Abstract
Climate change can have an adverse impact on rice farming, so farmers might have to apply adaptation practices to address the impact. This research aimed to determine rice farmers’ adaptation practices in response to their perceived changes in climate. The study was conducted in Cialam Jaya Village, Konda Sub-district, South Konawe District, Southeast Sulawesi. Data were collected using questionnaire-based interviews and Focus Group Discussions. Respondents consisted of sixty-seven rice farmers who were selected using simple random sampling method. Descriptive statistics were used to analyze the data and information. Study results showed that most of the farmers had implemented adaptation practices as a response to climate change. Farmers have implemented adaptation methods in planting date, rice planting, improved seed varieties, fertilizer application, water management, crop diversification, livestock raising, and off-farm activities. The study recommended that suitable adaptation strategies need to be identified and the new ones need to be developed, and farmers should be assisted in their implementation to improve rice farming’s productivity and competitiveness.

Published: April 2021

Abstract
Indonesia has the potential of forest resources with an area of 120.7 million hectares. The government has established various forest area management mechanisms to create livelihoods, environmental services, and climate change mitigation efforts. This study aims to determine the contribution of village forests to the creation of livelihoods for the community through physical observation, social observation, and in-depth interviews. The Village Forest in the study location has advantages because it consists of terrestrial and aquatic ecosystems, so the biodiversity richness is very high. The strength of the village forest system is that it can be managed by local communities as a source of livelihood for 59.9% of respondents, but it is not yet optimal in its management as a source of income with the majority of respondents earning less than one million rupiahs (70% of respondents). Although, the majority of the 148 respondents (37.4%) are considered that the forest areas contributed to new types of work as a source of income. The potential for exploitation and degradation of forest areas needs to be considered because of the high frequency of people entering forest areas and opening access. The existence of village forests in the region directly or indirectly contributes to efforts to mitigate global climate change. It can be conserved and protected as a carbon pool and a carbon sink. The existence of various types of new jobs and potential economic opportunities from this can reduce the rate of forest conversion and exploitation by the community which is generally done to earn income.

Abstract
Climate change can cause sea level rise and the expansion of rice fields affected by intrusion or seawater runoff. This problem is the adaptation of rice varieties that are tolerant of fresh or sea waterlogged in the farmers’ land. The location of the activities was in Brangsong Sub-Regency, Kendal Regency, Central Java, in 2018. A split-plot factorial experiment was designed with 3 factors, variety of paddy, ameliorants, waterlogged height. This study’s data analysis techniques are analysis of variance followed by standard real difference analysis and descriptive analysis. The observations of ubinan (rice harvesting tool) showed that Inpari 30 had the highest harvested dry grain productivity of 10 tons/ha in humic acid treatment in a 5 cm puddle. Meanwhile, the recommended varieties of Inpari 34 and Inpari 35 did not produce high productivity due to the easily collapsed cropping. Inpari 34 has a high percentage of filled grain, namely 90%.

Abstract
The massive use of plastic, from the production process to the disposal, will release a lot of greenhouse gas emissions into the atmosphere, which will exacerbate climate change. The large amount of plastic waste that can not be decomposed and eventually carried away into the sea is estimated to cause more plastic than fish in the ocean in 2050. Indonesia is the second-largest country in the production of marine plastic debris in the world after China. It occurs because of a misleading in waste management while still on land. Plastic debris in the marine will adversely affect the ecosystem in the sea and also the coastal. The reduction of marine debris will not run optimally if it is not supported by active involvement from the government, producers, and the community. This research was normative research based on primary and secondary legal materials. This study aimed to review the implementation of policies based on action plans to reduce marine debris. The result showed that with the baseline marine debris policy at 0.49 - 0.86 million tonnes/year, it required acceleration efforts from the government, producers, and the community to reduce marine debris by 70% by 2025.

Abstract
Coastal areas are vulnerable to change because, in this region, many human activities and natural influences change. These activities can result in changes in the existing coastline. Moreover, the city of Surabaya has a reasonably long coastline. This study calculated the speed of shoreline change using remote sensing technology of SPOT 6 and SPOT 7 high- resolution satellite imagery from 2015 to 2019. Calculation of shoreline change speed is assisted by the application of the Digital Shoreline Analysis System (DSAS) using several methods, namely Shoreline Change Envelope (SCE), Net Shoreline Movement (NSM), End Point Rate (EPR), and Linear Regression Rate (LRR). Based on data processing and analysis, the longest coastline of Surabaya City was found in 2015 with a length of 69.605 km, and the shortest coastline was in 2019 with a length of 65.759 km. The maximum speed of Surabaya shoreline changes can be identified by using the SCE method (956.590 m), the NSM method (+584.722 m), the EPR (+148.725 m per year), and the LRR (+154.386 m per year). Also, an analysis of land area changes during the 20152019 period resulted in the Kalisari Village experiencing the most significant accretion of 358073.62 m2, while in Keputih Village abrasion of 30189.72 m2.

Published: April 2021

Abstract
Land subsidence can be caused by many factors, from natural through anthropogenic processes. Land subsidence due to anthropogenic factors results from such as fluid withdrawal, like oil and gas extraction. Cepu block is one of the oil and gas extraction areas that become Indonesia’s largest oil producer. This paper employs the Permanent Scatterers Interferometry Synthetic Aperture Radar (PS-InSAR) with C-Band Sentinel-1A imagery data to monitor the land subsidence phenomena. The PS-InSAR method is chosen because it can measure small movements in an area over time with millimeters DEM accuracy. The processing result showed deformation in the form of land subsidence in almost all of the blocks, except for Block D, with the mean velocity ranging from -27,75 to -9,78 mm/yr. An uplift phenomenon is also achieved in the eastern part of Block E. These PS-InSAR results are in the form of Line Of Sight (LOS). This paper correlates the land subsidence with geological maps to better understand the phenomena’ causes.

Published: April 2021

Abstract
In the past, geoid was computed from gravity anomaly data using Stokes or Molodensky approaches. Obtaining gravity anomaly data is difficult because it needs some reductions of gravity from surface of the earth to the geoid using orthometric height from spirit level measurement. In the modern era, gravity anomaly data may be replaced by gravity disturbance data. It only required gravity and GNSS (Global Navigation Satellite System) measurement. This research aimed to determine geoid using Hotine’s approach. Disturbance data were generated from archived free air anomaly of airborne gravimetry in Sulawesi area. South East Sulawesi province was selected as a case study area. In this study, gravity observation was calculated at an altitude of 4000 m above the reference ellipsoid. Gravity estimation at the same height aims to increase the precision of the downward continuation process to the geoid. Hotine integral is calculated above the geoid, so that the gravity disturbance data is downwarded to the geoid. The geoid undulation is graded from north to south. Geoid from airborne gravity around Pegunugan Mekongga in the northern part of Southeast Sulawesi Province has the largest geoid undulation which reaches 63 m, while the geoid in the southern part of Buton Island reaches 52 m. Geoid validation of airborne gravity at 13 test points produces a standard deviation of ± 0.050 m. The standard deviation is much smaller than the results of geoid testing from airborne data in North Sulawesi, Central Sulawesi and Southeast Sulawesi. This fact indicates that the Hotine approach has the potential to produce a precise geoid if used in geoid-based airborne gravity calculations.
Remote sensing of droplet number concentration of aerosol-induced clouds during the 2019 fire event in Borneo, Indonesia
Authors: Krisna T C , Hayati N , Hariyanto T 
Published: April 2021

Abstract
The droplet number concentration of liquid water clouds N is estimated based on the optical thickness τ and particle effective radius reff retrieved from the measurements of the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard of Terra satellite. Two measurements of MODIS taken from 15 June 2019 (case A) and 15 September 2019 (case B) are analyzed. They represent a condition before and during the 2019 fire event in Borneo, Indonesia. The result shows, that the domains of τ and reff are comparable for the two cases. While there is no sign of systematic bias in case of τ, the analysis of r eff tells differently. Clouds with smaller droplets, less than 12 µ m, are more prominent in case B, indicating the present of aerosol-induced clouds. In case A, the frequency distributions of clouds with larger droplets, more than 12 µ m, are systematically higher. The magnitudes of N in case A are mostly less than 100 cm-3, which exhibit a background condition. Extreme magnitudes of N, from 200 to 800 cm −3, are found in case B. Those excessive numbers are attributed to the region where the aerosol-induced clouds are observed.
