A detergent is an approach to the amount of waste disposal of various types of phosphate in the Lamat river. High levels of phosphorus cause eutrophication, which can cause various human health problems. This study aims to determine the levels (total, polyphosphate, and orthophosphate) and compared rain and dry season with water quality standards that have been agreed upon nationally as well as theoretical studies on eutrophication pollution. This research uses the UV-Vis Spectrophotometer method by utilizing the interaction of ammonium tartrate and potassium antimonyl tartrate on orthophosphate ions to form phosphomolybdic acid which is then reduced by ascorbic acid to a modern blue color which is proportional to the number of orthophosphate ions. This modern blue color is measured at a wavelength of 880 nm. The result data showed that the average total phosphate levels of river water of 0.240 ppm in the rainy season and 0.204 ppm in the dry season, for polyphosphates were found at 0.032 ppm in the rainy season and 0.064 ppm in the dry season, while orthophosphate 0.051 ppm in the rainy season and 0.101 ppm in the dry season. In the dry and rainy seasons, there were specific differences between them. This level surpassed Peraturan Pemerintah Republik Indonesia Nomor 82 Tahun 2001 about concerning Management of Water Quality and Control of Pollution Water, was not suitable for consumption directly or indirectly specifically for human needs, but if it was used for animals and plants it is still feasible. The level of all phosphate species triggered the formation of eutrophication.","PeriodicalId":150200,"journal":{"name":"Dinamika Lingkungan Indonesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122987339","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These ecotourism activities have increased significantly from year to year when viewed from secondary visitor data for 2015-2018. The study was conducted to determine the value of the carrying capacity of the area and the real carrying capacity which is an effort to prevent damage that occurs in ecotourism areas in protected areas. The method used in this research is a survey and field method. Data on the parameters of carrying capacity and area and real carrying capacity were obtained from the survey and field activities. Based on the results and data processing carried out, it was found that the carrying capacity of the area (DDK) was 701 people/day (consisting of DDK utilization of playing water 637 people/day, DDK utilization of sitting relaxed 57 people/day, and DDK utilization of camping 7 people/day). Meanwhile, the real carrying capacity value is 1151 people/day.

The management of forest resources by the community is quite unique because it is still communally regulated, which is closely related to the kinship system and leadership of local indigenous peoples. This encourages the formation of strong communication relationships or interactions between communities and their forest resources. However, in reality, the indigenous people of Sentajo Regency have not obeyed the customary rules, which resulted in the forest that was originally preserved has begun to be converted to function by the community. The forest, whose precedence is beautiful, has now partially turned into plantation land and building houses for residents. This study aims to 1) Analyze environmental communication planning in the preservation of the Kenegerian Sentajo protected forest in Kuantan Singingi Regency; 2) Analyze the implementation and evaluation of environmental communication in the preservation of the Kenegerian Sentajo protected forest in Kuantan Singingi Regency. This research uses qualitative methods. Data collection techniques are carried out through interviews, observations, and documentation. Informants totaled 8 (eight) purposively determined persons. The data analysis technique used in this study is carried out in several stages, namely data reduction, data presentation and drawing conclusions, and testing the validity of the data using triangulation. The results of this study show that: First, the planning stage begins with an assessment which includes analyzing the situation and identifying the problem of environmental damage that occurs, Analysis of parties or actors involved, Then, planning which includes developing communication strategies, motivating and mobilizing communities with the division of indigenous territories and the selection of media and communicators. Second, this implementation stage begins with the production stage, which includes the design of the message to be delivered. Furthermore, the implementation stage is in the form of the application of customary norms, the application of socio-cultural values, and community empowerment through tree and rattan planting, their implementation, and documentation after evaluation.","PeriodicalId":150200,"journal":{"name":"Dinamika Lingkungan Indonesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121008113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The background is the phenomenon of the broader spectrum of conflict in Riau early in the reformation.

The theory used by the local political economy and the method used determine; (1) Actor's political preferences; (2) Actor's tips and strategies; and (3) How do actors organize themselves into coalitions? This study found that since the OTDA policy was implemented in Riau, the dynamics of national politics changed, from a central style to a decentralized one. This change in political context resulted in mixed responses from local actors in Riau. Local actors are becoming more critical because of the law on the use of natural resources. The activities of these different actors produce different reactions to implementing policies in the plantation sector. The response of these elites could be a result of different positions. Since the reformation, the intensity and spectrum of political dynamics have increased and expanded and its disclosure in public debate has become more assertive.
