The effect of chemical fertilizer and bioorganic phosphate on the P-available, P-uptake, P-residue and the yield of soybean Lolita Endang Susilowati, Zaenal Arifin and Bambang Hari Kusumo University of Mataram Abstract The availability and residue of phosphate in soil are influenced by the addition of phosphorus (P) fertilizer and its uptake by plant. The addition of P fertilizer also commonly affects the plant yield. This research is aimed to assess the effect of chemical fertilizer and bioorganic phosphate on the P-available and P-residue in soil, P-uptake by plant, and the yield of soybean. Field experiments were carried out in a Vertisol of South Lombok, Indonesia, which consisted of four treatments arranged in a randomized complete block design and replicated five times. The four treatments were P0 = control, P1 = biorganic-phosphate + 125 kg PHONSKA ha-1, P2 = biorganic-phosphate + 187,5 kg PHONSKA ha-1, and P3 =250 kg PHONSKA ha-1. The P2 treatment resulted the highest P-available and P-residue in soil, the highest P-uptake by plant, and the highest yield of soybean. Meanwhile, the effect P1 and P3 on all parameters were not significantly different. There is a strong positive correlation (r = 0.97) between P-uptake by plant and the yield of soybean. As the P2 treatment produced the highest yield of soybean, this indicates that the application of bioorganic-phosphate can reduce the dosage of chemical fertilizer by up to 50%.

The ABC analysis used in this study is a method of making groups based on the ranking of values from highest to lowest cost. The ABC analysis is divided into three broad groups called groups A, B, and C. Group A is the most "important" material for the company (fast-moving) for stock material not to be empty, so it needs to be considered better. Group B is a slow-moving item, and Group C is a dead stock category of equipment whose inventory does not need to be too large. Grouping using this principle will help focus more on high-value items (group A) and provide sufficient control for low-value items (group C). Based on the method used for material classification, the results obtained for category A are 43%, category B is 16%, category C is 41%. Companies should pay more attention to category A to maintain material stability in the warehouse.

The Berth Allocation Problem (BAP): Study Case at PT Koja International Container Terminal Jakarta Indonesia Vivian Karim Ladesi (a*), Siti Sahara (b) a) Department of Transportation, Port Management Study, Universitas Negeri Jakarta, Jakarta 13220, Indonesia *vivian_ladesi[at]unj.ac.id b) Department of Transportation, Port Management Study, Universitas Negeri Jakarta, Jakarta 13220, Indonesia Abstract The berth allocation problem (BAP) is part of the key decision problems at port terminals. The BAP becomes important to the operational efficiency of a port for reducing the total cost because at the tactical level in order to achieve the optimal allocation which is used as a basis for making a deal between terminal operators and shipping lines which will determine the length of berth time vessels in port. Most of the tactical BAP models have used the assumption of deterministic situation where arrival time and number of containers are known in advance. Deterministic situations like that will be difficult to happen in real life. Therefore, this work tries to show the stochastic behavior of the BAP at PT Koja International Container Terminals, Jakarta as a case. The results provide the stochastic illustration as the difference between the estimated and the actual arrival or departure time of vessels as well as the variations and fluctuations in the amount of container loading and unloading at each different time Keywords: Port; berth allocation; scheduling; uncertainty Share Link | Plain Format | Corresponding Author (Vivian Karim Ladesi)

Rising prices, the difficulty of access and consumption of fuel that is done continuously is crucial. The impact is that there are still many coastal communities that suffer from lack of fuel for fishing and meeting their daily needs. This condition shows that there is a need for maritime technological innovation with renewable energy that is environmentally friendly and easy to operate and reach by coastal communities. Technological innovation with the use of three renewable energy sources is a renewable energy innovation that uses three energy sources as an energy source for electricity generation. The electricity generated from the accumulation of the three energy will be stored in a battery and then used to drive the fishing boat engine and generator as a power plant for the coastal community. The purpose of this paper is to find out the system design and usage concept of "Winner (Wind, Wave, and Solar Energy): Technological Innovation by Utilizing Three Renewable Energy Sources as a Solution of Fuel Scarcity for Coastal Communities in Realizing the Industrial Revolution 4.0". The writing method of this paper uses research and development with the ADDIE development model. Technological innovation using three renewable energy sources is an affordable, inexpensive and environmentally friendly technology and is a long-term investment. With the application of technological innovation by utilizing these three renewable energy sources, it is expected to meet the needs of coastal community energy sources and be a solution to the scarcity of world fuel oil.
