Abstract

Usaha budidaya kerang mutiara lebih banyak terarah pada kegiatan pembesaran dan produksi mutiara, sehingga kebutuhan akan spat sebagai bahan baku utama semakin meningkat. Penelitian telah dilakukan pada bulan oktober 2017 di Laboratorium Balai Pengembangan Perikanan Pantai Sekotong Lombok Barat menggunakan metoda eksperimen.Tujuan Penelitian ini adalah untuk mengetahui perbandingan kerapatan media kolektor yang berbeda terhadap proses penempelan yang lebih efektif pada larva tiram mutiara fase plantygrade di laboratorium. Hasil yang di peroleh pada perlakuan P2 Media substrat/kolektor kerapatan 80% sangat baik dan cukup padat yaitu sebanyak 370 ekor spat/substrat. Sedangkan penempelan spat terendah ditemukan pada perlakuan P1 Media kolektor kerapatan 50% sebanyak 217 ekor spat/substrat. Dapat disimpulkan bahwa semakin lebar kerapatan media kolektor maka semakin kecil proses penempelan larva fase plantygrade. Berdasarkan analisis statistik bahwa kerapatan 50% perlakuan P1 dan perlakuan P2 menunjukan adanyan berbeda nyata, dimana Thitung (1,561) < Ttabel (2.228) ini berarti penempelan larva menggunakan substrat/kolektor kerapatan 50% dengan 80% yang berbeda tetapi tidak berpengaruh pada penempelan larva tiram mutiara fase plantygrade. Hasil pengamatan nilai rata-rata kualitas perairan seperti; Suhu 28,9 0C, pH 7,1, Salinitas 33 ppt, dan DO 5,9  ppm. Pemberian jenis pakan alami terhadap tiram mutiara pada fase plantygrade antara lain yaitu fitoplankton jenis  Isochrysis galbana, Chaetoceros simplex dan Nannoclhoropsis sp.

Abstract

The purpose of this study was to determine the number of catches obtained when caught during the day and caught at night, to determine the most effective composition of catches during the day and at night from the Mini Purse Seine Fishing Gear. This research was conducted in Pondok Prasi Environment, Ampenan District, Mataram City for 1 (month) starting from October 1 to November 1, 2013. The method used in this research is the Experimental Method, namely conducting experiments to see a result that leads to affirmation of the position cause and effect between the variables to be observed. Based on statistical analysis using the Ttest test at the 5% level (0.05) it can be seen that the total weight of the catch (kg) in treatment X1 (during the day) and treatment X2 (at night) showed a significant difference, where Thit (2, 93) > Ttab (2.048) this means fishing using a mini purse seine fishing gear which is operated during the day and at night gives different catches but has no effect on the type of fish caught

Abstract

The South Halmahera Islands feature a comprehensive marine coastal ecology. The ecosystems found were seagrass, mangrove and coral reef ecosystems. The components that sustain the existence of this ecosystem are employed equitably because of its geographical location on the equator. Mangrove ecosystems that provide benefits directly and indirectly to the community. The purpose of this study was to determine the condition of the mangrove ecosystem based on the hemispherical photography method and the type of zonation. Tawabi Island, Kayoa, South Halmahera Regency served as the site of the equator research. The research station is determined as many as 3 stations. Mangrove percent cover canopy using the hemispherical photography and transect quadrant for density. Field data gathering procedures with transects drawn perpendicular from the sea to the land. Zonation characteristics and thickness using zone tracking. Density mangrove using ecology analysis and zonation using canvas 9.0. The results of the research founded were Rhizophora apiculata, Rhizophora mucronata and Sonneratia alba. Mangrove percent cover canopy were good category (75-81%), where station I (75%), station II (81%) and station III (77%). Station I having 600 trees per ha, station II having 500 trees per ha, and station III having 400 trees per ha (low density category). Mangroves were found in 3 zones Sonneratia alba, Rhizophora apiculata and Rhizophora mucronata.

Abstract

The aim of this research is to determine the effective depth in fishing activities and to determine the number and type of fish caught using fish traps. This research was carried out in the waters of Tanjung Luar Village, East Lombok Regency for 1 (one) month. This research used an experimental method with the experimental design used being a Completely Randomized Design (CRD), then continued with the Least Significant Difference (LSL) test at 5% and 1% levels. The factors observed in this study were 3 (three) different depths, namely depth A: 7 m, depth B: 9 m and depth C: 11 m. The results of research on the main parameters show that depth A (7 m) gets the most catches, namely 11.9 kg, then in second place is depth B (9 m) with a catch of 7.7 kg, and the lowest catch is depth C (11 m) as much as 4.3 kg. Water brightness ranged from 6.10 – 8.90 m, current speed ranged from 10 – 15 cm, salinity ranged from 27 – 29 ppt, temperature ranged from 29-30oC, the water at the research location was flat. -an average of 12.5 m and the bottom of the waters is sandy and slightly rocky. The results of the Variety Scan Analysis of the number of fish catches were 52.36, and the Ftable value at the 5% level was 4.26 while the Ftable value was 8.02. So there are real differences between each research treatment

Abstract

This study used a concrete tank to analyze the interaction between different fertilizers and depths in C. racemose seaweed rearing. This study was experimental, using a factorial Completely Randomized Design (CRD) consisting of 2 factors, namely fertilizer (P) and depth (K). The fertilizers consisted of NPK (P1) and sap (P2), and the depths (K) consisted of 5 cm (K1), 10 cm (K2), and 15 cm (K3). Each treatment was repeated 3 times, so we had 18 combined treatments. The study was done at the Cultivation Laboratory of the National Innovation Research Agency (BRIN), Lombok, Indonesia. Research procedures included preparing material and tools, rearing C. racemosa, and harvesting C. racemosa. Research parameters included final weight, final length, specific decline rate, and survival rate. Data were analyzed using ANOVA. The results showed that the interaction of different fertilizers and depths affected the final weight, specific decline rate, and survival rate of C. racemosa. Meanwhile, the final length of C. racemosa was only influenced by different fertilizers. The best treatment happened in the interaction of NPK fertilizer and a depth of 15 cm, which gave a survival rate of 89%, a final weight of 88.66 g, and a specific decline rate of -10.67%/day
