Authors: Zulhusni Zakaria Mohammad , Mohamed Maryati 
Published: August 2019

Abstract
Biotic indices are very useful tools as a rapid water assessment since freshwater had became a global issues for a decade but most of biotic indices developed are based on data from Europe or North American region. Geographically, there might be different in term of composition of macroinvertebrates in tropical region. Moreover, lacking in information regarding the effectiveness techniques which limited the use of biologicl monitoring in developing countries. Study were conducted to compared between biotic indices that originately developed based on macroinvertebrate data from United Kingdom which is Biological Monitoring Warking Party (BMWP)) and several biotic indices which developed in tropical region which were BMWP-Thai, SingScore and BMWP-My. The purpose of this study is to know which index best reflects health of freshwater ecosystem in Malaysia. All indices were calculated based on data from Hutan Lipur Sungai Bantang (HLSB). HLSB ecosystem were provided a good physical and chemical variable which their water quality is ranging from moderately- good to excellent based on the composition of aquatic insects and water quality index (WQI). Despite of rapid development happened in Johor, we found 45 families of aquatic insects and half of them are clean water species and very useful in biological monitoring. From the result, BMWP-My was the most suitable biotic index to use in Malaysia water body since its give better reflect on the health of the river system. Finally, the uses of aquatic as biological monitoring tools were recommended because aquatic insects found almost in every freshwater habitat, their diversity and their sensitivity to environmental changes which make them a good biological indicator.

Abstract
Bada is the local name for Rasbora spp in Lake Maninjau. This fish is an economic fisheries commodity for consumption and has become one of the culinary icons of Maninjau area. Many studies have been carried out related to bada fish in Lake Maninjau, but continuous studies are needed to complete aspects that have not been done or for evaluation purposes, in order to take conservation or management actions. Therefore this study aims to convey the latest status of fish (species distribution of bada fish) and fisheries of bada (fishing activity, relative abundance distribution, and production trend). For species distribution of bada, sampling was carried out in six sampling station of lake waters (Bayur, Kularian, Muara Tanjung, Muko-muko, Sigiran, and Galapung) and four stream waters (Kularian Stream, Muara Tanjung Stream, Koto Gadang Stream, and a stream in Galapung) as inlets of Lake Maninjau in April 2017. For fisheries of bada analysis sampling was carried out in four stations of lake waters (Bayur, Linggai, Sigiran, and Galapung) from April to November 2017. Fish was caught using gillnet and liftnet. Catch data also obtained from some of fishermen as enumerator. In addition, interviews were also conducted with stakeholder from policy maker element. Species of bada were determined based on morphological identification. Three species of bada fish (Rasbora spp) were found in the lake and inlets of the lake, namely Rasbora lateristriata, Rasbora argyrotaenia, and Rasbora cf sumatrana. Rasbora lateristriata has the widest distribution in both lake and inlets. Analysis of Variance result showed that the abundance of bada fish (all types of Rasbora) was relatively same in all locations in Lake Maninjau (p > 0.05). Catch of bada in recent years declined sharply compared to 2008, for example catches in Bayur decreased by 80%. Current fishing activities also experienced a decline as fishermen using gillnet were rarely found. Current fishing of bada are mostly using lukah (trap) which were found in two locations, namely Rangeh stream and Batang stream. Bagan (lifnet) were found in Bayur, Muara Tanjung, Muko-muko, and Sigiran. Recommended management efforts are regulation of fishing (types of fishing gears and locations), maintain the lake and inlets connectivity, habitat improvement through construct fish shelters, and restocking.

Abstract
River becomes eminently threatened ecosystem compared to other aquatic environments. Contamination of the aquatic environment that come from anthropogenic activities, may reduce water quality and harm living creatures which is inhabiting within. The Cikamal and Cirengganis rivers at Pananjung Pangandaran Nature Reserve play an important role as water resources for local inhabitants around the nature reserve This research aimed to compare cytotoxicity and genotoxicity of Cikamal and Cirengganis rivers based on mitotic index (MI) and type of chromosomal aberration using Allium cepa as a biomarker. The methods used in this experiment were Completely Randomized Design and observation. MI analyzed using analysis of variance (ANOVA), followed by Duncan’s test. Types of chromosome aberrations were observed descriptively. The results showed that MI was declined throughout upstream to downstream on both river, as follow: upstream (Cikamal 62.4%; Cirengganis 62.1%), midstream (Cikamal 47.8%; Cirengganis 54,6%), and downstream (Cikamal 38.8%; Cirengganis 34.1%). The number of chromosome aberration types observed were 27 on Cikamal and 10 on Rengganis. The result suggested that Cikamal river has a higher cytotoxicity and genotoxicity level compared to Cirengganis. The Allium marker can serve as the first monitoring system for the presence of cytotoxic and genotoxic pollutant on aquatic environments.

Published: August 2019

Abstract
This study was carried out to analyze the effect of community behavior on water quality degradation in the Sekanak River. Both qualitative and quantitative research methods were used in this study. The quantitative research data was gathered by conducting a questioner survey of 100 selected households living along the riverbank to identify community behaviour. It was also used to measure the water quality status using Pollution Index (PI) Method. The descriptive qualitative component included analyzing and elaborating the actual data of community behavior toward water quality assessment using triangulation data sources. The questionnaire results of the research revealed that the household’s knowledge and attitude on disposal management, sanitation and hygiene at the river bank were in high level. They are generally knowledgeable, having positive attitude and also practiced good personal hygiene, but twenty percent was still throw the garbage to the river. Furthermore, a total of seven sampling station has been identified along the river. The result showed that water quality status from the upstream to the downstream had slightly polluted. It is also evident that COD, BOD, NH3-N and Phosphate have exceeded the allowable threshold levels. This may attributed to the anthropogenic activities such as washing and throwing garbage which can be indicated from changing in the levels of COD and phosphate. However, water pollution inevitably occurs due to the unavailability of communal wastewater treatment plant, poor waste management and lack of public stimulus such as incentive and punishment that encourage participation of communities to conserve water resource. Besides the technical aspect, Dealing with complex socio-ecological issues are considerable importance components of a long-term environmental strategy. It is recommended that education, legislation and incentivization are necessary to spur and improve people awareness and potential role as “river guards”.

Abstract
Ecovillage is one of the holistic solution to solve environmental problems, which the concept and theory of sustainability is practiced. Ecovillage is a concept where the community have to manage the environment properly and all the activities have a positive impact on the environment. In practice, the ecovillage should follow four aspects as follow: Ecology, Economy, Social and Spiritual aspect, on which of each this aspect are evaluated and analyzed. This research is different from the existing research because it will assess four sustainability aspects of the ecovillage. This research focused its research on the West Java Environmental Agency’s Ecovillage program in Bendungan Village, Bogor Regency, West Java, Indonesia. Ecovillage programs in this village are interesting to research because it is the first top-down ecovillage program in Indonesia and the world. This research used Mixed Methods approach (quantitative and qualitative), secondary data review, direct observation and semi semi- structured interviewing to collect the data. This research found that human and environmental aspects are equally important and needed to achieve sustainability, the environment cannot sustain if the human are oppressed (socially or economically) and vice versa. Lastly, it also shows that sustainability is a very complex term, sustainability studies need to include the interactions between natural and social systems and to achieve sustainability, a project or a program should include human aspects as part of the project or program as human are resources to achieve sustainable development and also the part of the development target alongside environmental aspects.

Published: August 2019

Abstract
The green revolution was able to make Indonesia a food self-sufficiency country in 1984, but on the other hand there were negative impacts caused by the green revolution such as the emergence of environmental and social and health problems. Organic farming is one solution to overcome the negative impacts caused by the green revolution. Public awareness of health and environmental care encourages people to adopt a “back to nature” lifestyle that is consuming organic food even though the price is more expensive. Such conditions open opportunities for the development of organic agriculture among farmers, including in the Nurani Sejahtera Farmers Group who cultivate organic rice using the SRI method. However, in recent years there has been a trend in the extent of certified organic land in the Nurani Sejahtera Farmers Group, which has decreased as well as the number of farmers. Therefore this study aims to explore internal and external factors that influence the development of organic rice in the Nurani Sejahtera Group, by using SWOT analysis. The results show that the strategy should be taken by the Nurani Sejahtera farmer group is Hold and Maintain strategy. It’s mean strategy that should be taken by farmer group is the survival and safeguard strategy through market penetration and product development. Market penetration strategy is searching for a larger market share or an increase in the market share of existing products or services through increased marketing efforts. and safeguarding, as well as market penetration through network development.

Abstract
Climate change mitigation policy has a strong influence on policy processes in worldwide. Indonesia as a developing country has committed to reducing greenhouse gas (GHG) emissions by 29 percent by the year 2030. This calls into question the extent of how the cities or local governments can cope with the challenges of the current transport sector climate change mitigation in Bandung City. This paper aims to assess the governance context of climate policies in Bandung City and support further co-benefits. The preliminary stage of study shows that the policies in reducing GHG emissions are not in accordance with what was written by the government. The provincial and local government was aware that the stipulation delivered by the central government regarding mitigation on climate change stated in the regulation both in provincial and local level. Based on the actor’s characteristic, the policies that encourage to reduce GHG emissions drive as a multi-actor interaction process namely The Paratransit, Trans Metro Bandung (TMB) and Vehicle Emissions Test. The research design involved an empirical case study on governance and policy relevant to climate change efforts to lower GHG in Bandung City, Indonesia. The analytical framework used for this analysis is the Governance Assessment Tool and the co-benefits approach. Data collection involved semi-structured interviews, a review of policy documents, and secondary quantitative data. The results reveal that the governance qualities create a context that there still are some limits, although several improvements have shown the positive trend at the local level. This is due to the qualities of the extent aspect as a low to moderate, the flexibility as a restrictive, and the coherence and intensity as moderate. The assessment of the criteria of co-benefits is more relevant to the public transport. The TMB has met all of the criteria of co-benefits. Thus, this TMB program has the highest impact to attain the co-benefits. The paratransit has the positive value of the criteria for lowering GHG emissions, energy and environmental sustainability, and development goals. The vehicle emission test met the criteria of sustainability and technical feasibility.

Abstract
El Nino 2015 has made a prolonged drought. This phenomenon has influenced the attitudes and perspectives of the people towards nature. This study aims to describe the change in natural management at the post-drought. El Nino causing the debit of five water springs decreased and dried. This condition trigered to conflicts of interest and ownership of the spring betwen Laluhe and Marampit Villages. The community rise its awareness to the importance of trees around the spring so that they tried to replant tress and to limit the use of natural resources and provide a village regulation in 2012 on the good governance of natural resources. In 2017, five other villages on Marampit Island agreed to support the efforts of tree planting and protection of springs done by Marampit villages. The Marampit community can be catagorized as a higher perspective and care of its nature resource than the others. In fact, the changing in natural resource management is more influenced by culture than other social factors. This social capital is an opportunity to improve environmental conditions to be more stable.

Published: August 2019

Abstract
Tempeh is a traditional soybean product originating from Indonesia. Tempeh is a high-protein food, which costs less per unit than other animal protein sources. However, the Tempeh industry will produce waste with this process. Tempeh production process requires a lot of water to boil, soak, and wash soybean skin. The research problem is that the practice of Tempeh industry has not managed wastewater well, which has the potential to cause the quality of tempeh industrial wastewater to exceed quality standards and cause negative impacts on the environment and society living around the industry, so alternatives are needed to improve wastewater management. The alternative is to convert liquid waste into renewable energy. It refers to the SDGs agenda for seven objectives (7) to improve clean energy research and technology, including renewable energy, energy efficiency, and sophisticated and clean fossil fuel technology. Biogas is a type of biofuel that comes from living things and renewable energy. This research aimed to determine the type of biogas that is appropriate for small-scale industries by utilizing Tempeh liquid waste with a mixture of household organic waste. The results showed that the biogas digester balloon is the type that is suitable for small scale industries. The selection of balloon digester is reviewed from the technical aspects, economic aspects, environmental aspects, and social aspects. Biogas is the right technology to convert tempeh waste into energy so that it can obtain economic and environmental benefits.

Abstract
Phytoremediation is Green Sustainable Technology for Industrial Waste Management, Oil sludge is a waste derived from the petroleum industry and includes hazardous and toxic substances that must be biologically managed. One of the efforts to overcome oil sludge waste is by using bioremediation. The toxicity from oil sludge derived from phytoremediation that has been done by using consortium bacteria (Bacillus sphaericus, Pseudomonas sp.) and mycorrhiza of Chinese albizia plant (Paraserianthes falcataria) for up to 14.5 months needs to be monitored and evaluated to female Wistar rat (Rattus norvegicus) as biological model. The purpose of this study was to obtain LD50 from oil sludge extract of phytoremediation and to determine its toxicity on rats based on histological observation. The laboratory experiment with complete random design method was conducted. Acute toxicity test was performed based on protocol from OECD 425 in 2008 with modification. The parameters observed consist of animals mortality, changes in body weight, and liver histological damage levels. Probit analysis showed that LD50 from oil sludge extract was 9,785.184 mg/kg bw which is categorized as slightly toxic. This value still did not meet the results of the bioremediation process (> 15.000 mg/kg bw or not toxic). Therefore, the oil sludge phytoremediation process needs to be improved until the required policy is fulfilled. This study provides information on the evaluation approach when bioremediation used as an alternative method to restore the oil-contaminated soil.

Abstract
Development of agricultural sector eternally involved the problem of uncertainty of the results and a considerable risk. The development of agro-tourism in Cirebon Regency will directly develop mango agribusiness. Increased interest in tourism creates opportunities for agricultural tourism development (agro-tourism). Mango demand is very high, making opportunities as well as challenges for mango farmers in Cirebon Regency. This study aims to consider risks in mango agribusiness, risk assessment and mitigation of mango agribusiness in the development of agro-tourism area in Cirebon Regency. Data collection was through observation, interview, documentation, and questionnaire. The method used is Failure Mode and Effect Analysis (FMEA). The method of FMEA identified risks that are classified into four categories: input risk, operational risk, environmental risk and financial risk. This type of research uses a qualitative approach, with primary and secondary data. The respondents were taken by purposive sampling. The research shows that the highest risk faced by actors in mango agribusiness in Cirebon Regency based on the highest risk of Risk Priority Number (RPN) and Risk Score Value (RSV) are pest and plant disease, uncertain weather, low productivity of farmers, high price of agro-input, excessive use of pesticides, and less skilled labor. Mitigation actions that can be done in reducing the effects of the risks are as follows: improving knowledge and training on Good Agriculture Practices (GAP), Good Handling Practices (GHP), Improving the role of government through extension agent, increasing knowledge of food safety, the creation of technology in agriculture from inputs, cultivation techniques, postharvest and marketing.
