Abstract

This community service project addresses the high operational costs of Litopenaeus vannamei cultivation by implementing a hybrid power system combining a venturi wind turbine and solar panels. The methodology utilizes the Plan-Do-Check-Act (PDCA) cycle to ensure active community participation and promote technology adoption, which is a key factor for the program's long-term success and sustainability. Economically, this implementation resulted in substantial benefits, demonstrating a 36.47% decrease in fuel expenses (Rp 1,399,000) and an overall operational cost efficiency of Rp 4,021,500. This efficiency effectively improved aquaculture profitability, with profit increasing from Rp 15,071,938 to Rp 15,969,750. Thus, the project offers a concrete, efficient, sustainable, and environmentally friendly solution for shrimp cultivation.

Abstract

Penelitian ini bertujuan untuk mengkaji penerapan metode pembelajaran eksperimen terhadap keterampilan proses sains siswa di SMA Negeri 1 Purbolinggo. Metode eksperimen diterapkan dalam tiga tahap kegiatan: persiapan, pelaksanaan, dan tindak lanjut eksperimen. Hasil penelitian ini menunjukkan bahwa penerapan metode ini secara signifikan meningkatkan keterampilan siswa dalam mengamati, mengklasifikasikan, menggunakan alat, mengkomunikasikan data, dan menyimpulkan hasil percobaan. Selama uji untuk kerja, siswa yang mendapat pembelajaran eksperimen sebelumnya menunjukkan performa yang lebih baik dibandingkan siswa kelas kontrol di semua indikator keterampilan proses sains. Peningkatan paling signifikan terlihat pada keterampilan mengobservasi dan mengklasifikasi, yang menunjukkan efektivitas kegiatan praktikum terstruktur dalam mendukung pemahaman konsep fisika. Penelitian ini menegaskan bahwa metode eksperimen tidak hanya meningkatkan pemahaman konseptual siswa tetapi juga keterampilan praktis yang esensial dalam pembelajaran berbasis ilmiah.

Abstract

This study synthesized Ni-doped ZnO (Ni0.05Zn0.95O) and TiO2 (Ni0.05Ti0.95O2) via immersion-assisted coprecipitation for hydrogen production. UV-Vis confirmed bandgap reduction to 2.87 eV (ZnO) and 2.82 eV (TiO2), enabling visible light activity. XRD and SEM verified Ni incorporation and a significant reduction in crystal size (to 21 nm). To mitigate rapid particle sedimentation (25 min), sodium silicate was applied as a dispersant, successfully extending suspension stability to 4 hours. Notably, this chemical stabilization maintained a lower reactor temperature (49°C) compared to mechanical stirring (52°C), preventing efficiency loss due to thermal effects. Ni0.05Zn0.95O exhibited the highest photocatalytic activity, attributed to its superior Ni atomic composition. This research demonstrates that combining Ni-doping with chemical dispersion effectively optimizes both the electronic and physical properties of photocatalysts for enhanced hydrogen harvesting.

Abstract

Household electrical installations that do not comply with safety standards remain one of the leading causes of fires due to electrical short curcuits in residential areas. Limited public knowledge of electrical installation standards and the importance of protection systems highlights the need for educational programs. This community service program aimed to improve community knowledge and awareness of fire hazard mitigation through education on standardized household electrical installations based PUIL 2011. The program was conducted on May 19, 2026, in Tegal Yoso Village and involved 20 participants. The Participatory Technology Development approach was implemented through lectures, discussions, demonstrations, hands-on practice, and evaluation using pre-test and post-test. The results showed an increase in participants’ average knowledge score from 42.1% to 92.1%. Participants demonstrated improved understanding of the functions of MCB, grounding systems, SNI-compliant electrical materials, and fire prevention measures. These findings indicate that practice-based education effectively improves community literacy on electrical safety.
