The main objective of this study is to analyze the effect of the FDM process parameters on the printing time and socket weight of the printed socket prosthetic process as a component of the transtibial prosthesis. Optimization and modeling of the 3D printing prosthetic socket process were carried out using the Taguchi and RSM methods. The Taguchi method was used to evaluate the influence of various factors (socket thickness, layer height, infill density, print speed, and nozzle temperature) on the amount of printing time and socket weight. Furthermore, the factors that have a significant effect are selected and modeled using the RSM method to obtain the highest percentage of printing time and socket weight. The applied material is polylactic acid (PLA) filament. Five printing process parameters were socket thickness (3 mm, 4 mm, 5 mm), layer height (0.1 mm, 0.15 mm, 0.3 mm), infill density (80 %, 90 %, 100 %), print speed (70 mm/s, 80 mm/s, 90 mm/s) and nozzle temperature (190 ◦C, 200 ◦C, 210 ◦C). The proposed quadratic models for reducing both printing time and socket weight were in good accordance with the actual experimental data. The coefficients of determination (R2) for test data were 0.9743 and 0.9993 for printing time and socket weight, respectively.

The ankle foot prosthesis is of the energy storing type with Al 6061 material. The experimental design employed the Box Behnken technique, with four factors and three levels for each factor, and machining time as a response. The machining parameters assessed in this study are spindle speed, feed rate, step-over, and toolpath technique. The physical trials were carried out using a threeaxis CNC milling machine with a flat endmill cutting tool (diameter 5.5 mm, 2 flute with HSS material). The experiment outcomes were assessed using variance analysis, graphs, and numerical approaches. The response surface method (RSM) calculates the mathematical model of the ideal cutting combination parameters based on machining time. Based on the findings, the ideal cutting parameters in the ankle-foot prosthesis production process on a CNC milling machine were spindle speed of 6500 rpm, feed rate of 800 m/min, step over of 0.2 mm, and flowline toolpath strategy. To establish the machining time value of the ankle-foot prosthesis, the ideal circumstances were identified. The findings of this study revealed that CNC milling gave the quickest time for machining transtibial prosthesis components, which can be used to guide the development of machining methods for ankle-foot prostheses constructed of Al 6061 material. The optimal machining time is 424.4601 min.

Mental toughness must be identified during athlete practice preparation to help to keep athletes appropriate while they encounter difficulty in a match or under pressure during the competition, and use intervention measures so that they do not become stressed quickly. The study aimed to develop a tool to detect the mental toughness of athletes and validate its psychometric properties. The participants included 218 athletes from Bekasi, Indonesia. The data were collected via online form randomly. Rasch analysis was utilized to evaluate the validity and reliability of the mental toughness questionnaire in the Indonesian version. Item fit criteria were assessed based on Rasch parameters. The rating scale function was performed to check how well the participants comprehend the rating scale categories in the Mental Toughness Questionnaire. The results show that the mental toughness questionnaire in the Indonesian version achieves the validity and reliability criteria based on Rasch parameters. All items fit based on threshold item fit in the Rasch parameter, and we confirm that three rating scales are better than four rating scales.

Based on the results of field observations, it was found that the main problem in the drainage of the Rawa Indah hamlet is the accumulation of garbage in the drainage channel which hampers drainage performance, so it is necessary to clean, handle, and maintain the channel so that the drainage system can work properly. Community service activities by conducting socialization and directing the implementation of activities, how to clean / reactivate / repair drainage channels, and how to determine the tools used to suit the needs. As a result of this activity, the community has learned how to activate or repair drainage channels so that drainage canals function normally.

To prove the effectiveness of arm muscle strength training using tennis in martial arts athletes at the Sriwijaya State Sports School was the purpose of this study. The experimental method with a pretest-posttest control group design was used. The experimental group (E G) performed arm muscle strength training using tennis balls with a frequency of 6 times a week for 1 month. The control group (C G) did arm muscle strength training by means of push-up only without using variations of movement or (conventional) equipment with the same frequency as the experimental group. The subjects in this study were 50 martial arts athletes aged 14-17 years which consisted of 10 pencak silat athletes, 7 judo athletes, 9 taekwondo athletes, 7 karate athletes, 10 wrestling athletes and 7 wushu athletes, separated into 2 groups, E G (n=25) and C G (n=25).The instruments used in the study were: 1 minute push-up assisted by the Fikri Muscle Strength Test application. Data analysis in this study used the statistical method paired sample t-test and independent sample t-test using SPSS 21 to see the effectiveness of arm muscle strength training using a tennis ball. The results of data analysis showed that there was a higher increase in the E G than the C G with the mean difference in push-up data of 3.84. The findings of this study are that the exercise variation developed is more effective than conventional exercise and the developed test instrument can help to calculate the results of the push-up test.

In the athlete rehearsal preparation, mental toughness condition needs to be identified to keep the athletes fit when they have some difficulties in a match, feel the pressure during the match, and take behavior control, so that they will not get stressed easily. This study aims to find whether age, gender, and match experience affect the athlete's mental toughness. The study was done to 174 (age = 19.69 ± 2.89) martial art athletes in Bekasi who were preparing themselves for a province/regional level match (PORPROV West Java 2022). Instrument of mental toughness refers to mental toughness dimension namely: control, commitment, challenge, and confidence. Data were analysed by using multiple logistic regression and cross tab. The result shows that mental toughness of martial art athletes was influenced by gender and match experience. Most of them are on the high level of mental toughness, and the majority is the men at the age of 19 to 22 who have experience in doing a national match. In addition, the relationship observed in this study emphasizes the need of coping and optimism training in mental toughness intervention.
