The Scalloped Spiny lobster (Panulirus homarus, Linnaeus 1758) known as one of the commercially harvested Panilurid lobster. This species was distributed widely across continents. Indonesia, as one of the largest archipelagic systems in the world, was also distribution area of the Scalloped Spiny lobster. These facts have led to questions regarding...

The spiny lobster (Panulirus homarus) is a valuable fishery commodity in Indonesia, particularly in its juvenile life form. However, identifying the early life forms of the spiny lobster can be challenging, as it exhibits similar morphological features compared to the juveniles of other Panilurid lobsters. Molecular-based identification, specifical...

Indonesia has one of the largest archipelagic systems in the world, potentially affecting the complex population structures of aquatic organisms. The Scalloped Spiny Ocean ( Panulirus homarus , Linnaeus 1758) has been identified widely distributed worldwide. These facts have led to questions regarding spiny lobster harvest and culture management by...

Keberadaan potensi sumber daya ikan, udang dan fauna akuatik lainnya di pesisir Muara Gembong menjadi target utama penangkapan dengan lokasinya berada di 13 muara sungai yang masuk ke Teluk Jakarta. Akan tetapi, hal tersebut berdampak terhadap terjadinya tekanan penangkapan baik di perairan Teluk Jakarta maupun pesisir Muara Gembong yang terus meni...

Invasive species are becoming issues in freshwater ecosystems throughout the world including Indonesia. Sermo Reservoir is located in Yogyakarta, Centra Java, was indicated to have invasive species identified as Cichlidae family. The study aimed to assess fish communities structure and identified invasive fish in Sermo Reservoir. The research was c...

Sumberdaya udang tangkapan di perairan Muara Gembong mengalami penurunan, salah satu penyebabnya adalah rusaknya habitat mangrove yang berakibat habitat asuhan udang terganggu. Kawasan asuhan udang menjadi salah satu opsi konservasi yaitu sebagai sumber rekruitmen stok udang dan biota laut lainnya. Tujuan penelitian ini untuk menentukan kawasan asu...

Humphead wrasse (Cheilinus undulatus), also called napoleon fish or katepas” in Anambas Archipelago Regency, Indonesia, is a reef fish which commonly found in tropical seas. Napoleon fish exploitation is still getting higher especially in Indonesia. Nevertheless, this species had listed as a protected species by the Indonesian Government as well as...

Abstrak Kelapa sawit (Elaeis guineensis Jacq.) merupakan tanaman yang mengandung karotenoid tinggi pada mesokarp yang merupakan bagian dari buah. Cahaya dan suhu dalam proses fotosintesis memberi pengaruh bagi kestabilan dan ketidakstabilan karotenoid dan klorofil. Penelitian ini bertujuan untuk mengetahui aktivitas fotostabilitas dan termostabilit...

Giant tiger shrimp (Penaeus monodon) has become a prime commodity in Indonesia which was produced by aquaculture and capture fisheries activities. Aceh Province, in this case mostly represented by Aceh Timur District, was well-known as the center of wild-captured-adult giant tiger shrimp. Several previous investigations had proved for its high-qual...

Aquatic plants are important part of aquatic ecosystem that can be used as an phytoremidiation agent, trapping organic matter in eutrophic waters as well as cleaning and controlling heavy metal pollution, pesticides and oil. The aim of research to assess the ability of some aquatic plants to organic matter and phosphate reduction for improve water...

ABSTRACT An effort to enhance ornate spiny lobster (Panulirus ornatus Fabricius,1798) population in wild through restocking is needed. Information regarding the genetic variation of original lobster population need to be observed prior to the restocking activity. This information was essential to avoid less-genetical varried organism being introduc...

Two seaweed species – Kappaphycus alvarezii (Rhodophyta) and Padina australis (Phaeophyta) – have been commercially viable raw materials for the food industry. Despite their usefulness as sources of carrageenan and alginate, there is little information concerning their chlorophylls and carotenoids. Composition and quantification of the chlorophylls...

Floating Treatment Wetlands (FTWs) are considered the most applicable and cost effective instrument for aquatic pollutant removal. This aquaponic–based bioremediation has become a potential alternative solution since inorganic (physical and chemical) treatment is seen to be ineffective for large–scale polluted objects. Numerous investigations have...

The development of rapid and automatic pigment characterization method become an important issue due to the fact that there are only less than 1% of plant pigments in the earth have been explored. In this research, a mathematical model based on artificial intelligence approach was developed to simplify and accelerate pigment characterization proces...

Aim: To investigate the amino and fatty acid contents in the gonad of Diadema setosum; body weight, hemoglobin count, number of neuron cells, weight and volume of brain of Rattus norvegicus, and lab rats. Materials and Methods: The contents of fatty and amino acids in gonad of D. setosum were analyzed by gas chromatography and high-performance liqu...

Palm carotene has potential as an application for a natural food colorant with bioactivity as pro-vitamin A and an antioxidant. However, during processing and storage, the palm carotene encounters excessive treatments. In this study, the stability of palm carotenes was observed in organic solvent and a food emulsion system in order to learn its mol...

The red alga Kappaphycus alvarezii (Doty) Doty ex P.C. Silva has been introduced and mono cultivated in Indonesia as a seaweed commodity. This species is specifically grown in shallow and clear seawater, although there are several reports concerning the cultivation in deep seawater. It is interesting to know compositional changes of chlorophylls an...

High-performance liquid chromatography (HPLC) has been commonly used as method of separating and identifying photosynthetic pigments such as chlorophylls and carotenoids because of such advantages as speed, high resolution and sensitivity. In this technique, high separation relies largely on the type of column material. This study compared the effi...

The general objective of this study was to evaluate the stability of encapsulated pigment prepared from brown seaweed (Sargassum sp). A simple and rapid extraction procedure was employed to collect brown–algal photosynthetic pigments, followed by encapsulation using freeze drying with maltodextrin and Tween–80 as the encapsulating agents. The produ...

The objectives of the present study were to evaluate the chlorophyll content of green leafy vegetables found commercially and carry out a comparative investigation between in vivo and in vitro data. The chlorophyll of green leafy vegetable can be used as visible parameters of the quality of vegetables during storage, since it will be degraded gradu...

Purple photosynthetic light-harvesting (LH2) is attractive complex module for hybrid nanostructures. Bacteriochlorophyll a in LH2 absorb at 320-400 nm, 585 nm and at near-infrared region (B800, B850 bands), while carotenoids absorb at 400-550 nm. Prior for application, LH2 has to be extracted from its native membrane and placed in suitable matrix....

Environmental and health problem caused by artificial colorant encourages the increasing usage of natural colorant nowadays. Natural colorant refers to the colorant that is derivate from living organism or minerals. Extensive research topic has been done to exploit these colorant, but recent data shows that only 0.5% of the wide range of plant pigm...

High performance liquid chromatography (HPLC) equipped with photodiode array (PDA) detection from 190-800 nm spectral range has been a method in great demand in analytical chemistry of natural products that offers three-dimensional data set.
