Abstract

As population activity is increasing and the Kapuas river is still a means of transportation, causing Corbicula largillierti to accumulate heavy metals (Pb) and Coliform bacteria in their bodies. This makes it dangerous to be consumed by humans. Thus, this research has two main aims. First, to find out the concentration of Pb and Coliform inside Corbicula largillierti that lives at Kapuas river, Pontianak and the river’s water. Second, to analyze the health risk of consuming the clams. Furthermore, the Atomic Absorption Spectrophotometer (AAS) is used to analyze the Pb sample and the Most Probable Number (MPN) method is used to analyze the Coliform. The result of this research shows that concentration Pb and Coliform from the Kapuas river have exceeded the limits designated for aquatic biota based on the Decree of the State Minister for the Environment No. 51 of 2004. In addition, the health risk is measured using Estimated Daily Intake (EDI), Target Hazard Quotient (THQ) and Target Carcinogenic Risk (TR) with scores for each are >10 times the RfD, >1 and 10−3. This result shows that based on the clam Corbicula largillierti consumption for 70 years life span of 60 kg body weight,  had a high and negative effect on health risk problems and had a cancer risk for consumers. However, the health risk problem might increase much worse due to the long and continual period of consumption exceeding estimated daily intake.

Abstract

One of the coral reef ecosystems in West Kalimantan is located on Pelapis Island, North Kayong Regency. Coral reefs are coastal ecosystems with a high level of diversity but are vulnerable to various local and regional disturbances. Coral reef ecosystems are also a natural habitat for several types of marine biota. Coral reefs also play a role in coastal protection and provide services for tourism. The function of the coral reef ecosystem is highly dependent on the condition of the ecosystem. Therefore, research on the condition of coral reefs is substantial to study. Observations of coral reef ecosystems on Pelapis Island were carried out using Scuba at a depth of 5-7 m. Coral reef data collection was carried out using the Line Intercept Transect (LIT) method. Data on water conditions were obtained in situ and through analysis in the laboratory. The results showed that the waters on Pelapis Island were suitable for the growth of coral reefs. According to Minister of Environment Decree No. 4 of 2001, the coral reef ecosystem at station 2 was included in the good category and moderately damaged category at station 1 with a percentage of coral cover of 62.82% and 42.13%, respectively. Hard corals at both locations were dominated by massive coral (CM). The data obtained can be one of the references in regional management and sustainable use of marine space

Abstract

Kelimpahan fitoplankton dapat dipengaruhi oleh nitrat dan fosfat. Nitrat berperan dalam proses sintesis protein dalam pertumbuhan fitoplankton dan fosfat berperan dalam proses pertumbuhan dan metabolisme fitoplankton. Penelitian ini bertujuan untuk melihat pengaruh nitrat dan fosfat terhadap kelimpahan fitoplankton. Penelitian dilakukan dibulan Agustus 2022. Pengambilan sampel dilakukan di 3 titik lokasi penelitian yaitu di area dekat mangrove (pengambilan sampel di sungai dan kanal di dalam hutan mangrove), area dekat pasar ikan dan area jauh dari laut. Sampel yang diambil yaitu sampel air sebanyak 100 ml untuk analisis fitoplankton. Hasil penelitian menunjukkan konsentrasi nitrat dan fosfat yaitu 0,4 – 3,6 mg/l dan 0,94 – 6,3 mg/l. Konsentrasi nitrat tertinggi terdapat di area sungai sedangkan kandungan fosfat terbanyak terdapat di Stasiun 3 yang jauh dari laut. Kelimpahan fitoplankton tertinggi di Stasiun 2 yang terletak di Pasar Ikan dengan kelimpahan fitoplankton 832 ind/l, keanekaragaman (0,31 - 1,84), keragaman (0,17 – 0,95), dominansi (0,22 – 0,86). Hasil identifikasi yang telah dilakukan, fitoplankton yang terdapat di Perairan Sungai Bakau Besar terdiri dari 23 genera dan didominasi oleh Skeletonema sp. Dari hasil penelitian menunjukkan bahwa pengaruh nitrat dan fosfat terhadap kelimpahan fitoplankton pada penelitian ini tergolong sangat rendah yang mana terdapat faktor lain dalam mempengaruhi kelimpahan plankton.

Abstract

The positive impact of chitosan has been widespread and has attracted interest from farmers with the pretext that it is safe for the environment. However, information on the adverse effects of using chitosan on plants still needs to be available. This study aims to discover the side effects of applying chitosan on the Brassica juncea. This test is done using Complete Random Design (CRD). The test is carried out by applying a solution of chitosan with five series of concentrations (0.5%, 1.5%, 2.5%, 3.5%, and 4.5%) plus control of acetic acid 1% (AA) to the upper and lower surfaces of the B. juncea leaves (old and young leaves) using a brush smooth to drip wet. The trial was repeated four times. Data was analyzed using ANOVA (Analisis of Variance). When there is a significant difference between the treatments, further tests are conducted using DMRT at a substantial level of 5%. In two week and three week B. juncea plant, the highest chlorophyll content is observed in the chitosan with a concentration of 3.5% and 0.5% with the same value of 0.74 mg/g, while the lowest concentration is at 1.5% 0.61 mg/g at the age of two weeks and 0.50 mg/g at three weeks. Using chitosan at high concentrations (2.5-4.5%) indicates phytotoxic occurrence in the leaves of two week or three week old B. juncea plants. Phytoxic indications are seen in rolling leaves, thickening, and structurally more hardinge when compared with low concentration (0.5% and 1.5%) and control treatments. It is best to pay attention to the use of concentrations of chitosan so that plants get optimal positive effects without causing adverse side effects.

Abstract

The priority issues at Sungai Bakau Besar Laut (SBBL) village are about how to preserve the mangrove ecosystem in line with improving the community's economy. This is also the basis for the consideration of the PKMS Faperta UNU Kalimantan Barat in designing a mangrove ecosystem management program so that the area can have a tourist attraction, be more productive from a cultivation perspective and maintain its sustainability to support the community's economy. The aim of implementing this PKMS is as a stimulus for the people in SBBL village to play an active role in the conservation of mangrove ecosystems. In fact, it is hoped that through the AgroEduTourism design provided, it will be able to improve community welfare and contribute to accelerating mangrove rehabilitation to the surrounding area. Several solutions are offered to overcome the problems faced by partners, namely: 1) organizing training on integrated fisheries agribusiness management based on agrosilvofisheries, 2) Providing stimulus to aquaculture businesses in the form of providing fish seeds and providing starter feed. 3) Organize mangrove planting as a rehabilitation measure for degraded mangrove areas; 4) Redesigning tourist areas to make them more attractive and representative for the purpose of educational agro-tourism. The results of the PKMS carried out were the training of 15 SBBL residents to cultivate fish in an integrated manner. Provided assistance of 7500 fish breeds and feed to the training participants. The design of an agro-tourism area has been produced which has four functions, namely tourism, cultivation, education and conservation

Abstract

Air gambut memiliki pH rendah, kandungan logam berat yang tinggi, TSS dan TDS yang tinggi sehingga memerlukan pengolahan sebelum digunakan sebagai sumber air untuk budidaya perikanan. Tujuan penelitian ini untuk mengetahui pengaruh cangkang telur, Ca-alginat, dan Ca-alginat cangkang telur terhadap pH, TSS, serta TDS air gambut. Cangkang telur ayam diketahui mengandung CaCO3 yang bisa digunakan untuk pengolahan air gambut. Namun, penggunaan serbuk cangkang telur memiliki keterbatasan dalam memisahkan adsorben dan adsorbatnya jika digunakan sebagai adsorben. Enkapsulasi cangkang telur menggunakan Ca-alginat dapat mengatasi keterbatasan tersebut. Metode penelitian ini menggunakan metode adsorpsi. Hasil penelitian menunjukkan peningkatan pH air gambut dari 4,3 menjadi 6,5, 6,7, dan 6,6 masing-masing untuk adsorben cangkang telur, Ca-alginat, dan Ca-alginat cangkang telur. TSS pada air gambut juga mengalami peningkatan dari 20,5 mg/L menjadi 39 mg/L, 34,5 mg/L, dan 32 mg/L masing-masing untuk adsorben cangkang telur, Ca-alginat, dan Ca-alginat cangkang telur. Peningkatan juga terjadi pada TDS air gambut dari 36,5 mg/L menjadi 94 mg/L, 45 mg/L, dan 42 mg/L masing-masing untuk adsorben cangkang telur, Ca-alginat, dan Ca-alginat cangkang telur. Penggunaan adsorben Ca-alginat cangkang telur meningkatkan nilai pH, TSS, dan TDS air gambut yang masih sesuai dengan baku mutu air kelas tiga berdasarkan PP RI Nomor 22 Tahun 2021.

Abstract

The priority problem that needs to be overcome in Sungai Deras Village by the PKM team is to restore vegetation lost by land clearing activities in order to maintain the protection function of the area. The availability of nectar from flowering vegetation as a source of feed for kelulut bees cultivated by residents is still limited, the availability of sufficient feed will affect the volume and quality of honey produced. The knowledge of community members related to the technology and management of kelulut honey cultivation is still relatively low. In addition, the tourist area in Sungai Deras village needs the addition of better attractions and promotions so that it is increasingly known and in demand by the wider community in West Kalimantan and at the national level. The purpose of this community empowerment activity is expected that honey bee cultivation can also be of tourist attraction value by making the land around existing tourist sites into kelulut cultivation land. This business is not only economic, ecologically also has educational value because it can be used as a location for practice and research for students, lecturers and the general public who want to learn about forest ecosystems and kelulut bee cultivation while traveling (Ecoedutourism). The solution offered by the PKM team is to organize and plant to enrich the number and type of vegetation feed for kelulut bees using an integrated cultivation pattern between forestry, bees and fisheries in one location (SIlvoapifisheries) which also has ecotourism and educational values. PKM activities consist of technical guidance on kelulut cultivation, installing 20 kelulut colonies in stup which will be further developed communally, revegetating the land around kelulut cultivation with types of fruit, flower and medicinal plants. It is hoped that the enrichment of vegetation and cultivating kelulut can maintain the function of protection control and increase community income from the tourism sector.
