Abstract

The main problems in drying crackers are non-uniform drying and drying that still uses solar energy. During the rainy season, the process of drying crackers cannot be done quickly or takes a long time, thereby reducing the amount of cracker production in cracker MSMEs. Therefore, the solution that can be used is to use simple technology, a cracker drying oven machine, which can help the productivity of cracker small businesses in the drying process when the rainy season arrives. This research aims to determine the heat distribution in the cracker drying oven box using Computational Fluid Dynamics, determine the optimal temperature for drying crackers using a cracker drying oven machine and find out how long it takes to dry crackers using a cracker drying oven machine. From the simulation results using Ansys Fluent 19.2 software, it was found that the heat distribution was almost even in the drying box on each shelf with a heating source inlet of 75 ˚C with a temperature range of 49 ˚C - 54 ˚C on each shelf in stages. From the direct experimental results, it was found that the drying process with a heating source of 75 ˚C resulted in a decrease in the weight of crackers from the initial unit weight of 6 grams and the final unit weight of crackers of 3 grams. The drying process with a cracker drying oven machine lasts for 3 hours to achieve complete drying. Keywords: Cracker drying oven machine, heat distribution, computational fluid dynamics

Abstract

The main problem in drying crackers is that drying is not uniform and still uses solar heat. In the rainy season, the process of drying crackers cannot be done quickly or takes longer, thereby reducing the amount of cracker production in cracker MSMEs. The solution to the problem in the drying process is to use technology in the form of a cracker drying oven. The cracker drying oven was made at the UMKM Kerupuk Fantasi location so you could try it straight away. From the experimental results it is known that the drying process at a temperature of 75˚C results in a greater reduction in cracker weight than the drying process at a temperature of 70˚C. The drying process in a cracker drying oven is carried out for 3 hours to get perfectly dry crackers. Drying time using a cracker drying oven is faster than drying time using solar heat. By reducing drying time, cracker production capacity will increase.

Abstract

AbstractEgg incubator on the market consists of three systems, namely manual, semi-automatic and automatic. The three egg hatching systems use water as a medium to control temperature and humidity in the hatchery. The use of water in the hatchery is very troublesome because it must always monitor the availability of water due to evaporation. In addition, the presence of water in the hatchery can invite mosquitoes to nest. For this reason, the author uses air as a medium to control temperature and humidity in the hatchery so that these things do not happen. In this study, analysis and simulation was carried out using Matlab software to find the best rise time value for the distance between the heating element and the egg rack so that the temperature on the egg rack was 38oC. In addition, an analysis of heat propagation from the heat source (heating element) to the egg rack was carried out using Solidworks software. Furthermore, an analysis of the air flow rate in the hatchery was carried out in the ventilation holes below and above the hatchery using solidworks software. After all the simulation data is obtained, a prototype is made to test the hatch percentage value on the egg incubator made. From the simulation results of the Matlab software, the distance between the heater and the egg rack is 11 cm, which has the best rise time value of 2.8 minutes. The simulation results from the Matlab software then simulated heat propagation using the Solidworks software on the egg rack to obtain a temperature of around 50oC. The simulation results of several air ventilation holes in the hatchery against the air flow rate obtained an even air flow rate in the hatchery. From the observation of the egg incubator prototype, the temperature was 38oC and the humidity was between 56% - 72% and the average hatching percentage was 28%.

Abstract

Air tanah merupakan sumber utama air bersih yang dimanfaatkan masyarakat untuk kebutuhan harian seperti mandi, mencuci, memasak, dan konsumsi. Namun, kualitas air sumur sering kali menurun akibat kontaminasi lingkungan seperti intrusi air laut, rembesan limbah domestik seperti rembesan septic tank, serta tingginya kandungan logam berat dan partikel tersuspensi. Masalah ini umum terjadi di daerah pesisir dan kawasan pemukiman padat dengan sanitasi yang kurang memadai. Penelitian ini bertujuan untuk merancang dan menguji prototype alat ukur kualitas air sumur dengan pendekatan fuzzy logic mamdani, yang mengklasifikasikan kualitas air ke dalam tiga kategori yaitu baik, cukup, dan buruk. Sistem dirancang menggunakan mikrokontroler ESP32 yang terintegrasi dengan sensor salinitas, pH, dan kekeruhan. Data ditampilkan secara real-time pada layar LCD. Pengujian dilakukan terhadap sampel air sumur di wilayah Kaligawe, Kota Semarang. Sensor salinitas menunjukkan akurasi 94,76% dengan kadar garam 1438 ppm, melebihi ambang batas air layak konsumsi. Sensor pH memiliki akurasi 92,90% dengan nilai pH 7,9, masih dalam rentang standar (6,5–8,5). Sensor kekeruhan mencatat akurasi 90,89% dengan nilai 10,6 NTU, di atas batas aman 5 NTU. Validasi dengan MATLAB menunjukkan deviasi rata-rata hanya 0,88%, menandakan sistem memiliki tingkat presisi yang sangat baik. Hasil menunjukkan bahwa air sumur tidak layak dikonsumsi karena tingginya kadar garam, sesuai dengan batasan dalam Permenkes No. 2 Tahun 2023.

Abstract

Public bus drivers are at risk of health issues due to mechanical vibrations and non-ergonomic working postures during long working hours. This study analyzed vibration levels and ergonomic risks of Trans Jateng Corridor 4 bus drivers using an experimental method with an MPU6050 accelerometer sensor at three points: brake/clutch pedal, steering wheel, and driver’s seat at various operational speeds. Ergonomic assessment was conducted using the Rapid Upper Limb Assessment (RULA) method with CATIA V5R20 software during two main work phases. Results showed the highest vibration level on the brake/clutch pedal (3.23 m/s²), still below the threshold limit of 5 m/s² for 6–8 hours of work as regulated by the Ministry of Manpower Decree No. 5/2018. The lowest vibrations were recorded on the steering wheel (0.79 m/s²) and driver’s seat (0.93 m/s²). A RULA score of 3 in both phases indicated a “low risk” category but required long-term preventive measures. Recommendations include the use of anti-vibration footwear, structured breaks every 90 minutes, and driver rotation with a maximum of 6 hours per shift to maintain optimal working conditions and prevent occupational health disorders.

Abstract

This study evaluates the effectiveness of Automated Rubber Tyred Gantry (ARTG) as an alternative to manual RTG operations at the Semarang Container Terminal. The research focuses on productivity (boxes/hour), maintenance cost efficiency (IDR/month), and workplace safety (number of incidents). A descriptive quantitative case study was conducted from March to May 2025. Results show that ARTG improved productivity by 11.25%, reduced maintenance costs by 46.5%, and recorded zero incidents compared to four incidents with manual RTG. All differences were statistically significant (p < 0.05). These findings indicate that ARTG enhances operational efficiency and safety in port operations. Gradual implementation of ARTG is recommended, considering digital infrastructure readiness, human resource training, and policy support.

Abstract

This study aims to design and evaluate the performance of a prototype air quality monitoring device integrated with an exhaust fan in a vehicle testing room. The experimental method was employed to examine the relationship between variables. The increasing number of motor vehicles has an impact on air quality, particularly in emission testing areas. The device utilizes an MQ-7 sensor for gas detection and a DHT22 sensor for temperature and humidity, with data displayed in real time on an LCD screen. When the gas concentration exceeds nine ppm, the system activates an audible alarm and automatically turns on the exhaust fan to maintain air circulation. The exhaust fan expels hot air from the room while bringing in cooler outside air. Test results indicate that the device operates stably and provides accurate data, making it suitable as an air quality monitoring system in motor vehicle testing facilities.
