Abstract

Environmental pollution that occurs in Tanjungpinang City, cannot be separated from the pollution of the aquatic ecosystem. Water pollution is caused by the presence of waste from residential activities, shops, industry, and other activities that produce waste. Likewise, what happens in the waters of the Sungai Jang, the activities of settlements, shops, industry can cause water pollution in this area, so a study is needed to see the extent of environmental pollution. The indicator used to determine the level of water pollution is by looking at the saprobity index through the phytoplankton community. This research was conducted by dividing the research stations based on differences in activity, namely; station 1 (settlements), station 2 (mangroves), station 3 (shops, industry), station 4 (reclamation). The results showed that the composition of the phytoplankton species found in the waters of the Sungai Jang, Tanjungpinang consisted of 17 species which were classified into 5 divisions. Diatomae types have the most number of species among other divisions, and the most dominating. The dominance of phytoplankton from the class Bacillariophyceae (Diatomae) cannot be separated from the role of nutrients in the water. The average saprobic index value of -0.39 is classified as Moderately Polluted (Meso Saprobik). Pollution that occurs is a result of organic waste from existing activities, causing an increase in nutrients. From the results of measurements in the field, the nutrient content (nitrate and phosphate) in the waters of the Sungai Jang had exceeded the quality standard.

Abstract

In Bandar Alai Kari, Kuantan Tengah Sub-district, Kuantan Singingi Regency, Riau, there is a Buaya Lake. According to the history, the Buaya (crocodiles) Lake, used to be a place for river crocodiles to live (an area of approximately 4.5 ha). To obtain data on the value of the lake's conservation status (ecological value), a rapid assessment method is used using the ECELS index. Observations in the field and with the help of drones to observe the components of the ECELS index assessment, the index value is less than 30. From this value it can be concluded that the Bandar Alai Kari crocodile lake is in a very bad conservation status and needs to be restored

Abstract

Intensive agricultural practices in the upper land of the Indragiri river bring about problem to  oxbow-lakes spreading out along in the middle and downstream of the river. Danau Sungai Sorik (DSL) typically included to oxbow-lake, situated in the middle part of Indragiri River, one of four big river in Riau Province, Sumatera. Since the catchment area of the lake were totally urban, accordingly the dynamic equilibrium of lake ecosystem were shifted. The lakes were reportedly degraded in terms of hydrological regime, high sedimentation, fully vegetated and low biological diversity. The local government has repeatedly normalized the depth of the lake in related to development of water attraction, restocking of invading species of fish, cage culture and rice field along the edge of the lake. The present papers aimed at characterizing and assessment of physicochemical and biological properties of the water. Further, potential threats on the sustainability of the lake were assessed. Based on chemical properties of water including BOD5, phosphate and Nitrate range were of (3.26-7.43), (0.11-0.13) and (0.229-0.433) m/L, respectively, were categorized into un-equilibrium or slightly polluted. The water transparency appeared low (25-29) cm, the pH of 6.0-6.5) and temperature of 31-32 0C. Apparently, the diversity index (H), dominancy index and similarity index of phytoplankton ranged from (0.9110-1.2211), (0.3201-0.6136) and (0.3939-0.6290, respectively. It suggested slightly dominated by certain species

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

Lake Timbang Bunga Pengantin, an oxbow lake, has been a favorite tourist destination in Kuantan Singingi Regency in the last decade. The lake of 12 ha in area were used for multi purposed locally livelihood indluding tradisional rice field in the bank of the lake, irigation, fishing ground, fish cage culture, floating resdtaurant and water attraction tourism. As such the lake faced heavy burdens and could interferred the sustainability of the lake. To overcome the environmental problem for sustainability of the ecosystem,a management sustainable strategy need to be formulated with multi criteria of consideration. The present study applied multi-dimentional scaling (MDS) approach following RapLake. The result showed that, the sustainability state of Danau Timbang Bunga Pengantin based on ecology, technology, regulation, were 60,6%,  62,8 %, 70,2%,  respectively, which categorized fairly sustainable, while based economy and sociocultural categorized less sustainable which index of  35.3 % and 44,5 %,  respectively. It revealed that 11 atributes namely; water fertility of lake, fish biodiversity, water condition, tourist potency, capital, fishing dependency, infrastructure, law enforcement, fertilizing of rice field, social  conflict and community empowerment, which driven factors of the management of the lake. The management strategy should start on developing supporting tourism facilities such as econo-lodging, home stay, new attraction, road improvement and amenities. Further the management develop a locally unique attraction and increase local knowledge. Another aspect of important was promotion of the tourist destination through media.

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.
