Abstract

Broiler chicken is a superior breed that has high productivity. Ammonia odor that pollutes the area around the cage is a problem in broiler management. Due to the activity of microorganisms in feces, unabsorbed protein amino acids, and other non-protein nitrogen (NPN) compounds break down into ammonia gas. In addition to damaging the environment, NH3 gas can interfere with animal performance, making them susceptible to disease. This research aims to solve the problem that comes from ammonia by measuring and designing an automatic ammonia gas controller based on Arduino using an MQ-135 sensor. If ammonia levels in the cage are greater than 5 ppm, ammonia levels are controlled by spraying liquid smoke to limit ammonia gas emissions. The results of this study show that the tool is able to reduce ammonia gas levels to 8 ppm. Ayam broiler adalah jenis ras unggulan yang memiliki daya produktivitas tinggi. Bau amoniak yang mencemari area sekitar kandang menjadi masalah dalam pengelolaan ayam broiler. Karena aktivitas mikroorganisme dalam feses, protein yang tidak diserap asam amino, dan senyawa nitrogen non-protein (NPN) lainnya terurai menjadi gas amoniak. Selain merusak lingkungan, gas NH3 dapat mengganggu performa hewan, sehingga rentan terkena penyakit. Penelitian ini bertujuan untuk mengatasi masalah yang berasal dari amonia dengan metode pengukuran dan perancangan alat pengontrol gas amoniak otomatis berbasis arduino menggunakan sensor MQ-135. Jika kadar amoniak di dalam kandang lebih besar dari 5 ppm, kadar amoniak dikendalikan dengan penyemprotan asap cair untuk membatasi emisi gas amoniak. Hasil dari penelitian ini alat tersebut mampu menurunkan kadar gas ammonia hingga 8 ppm.

Abstract

Solar energy can be converted into electricity through a thermoelectric generator that operates based on the Seebeck effect, where a greater temperature difference in the thermoelectric element produces a higher voltage. This research aims to evaluate the performance of a thermoelectric generator with various coolant fluids. The study utilized a prototype house with a corrugated zinc roof. Eight thermoelectric generators of SP 1848 27145 SA type, connected in series, were installed beneath the zinc roof. Data were collected over three days from 08:00 to 16:00 in an area exposed to direct sunlight. The results showed an average voltage of 0.593 V for air cooling, 0.539 V for water coolant, and 0.639 V for liquid cooling. From the data, the highest voltage achieved was 1.013 V with liquid cooling, indicating that liquid cooling provides superior cooling capability.

Abstract

PT. XYZ is a wheat flour producer. To produce quality flour requires risky labor. Work accidents from 2014 to 2022 were evaluated based on secondary data. This research detects work accidents in the Silo Department using the Hazard Identification And Risk Analysis (HIRA) and Fault Tree Analysis (FTA) methods. HIRA is used to detect risks and causes of work accidents. There are six activities in a silo that have the potential to cause work accidents, namely: stairs without handrails, sample display areas without steps, top steps that are loose and protrude upwards, open dump truck doors, placement of elevator chains, and opening ventilation at the top of the silo. Based on the results of the FTA analysis, it is known that the causes of work accidents are caused by ladders not being suitable for use, workers not using PPE, workers not understanding the work flow, workers being tired, workers not concentrating, workers being in a hurry. PT. XYZ adalah produsen tepung terigu. Untuk memproduksi tepung yang berkualitas memerlukan tenaga kerja yang berisiko. Kecelakaan kerja dari tahun 2014 hingga 2022 dievaluasi berdasarkan data sekunder. Penelitian ini mendeteksi kecelakaan kerja di Departemen Silo dengan menggunakan metode Hazard Identification And Risk Analysis (HIRA) dan Fault Tree Analysis (FTA). HIRA digunakan untuk mendeteksi risiko dan penyebab kecelakaan kerja. Terdapat enam aktivitas dalam silo yang berpotensi menimbulkan kecelakaan kerja, yaitu : tangga tanpa pegangan, area display sampel tanpa undakan, anak tangga paling atas yang kendur dan menonjol ke atas, pintu dump truck terbuka, penggantian rantai elevator, serta pembukaan ventilasi silo bagian atas. Berdasarkan hasil analisis FTA diketahui penyebab terjadinya kecelakaa kerja dikarenakan tangga tidak layak pakai, pekerja tidak menggunakan APD, pekerja tidak memahami alur kerja, pekerja dalam kondisi lelah pekerja tidak konsentrasi, pekerja tergesah-gesah.

Abstract

The development of energy storage materials requires facilities for testing the materials' ability to store and release energy effectively. This study focuses on the development and calibration of a temperature measurement system for parabolic solar collectors equipped with heat storage media. We employed type-K thermocouples and MAX6675 modules with Arduino as our measurement tools. The calibration process involved comparing sensor measurements with those obtained from commercially calibrated instruments using seven different test materials. The calibration results demonstrated that our sensors exhibited an error rate ranging from 0.66 to 0.73, indicating their accuracy and suitability for monitoring temperature fluctuations in solar thermal collectors.

Abstract

Indonesia, a tropical climate country, has experienced a notable increase in temperatures during the dry season due to global warming, leading to decreased thermal comfort. This experimental study aims to investigate and analyze the performance of an air-water heat exchanger serving as a passive cooler in tropical ventilation systems. Before being introduced into the room, the hot outdoor air is passively cooled by colder water. Air, propelled by an inline duct fan at a constant speed of 9.6 meters per second, passes through a PVC hose integrated into a tube filled with water measuring 100 cm in diameter and 110 cm in height, which serves as the main heat exchanger. Measurement results indicate that the designed air-water heat exchanger provides a significant passive cooling effect, reducing air temperature by up to 6.83°C. By harnessing passive cooling, the cooling capacity achieved during the measurement period in the ventilation system ranges from 3.08 kJ to 7.67 kJ. Indonesia, yang memiliki iklim tropis, mengalami kenaikan suhu yang cukup besar selama musim kemarau akibat pemanasan global, sehingga mengurangi kenyamanan termal. Penelitian eksperimental ini bertujuan untuk menguji dan menganalisis kinerja alat penukar panas udara-air yang berfungsi sebagai pendingin pasif dalam sistem ventilasi di daerah tropis. Sebelum masuk ke dalam ruangan, udara panas dari luar didinginkan secara pasif oleh air yang lebih dingin. Udara yang didorong oleh kipas saluran udara dengan kecepatan tetap sebesar 9,6 meter per detik melewati selang PVC yang terhubung dengan tabung berisi air berdiameter 100 cm dan tinggi 110 cm, yang berperan sebagai penukar panas utama. Hasil pengukuran menunjukkan bahwa penukar panas udara-air yang dirancang memberikan efek pendinginan pasif yang signifikan, mengurangi suhu udara hingga 6,83 °C. Dengan memanfaatkan pendinginan pasif, kapasitas pendinginan yang dicapai selama periode pengukuran dalam sistem ventilasi berkisar antara 3,08 kJ hingga 7,67 kJ.
