This study aims to determine the effect of varying hybrid composite volume fractions of luffa (Luffa cylindrica) fiber and fiberglass on the tensile strength of the material. The composite matrix used was polyester resin, while the reinforcements consisted of luffa fibers treated with 5% KOH alkaline solution to improve adhesion with the matrix, and fiberglass as an additional strengthening material. The composition variations applied in this research were 90%:5%:5%, 85%:7.5%:7.5%, and 80%:10%:10% (polyester resin : luffa fiber : fiberglass). The fabrication process was carried out using the hand lay-up method, which is widely used for producing layered composites, followed by tensile testing according to standard mechanical testing procedures to evaluate tensile strength and elongation. The results showed that the addition of luffa fiber and fiberglass fractions had a significant influence on the mechanical properties of the composites. The 80%:10%:10% variation demonstrated the highest tensile strength value of 13.65 MPa and the highest elongation of 0.0105%, indicating better mechanical performance compared to other variations. These findings confirm that the hybridization of natural luffa fiber and synthetic fiberglass can work synergistically to improve the tensile strength of the composite. However, higher fiber fractions should be considered carefully, as they may affect the homogeneity of the mixture and the quality of interfacial bonding. Further research is recommended to optimize volume fractions, enhance fiber surface treatments, and evaluate additional mechanical properties such as impact strength and hardness, in order to explore the potential of hybrid composites as eco-friendly materials with promising mechanical performance.

This study analyzes the potential use of cockle shell waste and coal fly ash as alternative raw materials in the production of composite brake pads. The high volume of industrial and fisheries waste, which has not been optimally utilized, encourages the exploration of environmentally friendly materials with adequate mechanical performance. The main focus of this research is the compressive strength of the produced brake pads, as this parameter is crucial for ensuring effective and safe braking performance. The method used includes the mixing and molding of composite materials with varying compositions of cockle shell and fly ash, followed by compressive strength testing according to standards. This study also takes into account the environmental impact of using waste as filler material, which is expected to reduce reliance on conventional materials and decrease waste that contaminates the environment. The results of the study are expected to provide empirical data on the potential of these two wastes as fillers in brake pad matrices and to identify the optimal formulation that provides the highest compressive strength. This study contributes to the development of sustainable braking materials and efforts to mitigate the environmental impact of waste, while also opening opportunities for the reuse of waste that has previously been poorly managed.

Postoperative Total Knee Replacement (TKR) patients often face various clinical problems, including quadriceps muscle weakness, limited range of motion of the knee joint, swelling, and pain that can have a significant impact on functional movement ability, independence of daily activities, and overall quality of life. The condition demands the role of the physiotherapist in providing appropriate and comprehensive interventions to facilitate the patient's recovery. One approach that can be done is to provide a combination of Neuromuscular Electrical Stimulation (NMES) modalities and exercise therapy. This study aims to evaluate the benefits of NMES and exercise therapy combination interventions in improving quadriceps muscle strength, knee joint range of motion, and functional mobility ability in post-TKR patients. The research design used a case study method involving three patients who were in phase 2 (motion phase), namely 3 days to 6 weeks after TKR surgery. Patients show complaints in the form of weakness of the quadriceps muscles, limited range of joint movement, and decreased knee function function. Physiotherapy interventions were given as many as 8 meeting sessions with a frequency of 2 times a week. The intervention program consisted of administering NMES to the quadriceps muscle and functional exercises such as sit to stand exercise, gait training, strengthening exercises using resistance bands in the ankle joint, and stair climbing. The results showed a significant increase in quadriceps muscle strength, an increase in the range of motion of the knee joint, and an improvement in functional movement ability after all intervention sessions were completed. These findings confirm that the combination of NMES with exercise therapy can be an effective rehabilitation strategy for post-TKR patients. The implementation of this method has the potential to speed up recovery, reduce dependence on others, and improve the patient's quality of life in a sustainable manner.

Athletic physical condition is a key factor in determining an athlete's performance during competitions. This study aims to assess the physical condition of Unesa Women FC athletes using a descriptive quantitative method, involving 20 athletes as the sample. Data was collected through a series of physical tests to measure various aspects of physical fitness, including aerobic endurance, speed, agility, leg strength, and explosive power. The tests conducted included the Multistage Fitness Test (MFT) for aerobic endurance, a 30-meter sprint for speed, Illinois Agility Run for agility, Leg Dynamometer for leg strength, and Jump MD for explosive power. The results of the study show that the average VO2Max of the athletes is 30.8 ml/kg/min, which falls into the "Poor" category. This indicates that the athletes' aerobic endurance has not yet reached the optimal standard required for competitive performance. The 30-meter sprint time recorded was 5.53 seconds, categorized as "Good," indicating that the athletes have adequate speed. However, the agility score obtained from the Illinois Agility Run was 21.97 seconds, classified as "Poor," suggesting that the athletes need to improve their agility for quicker movements on the field. The explosive power score, measured by the Jump MD test, was 45.75 cm, which also falls into the "Poor" category, while leg strength, measured using the Leg Dynamometer, resulted in a score of 57.47 kg, classified as "Very Poor." These findings indicate that most components of the physical condition of the Unesa Women FC athletes are still below optimal levels. Therefore, the study emphasizes the need for a more structured and targeted physical training program tailored to the individual needs of each athlete. A training program designed based on these test results will help improve the physical fitness components that are lacking and support the enhancement of their performance during competitions.

A fiduciary guarantee agreement is a formal agreement that must be stated in a notarial deed as regulated in Article 4 of the Fiduciary Guarantee Law. This provision states that a fiduciary guarantee is a subsidiary agreement of the main agreement that creates an obligation for the parties to fulfill a performance. Execution, in this context, is a legal action carried out based on a legally binding decision. Article 15 paragraph (2) of the Fiduciary Law explains that the executorial power of a fiduciary guarantee certificate allows for direct implementation without going through a court, is final, and binds the parties. This research uses an empirical normative method, namely combining library studies with field research. Primary data was obtained through interviews with Judges of the Yogyakarta District Court, Judges of the Sleman District Court, the Yogyakarta State Assets and Auction Service Office (KPKNL), and the Yogyakarta Regional Office of the Ministry of Law and Human Rights. Secondary data comes from primary, secondary, and tertiary legal materials. The analysis was conducted qualitatively. The research results indicate that following Constitutional Court Decision No. 18/PUU-XVII/2019, the execution of fiduciary collateral objects can no longer be carried out unilaterally by creditors, but must instead be filed through the District Court. This provision balances the legal standing between debtors and creditors and prevents potential arbitrariness. Nevertheless, execution through the courts is an alternative if there is no agreement between the parties regarding a default. The court's role following the Constitutional Court decision includes resolving disputes between creditors and debtors and ensuring that execution procedures are carried out in accordance with the HIR (Regional Regulations for the Protection of Creditors), RBG (Regional Regulations for the Protection of Creditors), and the Supreme Court's technical instructions. In general, the execution mechanism through the courts is considered quite effective in ensuring legal protection for both parties.

Welding is one of the most essential metal joining processes in manufacturing, construction, and industrial applications, where Shielded Metal Arc Welding (SMAW) remains widely used due to its flexibility, cost-effectiveness, and ability to be applied in various welding positions. This study aims to analyze the effect of welding position variations on the mechanical properties of SS400 steel, particularly in terms of tensile strength, bending strength, and microstructural characteristics. The experimental method was conducted using 6 mm thick SS400 steel with E6013 electrodes of 2.6 mm diameter in three welding positions: 1G, 2G, and 3G. The welded specimens were then tested through tensile testing (ASTM E8) and bending testing (ASTM E190-14), followed by microstructural analysis in the weld metal area. The results revealed that welding position significantly affects the mechanical properties of welded joints, where the 3G position produced the highest tensile strength of 188.48 kgf/mm², while the 2G position produced the lowest tensile strength of 113.70 kgf/mm². Conversely, the bending test showed that the 2G position provided the maximum bending strength of 1394 kgf/mm², followed by 3G and 1G positions. Microstructural observations demonstrated variations in the distribution of ferrite, pearlite, martensite, and cementite phases across different welding positions, with the dominance of ferrite and pearlite in the 3G specimen contributing to higher tensile strength, while the dominance of martensite and cementite in the 2G specimen enhanced hardness and bending resistance. Overall, this study confirms that welding position plays a crucial role in determining the quality of SS400 welded joints, and the findings are expected to serve as practical guidance for industry in selecting appropriate welding positions for construction needs, while encouraging further research with additional variables such as electrode type, welding current, and post-weld heat treatment to achieve a more comprehensive understanding.

The development of construction materials is currently very rapid, including in the manufacture of fishing boats that still use wood. As an alternative, High Density Polyethylene (HDPE) plastic can replace wood because of its various advantages. The process of making fishing boats uses the plastic welding method, where the material is heated close to the melting temperature with a welding gun. The welding rod melts due to heat and is pressed continuously while the welding gun moves backward. This study aims to determine the effect of variations in the hot gas welding process on mechanical tests, especially bending tests on plastic welding joints. The two independent variables used are the hot gun temperature (250°C, 300°C, and 350°C) and the V bevel angle (60°, 75°, and 90°). The five controlled variables include the anvil temperature of 150°C, 3,2 mm thick HDPE plastic sheet, hot gas speed welding method, 5 mm diameter HDPE plastic additives, 7 liters/minute air flow rate, 1.2 mm/s welding speed, and 2 mm root gap. The research results are expected to obtain the maximum value of the bending test strength from the interaction of hot gun temperature variations and V-beam angles, as well as being a reference in making fishing boat bodies from HDPE using the hot gas welding method.

  Alumunium AA1100 is widely used in flat plate products such as heat exchanger fins and lightweight structural panels, yet it’s welding process still requires optimization. This study aims to determine the effect of tool traverse speed and backing plate preheating temperature on the bending strength of AA1100 joints produced by Friction Stir Welding (FSW). Experiments were conducted at three levels of each factor with three replications per combination: traverse speeds of 10 mm/min, 20 mm/min, 30 mm/min, and preheating temperatures of 200 °C, 250 °C, 300 °C. Results showed the travers speed, preheating temperature, and their interaction all had significant effects on bending strength (P-Value < 0,05). The optimal combination 30 mm/min traverse speed and 200 °C preheating yielded a bending strength of 238,95 Mpa. The regression model’s coefficient of determination was 97,16%, indicating an exellent fit. Thus, selecting the right FSW parameters can significanly enhancejoint quality.

Instruments included a push-up test to measure arm muscle strength, a V-sit and reach test for back muscle flexibility, a one-leg balance test, and a throwing and catching test using a softball. The results is arm muscle strength had a significant relationship with throwing and catching skills (Pearson correlation value of r = 0.921 (p < 0.05)). In contrast, back muscle flexibility (r = 0.328) and balance (r = 0.131) did not show significant relationships. The conclution arm muscle strength is most influential factor in determining throwing and catching in children, therefore, training programs should prioritize arm strength development to support motor skill advancement in early age.

This study aims to analyze the effect of audit quality, earnings power, and risk-taking behavior on firm performance, while also testing the moderating role of the risk management committee. The research was conducted on 18 mining companies listed on the Indonesia Stock Exchange (IDX) during the 2019–2023 period. A quantitative approach was employed using moderated regression analysis (MRA). The results show that only earnings power has a positive and significant effect on firm performance, whereas audit quality and risk-taking behavior have no significant effect. Additionally, the risk management committee strengthens the influence of audit quality on firm performance but does not moderate the relationship between earnings power or risk-taking behavior and performance. These findings suggest that internal oversight through the risk management committee is only effective in the context of audit but not yet optimal in managing earnings or risk-taking. This study contributes to corporate governance literature in the mining sector by emphasizing the importance of an active and strategic risk management committee.

This study aims to explain the strength of social capital owned by Nurdin in political contestation in 2016. This type of research is a descriptive qualitative study to explore the strength of social capital in the transformation of village head leadership. Meanwhile, the approach used is the phenomenological approach The results of this study indicate that the previous leadership style that the author limits only captures the leadership style for the period 2002-2009. During the 2002-2004 period, when Karaeng Oddang was in charge, in his leadership he tried to be more democratic, but the domination of his father (Karaeng Manna) was still strong at that time. Likewise with Aji Awaluddin 's karaeng leadership style, he was a typical leader who was considered by the community to be very good and realized democratic values ​​during his tenure as head of Kindang village for the 2004-2009 period. In 2009-2016, this was where leadership transformation took place. Photographing Nurdin's leadership style for the period of 2009 cannot be separated from appreciation and praise. However, this criticism did not have an impact on the 2016 village head election. Nurdin won the pilkades again.  Nurdin's strength of social capital in the election has won him victory. The rise of primordial sentiment among ordinary people (tumaradeka) as Nurdin's strength, and on the other hand the rise of negative stereotypes against karaeng that spread to the issue of group identity and the strong strength of social networking capital, bonding, bridging and linking greatly colored the 2016 pilakdes. Social capital security control is a selling point for Nurdin so that he can get support from the community compared to other candidates who are deemed unfit and unable to anticipate security in Kindang village.

Integrated assessment is a multidisciplinary approach used in the judicial system to evaluate the psychological, social and medical conditions of legal subjects, particularly in cases involving children, victims of violence, persons with mental disabilities or defendants with psychological disorders. This study aims to examine the evidentiary strength of integrated assessment from juridical and psychological perspectives using a normative juridical approach. The findings reveal that although integrated assessments are recognized in legal practice, their status as admissible evidence is not yet explicitly regulated in criminal procedural law. From a psychological perspective, such assessments possess high scientific value and can provide an objective overview of the subject’s condition. However, limited understanding among legal practitioners regarding the interpretation of assessment results remains a major challenge. Therefore, regulatory harmonization and cross-sectoral capacity building are needed to optimize the function of integrated assessments in court proceedings.
