This article discusses the analysis of the physico-chemical parameters of water in the Serayu River, Banjarnegara, Indonesia during the dry and rainy seasons. The parameters to be measured are heavy metals, alkalinity, pH, temperature, TDS, TSS, and corrosivity. The sampling location is at the mouth of the Serayu River, where Serayu River water is one of the Mrica Reservoir water sources used for hydroelectric power plants. (PLTA). When the samples were taken in the rainy and dry season in 2018. The results showed that in the rainy season, the surface water pH of the Serayu River estuary was 6.61; the TDS was 178 mg/l; the TSS was 62 mg/l; the BOD was 6.66 mg/l; the COD was 33.31 mg/l; and the nitrate was 4.03 mg/l. Meanwhile, in the dry season, the pH was 8.15; the TDS wa 121 mg/l; the TSS was 55 mg/l; the BOD was 6.35 mg/l; the COD was 31.77 mg/l, and the nitrate was 3.08 mg/l. All physical and chemical parameters meet the quality standards required in Indonesian Government Regulation No. 82 of 2001 concerning Management of Water Quality and Class III Water Pollution Control. The surface water of the Serayu River estuary is weak corrosive which means it is safe for hydropower activities. In general, in the rainy season the chemical physics parameters of the Serayu River estuary water level are higher than the rainy season.

The negative impact of Illegal Gold Mining / IGM on the environmental sector in Batang Asai District, Sarolangun Regency, Jambi was investigated through a descriptive qualitative method. The purpose of this study was to determine the negative impact of IGM activities to several ecosystems, the effect of IGM on community activities, and some efforts to reduce IGM. The instruments of data collection included observation, interviews, and documentation. Data were analysed through data reduction, data presentation, and conclusion withdrawal. The results showed that IGM activity had a negative impact on the environment namely noise pollution, dust, degradation on the quality of Batang Asai River, forest conversion, river siltation, the emergence of large holes, overburden, soil abrasion, the disappearance of Meranti plants (Shorea sp. ) and Damar (Agathis Damara). Besides that, other impacts were the declining population of Semah Fish (Tor sp.) which had become the special characteristic of fish in the area. Some efforts were made by the government to overcome and foster IGM activities, e.g. by providing counselling and sanctions in a judicial and non-judicial manner that was carried out continuously.

Coastal abrasion has caused the destruction of the mangrove forest in Mojo Pemalang Village. Thus, a preliminary study of communities’ literacy about conservation at Mojo Village, Pemalang, was required to develop the potential of mangrove forest ecotourism. This study aimed to understand the fishermen’s literacy about conservation at Mojo Village, Pemalang related with the development of mangrove forest ecotourism through the Community Learning Center (CLC). The type of research was qualitative descriptive. The research subjects were fishermen in Mojo Village, Pemalang, Central Java, Indonesia. The results of a preliminary study of six indicators of environmental literacy and conservation developed by the North American Association for Environmental Education (2011) and Rush et al. (1999) are as follows: ecological knowledge = 6.02%, verbal commitment = 6.02%, environmental sensitivity = 6.02%, identification = 12.04%, issue analysis = 6.02%, and real commitment = 6.02%. The overall percentage was 42.14% and was included in the low category. The results of the preliminary study indicated that Mojo fishing communities’ literacy about conservation of the environment towards mangrove forests still needed to be improved. A solution suggested based o the results of a preliminary study was the implementation of mangrove ecotourism Community Learning Center (CLC), conducted through several pieces of training, including conservation training, education training, tourism training, and economic training.

The increased number of tourists in Batu City has resulted in traffic congestion, which led to the increase of emission contributing to GHGs effect and caused global warming. According to Presidential Regulation Number 71 of 2011, each region is required to conduct a national inventory of GHGs emission, in order to determine the appropriate adaptation and mitigation strategies in reducing the GHG emission. This research aimed to reduce the GHGs emission and to determine the appropriate adaptation and mitigation strategies in Batu City especially in the transportation sector. IPCC Guidelines 2006 was used as the method to calculate GHGs emissions. Such method allowed the researchers to determine the emission level by using secondary data obtained from the relevant institution. Determination upon adaptation and mitigation strategies was on the basis of several scenarios of emission level reduction while the prioritized strategy selection was based on the Analytical Hierarchy Process method. This research revealed that the GHGs emission with business as usual scenario in 2030 contributed by transportation reached 2,072.64 Gg of CO2 while the greatest reduction of GHG emissions amounted to -6.13% taken from the scenario of Intelligent Transport System application. More importantly, the researchers figured out that the prioritized adaptation strategies should be the improvement of Urban Open Space and public transportation rejuvenation for the mitigation.

Land subsidence in DKI Jakarta influenced by several key factors, including the number of buildings that increase the load above the surface. There are still many people who explore groundwater sources as the principal source of clean water. Also, the soil type is dominated by alluvial. This alluvial deposit can be one of the parameters for soil deformation in the form of land subsidence and uplift in land surface because basically, alluvial soil types have a susceptibility to the load support power above. So that the land subsidence in DKI Jakarta is relatively continuous. To find out the land subsidence is used a high-tech method, Differential Interferometry Synthetic Aperture Radar (DInSAR) satellite image of radar data (SAR Sentinel-1A) in 2017. The result shows the land subsidence in the average value of DKI Jakarta which is about -3.685 cm/year and the highest subsidence happened in the West Jakarta district about -5.850 cm/year in average.

Food waste can be meat, fish, cooked food scraps, moldy bread, bone scraps, cakes, expired foods, dairy products, fruits and vegetables. Food waste which is put into the trash will decay and produce a foul odor which in turn will invite flies and cause potentially diseases. Most of the food waste that is processed using the composting process needs to spend a relatively long time, which is about 1-3 months or even 6-12 months. This study aims to accelerate composting time through the addition of additive microorganisms in various quantities. Four aerobic composter reactors were utilized in this study. Variations of additive microorganisms added to the research object were 0 in reactor (control), 8 g in B2 reactor, 16 g in B3 reactor, and 32 g in B4 reactor. All reactors were added with dolomite lime. During the composting process temperature, pH, water content and macroelement were tested. The results showed that the mature and stable compost was reached on the seventh day and produced from B2 reactor. In That reactor treated food waste and additive microorganisms with a ratio of 7:3, and 1 g dolomite lime. The level of C/N ratio produced from B2 reactor was 16.71. The value of C/N ratio was better than B3 reactor which produced C/N of 18.37. The control reactor produced a C/N ratio of 21.84 and mature and stable compost was reached on the 14th day. All in all, this study was regarded to be successful in accelerating the degradation of food waste into mature and stable compost in just seven days.

In response to growing importance of household waste management issue, this article deals with the positioning of household waste transfer points from a government-organized waste perspective. By taking Surakarta, a municipality in Central Java, Indonesia as an example, the problem in the municipality is formulated as an MILP, is approached with a capacity-weighted set covering method, and finally is solved by using software LINGO 11. The article concludes that the transfer point alternatives of Sondakan Kuburan, Norowangsan, SPSA, Pajang Rel, Bonoloyo and Kedung Tungkul should be selected in order to be able to serve all the household waste producers for the maximum household waste generated. On the contrary, the selection of Sondakan Kuburan, Bonoloyo and Kedung Tungkul only should be able to provide service to all of the household waste produced for the scenario of minimum amount of household waste.

Environmental sustainability influenced social and economy sustainability. Without sustainably productive environment to provide resource foundation, it would difficult having sustainable society. Sustainable economy depends on sustainable raw material, energy and environmental resources. This work discussed about environmental sustainability in marine especially utilizing sea water as raw material for salt. This work started to investigate raw material characteristics and salt quality. The raw material characteristics represented high concentration for sodium, chloride, calcium and polluted by trace metal. According SEM-EDX result, salt contains lead and cooper. Salt farmer income is influenced by the salt quality, the higher its quality the bigger income received. Indirectly, economy in coastal was influenced by sea water quality. This is what encourages the research to achieve marine environmental sustainability in coastal area. The aims of this study are to review and categorize indicator for marine environmental sustainability into Driver-Pressure-States-Impacts-Response (DPSIR) and provide strategies suggestion for support environmental sustainability. DPSIR indicators are utilizing sea water, wastewater discharge into sea, increasing of sea water ion concentration, mangrove growth disruption, regulation for salt wastewater disposal direct to the sea. Recovery magnesium from salt wastewater is potential strategy to protect marine environment and to support economy-social sustainability.

PHE ONWJ is an upstream oil and gas company performing exploration and production of oil and gas. PHE ONWJ is subsidiary of Pertamina Hulu Energy (PHE) under PERTAMINA Group with working areas of 8.300 km2 covering offshore and onshore sites. As response to the declining of global oil price, PHE ONWJ is required to reduce its operating costs. One of them is marine operation that accounted for 10% of the total operating cost, 53% of which is the cost of energy (fuel). The marine fuel efficiency program is a technology based on approach through series of interconnecting activities namely determination of vessels’ economical speed, vessel control by Fuel Monitoring System (FMS) and Vessel Tracking System (VTS), and improvement of contractor performance management. This program has saved diesel fuel consumption for approximately 10,000 kiloliter or equivalent to savings by 34%. Financially it has saved Rp 80 billion and reduce emission by 40 ktons of CO2e during the year 2016. The keys of success of this program are strong commitment to implement economical speed, contractor partnership, capacity building and awareness to raise contractor’s competence also behaviour towards energy efficiency.
PHE ONWJ是一家从事油气勘探和生产的上游石油和天然气公司。PHE ONWJ是Pertamina集团旗下Pertamina Hulu Energy（PHE）的子公司，其工作面积为8.300平方公里，涵盖海上和陆上现场。为了应对全球油价的下跌，PHE ONWJ被要求降低运营成本。其中之一是海洋作业，占总作业成本的10%，其中53%是能源（燃料）成本。船用燃油效率计划是一种基于一系列互连活动的方法的技术，即确定船舶的经济速度、通过燃油监测系统（FMS）和船舶跟踪系统（VTS）控制船舶以及改进承包商绩效管理。该计划节省了约10000千升的柴油燃料消耗，相当于节省了34%。在财政上，它节省了800亿印尼盾，并在2016年减少了4000万吨二氧化碳排放量。该计划成功的关键是坚定地致力于实施经济速度、承包商合作伙伴关系、能力建设和提高承包商能力的意识以及提高能效的行为。
