Abstract

The shrimp farming industry is a major pillar in the global fisheries economy, its high demand in the international market is a potential for gaining quick profits. However, the use of intensive cultivation technology by large farmers has been suspected in contributing to environmental damage. In light of this, the Ministry of Marine Affairs and Fisheries has implemented a sustainable fisheries development program with the goal of overcoming this negative impact, this includes the implementation of Good Aquaculture Practices (GAP) in accordance with Ministerial Regulation Number: PER.19/MEN/2010 concerning quality control and safety of fishery products. The purpose of this study was to analyze key factors in the application of Good Aquaculture Practices to shrimp farming. This study used a mixed method approach. Data were obtained from shrimp pond experts who joined the East Java shrimp entrepreneur community. The data analysis method used was the Matrix of Cross Impact Multiplication Applied to a Classification (MICMAC) structural analysis. The results showed that 2 variables had been shown to be the most influential and became the main drivers in the application of Good Fish Farming Practices management in shrimp farming, these variables are the "Use of Chemicals, Biological Materials, and Fish Medicines (UCBF)" and "Harvest" (HV).

Abstract

Today, the goal of sustainable development is a global problem all countries face.  Economic development does not pay attention to the environmental impacts, causing problems that occur today and risk future generations' survival.  Governments in each country are expected to participate actively in achieving sustainable development goals. On the other hand, governments also face problems of poor performance, corruption, collusion, nepotism, and slow public services.  Introducing a merit system is expected to improve the existing system of government. This article discusses the effect of implementing a merit system in realizing sustainable development. This research is located in the city of Malang. The sample comes from the State Civil Apparatus of Malang City Government consisting of structural officials, functional officials, and executive officials, with the Structural Equation Modeling Partial Least Square (SEM PLS) analysis method. Results showed that applying the merit system in recruitment and replacement, including mutation and promotion, significantly affects sustainable development. Keywords: recruitment, replacement, regional apparatus performance, sustainable development

Abstract

To overcome the occurrence of an energy crisis in the future, an innovation / invention of energy that is environmentally friendly and energy sources will not run out in the future. Energy sources that are environmentally friendly and their potential when developed is very large, one of which is energy sources derived from wind energy. This study aims to determine the effect of wind speed on the performance of wind turbines. To find out the performance characteristics of wind turbines with variations in air gaps. The research method begins with the design / design of the wind turbine, then continues the manufacturing stage, the assembling and installation stage, the testing of tools and analysis, the tests carried out include testing the performance characteristics of the wind turbine. The parameters measured in this study are rotation, torque as well as calculating the kinetic power produced, TSR and CP. The test results conducted showed that the 200 mm air gap Savonius wind turbine with a value of CP = 0.02480-0.15658 had optimum work at low wind speeds (4 m / s). Meanwhile, the 170 mm airborne Savonius wind turbine with a value of CP = 0.00593-0.14668 has optimum work at high wind speeds (8 m / s to 9 m / s). Keywords- wind turbine savonius, air gap, coefficent of power.
