Abstract

Separation of CO2 gas from the biogas can be accomplished by adsorption process. An adsorbent has a maximum capacity, so the adsorbent will eventually be saturated at a certain time. Therefore, it is necessary to simulate the adsorption mass transfer to produce a breakthrough curve. The breakthrough curve from the simulation of adsorption mass transfer was validated with the experimental data. The research was conducted using variations in temperature and pressure. The mass transfer simulation was solved using the finite difference method. The adsorbent used in this research was 13X zeolite and the biogas was obtained from cow dung waste. Convergent curves can be obtained in numerical simulations as breakthrough curves. This research shows that adsorption should occur at low temperatures and high pressure. Column height and flow velocity also influence the breakthrough time. The comparison of the simulated breakthrough time with experimental data is not much different with R2 0.9969. The striking difference is in the adsorption zone with average relative error (ARE) values ranging from 9.57% to 20.49%. From the results of entropy, enthalpy, and Gibbs free energy calculations, the biogas adsorption research on the 13x zeolite column is an exothermic and spontaneous process

Abstract

GAKI (Gangguan Akibat Kekurangan Iodium) merupakan masalah kesehatan serius yang menyebabkan kualitas hidup dan perkembangan individu. Uji Eksperimental terhadap kualitas kadar garam berbasis variasi putaran dan waktu pengadukan penting untuk membantu mencegah GAKI, dengan mempertahankan nilai baume dari air tua pencuci garam pada nilai 25-28. Penelitian ini bertujuan untuk menguji kualitas kadar garam yang dihasilkan oleh mesin pengolahan garam dengan variasi putaran (40, 80, dan 120 rpm) dan waktu pengadukan (10, 15, dan 20 menit) dengan kadar awal yang digunakan dalam penelitian sebesar 85.67%. Hasil penelitian menunjukkan bahwa variasi putaran dan lama pengadukan sangat berpengaruh terhadap kualitas kadar garam. Pada penelitian ini dapat disimpulkan bahwa kecepatan putaran mesin 120 rpm dan lama pengadukan dibawah 10 Menit mendapatkan kenaikan kadar garam yang optimal sebesar 6.88% menjadi 91.55%.

Abstract

The salt washing unit is part of the salt processing machine. This unit's function is to wash raw salt with brine. This unit has a motor, agitator blade, washing chamber, and frame. The frame structure strength of the salt washing unit needs to be evaluated to ensure safety. This research aims to design the salt washing unit and obtain simulation results of frame structure strength to ensure the safety of the salt washing unit. This research was carried out by simulation to look for stress, strain, and changes in the shape of objects (displacement). The frame strength simulation was carried out using Solidwork software. The salt washing unit with a 50 kg/hour capacity has been designed. It has a cylindrical shape with 990 mm in height and 680 mm in diameter. From the simulation results of strain, it can be concluded that the minimum point is 1.80 × 108 Mpa, and the maximum point is 1.63 × 105 Mpa. From the simulation results of displacement, it can be concluded that the minimum point is 0 mm and the maximum point is 2,296 mm. The maximum stress is 5.254×106 N/m2, and the minimum stress point is 1.803×106 N/m2.

Abstract

One form of community service is the transfer of technology from universities to community groups. The Puspasari Women's Farmers Group (KWT) has a medicinal plant garden that produces medicinal plants, one of which is rhizomes. One of the shortcomings of drying the rhizomes is the drying process which is still conventional, this causes the quality of the rhizomes to be poor. The purpose of this service is, with the presence of an automatic dryer owned by the agricultural engineering study program of Ibn Khaldun University, it is hoped that there will be an increase in product quality and an increase in the understanding of KWT members regarding drying. After the implementation of the dryer training, training participants were given questionnaires and questions. As a result, the participants stated that the drying results with the automatic drying tool were much better than conventional drying. Participants were able to answer 60% of the questions given regarding basic drying knowledge.

Abstract

This research is an initial research in the development of cars with compressed air engine drivers. Modifications are made to the engine of 2-stroke motorized vehicles fueled by gasoline. Pressurized actuators using selenoid valves are ordered based on the piston position obtained from the proximity sensor. When the proximity sensor detects the piston is in the TMA position, the selenoid valve is ordered to open so that pressurized air enters the combustion chamber and pushes the piston to move to the TMB and turns back to TMA. The selenoid valve will close again when the proximity sensor detects that the piston is moving from TMA to TMB. Pressurized air is given to move the piston to produce a spin on the wheel. Air pressure is given at 0.92 bar to 2.36 bar resulting in a maximum rotating speed of 1035 rpm, torque of 1.33 Nm, and maximum power of 0.71 kW based on the results of static testing. This research will continue to be developed to optimize the torque and power produced so that cars driven by compressed air engines can be produced.
