Abstract

Limited land has encouraged the local government to carry out reclamation for the development of coastal areas, taking or transferring the function of coastal protection land. Reclamation has been carried out in every sub-district in Parepare City, such as the construction of an embankment in Soreang District, land expansion and construction of a port area in Ujung District, and the development of beach tourism in West Bacukiki District. Development in coastal areas that are not in accordance with applicable regulations and causes an imbalance sediment transport along the coast.The purpose of this study was to determine changes in the coastline in the Pare-pare Bay area within a period of 20 years using remote sensing satellite imagery data and find out the causes of changes in the coastline in the Pare-pare Bay area.Its use is expected to provide information about changes in the coastline in the City of Pare-pare, in order to assist the local government in making policies in the management of coastal and marine areas in a sustainable manner and also in making spatial plans for the City of Parepare. The method used in this research is to collect spatial data in the form of 2001 Landsat 7 and 2021 Landsat 8 images. The spatial data analysis uses the method of making polygons using measure tools on the resulting map overlay in the GIS application. The results of the study in the Parepare Bay Area concluded that the magnitude of the shoreline change in the Parepare Bay Area within a 20 year period was 22.47 Ha. The length of the coastline has increased by 0.22 km. Changes in the coastline in the Parepare Bay Area are caused by natural factors and human activities. Natural factors in the form of waves, currents and tides. While the factor of human activity in the form of reclamation along the coast of Parepare Bay.

Abstract

Vannamei shrimp cultivation in Indonesia is currently the mainstay of the aquaculture sector and is a priority for aquaculture development in Indonesia to improve the national economy. Pond management in general in Indonesia, especially in Java, still needs better management planning. This can be seen from the many abandoned ponds due to crop failure. Even abandoned ponds on the island of Java reached 70%. This study used a quantitative method by collecting interview data and studying literature. Variables in this study include aquaculture (HR), technology, economic motives. The instrument used in this study was in the form of an interview sheet. and West Java p(T<=t) 0.2. Area of harvested land from Central Java and West Java Provinces with p=0.04 (<0.05). Yields from the provinces of East Java and Central Java with p=0.02 (<0.05). Area of harvested land from East Java and Central Java with p=0.04 (<0.05). Getting to the conclusion that there is a relationship between the area of harvested land and yields in the Provinces of East Java and West Java.

Abstract

Indonesia memiliki potensi yang sangat besar untuk pengembangan budidaya lobster air tawar , jika dilihat dari kondisi alamnya. Lobster air tawar merupakan salah satu jenis crustacea yang memiliki nilai prospek yang cukup bagus didalam sektor perikanan, akan tetapi Dalam pembenihan lobster air tawar terdapat beberapa kendala seperti pengeraman yang relative lama dan tingkat penetasan yang belum optimal. Hal ini dipengaruhi lingkungan yang kurang mendukung Suhu adalah salah satu parameter lingkungan yang berpengaruh signifikan terhadap daya tetas dan perkembangan larva ikan serta suhu dapat menghambat proses pengeraman khususnya pada penetasan telur. Tujuan dari penelitian ini untuk mengetahui pengaruh perbedaan suhu air terhadap derajat penetasan telur dan mengetahui suhu terbaik pada penetasan telur. Penelitian ini menggunakan metode eksperimental dengan rancangan acak lengkap (RAL) dengan 3 perlakuan dan 8 pengulangan. Perlakuan dalam penelitian ini : perlakuan suhu 26 oC, 29 0C, 320 C. data yang diamati daya tetas telur lobster air tawar (C quardicarinatus). Hasil penelitian meunjukkan bahwa perbedaan suhu air berpengaruh nyata terhadap daya tetas telur lobster air tawar. Perlakuan C 32 oC adalah perlakuan terbaik yang menghasilkan lama waktu penetasan 6,6 hari dan perlakuan B 29 0C adalah perlakuan terbaik pada daya tetas telur 91,5 %.

Abstract

Indonesia adalah suatu negara Kepulauan dan bahkan menjadi salah satu negara dengan kepualuan terbesar didunia. Rumah tangga nelayan biasanya mempunyai persoalan yang lebih rumit dibandingkan dengan rumah tangga pertanian. Ciri-ciri yang dimiliki rumah tangga nelayan terkhususnya seperti penggunaan wilayah pesisir dan lautan sebagai faktor produksi, adanya ketidakpastian penghasilan, jam kerja yang harus mengikuti siklus bulan yang biasanya dalam satu bulan hanya bisa bekerja selama 20 hari sisanya mereka hanya menganggur. tujuan dari penelitian ini adalah untuk mengetahui faktor penghambat dalam mewujudkan kesejahteraan rumah tangga nelayan di TPI Cempae Kota Parepare Sulawesi Selatan.kemiskinan sebagai keterbatasannya dalam bidang pendidikan. Menurutnya “kemiskinan dicirikan oleh rendahnya kesadaran masyarakat untuk melanjutkan pendidikannya, rendahnya tingkat pendidikan keluarga nelayan sehingga tidak memiliki kemampuan dan pengetahuan yang cukup untuk diterima dan memenuhi syarat bekerja disektor lain yang memiliki penghasilan lebih banyak”. Dan ada yang memahami kemiskinan sebagai ketidak mampuan dalam mencukupi kebutuhan pokok, yaitu sandang, pangan dan papan. faktor penyebab kemiskinan berupa fluktuasi musim tangkap, sumberdaya manusia nelayan, ekploitasi pemodalBerdasarkan dari hasil penelitian dapat disimpulkan bahwa, faktor yang mempengaruhi tingkat kesejahteraan nelayan di TPI Cempae Kota Parepare dipengaruhi oleh beberapa faktor seperti: Fluktuasi Musim Tangkap, Sumberdaya manusia nelayan, Ekploitasi Pemodal. Sehingga para istri nelayan harus ikut membantu dalam mencukupi kebutuhan ekonomi keluarga mereka, dengan cara bekerja sesuai dengan kemampuannya.

Abstract

Viral Nervous Necrosis (VNN) disease is one of the diseases included in the list of aquatic animal diseases of the World Organization for Animal Health (WOAH) and is a pathogen that poses a threat to grouper aquaculture throughout the world. VNN infection can occur vertically and horizontally and has a mortality rate of up to 100%. This study aimed to detect VNN using molecular methods (PCR) in grouper cultured in Buleleng, Bali. The method used is molecularly by conventional PCR. The results of this study indicated that groupers with VNN showed rotating, solitary swimming and enlarged eyelets (exophthalmos). The internal organs show enlargement of the spleen and kidneys. The liver looks pale and haemorrhage occurs in other internal organs. The results of the PCR examination showed 5 (five) positive samples of VNN with the appearance of a band at 230 bp so that the prevalence of VNN was 25%. From the results of this study, recommendations that can be taken are monitoring and surveillance of VNN need to be carried out continuously in grouper aquaculture, this is necessary to determine actions to be taken quickly if VNN is detected in an aquaculture unit. Keywords: betanodavirus grouper, molecular, PCR, VNN
