profil rumput laut caulerpa racemosa dan Gracilaria verrucosa sebagai edible food caulerpa racemosa and Gracilaria verrucosa profile as edible foods
SAINTEK PERIKANAN : Indonesian Journal of Fisheries Science and Technology, 2013Co-Authors: Widodo Farid Maruf, Eko Nurcahya Dewi, Eko Susanto, Ratna Ibrahim, Ulfah AmaliaAbstract:Masyarakat terutama di pesisir pantai Jepara banyak mengkonsumsi Caulerpa racemosa dan Gracillaria verrucosa sebagai sayuran, namun tidak banyak diketahui tentang profil komposisi kimia, serat dan makromineral. Tujuan penelitian ini adalah untuk mengetahui komposisi kimia, serat, dan makromineral pada Caulerpa racemosa dan Gracilaria verrucosa yang tumbuh di perairan Jepara. C. racemosa diambil dari perairan Jepara dan G. verrucosa diambil dari dua jenis tambak yaitu tambak bersubstrat lumpur (a) dan pasir (b). Hasil analisa menunjukkan bahwa karbohidrat merupakan nutrisi yang dominan, diikuti kadar abu G. verrucosa dan protein pada C. racemossa . Jumlah mineral C. racemosa berturut-turut Na > Ca > K. Sedangkan pada G. verrucosa a jumlah mineral berturut-turut K >Na >Ca dan G. verrucosa b jumlah mineral berturut-turut Na >K >Ca. L-Threonine dan L-Glysine merupakan jumlah asam amino terbesar dalam rumput laut sedangkan L-asparagine tidak terdeteksi pada semua jenis rumput laut. Dilihat dari kandungan nutrisi dan mineral, kedua jenis rumput laut tersebut dapat dijadikan alternatif sebagai bahan bahan pangan. Kata kunci : Caulerpa racemossa , g racilaria verrucosa , nutrisi, edible food Jepara community consume Caulerpa racemossa and Gracillaria verrucosa but there is no much information about their chemical composition, fiber, and macro-minerals. This research was aimed to knowing chemical composition, fiber and macro-mineral in C. racemossa and G. verrucosa which grow in Jepara water area. C. racemossa was taken from Jepara water and G. verrucosa was taken from mud substrat (a) dan sand substrat (b). Carbohidrate was the dominant compound in all seaweed, ash dominant compounds in G. verrucosa and protein dominant compound C. racemossa, repectivelly. Minerals content in C. racemosaare was Na > Ca > K, respectivelly. In addition, minerals content in G. verrucosa a are K >Na >Ca and G. verrucosa ( b) are Na >K >Ca, repectivelly. L-Threonine and L-Glysine were the dominant amino acids in all seaweeds, whereas L-asparagine was not detected in all seaweeds. According to nutrition and mineral content in all seaweeds, they are able to use as an alternative food ingredients. Key words : Caulerpa racemossa, Gracilaria verrucosa, nutrisi, edible food

The Effect of Gracilaria verrucosa Extract Feeding to the Blood Glucose Content of White Rats (Rattus norvegicus)
SAINTEK PERIKANAN : Indonesian Journal of Fisheries Science and Technology, 2012Co-Authors: S A Candra Tama, Eko Nurcahya Dewi, Ratna IbrahimAbstract:F ood fibre could retard the absorption of glucose into blood. Gracilaria verrucosa seaweed species contains high food fibre. The objective of the study was to investigate the effect of different doses of G. verrucosa extract fed on white rats (Rattus norvegicus) to the blood glucose after one and two hours feeding of extract. The results indicated that the different G. verrucosa extract doses fed on white rats caused highly significant difference in the blood glucose contents from the blood samples of the treatments after one hour and two hours feeding time. The blood glucose contents were highly significant lower compared to the control. The highest dose was 4.5 g/kg body weight could reduce 53.65% of blood glucose content. Keywords : Gracilaria verrucosa, white rats, blood glucose.

The Utilization of Gracilaria verrucosa as Fish Processing Wastewater Biofilter
E3S Web of Conferences, 2020Co-Authors: Dhia Rahma Sari, Ratih Ida AdhariniAbstract:Wastewater from the smoked-fish processing industry has been known to cause water pollution in Pengadulan Estuary, Jepara. This research aimed to assess the ability of Gracilaria verrucosa as biofilter for fish processing wastewater and investigate its growth rate. This study was conducted at the Center for Brackish Water Aquaculture (BBPBAP) Jepara from January to April 2019. This study used three different G. verucosa biomass in 60 L aquarium: 150 gram (A); 200 gram (B); and 250 gram (C) and control. The parameters observed in the study were seaweed biomass, nutrient uptake by seaweed, and water quality parameters: salinity, water temperature, pH, dissolved oxygen, TSS, BOD5 , ammonia (NH3 ), nitrate (NO3 ), and phosphate (PO4 ). The results showed that G. verrucosa decreased ammonia, phosphate, and nitrate by 67.6%, 96%, and 37.1%, respectively. The result of RGR value has increased on the 10th and 30th day whereas on the 20th day were declined. The highest RGR value obtained on the 10th day on Treatment 1, which is 2.1% per day. It can be inferred that G. verrucosa is capable of increasing the water quality and the nutrient uptake in fish processing wastewater. Therefore, G. verrucosa held potential as both ecologically and economically sustainable biofilter.

The Utilization of Gracilaria verrucosa as shrimp ponds wastewater biofilter
E3S Web of Conferences, 2020Co-Authors: Cindy Martiana Trianti, Ratih Ida AdhariniAbstract:Gracilaria verrucosa as biofilter can absorb and utilize inorganic nitrogen and phosphorus contained in pollutants for its growth. This research aims to know the ability of G. verrucosa as shrimp pond waste biofilter, to know the difference in the quality of shrimp pond wastewater before and after treatment, and to learn more about the absorption capacity of G. verrucosa capability against shrimp pond wastewater. The experiment was conducted on a laboratory scale using a Completely Randomized Design (CRD) consisting of four treatments with three replications using G. verrucosa of different weights which were 100 g, 150 g, 200 g, and controls. The parameters observed in the study were water quality parameters, seaweed biomass, and seaweed absorption. The results obtained were temperature 27.2–30.1°C, TSS 7–76 mg.L-1 , pH 7.42–8.83, salinity 16–18 ppt, DO 1.7–5.3 mg.L-1 , biomass 74–210.7 g, ammonia effectively decreased on 10th day by 90%, nitrate on 20th day was 22.2% and phosphate value on 30th day was 20.1%. G. verrucosa absorbed nitrogen (N) 0.08% and phosphorus (P) 0.35%. G. verrucosa is potential as a biofilter and can be used as a species candidate for IMTA system.
