The study of biodiversity is important in looking at the current condition of an aquatic environment. The purpose of this study is to examine the biodiversity of the fauna in the Progo River in determining the level of fish diversity and the status of fish resources in the Progo river by using a Geographical Information System (GIS). The sampling method was carried out by purposive sampling consisting of 17 stations. The data taken includes coordinate points, the diversity index (H '), evenness index (E), dominance index (D), and relative abundance (Kr), as well as making a map of the distribution of progo river fish using Arcgis software version 10.5. The results showed that the diversity index value (H ') was moderate to high with a value range of 2.24 to 3.83, with a catch composition consisting of 23 species and 11 families. The evenness index value (E) of the progo river ranges from 0.71 to 1.21. Based on this value, the Progo River has an evenness value between species that is relatively even or the number of individuals of each species is relatively the same. Progo river dominance index value ranges from 0.002-0.008, that is, no fish species dominates. The highest relative abundance (Kr) was balar fish (Barbonymus balleroides) = 0.12%, melem fish (Osteochilus vittatus) = 0.11%, uceng fish (Nemacheilus fasciatus) 0.09%, tilapia fish (Oreochromis niloticus) 0 , 08%, while the lowest was kekel fish (Glyptothorax platypogon) and sepat fish (Trichopodus trichopterus) with a value of 0.01%. The results of the analysis of the distribution of fish in the Progo river show that the fish are widely distributed in the river area which has deep and calm water characteristics, this is indicated by the number of catches at each research station.Keywords: Biodiversity, Progo River, Geographical Information System (GIS)

Guppy fish is currently in high demand because they has interesting color variations such as red, blue, yellow. The carotenoid content in red peppers and red spinach is able to increase the brightness of the color of the fish. This research aims to find out the effect of the addition of red peppers and red spinach on guppy fish color. Completely Randomized Design with 3 treatment and 3 repetitions was used. The research data was analyzed by using the Adope Photoshop app by observing the discoloration that occurred before and after the treatment by using color libraries. The study found that the percentage of blue and purple in guppy fish increased. This was related to the absence of carotene that associated with protein and produces carotenoproteins. The most prominent discoloration result was the treatment 1 (addition of peppers). In treatment 1 there was a significant discoloration of the blue color with the code 732-0 from 0% to 11.9%, while in the treatment 2 (addition of spinach) color coded 732-0 was changed from 0% to 5.88%, the treatment 3(control) treatment was changed from 1.21 % to 0.6%. Meanwhile, the purple color with the code 728-0 on treatment 1 from 0% to 2.36%, on treatment 2 from 0% to 0.22% and on treatment 3 purple color did not came out. It can be concluded that the most influential to the color of guppy fish was peppers, spinach and control treatment, respectively.Keywords : red spinach, carotene, guppy fish, red peppers, color.

Petik laut adalah tradisi kebudayaan masyarakat nelayan di pesisir Jembrana, Bali. Tujuan dari penelitian ini adalah untuk mengetahui pola perbedaan pelaksanaan tradisi petik laut antara nelayan yang beragama Hindu dan nelayan yang beragama Islam di Jembrana Bali serta pola kebijakan di wilayah pesisir yang dapat dibuat berdasarkan adanya akulturasi budaya tersebut. Metode penelitian yang digunakan dalam penelitian ini adalah deskriptif kualitatif dengan teknik pengambilan data berdasarkan wawancara mendalam (deep interview) dan pemberian kuesioner kepada 20 responden. Hasil penelitian menunjukkan bahwa penerapan tradisi petik laut oleh nelayan yang beragama Hindu dan nelayan yang beragama Islam adalah mirip. Nelayan Hindu melaksanakan tradisi petik laut berdasarkan pada keyakinan pancasradha selama 3 hari yang berlandaskan pada tattwa, susila, dan upacara. Nelayan Islam melaksanakan tradisi petik laut didasarkan keyakinan iman kepada Tuhan selama 3 hari yang diiringi dengan pembuatan larung sesaji. Tradisi petik laut merupakan hasil akulturasi budaya yang ada sejak zaman nenek moyang sebagai cara bersyukur dan memohon berkah kepada Tuhan. Hasil penelitian menyimpulkan bahwa pola pelaksanaan tradisi petik laut antara nelayan yang beragama Hindu dan Islam terletak dari pada teknis pelaksanaan tradisi yang akan memberikan corak perbedaan. Tradisi petik laut di Jembrana yang berlangsung turun-temurun dapat memberikan fondasi kebijakan berupa (1) sebagai landasan dasar penyusunan peraturan daerah tentang pengelolaan pesisir yang berbasis pada budaya masyarakat, (2) landasan religius tradisi petik laut dapat dijadikan sebagai visi pengelolaan sumber daya pesisir yang lestari, dan (3) tradisi petik laut yang dijalankan oleh agama Hindu dan Islam dapat dijadikan sebagai opsi pengembangan cultural tourisms bagi pemerintah daerah setempat.Title: Implementation of The Petik Laut Tradition on Hindu and Islamic Fishers with Correlation of Coastal Resource Management in Jembrana Petik Laut is a cultural tradition of the fishing community on the coast of Jembrana, Bali.
