Abstract:
One of the government programs to achieve the target of the National Waste Management Policy and Strategy is to build a regional landfill. To support regional landfill operations, the local governments which have utilized regional landfill need to prepare policies and strategies for optimizing waste management services in their area. Depok City is one of four cities that will served by Nambo Regional Landfill. The purpose of this study was to analyze various alternative policy scenarios to optimize waste management services in Depok City and determine their effects on the amount of waste transported to Nambo Regional Landfill. The policy analysis method used simulation model with a dynamic system approach. The simulation was conducted from 2020 to 2045. There were four scenarios, namely business as usual scenario, scenario A for the optimization of existing waste treatment facilities, scenario B which was based on local waste management policies and strategies, and scenario C for achieving 30% target of waste reduction. The simulation results showed the waste generation in 2045 was estimated to reach 3,426 tons/day. Results from all scenarios showed that the amount of waste disposed to landfill exceeds the maximum waste input to Nambo Regional Landfill. From scenario C, the amount of waste to be processed in the local landfill in 2045 was at least 1,180 tons/day. Depok City has a huge amount of waste and will continue to increase, so it is necessary to add waste treatment facilities and local landfill for the next 26 years. Landfill needs can be reduced by increasing waste treatment, but it requires greater waste management costs.

Abstract:
Urbanization and poverty are two important aspects closely linked to sustainable development goals. Urbanization in Indonesia is still far from improving migrant welfare as well as their destination regions. Every 1% growth of urbanization in Indonesia can only increase 4% of GDP per capita. Low economic benefits resulted from urbanization in Indonesia merely shift rural poor to become urban poor. The purpose of this study was to analyze the effect of urbanization on poverty reduction in Indonesia, both in the regional aggregate and at the rural and urban levels as the origin and destination regions of urbanization. This study used secondary data of population and poverty from Population Census (SP), the Inter-Census Population Survey (SUPAS), and the National Socio-Economic Survey (SUSENAS). Data analysis was performed using regionalization techniques, Primacy Index, Lorenz Curve, Geographic Information System (GIS), and simple linear regression. The results showed that the rate of urbanization had a positive relationship with per capita income and the population of urban poor, but had a negative relationship with the population of rural poor. A unit increase in urban population variable percentage would increase the average GDP/capita variable by 0,466. This would be followed by an increase in the average urban poor population variable by 0,447 and a reduction in the average rural poor population variable by 0,705.

Abstract:
The increase in salt consumption is not proportional to the growth of salt production land. So far, the mapping of salt ponds has been carried out on a small to medium scale, so the accuracy is not too good. This study aimed to analyze changes in large-scale salt ponds in Rembang Regency during the period of 2005-2015. The data source used is a Very High-Resolution Satellite Image (CSRST) which has been corrected and other secondary data. Salt area was calculated through visual interpretation and manual detection. CSRST data usage by visual interpretation methods and manual detection had advantages in terms of geometric accuracy compared with the use of medium-sized image of automation methods. The analysis showed that the area of salt land in Rembang Regency increased during 2005-2015. The biggest increase occurred in 2005-2011, which increased by 546,255 ha or by 32%. The increase in area during 2011-2015 was not significant by 198.45 ha (11.46%). Area expansion was expected to occur in the next few years, but it was not expected to be significant because of the optimal land use in the most of Rembang already. Expansion of salt ponds remained possible by converting the existing rice fields on the coast of Rembang Regency. However, a comparative study of the economic value of rice fields and salt ponds must be carried out before converting the paddy fields to salt ponds.

Abstract:
Northern Bandung Area (KBU) plays a vital role and function to surrounding areas as a groundwater catchment area. The West Java Province Spatial Plan (RTRW) stipulates KBU as the Provincial Strategic Area (KSP) for environmental protection. The spatial control governance over the KBU is currently regulated by the Governor Regulation Number 2 Year 2016 about Guidelines for Controling the Northern Bandung Area as the the West Java Province Strategic Area. The KBU development ought to take environmental carrying capacity into account concerning the completion of environmentally based spatial use programs in the KBU. This study aimed to analyze the environmental carrying capacity of land use, and to formulate program recommendation of desired spatial use in KBU. Conservation index method was used to analyze environmental carrying capacity necessary to spatial use program recommendation. The results showed that the land use coverage in 2015 decreased actual conservation function, creating an increase of critical conservation areas by 68.37% and by 69.78% in 2018. In contrast, the conservation index on the land use plan in the RTRW showed a decrease in critical conservation area to 35.90% in 2029. However, such a declining figure has not been supported by environmental programs in the land use plan implementation required to increase the good conservation class by 42.27% while it recorded by 10.78% in 2018. It can be concluded that the IKA and IKC studies showed a distribution expansion of critical lands in KBU, and the IKR analysis proved that the land use plan in the RTRW would reduce critical conservation areas.

Abstract:
Policymakers in the world are concerned with carbon emission due to the risk of global warming. Many studies on Environmental Kuznets Curve (EKC) consider carbon emission as a proxy of environmental degradation. This study aimed to investigate the existence of EKC and identify variations of relationships between carbon emissions and GDP per capita in ASEAN middle-income countries. The study was conducted on Indonesia, Thailand, Philippines, and Malaysia based on 1971-2014 time series data using a simultaneous model (2SLS) for each country. The main variables studied were GDP per capita, square of GDP per capita, and carbon emission supported by other variables as the controlling variables. Validation on EKC existence was determined by GDP and GDP squared influence on carbon emission, while variations of relationship between GDP and carbon emission were based on the result of simultaneous regressions. The results showed that the existence of the EKC could not be validated in all countries because energy and transportation policies in each country failed to reduce the emission. On the other hand, carbon emission had a positive unidirectional influence on GDP in all countries. The effect of carbon emission coefficient to GDP showed that Thailand ranked the highest in CO2 efficiency, followed by Indonesia, Philippines, and Malaysia. This study recommended that carbon emission reduction policies in the four countries should focus more to easier access to environmentally friendly technology from developed countries for ensuring trade-offs between the economy and environment.

Abstract:
Paddy farming has been affected by climate change phenomena such as high rainfall and long dry seasons which have caused plant and crop failure. To minimize the impact of climate change on their farming, paddy farmers undertake various strategies for dynamically adapting to climate change. This study aimed to analyze and assess the dynamics of the mitigation response by paddy farmers in West Java to minimize the impact of climate change. The object of research was paddy farmers in West Java. The research sample was selected using a multi-stage cluster random sampling technique to collect 300 respondents. Data analysis methods used descriptive statistics and multivariate analysis of variance (manova). The results showed that paddy farmers in West Java have dynamically mitigated climate change along with climate change over time. Types of climate change mitigation response applied by the majority of paddy farmers in West Java included planting shading trees, using energy saving technologies, cultivating organic agriculture, planting different crops instead of rice, changing farming to animal husbandry, migrating, looking for other income sources outside farming and renting/selling their land. Other mitigation responses that have rarely applied but interesting to explore were of shifting the planting and harvesting periods, selecting planting varieties, adapting plantation patterns and irrigation techniques. Farmers in Subang District who applied the most four types of climate change mitigation response earned higher income greater than those in Indramayu and Karawang.

Abstract:
Agriculture sector performs prominent role in the economy of Pinrang Regency. As the national food-estate area of South Sulawesi Province, RGDP agriculture sector of the regency increased from 4.72 to 7.94 trillion IDR in 2013-2017. This study aims to analyze food-crop agriculture land development based on primary commodities in Pinrang Regency, South Sulawesi. This study was conducted in twelve sub-districts in the regency’s area from September 2018 to June 2019. Application of geospatial technology was expected to present new approach with more accurate and easily updated land development planning in the area. The research data consisted of primary field survey data and secondary data of spatial pattern map of RTRW 2012-2032 from Bappeda and food-crop harvested area and production from BPS Pinrang Regency, characteristics and existing land use map from BBPPSDLP, and forest and water conservation area map from KLHK. Primary commodities was detemined based on Location Quotient and Shift Share Analysis. Potential land arrangement was referred to FAO Land Suitability Evaluation. Land development plan was formulated using selection and screening procedure based on Boolean logic. Five primary commodities was determined with 5,871 Ha potential land suitable for their development out of 7,324 Ha available land that consisted of land uses planned for paddy (3,529 Ha), cassava (1,398 Ha), corn (657 Ha), soybean (187 Ha), and sweet potato (100 Ha). The land development plan for these commodities was categorized into the first (147 Ha) and second (5,724 Ha) priority.

Abstract:
Between 2000 – 2017, 3.06 million hectares of primary forest in Kalimantan have been converted into palm oil plantation. This change impacts local climate changes. This study aims is to analyze the heat island in palm oil plantation. The analytical method used surface temperature estimation through remote sensing and zonal statistics. The remote sensing data that are used is Landsat 8 images acquired on 15 July 2018 and 3 August 2019. From this research, we found that young palm oil plantations have an average IHI value of 2.1 ± 1.7oC in 2018 and 1.7 ± 1.4oC in 2019. The IHI value is close to the heat island in a built-up area. IHI for mature palm oil plantation (11-12 years) created a cool island with an intensity close to secondary forest. The decreasing value of IHI for 2018 and 2019 in palm oil plantations is due to the growth of palm oil trees, which decreases surface temperature. The implication of this research is to know heat island effect due to deforestation or land cover changes, especially change into palm oil plantations.

Abstract:
Kumpulrejo Village becomes the priority of Salatiga City in the sustainable village development based on the local potential of agrotourism. Kumpulrejo holds potential in livestock farming, nearly 80% of the population are dairy farmers. Suboptimal institutional capacity of the Livestock Farmer Groups in managing potentials results in problems regarding sustainable village development program in Kumpulrejo. The community’s social capital is expected to significantly affect the Livestock Farmer Groups’s institutional capacity strengthening. The present study aims to find out the affect of social capital on the institutional capacity strengthening with regard to argoturism-based sustainable village development in Kumpulrejo. The method that used was quantitative-descriptive, data obtained from questionnaires, observation, and interview. The sampling technique used by simple random sampling, to the 60 respondents. The study showed that social capital which consist of a trust, social network, and norms significantly affect to the institutional capacity strengthening by 57,9%. Partially, a trust did not hold significantly affect, while social network and norms significantly affect the institutional capacity strengthening of livestock farmer groups in Kumpulrejo Village.
