Abstract

This community service project aims to design the Al-Qur'an Education Park (TPQ) at the At-Taqwa Mosque, Kebon Batur Village, Demak, to provide facilities that support religious education for local children. The At-Taqwa Mosque was chosen as the location because it plays an important role in religious development in the area, but currently still has limited facilities to support adequate TPQ activities. Through a participatory approach involving the local community, discussions, field observations, and designs based on educational building standards were carried out. The result of this activity is a safe, functional, and environmentally friendly TPQ design, which is expected to be a guideline for the development of sustainable religious education facilities.

Abstract

The Route modification for the Trans Semarang feeder line 1 resulted in the creation of feeder line 1A. To evaluate the effectiveness of this change in addressing critical community needs, an analysis was conducted. This study utilized passenger boarding and alighting data obtained through origin-destination surveys, combined with land use data from the Google Earth application. Findings revealed inconsistencies and fluctuations when comparing passenger movement patterns with land use values. The feeder transportation function was deemed effective, with the highest proportion of passengers (23.53%) boarding at the transit shelter. Conversely, the segment between Jalan Perkebunan and Desa Ngadirgo shelters exhibited the lowest passenger volume, attributed to long distances between shelters, extensive forested and plantation areas, and a one-way route. These factors suggest potential benefits of rerouting. Further research is recommended to comprehensively evaluate the broader implications of such modifications.

Abstract

The implementation of pilot Bus Rapid Transit (BRT) systems in metropolitan agglomerations, such as Trans Jateng, plays a pivotal role in providing affordable public transportation, enhancing regional connectivity, and fulfilling Minimum Service Standards (MSS). This study evaluates the operational performance of two specific Trans Jateng corridors: Corridor 1 (Semarang – Bawen) and Corridor 6 (Semarang – Grobogan). The primary focus of this research is the analysis of time-series load factor data to assess bus performance. Data were gathered through on-board surveys utilizing Global Positioning System (GPS) devices and structured survey instruments. The data collection was conducted over a period of two weekdays and one weekend day. The analytical results indicate that both corridors experience significant kelebihan penumpang during peak hours, with load factors exceeding 170% in Corridor 1 and 110% in Corridor 6. Furthermore, this study identifies distinct fluctuations in passenger demand patterns between weekdays and weekends, as well as variations between individual trips within the same corridor. The findings reveal a notable disparity in average load factors. In Corridor 1 during weekdays, the load factor for the Semarang – Bawen route was 55.73%, while the Bawen – Semarang route reached 38.81%; on weekends, these figures shifted to 60.46% and 40.03%, respectively. In Corridor 6, the weekday load factor for the Semarang – Godong route was 46.05% and 39.25% for the reverse direction, whereas weekend figures were recorded at 51.49% and 34.68%. Given that the ideal minimum load factor is 70%, more systematic operational management is necessitated to maintain optimal service performance. Proposed recommendations include the dynamic adjustment of fleet size to align with demand levels—particularly during peak periods—and the implementation of more adaptive capacity management strategies. Such measures are intended to regulate load factors during high-demand intervals, enhance passenger comfort, and improve the overall operational efficiency of the transit service.

Abstract

Improving the quality of teachers must and must always be improved in order to support learning activities in schools, especially geography teachers. In geography subjects, teachers must be able to teach students directly how to make thematic maps digitally, therefore, learning in class is not only limited to theory but also directly practiced so that students can understand more easily and learning in class becomes effective. However, the conditions in the field are that teachers still experience difficulties and obstacles in teaching students how to practice making maps digitally using software. One of the obstacles faced by teachers is because the price of the software is so expensive, therefore our community service team tries to use free software (open source), namely Quantum GIS (QGIS). The development of geographic information system technology, especially software, is developing very rapidly and quickly. therefore it is important for teachers to be able to follow technological developments in the field of geographic information systems, especially Quantum GIS (QGIS) software. This community service activity aims to improve practical skills and also update the development of geographic information system technology, especially using Quantum GIS (QGIS) software in the geography teacher group in the Madrasah Aliyah environment in Batang Regency. The activity will be carried out in the form of socialization to provide knowledge for geography teachers regarding updates on the development of geographic information system technology, as well as workshop activities and practical training in data processing and digital map making using Quantum GIS (QGIS) software..Peningkatan kualitas guru harus dan wajib selalu ditingkatkan dalam rangka mendukung kegiatan pembelajaran disekolah dalam hal ini khususnya guru geografi. Pada mata pelajaran geografi guru harus mampu mengajarkan kepada siswa secara langsung bagaimana cara membuat peta tematik secara digital oleh karena itu pembelajaran dikelas bukan hanya sebatas teori namun juga langsung dipraktikan sehingga siswa lebih mudah memahami dan pembelajaran dikelas menjadi efektif. Namun kondisi dilapangan faktanya para guru masih mengalami kesusahan dan kendala dalam mengajarkan kepada siswa bagaimana praktik membuat peta secara digital menggunakan software. Kendala yag dihadapi guru salah satunya adalah karena harga software yang begitu mahal, oleh karena itu kami tim pengabdi mencoba untuk menggunakan software yang tidak berbayar (opensource) yaitu Quantum GIS (QGIS) Perkembangangan teknologi sistem informasi geografis khususnya pada software sangat berkembang pesat dan cepat. oleh karena itu hal ini menjadi penting bagi guru untuk dapat mengikuti perkembangan teknologi dibidang sistem informasi geografis khususnya software Quantum GIS (QGIS) . Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan keterampilan praktek dan juga update perkembangan teknologi sistem informasi geografis khususnya menggunakan software Quantum GIS (QGIS) pada kelompok guru geografi di lingkungan Madrasah Aliyah di Kabupaten Batang. Kegiatan akan dilaksanakan dalam bentuk sosialisasi untuk memberikan pengetahuan bagi guru-guru geografi terkait update perkembangan teknologi sistem informasi geografis, serta kegiatan workshop dan pelatihan praktek pengolahan data dan pembuatan peta digital menggunakan software Quantum GIS (QGIS).

Abstract

Pilangsari Village in Kendal Regency has an annual shrimp catch potential of 5–10 tons, with part of it processed into shrimp paste by the Coastal Women’s Group consisting of 30 members. The main challenge is the traditional drying process, which takes up to a week and depends heavily on weather conditions, along with ziplock packaging that does not fully seal, leading to rapid quality degradation. This community service activity aims to improve production efficiency through the adoption of appropriate technologies, including a dehydrator and food-grade vacuum packaging. The approach involves coordination, needs assessment, training on equipment use, and ongoing technical support. Results show an expected 80% increase in production capacity and efficiency, along with improvements in skills and product quality. The program aims to reduce weather dependency, extend shelf life, and support sustainable economic independence for coastal communities.

Abstract

In the contemporary e-commerce ecosystem, delivery lead-time efficiency serves as a critical determinant of customer satisfaction. This study investigates the distributional characteristics of delivery durations for the "SPX Standard" service across four operational configurations: Early-Week Double-Day (peak), Weekend Double-Day (not available), Early-Week Non-Double-Day, and Weekend Non-Double-Day. Utilizing a quantitative comparative Exploratory Data Analysis (EDA) framework, historical logistics data were synthesized from 509 Shopee users in the Gunung Pati District, Semarang, spanning the 2024–2025 period. Statistical computation conducted via RStudio revealed significant departures from normality, as confirmed by Kolmogorov-Smirnov and Shapiro-Wilk tests (p<0.05). Consequently, hypothesis testing was performed using the non-parametric Kruskal-Wallis H-test. The analysis identified significant variance in median delivery velocities across groups (χ2=6.4256; p=0.04024). Findings indicate that while the Early-Week Non-Double-Day configuration recorded the highest median velocity (6 km/h), it exhibited extreme data dispersion, signaling process instability. Conversely, the Early-Week Double-Day period demonstrated superior reliability characterized by low variability, reflecting the efficacy of capacity scaling strategies during peak demand. The lowest performance metrics were observed during weekends, suggesting localized operational constraints. This research concludes that while peak-load operational stability effectively mitigates service degradation risks, standardized processes during regular workdays require further optimization. Limitations include the exclusion of holiday-related freight restrictions (e.g., Eid al-Fitr and Year-End periods).
