Abstract

Penelitian ini bertujuan untuk menganalisis efisiensi teknis diantara petambak udang dengan menggunakan pendekatan stochastic frontier yang digabungkan dengan model efek inefisiensi. Data dikumpulkan dari 245 sampel petambak udang di Kabupaten Lamongan, Banyuwangi, dan Pacitan menggunakan kuesioner terstruktur. Hasil empiris menunjukkan bahwa tenaga kerja, pupuk, pakan buatan dan padat penebaran adalah faktor-faktor yang mempengaruhi variasi dalam output. Hasil analisis menunjukkan bahwa 68% () kesalahan acak yang dihasilkan oleh model disebabkan oleh inefisiensi yang terjadi dalam proses produksi udang vaname. Skor efisiensi teknis petambak udang bervariasi, berkisar antara 0,77 - 0,97 dengan rata-rata 0,92. Faktor-faktor yang mempengaruhi inefisiensi teknis dalam budidaya udang vaname di daerah penelitian diduga berasal dari atribut yang melekat pada petambak udang seperti umur, tingkat pendidikan, dan pengalaman dalam budidaya vaname

Abstract

This article is related to the IbM program entitled Community Feed of Mina Mahardika Catfish Aquaculture Group in Seduri village, Mojosari district, Mojokerto Regency. Based on the identification of partner problems, the main problem facing by Mina Mahardika Group was the characteristics of fish feed produced by the group. The fish feed was very easy to be broken, suspended in the water and does not have enough buoyancy. The problems mainly because the production of the fish feed was still used a conventional technique. The IbM program reported in this article was intended to solve the problems by inducing the pellet making machine that can produce the fish feed having good texture and enough buoyancy for catfish aquaculture activity. The result of the IbM program indicated that the program can help the Mina Mahardika Group to solve their main problems and improve the aquaculture activity through community feed program.

Abstract

Fisherman Insurance Premium Assistance is applied to all coastal areas in Indonesia. In Malang Regency, it just started in 2016 through JASINDO, so many fishermen still do not fully understand the benefits against possible risks. Therefore, it is necessary to study the dynamics of the fisherman insurance system focusing on producing a model of insurance demand and the projection of the demand and growth of fisherman insurance in the future. The method used in this research was a series of system dynamics modeling. The results of the validity test in this study indicate the mean comparison and error variance is the following: fisherman insurance program = 4.8% and 6.01%; fishermen’s value = 4.0% and 21.55%  and premium assistance = 3.9% and 12.17%. Moreover, the structural and parametric scenario analysis results show the average value of the increase in tourists: Scenario 1 - Structural: Premium assistance = 602 fishermen, Scenario 2 - Structural: 394 fishermen, Parametric Scenario 1 - Optimistic = 578 fishermen, Parametric Scenario 2 - Most Likely = 289 fishermen, and Parametric Scenario 3 - Pessimistic = 201 fishermen. However, the projection of the demand for fisherman insurance in 2021-2029 has not shown the expected results. The largest number of demands is 421 and the smallest is 321 in 2026. Moreover, after several simulations, the study found the most possible simulation to be carried out and to have a significant, stable effect on the results desired by the government, which is through premium assistance. If at least insurance premium assistance of Rp. 118,000x109 can be given annually, it will be able to generate a fisherman insurance demand at a minimum of 500.

Abstract

Salt is one of the marine mineral products that has great potential in Indonesia. Salt production in Indonesia is mostly located on the island of Madura and the north coast of Java. Indonesia still imports salt to meet salt needs, especially for industrial salt needs. In increasing national salt production, one of the strategic steps that need to be taken is to increase the area of ??salt ponds in Indonesia. To increase the area of ??salt land, one important strategy is to open salt ponds outside the North Coast of Java and Madura Island. One alternative location is the beaches in the southern region of Java Island. Salt production on the South Coast of Java has not been done much. On the South Coast of Malang Regency, there is no salt production business. The creation of salt production in the South Coast of Malang Regency needs to be based on an analysis of market potential. This study aims to analyze the market potential of salt commodities in the South Coast of Malang Regency. This study is the first study to analyze the market potential for the development of salt production in the South Coast of Malang. The results of this study indicate that the main market potential for salt production in the South Coast of Malang is salt for fishery activities and salt for livestock. In addition, there is a potential market for salt education activities and consumption salt. Based on the results of this study, the development of the salt commodity market in the South Coast of Malang can be developed with a Niche Marketing approach.

Abstract

Salt is an essential commodity that is widely used for consumption and industrial purposes. One of the main factors determining the success of this salt production is the suitability of the salt production location. However, there has been no analysis of the suitability of salt production locations in salt production centers in East Java. This study aims to analyze the suitability level of the location of salt production centers for the salt production process using the Salt Location Suitability Index (IKG). The areas analyzed in this study are salt production centers in Sampang Regency, Probolinggo Regency, Gresik Regency, and Tuban Regency. The IKG analysis is prepared based on nine suitability parameters: rainfall, soil permeability, soil type, duration of exposure, humidity, wind speed, air temperature, evaporation rate and saturation level of raw material water. The IKG analysis results can also be used as a basis for recommending alternative technologies that need to be applied to increase salt production. The results of this study indicate that the locations of salt production in Sampang District, Probolinggo Regency and Tuban Regency, which are the focus of this study, are in the Very Appropriate category (more than 85%), while the locations in Gresik Regency are in the Sufficiently Suitable category (80-84 %). Based on the results of this study, all the locations that are the focus of this study are suitable for further development of salt production.
