Palm oil as an agricultural commodity plays an important role in the development of the Indonesian economy, considering it in producing vegetable oil. Policies for developing new and renewable energy in Indonesia aims to encourage the optimization of the use of biofuels from oil palm. This policy still raises pros and cons, so that analysis needs to be carried out through an environmental science perspective. This study aims to assess the sustainability of palm oil (CPO) as a basic material for making biodiesel from environmental, social, and economic aspects, as well as to provide recommendations on a sustainable palm oil biodiesel policy strategy. The method used is a qualitative analysis. Descriptive analysis of supporting literature is used to assess environmental, social, and economic aspects of palm oil-based biodiesel sustainability in Indonesia. The use of biodiesel in the country is expected to be sustainable in line with the stipulation of the mandatory biodiesel of 30 percent (B30) in 2019 by the Government as a substitute for fuel mixture. It was found that there are advantages to using palm oil-based biodiesel compared to other vegetable oils. Palm oil-based biodiesel can be produced in a sustainable manner.
Dampak aktivitas di dalam Daerah Aliran Sungai (DAS), baik alami maupun karena pera nmanusia salah satunya adalah erosi. Erosi berkaitan dengan pengelolaan sumberdaya alam yang melibatkan aspek sosial, ekonomi, dan lingkungan. Perubahan iklim global, meningkatnya jumlah penduduk, dan intensitas kegiatan ekonomi mempercepat perubahan kondisi DAS, termasuk di bagian hulu. Sub DAS Lesti sebagai salah satu Sub DAS di Hulu DAS Brantas berperanan penting dalam menyumbang sedimen sebagai dampak erosi yang tidak terkendali,sehingga berpengaruh terhadap umur guna Waduk Sengguruh di hilirnya. Penelitian terkait erosi di Sub DAS Lesti selama ini hanya dikaitkan dengan faktor-faktor biofisik DAS seperti kemiringan lereng, faktor vegetasi, dan erodibilitas tanah. Keterkaitan aspek sosial, yaitu perilaku masyaraka tterhadap pilihan penggunaan lahan dan besarnya erosivitas limpasan adalah hal yang jarang dilakukan. Penelitian ini bertujuan untuk mengkaji keterkaitan ini dengan pendekatan statistik, hidrologi, dan spasial dalam kerangka ilmu lingkungan. Metode yang digunakan adalah mixed method dengan analisis perilaku menggunakan cross tabulation, debit limpasan dihitung dengan persamaan rasional modifikasi dan erosivitas limpasan dianalisis menggunakan rumus Williams (1975) serta tools SIG. Hasil overlay peta erosivitas limpasan permukaan dengan peta perilaku dan tata guna lahan menunjukkan semakin negatif perilaku masyarakat pada suatu kecamatan, maka semakin tinggi nilai erosivitas limpasan dan berada pada lahan yang rentan erosi.
Climate hazards that affect drought could have an impact on agricultural production. Cirebon Regency as one of West Java's food supply areahas experienced hydrological drought because ofclimate variability. Hence, there were many rice fieldswhich lack of water sources for irrigation and resulted in crop failure. Accordingly, this study aims to explore the historical and projection of drought periods as well as the severity of droughts in Cirebon Regency, Indonesia. Interpretation of weather and climate data and Standardized Precipitation Index (SPI) were employed for methods of this studyby using rainfall data only. Based on baseline data (1986-2017) from Jatiwangi Meteorological Stationand Global Circulation Model (GCM) projection simulation (2020-2045) under the Representative Concentration Pathways (RCP) 4.5 scenario, the SPI analysis results show that the drought periodsare predicted to shift in the future with increasing drought severity. This study concludes that climate variability that affects future dry rainfall will still happen in uncertain month periods.Therefore, climatic information is needed in the vulnerable area to reduce the potential impactsthat will occur in the future.
Many companies globally apply ISO 14001 including in Indonesia. In there, most of the implementers are largely established companies in terms of quality, financial, infrastructure documentation, knowledge and understanding of the ISO. ISO 14001 was issued in 2015 to replace ISO 14001: 2004 and consider a risk-based approach in its application. This research examines the SMEs laundry machine industry in Yogyakarta that attempts to implement and achieve ISO 14001: 2015 certificate. Research results inform the implementation of ISO 14001: 2015 in the SMEs industry to achieved the extended result and applied the risk-based approach. The description of every step is expected to give understanding and model for implementing ISO 14001:2015 in this case study location. This study finds out that SMEs can be effective in some of the clauses of ISO 14001:2015. With implementation ISO 14001:2015 in SMEs expected to change the environment for better, especially in reducing the impact of the waste produced where the waste contributes to the formation of greenhouse gases which means accelerating the occurrence of global climate change.
The reduced age function of Sengguruh Dam/Reservoir due to erosion in the upper of Brantas Watershed (Lesti Subwatershed area) interferes with its role in flood control, irrigation water supply and the supply of most of the hydroelectricity in East Java Province, Indonesia. This study aims to estimate erosion, analyze the interrelationship of the causative factors and provides environmental conservation direction. The research method uses mixed methods. The quantitative method of erosion rates is done by calculating the Modify Universal Soil Loss Equation which is supported by GIS tools. The qualitative method is carried out with questionnaires and interviews in the Lesti Subwatershed area. The results showed that the current erosion rate in each ha of land (average) in the Lesti Subwatershed was 153,868 tons / ha / year (exceeding the tolerable erosion rate of 30 tons / ha / year). The rate of erosion in the Lesti Subwatershed has always increased in the last 14 years. Of the 12 Subdistricts in the Lesti watershed, as many as 6 Subdistricts are identified as having high levels of Erosion Hazards so that they were a priority to be handled, namely in the Wajak, Dampit, Tirtoyudo, , Gedangan, Sumbermanjing Wetan and Bantur Subdistricts. Dampit Subdistrict, Turen Subdistrict and Gondanglegi Subdistrict also face behavioral problems and high population pressure compared to other Subdistricts. Research also shows that there is a relationship between erosion and knowledge, attitudes and behavior of the community in the form of population pressure and land use patterns. It is recommended that environmental conservation directives focus on these 6 Sub-districts through the application of soil and water conservation. The results of spatial analysis at priority locations suggest conservation measures in the form of law enforcement or counseling, and community empowerment to increase the ability and independence of the community through providing access to resources, education, and training.
West Papua’s tropical forests are one of the mega biodiversity in the Sahul Shelf ecoregion. The increasing economic growth has a déterrent impact on deforestation and forest degradation with the rate increased by 1.29% per year (2010-2018). Meanwhile, economic growth in Gross Regional Domestic Product (GRDP) reached 4.87% per year. This study aims to simulate carbon management from the forestry sector in West Papua into the long-term low-carbon sustainable development. This research uses a dynamic system method through Stock Flow Diagram (SDF) stage and model validation. The results showed that the forestry GRDP and emission based on the CM1 and CM2 scenarios calculated using emission reduction of 69.61% and 91.04% were determined by 0.28 and 0.09 times from BAU. The total GRDP and forestry GRDP decreased by 5.19% (CM1) and 6.59% (CM2) and 71.57% (CM1) and 90.93% (CM2). Under this scenario, West Papua could maintain a forest cover of more than 85%. The study concludes that the results of the BAU scenario predict forest cover of 70% in 2030. Simulations carried out with CM1 and CM2 reduction in emissions show that the achievement of forestry GRDP, total GRDP, and emissions is lower than BAU.
Mangrove forests in the northern coastal region of Karangsong Village, Indramayu Regency, West Java, form a crucial component of the livelihoods of coastal communities. The objective of this research is to know the diversity of species and mangrove vegetation based on growth level. The research method is explorative survey technique method. The data collection for the research vegetation data from 10 plots divided from observed tracks. This study resulted in the observation 9 species of plants: Avicennia marina, Avicennia alba, Rhizophora mucronata, Rhizophora stylosa, Rhizophora apiculata, Terminalia catappa, Casuarina equisetifolia, Ziziphus mauritiana, and Thespesia populnea. From the analysis, it is known Rhizopora mucronata are the dominant species in the Karangsong Village Mangrove Ecotourism area within three growth phases (seedling, sapling, and mature), which evidenced from the frequency of their presence in 7 (seven) sample plots. Based on the analysis of data obtained, the index of diversity (H’) of vegetation in mangroves and coastal of study area is 1.75, which means that this area has medium vegetation diversity. The calculated Dominancy Index for Karangsong Village Mangrove Ecotourism area is 0.210, which indicates that mangrove species has scattered growth pattern, thus means moderately high in diversity.
