Abstract

An evaluation of the condition and performance of the BBT Port needs to be carried out because of the significant increase in the number of tourist visits to the Bintan Beach International Resort area. Still, since its inauguration in 1994, the port has not changed much. Passenger terminal needs are commonly defined through projections using the exponential trend method based on ship and visitor flows in the last five years. A port performance is based on BOR (Berth Occupancy Ratio) calculation. In contrast, for the performance evaluation of passenger terminal services is based on the perception of tourists as passenger terminal users obtained from the questionnaire results with a Likert scale and the Importance Performance Analysis (IPA) method from the IPA, interviews with the BBT port manager, are conducted by using the Strength Weakness Opportunities Threats (SWOT) method to formulate the development strategy. The analysis result shows that it needs to increase the waiting area up to 613 m² in 2033, and the parking area of 17,173 m², while the BOR at the BBT port is still in a proper category, by  24.11% of the UNCTAD 50% requirement. In evaluating the passenger satisfaction to the port services, the improvement focuses on the priority quadrant, namely the physical condition of the BBT port facilities. Next, formulating a development strategy in terms of physical aspects and management to adjust the passenger needs, and the BBT port is ready to face business competition in the future.

Abstract

Branta Port, located in Pamekasan Madura, is a connecting port area around Java Island and Madura Island. The port has an important role in logistics and supply chain activities as well as economic development in Indonesia, especially in Java and Madura. But the reality is Branta Port has some shortcomings in the port facilities to security sector. It based on the lack of regulation enforcement of the port management itself. The lack of renewal of the port master plan is also one of the obstacles to the port's poor performance. Therefore, with this research, it is expected to obtain a broad picture of the development strategy at the Branta Port. The methods are Location Quotient (LQ) & ships loading and discharge at port forecast using several forecasting analysis. The results show the ships call, loading and discharge flow at Branta Port have a fluctuating pattern follow the seasonal trends in salt production activities in Madura region. Where in 2039 (long-term) the loading and discharge flow at Branta Port is predicted to reach 380,927 tons which in 2018 amounted to 139,855 tons. The results of the port performance calculation are performed using port performance indicators called Berth Occupancy Ratio (BOR), where the BOR value from year to year to the long-term forecasting year (2039) is 22.08%, which is still below 40% for an additional indicates that the jetty is not busy according to UNCTAD criteria. Whereas the need for port facilities such as warehouses and stacking fields has increased. The development strategy focused on port facilities such as the berth length expansion from 100m to 186m, construction of port warehouses of 183m2, improvement of several port facilities such as navigation facilities and causeways, also the addition of port waste treatment facilities.Keywords: Location Quotient, forecasting, econometric method, Berth Occupancy Ratio

Abstract

The construction of the Meninting Reservoir was planned with the objective of meeting the irrigation and domestic water demands on Lombok Island. It served as a multipurpose reservoir, with a maximum storage volume of 12.18 million m³, mainly for supplying irrigation and domestic water. The reservoir had considerable potential for water availability, which could be used to supply water to the South Lombok region with limited water availability but had agricultural land potential. Therefore, this study aimed to evaluate the potential of Meninting Reservoir water availability and its optimum utilization for irrigation and domestic purposes. The irrigation water demand for 1,559.29 ha and domestic water demand of 150 ls-1 was fulfilled by Meninting Reservoir. Water availability in this Reservoir was estimated with the F.J. Mock method of rainfall-runoff model using 25 years of daily rainfall data from Gunung Sari and Sesaot rain gauge stations. The calibration process of the rainfall-runoff parameters models employed observed discharge data from the Aiknyet water level gauge station. The formula for optimizing reservoir water release was prepared using the linear programming method based on operational water level limits, inflow discharge, irrigation, and non-irrigation water requirements, including domestic water. The optimal average annual cropping intensity was 203.96%, 215.87%, and 241.41% for dry, normal, and wet years, respectively. The service reliability of irrigation and domestic water demands reached 100% for all inflow discharge conditions. The k-factor value met the minimum limit of 0.70 and 0.85 for irrigation and domestic water demands, respectively.
