THE CONSTRUCTION OF A BIOECONOMIC MODEL OF THE INDONESIAN FLYING FISH FISHERY

The high price of flying fish eggs in Japan encourages South Sulawesi fishermen in Indonesia to harvest increasing quantities of eggs every year. Similarly, the increasing local demand for flying fish encourages Indonesian fishermen to use gill nets to catch more fish. As a consequence of this increasing quantity of eggs harvested and fish caught, Indonesia has become concerned about the overexploitation of the flying fish population. Thus far policy suggestions concerning the management of the flying fish fishery have been based on a static biological model, since the data needed to construct a dynamic bioeconomic model are very limited. This paper presents a method for constructing a dynamic bioeconomic model of the Indonesian flying fish fishery with very limited data on the fish population. A calibration technique is developed to build the dynamic biological model.Resource /Energy Economics and Policy,

The Economy-wide Impact of Controlling Energy Consumption in Indonesia: An Analysis Using a Social Accounting Matrix Framework

Escalating oil prices and the need to control carbon emissions sound the alarm for Indonesia to reduce or be more efficient in its energy use. To create an incentive for society to be more energy efficient, the government needs to reduce the current energy subsidy, which, in any case, has imposed a tremendous fiscal burden on the country. This paper aims to analyse the impact on the economy of energy policies aiming to reduce and to improve the efficiency of energy use, particularly on the income of various household groups. This paper will, first, construct a Social Accounting Matrix for Indonesia with detailed energy sectors and, second, utilise various multiplier analyses to observe and understand the impact of these energy policies.Social Accounting Matrix, Energy, Indonesia

Assessing the Value of Clean Air in a Developing Country: A Hedonic Price Analysis of the Jakarta Housing Market, Indonesia

This paper is motivated by the common argument that clean air is a luxury good and has much less or even no value in a less developed country. It applies a hedonic property value analysis, a method commonly used to infer the value of clean air in developed countries, using a combination of data on house values and their characteristics from the Indonesian Family Life Survey, and data of the ambient level of six different pollutants in Jakarta, Indonesia. The result suggests that air quality may affect property value in Jakarta, indicating a preference toward environmental amenities. Moreover, this study is one of the first hedonic studies that may potentially give comparable estimates of the value of clean air in developing countries.Hedonic Prices, Air Pollution, Indonesia

PENGARUH TOOL PLUNGE DEPTH DAN PREHEAT TERHADAP SIFAT MEKANIK SAMBUNGAN FRICTION STIR WELDING POLYAMIDE

Friction stir welding adalah pengelasan dengan memanfaatkan panas yang ditimbulkan oleh gesekan antara material benda kerja dan pin. Pengelasan Friction Stir Welding memiliki beberapa parameter antara lain kecepatan putaran tool, kecepatan pengelasan, tool plunge depth. Penelitian ini bertujuan untuk mengetahui pengaruh tool plunge depth dan preheat terhadap kekuatan mekanik material polyamide hasil las friction stir welding. Tool plunge depth yang digunakan dalam penelitian ini adalah 5,6 mm; 5,65 mm; 5,7 mm; 5,75 mm. Parameter yang dijaga tetap konstan yaitu kecepatan putar tool 620 rpm, kecepatan pengelasan 7,3 mm/menit dan sudut kemiringan tool 20. Kekuatan tarik dan bending maksimal didapatkan pada kedalaman tool 5,7 mm dengan preheat. Optimalisasi kedalaman tool dan preheat akan menjadikan proses pengadukan menjadi lebih baik, sehingga material leleh dapat menyebar diseluruh daerah lasan. Penyebaran material leleh yang merata akan meminimalisir terjadinya void atau cacat yang muncul pada daerah lasan sehingga sifat mekanik dari sambungan semakin meningkat.
