Latar belakang: Air bersih merupakan kebutuhan dasar manusia yang berperan penting dalam kesehatan dan kesejahteraan. Namun akses terhadap air bersih yang aman masih menjadi masalah di berbagai wilayah, termasuk di Kota Tanjungpinang. Banyak rumah tangga yang masih menggunakan sumur gali sebagai sumber udara, dengan kualitas udara yang tercemar, salah satunya oleh kandungan besi (Fe). Kondisi ini diperburuk oleh karakteristik tanah bauksit yang bersifat asam akibat reklamasi. Penelitian ini bertujuan untuk mengetahui pemanfaatan kombinasi arang aktif dari kulit singkong dan ampas tebu dalam menurunkan kadar besi (Fe) pada air sumur gali.Metode : Jenis penelitian ini adalah eksperimen dengan desain one group pretest-posttest , menggunakan 1 sumur gali sebagai sampel dengan kriteria berwarna kuning kecoklatan, berbaur, dan membentuk lapisan kerak kuning di sekitat sumur gali, dengan menggunakan variasi ketebalan. Data diperoleh melalui observasi secara langsung dan uji laboratorium di PT. Sucofindo (Persero) Batam, serta dijelaskan secara univariat.Hasil: Hasil penelitian menunjukkan bahwa hilangnya bau dan rasa, namun tidak dengan warna pada sampel udara setelah diberi perlakuan. Naiknya nilai pH udara dari pH asam (6,3) menjadi pH netral (6,5-8,5) setelah diberi perlakuan, dan tidak terjadinya penurunan kadar besi (Fe) pada udara.Simpulan : Penggunaan arang aktif kulit singkong dan ampas tebu efektif dalam menghilangkan bau dan rasa, serta menetralkan pH pada udara, namun tidak efektif dalam menghilangkan warna dan menurunkan kadar besi (Fe) pada udara. Peneliti selanjutnya bermaksud menambahkan media filtrasi untuk menghilangkan warna udara, menyesuaikan ketebalan adsorben, serta menggunakan metode aerasi dan waktu kontak pada saat perlakuan.

Background: The management of organic waste from restaurants in urban areas remains a significant environmental challenge because it contributes to pollution and increased greenhouse gas emissions. Bioconversion using Black Soldier Fly (BSF) larvae offers a promising solution for the rapid decomposition of organic waste while producing biomass products that have economic value. This study aims to evaluate the performance of BSF larvae with different initial weights (10 g, 20 g, and 30 g) in processing organic waste from restaurants. Methods: This experimental study with an observational approach used organic waste collected from restaurants in Tanjung Ayun Sakti Village. Five-day-old BSF larvae, which were cultivated under controlled conditions, were used in three treatment groups based on the initial weight of the larvae (10 g, 20 g, and 30 g). Larval performance was measured through waste reduction index, bioconversion rate, and feed conversion ratio. Results: The results showed that the waste reduction index for the use of 10 g, 20 g, and 30 g of larvae was 40.37%, 55.15%, and 59.27%, respectively. The bioconversion rate for the use of 10 g, 20 g, and 30 g of larvae is 2.96%, 6.67%, and 7.78%, respectively. The feed conversion rate when using 10 g, 20 g, and 30 g of larvae, respectively, was 33.75, 15.00, and 12.86. larvae biomass increased significantly with final yields of 267 g, 600 g, and 700 g. Conclusion: The results showed that the use of 30 g of larvae was the most effective compared to 10 g and 20 g of larvae based on the data waste reduction index, bioconversion rate, and feed conversion ratio. Overall, the significant increase in final larval biomass, reaching up to 700 g, confirms that higher larval quantities have a markedly positive impact on bioconversion efficiency and biomass productivity.

Clean and healthy living behaviours (PHBS) are habits practised by individuals or families that enable them to take independent action on health issues and play an active role in health initiatives both within the family and in the community. PHBS can start with oneself and one's family through clean and healthy habits in daily life. The implementation of PHBS is also an important step in preventing various diseases in children, especially diseases that are difficult to prevent, one of which is stunting. The target audience for this outreach programme was housewives in Kampung Sidomulyo RT 002/RW 13. The outreach programme was conducted through presentations and discussions. Before the outreach programme was implemented, a pre-test questionnaire was administered to determine the level of knowledge about PHBS related to stunting. Then, outreach material on household PHBS and clean water was provided. Following the presentation of the material, a discussion session and post-test were conducted to assess the level of understanding of the material provided. The results of the respondents' knowledge before the PHBS counselling (pre-test) were 5.12%, and the results of the respondents' knowledge after the PHBS counselling (post-test) were 5.94%. Socialisation of PHBS to housewives has been proven to increase their knowledge about the importance of implementing clean and healthy living behaviours in the household environment. This increased understanding plays an important role in encouraging the adoption of daily healthy habits, which not only maintain family hygiene and health, but also serve as a strategic step in preventing stunting in children. With better knowledge, housewives can play an active role as the main drivers of family and community health.

Dug well water often contains organic and inorganic components, including various dangerous metals that are commonly found in it, such as iron (Fe). Therefore, this research aimed to determine the combination of aeration and filtration methods using chitosan from gonggong shells to reduce Fe levels in dug well water in the Andana Housing Complex, Tanjungpinang City. This research implemented a pre-experimental design. Water samples were obtained from 10 dug wells in the Andana Housing Complex, Tanjungpinang City. The samples were treated with a combination of aeration and filtration methods using chitosan from gonggong shells. Before and after treatment, physical conditions of the water were observed and laboratory tests were carried out to measure Fe levels. After treatment, it was discovered that the smell, color and taste disappeared. Meanwhile, there was also a decrease in Fe levels of 80.95% for gonggong snail shell chitosan with a thickness of 1 cm, 84.93% for a thickness of 3 cm, and 98.33% for a thickness of 5 cm. It was concluded that the combination of aeration and filtration methods using chitosan from gonggong shells was effective in improving the physical conditions of water and reducing Fe levels in water. Suggestions for further research include: improving this research by adding other media to reduce Fe levels or combining it with filtering media and other methods. Suggestions for the community to process chitosan from gonggong snail shells in water treatment containing Fe and offer the government to socialize the use of chitosan filtration from gonggong snail shells. Keywords: dug well; Fe; gonggong snail shell; chitosan

The oral cavity is the most complex and easily accessible site for microbial colonization in the human body. Teeth, gingiva, tongue, and buccal mucosa have different surfaces for microbial colonization. To reduce microbes in the oral cavity, medicinal plants can be used. Medicinal plants that can be utilized include Betel Leaves and Kalamansi orange. Betel leaves are well-known in Indonesian society not only for their traditional consumption but also for their widespread availability throughout Indonesia. The study aimed to develop a new mouthwash candidate using organic materials without the addition of alcohol compounds. This research was a laboratory experimental study, involving the preparation of betel leaf extract, the production of Betel Kalamansi Mouthwash (Sirkala), and testing the Betel Kalamansi Mouthwash (Sirkala) against two types of bacteria, Streptococcus mutans and Bacillus cereus, compared to the patented Listerine mouthwash. The stages include organoleptic testing and data processing. The expected outcome of this research is the development of an alcohol-free mouthwash made from organic materials. Microbiological effectiveness test results show that the herbal mouthwash formula Sirkala can effectively eliminate the target bacteria Streptococcus mutans, with a killing ability of up to 99.999% at contact times of 10, 15, and 20 seconds. This is comparable to the results of testing Listerine mouthwash widely available in the market. However, based on testing against Bacillus cereus, the herbal mouthwash formulation Sirkala is unable to eliminate the target bacteria like Listerine mouthwash.
