Abstract

Industrial development and population growth cause a lot of waste to enter water bodies, causing pollution. A number of studies have been carried out to remove metal ions and dyes in waters. Adsorption is the most widely used method to absorb heavy metal ions and harmful dyes by utilizing natural resources that are still abundant, for example, agricultural, livestock, and fishery waste. Adsorption can also use activated or modified absorbent materials to increase porosity and expand the surface plane. In this review, the adsorption method and results obtained by the researcher with various absorbent materials are summarized which are mostly carried out in the last ten years. The purpose of this review is to provide input in finding alternatives to other absorbent materials or eliminating pollutants harmful to human health and the environment.

Abstract

Microplastics are plastic flakes or crumbs with a size smaller than 5 millimeters that come from large plastic fragments such as crackle bags, clear plastic, clothing waste, plastic bottles, styrofoam and sachets that are fragmented due to water currents and sun exposure. The danger of microplastics when they enter water, can absorb heavy metals and pollutants in the water, such as Chlorine, Phosphate, Manganese, and Chromium. As a result, the water ecosystem will be disrupted. If microplastics are ingested by fish, the fish's reproductive and growth systems are damaged. Moreover, it can interfere with human hormones if you consume the fish. The test was carried out using the Microplastic Rapid Test method using a stereo microscope connected to a monitor, so that with a magnification of 100 to 400 times, it can physically detect microplastics in the water. This researcher is a literature review. The database used in the search for this article uses Google Scholar and ScienceDirect with the keywords "microplastic, plastic waste effect, coastal microplastic, microplastic marine fish, microplastic and health effect", which has been carried out by previous researchers both from within and outside the country. The articles obtained were selected according to the topic of microplastic pollution in coastal areas, which can be downloaded, and articles published from 2018-2024. The articles reviewed were 10 articles that were relevant and according to the topic.

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.
