Abstract

Mobile Poultry Slaughterhouse Halal (MPSH) is a mobile facility designed to carry out the process of slaughtering chickens in accordance with halal principles in the Islamic religion. Making a prototype of this tool aims to test the functionality of a system or product. The machine development designed in this research uses a drive (transmission) as a combination of pulley and v-belt. The reason for using a drive system as a pulley and v-belt is that it feels easier and more efficient in the work process. This research aims to analyze the calculation of pulley and v-belt sizes suitable for the plucker machine that was developed. This research uses an experimental design method, namely carrying out measurements, observations, and calculations of the technical specifications of the machine, then analyzing the data to obtain an idea of the machine's performance, which ultimately can provide an idea of the suitability of the machine. The research results obtained: (1) pulley sizes 100 mm and 175 mm in diameter, made from ST37 steel. (2) Required v-belt length = 1,253.95 mm. (3) V-belt axis distance = 426.25 mm. (4) The circumferential speed of the driving pulley vP = 10.99 m/s. (5) The circumferential force that arises Frate = 111.37 N. (6) The number of belts used is 1 belt.

Abstract

The rapid growth of bioinformatics has significantly influenced both the biological sciences and education, underscoring the importance of equipping future biology educators with relevant analytical and computational skills. This study aimed to compare the bioinformatics skills and biological knowledge of biology education students with and without experience in bioinformatics courses. A comparative descriptive design was employed, involving 49 students: 26 with no prior experience in bioinformatics and 23 with experience in bioinformatics. Data were collected using an instrument consisting of three opinion-based items and three cognitive test items. Qualitative data were analyzed thematically and visualized through diagrams, while cognitive performance was analyzed using descriptive statistics. The outcomes show that students who took the bioinformatics course demonstrated a broader use of tools, more reflective thinking about their own learning, and encountered more difficult problems, along with greater gain in scores on biology knowledge (70.29%) compared to students who did not take the course (63.63%). These findings support the need to include bioinformatics in the biology education program to better prepare pre-service biology teachers with the science and technology advancements in the future
