Abstract. Aging naturally reduces physiology, increasing susceptibility to injuries, particularly in the knee joint, which supports substantial body weight and is vulnerable to osteoarthritis and ligament injuries. The current study investigates the effectiveness of leg muscle strength training in reducing knee pain intensity among elderly women aged 45 years and older residing in Gayamsari District, Semarang. A pre-experimental design employing a one-group pre-test post-test approach was implemented. Forty-two participants were selected using purposive sampling methods. The intervention involved leg muscle strengthening exercises conducted twice per week for six weeks, with each session lasting 40 minutes. Knee pain intensity was assessed using the Numerical Rating Scale both prior to and following the intervention. Data analysis was performed using the Wilcoxon signed ranks test due to non-normally distributed data. Findings indicated a statistically significant reduction in knee pain intensity, with average pre-test pain scores recorded at 3.2 ± 2.2 and average post-test scores recorded at 0.9 ± 1.4 (p = 0.000). Of the participants, 40 demonstrated a reduction in pain levels, whereas 2 participants showed no improvement, potentially influenced by additional medical conditions including gout and hypertension. In conclusion, leg muscle strength training significantly contributed to reducing knee pain intensity in elderly women, thereby justifying inclusion in rehabilitation programs targeting knee pain associated with osteoarthritis and ligament injuries. Further research is recommended to investigate tailored training protocols that account for co-morbid conditions and their impact on pain management efficacy.

This study aims to examine the effectiveness of the dual-processing method in improving the proportional thinking skills of 3T students in chemistry learning, especially in dealing with numeracy barriers. The dual-processing method refers to a cognitive theory that combines intuitive thinking (System 1) and analytical thinking (System 2) to improve students' conceptual understanding and numeracy skills. This study used a quantitative and qualitative approach with a pre-test and post-test experimental design and observation of student participation during the learning process. The results showed that after the dual-processing method intervention, there was a significant increase in students' numeracy skills, with an average post-test score increasing by 33.5 points compared to the pre-test. In addition, this method also helps reduce academic anxiety and increase students' confidence in solving numeracy problems. Classroom observations showed that students were more active in discussions and more reflective in solving chemistry problems than before the intervention. The dual-processing method has been proven effective in improving 3T students' numeracy understanding and overcoming proportional thinking barriers in chemistry learning. Therefore, the integration of this method into the higher education curriculum is recommended to improve students' critical and analytical thinking skills in numeracy-based disciplines.

Crude Palm Oil (CPO) contains ?-carotene as source of pro-vitamin A. Alternative adsorbent that can be used to adsorb ?-carotene is Palm Oil Fly Ash (POFA). This study aims to determine the ability of POFA activated with H3PO4 and Cu/Zn impregnation to adsorb ?-carotene from CPO to obtain characteristics data of modified POFA and its ability to adsorb ?-carotene. The main materials used were CPO and POFA. The parameters observed were the characterization and performance test of 9% H3PO4-activated POFA produced at various heating times for 90, 150, and 210 minutes with Cu/Zn impregnation. BET analysis showed the POFA with heating time of 90 minutes had the largest surface area of 19.4785 m2/g, XRD showed the presence of CuO, ZnO, quartz, and SiO2 diffraction patterns, FTIR showed that the POFA contained O-H groups, O-H, Si-H, Al-O, asymetric Si-O, and Si-O-Si bending vibrations, and SEM-EDX results showed that POFA has hollow pores and a rough spherical surface. Based on the results of UV-Vis Spectrophotometry analysis, the most optimal result was obtained in the ?-carotene adsorption process with POFA-modified 2 variations of activation heating time for 150 minutes, which succeeded in adsorbing 86% of ?-carotene.

In Indonesia, tapioca wastewater is one of the most abundant organic wastewater. It has a great deal of potential for use as a substrate for biogas, but it contains a high ratio of chemical oxygen demand (COD) to nitrogen (N). For this reason, adding nitrogen sources, such as urea, is crucial. Meanwhile, microbial electrolysis cell-assisted anaerobic digestion (MEC-AD) is a novel technology that can be applied to enhance biogas production. Thus, the purpose of this study was to ascertain how adding urea affected the biogas yield from tapioca wastewater through the MEC-AD process. There were six digesters, namely A (MEC-AD urea 0.25 g), B (MEC-AD urea 0.5 g), C (MEC-AD urea 1 g), D (MEC-AD urea 1.5 g), E (MEC-AD without urea), F (AD without urea). The MEC-AD process was carried out at room temperature using a batch system. The results revealed that the MEC-AD (without urea) generated a biogas yield 2.3-fold higher than AD alone (without urea). Then, an increase in urea addition in the MEC-AD process from 0 to 1.5 g enhanced biogas yield from 106.4 to 268.8 mL/g-COD. It means that in MEC-AD, the urea addition of 1.5 g generated 2.5 times more biogas yield than without urea addition. The MEC-AD with urea addition of 1.5 g had the most stable substrate pH and the highest volatile fatty acids during the process. The MEC-AD (without urea) gave a higher COD removal efficiency (21%) than AD alone (without urea), namely 14%. Then, an increase in urea addition from 0 to 1.5 g in MEC-AD increased COD removal from 21% to 38%. Therefore, the best variable was MEC-AD with a urea addition of 1.5 g. This innovation is expected to reduce environmental pollution and provide biogas as alternative energy to substitute the use of fossil fuels.    

This research aims to fill the knowledge gap by understanding that strategic resources such as collaboration networks, technology digitalization, and financial literacy contribute to improving performance through financial and business competencies and resilience in the perspective of a Resource-Based View (RBV). The study was conducted in Malang Raya, which has a dynamic agro-tourism area but is facing market pressure and high competition. It involved 50 chip MSME players who have been operating for at least two years. The research method uses the SEM-PLS on seven main variables: collaboration network, digitalization, financial literacy, competence, financial resilience, business resilience, and business performance. The results show that the three main resources have a significant effect on performance improvement, either directly or through strengthening competence and resilience. This research provides a theoretical contribution by expanding the application of RBV in the context of traditional food MSMEs, as well as presenting an integrative model to improve the competitiveness of MSMEs. Further research is recommended to explore external variables such as regulation and the dynamics of the growing digital market.

This study examines the influence of financial attitudes, financial literacy, and lifestyle on financial decision-making and financial well-being, with a focus on Generation Z. Utilizing a quantitative approach, data were collected from 306 respondents in West Sumatra through online surveys. The data were analysed using Structural Equation Modeling (SEM) with the Partial Least Squares (PLS) method, employing the Disjointed Two-Stage approach to ensure robustness and accuracy in testing the structural model. The results reveal that financial attitudes and financial literacy significantly enhance financial decision-making, which in turn positively influences financial well-being. Conversely, lifestyle exerts a negative influence on financial decision-making, thereby reducing financial well-being. Financial decision-making mediates the relationship between financial attitude, financial literacy and lifestyle toward financial well-being. This study contributes to the literature by integrating psychological, behavioural, and lifestyle dimensions into a unified model of financial well-being. It provides empirical evidence on the dominant role of financial attitude and the mediating mechanism of financial decision-making among digital-native populations. The findings suggest that targeted financial literacy interventions, value-oriented financial education, and lifestyle awareness programs are essential to foster sound financial decisions and improve financial well-being, especially for Generation Z.

After the Dutch colonial occupation, for 78 years Indonesia still used Wetboek van Strafrecht as the law that regulates criminal law until finally in 2023 Indonesia has a National Criminal Code. The National Criminal Code emphasizes the ultimum remedium character by changing fines into one of the main punishments. The formulation of fine as one of the main punishments is part of the effort to overcome the overcapacity in correctional institutions caused by imprisonment which has always been the main choice in the punishment system in Indonesia and is perceived increasingly ineffective. Fines that have been contained in the Criminal Code are also a reference for the determination of fines in special laws outside the Criminal Code, one of which is the Immigration Law which in its application faces many obstacles. This qualitative research uses normative juridical method that analyzes the norms of fine sanctions and its classification in the Indonesian National Criminal Code. Although there are still findings, the fine clause in the National Criminal Code raises new homework for legislators and implementers, related to special laws outside the National Criminal Code that also formulate fines in their criminal sanctions, the research found that the classification of fines in the National Criminal Code is formulated as a new Indonesian punishment policy that has a more ultimum remedium character and prioritizes the principle of justice over legal certainty, can be a guideline for imposing administrative fines for special laws and regulations such as Immigration Law

Increased textile industry production increases water pollution, especially rhodamine B dyes that are difficult to degrade. Global efforts to reduce water pollution through the adsorption process have been carried out with various adsorbents, the utilization of bottom ash from palm oil mill boiler combustion waste is still very minimal. This study examines the effect of contact time and bottom ash adsorbent mass on the adsorption capacity and absorption efficiency of rhodamine B using a fixed bed column adsorption process. The results showed that the longer the adsorption time, the higher the absorption efficiency. In the rhodamine B adsorption process, the best absorption efficiency was 98.308% at 10 cm bed height for 120 minutes and the best absorption capacity was 0.474 mg/g at 12 cm bed height for 150 minutes. The R2 price of Langmuir isotherm was 0.9999. FTIR analysis showed the presence of -OH, C-H, C=C and C-O functional groups that play a role in the adsorption process. The surface area of bottom ash from SAA test was 94.517 m2 /g. The SEM-EDX test analysis results had dominant elements of C, O and Si which showed good adsorption activity. From the results of the study that bottom ash from the combustion of oil palm mill boilers can be used as an effective adsorbent in reducing rhodamine B.
