Abstract

Danau Perupuk merupakan danau oxbow yang menerima air dari Sungai Kampar pada saat banjir. Ketika air sungai meningkat dan mengalir ke dalam danau, banyak jenis ikan yang masuk ke danau dan kelimpahan serta jenis ikan yang ada di danau pun meningkat. Penelitian ini bertujuan untuk mengetahui jenis-jenis ikan di Danau Perupuk, telah dilakukan penelitian pada bulan September hingga Oktober 2023. Pengambilan sampel dilakukan sebanyak 6 kali, yaitu 3 kali pada saat banjir dan 3 kali pada saat tidak ada hujan. Ikan-ikan tersebut ditangkap dengan menggunakan jaring insang dan bubu. Sampel ikan yang tertangkap kemudian diidentifikasi. Hasil penelitian menunjukkan bahwa ikan yang tertangkap terdiri dari 6 ordo, 11 famili, 23 genus dan 26 spesies. Jumlah jenis ikan yang tertangkap lebih banyak pada saat banjir dan lebih sedikit pada saat tidak ada banjir, masing-masing sebanyak 22 dan 15 jenis. Di antara 26 jenis ikan yang tertangkap, terdapat 1 jenis ikan hias, 10 jenis ikan konsumsi, 15 jenis ikan hias-konsumsi dan 1 jenis ikan yang dilindungi. Kualitas air danau adalah sebagai berikut: suhu 28-30ºC, kecerahan 40-52,5 cm, kedalaman 0,5-6,2 m, pH 6, oksigen terlarut 4,2-5,6 mg/L dan karbondioksida bebas 5,99-8,19 mg/L

Abstract

The growth rate and mortality rate of giant prawns (Macrobrachium rosenbergii) in the Kuala Cenaku River, Indragiri Hulu Regency, Riau Province were carried out based on carapace length frequency data collected from May to July 2020. This study aims at the growth rate and mortality of giant prawns in the Kuala Cenaku River. For estimating dynamic population, data were analysed by using FiSAT II. The growth parameter of tiger shrimp was 0,78/year with carapace asymptotic length (L ) of 84,8 mm, total mortality rate (Z), natural mortality rate (M), fishing mortality rate (F) were 2,35/year and 1,16/year, 1,19/year, respectively, while and exploitation rate (E) estimated 0,50. The exploitation rate of Tiger Freshwater Prawn in Kuala Cenaku River was fully exploited and tend to overexploited so that it needed to manage wisely and carefully

Abstract

Narrow barred Spanish mackerel and wolf herring is an important commodity that has commercialized intensively to fulfill the needs of the market, both domestic and export. Research has been conducted from June-August 2020 in Malacca Strait Waters. The purpose of this study is to analyze the dynamics of population parameters such as growth rate, mortality rate, exploitation rates, and recruitment patterns of narrow barred mackerel (Scomberomorus commerson) and wolf herring (Chirocentrus dorab). The Sample size of spanish mackerel was taken at randomly from the purse seiner and gillnet catches. Data of size obtained were used for the analysis of population dynamics parameters. Some population dynamics parameters were estimated using the program FISAT II. Von Bertalanffy growth parameters of spanish mackerel were derived L and growth rate (K),for males 772.8 mm and 0.5/year and for females 979.65 mm and 1,7/year and wolf herring was derived L and growth rate (K), for males 871.5 mm and 0.59/year, and for females 1048.95 mm and 0.65/year, respectively. Total mortality (Z) of spanish mackerel males and females was 0.61/year and 4.07/year and the wolf herring males and females was 0.36/year and 1,3/year. Fishing mortality rate of spanish mackerel (F) for males and females was 0,13/year and 3.07/year high than natural mortality rate (M) 0.48/year and 1/year and wolf herring fishing mortality rate for males and females was 0.16/year and 0.78/year lower than natural mortality rate (M) 0.52/year. Exploitation rate (E) of spanish mackerel for males and females was 0.21/year and 0.75/year and wolf herring for males and females was 0.44/ year and 0,6/year, that almost full exploitation when compared with optimum of 0.40. The recruitment pattern of Spanish mackerel for males was (14.59%) in June and for females was (26.84%) in August and wolf herring for males was (16.02) in June, and for females was (28.63%) in July.

Abstract

The purpose of this study is to know the value of an economic benefit of the total mangrove forest located in the village of Pulau Cawan Indragiri Hilir regency, namely using the concept of valuation economic in calculating the benefits of mangrove existence that has the potential of existing natural resources. This research was conducted in August 2020, The observations made in the field use observations and direct interviews with the local government and the community around the village of Pulau Cawan. The results of the research obtained showed the ecosystem of the mangrove forest area of the village of Pulau Cawan which has an area of ±3,401.66 ha, and there is a value of existing benefits of IDR 21.200.000 ha/year. The factors that will affect the willingness to pay (WTP) of the community around mangrove forests in the form of the respondent's income level, the respondent's education level, the respondent's gender, the respondent's age and the respondent's family dependents. The benefit value of the existence of The Village of Pulau Cawan can be used as a basis for decision-making by the local government and the surrounding community in the management of policies and utilization of mangrove forests in maintaining and preserving mangrove forest ecosystems for the sustainability of the future. With the results obtained in knowing the existence of the value function of a mangrove ecosystem, it can result in the formulation of the mangrove forest conservation reserve area of Pulau Cawan village, namely the implementation and development of the “Ecu-Edu Wisata Mangrove” (EEWM) concept plan.

Abstract

The objectives of this study were to analyze mangrove community structure, estimate carbon storage and CO₂ sequestration potential, assess the economic value of CO₂ sequestration, and formulate management strategies for mangrove forests in the coastal area of Bangko Subdistrict, Rokan Hilir Regency. This research was conducted in October 2024 in the coastal area of Bangko Subdistrict, Rokan Hilir Regency, Riau Province. The method applied was a survey-based approach. Sampling stations were determined using purposive sampling. Mangrove community structure data were collected using 10 m × 10 m quadrat transect plots. A total of six observation stations were established, with three plots per transect. The potential carbon stock of the mangrove ecosystem was calculated based on carbon content from trunk biomass, roots, litter, and sediment. Biomass carbon estimation utilized species-specific allometric equations. The results recorded seven mangrove species: Avicennia alba, A. eucalyptifolia, A. lanata, Bruguiera parviflora, Rhizophora apiculata, R. mucronata, and Sonneratia alba. The highest relative density and the highest relative frequency were recorded for A.alba at Station I (75%) and Station II (42.86%). The highest relative dominance was recorded for Sonneratia alba at Station V (52.05%). The highest Importance Value Index (IVI) was observed for Avicennia alba at Station I (151.15%). The mangrove ecosystem in the coastal area of Bangko Subdistrict has an average carbon stock potential of 382.37 tons/ha, with an estimated CO₂ sequestration potential of 1,277.21 tons per hectare, totalling 15,893,618.87 tons. The estimated average economic value of carbon sequestration is IDR 1,081,274,726/ha, equivalent to IDR 13,455,438,919,367. Sustainable mangrove ecosystem management as a contribution to climate change mitigation can be implemented through the following strategies: ecosystem rehabilitation and protection, strengthening governance and law enforcement, community empowerment and alternative livelihood development, increased awareness and cross-sectoral coordination, and continuous monitoring and research
