PENILAIAN EKONOMI JASA PENYEDIAAN EKOSISTEM WADUK KOTO PANJANG KABUPATEN KAMPAR RIAU

This research was conducted during start in January 2015 - July 2015. It’s was aimed to generate economic value of ecosystem services Koto Panjang Reservoir by calculating the total economic value of ecosystems Koto Panjang Reservoir. The method used is survey by using primary and secondary data. The analytical method used to calculate the total economic value of ecosystems Koto Panjang Reservoir using total economic value framework and the framework of the millennium ecosystem assessment. Based on the research of the study obtained the economic value of ecosystem Koto Panjang Reservoir obtained successively for cultivation activities amounting are Rp. 334 233 226, capture fisheries activities of fishing boat engines Rp. 1264469391, capture fisheries activities of fishing rowboats Rp. 232 924 194 the total economic value of Rp. 1831626811.

Morphometric Characteristics of Asian Catfish, Hemibagrus wyckii (Bleeker, 1858) (Bagridae), from the Riau Province of Indonesia.

Asian Catfish (Hemibagrus wyckii) is an important fish having both food and a high price in the market. These species are categorized as a carnivorous freshwater finfish native in Indonesia and is vulnerable to endangered status. This study was carried out to identify the morphometric characteristics of Hemibagrus wyckii (H. wyckii) from the Koto Panjang Reservoir, Kampar Kanan and Kampar Kiri rivers. Twenty-five fish were collected from each sampling site. The morphometric characteristics were analyzed using the truss morphometric method. Twenty-nine characteristics were measured to obtain the morphometric characteristics of this species. Morphometric data of H. wyckii were analyzed using one-way ANOVA (SPSS version 17.0). Principal component analysis (PCA) was used to evaluate the relationship between different factors and morphometric characteristics. The distribution across different habitats was measured by component canonical analysis (CCA) and genetic distance was analyzed by hierarchical cluster. The average standard lengths of H. wyckii from the Koto Panjang Reservoir, Kampar Kanan and Kampar Kiri rivers (Mean±SD) were 428±15.78, 432.52±66.11 and 425.86±50.41 mm, respectively. Twenty-nine morphometric characteristics were measured. There was a 68.96% difference obtained in samples collected at the Koto Panjang Reservoir and Kampar Kanan river. There was a 95.55% difference obtained in the Koto Panjang Reservoir, Kampar Kiri river and a 100% difference obtained in the Kampar Kanan and Kampar Kiri rivers. The main differences in morphometric characteristics included inter orbital distance, length of adipose-fin base, predorsal length, length of front dorsal fin-front pelvic and depth of caudal peduncle. The Mahalanobis distance between fish from the Koto Panjang Reservoir and Kampar Kanan river demonstrated that both types originated from a single population. It was concluded that more favorable morphometric characteristics of H. wyckii were found in the Kampar Kanan river compared to those from the Koto Panjang Reservoir and Kampar Kiri river.

Model Dinamik Pengelolaan Jasa Ekosistem Waduk Koto Panjang Kabupaten Kampar Riau

The study aims to establish the management model of ecosystem services Koto Panjang Reservoir.The approach used in this modeling is the Dynamic Modelling. The results showed the value ofprediction error of the simulation results based on the data used was in the range 0.4 % - 4.64 %. Thesimulation results show the value of economic growth in 2020 will reach its peak value Rp.3,3 billion.The economic value of the total economic value of the four main activities of the utilization ofecosystem services Koto Panjang Reservoir namely; KJA cultivation of Rp.1,1 billion, tourism Rp.1,6billion, fishing by paddle for 60 million, fishing by fishing boat engine at Rp.489 million. Modelscenarios developed by increasing the KJA growth of 30% and 100% for tourism, managed toincrease the total economic value of Rp.5,08 billion from previously around Rp.3,3 billion or anincrease of approximately 53.95%. The increase in the economic value derived from an increase inthe economic value of Rp.1,56 billion KJA activities and improvement of the economic value oftourism activities Rp 2,9 billion.
