Abstract

Ketersediaan air bersih yang aman sangat penting untuk menjaga kesehatan dan keselamatan siswa di lingkungan sekolah. TK IT Gemilang Yayasan Al Basri sebelumnya bergantung pada air galon isi ulang tanpa sistem pengolahan mandiri. Melalui kegiatan pengabdian masyarakat ini, dipasang teknologi Hydro Pure Pro (HPP) berbasis slow sand filter dan biomassa filter yang terbukti efektif dan aman. Teknologi HPP ini berbeda dari sistem filtrasi biasa karena menggabungkan pasir lambat, biomassa, dan membran 0,1 mikron dalam satu alat yang ringkas dan mudah dirawat oleh pihak sekolah tanpa bantuan teknisi. Instalasi dilakukan pada 11 Agustus 2025, mencakup satu unit alat HPP dan dua cadangan filter RO 0,1 mikron. Hasil evaluasi menunjukkan peningkatan signifikan kualitas air, dengan kejernihan lebih baik serta penurunan kadar Fe dan TDS. Berdasarkan wawancara dengan delapan responden (guru, staf, dan pengurus yayasan), diperoleh tingkat kepuasan rata-rata 93,2%, dengan nilai tertinggi pada kejernihan air (95%), penghematan biaya (93%), dan kemudahan perawatan (88%). Program ini juga memberikan kontribusi melalui pendampingan langsung berbasis sekolah, sehingga guru dan staf mampu mengelola sistem secara mandiri dan berkelanjutan. Kegiatan ini tidak hanya menyelesaikan masalah air bersih, tetapi juga menumbuhkan kesadaran dan kemandirian sekolah dalam pengelolaan air berkelanjutan, sekaligus mendukung kesehatan dan keselamatan siswa secara nyata. Installation of Hydro Pure Pro (HPP) Water Filtration Technology Using Slow Sand and Biomass Filters to Improve Student Health and Safety at TK IT Gemilang, Al Basri Foundation  Abstract Safe and clean water availability is essential to protect student health and safety in school environments. TK IT Gemilang, under the Al Basri Foundation, previously relied on refillable bottled water without an independent treatment system. Through this community service program, a Hydro Pure Pro (HPP) system based on slow sand filtration and biomass media was installed to provide an effective and safe water treatment solution. This HPP technology differs from conventional filtration systems by combining slow sand, biomass, and a 0.1-micron membrane in one compact unit that can be easily maintained by school staff without technical assistance. The installation was carried out on 11 August 2025, consisting of one HPP unit and two spare RO 0.1-micron filters. Evaluation results showed a significant improvement in water quality, with clearer appearance and reduced iron (Fe) and TDS levels. Based on interviews with eight respondents (teachers, staff, and foundation administrators), the average satisfaction level reached 93.2%, with the highest scores in water clarity (95%), cost savings (93%), and ease of maintenance (88%). This program also contributes to capacity-building through a school-based mentoring approach, enabling teachers and staff to independently operate and manage the system sustainably. Overall, this initiative not only solves the clean water problem but also fosters awareness and self-reliance in sustainable water management, supporting student health and safety in a tangible manner.

Abstract

This study examines student performance in project-based learning by assessing their tendencies toward divergent or convergent thinking. A questionnaire was developed to help teachers identify and maximize the thinking potential of individual students during the learning process. The research involved 149 junior high school students from West Lombok for validity and reliability testing and 84 respondents for the categorization trial. Instruments were validated by experts using descriptive methods and percentage scores. Validity was determined through product moment correlation coefficients, while reliability was assessed using alpha reliability coefficients. Categorization utilized non-level (nominal) categorization methods. The study employed a pre-experimental approach with a one-shot case study design, involving 33 eighth-grade students in a local natural pesticide project. Student performance was evaluated through practical skill assessments and comprehensive portfolios. Data analysis used percentage and comparative statistical methods. Results showed the questionnaire contained 40 items—20 each for divergent and convergent thinking—with an expert validation score of 89.50, rated excellent. All items were valid, with correlation values exceeding the critical threshold (rtable = 0.16). Reliability scores were high for divergent and convergent groups (0.64 and 0.72) and satisfactory for all items (0.55). The questionnaire effectively categorized up to 20% of subjects into divergent and convergent groups. The study revealed significant performance differences between the two groups and recommends mixing students with divergent and convergent propensity in group projects to enhance outcomes.
