Abstract

Fishery products generally spoil more quickly than other animal meat products. After being caught, fish will experience changes in quality, the level of these changes will determine the shelf life of the fish. Handling fresh fish is the most important aspect of a fisheries business. Cold storage is a way of storing fish at a certain temperature which allows fresh fish to be stored for long periods, even months, to prevent bacterial growth. This research aims to evaluate the implementation of the Standard Operating Procedure (SOP) for storing fish in cold storage using the First In First Out (FIFO) system and to evaluate the quality of the cooling system using temperature and humidity monitoring at Jaya Bahari cold storage. The method used in this research is measurement, interviews and literature study. The process stages in receiving fish products start from unloading fish, thawing frozen fish, weighing and testing samples, sorting and calculating the percentage of rejects, as well as temporary storage by looking at various obstacles during the process of receiving raw materials. The performance of the data logger and big data each showed results that were not much different with the respective tool accuracy values of 99.26% for temperature measurements and 99.83% for humidity measurements. Defrosting ice for 2 hours can save power by 4.37%.

Abstract

The city of Surabaya has a fairly high Human Development Index, but inequality still exists for marginalized communities such as fishermen on the north and east coasts of Surabaya. Indonesian Traditional Fishermen have an important role in the macro economy and national food security. Traditional Fishers are still included in a marginalized group of people who are very vulnerable to natural and political factors. Efforts to increase the resilience of fishermen need to be carried out by maximizing the assets/capital in the community. The purpose of this study was to assess the livelihood achievement index of fishermen on the dimensions of financial, natural, social and human capital with a case study conducted at the Fishers’ Cooperative Bahari 64 community. Using a quantitative descriptive method, this study conducted a survey of 98 respondents from 130 members who work as a fisherman. From the data analysis it was found that the fishing community of Koperasi Bahari 64 was categorized at a good level with a livelihood index value of 62.26 with an achievement dimension of 62%.

Abstract

Tradisi petik laut sering juga disebut dengan larung sesaji yang dikaitkan dengan syukuran para nelayan atas segala hal yang telah diberikan oleh laut. Saat ini petik laut telah mengalami transformasi menjadi ajang pesta rakyat, namun sejatinya ritual petik laut ini merupakan ekspresi spiritualitas komunitas nelayan pesisir di Jawa dan Madura. Untuk menjaga salah satu kearifan lokal tersebut maka perlu dilakukan kajian yang komprehensif mengenai tradisi petik laut dalam tinjauan sains dan Islam. Secara spesifik, penelitian ini bertujuan untuk mengetahui pengaruh bacaan Al-Quran pada pertumbuhan mikroorganisme atau bakteri air laut. Hal ini dikarenakan mikroorganisme atau bakteri merupakan salah satu aktor yang berperan penting dalam sistem kelautan yang selanjutnya akan mempengaruhi produktivitas perairan dan hasil tangkap. Pengambilan sampel air laut yang digunakan dalam penelitian ini adalah air laut di pesisir Sidoarjo. Sampel diambil pada permukaan air laut sejauh 100 meter dari bibir pantai dan dilakukan sekali untuk semua sampel. Analisa pertumbuhan mikroorganisme air laut dilakukan di laboratorium mikrobiologi. Perlakuan yang diberikan adalah dibacakan (1) surat an-Nahl, (2) al-Fatihah, dan (3) tanpa perlakuan (kontrol). Sampel pengontrol (pre-test/baseline) dan sesudah perlakuan (post test) ditumbuhkan dalam media NA dengan teknik Total Plate Count (TPC) di laboratorium. Penghitungan jumlah bakteri dengan menggunakan colony counter dilakukan setelah diinkubasi selama 24 jam. Data hasil pengamatan jumlah koloni bakteri akan diuji dengan dengan menggunakan dua variabel yaitu perlakuan dan hari. Hasil analisa statistik dengan menggunakan analisis non-parametrik uji Friedman menunjukkan bahwa besaran nilai Chi Square = 30.545 dan asymp sig sebesar 0.000. Hasil tersebut menunjukkan bahwa ketiga perlakuan (dibacakan surat an-Nahl, al-Fatihah dan tanpa perlakuan (kontrol)) memberikan reaksi yang berbeda dengan jumlah nilai TPC atau pertambahan koloni bakteri air laut.
