Abstract

Telaah spasio-temporal komunitas ikan padang lamun di perairan pesisir Bontang Kalimantan Timur.. Tujuan dari penelitian ini adalah untuk menganalisis spesies penyusun padang lamun, kondisi padang lamun dan spesies ikan yang penting dalam komunitas pada perairan padang lamun. Ikan tersebut dikumpulkan dengan jaring insang berukuran 1,5 inci, sedangkan vegetasi lamun dikumpulkan dengan metode kuadrat. Hasil penelitian menunjukkan bahwa untuk keanekaragaman habitat dan spesies penyusun padang lamun yang lebih padat, lebih banyak spesies ikan ditemukan berbeda nyata dalam kelimpahan individu, tidak hanya pada lokasi yang berbeda tetapi juga pada periode pengambilan sampel yang berbeda. Indeks struktur jenis menunjukkan bahwa komunitas ikan di padang lamun Kota Bontang mempunyai indeks keanekaragaman Shannon (H’) secara spasial-temporal dan tergolong tinggi dengan indeks keanekaragaman (E’) berkisar antara tidak stabil hingga stabil dan tidak terjadi dominansi spesies (C’).

Abstract

Streptococcus agalactiae are often the cause of Streptococcosis disease which attacks tilapia and results in mass death. Disease management needs to be done to control S. agalactiae infection using herbal ingredients and as an alternative to existing methods. The study consisted of two treatments (control and chitosan) of three repeats each. The treatment was tested in vivo by injection and challenged with S. agalactiae. Parameters observed include changes in morphology, fish behavior, and survival rates. The results of chitosan treatment on the parameters of changes in fish morphology and behavior showed milder infection than control, and a survival rate of 53.33%.

Abstract

Pasuruan sea waters are one of the strategic waters in East Java Province. Ecologically, Pasuruan Waters is a habitat for various types of aquatic organisms including phytoplankton. The Pasuruan sea area is the estuary of the rivers in Pasuruan which carry household, factory and other waste. This is feared to result in a decrease in water quality which can interfere with the growth of phytoplankton in the waters. Phytoplankton is a biological parameter that can be used as a bioindicator to evaluate the quality and fertility of a waters. The purpose of this study was to determine the composition and abundance of phytoplankton in Pasuruan Waters, East Java. This study used a descriptive explorative method with data collection using a purposive sampling method. The results showed that 22 genera were found from 5 divisions, namely the Chlorophyta division (6 genera), the Baccilariophyta division (11 genera), the Miozoa division (1 genera), the Cyanobacteria division (3 genera), and the Dinoflagellate division (1 genera). The abundance of phytoplankton ranges from 961 – 1815 cells/liter. The diversity index is in the low category with a range between 0 – 0.153. The dominance index of 0.6 - 0.8 indicates dominance in the waters and shows that the community structure is unstable. The dominant type of phytoplankton is Bacillariophyta.  Keywords:  Composition, abundance, phytoplankton, Pasuruan waters

Abstract

The high cost of feed makes farmers more creative and innovative in making fish feed as an alternative feed, especially for sangkuriang catfish (Clarias gariepinus var.). Alternative natural feed can be given to reduce costs incurred during maintenance such as the results of decomposition by palm loose fruits. The purpose of this study was to determine the effect of alternative natural feeding with the palm loose fruits decay method on the growth of length and body weight of sangkuriang catfish (Clarias gariepinus var.). Palm loose fruits was taken from oil palm plantations in the Gunung Lagan area, Gunung Meriah District, Aceh Singkil Regency, Aceh Province. This type of research is a type of experimental research with the research data obtained analyzed using the one-way ANOVA test to see the differences between treatments (A) softened palm loose fruits, (B) palm loose fruits that have caterpillars on the decaying media and (C) control treatment, taken softened palm loose fruits for treatment (A) and (B) that have caterpillars, then given to catfish as much as 2 handfuls and spread evenly in the pond. For treatment (C) or control treatment, commercial feed type FF-999 is given as much as 2 handfuls. The results showed that the body weight of sangkuriang catfish in treatment A with 3 replications was 55.87 g, treatment B was 62.72 g and treatment C was 58.56 g. Meanwhile, the body length of sangkuriang catfish in treatment A with 3 replications was 12.49 cm, treatment B was 14.61 cm and treatment C was 13.55 cm. In treatment C, the average value is not much different from treatment A.

Abstract

This study aims to verify the presence and map the distribution of coral reefs in the waters of Pangempang Hamlet, Muara Badak District, Kutai Kartanegara Regency. The methods used include field surveys, remote sensing image interpretation, and GIS-based spatial analysis. Data collection was conducted at 13 locations with varying depths and distances from the shore. The research results show that four locations have been verified to contain coral reef ecosystems, with areas ranging from 0.41 to 6.26 hectares. The location with the largest coral reef area is Batu Lampe Besar (6.26 hectares), which has great potential for conservation and marine ecotourism. Acropora coral is the dominant coral species found, as it was identified at every surveyed location. Based on these findings, it is recommended to implement community-based conservation efforts, regular monitoring, and further research to ensure the sustainability of the coral reef ecosystem in the Pangempang area.

Abstract

Medan Belawan, especially Sicanang Village, is a coastal area suitable for ponds. To replace pond water, the existing water must be drained first, so it's important to assess the land's drainage capability when selecting pond locations. This study aims to predict drainage ability by measuring the drainage depth (D) in pond channels at five observation stations. Using field surveys and both primary and secondary data, the study compares the results with criteria for aquaculture ponds. The findings show that Stations I (D = 55 cm), II (D = 46 cm), IV (D = 51 cm), and V (D = 39 cm) fall under Class 2 (D 30-60 cm), indicating they can be used for ponds since they can drain water by gravity, though not completely dry. Station III (D = 26 cm), classified as Class 3 (D < 30 cm), is unsuitable for ponds due to poor drainage and is better used as conservation land.
