Penggunaan Light Emitting Diode Pada Lampu Celup Bagan (the Use of Light Emitting Diode on Sunked Lamps of Lift Net)

Lift net fishermen usually use fluorescent lamp as attractor to lure fish. As price of fuel rise, fishermen are forced to find another option to change their attractor into some much lower cost and more energy-save lamp, or in other words, to change into LED lamp. This research are providing evidence that sunked LED lamps can be utilized as a helper tools, and also determined the best time for catching fish in the lift net. Two lift net used in this research, one of them used sunked LED lamps and the other used ordinary fluorescent lamps. Lift net are operated as long as 20 nights, with four catching times per night, between 18.00-21.00, 21.00-00.00, 00.00-03.00, and 03.00-06.00. Results showed that LED lamps give a better result with 11 organisms successfully catch (287,6 kg), compared to ordinary fluorescent lamps with only six organisms (238,3 kg). The best time for catching with LED lamps are between 18.00-21.00 (121 kg), while between 21.00-00.00 (67,4 kg), 00.00-03.00 (46,9 kg) and 03.00-06.00 (52,3 kg)

Penguatan Cahaya Pada Bagan Menggunakan Reflektor Kerucut Sebagai Upaya Meningkatkan Hasil Tangkapan Cumi-cumi (Light Strengthening on Lift Net with Conical Reflectors to Squid Catch Improvement)

Study of light strengthening on lift net with conical reflectors was conducted in Kao Bay waters. Three units of lift net were operated 14 nights at the full moon condition. Every lift nets were completed with three different kind of lamp cover, called tudung, reflector αr23,3o and αr32,6o. Fishing operation time of lift net were divided into two intervals of time i.e 20.00-01.00 and 01.00-05.00 WIT (East Indonesian Timezone). Total yield of lift net with reflector αr23,3o was 5.774 kg (41,45%), while that of the lift net with reflector αr 32,6o was 4.977 kg (35,72%), and that of total yield of the lift net with tudung was 3.180 kg (22,83 %). Fishing operation time of lift net at 01.00-05.00 WIT (East Indonesian Timezone) produced 12.661 kg (91 %) weight of total catch, higher than fishing operation of lift net at 20.00-01.00 am that produced 1.270 kg (9 %) weight of total catch. However, statistical analysis concluded that design of the reflector did not significantly affect the catch per trip (Pvalue > 0,05) while fishing time significantly affected the catch per trip (Pvalue < 0,05)

FORECASTING PRODUKSI HASIL TANGKAPAN IKAN MANYUNG DI PELABUHAN PERIKANAN NUSANTARA KEJAWANAN, KOTA CIREBON

Produksi ikan manyung di Pelabuhan Perikanan Nusantara (PPN) Kejawanan cenderung tidak menentu, sementara banyak industri pengolahan dan pasar ikan asin yang membutuhkan pasokan ikan manyung. Penelitian bertujuan mengidentifikasi kondisi produksi dan armada penangkapan ikan manyung, serta menentukan model forecasting yang tepat untuk prediksi produksi hasil tangkapan ikan manyung. Metode yang digunakan adalah metode deskriptif, model moving average dan model exponential smoothing. Rata-rata produksi ikan manyung di PPN Kejawanan dalam 15 tahun terakhir mencapai 40,72 ton per tahun. Armada penangkapan ikan manyung di PPN Kejawanan adalah armada bouke ami, purse seine, gill net oseanic, cast net dan pancing cumi. Armada bouke ami merupakan yang paling banyak digunakan dengan rasio trip penangkapan mencapai 72%. Model exponential smoothing α=0,3 merupakan model yang paling tepat untuk mempredikasi produksi hasil tangkapan ikan manyung di PPN Kejawanan. Setelah divalidasi, hasil prediksi model tersebut terhadap produksi ikan manyung adalah 45,26 ton untuk 2020, 31,68 ton untuk tahun 2021, 43.22 ton untuk tahun 2023, dan 56,04 ton untuk tahun 2024.

A two-part study on the alternative exchange of South Africa (AltX) : a study on the underpricing of new equity issues listed on the alternative exchange of South Africa and the effects of specific use of disclosure on underpricing

Includes bibliographical references (leaves107-113).Extensive research has been conducted in a variety of countries investigating the extent of underpricing of initially listed companies. In addition, various studies have been conducted in an attempt to try and establish the relationship between disclosure and underpricing. Underpricing remains a vexing issue that continues to stimulate rigorous debate within economic and accounting research. This study seeks to remedy the omission of recent South African research on this subject. The study looks to establish whether underpricing has occurred on the Alternative Exchange of South Africa, (AltX). The AltX was launched on 27 October 2003, as the junior exchange to the larger Johannesburg Stock Exchange (JSE). The study follows the methodology of a previous South African study, by Barlow and Sparks (1986), which looked at the underpricing of shares on the JSE between the periods 1972 to 1986. This study looks at establishing underpricing on the AltX, during the periods October 2003 to March 2007
