Purpose of the study: Hazardous solid medical waste, contains infectious, pathologic, sharp objects, pharmaceuticals, cytotoxic, chemical, radioactive, pressurized containers, and has a high heavy metal content and endangering the community. The Minister of Environment and Forestry of the Republic of Indonesia No.56 of 2015 regulates hazardous waste, but the study of the implementation and compliance with the regulation are still limited. Methodology: Qualitative descriptive method is carried out to describe and explain the condition of variables contained in the object of research. Main Findings: In general, the health center in Depok has carried out sorting consisting of sharp medical waste and non-sharp and reduced hazardous waste. The composition of non-sharp hazardous medical waste ranges from 55% to 96%. Applications of this study: Primary data collection was carried out in 11 Health Center in 11 sub-districts of Depok City. Novelty/Originality of this study: The number of sub...

Document is a written letter that can be used as evidence of information. Plagiarism is a deliberate or unintentional act of obtaining or attempting to obtain credit or value for a scientific work, citing some or all of the scientific work of another party acknowledged as a scientific work without stating the source properly and adequately. Latent Semantic Indexing method serves to find text that has the same text against from a document. The algorithm used is TF/IDF Algorithm that is the result of multiplication of TF value with IDF for a term in document while Vector Space Model (VSM) is method to see the level of closeness or similarity of word by way of weighting term.  

Urbanization triggers an increase in urban land conversion. Along with the increasing population and the increasing needs of the shelter, people tend to use the remaining space such as riverbanks and river bodies which are not intended for residential buildings. This has a negative impact on the environmental and river ecosystems, as well as causing the changes in the function of rivers in urban areas, one of it is Ciliwung River which runs through Kampung Pulo. The government seeks to deal with the environmental damage on the riverbank through a revitalization program. This research was conducted to find out the impact of revitalization process by observing biophysical condition of river before and after eviction of people that live in the Ciliwung riverbank and provide a landscape plan of Kampung Pulo segment. Using secondary data of rainfall, land use, land cover and flooded area. The mapping with ArcGIS 10.1 shows there decrease in the area of flood puddle in Kampung Pulo.  

This study aims to identify and analyze the farmers’ perception of the climate variability and the impacts of the climate variability, identify and analyze the vulnerability and the income of the farmers due to the climate variability, identify and analyze the farmer strategy in anticipating and adapting the climate variability and recommending the adaptation mechanism based on engineering, institutional, technological, social, economic, and cultural organizations to the farmer in responding to the climate variability. Most of the farmers know and understand the climate change information from the television. Farmers mostly feel this climate change through the increase in temperature and the number of dry days. The impact of the climate change affects the livelihood of the farmers, not a few farmers suffered the losses due to the decreased in productivity. To reduce the decrease in income, the farmers increase the use of input, thus affecting the income of the farmers. The results o...

The palm oil industry produces greenhouse gas emissions such as carbon dioxide (CO2), methane (CH4), nitrous oxide(N2O) and other gases through the processing, transportation of vehicles and waste produced. Greenhouse gas emissions can be calculated by the Intergovernmental Panel On Climate Change (IPCC) method. The biggest emission source in the palm oil mill(POM) industry comes from Palm Oil Mill Effluent (POME) and can be reduced by capturing the methane. By making an estimation of greenhouse gases (GHGs) from the operation of the methane capture installation, the total emissions reduced that produced will be known. The palm oil mills that analyzed was a palm oil mill located in Belitung Island, Indonesia. The purpose of this study was to estimate the GHGs emission reduction from the palm oil mill after the installation of biogas methane capture facility. Using IPCC method, the total actual emissions reduction is 70,6%, and without addition of sludge removal in the reactor, the r...

Palm oil processing in palm oil mill produce solid and liquid waste. The liquid waste comesfrom the sterilization and clarification process, that are often called as Palm Oil Mill Effluent (POME).POME produce methane gas emissions that prompt climate change. Even though it releases a methanegas and has high Chemical Oxygen Demand (COD) content, POME has the potential to be a source ofenergy for biogas power plants. Then it utilized to produce electricity and supply the needs in factoriesor surrounding areas. This utilization also resulted in reduction of greenhouse gas emissions(specifically those resulted from the release of methane by POME). The purpose of this study was todetermine the amount of emissions produced from palm oil mills in the process of degradation ofresidual waste production. This study also aims to determine the economic value of electricity producedby the biogas power plant. Company`s calculation standard contrasted with IPCC calculation to gaugethe amount of em...

Purpose of the study: The purpose of this research is to analyze the characteristics of urban communities in the disaster response area to tackle floods. Methodology: In principle, this study uses an approach based on qualitative research. The area that is the background of this study includes the Cawang Village area which is prone to flooding. Sources of data in this study were interviewees who were community leaders who had lived for more than 20 years and local RT/RW devices. Main Findings: From the results of the research obtained, based on the experience of the residents, two of the largest outflows of capital were obtained, namely social capital and human capital, while the least capital outflows were natural capital. Applications of this study: The characteristics of urban communities in the disaster response area are kelurahan cawang, East Jakarta, and dki Jakarta. Novelty/Originality of this study: There are 2 capital components of SLA which are human capital and social cap...

Purpose of the study: The purpose of this study is to present a description and analysis related to the characteristics of the people exposed to disaster-prone areas, in villages (rural) and kelurahan (urban) levels, public awareness of efforts to "maintain" their survival from external disturbances, conformity to program interventions/activities carried out by external parties (government / non-government). Methodology: In principle, this study uses an approach based on qualitative research. Main Findings: From the results of the research obtained based on the experience of the residents, two of the largest outflows of capital were obtained, namely social capital and human capital, while the least capital outflows were natural capital. Applications of this study: This research will be carried out in the rural area with the threat of landslides in Cijeruk Village, Bogor Regency. Novelty/Originality of this study: Sustainable Livelihood Assessment (SLA), the higher the freq...

Lake Toba is one of ten programs the Ministry of Tourism in the Republic Indonesia, as a priority tourism area because of its unique potential. The Ambarita is one of 16 villages that are priority areas in Simanindo Subdistrict, Samosir Regency. At present, the quality of Lake Toba's waters has been polluted, the pollution is caused by domestic waste water which is discharged directly without prior treatment. The purpose of this study is to plan a domestic wastewater pipeline network and recommendations for wastewater treatment plants with a centralized system in the Ambarita. This study uses a data analysis method by using a population projection approach with maximum capacity to be planned in the draft MasterPlan of Ambarita and literature study for WWTP technology recommendations. The results showed that the total discharge of wastewater in the Ambarita was 0,06495 m3/second and the results of laboratory tests showed the parameters that exceeded quality standard were free chl...
