Agnes Yunita Kirana — 2026-09-01

This applied study aims to analyze the impact of the Voluntary Disclosure Program (PPS) and tax sanctions on the compliance of individual taxpayers at the South Malang Primary Tax Office (KPP Pratama Malang Selatan). The study employs a quantitative approach using primary data collected via questionnaires from 100 individual taxpayers. The sample was selected using simple random sampling, and the data were analyzed through multiple linear regression using SPSS. The results indicate that the PPS does not have a significant effect on individual taxpayer compliance, whereas tax sanctions have a positive and significant effect. Simultaneously, both the PPS and tax sanctions significantly influence individual taxpayer compliance. The study recommends that the South Malang Primary Tax Office strengthen its outreach regarding the types and consequences of tax sanctions, alongside the consistent and proportional application of such sanctions. This approach should be implemented preventively—through notifications and education prior to obligation deadlines—followed by enforcement actions against taxpayers who fail to fulfill their obligations.

Rakhmad Maulidi — 2026-10-28

Bina Keluarga Lansia (BKL) groups in Purwokerto and surrounding areas have strong potential to develop productive activities through freshwater aquaculture. However, existing catfish farming practices remain largely traditional and lack measurable water quality management, resulting in suboptimal yields and limited income generation. This community service program aimed to strengthen the capacity of productive elderly groups by applying a Recirculating Aquaculture System (RAS) integrated with the Internet of Things (IoT). The system combines a culture pond with a separate upflow drum filter consisting of sedimentation, mechanical, chemical, and biological filtration zones. IoT integration employs pH and turbidity sensors to monitor water quality, control water circulation, and detect sediment accumulation for timely sludge removal. The program was implemented through socialization, technical training, system assembly and installation, operational assistance, and evaluation. The results showed improved knowledge and skills among elderly participants in modern catfish farming, more stable pond water quality, improved fish survival, and the potential for more consistent, market-oriented production. The program provides a sustainable, technology-based empowerment model for productive elderly groups that is practical, replicable, and applicable to similar urban community development initiatives.

Anissa Fauzia Isyanti — 2026-10-28

This community service activity aimed to enhance the digital marketing capacity of Mamochi MSME, a culinary business producing and selling mochi in Purwokerto, through the development and implementation of a website-based ordering system. Prior to the program, product promotion and ordering processes were conducted manually through social media and direct messaging, limiting marketing reach and customer access to product information. The implementation method consisted of observation and interviews to identify partner needs, website design and development, website management training, and user satisfaction evaluation. The developed website provides product catalogs, galleries, business information, location maps, social media integration, and an ordering feature connected to WhatsApp. Following implementation, training sessions were conducted to enable the business owner to independently manage website content and product information. Evaluation results from 10 respondents indicated a high level of satisfaction, with 30% strongly agreeing, 68% agreeing, and 2% moderately agreeing regarding the usability and benefits of the website. The activity demonstrates that the utilization of a website as a digital marketing platform can improve promotional effectiveness, simplify the ordering process, and support the digital transformation and competitiveness of MSMEs in an increasingly digital business environment.

Optimizing the Production of Banyuwangi-Style Bagelan Bread MSMEs through the Application of Appropriate Technology and Sustainable Marketing

Charis Fathul Hadi — 2026-10-28

This community service initiative aims to enhance the production capacity and efficiency of the bread and pastry business owned by Mrs. Kavi Nirmala in Temenggungan Village, Banyuwangi Regency, East Java, through the implementation of a dough-mixing technology integrated with divider and rounder systems. The partner faced challenges due to a manual production process that was labor-intensive, time-consuming, and resulted in inconsistent dough portioning.

The implementation method involved problem identification, equipment design and fabrication, outreach, operational training, and ongoing assistance alongside performance evaluation. The implemented technology integrates the dough mixing, dividing, and rounding processes into a single workflow. Results indicate that the technology increased dough processing capacity from 3 kg to 6 kg per batch. Production frequency also rose from three to six batches daily, representing a 100% increase. Beyond boosting production capacity, the technology reduced the manual workload and ensured greater uniformity in dough portion sizes. Consequently, the adoption of the integrated mixer, divider, and rounder system has positively impacted productivity, process efficiency, and the partner's capacity to expand their *bagelan* bread business.

Diversifying Virgin Coconut Oil into Solid Soap with Betel and Zodia Extracts in Skow Mabo

Ilham Salim — 2026-10-28

The Usaha Cemerlang group in Skow Mabo produced virgin coconut oil (VCO), but product turnover and diversification remained limited. This community-engagement program aimed to strengthen the group's capacity to produce and market solid VCO soap containing betel and zodia leaf extracts. The program comprised problem identification, safety orientation, hands-on production, molding, 24-hour demolding, a minimum four-week curing period, packaging, marketing, and evaluation. Ten members participated in activities on 4 and 12 June 2026, followed by monitoring on 18 August 2026. Achievement was assessed through direct observation, production records, laboratory testing at Universitas Cenderawasih, and sales monitoring. The cured soap had a pH of 9 and free alkali of 0.07%, below the 0.1% maximum cited in SNI 3532:2021. One production cycle yielded 32 bars in 30 minutes with two workers; seven cycles produced a theoretical 224 bars, so a conservative capacity of 200 bars per five-hour working session was adopted. Production cost was IDR7,000 and selling price IDR13,000 per bar, giving a gross margin of IDR6,000 per bar. The first order of 12 bars sold out, followed by recurring 12-bar orders every one to two weeks at one outlet. The program established a sequential production-to-market workflow and produced measurable technical and economic outcomes, although longer sales records and broader product-safety testing remain necessary.
