Abstract

Gambir and green tea hold functional compounds contained in the category of polyphenolic compounds, one component of which is catechins. Catechins have antimicrobial properties because they have the ability to break down microbial cell chambers or precipitate proteins. The microbe Pseudomanas sp is often found in tilapia with a high level of pathogenicity. This research aims to examine the effect of Gambir Catechin and Green Tea concentrations to suppress the growth of Pseudomonas sp tilapia bacteria. The research method applied is tabulation and descriptive method. The concentration of catechin compounds was modified by 4%, 6%, 8%, and 10%. The results showed that the antimicrobial effect developed with an increase in the concentration of catechin compounds for catechin from gambier and green tea. This shows that there is a strong positive relationship between concentration and zone of inhibition and the catechin compounds of gambier and green tea have antimicrobial effects against Pseudomonas sp. The results of this research can be applied to develop tilapia aquaculture in the future.

Abstract

Three-phase induction motors are AC electric motors widely used in both industry and household applications. Over time, these motors experience a decline in performance, including a reduction in torque and efficiency due to the deterioration of material resistance. One of the challenges in measuring the efficiency of induction motors during operation is the difficulty in measuring the motor's output parameters without disconnecting the motor from its load. This study aims to provide an alternative solution for measuring the efficiency of three-phase induction motors while they are in operation in industrial settings. The method used involves calculating the load as a percentage of the motor's rated output capacity, followed by current load estimation using the Line Current Measurement method. A digital power meter, LCD module for data display, and PLC as a control device were employed for monitoring. The study was conducted on a 1.1 kW three-phase induction motor, tested in the Electrical Engineering Laboratory at POLNEP. The results show that the developed measurement device can monitor the motor's parameters and display efficiency in real-time. The accuracy of the device is good within the load range of 65% to 76% of the rated capacity, but decreases at lower load levels. Comparison between the measured values and theoretical calculations indicates a low margin of error at specific load ranges, with the error increasing as the load decreases. The optimal load range for the motor is between 60% and 80% of its rated capacity.

Abstract

This study examines cooperative practices in broiler chicken farming in Geragai District, where the prevalent core–plasma partnership model raises persistent issues of equity, transparency, and risk distribution. The primary objective is to describe the cooperation between plasma farmers and core companies and assess its alignment with Islamic economic principles. Employing a qualitative case study approach, data were collected through in-depth interviews, field observations, and document analysis, and were subjected to thematic analysis with triangulation to ensure validity. Findings indicate that core companies dominate price setting, chick quality, and harvest timing, while plasma farmers bear mortality risk and additional costs, producing an uneven allocation of profits and risks. Contracts are frequently insufficiently detailed or not fully documented in writing, resulting in ambiguous agreements that contravene Islamic commercial ethics. The study contributes theoretically by reaffirming the relevance of the concepts of syirkah and mudharabah in evaluating partnership models, and practically by recommending more equitable, transparent, and Sharia-compliant contracts. It also highlights implications for future research and the need to strengthen Sharia legal literacy among plasma farmers.

Abstract

The coastal waters of Indonesia are extensive, and one of the areas is the Mentawai Islands Regency. The Mentawai Islands are a distribution area for several types of turtles, including the leatherback turtle, green turtle, hawksbill turtle, and olive ridley turtle (Lepidochelys olivacea). The study focuses on the morphometric characteristics of olive ridley turtle hatchlings. Olive ridley turtles found in the Buggei Siata Turtle Conservation Area do not have complete morphometric data, so an observation of the morphometric characteristics of olive ridley hatchlings in this area was conducted. This study aims to determine the morphometric characteristics of olive ridley hatchlings and to complete the data for turtle conservation in Buggei Siata, Betumonga. The research was carried out from December 2021 to March 2022 at Buggei Siata Beach, Betumonga. The data analysis used ANOVA followed by Tukey's post-hoc test with 5 different nests and a total sample size of 35 hatchlings per nest. The results of the morphometric characteristics are as follows: carapace length (CL) ranged from 37.93 to 43.56 mm, carapace width (CW) from 28.36 to 36.35 mm, neck length (NL) from 10.08 to 14.21 mm, head width (HW) from 12.03 to 15.34 mm, front limb length (FLL) from 31.06 to 39.74 mm, plastron width (PW) from 19.74 to 29.85 mm, and weight from 13 to 18 grams. Significant differences were found between nests (p<0.05) in these measurements, while for head length (HL) from 16.98 to 19.91 mm, head height (HH) from 10.73 to 13.93 mm, rear limb length (RLL) from 11.37 to 21.88 mm, and plastron length (PL) from 23.86 to 37.21 mm, no significant differences were observed between nests (p>0.05). Based on the data, there are differences in the morphometric size of olive ridley hatchlings among the observed nests
