Abstract

This Lake Sentani in Papua Province has significant ecological and economic value and is a source of life for the local community. However, intensive anthropogenic activities around the lake result in a decline in water quality that threatens the ecosystem and public health. This study aims to examine the water quality status of Lake Sentani using the British Columbia Water Quality Index (BC-WQI) method, which is able to integrate various physical, chemical, and biological parameters into one quality index that is easy to interpret. Data collection was carried out at three location points in the upstream, middle, and downstream parts of Lake Sentani, with in situ and ex situ testing for ten water quality parameters such as TDS, pH, BOD, COD, heavy metals Pb, oils and fats, and total coliforms. The calculation of the water quality index uses the values of F1 (scope), F2 (frequency), and F3 (amplitude) to determine the BC-WQI. The results showed that at station 1 (Ifale) the BC-WQI value was 37.62 (good quality), at station 2 (Asei) it was 49.92 (poor quality), and at station 3 (Jaifuri) it was 67.69 (poor quality). Thus, the water quality downstream of the lake is classified as unsafe for consumption or clean water without adequate treatment. This study shows the importance of integrated management and efforts to preserve water quality to maintain the sustainability of Lake Sentani.

Abstract

ABSTRAK Memanfaatkan air yang higiene sanitasi mutlak diperlukan agar terhindar dari dampak negatif yang tidak diinginkan. Penelitian ini dilaksanakan dengan mengambil empat titik sampel (stasiun) air sumur gali di Kampung Yamta Arso Kabupaten Keerom Papua pada bulan Agustus sampai Oktober 2022. Penelitian ini bertujuan untuk mengetahui status mutu air dengan metode indeks pencemaran. Parameter pencemaran air yakni: parameter fisika (kekeruhan, warna, TDS dan suhu, rasa dan bau), parameter kimia (pH, besi, flourida, kesadahan, mangan, nitrat, nitrit, sianida, detergen dan pestisida total) serta parameter biologi (coliform total dan Escherichia coli). Hasil penelitian menunjukkan bahwa status mutu air sumur gali pada stasiun 2 dan 3 diperoleh indeks pencemaran berturut-turut sebesar 2,00 dan 2,67 tergolong tercemar ringan, sedangkan pada stasiun 1 dan 4 diperoleh indeks pencemaran berturut-turut sebesar 0,65 dan 0,69 termasuk kategori baik (memenuhi baku mutu). Parameter yang tidak memenuhi baku mutu air adalah kekeruhan, pH, besi, detergen dan Escherichia coli. Hal ini dikarenakan melebihi baku mutu. Rancangan pengendalian air yang cocok agar memenuhi persyaratan baku mutu perlu dilakukan filtrasi dengan media zeolite, pasir, ijuk dan karbon aktif (karang tempurung kelapa) dan menambahkan sedikit klorin (kaporit) dan atau tawas pada bak penampung sebelum filtrasi. Kata kunci: Mutu, Air, indeks, Sumur, Yamta.  ABSTRACT Utilizing water that is hygienic and sanitary is absolutely necessary to avoid unwanted negative impacts. This research was carried out by taking four sample points (stations) of dug well water in Yamta Village, Arso District, Keerom Regency, Papua from August to October 2022. The aim of this research was to determine the status of water quality using the pollution index method. The Water pollution parameters were: physical parameters (turbidity, color, TDS and temperature, taste and smell), chemical parameters (pH, iron, fluoride, hardness, manganese, nitrate, nitrite, cyanide, detergent and total pesticides) and biological parameters (coliform total and Escherichia coli). The results of the research showed that the water quality status of dug wells at stations 2 and 3 obtained a pollution index of 2.00 and 2.67, respectively, which was classified as lightly polluted, while at stations 1 and 4, pollution indices were obtained, respectively, of 0.65 and 0.69 was included in the good category (met the quality standards). Parameters that did not meet water quality standard were turbidity, pH, iron, detergent and Escherichia coli. This is because it exceeded the quality standards.  A suitable water control design to meet quality standard requirements requires filtration using zeolite, sand, palm fiber, and activated carbon (coconut shell coral) media and adding a little chlorine (chlorine) and/or alum to the holding tank before filtration. Keywords: Quality, Water, Index, Well, Yamta

Abstract

Lake coastal communities utilize Lake Sentani's water to meet clean and other needs such as industry, irrigation, plantations, fisheries, and water transportation facilities. In addition to the lake mentioned above, they use it as a garbage dump and family waste; even human and animal feces are thrown into Lake Sentani. This study aims to determine the quality and quality status using the STORET method based on PP 22 of 2021 concerning the Implementation, Protection, and Management of the Environment annex vi-2 class 1 by applying ten parameters. The study used three stations: Ifale, Asei, and Jaifuri coast. Each station was sampled four times: January, April, July, and October 2023. The results showed that seven parameters did not meet the quality standards, namely TSS, BOD, COD, Pb, Oil and Fat, Total Ditergen, and Total coliform, and only three parameters met the quality shoulder, namely temperature, TDS, and pH. Water quality status based on the application of the STORET method was obtained that station 1 obtained a score of -26 based on US_EPA, including class C (moderately polluted), station 2 obtained a score of -64, including class D (heavily polluted), and station 3 obtained a score of -116 including class D (heavily polluted) and the average STORET score of the three stations was obtained -68.67 including class D (heavily polluted).

Abstract

Information on fruit flies is essential for integrated fruit fly control programs, whilst such information remains very limited in Papua. This study aims to determine the species diversity and abundance of fruit flies in agroecosystems (Yuwanain) and secondary forest ecosystems (Ubiyau) in Arso District, Keerom Regency. Sampling locations were determined using purposive sampling. Fruit fly samples were collected using plastic bottle traps baited with methyl eugenol. Observations were conducted during May and June 2025. Four species of fruit flies were found in Arso District: Bactrocera musae, B. umbrosa, B. fulvicauda, and B. dorsalis complex. All four species were found in the agroecosystem area in Yuwanain, whilst in the secondary forest in Ubiyau, only three species were found: B. musae, B. umbrosa, and B. fulvicauda. All species were pests except B. fulvicauda. The Shannon-Wiener species diversity index values for fruit flies in the agroecosystem (H’ = 0.7) and in the secondary forest (H’ = 0.4) were both categorized as low. The Simpson Dominance Index in Yuwanain was classified as moderate (D = 0.636), whilst in Ubiyau it was categorized as high (D = 0.800). In Yuwanain, B. musae was highly dominant (D = 0.617) with a total individual count of 3,080. The dominance of B. musae in Yuwanain was attributed to the abundance of its primary host plant, banana, in the agroecosystem. The evenness index in Yuwanain village was moderate (E = 0.521), whereas in Ubiyau it was low (E = 0.381), indicating that the distribution of individual numbers for each species was uneven in the Secondary Forest. Fruit fly abundance was higher in the agroecosystem of Yuwanain (3,921 individuals) than in the secondary forest of Ubiyau (2,272 individuals). This difference is likely due to the greater diversity of host plants in the Yuwanain agroecosystem, including banana, papaya, jackfruit, citrus, wax apple, breadfruit, and chili. In contrast, the secondary forest of Ubiyau contains fewer naturally occurring host plants, such as the native Papua banana and breadfruit. It can be concluded that the species composition and abundance of fruit flies at certain habitat types were determined by the diversity and abundance of host plants.

Abstract

Access to clean water is still a crucial problem in Hobong Village, Sentani District, Jayapura, which has an impact on the high number of water-related diseases. Initial observations show that 78% of people in this area still use Lake Sentani water without adequate treatment, even though studies show that the quality of the lake water has decreased due to pollution. This community service program aims to improve community knowledge and skills in clean water treatment through a simple filtration system. The methods used include community education in the form of socialization of the importance of clean water, diffusion of science and technology through the creation of filtration system prototypes, training in filter creation and maintenance, mediation between stakeholders, and advocacy for clean water policies. The results of the program showed an increase in community knowledge of up to 100%, with the highest increase in the aspect of filtration system maintenance (182.1%). The filtration system developed effectively reduced E. coli (97.9%), Total Coliform (93.3%), turbidity (84.4%), and color (82.9%). This program also succeeded in forming a Clean Water Care Community Group, encouraging the ratification of Village Regulations on Clean Water Management, and obtaining village fund allocations for the development of filtration systems. A 61.7% reduction in diarrhea cases in the 3-month post-program period proves that a comprehensive approach to providing clean water can have a significant impact on public health in remote areas.

Abstract

Fruit flies are the main pests causing decreased productivity of horticultural crops in Walma Village, Skanto District, Keerom Regency. This pest attack causes significant economic losses for local farmers with fruit damage rates reaching 40-60%. This community service activity aims to increase farmers' knowledge and skills in utilizing methyl eugenol pheromones as environmentally friendly biopesticides to control fruit flies. Implementation methods include counseling on fruit fly biology and pheromone mechanisms, training on making pheromone traps using local materials, demonstration of trap installation in fields, and continuous assistance during three months of planting season. This activity involved 35 farmers from Walma Village who own horticultural land. The results showed an increase in farmers' knowledge by 78% from pre-test to post-test, successful installation of 140 pheromone trap units in 15 hectares of land, reduction in fruit fly attack rates from 45% to 18%, and increase in harvest yields by 35-42%. Farmers also showed high enthusiasm with commitment to continue using this biopesticide. This activity makes a real contribution to increasing sustainable agricultural productivity and reducing chemical pesticide use in Papua region, specifically Keerom Regency.

Abstract

Kampung Hobong merupakan permukiman terapung di Danau Sentani, Distrik Sentani, Kabupaten Jayapura, yang menghadapi tantangan sanitasi karena pembuangan limbah domestik dilakukan langsung ke badan air. Penelitian ini bertujuan mengidentifikasi kondisi eksisting sanitasi lingkungan, menganalisis pengaruhnya terhadap kualitas air Danau Sentani, serta merumuskan strategi pengelolaan sanitasi yang berkelanjutan. Penelitian menggunakan pendekatan mixed method dengan 48 responden di RW 1 Kampung Hobong yang dipilih secara purposive, dilengkapi uji laboratorium kualitas air pada tiga stasiun. Hasil menunjukkan bahwa skor perilaku hidup bersih dan sehat (PHBS) dan pengetahuan sanitasi masyarakat tergolong baik (masing-masing 84,4% dan 78,8% dari skor maksimal), namun hasil uji laboratorium menunjukkan parameter bakteriologis (E. coli dan total coliform) serta indikator pencemaran organik (BOD, COD, DO, amonium) melampaui baku mutu Permenkes No. 32 Tahun 2017 di seluruh stasiun. Uji korelasi Pearson menunjukkan peran pemerintah dan lembaga terkait memperoleh skor terendah (64,7%) dan berkorelasi kuat dengan partisipasi masyarakat (r = 0,803; p < 0,001), sehingga lemahnya dukungan kelembagaan menjadi faktor penghambat utama sanitasi berkelanjutan. Analisis SWOT dan kerangka Sanitation Safety Planning menghasilkan empat arah strategi: teknis, kelembagaan, pembiayaan, dan pemberdayaan masyarakat. Penelitian ini merekomendasikan penguatan infrastruktur dan kelembagaan sanitasi sebagai prioritas utama tanpa mengabaikan modal perilaku dan partisipasi sosial masyarakat Kampung Hobong.

Abstract

Danau Sentani merupakan danau terbesar di Provinsi Papua yang memiliki fungsi ekologis dan sosial-ekonomi penting bagi masyarakat di sekitarnya. Namun, peningkatan aktivitas antropogenik berupa limbah domestik, pertanian, dan keramba jaring apung (KJA) telah menjadi ancaman terhadap kualitas airnya. Penelitian ini bertujuan untuk: (1) menganalisis kondisi kualitas air Danau Sentani berdasarkan parameter fisika dan kimia; (2) menentukan status mutu air menggunakan metode Weighted Arithmetic Water Quality Index (WAWQI); dan (3) mengidentifikasi parameter yang paling berpengaruh terhadap penurunan kualitas air. Pengambilan sampel air dilakukan pada lima titik lokasi, yaitu Kampung Ifale, Yobeh, Asei Besar, Asei Kecil, dan Jaifuri, dengan sepuluh parameter uji meliputi suhu, pH, kekeruhan, DO, TDS, BOD, COD, nitrat, fosfat, dan amonia. Analisis data menggunakan metode WAWQI mengacu pada baku mutu air kelas II Peraturan Pemerintah Nomor 22 Tahun 2021. Hasil penelitian menunjukkan bahwa parameter BOD (4,11–8,31 mg/L), COD (77–154 mg/L), dan amonia (0,35–0,42 mg/L) telah melampaui baku mutu pada seluruh lokasi. Nilai WAWQI berkisar antara 113,89 (Jaifuri) hingga 128,38 (Ifale), yang mengklasifikasikan seluruh lokasi dalam status mutu “tidak layak minum” (unsuitable for drinking). Parameter amonia, fosfat, dan BOD secara kumulatif menyumbang lebih dari 96% terhadap nilai WAWQI, dengan amonia sebagai kontributor terbesar (81,58–97,89). Penelitian ini menyimpulkan bahwa kualitas air Danau Sentani telah mengalami penurunan signifikan akibat pencemaran limbah domestik dan aktivitas keramba jaring apung, sehingga diperlukan upaya pengendalian pencemaran yang terfokus pada pengelolaan limbah domestik dan pengaturan aktivitas perikanan budidaya.
