Indonesia, as the world’s largest archipelagic country, should take into account the critical role of maritime transportation as a basic infrastructure for connecting inter-island economic activities. According to the National Logistics System, Indonesia should have its own international hub port in the future, thus this study is required to analyse the connectivity between main domestic ports and international hub ports in Indonesia. A heuristics approach is applied by combining the Feeder Network Design Problem and Multiple Commodity Network Flow Problem to create the optimum routes as well as to allocate the cargo by minimizing the total transportation costs. Two scenarios are conducted in the calculation, in the first scenario, we analyze all international containers of six main domestic ports (with Belawan), while the second scenario does not consider on the international containers in Belawan (without Belawan). The second case corresponds to directly delivering all international containers to Belawan, without considering these for the connectivity network. In conclusion, each route will have the fewer legs and shorter distances if the larger ship capacity used, consequently, the lower total shipping costs will be gained on these routes.
The purpose of this paper is to review and evaluaute the clinical dataon incidence, sex, body-weight, morbidity and mortality and the possible etiology of convulsions occurring in the neonatal period (i.e. the first 30 days of life) and to study the outcome in follow up examination at the age of more than 6 months. The age of 6 months is taken as a limit because previous experiences and those of other authors (Billing, 1964) have shown that only after the age of 6 months neurological and mental disorders remain evident and permanent.
Indonesia is a primary world cinnamon exporter, half of the world’s consumption is supplied by Indonesia. From every retail transaction, some 25% goes to the farmers. Farmers do not have so much benefit from the increasing export price. The rise of e-commerce seems to be a promising instrument. This e-commerce grows rapidly particularly in Indonesia. The improving internet connection speed and bandwidth results in a growth of internet users. The aim of the study is to investigate the viability of improving logistic system by using e-commerce for export. The case study is the cinnamon export from Padang to Baltimore, with annual demand of 21 ton. At present, the delivery of cinnamon from the farmer to end user takes in average 59 days with a shipment cost of IDR 113,000/kg (USD 7.94/kg). By using e-commerce, a small size delivery could be shorter, namely only nine days, with a shipment cost of IDR 299,300/kg (USD 21.04/kg). Considering the frequency of shipments, cash flow, and deteriorating quality and price for a long shipment, it is found out that e-commerce is very promising alternative for cinnamon export, where the total point-to-point shipment would cut by half. For large shipments by exporters, a substantial benefit is obtained from a shorter delivery time of 29 days, with the same unit shipment cost. It is obtained that marketplace scenario is the most optimum with total logistics cost and time for about IDR 113,000/kg (USD 7.94/kg) and 9 days respectively.
