TNKS has a very important role in forest management, from sustainability to the utilization of forest products for the surrounding communities that use TNKS land for coffee and cocoa plantations. So that forest sustainability can be maintained and can actually provide sustainable benefits to the community around the forest. The TNKS Center provides coffee grinding machines, which can be used by the coffee plantation community. To drive the coffee grinder, a generator is used, where the fuel is carried directly by the coffee planters. To provide sustainable benefits, river water is used as alternative energy to create a pico-hydro power plant, as a driving force for coffee grinding machines, because the TNKS post is only used by the forest police from morning to evening, so there is no need for lighting at night. Therefore, it is necessary to conduct a site survey to determine the location of the weir, channel, and turbine housing. Likewise, data collection of water discharge and different heights of falling water from the tranquilizer tank to the turbine house. From the results of the survey and calculations obtained a capacity of 6 KW, using a crossflow turbine with a head of 12 meters and a discharge of 100 liters/sec. The Bangun Rejo TNKS Command Post is a camping ground location that supports the construction of PLTPh which needs to be realized immediately. With the existence of this pico-hydro power plant, the community of coffee planters, no longer needs to buy fuel and no longer use generators, but pico-hydro electricity at the TNKS post.

Indonesia is the world's largest palm oil producer with a land area of 14.3 million as of 2019. With this area, it will produce biomass in the form of replanted stems, midribs, empty palm oil bunches (TKKS), shells and fruit fibers. Biomass waste, including palm oil solid waste, has the potential to be used as raw material for renewable energy or bioenergy. This study aims to utilize palm oil plantation waste into bio oil and bio briquettes. The raw materials used in this study were empty oil palm fruit bunches (TKKS) and palm oil shell waste. Bio oil is made by the pyrolysis process. This research produces pyrolysis products, namely bio oil as a substitute for diesel fuel from EFB waste and from shells to produce bio briquettes. Found in pyrolysis products, namely bio-oil, aromatic compounds, aliphatic hydrocarbon compounds, acid compounds and hydrocarbon compounds. Hydrocarbon compounds are compounds that exist in fuel oil. In OPEFB bio oil, 19 types of hydrocarbon compounds were found. Meanwhile, bio briquettes from oil palm shells produce a calorific value of > 5000 which has met the Indonesian national standard (SNI) 01-6235 in 2000. Meanwhile, the water content value meets the Indonesian National Standard, which is a maximum of 15%.

Based on the survey results in the last seven years (2010 - 2017), palm plantations in the Pakning Asal area, Bengkalis Regency experienced fires with different frequencies. Some lands that not burned, once burned and several times burned. The burned areas can affect the composition and nutrient content of the soil. Burning peatlands cause irreversible drying due to the heating of the peat. This study aimed to analyze the effect of fires with different frequencies on the total Fe, Al, Mo and C/N content. Total Al and Mo content was determined using Atomic Absorption Spectrophotometer. The total Fe and C content was analyzed using UV-Vis Spectrophotometer. Total N was analyzed using the Kjeldahl method. The results showed that the total Fe, Al, and Mo content increased in the soil burned once and the C/N ratio increased with the increasing frequency of fires. The total Fe, Al, and Mo content in the soil burned once was 69.20 mg/Kg, 33.83 mg/Kg, 2.16 mg/Kg and the C/N ratio increased from 16.51 to 25.31, respectively. The impact of different fire frequencies affected the chemical content of the soil. Land fires have positive and negative impacts. The positive impact increased pH of soil palm plantations, while the negative impact caused air pollution and damage to soil structures.

The research aims to estimate the manure production and calculate the methane gas produced by the pig free-ranging system in Gaya Baru and the surrounding of Wosi Market in Manokwari. This research is conducted from May to June 2018. The methods used in this study are observation, interviews, and literature study. Direct observations in the field are carried out by calculating the pig population and estimating the body weight by measuring body length and chest circumference according to the Winter formula. Furthermore, the calculation of the amount of fresh dung (KTS) of pigs is carried out. The parameter observed in this research is the methane gas produced by the systems. Research is conducted by observation, interview, and literature review with a descriptive statistical approach. The free-ranging pig systems in Gaya Baru and its surroundings produce ammonia at 0.246617 ppm/day, biogas of 10.95m3/year, equivalent to 3996.75m3 per year, and methane of 10.85 m³ per day, or equivalent to 130.18 m³ per year. If this condition is allowed to continue, this will have a social impact, but also environmental and health problems around the research sites.

Climbing perch (Anabas testudineus) is one type of swamp fish that has the potential to be cultivated. The obstacle faced in the development of quail aquaculture is its slow growth because it takes 6-7 months to reach a length of 8-10 cm and a weight of 15-16 grams. The food for quail is usually eaten by aquatic plants such as water lettuce (Pistia stratiotes), weeds, other small animals, and insects. Feed is one of the main factors that can support fish breeding. As a place for fish to live, water quality is strongly influenced by physical and chemical factors of water such as temperature, dissolved oxygen, pH, ammonia, nitrite, and nitrate. Because the use of freshwater media added with salt has several advantages, it can inhibit the growth of fungi and increase antibodies against disease attacks. The objectives and plans of this research are. To determine the effect of different doses of maintenance media on the spawning of quail (A. testudieneus Bloch). Morever, to find out and provide the best optimal dose for rearing quail (A. testudieneus Bloch). It find out the best dose for spawning quail (A. testudieneus Bloch). It be used as a reference for further research ?. Hopefully, this study can provide benefits and insights for the cultivation technology of quail (A. testudieneus Bloch) either continuously or in a way that is good for its living media.

Peat areas have unique characteristics as wetlands on land but are highly flammable if there are El Nino symptoms. The peat area has a protection function and a cultivation function and this is important for the life of living things. To date in 2021, where this research was conducted, the condition of the peat area in Bukit Batu District, Bengkalis Regency is very easy to burn, this requires a sustainable peat area management strategy from the ecological, social, and economic aspects so that fires do not occur in the future. This research can be useful for stakeholders to manage peat areas in a sustainable manner by taking into account the ecological, economic, and social aspects. Repeated fires in the same location make peat even more degraded. For this reason, it is necessary to manage post-fire peat areas, so a management strategy using prospective analysis is needed. The prospective analysis is a method that can be used to find strategies that can be applied in the future. The results of the prospective analysis in this study recommend that there are three strategies that need to be applied, from the ecological aspect, namely the conservation and rehabilitation strategy, from the social aspect, namely the MPA-preneurship strategy and from the economic aspect, namely the strategy of using burned land. These three strategies can be carried out simultaneously and holistically by involving many stakeholders in peat areas.

To date in 2021, where this research was conducted, the condition of the peat area in Bukit Batu District, Bengkalis Regency is very easy to burn, this requires a sustainable peat area management strategy from the ecological, social, and economic aspects so that fires do not occur in the future. This research can be useful for stakeholders to manage peat areas in a sustainable manner by taking into account the ecological, economic, and social aspects. Repeated fires in the same location make peat even more degraded. For this reason, it is necessary to manage post-fire peat areas, so a management strategy using prospective analysis is needed. The prospective analysis is a method that can be used to find strategies that can be applied in the future. The results of the prospective analysis in this study recommend that there are three strategies that need to be applied, from the ecological aspect, namely the conservation and rehabilitation strategy, from the social aspect, namely the MPA-preneurship strategy and from the economic aspect, namely the strategy of using burned land. These three strategies can be carried out simultaneously and holistically by involving many stakeholders in peat areas.","PeriodicalId":150200,"journal":{"name":"Dinamika Lingkungan Indonesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131267461","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}
Currently, the Indonesian nation is facing challenges that require human resources adapt to the COVID-19 pandemic situation. Has the discovery of a vaccine and the implementation of ongoing vaccination does not guarantee avoid the spread of COVID-19. Thus, the obligation to implement the protocol health continues. One of the health protocol policies is provide adequate hand washing facilities for the management public facilities. The behavior of washing hands with soap is part of the program Clean and Healthy Life Behavior (PHBS) in the household. Washing hands Using soap is an effective step to break the chain of transmission COVID-19. However, please note that hand soap contains detergent. The results of using detergent (hand soap) will produce residue in the form of liquid waste, which is then discharged into the environment directly cause the balance of nature to be disturbed, namely soil pollution which causes capable of changing soil pH, changing mineral content and nutrient disturbances from soil for plant life and polluted groundwater sources. On research In this case, identifying and analyzing the waste from washing hands with soap in public facilities can affect the environment and the amount of content detergents that dissolve in water and whether nature can neutralize water pollution that occurred before and after the COVID-19 pandemic.
