Abstract

Longtail Shad are endemic in the waters of Riau and especially in the waters of Bengkalis Regency and have omnivore characteristics, namely eating plants and also from groups of animals. The purpose of this study is whether fish is the best in choosing food depending on the type of food or not. This study uses a survey method, which was conducted in Bengkalis waters from May to June 2019. In this study, it was shown that fish is the best in choosing food depending on the type of food available (selective), so that if the type of animal, in this case, is crustacean and crab. There are a lot of small crabs, then the worst fish eat the group of crustaceans and small crabs. However, if what is available is only from the algae group, the best fish will only eat from the algae group. So that in the stomach of the Longtail Shad are not found both types of food at once

Abstract

Pelalawan District has several sleep peatland areas, which overgrown with grass weeds. This area has the potential to become a sources of beef cattle farming feed in the intensive livestock system. The potential of the beef cattle market is still prospective as a source of protein demanded by the majority peoples. This study aims to valuate and evaluate the potential carrying capacity and economic value of sleep peatlands area as forage provider. This research method was descriptive approach. The data used in this study is secondary data collected from various reliable sources and previous related research. Carrying capacity was expressed by estimate the land's ability to provide cattle feed. Economic analysis is carried out by estimate profit which obtained from the intensive beef cattle farming system. The analysis results shows that sleep peatland areas that potential to supports intensive beef cattle farming around 3,210 ha with carrying capacity = 9,078 cows/year. This carrying capacity was higher than the current beef cattle population around 1,992 cows. The potential economic value reaches IDR 45.56 B/year, which is higher than the current actual economic around IDR 9.99 B. It’s necessary to improve management aspects by integrating the development of intensive cattle farming systems with community-based peatland restoration programs, corporate social responsibility, and SDGs achievement commitments. This requires a solid partnership among stakeholders that will increase the management dimension towards a more sustainable way.

Abstract

Natural food enrichment, especially water fleas, is an important effort in improving the performance of freshwater fish larvae. The enrichment process that will be carried out is influenced by several factors that need to be considered, namely the dose of vitamin supplements, pH, and time of enrichment so that the vitamins can be absorbed by the intestines and the nutritional value of water fleas increases. This study aims to examine and determine how the effect of the dose of viterna, water pH, and time of enrichment on the rate of the fulfillment of the gut of water fleas by viterna. This research was conducted from January 3 to 7, 2022 at the Laboratory of Fish Hatchery and Breeding, Faculty of Fisheries and Marine Science, Riau University. The treatment in this study is the rate of the fulfillment of the water fleas' intestines during the water fleas natural feed enrichment technique which was carried out with three different pH test factors, different doses, and different enrichment times. The results showed that the water fleas enriched for 5 hours, at a pH of 7 and a dose of 60 ml/L of viterna showed the best filling rate of the water fleas' intestines at 100%, and the water fleas' intestines were filled with viterna compared to other treatments.

Abstract

Eco-Forest green open space (GOS) development is one of the ways to achieve sustainable urban development in Pangkalan Kerinci City. The information of structure and composition of the natural tree species growing in the green open space was required as a basis to formulating future rehabilitation strategy. This study aims to analysed the diversity and composition of tree species at the development area of Eco-Forest GOS. The data used in this study was primary data of tree species, dbh, frequency and density. Data collected by field observation using a systematic sampling method. Data analysis was carried out by estimate the diversity parameters including diversity index, richness, and evenness. Species composition assessed by important value index. Spatial interpolation of the diversity index and tree density was carried out by spline interpolation method using ArcGIS 10.7 software. The analysis result shows that the diversity of natural tree species was decreases by increasing the live cycle of tree. There are three dominant species in this location, which Ilexcymosa, Litsea firma, and Stemonurus secundiflorus. Spatial analysis shows that 51.5% of the green space area classified into low diversity and density category, while 13.2% was classified as high diversity and density class. Efforts to achieved the successful of GOS management by use the information of vegetation’s structure and composition as one of the inputs to develop the regeneration and rehabilitation system. At the same time, it is necessary to increases the dimensions of human, institutional and financial management that supports biodiversity conservation in the green open space

Abstract

Ecotourism management of North Mareje Mountain Forest Area (NMMFA) is one of ways to achieved sustainable development goals (SDGs) in Central Lombok District. The lack of ecotourism economics value information causes investment for its development runs relative slowly. This study aims to valuate and evaluate the economics value of ecotourism development in NMMFA. The data used in this study includes number of tourist visits during 2018-2019, tourists visit frequency, travel costs and their socio-economic characteristics. Data was collected by interviewing NMMFA’s managers and tourists using questionnaire. Economic valuation analysis was carried out by using the traveling cost method (TCM). Economic evaluation diagnosed using paired t-test by comparing observed versus potential economic values. The Analysis result shows that the willingness to pay (WTP) of tourists whom visit to NMMFA=IDR. 347.579/visit with  economic value = IDR 3,72 B/year. The economic evaluation results explains that the observed economic value = IDR. 986,78 M/year is smaller than the potential economic value of it carrying capacity ones =IDR 127,05 B/year. To improve economic development, it required a new paradigm of forest management by making current conservation activities become a conservation business and improving sustainable ecotourism management aspects.
