The objective of this study is to analyze sustainability achievement level of palm oil plantation management based on integration principle and criteria of ISPO and RSPO. The sustainable development on palm oil are presented through 5-dimensional these are legality of plantation business, management of plantation, management and monitoring of environment, responsibility towards workers and social responsibility and community empowerment. This study was conducted in 5 estates and 3 palm oil mill of state own company in Riau Province. The study was conducted through audit method using checklist of plantation management on sustainable development standard. Results of descriptive analysis showed that the implementation standards based on sustainable development dimensions of palm oil showed achievement level of 82.43%. This achievement became a baseline for management to improve their performance which was focused on the attributes in each dimension. This study is relevant to be implemented on similar industries, due to the checklist instrument is easily adopted for assessing the plantation management achievements based on sustainable development standard.

:Coastal area activity on human exploitation greatly affected aquatic ecosystems. Land changes disturbed the level of soil stability, soil will be easily eroded by the flow of water, the surface tide ran off to the sea. North waters of the island of Bengkalis is a place boiling down to several rivers, including the river Jangkang and river Liung. The rivers have affected the concentration of total suspended solid (TSS) in the strait waters of North Bengkalis Island. This research demonstrated water sampling by using sampling point determined by purposive sampling method mixing the layer of water depth ratio. The results based on satellite imagery data showed that TSS was quite high in the West season period until the transition period I (West to East) with a large concentration value of 200 mg / L. For the lowest TSS concentration occurred in the East season i.e., between 0 -200 mg/L. TSS concentrations that dominated in the East season ranged from 51 to 75 mg/L This value was higher than the TSS concentration of field data analysis, i.e., between 23 -39 mg/L. Changes of coastal coastline of North Bengkalis during the last 20 years continue to change the size of the land area, with a land area of 131 ha lost.

In the last few years, interest in improving the teaching of translation increased immensely. Proposals of introducing many methods to raise students' involvement and centeredness in the process evolved and many concepts from other disciplines were implemented. One of these evolving concepts was Project Based Learning (PBL) which was popular across many education fields: the main essence of it is involving the students in an authentic and practical translation project. This article investigates the experiences of Saudi under-preparation-translators in a Computer Aided Translation (CAT) course that was introduced using the PBL method. Using qualitative methods (mainly interviews and observations), students' receptions were collected and analyzed and themes were elicited to report the students' attitude to PBL method. Although many positive experiences such as autonomy and team work skills were reported, some indicated the concerns of the practicality of the procedure as well as time issues.

This paper presents the application of detached breakwater to reduce wave energy for protecting mangrove planting site. Initial planting of mangroves still needs seawater for their growth, but they will be distracted by the big wave. How is the detached breakwater should be designed for this purpose is the objective of this research. This research simulated the wave propagation at the existing condition and under some alternative designs of detached breakwater to find out the optimum design of detached breakwater for mangrove planting site. The CADMAS-SURF is a numerical model that was used for the simulation. Bengkalis coast in Indonesia was picked up as study area of this research. The mangrove degradation and the severe coastal abrasion have occurred in this area for long period. The simulation result shows that in the high tide condition, the wave height and wave velocity at the mangrove plantation area are about 1.12 m and 3.86 m/s respectively in the case of the existing condition. In this case, the initial mangrove plantation cannot be applied because it will be destroyed by the wave. By applying breakwater both for rubble mound type and vertical wall type, the wave height and the wave velocity were reduced to 0.69 m, 2.39 m/s and 0.72 m, 2.31 m/s respectively. In this case, the initial mangrove plantation can be applied because it will not be destroyed by the wave.

Rangsang Island is home to more than 48,000 residents. Climate change has been a critical issue to the Island and threatened the existence of the inhabitants. This study is proposed to identify the zone of the coastal area of Rangsang Island which is vulnerable to climate change. By mapping coastal vulnerability index (CVI) of the island, it is expected to be a reference of local government in planning their spatial management. The method of this study was by a direct survey for collecting data of geomorphology, beach elevation, sea level rise, tidal fluctuation, significant wave height, and changes in the coastline. To determine CVI, each parameter is divided into 5 categories and given a value level: 1 for very not vulnerable, 2 for not vulnerable, 3 for moderate, 4 for vulnerable, and 5 for very vulnerable. The results show that most villages on the island are classified as highly vulnerable to climate change, namely 9 villages. Even 2 villages are threatened very high risk because the village has CVI more than 12.5. Only 6 villages whose territory has moderate vulnerability index. Vulnerability level of coastal Rangsang Island is strongly influenced by geomorphological variable and coastal elevation. In addition, the variable coastline changes and sea level rise also contributed to the vulnerability index of the Island.
