"ABSTRAKIndonesia in general is an archipelagic country, but only eight provinces specifically have island characteristics, this is indicated by the comparison of land and sea area and the presence of islands. The big difference in the characteristics between the island province with the provincial non archipelago cause differences in the solution to any problems encountered. One of the problems faced by island provinces is the slow distribution of goods which results in the difficulty of production competitiveness, the decline in the quality of goods consumed by the people and the price disparity felt by the people in the islands. The existence of sea tolls has not been utilized optimally especially by island provinces in the eastern region of Indonesia. This study aims to outline solutions to overcome problems related to goods distribution and accelerate economic equality in island provinces, especially those located in eastern Indonesia. The method used in this study is a description and analysis of exploration. Some of the solutions outlined are the utilization of the sea tolls and cooperation with pioneering shipping to build special supply chains, map the potential of the region, and develop potential centers. In addition to the sea toll, Bulog's role as an institution that can support distribution and warehousing is also sharpened. As a supporter of transactions and distribution, the role of PT Pos Indonesia and cooperatives was also considered. Both institutions can act as financial intermediary services related to joint accounts, savings and loans, and guaranteed transactions. this is done so that the potential of all levels of society can be maximized. furthermore, the role of the regional government as a policy regulator also has a role in the use of infrastructure sharing."

"The research aims to scale up a small-scale stirred batch reactor to a large-scale stirred batch reactor in order to degum crude palm oil for use as a raw material in biodiesel production. The scale-up is based on the similarity of fluid Reynolds numbers in the two differently sized reactors. To achieve this aim, computational fluid dynamic modeling and simulations of the two reactors were performed. A small-scale palm oil degumming process was carried out in a 250 cc autoclave reactor using a magnetic stirrer at 500 rpm. The simulation results of this small reactor yielded a fluid Reynolds number in the range of 5 to 3,482. The large-scale reactor proposed in this research is 1.25 m3 in volume and is equipped with two impellers: a pitched blade impeller and a Rushton turbine impeller. The pitched blade impeller is placed over the Rushton turbine impeller. They are rotated at 100 rpm. Under this setting and operation, the resulting fluid Reynolds number was in the range of 486 to 202,000. This result indicates that the large-scale reactor was able to reproduce the reaction performance obtained in the small-scale reactor."
