Abstract

Egg incubators are devices designed to create optimal conditions for eggs to hatch into chicks. Several important factors that must be considered in the egg incubator include temperature, humidity and air flow rate in the egg incubator chamber. Simulation of heat propagation and airflow rate in the hatchery was carried out using CFD software. The simulation results of heat propagation with a heating source above the egg rack obtained a maximum temperature of 312oK or the equivalent of 38.85o C which is right below the heater while the lowest temperature is 311°K or the equivalent of 37.85°C which is in the corner of the hatchery. The simulation results of the air flow rate with an air flow velocity of 1m/s obtained that the egg incubator with a heating source above the egg rack has an air flow rate in the hatchery space that is evenly distributed throughout the room so that the air can reach all the eggs in the hatchery room with a level hatching success of 80.5%.

Abstract

Drying is the process of removing water or separating a relatively small amount of water from a material using heat energy. One method of drying is through oven processing, which aims to reduce the moisture content in materials using an oven. This study aims to analyze the airflow rate in an oven using Computational Fluid Dynamics (CFD) simulation and to examine the effect of temperature variations on airflow rate using CFD simulation. The research method employed is experimental, with data collection techniques including descriptive analysis, involving experiments, simulation results, and documentation. The study found that the simulated airflow rate using Ansys R2 2020 varied with different temperatures. At 70℃, the air velocity ranged from 1.108 m/s to 4.432 m/s, while at 75℃, it ranged from 1.882 m/s to 11.29 m/s. Turbulence occurred at both temperatures, and higher temperatures resulted in faster airflow rates due to reduced air resistance. At 75℃, the crackers achieved optimal dryness, with a weight reduction of 95%. High temperatures can reduce air density which can increase air flow speed due to a decrease in resistance experienced by the air.

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

Perkembangan teknologi pengenalan gerakan manusia telah mendorong inovasi dalam pengendalian robot humanoid berbasis visi komputer. Penelitian ini bertujuan untuk mengimplementasikan sistem kendali lengan robot humanoid menggunakan framework MediaPipe berbasis Python yang diintegrasikan dengan kamera laptop sebagai sensor utama. Sistem ini dirancang untuk meniru gerakan tangan manusia secara real-time, dengan memanfaatkan data landmark pose tubuh yang dihasilkan oleh MediaPipe Pose Tracking. Koordinat titik-titik tubuh (bahu, siku, pergelangan tangan) dikalkulasikan menjadi sudut artikulasi menggunakan prinsip trigonometri vektor, kemudian dikonversi ke dalam sinyal kendali motor servo. Rangka robot dibangun menggunakan komponen cetak 3D berbahan PLA dengan konfigurasi sambungan pada bahu, siku, dan pergelangan tangan. Servo HS-805BB digunakan sebagai aktuator utama yang dikendalikan oleh mikrokontroler ESP32 melalui komunikasi serial. Hasil pengujian menunjukkan bahwa sistem mampu meniru gerakan tangan dengan tingkat responsivitas yang baik dalam lingkungan terkendali. Rentang gerak robot mendekati proporsi gerakan manusia, dengan gerakan fleksi siku mencapai 135° atau 93% dari gerakan alami. Beban torsi pada sambungan bahu sebesar 20 kg·cm masih berada dalam batas aman dari kapasitas servo. Kesimpulannya, sistem ini berhasil merepresentasikan prototipe awal kendali robot humanoid berbasis visi yang efektif dan ekonomis. Pengembangan lebih lanjut disarankan pada aspek stabilitas gerakan, akurasi pelacakan, dan adaptasi terhadap kondisi pencahayaan yang dinamis. Kata kunci: MediaPipe, robot humanoid, kendali visual, servo, Python, ESP32

Abstract

Technological advancements, including 3D printing, enable the creation of prototypes from digital designs using 3D printers. A popular method is Fused Deposition Modeling (FDM) with thermoplastic materials such as Acrylonitrile Butadiene Styrene (ABS), valued for its quality and affordability. In 3D printing, nozzle temperature and infill type influence the mechanical properties of printed objects. This study aims to determine the tensile strength of ABS with variations in nozzle temperature and infill type. Tensile test results show that a 230°C nozzle temperature produces higher yield strength for most infill types compared to 240°C. The 240°C setting tends to increase maximum tensile strength for grid and concentric infills, but not for gyroid and lines. The concentric infill type exhibited the highest elongation at both temperatures, indicating greater ductility compared to other infill types. These findings are expected to serve as a reference for optimizing printing parameters.

Abstract

This study analyzes the effect of tire tread depth and tire pressure on braking force in a Mitsubishi L300 vehicle. An experimental method was applied with variations in tread depth (>1 mm and <1 mm) and tire pressure (30 psi, 50 psi, and 60 psi). Results indicate that both variables significantly affect braking efficiency. The 50 psi–50 psi combination at >1 mm tread depth yielded the highest efficiency (86%), whereas the 30 psi–30 psi combination at <1 mm tread depth recorded the lowest (48%). A tread depth of <1 mm reduced braking efficiency by 15–20% on average. Tire pressures below or above the standard decreased braking performance by 10–15%. Maintaining balanced tire pressure at 50 psi and a minimum tread depth of 1 mm is recommended for driving safety.
