Authors: Sari Komala 
Published: December 2019

Abstract
The rapid growth of population and development has changes in the land use. A lot of opened land or forest has changed into the settlement or industry. This change had made the power of absorption function becomes low instead the surface run off which results in shorter time water retention so that accumulation of collected rainwater exceeds the existing drainage capacity. The basic concepts of sustainable drainage development is increasing the use of water, minimizing losses, improving and conserving the environment. Drainage management model developed is using eco drain approach, which is an integrated and comprehensive approach and incorporates ecological or environmental factors in every drainage management effort. This research aims to (1) analyze the characteristic of physical area, environment condition, economy and social community in Pekanbaru City, (2) analyze other important factors affecting the drainage performance that impacted ecology aspect, economy and social community in Pekanbaru City, (3) design the management strategy of sustainable drainage in Pekanbaru City. This research was carried out in Pekanbaru City. This research was a mixture of quantitative and qualitative research. The research methods used were survey and experiment methods. The method of data collection was done through field surveys, documentation, and questionnaire distribution. In quantitative research the data obtained based on questionnaires that were analyzed statistically. Based on data analysis and evaluation, needed strategies for sustainable drainage management in Pekanbaru City. The results showed that the existing drainage channel was unable to accommodate rainwater runoff discharge where (Qp) is greater than Q-exist. Based on the analysis that has been carried out, the sustainable drainage management strategy in the city of Pekanbaru includes 3 (three) aspects, (1) ecology, (2) social, (3) economy. Ecological aspects include drainage management strategies such as normalization of drainage channels and eco drain. Social aspects include participation and community empowerment that actively supports drainage management. Economic aspects include the participation of stakeholders such as the government and the private sector as well as the community in making efforts to manage and maintain drainage facilities and infrastructure.

Abstract
To understand the effects of various dietary sources on the biological changes of a subterranean termite, Coptotermes formosanus Shiraki, the three lignocelluloses, i.e: softwood, hardwood, and grass with the different of samples shape/size (intact and powdered) were subjected to C. formosanus, and we analysed the biological changes of C. formosanus workers (survival, body mass and the presence of protists). The results showed that at the end of observation, the survival, body mass and presence of Pseudotrichonympha grassii and Holomastigotoides hartmanni in the guts when consumed wood diets were much higher than those of the termite workers when consumed rice culm straw diet, whereas the presence of Spirotrichonympha leidyi in the guts were similar for all the samples. We failed to detect significant difference between intact and powdered diets from each lignocellulose, suggesting that the difference of lignocellulose shape/size (intact and powdered) had no effect on the biological changes of a subterranean termite, C. formosanus.

Published: December 2019

Abstract
It is necessary to estimate the total carbon of forest or agroforest biomass using satellite remote sensing technology since the areas of Indonesian forests and agroforest are very large. However, ground truthing a large area would be time consuming and expensive; and the results might be affected by changes in the vegetation structure over the duration of the survey. Moreover, this method was also effective in monitoring changes in biomass and carbon by year. This study was therefore critical due to the lack of similar studies in Indonesia, especially on Sumatera Island. This study has the puspose to estimate the total biomass and biodiversity value in Damar agroforest; and investigate the relationship between the carbon stock in agroforest biomass and the pixel value, and continued mapping the carbon. In addition, simple linear regression and multiple linear regression were applied to analyse the single spectral band ratios of 1 to 5 and 7; and it also applied the 10 vegetation indices such as Simple Ratio 4/3, NDVI, SAVI, Brightness, Greenness, Wetness, TNDVI, ND 73, Simple Ratio 7/3, and Ratio 327 as a biomass predictor. The results have found that the dominating species (51 %) was Shorea javanica belonging to the family of Dipterocarpaceae. In addition, 73 species belonging to 35 families were identified. Biodiversity was identified to be moderately stable and the distribution of species abundance falls in the moderate category. Thus 70 % of Damar agroforest areas might be dominated by one or more species. The significant model was successful in finding in spectral reflectance at band 7. In addition, the model based on simple linear regression produced of R2 = 0.44; F-stat. = 14.88 > F crit. = 4.38, p-value = 0.001, df = 1, 19; and the model has the lowest value of RMSE = 52.84. This model was chosen as the ideal model to predict a carbon content in Damar agroforest with equation Y = 267.83 – 1625.5 band 7. The average carbon content was estimated to be 130.19 Mg C/ha, such carbon content was nearly equal to that of Dipterocarp forest. It is therefore important to maintain the Damar agroforest ecosystem services with high biodiversity as well as natural forest; furthermore, it is also a preferable site for carbon trading.

Authors: Widiastomo Triyoga 
Published: December 2019

Abstract
Decentralised government aimed to enhance local participation in regional development. The regional governments have been mandated by the central government to implement carrying capacity assessment to ensure that the ecosystem services would be maintained and adequate to meet the demands. Based on the carrying capacity assessment in Seruyan of Central Kalimantan, the recommendations related to emissions from deforestation and forest degradation are: 1) to protect all existing forest covers in the north; 2) to restore areas within the forest and national parks; and 3) to restore riparian areas and areas with slope > 45%. By implementing all these recommendations, the district would be able to reduce an annual emissions of 3.7 MtCO2e and 1.3 MtCO2e compared to the district baseline and BAU scenario, respectively, until 2030.

Abstract
The relative impacts of the El Niño-Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) events of Rice Cropping Calendar on Equatorial and Monsoon Region of Indonesia were studied. The spatial distribution of partial correlations between rainfalls with the ENSO and IOD over West Sumatera and West Java indicated a significant impact on rainfall anomalies normally along the period of September – November. The ENSO and IOD events, which is known as a monsoon type, had a wider impact in West Java, especially over northern of West Java. On the other hand, there was only a little impact of the ENSO and IOD on rainfall anomalies in the southern-west of West Sumatera. This strength was shown to be associated with the evolution of distinct weather types revealed by Pearson analysis. In these regions, the same impact of the ENSO and IOD on the width of planting area was very weak in the period of December-March whereas that in the period of June-November the impact on West Sumatera reached only 10% moreover, the impact in West Java could reach up to 80%. On the period scales, the ENSO and IOD events had significant impacts to delayed onsets of rice cropping calendar in which they were more intense than previous ones. In general, the magnitude of ENSO-delayed onsets was greater than delays to the IOD. The period-stratified ENSO variability during each of the months from September to November had a significant impact of delayed planting 2 to 4 dekads in West Sumatera and 4 to 6 dekads on West Java. This confirmed that strong ENSO events indeed affected the southern of West Sumatera and northern of West Java. Meanwhile, the period-stratified IOD variability on West Sumatera and West Java had a significant impact of delayed planting 2 to 4 dekads.
Potential of Land-Based GHG Mitigation Policy to the Indonesian Economy

Published: December 2019

Abstract
Indonesia GHG emission mostly originated from the Land-Use Change and Forestry (LUCF) sectors. The complexity of land conversion pattern and different carbon stocks for each land type makes have made the mitigation and emission calculations for the LUCF more challenging. However, the Indonesian government has already introduced some policy package to reduce the deforestation and increase the reforestation. Here we, simulate the policy to reduce deforestation by increasing the yield of the crops, and increase reforestation. The simulation was done by using the Computer General Equilibrium (CGE) combined with Land Conversion Matrix. The focus of this study was to observe how mitigation, especially from the land-use sector, would affect the economy under the low and high economic growths. The results indicated that the mitigation policy would hit the Indonesian economy harder under the low economic growth, since under the low growth, Indonesia might experienced around 2.7% of GDP loss in 2030 compared to the BAU level. However, if Indonesia is able to achieve high economic growth, the introduction of mitigation, especially through the improvement of crop productivity, might produce better implications to the economy. However, this result also might be overestimated, especially for the GDP due to the consideration of high economic growth and several study limitations in this paper.

Abstract
Around 10% of the population in Tasikmalaya and 8% in Sukabumi Districts are below the poverty line, of whom some lived in upland areas. This paper analysed the local farmers’ strategies in mitigating drought. The planting pattern in both districts varied, rice-rice-CGRT crops, rice- CGRT crops -rice, rice- CGRT crops -not planted and rice- not planted -not planted. This diverse planting pattern occurred because farmers are dependent on the rainy season. This paper described alternative food crops selection strategies for the farmers to mitigate drought.

Abstract
Modelling is used to provide an outlook and evaluate scenarios related to energy efficiency potentials from end-user in various sectors including industrial sectors. The modelling tools used ExSS (Extended Snap Shot) and GAMS (General Algebraic Modelling System) as solver. Three scenarios were developed to envision Indonesia paths in energy savings potentials, namely business as usual (BaU or baseline) and two counter measure scenarios (CM 1 and CM2). Base year was set to year 2010, in line with NDC scenarios and projection. In the baseline scenario, it is assumed that in the future years (after 2010) there were no increase in renewable energy utilisation and rise in electricity demands would be provided by coal and natural gas fired power plants. The economic structures that were incorporated in the model for the target year 2030, was assumed to be have the same value as that of 2010’s. Accordingly, structures of energy demand in end-user sectors would not change from 2010. There would be no changes in share of transportation modes. Similarly of efficiency of equipment in household, commercial and industrial sector were also indifferent to that of the 2010 values. CM1 was developed to envision the development path to achieve energy savings through the implementation of more efficient energy technology in end-user. More efficient equipment or best available technology (BAT) were expected to be implemented in various sectors, however the penetration in industry was still 5% less than other sectors (household, commercial and transportation). At this rate, BAT penetration for household, commercial and transportation sectors could reach as high as 20%. CM2 was set to be more advanced in implementing the BAT. As much as 10% increased in BAT penetration was projected to be realised in each of end use sector, i.e., household, commercial and transportation. Although, the BAT penetration in industry sector was still 5% less than others, the BAT could rise up to 25% for industry and 30% for non-industrial sectors. Parallel with this measure, biofuel demands would also increase to 10% by force of strictly implementing regulation. Baseline scenario estimates of the total final energy demand has increased by 2.5 times, from 143,747 ktoe in 2010 to 364,627 ktoe in 2030. The associated GHG emission from the related energy consumption in 2030 was estimated to be around 1,642,009 Gg CO2e, which was higher by almost 4 times the GHG emission level in 2010 (416,530 Gg CO2e).
Comparative Study of Methods to Estimate Historical Peat Burnt Area in Gaung – Batang Tuaka River of Peat Hydrological Unit (KHG)

Published: December 2019

Abstract
As a country with 14.9 ha of peatland, Indonesia is a major contributor of GHG emissions, especially from peat ecosystems. These emissions were caused by peat decomposition and peat fires. However, accurate estimation of peat burnt area was still a barrier that prevented the inclusion of peat fire emission in the document of Forest Reference Emission Level (FREL) as a followup document to REDD+ activities. This research has the objective to analyse two different approaches to estimate peat burnt area used in the FREL document and the most recent semi-automatic approach suggested by the Ministry of Environment and Forestry (MoEF). The study focused on the Gaung – Batang Tuaka River Peat Hydrological Unit (KHG), as one of the KHG priorities in Indonesia. The results showed that the average total annual burnt area from the FREL approach was 58% higher than that of the semi-automatic approach, which could lead to an overestimate of peat fire emissions from this approach. The burnt area identified in this study was found to occur within the production forest area. As stepwise approach is allowed for FREL submission, improvements to a higher precision method are necessary to increase the accuracy of burnt area estimation.

Abstract
Development of timber industry and demand for wood in Indonesia must be balanced with an enhancement of timber production. Utilization of fast growing species such as sengon (Falcataria moluccana) may be done to increase the timber production. The optimal use of the land will be achieved by applying agroforestry system. This research aims to compare the growth between local sengon and solomon sengon in agroforestry system. The research showed that provenance is significantly influence the diameter. The interaction between provenance and planting technique do not affect the height, diameter, canopy area, depth of rooting system, root lenght, and root diameter horizontally. Solomon sengon F1 with opened polybag treatment revealed the highest average in diameter. The best average of depth and root diameter was found in closed polybag treatment, whereas the best average of root lenght was found in opened polybag treatment.
