Abstract

A Loadcell-Based Pencak Silat Kick Strength Measurement Tool This research aims to develop a kick strength measurement tool in the sport of pencak silat, addressing the subjective nature of measurements in the field. The primary technology used is a loadcell sensor to achieve accuracy and standardization. The development model applied is ADDIE (Analysis, Design, Development, Implementation, Evaluation), with a Research and Development (R&D) approach. This tool is equipped with a data recording feature and was tested on five pencak silat athletes from PSHT Bekasi. The test involved three types of kicks: T, crescent, and straight. Through data reading analysis and accuracy tests, the results showed that this tool functions well and accurately, with a very low average error value of 1.58%. This figure proves a high level of precision, making this tool suitable for use in the training process. In conclusion, this measuring tool can be an effective solution to support coaches and athletes in conducting kick evaluations objectively, measurably, and efficiently. In addition, this tool has great potential for further development with additional features in the future.

Abstract

BACKGROUND Dyslipidemia is characterized by an increase in low-density lipoprotein (LDL) and triglyceride (TG) levels and a decrease in high-density lipoprotein (HDL). Cholestyramine as an antidyslipidemia has several side effects, so an alternative is needed. Pectin is a natural substance with a mechanism of action similar to that of cholestyramine. Mango peel is one of the sources of pectin, containing 10–15% of this substance. This study aimed to prove the effect of arum manis mango (Mangifera indica L.) peel extract on LDL, HDL, and TG levels in dyslipidemic Sprague-Dawley rats. METHODS 25 Sprague-Dawley rats were divided into 5 groups. All groups were given high-fat diet for the first 18 days, followed by standard feed (negative control group), cholestyramine (Sequest®) 80 mg/200 g body weight (standard treatment group), and mango peel extract (M-90 [90 mg/day], M-180 [180 mg/day], and M-360 [360 mg/day] groups) for the next 15 days. LDL and HDL levels were analyzed using the cholesterol oxidase-phenyl aminopyrazolone method and TG level using the glycerol-3-phosphate-oxidase-phenol-aminophenazone method. RESULTS The M-360 group reduced the LDL level (p = 0.015), while the standard treatment group increased the HDL level (p = 0.042). Although significant TG level changes were found in the negative control, standard treatment, and M-360 groups (p = 0.042), the mean differences of LDL, HDL, and TG levels between groups were not significantly different (p = 0.245, 0.328, and 0.454, respectively). CONCLUSIONS M. indica peel extract reduced LDL and TG levels at 360 mg/day.
