Abstract
The Government of Indonesia committed to implement the Sustainable Development Goals (SDGs) aim to end poverty, inequality, and mitigate climate change. The submission of an Enhanced Nationally Defined Contribution (ENDC) to UNFCC strengthens Indonesia’s commitment in a low-carbon and climate-resilient economy development. The Minister of Finance has launched an ESG Framework to mainstreaming ESG through government support and facilities on infrastructure financing, in which IIGF (Indonesia Infrastructure Guarantee Fund) has a significant role in providing sovereign guarantee for Public-Private Partnership (PPP). Qualitative approach was used to examine the benefit of ESG and additional value of IIGF’s ESG integrated guarantee to support the acceleration of the Indonesia’s sustainable infrastructure development. This paper concludes that in addition to de-risking instrument, the guarantee will bring additional value in ensuring a fair ESG risk allocation, project structuring and long-term risk management and monitoring. This will allow privates to access green and sustainable financing. The challenges mainly on capacity building and alignment of policy and standards among stakeholders. However, IIGF has opportunity to link with stakeholders and build collaboration to fill gaps and connecting to suitable market. This paper, however, report initial findings of the ongoing comprehensive studies as part of IIGF ESG initiative roadmap.

Abstract
Indonesian forests are known to have high diversity and play an important role in human life, so they need to be managed sustainably. Sustainable forest management does not only pay attention to productivity aspects but also demands protection of Occupational Safety and Health (OSH). Remote sensing is used to provide information about hazard sources using geospatial data to analyze the level of risk of OSH interference in forest management activities at RPH Takokak, KPH Sukabumi. There are six hazard sources as parameters, namely slope, elevation, rainfall, type of soil, vegetation density, and accessibility, as well as the history of work accidents which are addressed to forest management stakeholders through the questionnaire method. From the five classification classes, it was found that the study location was dominated by class 3 classification or had a moderate level of risk of OSH interferences with an area of 1.661,02 ha or 77.36%, and an area of 0.49 ha or 0.02% included in risk class 4 or had a high level of risk of OSH interferences. The results and recommendations of this study are expected to provide information to Perum Perhutani in managing forest areas, especially risk management and can become a reference for further research.

Abstract
The deficiency of productive agricultural land was an obstacle to the development of mustard green cultivation. The utilization of acid-dry land is a solution for the development of mustard green cultivation. South Kalimantan has acid-dry land covering an area of 87.61% of the total dry land. The use of coffee grounds compost is an alternative technology for improving soil fertility in acid dry land. Coffee grounds compost can increase soil organic matter, so it can fertilize the soil and increase crop production. This study aims to determine the quality of coffee grounds compost and determine the best dosage of coffee grounds compost to increase soil pH, growth, and production of mustard greens in acid dry land. This research method used a single-factor randomized block design (RBD), namely the dose of coffee grounds compost: k0 = 0 t ha−1; k1 = 10 t ha−1; k2 = 20 t ha−1; and k3 = 30 t ha−1. The physical and chemical characteristics of coffee waste compost have met the criteria for quality compost based on SNI No. 19-7030-2004. The results showed the effect of coffee grounds compost on increasing soil pH, growth, and production of mustard greens. The best dose of coffee grounds compost in increasing soil pH, plant fresh weight, and mustard productivity was found in the K3 treatment with increases of 18.05%, 67.21%, and 67.21% respectively compared to the control. The best treatment for increasing plant height, number of leaves, and width of mustard leaves was treatment k1 with an increase of 51.34%, 31.03%, and 40.60% respectively compared to the control.
Determining the slip rate of the Kendeng Fault in East Java through GPS observations
Authors: Yuzariyadi M , Ramdani D , Syetiawan A , Susilo S 
Published: December 2023

Abstract
The Kendeng Fault is recognized as an extension of the Flores back-arc thrust, primarily exhibiting thrust fault behavior. However, prior research has indicated the presence of a significant right-lateral shear component along this fault. While no significant seismic events have been documented in recent years, historical records suggest that the region experienced significant seismic events prior to the 20th century, necessitating a careful consideration of the earthquake hazard associated with this fault. The question arises whether the absence of recent seismic activity is a consequence of energy accumulation or gradual energy release. Our investigation utilizes GPS data collected over a four-year period starting in 2016 to determine the slip rate of the Kendeng Fault. Our findings indicate that the slip rate along the Kendeng Fault is approximately 0.45 ± 0.07 cm/year. These results provide valuable insights into the behavior of the Kendeng Fault and contribute to a better understanding of its seismic potential and associated risks.

Abstract
The current condition of the Watershed (DAS) has undergone many changes from time to time. The opening of new land areas for agricultural, plantation, mining, residential and industrial activities often does not concern to the sustainability of nature, causing ecosystem changes. The study is aimed to analyze the availability of forest cover over the Merangin-Tembesi watershed and the critical index of the forest area existing. The existing forest cover was analyzed by conducting land cover classification using GIS software and groundtruth. The critical index was performed for the forest area in this watershed. The results showed that critical land in the Merangin Tembesi Watershed was divided into 5 classes, namely uncritical land class with an area of 823,294 ha (60.98%), potentially critical 88,552 ha (6.56%), moderately critical 360,792 ha (26.72%), critical area 52,669 ha (3.90%), and very critical 24,791 ha (1.84%). Protected Forests (HL) in Sarolangun Regency and Merangin Regency are dominated by the moderately critical class 75,260 ha (87.47%) followed by the non-critical class with an area of 5,828 ha (6.77%), critical potential class with an area of 2,189 ha (2.54%), critical class with an area of 1,582 ha (1.84%), very critical class 1,179 ha (1.37%).
Climate change influences global distribution of alien tube worms
Authors: Hadiyanto Hadiyanto 
Published: December 2023

Abstract
Alien tube worms have been introduced outside their original distribution areas via international shipping and have become invasive in these areas. Climate change has been acknowledged to redistribute both native and alien species; however, the effect of climate change on the global distribution of alien tube worms is unknown. This study predicts the global distribution patterns of alien tube worms (Hydroides elegans, Sabella spallanzanii, and Ficopomatus enigmaticus) and projects how climate change influences these patterns using species distribution modelling. Sea surface temperature, salinity, primary productivity, phosphate, nitrate, and current velocity are selected as the predictors. The models predict species occurrences well, with AUC values greater than 0.95. Under the present climate scenario, the occurrence probability of alien tube worms is high (>0.9) within the temperate Atlantic Ocean, Persian Gulf, Sea of Japan, Yellow Sea, Southern China, and Southern Australia. The probability of occurrence is expected to increase across oceans by 2100, suggesting that alien tube worms will be more common in the future. Increases in occurrence probability are also projected at higher latitudes (e.g., Barents Sea) by 2100, indicating poleward shifts of these species. This study highlights the urgency of incorporating climate change into the management of alien invasive species.

Published: December 2023

Abstract
On January 19, 2021, a flash flood hit the Upper Ciliwung watershed, a mountainous area in Indonesia, causing damage to seven buildings and displacing 1,800 residents. To minimize the impact of such disasters, there is a need for disaster risk awareness and management specifically focused on flash floods in mountainous regions. Therefore, this study aims to assess the flash flood potential index value in the Upper Ciliwung watershed. The research utilized deterministic (Soil and Water Assessment Tool-SWAT) and parametric (Flash Flood Potential Index-FFPI) modeling to analyze various factors, including slope, geology, ground movement, Antecedent Precipitation Index (API), and Runoff Coefficient (Curve Number-CN). The models showed satisfactory goodness-of-fit statistics with R2 and Nash-Sutcliffe efficiencies (NSE) values of 0.58 and 0.57, respectively. The findings indicated that 39.95% of the watershed had a moderate vulnerability index value of 3, while downstream areas (31.7%) had a low vulnerability index value of 2, and the middle and upstream regions had high vulnerability index values of 4 and 5, covering 23.65% and 2.49% of the total area. These results provide valuable insights to local authorities for implementing measures to reduce the Upper Ciliwung watershed’s vulnerability to flash floods.

Abstract
Differences in the impact of climate change are influenced by the level of vulnerability of each individual, including in terms of gender. Differences in access and control often make women more vulnerable to climate change than men, so the impact and adaptation to climate change will be different. This study aims to understand the differences in the impacts of climate change from a gender perspective in Lombok, West Nusa Tenggara. The quantitative and descriptive method uses data and information obtained from literature reviews, field surveys, and interviews. In addition, a vulnerability analysis was also carried out for the Lombok region using the Livelihood Vulnerability Index (LVI) assessment. The projection results show that Lombok will experience climate change, such as increasing air temperature and decreasing rainfall. Lombok’s vulnerability to climate change is in the LVI value range of 0.376 to 0.448. The impacts of climate change felt by men and women in Lombok differ because of differences in access, participation, control, and benefits (APCB) influenced. The results show that women are more vulnerable than men. One of the most influential factors is the lower education level for women due to limited resources and access, resulting in a need for more understanding regarding climate change.

Published: December 2023

Abstract
The resistance of sandy soil against liquefaction is influenced by its grain size and relative density. This study investigates the potential for liquefaction and settlement resulting from liquefaction. A single axis shaking table was employed, with a displacement of 2.5 cm and a box measuring 400 mm long, 400 mm wide and 600 mm height. Various relative soil densities were evaluated, namely 40%, 50%, 60%, and 70%, along with 1 Hz and 1.2 Hz seismic frequency variations. The experiment used three pore pressure transmitter sensors to measure the increase in pore water pressure (top, middle, and bottom), accelerometer sensors to measure acceleration, and settlement measurements at 12 points. The experimental findings prove a correlation between the relative density of the soil and its liquefaction potential. Increasing the relative density of the soil results in a decrease in settlement, ranging from a maximum settlement of 2.93 cm to a minimum settlement of 1.77 cm. Concerning the variation in earthquake frequencies, higher frequencies correspond to increased soil settlement, showing a difference of 15% to 33%. This study highlights the significance of earthquake frequencies and relative soil density in assessing the potential for soil liquefaction.

Abstract
The Geomorphic Flood Index (GFI) model can show flood inundation in a watershed based on flood events. Flood inundation can occur because of the backwater effect in the river channel. The different water levels from the river and tide that occur downstream may temporarily disturb the water depth and flow velocity. Because of this disturbance, a backwater effect might occur. The case study is located at the Plumbon River in Semarang City, which has the potential for a backwater effect in the river downstream. Backwater is a hydraulic phenomenon that occurs in rivers and can be simulated using a hydrodynamic model, as it can show the relationship between river discharge and tides. The conventional GFI method does not consider hydraulic effects, such as backwater effects, as part of the calculation. Therefore, modifications will be inserted into the calculation of the hydraulic effect on the modelling of flood inundation. The main purpose of this study is to build a modified GFI method that includes backwater analysis in its modelling to predict the backwater effect that occurs downstream of rivers and its impact on inundation. This study will help rapidly predict flood inundation.

Abstract
There are a number Green House Gas (GHG) emission guidelines for palm oil that are frequently used to determine annual GHG level for various purposes, one of which is to develop a mitigation strategy. The objective of the study was to evaluate three different GHG calculation guidelines (RSPO, ISCC, and GHG Protocol) for palm oil and implication on mitigation planning. The three different guidelines and their result on GHG calculation were observed by comparing data activities of emissions sources, emission factors, and cut-off date by using Life Cycle Assessment (LCA) approach and Intergoverment Panel Climate Change (IPCC) guidelines as references. The results of benchmark were then used to determine steps for a mitigation strategy. The result shows that utilization of cut-off date in GHG calculation from land-use aspect has a significant impact on GHG emission calculation result used for the development of mitigation strategy.

Published: December 2023

Abstract
Long-term intensive land management practice has been proven to decrease soil quality due to soil compaction. Theoretically, it would be easy to overcome by applying organic matter. However, conventional organic matter application in pineapple plantation may have some problems since the growing season of pineapple is eighteen months. In contrast, conventional organic matter would decompose at less than six months. In situ resistance organic matter is one of the alternatives and at the same time, supports the zero-waste program of the industry. A set of field research has been done on the pineapple plantation site of PT Great Giant Pineapple Plantation Lampung for one year based on randomized block design. Bromelain extraction waste product and chopped bamboo trees were used as the resistance organic matter resource. The resistant organic matters were applied at the rate of 0, 20, 40, 60, and 80 ton ha-1 to investigate its effect on soil infiltration rate, soil penetration resistance, and soil aggregate stability. The application of resistance organic matter has a positive impact on the parameters investigated. The infiltration rate was very high at the first month of application but tended to decrease at 5th month of application and then leveling off. However, the value is constantly and significantly higher than control. Soil penetration resistance was significantly lower than control either at a soil depth of 0 – 10 cm, 10 – 20 cm, or 20 – 30 cm. Soil aggregate stability is higher than control at 5th month of application, the values slightly decreased at 11th month of application.

Abstract
Marine macroalgae are the prospective and promising Indonesian natural resources containing bioactive compounds. This study aimed at evaluating various seaweed species with optimal biological activity to mitigate in vitro rumen methane emission and to confirm their antioxidant properties. In addition, relationships among several phenolic fractions and methane (CH4) production of seaweeds were elucidated by Pearson Correlation to screen seaweeds for their capacity to reduce CH4 formation. For in vitro batch cultures experiment, the diets were 500 mg of a substrate of seaweed. They were incubated with 50 ml of buffered rumen fluid (1:2 ratio of rumen fluid to buffer media) in a 100 ml serum vial at 39°C for 72 hours incubation time. A randomized block design was carried out with 14 dried seaweed treatments and 5 different cattle rumen fluid groups as a block. For total phenol, flavonoid, and antioxidant activity, a completely randomized design with 14 treatments and 3 replications was carried out. Data were analyzed by Analysis of Variance (ANOVA) and Duncan analysis. The results showed that the lowest methane production (ml/g DM incubated) significantly (P<0.05) was reduced by Halymenia sp. (0.24) and Caulerpa racemosa (0.41). Caulerpa racemosa showed high flavonoid content (1.5 mg Quercetin/g) and Ulva lactuca had the highest phenol content (0.55 mg Gallic Acid/g). Gracilaria coronopifolia had strong antioxidant activity DPPH radical scavenging activity (77.5% inhibition). It was concluded that Halymenia sp., Caulerpa racemosa and Gracilaria coronopifolia could be used as methane inhibitors and antioxidants for ruminants.
Effect of Coal Ash Enriched Compost on Soil Chemical Properties of Ultisols
Authors: Putri A , Iskandar I , Oktariani P , Limin A 
Published: December 2023

Abstract
Ultisols are soils that develop in humid tropical areas and are formed due to an intensive leaching process, resulting in the accumulation of clay in the subsoil. A decrease in the chemical-physical properties of Ultisols, such as a decrease in the levels of organic C, total N, cation exchange capacity (CEC), base saturation, and on the other hand, an increase in Al saturation and soil bulk density, can occur as a result of continuous monoculture cultivation. Improving the quality of degraded soil is usually carried out by amelioration using compost. Still, the addition of compost often only has a significant effect on improving the physical properties of the soil. Coal ash in the form of fly ash-bottom ash (FABA) is a waste product from burning coal in electric steam power plants. The amount of FABA is very abundant and its utilization is minimal. FABA has an alkaline pH and contains various nutrients in varying amounts. Therefore FABA has the potential to be used as an ameliorant to improve the chemical properties of acid soils such as Ultisols. Experiments with the spread technique of compost+FABA at a dose of 50 tons/ha and in rows technique at a dose of 25 tons/ha, 15 tons/ha, and 5 tons/ha were conducted to determine the effect of the treatment on soil chemical properties. Application of FABA-enriched compost in rows technique at a dose of 25 tons/ha had a significant effect and showed the best soil chemical properties, including increasing organic C, total N, total P, available P, exch-K, -Ca, -Mg, and -Na, CEC, base saturation, and decreased Al saturation. Utilization of FABA as a soil ameliorant combined with compost can improve soil quality more effectively.
