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.  Keywords: ecosystem services, reservoirs, total economic value, dynamic modelling

The purpose of this research was to determine capture fisheries status in a sustainability perspective based on ecology, economy, social, technology and ethic dimensions. A data analysis method which used was Multidimensional Scaling with RAPFISH technique. All dimensions in this study were based on FAO’s attribute and was modified based on fisheries condition in research location. Score multidimensional analysis is 45,69. These results indicate that the multidimensional sustainability status of capture fisheries on Bangka Island is in a less sustainable status. The result showed that ecology was the dimension which has the lowest score in order to support captured fisheries sustainability in Bangka Island. The result also formulated sensitive attribute in every condition and gave management recommendations for the sustainability of captured fisheries based on that attribute. This study showed the importance of dimension integration and stakeholder’s teamwork multisectoral in order to manage the sustainability of captured fisheries.

The mangrove ecosystem is one of the ecosystems that has high productivity in coastal and marine areas, especially in supporting the productivity of fishery resources. This is due to the function of the mangrove ecosystem as ecological and socio-economic. Therefore, to determine the high level of mangrove utilization in the coastal area of Siak Regency, an economic assessment of mangrove ecosystem services is necessary. This research aimed to study quantified mangrove ecosystem services in Siak Regency, Indonesia. Methods for data collection included field survey and interview, performed between July - August 2020. The economic value assessment comprised valuation on following service groups, i.e. supporting, provisioning, regulating and cultural services. The results showed that the economic value obtained from all studied services reached IDR 29,180,852,208 per year, IDR 24,747,680,000 per year, IDR 90,291,590,933 per year and IDR 9,245,925,366 per year, respectively. In conclusion, a total amount of economic value for mangrove ecosystem services in Sungai Apit District, Siak Regency was IDR 153,466,048,507,014 per year, which was equivalent to IDR 300,090,044,0 per hectare per year.

Research has been conducted in Kepenghuluan Melayu Besar Subdistrict Tanah Putih Tanjung Melawan in January to February 2018. The aim of this research was to analyze the indicator of the presence of Aedes aegypti mosquito larvae on 3M Plus movement in Kepenghuluan Melayu Besar Subdistrict Tanah Putih Tanjung Melawan and analyze the effect of 3M Plus movements and impacts socio-economic on the existence of Aedes aegypti mosquito larvae in Kepenghuluan Melayu Besar Subdistrict Tanah Putih Tanjung Melawan. The results showed that 3M Plus movement affected to decrease larva population in an area. The impact of the 3M Plus movement was viewed from an economic aspect, namely the costs incurred was cheaper than before the 3M Plus movement. The social impact gained from 3M's movement Plus the empathy and feeling of mutual cooperation in the community, the use of recycled goods increases the aesthetic value because the use of used goods to be used as crafts, feeling safe and comfortable and not panicking when there is an attack of DHF and the emergence of clean living behavior and healthy in the community.

Background: The objective of the present study was to examine the effect of Ovaprim dosage on the latency period, relative number of ovulated eggs, fertilization, hatching, and survival rates of the siban fish, Cyclocheilichthys apogon. Methods: Three dosages of Ovaprim were tested in this study, namely 0.3 ml kg-1 of broodfish body weight, 0.5 ml kg-1 body weight, and 0.7 ml kg-1 body weight, plus control (without Ovaprim).  Results: The results showed that the best latency period, relative number of ovulated eggs, fertilization, hatching, and survival rates were obtained at a dosage of 0.7 ml kg -1 body weight. Conclusions: The best dosage of Ovaprim for siban fish from the dosages tested, was determined to be 0.7 ml kg-1 body weight.

Coastal ecosystems on small islands have a large enough pressure to be inversely proportional to a large island due to various resource capabilities and limited supporting factors. Mangrove is one of the ecosystems on the coast of a small island that is susceptible to disturbance because it is close to human activities. This study aimed to determine the mangrove ecosystem management strategy on the coast of the Siak Regency. The research was conducted from July to August 2020 using survey and interview methods. Data analysis used the Analytical Hierarchy Process to determine the mangrove management strategy. The results showed that community involvement is a priority for managing sustainable mangrove ecosystems with the assistance of the Government and NGOs. Management priority factors, namely ecology, while still paying attention to economic, social, institutional, and technological concerns.

The research was conducted on Pasumpahan Island in Bungus Teluk Kabung Sub-district, Padang, West Sumatera, Indonesia.
