Abstract

ABSTRACT The purpose of this study was to determine and analyze the financial and non-financial viability of Mr. M. Sanif's tempe home industry during the COVID-19 pandemic. This was a descriptive study that employed a qualitative approach. Observation, interviewing, and documentation were used for data collection. The results show that the financial aspect has a total production cost of Rp. 235.873.000 with a net profit of Rp. 167.327.000. On a non�financial level, it operates without a business license; marketing is conducted in the SMEP market through direct sales to consumers; environmental concerns regarding liquid waste management are addressed through the construction of water channels; and solid waste is used as animal feed. On a technical level, the production location is close to the location of theraw materials and sales, themanagement and human resources management divisions have two employees, and regarding social and economic aspects,this industry gives benefit by employingpeople of the surrounding community. The BEP price of rectangular tempe is Rp. 964 with a BEP quantity of 231 pieces, the BEP price of long tempe is Rp. 963 with a BEP quantity of 212 pieces, the R/C Ratio is 1.71, the B/C Ratio is 0.71, the ROI is 65%, the NPV is Rp 534.261.783 and the PI is 3,07%.

Abstract

Shallot peel waste contains acetogenin, saponin, and squamocin compounds which can be used as botanical pesticides. The purpose of this research was to determine the effect of shallot peel pesticides on the mortality of Aphis gossypii. The research method used was Completely Randomized Design (CRD). The research data were analyzed using Analysis of Variances (ANOVA) and then continued with the Duncan’s test. The testing phase for pests by preparing 5 concentrations of the extract 0 ppm, 125 ppm, 250 ppm, 500 ppm, and 1,000 ppm. Based on the observations, it was obtained that data at a concentration of 0 ppm did not affect mortality, at a concentration of 125 ppm it had an effect of 47%, at a concentration of 250 ppm it had an effect of 67%, at a concentration of 500 ppm it had an effect of 93%, and at a concentration of 1,000 ppm it had an effect of 100%. Thus, 1,000 ppm is the concentration that has the most influence on the mortality of A. gossypii.  Keywords:  shallot peel extract,  botanical pesticides, A. gossypii

Abstract

To reduce pollution caused by fuel spills during the refueling process, this research designs and implements an automatic fuel filling device on a wooden boat with a capacity of 6 GT. This system consists of the JSN-SR04T ultrasonic sensor unit, an automatic pump, Neopixel-based LED visual indicators, and a microcontroller as the control center. This tool is designed to automate the fuel transfer process from the dock tank to the ship's tank without the need for manual intervention, thereby increasing operational efficiency and safety. Laboratory tests show that the system has high accuracy, with a Root Mean Square Error (RMSE) value of 0.30 cm, equivalent to an accuracy level of 99.39% in measuring the fuel surface height. In field tests on the Sungai Ungar–Batam route, this device was able to fill 75.76 liters of fuel in 9 minutes and 29.15 liters in 3 minutes automatically. The system is capable of detecting fuel levels, activating the pump when needed, and providing real-time visual notifications. The system's performance is affected by turbulence in the tank when the ship is moving, which reduces the stability of the sensor readings. Therefore, the use of sensors that are more resistant to dynamic conditions and the expansion of testing on larger capacity ships will be the next direction for development.

Abstract

This study aims to evaluate the effect of High-Intensity Interval Training (HIIT) on improving physical endurance performance and reducing the risk of injury in football players. This study utilizes a quasi-experimental design with a one-group pre-test and post-test approach involving 20 football players aged 18 to 25. Resistance performance is measured through VO₂ Max, while injury risk is assessed using body functional tests that evaluate muscle imbalances and biomechanical weakness. After undergoing the HIIT program for 8 weeks, the results showed a significant improvement in the players' VO₂ Max from an average of 61.87 ± 6.03 ml/kg/min to 63.60 ± 6.03 ml/kg/min, with an increase of 2.8% (p < 0.05). In addition, the risk of injury also decreased from an average of 4.11 ± 0.86 to 4.07 ± 0.86, with a decrease of 1.1% which was also statistically significant (p < 0.05). The increase in VO₂ Max reflects the increase in the player's cardiovascular endurance, which is crucial for dealing with the physical demands of a football match. The research also reveals that the reduced risk of injury suggests that HIIT effectively improves muscle stability, flexibility, and balance, which are important in preventing muscle and joint injuries in football players. In conclusion, HIIT is an efficient and effective training method to improve physical performance and reduce the risk of injury, so it is recommended to be applied in the training program of football players
