As one of the world’s largest CPO producer, Indonesia uses CPO to produce biodiesel. European countries claim that production of biodiesel from palm oil contributes carbon emission to atmosphere along its production path. Furthermore, US EPA- NODA states that palm oil based biodiesel can only reduce GWP emission by 17% compared to fossil-fuel based. The minimum requirement to enter global market is 20% for US and 35% for EU. This condition could make barrier to Indonesia. Scientific approach through Life Cycle Assessment (LCA) can be used as a tool to assess this issue. Introduction The most reliable alternative for substitution of the fossil fuel is biodiesel.

Objective The objective of the research is to analyze and compare Life Cycle Assessment (LCA) of oil palm and Jathropa curcas as feedstock for biodiesel in Indonesia from cradle to gate using data based found in Indonesia Objective The objective of the research is to analyze and compare Life Cycle Assessment (LCA) of oil palm and Jathropa curcas as feedstock for biodiesel in Indonesia from cradle to gate using data based found in Indonesia Acknowledgement This research was supported by Directorate General of Higher Education, Ministry of Education and Culture of Indonesia under competitive grant and JSPS-DGHE Bilateral Join Research Project. Acknowledgement This research was supported by Directorate General of Higher Education, Ministry of Education and Culture of Indonesia under competitive grant and JSPS-DGHE Bilateral Join Research Project. Methods The system boundary for LCA study is shown in Fig.1., which is a cradle to gate assessment. The production cycle to be assessed consists of eight sub-processes. The functional unit (FU) of this study is 1 ton of biodiesel fuel (BDF) production from jatropha and oil palm. Data to be used in this study was from oil palm plantation in PTPN VIII Unit Kebun Kertajaya Banten and from Jatropha curcas centre Pakuwon Sukabumi West Java, and secondary data. Catalytic transesterification experiment was conducted in a facility owned by Agency for Technology Assessment and Application of Indonesia (Capacity = 1 ton BDF/day). Each stage of analysis and calculations was carried out before and after the plants yield the usable fruits. Based on the field survey, oil palm and jatropha will have stable productivity after 5 th years from seed plantation. Transportation from seedling to plantation area and from plantation to palm oil mills and from palm oil mills to biodiesel plant were also considered, palm oil mills assumed have implemanted methane capture, and excluding land use change.

Fig.1. The system boundary of this study Results From Fig.2 and Fig.3, it can be seen that the GHG value for oil palm is higher than Jatropha curcas in every stages except for planting and biodiesel production stages. The most significant environmental impact based on GHG value is caused by fertilizing and biodiesel production stages both at oil palm and Jatropha curcas Results From Fig.2 and Fig.3, it can be seen that the GHG value for oil palm is higher than Jatropha curcas in every stages except for planting and biodiesel production stages. The most significant environmental impact based on GHG value is caused by fertilizing and biodiesel production stages both at oil palm and Jatropha curcas Conclusions Utilization of agrochemical in form of fertilizer and plant protection generate significant contribution to environmental impact of biodiesel production i.e. 68.14% and 37.56% for oil palm and Jatropha curcas oil, respectively. The GHG emission value before stable productivity is 2575.47 kg-CO 2 eq./ton-BDF for palm oil and 3057.74 kg-CO 2 eq./ton-BDF for Jatropha curcas. When the productivity has reached stability, the GHG emission value is 1511.96 kg-CO 2 eq./ton-BDF for palm oil and 380.52 kg-CO 2 eq./ton-BDF for Jatropha curcas. The energy input in palm oil is higher than Jathropa curcas as show by higher the NEB which is 146948.08 and 39334.79 for oil palm and jatropha curcas, respectively and by lower the RI value which is 0.162 and 0.270 for oil palm and jatropha curcas, respectively. Compared to diesel fuel, CO 2 eq. emission is reduced up to 49.27% and 73.06% for BDF-CPO and BDF-CJCO, respectively Conclusions Utilization of agrochemical in form of fertilizer and plant protection generate significant contribution to environmental impact of biodiesel production i.e. 68.14% and 37.56% for oil palm and Jatropha curcas oil, respectively.

The GHG emission on BDF-CJCO Fig. 2 shows that oil palm’s GHG value of eight sub-processes which consist of land preparation, seedling, planting, fertilizing, protection, harvesting, palm oil mills, and biodiesel production is 0.44 %, 0.61 %, 0.91 %, 35.15 %, 15.31 %, 1.23 %, 22.90 %, and 23.44 %, respectively. While for Jatropha curcas as shown in Fig. 3 is 0.63 %, 0.74 %, 11.79 %, 29.49 %, 4.02 %, 0.48 %, 1.08 %, and 51.78 %, respectively Fig.4 and Fig.5, show that energy consumption for oil palm is higher than Jatropha curcas in every stages except for planting and biodiesel production. The largest energy consumption for Jathropa curcas occurs in biodiesel production sub-process i.e. 25623.45 MJ/ton-BDF.
