfare, and energetic efficiency for smart precision poultry farming.

Abstract

The temporary closure of the final disposal site (landfill) for 1–2 days during holidays causes waste accumulation, which has become a concern among residents. BUMDes Moroberkah's waste management still relies on manual open burning, resulting in air pollution and scattered combustion residues. This community service program aimed to provide a solution by implementing appropriate technology in the form of an incinerator machine. The program was conducted in two stages: on-site machine testing, followed by unit handover and training for BUMDes management. Test results showed that the incinerator operated optimally, with a waste-reduction capacity of about 25 kg/hour. The internal air circulation system and chimney design effectively reduced exhaust emissions, while the machine contained combustion residues, helping maintain environmental cleanliness. The program also improved the BUMDes management’s understanding of standard operating procedures (SOPs) for machine operation and maintenance. This program provides an independent, comprehensive, and environmentally friendly waste management solution.

Abstract

Listrik merupakan sumber energi yang sangat penting untuk menunjang semua aktivitas manusia, dan pembangkit listrik tenaga surya (PLTS) telah menjadi perbincangan yang menarik belakangan ini. Jenis PLTS yang memanfaatkan limbah menjadi tema yang menarik, namun banyak pihak yang tidak bisa memaksimalkan potensi tersebut akibat berbagai keterbatasan, khususnya dalam hal transfer knowledge pada instalasi PLTS untuk mendukung UMKM. Dalam kegiatan Pengabdian kepada Masyarakat, perlu dilakukan transfer knowledge pada instalasi PLTS, yang diadakan di daerah Krajan Barat RT 05, RW 03, Kelurahan Bergaslor, Kecamatan Bergas, Kabupaten Semarang. Kegiatan ini dilakukan dengan langkah-langkah berupa penyuluhan, pelatihan, dan praktik langsung guna menjawab permasalahan yang dihadapi oleh mitra. Hasilnya menunjukkan bahwa transfer knowledge tentang panel surya yang menggunakan limbah rumah tangga terbukti membantu mitra dalam menambah pengetahuan dan keterampilan mereka serta mendapatkan rancangan panel surya berbasis limbah rumah tangga dengan daya maksimal 120 Watt yang di implementasikan kepada 5 orang Mitra UMKM di wilayah RT 05 RW 03 Kelurahan Bergaslor. Kegiatan Pengabdian Kepada Masyarakat ini dapat mendukung kemandirian energi bagi mitra dan masyarakat sekitar sehingga kegiatan UMKM dapat berjalan dengan baik. Temuan ini menegaskan bahwa transfer knowledge panel surya berbasis limbah rumah tangga memberikan kontribusi yang signifikan dan memiliki potensi untuk diterapkan lebih luas di lapangan.
