Abstract

The aims of this research was to know the development of egg diameter ofclimbing perch were feed enriched used different dosage of vitamin E. The experimentwas arrenged in a Completely Randomized Design (CRD) with 5 treatments and 3replicated. The treatments was vitamin E (V.E) consist of, V.E0 (0 mg.kg-1) withoutvitamin E, V.E1 (100 mg.kg-1), V.E2 (150 mg.kg-1), V.E3 (200 mg.kg-1), V.E4 (250mg.kg-1) of feed. Parameters observed consist of eggs diameter development, gonadmaturity levels and water quality. The results of study showed that the enrichment of150 mg.kg-1 vitamin E on feed was provided response on the development of the eggdiameter (0.401 mm) and reached gonad spawned stage that showed by the transparantcolour of eggs (mature). Water quality parameter during rearing was still in tolerantrange of climbing perch.

Abstract

A study was conducted to induced triploidy in fertilized egg of sheatfishlarvae , (Kryptopterus lympok) using heat shock. The eggs were exposed at 40OCfor shock duration of 1 , 3 , 5 and 0 minutes as a diploid control. Results showedthat the 5 minutes shock duration was the highest triploid induction and yield(91.7 and 62.9%). Erythrocyte analysis showed that the volume of triploid fishgroup was bigger that that of diploid one. The fertilization, hatching and survivalrate was lower in triploid groups, while SGR was higher compared to diploid fish.

Abstract

Penelitian ini dilakukan pada bulan Oktober 2018 di Perairan Pantai Rangsang Barat, Kabupaten Kepulauan Meranti, Provinsi Riau. Penelitian ini bertujuan untuk mengetahui perubahan garis pantai yang  terjadi di Kecamatan Rangsang Barat dalam rentang waktu 10 tahun terakhir dan implementasi hukum laut tentang pengaturan permasalahan perubahan garis pantai di Kecamatan Rangsang Barat Kabupaten Kepulauan Meranti Provinsi Riau. Hasil pengolahan citra Landsat 5 dan Landsat 8 dengan besar Perubahan garis pantai di Desa Melai adalah 55,56 m (akresi), di Desa Kedabu Rapat sebanyak 50,94 m (abrasi) dan di Desa Bungur sebesar 42,10 m (abrasi). Implementasi hukum laut menurut pasal 15 UNCLOS 1982 dalam penetapan wilayah laut teritorial yang berdampingan dengan negara lain memutuskan uu no 2 tahun 1971 tentang penetapan batas wilayah kedua negara di Selat Malaka. Penentuan titik koordinat tersebut ditetapkan berdasarkan Garis Pangkal masing-masing negara. Dengan diberlakukannya Konvensi Hukum Laut Internasional 1982 sehingga ditetapkan Peraturan pemerintah Republik Indonesia no 38 tahun 2002 tentang daftar koordinat geografis titik-titik garis pangkal kepulauan Indonesia. Dengan penetapan titik koordinat geografis permasalahan pada perubahan garis pantai negara Indonesia dan Malaysia akibat dari abrasi dan akresi dapat diselasaikan dengan memperhatikan titik koordinat geografis pada pulau Rangsang.

Abstract

Tabingal fish (Puntioplites bulu Blkr) is a type of freshwater fish that commonly inhabit the Siak River, Riau. To understand the sex ratio and condition factor of this fish, a study has been conducted in April to October 2009. Total number of fish collected was 131. The sex ratio of this fish during the research period was almost constant (1:1), but the number of male was slightly higher than that of the female. Most of fish collected were 87-241 mm TL and they are categorized as undeveloped gonad fish. The factor condition was ranged from 1.21-1.50.

Abstract

Pangasianodon hypophthalmus is a type of freshwater fish that has potential and has economic value. Its production target which increases every year causes farmers to spawn with the help of hormonal stimulation. The aimed of this research was to test and find out the results of the use of three different hormones namely Ovaprim, Spawnprim, and HCG in P. hypopthalmus spawning. This research was conducted in January 2020 at the Trimurjo Fish Seed Center, Central Lampung. This research used a randomized complete design method with the 3 treatments, P1 (Ovaprim 0,5 ml / kg), P2 (Spawnprim 0,5 ml / kg), P3 (HCG 500 IU / kg) and 3 replications. The results of this research indicate a significant difference (p <0,05) in the relative fecundity parameters, fertilization rate, and hatching rate, but not significantly different in the parameters of latensi periode and diameter of eggs. In P1, Ovaprim hormone injections provide better reproductive performance compared to Spawnprim and HCG injections.

Abstract

This reseach was conducted in March to April 2012, in Padang Beach ofWest Sumatra and in Integrated Oceanology Lab of Riau University. The aim ofthis research is to reveal the progress of abration happening in Padang Beach. Themethod used in this research is the survey one. The result of this reasearch showsthat abration happened at three research stations, the abration velocity at the firststation is 0,28 m/year, the second is 0,36 m/year and at the third one is 0,12m/year. The principle causes of abration process in Padang beach are the flow andthe great wave of the sea which signed by each characteristic and the flow that thebeach abrased easily, as the bigger of wave's energy and water's flow the faster ofabration will be.

Abstract

Palembang is the capital city of South Sumatra Province which has special foods which main raw material is fish. Many pempek entrepreneurs use cork fish meat for pempek raw material resulting in abundance of cork fish bone waste, therefore researchers utilize cork fish bone waste as an alternative into raw material in making gelatin. In this study, researchers used several weak acids derived from natural ingredients such as lime extract and starfruit extract and as a comparison researchers used synthetic weak acids namely citric acid in the market. The purpose of this research used several types of acids in the demineralization process to produce better gelatin production. This study used a Completely Randomized Design, with several acid treatments with and consisting of 3 (three) treatment levels, each treatment was repeated 3 times. The treatment in this study was a demineralization process with the addition of citric acid was (A1), lime extract was (A2), and starfruit extract was (A3). The parameters examined in this study include: Gelatin yield, Gelatin acidity (pH), Moisture and Sensory content (color and aroma). Data from proximate observations were analyzed by analysis of variance (ANOVA) and further tested based on the coefficient of diversity. From the results of this study, it was found that the best treatment of using variations in acid was gelatin demineralized using citric acid which produced a yield was 6%, a moisture content was 9.21%, pH 6, the panelist's favorite value of color was 4.3 and aroma 3, 8.
