Indonesia is the largest archipelagic country in the world and has various marine resources. Fishery development is one of the priorities of East Java Province Government and the selection of the superior fishing commodities becomes important to fishery growth. The objective of this research is to select the superior fishing commodities in Southcoast of East Java Province, including eight Districts: Pacitan, Trenggalek, Tulungagung, Blitar, Malang, Lumajang, Jember, and Banyuwangi. Both Location Quotient models in quantity and value are developed and the fishing data during 2013-2017 are adopted in the study. As results, the superior fishing commodities by quantity, by value, and by both quantity and value are selected for the whole Southcoast of East Java Province and eight districts respectively. The result shows that the most fishing commodities quantities of production are Scads, Fringe scale sardinella, Short bodied mackerel, Indian oil sardinella, Skipjack tuna, Anchovies, Big eyes, Kawa kawa, Frigate tuna, and Hairtail. The biggest production is scad. The most valuable fishing commodity in Southcoast of East Java Province is hairtail with 154,324.8 million rupiah, while Tuna and Skipjack generate value amount 484,652.43 million Rupiah each year. Finally, policy implications and strategies are proposed for the superior fishing commodities in Southcoast of East Java Province.

In running farming system, farmers not only have a role important as owners who land they farm. But also they are as farm managers to make any decisions to face their farming problems under risk and uncertainty. These problems are categorized as internal and external factors related to price fluctuations of agricultural commodities. For that reason, farmers need to consider some strategies to overcome their farming problem for instance by choosing the best commodities that would give them an optimal profit. The maximax, maximin, savage, and laplace criterions were used to analyze decision making of horticulture farmer in determining which best horticultural commodities to plant according to their behaviour and attitude toward farming risk. Thus, horticulture farmer will be able to make a choice whether or not it is potato, cabbage, or, scallion that will be cultivated in the next planting period. Potato farmers are categorized as the optimistic farmer who loves farming risks and they are cautious. While scallion farmers are pessimistic farmers and they are risk averse. In addition, cabbage farmers are the ones who have the least regret.

Red chilli (Capsicum annumm L.) is a commodity with high price fluctuations. Market participants use red chilli price fluctuations to manipulate price information and cause information asymmetry. So that, the price information is not transmitted properly and indicates the market is not integrated. This study aims to describe price developments and analyze the integration of the red chilli market in Malang Regency, Malang City, and Surabaya City. The analytical method used is descriptive statistics, Johansen cointegration, and Vector Error Correction Model (VECM). The results showed that the price of red chilli fluctuated. Red chilli price fluctuations occur because production is seasonal, causing the distribution of chillies to be uneven every month. Therefore, efforts are needed to regulate cropping patterns so that the supply of chilli is always available. The results of market integration show that all variables are cointegrated in the long run and not integrated into the short run. This indicates that price information is transmitted imperfectly. Therefore, it is necessary to improve the information system so that all market participants can access market information.

Regional development is an important aspect in improving the regional economy, and its relationship with the national economy. East Java Province is one of the regions with the most potential agricultural sector and is the highest national granary area in Indonesia. Maximizing the potential of the resources owned by East Java will accelerate the development process and increase the regional and national economy. For the economic growth,this study aims to examine the crops performance to estimate the pattern of regional economic growth in East Java. The time series data of East Java Central Bureau of Statistics from2008 to 2017 are adopted. The location quotient analysis and shift-share analysis with three indicators, namely regional economic growth, proportional shift growth, and differential shift, are used.The results showed that crops such as corn, green beans, peanuts, soybeans, rice, sweet potatoes, and cassava in 29 districts and 9 cities of East Java have crucial performance and economic growth patterns. As the results, to consider and identify priority policy plans to accelerate regional economic development and growth are suggested.

The agricultural sector needs to make breakthroughs in the design of production systems to improve farmers' income and operation efficiency. One of the ways is to redesign rice production methods by applying a rice-fish farming system. Lamongan has a different system that combines rice cultivation with vannamei shrimp. Due to the limitation of farmers, the efficiency of the system has not yet reached the optimal level. This study describes the rice-fish farming system, identifies the SWOT and generated the grand strategy matrix, and analyzed the profit efficiency using Stochastic Frontier Analysis. The results showed that the strengths and opportunities are more influential, where the position was in the quadrant I; which means it is in a good strategic position. Meanwhile, the input factors which significantly influence profit where the cost of paddy seed, the cost of organic fertilizer, the cost of inorganic fertilizer, the cost of pesticide, and the cost of shrimp feed. The profit efficiency analysis shows that respondents engaged in this system did not efficiently allocate inputs and production cost factors appropriately. The average profit efficiency level was 78.05 percent; it means that there were still opportunities to increase profits from the system by 21.5 percent.
