Electronic money laundering has become a critical issue as a form of cybercrime. Advances in technology demonstrate that digital forensic applications, particularly those utilizing smartphones, can be employed to uncover digital traces of money laundering transactions. This study aims to analyze the relevance of existing legal frameworks, the effectiveness of smartphone forensic techniques, and the challenges faced in their implementation in Indonesia. Based on a review of the literature and regulatory analysis, it was found that legal frameworks such as UU No. 8 of 2010 on the Prevention and Eradication of Money Laundering (TPPU) and UU No. 19 of 2016 on Information and Electronic Transactions (ITE) provide an adequate legal foundation. However, gaps in implementation, such as limited human and technological resources, remain significant obstacles. Forensic techniques, including metadata analysis and device extraction, have shown great potential in identifying the flow of illicit funds. Nonetheless, their application is hindered by data confidentiality and the lack of uniform technical standards. Given the increasing complexity of digital crimes, an integrated approach is required, combining regulatory strengthening with technological capacity building, to enhance the effectiveness of smartphone forensics in addressing electronic money laundering.

This study investigates how teaching methods affect students' willingness to learn. Students' interest and engagement in the learning process can be enhanced by effective teaching methods. Different teaching philosophies, including collaborative, inventive, interactive, and authoritative, have varying effects on students' willingness to learn. To achieve the best learning outcomes, it is necessary to choose a teaching style that suits the needs and characteristics of students. In this study, a qualitative approach was used to analyze students' perceptions of various teaching styles in the classroom environment. The results showed that interactive and collaborative methods tend to increase learning motivation more than the one-way authoritative style. In addition, teacher emotional involvement, the use of interesting learning media, and a conducive classroom atmosphere also contribute greatly to shaping students' learning interests. These findings are expected to be a reference in designing more adaptive and effective teaching strategies.

Measurement of vitamin C and phenolic content was done using UV-Vis spectrophotometric method. The results showed that the addition of grape leaf extract significantly increased the vitamin C content of grapes both on day 0 and day 7, with the highest level found in the 5% treatment. Phenolic content increased at 3% concentration on day 0 but decreased at 3% concentration on day 7. Two Way Anova statistical test showed a significant effect of extract concentration and storage time on vitamin C and phenolic content. The addition of grape leaf extract into chitosan edible coating was effective in maintaining vitamin C and phenolic content and extending the shelf life of grapes at room temperature. These findings support the potential use of natural materials as plant-based preservatives in food coating systems.

This study aims to identify forms of violations of the right to health services in the implementation of BPJS Kesehatan, analyze the factors that cause them, and formulate preventive and limiting solutions. The research used a descriptive qualitative approach with in-depth interviews with six informants who were active BPJS Health participants in Tanjung Sari, East Jambi. The results showed that there was service discrimination in the form of different treatment between BPJS patients and general patients, patient rejection, administrative obstacles in emergency situations, and unavailability of drugs and medical facilities. Contributing factors include unequal distribution of health facilities, limited human resources, and a weak monitoring system. The experiences of BPJS participants confirm the gap between the program's objectives and the reality on the ground, reflecting a denial of the state's obligation to guarantee citizens' health rights. Comprehensive efforts are needed, including public education, administrative simplification, equitable distribution of health facilities, enforcement of strict sanctions, and active community involvement to realize quality and equitable health services.

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.    

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.
