Abstract

AbstractGrowth of fish is affected by environmental conditions. As growth pattern is reflected on the growth ring pattern in the otolith, growth pattern variations caused by environmental condition will also be reflected in the growth ring pattern in the otolith. Mudskipper was present in 2 different areas namely in the mangrove ecosystem and around the harbor area.  To understand the growth ring pattern of the fish from those areas, a study has been conducted on August to October 2018.  Fifty seven fishes were captured, 32 fishes (15 males and 17 females, 135-215 mm of TL, 16-185 g of BT) from the mangrove and 25 fishes (9 males and 6 females, 150-230 mm of TL, 35-141 g of BT) from the harbor. The otolith was removed, processed, and growth ring pattern was checked using a binocular microscope. Results shown that dark growth ring pattern in the fish from the harbor and mangrove was different. The mangrove fishes has 1-4 dark growth ring, while the harbor fishes have 2-9 dark growth ring . The quantity of dark ring in otolith shown that the fish from the mangrove grew better than the fishes from the harbor.Keywords :environmental conditions, otolith ring, amphibious fish, growth pattern.

Abstract

AbstractPuntioplites bulu is  a type of freshwater fish that commonly inhabit the Batang Mahat River, Riau. A study aims to understand the reproductive biology of P. bulu has been conducted. The fish was sampled 6 times, second/month, from January to March 2019. Parameters measured were sex ratio, gonad maturity level, gonad somatic index (GSI), fecundity and egg diameter. Results shown that there were 31 males and 34 females (sex ratio 1:1). The male has  slimmer body and brighter color than those of the female. The gonadal matury levels in females was 3 in Batang Mahat River.  The average GSI of fish ranged from 0.26-3.78%. The average fecundity  of the  female   was 179.12-202.57. Egg diameter  ranged from 0.66-1.20 mm, where  the small egg (0.66-0.92 mm) was 83-84%, the medium egg (0.93-1.19) was 14-15% and the large egg >1,20 was 1.67%. Based on the size of egg diameter can be concluded this fish is total spawner.Keywords: Sex ratio, gonad matury level, gonad somatic index, fecundity                   Total spawner

Abstract

In the Delima Village, Pekanbaru City, there is a group of women that used to conduct a household scale fish culture activities. Most of them using a simple earthen pond. They did not apply any modern technique in culturing the fish. To improve the ability of the women community in culturing fish, a dissemination of environmental friendly fish culture technique was conducted. Slides and a simple manual book for conducting manipulated photoperiod in fish culture was used during the training. The community were also trained to construct tarp ponds, feeding, rearing Pangasius hypopthalmus and managing the water quality in the pond. Twenty five women that were belonged to “PKK” group attended the training. Before the training, their knowledge on fish culture was very low, but after the training, their knowledge improved by 85%. Results of monitoring and evaluation activities shown that the women from the PKK group were able to culture fish with manipulated photoperiod technique.

Abstract

Garam merupakan sumber elektrolit dan iodium yang sangat penting bagi tubuh manusia. Garam konsumsi yang akan beredar ke masyarakat harus memenuhi Standar Nasional Indonesia (SNI). Penjaminan kualitas garam konsumsi beriodium dapat dilakukan dengan analisis kimia. Penelitian ini bertujuan untuk mengetahui kesesuaian standar mutu garam konsumsi beriodium yang akan diedarkan ke masyarakat dengan SNI. Metode penelitian ini berdasarkan SNI 3556:2016 antara lain: (1) Analisis kadar air dengan gravimetri; (2) Analisis bagian yang tidak larut dalam air; (3) Kadar NaCl dengan argentometri; (4) Kadar KIO3 dengan iodometri; (5) Analisis cemaran logam dengan flame atomic absorption spectrophotometry. Penelitian ini dilakukan pada tiga bentuk garam yaitu garam kasar, garam halus, dan garam briket. Kadar air ketiga garam memenuhi syarat dengan nilai di bawah 7%. Bagian yang tidak larut pada garam kasar memenuhi syarat, sedangkan garam halus dan garam briket tidak memenuhi syarat dengan nilai di atas 0,5%. Kadar NaCl ketiga garam tidak memenuhi syarat minimal SNI yaitu 94%. Kadar KIO3 garam kasar tidak memenuhi syarat minimal SNI yaitu 30 mg/kg, sedangkan garam kasar dan briket memenuhi syarat. Cemaran logam Pb dan Cd memenuhi syarat dengan nilai di bawah 10 mg/kg dan 0,5 mg/kg.

Abstract

The morphology and isozyme marker was not enough to reveal banana genetic diversity. So, it needs molecular analysis. The purpose of this research is to know the genetic diversity of banana with B genome using microsatelite marker. Forty bananas with B genom from Yogyakarta Agriculture Service and Animal Husbandary Service and also from Tropical Fruit Centre of Bogor Agriculture Institute were amplified using 6 loci (MaCIR327b, MaCIR108, Ma-3-139, Ma-3-90, Ma-1-17, and Ma-1-27). The diversity were identified with allele amount, genotype, observe heterozigosity, and filogeny. There are eight allele per locus average from six microsatelites. MaCIR108 produced the highest allele amount, there are 13 alleles. The research identified 75 genotypes. MaCIR327b, MaCIR108, Ma-3-139, Ma-3-90, Ma-1-17, and Ma-1-27, respectively, produced 8, 20, 13, 14, 15, and 5 alleles. The Ho average is quite high, there are 0,77. The similarity coefficient is between 0,597 – 1,00. MaCIR108 and Ma-3-90 can be used to identify banana group genom. As a group genom characteristic, Ma-1-17 needs more research. Identification result between morphology and microsatelite marker were different. Based on morphology marker, Sri Wulan and Byar cultivar were ABB, and Ketip Gunung Sari were AAB, but based on microsatelite marker Sri Wulan and Byar cultivar were AAB, while Ketip Gunung Sari has not B on its genom. Keywords: genetic diversity, banana, microsatelit.
