Studies on phosphate levels (total, polyphosphate, and orthophosphate) have been carried out in the Lamat Muntilan watershed. 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.

Mudal River ecotourism is located in the Menoreh Hills which is a geological protected area and the area around the springs in the RTRW of Kulon Progo Regency. Since 2015 the Mudal River has been used as a tourist spot in the ecotourism category. 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 two results obtained are still far above the existing visitors to the Mudal River Ecotourism so the carrying capacity of ecotourism activities is still in accordance with the value of the carrying capacity of the area and the real carrying capacity.

The tofu industry in its production process uses ± 25 liters of water per 1 kg of soybean raw material. Soybean used as raw material for tofu contains protein, carbohydrates, fat, and other nutritional ingredients so that the resulting liquid waste contains high organic matter that has the potential to pollute the environment with a value of Biological Oxygen Demand (BOD) of 467 mg/L and Chemical Oxygen Demand (COD) of 668.2 mg/L. Efforts to control water pollution can be overcome by processing biotechnology using an activated sludge system. This study aims to analyze the effectiveness of polluted water sediment as the main ingredient of activated sludge in reducing levels of Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) and to determine the growth rate of microorganisms in the acclimatization process. This research was carried out on 4 different composition variations in batches under aerobic conditions using an aerator and a pump as a stirrer. The results showed that the composition of the sludge in treatment IV, namely the composition of the sludge consisting of (60% Waste, 40% Nutrients, and cultured RPH sludge) was the best composition at 60 hours of aeration with the effectiveness of removing BOD concentration of 90.10% and COD concentration. amounted to 87.41% or achieved a reduction value of 46.21 mg/L of BOD concentration and 84.14 mg/L of COD concentration with a specific biomass growth rate of 0.054 day-1.
豆腐行业在生产过程中，每生产1公斤大豆原料要使用±25升水。作为豆腐原料的大豆含有蛋白质、碳水化合物、脂肪等营养成分，因此产生的废液中有机物含量高，具有污染环境的潜力，其生物需氧量(BOD)为467 mg/L，化学需氧量(COD)为668.2 mg/L。控制水污染的努力可以通过使用活性污泥系统处理生物技术来克服。本研究旨在分析受污染水体沉积物作为活性污泥的主要成分对降低生物需氧量(BOD)和化学需氧量(COD)水平的有效性，并确定驯化过程中微生物的生长速度。在好氧条件下，采用曝气器和泵作为搅拌器，对4种不同的组分分批进行了研究。结果表明，处理IV的污泥组成，即由(60%废弃物、40%营养物和培养RPH污泥)组成的污泥组成，在曝气60 h时为最佳组成，去除BOD浓度为90.10%，COD浓度为COD。生物量比增长率为0.054 d -1, COD还原值分别为46.21 mg/L和84.14 mg/L，达到87.41%。

Togok is a fishing gear in the form of a conical net body whose arms are on two poles and the success of catching it relies on currents, togok fishing gear is used to catch Rebon shrimp (Acetes japonicas) but in its operation, many catches are found bycatch. The high bycatch will have an impact on capture sustainable fisheries, one of the efforts to reduce bycatch is by using BRD (Bycatch Reduction Devices), the use of BRD has been widely carried out on trawl fishing gear but on togok fishing gear, it has never been done. This study aimed for knowing the reduction in catches of main catch, bycatch, and discard the togok fishing gear that has been installed with rope BRD and knows the reduction in catches of shrimp and fish species. This study uses experimental fishing, namely by carrying out direct fishing operations with local fishermen for 20 days of catch. The reduction of togok catch using BRD type rope BRD in the main catch is 8.4%, in bycatch is 11.8% and discard is 17, 1% and the reduction in catch of shrimp species ranged from 8,4% - 13,5% and reduction in catch of fish species ranged from 10,9% - 22,6%.

The paradigm transition in agricultural science leaves many problems. The impact of using pesticides in the past has had a negative impact, both on the environment and on human life. Agricultural scientists as pesticide product developers should be responsible for their scientific products' impact. This research is a philosophical study that aims to analyze the responsibility of scientists on the phenomenon of pesticide use by using the axiology of science. This research is a philosophical reflection on the development of pesticides in agriculture as a controversial issue, both structurally and normatively. The results show that there are two responsibilities of agricultural scientists that can be contradictory: social responsibility to meet the community’s food needs and moral responsibility to pay attention to the environmental impacts caused.

Kenegerian Sentajo protected forest serves as a protector of the community and natural life support systems, regulates water systems, prevents floods, controls erosion, and maintains soil fertility. 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.

This article aims to find the dynamics of actor interaction in strengthening oil palm policies with examples of cases of oil palm policy in Riau. The background is the phenomenon of the broader spectrum of conflict in Riau early in the reformation. How will the interaction pattern of actors related to oil palm policy issues take place in post-reform Riau? 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. It is a fact that the nature of local politics is considered in strengthening the policy on palm oil management in Riau.

Research on Soil Macrofauna as Bioindicator in Plantation Areas Given Palm Oil Mill Liquid Waste as Fertilizer was conducted in 2021. Samples were taken in Long Bed, Flat Bed, and Control areas using Purposive Sampling and Squares and Hand Sorting methods. Each location is determined by 9 sampling points. Soil macrofauna samples were identified in the USU FMIPA Ecology laboratory. From the results of the study, there were 3 soil macrofauna phyla, namely the Annelida phylum, which consisted of 1 class, 1 order, 2 families, and 2 species. Phylum Arthropoda consists of 5 classes, 10 orders, 16 families, and 27 species. Phylum Mollusca consists of 1 class, 1 order, 1 family, and 1 species. The highest population density (K) was obtained from the species Macrotermes gilvus, which was 81.10 individuals/m2 in the Control area, followed by Ponthoscolex corethrurus at 78.81 individuals/m2 in the Flat Bed area. The highest relative density (KR) was found in the species Macrotermes gilvus, which was 49.1% in the control area, followed by Ponthoscolex corethrurus at 46.84% in the Long Bed area. The highest frequency of presence (FK) was found in the Ponthoscolex corethrurus species, which was 100% in the Control and Flat Bed areas, and 88.88% in the Long Bed areas. Species that can live and reproduce well as bioindicators are Ponthoscolex corethrurus in the Long Bed area, followed by the Flat Bed and Control areas. The highest diversity index value was found in the Flat Bed area, which was 3,831 with the criteria for diversity being high, the distribution of the number of individuals for each species was high, the community stability was good and the soil community had not been polluted, while the Equitabilitas value was 1,258 with the criteria for high uniformity, stable community. The application of palm oil mill effluent as fertilizer to the plantation area can increase the life of the soil macrofauna, and the physical-chemical properties of the soil.
