Abstract

Ekosistem terumbu karang Pulau Lembongan memiliki nilai sangat penting bagi kehidupan masyarakat. Pemanfaatan terdiri dari kegiatan: perikanan tangkap; budidaya perairan; perhubungan; dan pariwisata. Tingginya pemanfaatan kawasan terumbu karang dapat menurunkan daya dukung lingkungan. Beberapa indikator ke arah penurunan kualitas dan kuantitas terumbu karang adalah: 1. Pemanfaatan kawasan terumbu karang yang berlebihan; 2. Kegiatan pariwisata yang tidak ramah lingkungan; 3. Kegiatan investasi yang tidak sehat; dan 4. Perebutan kawasan pesisir antar stakeholder. Penelitian bertujuan untuk mengetahui persepsi dan partisipasi masyarakat dalam pengelolaan kawasan terumbu karang. Penelitian dilakukan dengan penyebaran kuisioner dan wawancara. Penelitian menunjukkan masyarakat Pulau Lembongan menyadari terumbu karang memberikan manfaat terhadap kehidupan seperti: terumbu karang sebagai rumah ikan dan karang berfungsi memecah gelombang. Persepsi masyarakat terhadap kondisi karang 10 tahun yang lalu dengan sekarang adalah terjadinya penurunan dalam kuantitas dan kualitas. Tingkat pastisipasi masyarakat dalam pengelolaan lingkungan dalam kategori tinggi, dimana: 1) masyarakat menyatakan siap melakukan upaya pelestarian lingkungan; dan 2) masyarakat ingin terlibat aktif dalam pelestarian lingkungan. Hal ini menunjukkan masyarakat menyadari ada kaitan antara karang dengan kehidupan masyarakat.Kata kunci: terumbu karang, masyarakat Pulau Lembongan, persepsi dan partisipasi

Abstract

This study aimed to examine the effect of the intensity of LED light on the survival rate of Cantang grouper larva in indoor cultivation, and the intensity of LED light on the growth rate of Cantang grouper larva in indoor cultivation. This research is an experimental research type. The subjects in this study were Cantang grouper larva in Penyabangan Village, Buleleng Regency using microscopic observations which were analyzed descriptively and recorded in the table. The data analysis technique used in this study uses SPSS Windows version 21 by using the normality test, the Kruskal walls test and the post hoc test. The results of this study indicate that the intensity of LED light affects the survival rate, this can be seen from Pool 3 filled with 2,000 LUV LEDs which has the highest SR level, which is 5%. The intensity of the LED light affects the growth of the larva studied by using the parameters of length and the percentage of feed consumed in the larva's stomach. This is indicated by the length and the highest percentage of fish larva belly in pond 3 which was treated with 2,000 LUX LED.

Abstract

Pantai Penimbangan terletak Desa Baktiseraga, Kecamatan Buleleng merupakan kawasan pusat kota Kabupaten Buleleng, Bali yang memiliki hamparan pasir hitam. Kegiatan konservasi penyu di kawasan ini meningkatkan gairah masyarakat dalam menjaga kelestarian ekosistem terumbu karang. Salah satu biota yang beriteraksi di ekosistem terumbu karang adalah nudibranch. Keberadaan nudibranch di Pantai Penimbangan diharapkan mampu menjadi alternatif potensi wisata yang bisa dikembangkan, sehingga antusiasisme masyarakat untuk menjaga kelestarian ekosistem pesisir akan terus terjaga.  Penelitian bertujuan untuk memperkuat data dasar ekologi tentang keanekaragaman dan kelimpahan nudibranch. Penelitian populasi nudibranch dinilai dengan sensus visual mengikuti line intercept transect. Penelitian nudibranch di Pantai Penimbangan menunjukkan bahwa terdapat 12 famili yaitu  Chromodorididae, Phyllidiidae, Discodorididae, Aeolidiidae, Elysiidae, Aglajidae, Bornellidae, Facelinidae, Flabellinidae, Hexabranchidae, Limapontiidae, dan Pleurobranchidae, dengan 42 jenis. Kelompok Chromodorididae dan Phyllidiidae adalah kelompok yang umum dijumpai di Perairan Pantai Penimbangan.  Kedua kelompok ini memanfaatkan patahan karang yang menjadi subsrat perairan sebagai tempat berlindung. Komposisi substrat sangat menentukan kekayaan nudibranch, kategori substrat yang menentukan keberadaan nudibranch adalah dead coal with alga, sponge, dan hard coral. Tingginya persentase dead coral with alga, dan sponge berbanding lurus dengan keanekaragaman nudibranch, dan hard coral berbanding terbalik dengan keanekaragaman nudibranch.  Kriteria indeks keanekaragaman tinggi dengan nilai 2,6199, Indeks keseragaman 0,7055 dan nilai dominansi 0,0342.  Tingkat kelimpahan tertinggi pada jenis Hypselodoris tryoni. Penimbangan Beach is located in Baktiseraga Village, Buleleng District, which is the downtown area of Buleleng Regency, Bali which has a stretch of black sand. Turtle conservation activities in this area increase the enthusiasm of the community in preserving the coral reef ecosystem. One of the biota that interacts in the coral reef ecosystem is the nudibranch. The existence of nudibranchs at Penimbangan Beach is expected to be an alternative tourism potential that can be developed, so that public enthusiasm for preserving coastal ecosystems will continue to be maintained. This study aims to strengthen the basic ecological data on the diversity and abundance of nudibranchs. The study of the nudibranch population was assessed by visual census following the line intercept transect. Research on nudibranchs at Penimbangan Beach showed that there were 12 families namely Chromodorididae, Phyllidiidae, Discodorididae, Aeolidiidae, Elysiidae, Aglajidae, Bornellidae, Facelinidae, Flabellinidae, Hexabranchidae, Limapontiidae, and Pleurobranchidae, with 42 species. Chromodorididae and Phyllidiidae groups are common groups found in Penimbangan Beach. Both of these groups take advantage of coral fractures which become the substrate of the waters as a shelter. Substrate composition greatly determines the richness of nudibranchs, the substrate categories that determine the presence of nudibranchs are dead coral with algae, sponges, and hard corals. The high percentage of dead coal with algae, and sponges is directly proportional to nudibranch diversity, and hard coral is inversely proportional to nudibranch diversity. The criteria for the high diversity index are 2.6199, the uniformity index is 0.7055 and the dominance value is 0.0342. The highest abundance level was in Hypselodoris tryoni.

Abstract

Artificial live rock is an artificial live rock that is shaped like living rock in nature. Artificial live rock is designed to mimic natural living rock which is capable of being a substrate for corals, a habitat for epibenthic and the biological filter of a saltwater aquarium.  The purpose of this research is to know the technique of making artificial live rock and the development of artificial live rock that are suitable for export on an export scale. The method used in this research is an experimental method with quantitative descriptive analysis. The level of suitability and product standards uses a simultaneous regression coefficient test analysis or the F test.  The manufacture of artificial live rock does not have a special pattern, but artificial live rock is made as attractive as possible and resembles the shape in nature. Product standardization is carried out by using artificial live rock materials consisting of: 1 kg of pumice stone, ½ kg of cement, ½ kg of sand, 500 grams of calcium and 1.5 liters of water. The type of substrate that is good and ideal for algae on the surface of artificial live rock is an area with a bottom of coral sand mixed with coral rubble. Artificial live rock can be harvested for 3 months in water, with the characteristics of the surface of the artificial live rock covered algae which is then cleaned and placed in a treatment pond before being exported

Abstract

The purpose of this research was to identify heavy metals in Jembrana waters and analyze water quality to determine water fertility. This study used direct observation and quantitative descriptive. Primary production, biological chemical physical parameters, and heavy metal data were collected in this study. The results showed that Jembrana waters had the highest primary productivity value of 1051.01 mgC/m3/day and the lowest value of 112.61 mgC/m3/day. Water quality in Jembrana is considered quite good. The results of this study showed that the water conditions at the observation site remained stable and within the tolerance limits for marine biota. This is due to the fact that during the sampling period, there was no significant activity from fishermen and local residents. Observations of heavy metals lead and cadmium at the study site showed that some stations exhibited values that exceeded the threshold, but these values were still acceptable for the waters. The heavy metal levels at the stations exceeded the threshold due to sewage effluents from companies and ships in the local harbor.
