Abstract

seaweed contains bioactive compounds that can be used to support human health. One of the seaweeds that are widely found in Indonesia is seaweed / brown algae. An example of brown algae, one of which is Padina australis. Padina australis is a seaweed that contains many bioactive compounds, such as alkaloids, flavonoids, saponins, tannins, and antioxidants. However, Padina australis is not widely applied and used in processed food products. So in seaweed research, Padina australis is used as seaweed tea. In this study, Padina australis seaweed tea was carried out the difference in length of immersion with hot water and the treatment of immersion time is 0 minutes, 5 minutes, 10 minutes, and 15 minutes. The bioactive compounds studied are alkaloids, flavonoids, saponins, tannins, and antioxidant activity. The results showed that the difference in immersion time there are bioactive components in the form of phytomias contained in Padina australis tea, among others: alkaloids, flavonoids, tannins, and saponins in each treatment (0 minutes, 5 minutes, 10 minutes, and 15 minutes). In the test the highest antioxidant activity on P4 treatment (15 minutes) was 47.7% and for the lowest on treatment P2 (5 minutes) by 44.8%.

Abstract

Biofloc technology is one of the alternative to overcome the problem of water quality of cultivation environment which was adapted from conventional waste management techniques. The purpose of this study was to assess the young catfish culture by applying bioflocs of some consortium products, such as Bacillus megaterium (BM), Supernit (SP), Depok 165 (DP165), Kayajaga (KJ) compared to non biofloc application for improving the water quality. The results of this study and statistical test showed that the lowest concentration of TAN by probiotic KJ was about 2.56 mg L-1, while the control was about 5.47 mg L-1, and the consortium of bacteria gave effect to  TAN value (p<0.05). The Lowest concentration of amonia by probiotic KJ was about 0.0001853 mg L-1, while control was about 0.0003973 mg L-1, and the consortium of bacteria did not give effect to amonia value (p>0.05). The lowest concentration of nitrite by probiotic BM was about 0.065 mg L-1, while the control  was about 0.124 mg L-1, and the consortium of bacteria gave effect to the nitrite value (p<0.05). The lowest concentration of nitrate by probiotic BM was about 1.203 mg L-1, while the control was about 3.437 mg L-1, and the consortium of bacteria gave effect to the nitrate value (p<0.05). Consortium of bacteria gave effect to the COD value (p<0.05), but all bioflocs treatments had an average value of COD higher than the control. The conclusion that the bioflocs aplication was able to improve the water quality shown by decreasing parameter values of TAN concentrations, ammonia, nitrite, and nitrate.

Abstract

The development of microalgae culture Spirulina platensis is interesting until now, this was caused S. platensis has multi-function in several sector. High price of commercial media for the culture needs prompting to search alternative medium which is not expensive, such as sprouts extract (ET) and Urea. The Data of research from the experiment on commercial media and alternative using Standard Error of the Mean (SEM) are : The threatment K (Kontrol) with commercial media “walne”, the growth of S. Platensis cell is 22105 cell/ml and protein levels is 22.17%. Treatment P4 with alternative media (6% ET+120 ppm urea) showed that result of growth of S. Platensis cell is not too different to the threatment K, the result is 21136 cell/mL and protein level is 18.55%. Both experiment showed that the difference of growth cell between both experiment is not significant. Another result of treatment which used alternative media are: Treatment P2 (6% ET+100 ppm) growth cell is 16.383 cell/mL, protein level is 17.07%; Treatment P1 (4% ET+ 100ppm) growth cell is 10.7669 cell/mL, protein level 10.10%. The lowest of growth cell is treatment P3 (4% MT+120 ppm), growth cell is 10.769 cell/mL and protein level 13.81%. The conclusion is combination of ET and urea able to replace medium of microalga culture, it is like commercial medium "walne" as the culture medium for the growth of S. platensis.

Abstract

Ikan lemuru (Sardinella longiceps) merupakan primadona bagi daerah Banyuwangi khususnya di Kecamatan Muncar. Potensi ikan lemuru yang cukup banyak dimanfaatkan menjadi olahan produk makanan bagi perusahaan yang berdiri di sekitaran Kecamatan Muncar. Mengingat kandungan protein yang cukup tinggi didalam limbah ikan lemuru yang berasal dari buangan limbah perusahaan, maka penelitian ini bertujuan untuk memanfaatkan limbah lemuru sebagai bahan baku nata de fish sebagai upaya meminimalisir dampak pencemaran. Sebanyak 4 perlakuan dilakukan dalam menentukan formulasi nata de fish, P2.C merupakan perlakuan terbaik karena menghasilkan nata de fish hingga 980 gr, dengan hasil kandungan proksimat (karbohidrat, protein, lemak, serat, nitrogen, mineral) yang lebih baik dibandingkan nata de coco. Selain meminimalisasi dampak pencemaran, nata de fish merupakan kreativitas olahan produk perikanan di Banyuwangi.

Abstract

Muncar subdistrict is an area famous for the potential of fisheries in Banyuwangi Regency. There are 11 villages in Muncar sub-district with the average livelihood of the community is as a fisherman. One of the factors of coastal areas is women, coastal women play an important role in households that rely on marine resources. In domestic economic activity, coastal women contribute and even dominate. Over time from year to year, there is a continuous exploitation of fish or marine resources in Muncar that causes difficulty in obtaining fish. Moreover, the conditions of extreme season change (catching and paceklik) make the acquisition of fishing businesses and household income of traditional fishermen decrease so that it requires income outside the capture business. It becomes the basis that the existence of women or fishermen's wives as a support for household income income is needed, but to support the potential of fishermen women in economic improvement, it is necessary to formulate a strategy of empowering women through the concept of eco-coefficient. The principle of coefficient is the production of precisely or efficiently so that it is economically and environmentally beneficial.

Abstract

Bomo Beach or commonly called Ria Bomo Beach is one of the beach destinations that has begun to be famous in Banyuwangi Regency since the last three years. One of the marine life commodities caught by fish that is still often found is lemuru fish. Lemuru that is caught is usually sold to the market or sold to local residents at a low price, but if it still does not sell well, the local community reprocesses it into several processed lemuru, one of which is commonly found is pindang lemuru. The decoction of lemuru from household industrial food (PIRT) in making lemuru pindang is usually thrown in the sewer that empties into the sea, thus impacting water pollution. Lemuru decoction actually still contains protein, fat, and omega 3, it can still be reused into processed fish products to increase the added value of a commodity, namely nata de fish. Program Kemitraan Masyarakat Programe (PKM) activities are carried out with the aim of increasing the level of fishermen's income by making nata de fish products based on product diversification "zero waste and healthy food" whose main source of ingredients used is lemuru stew (waste from making lemuru pindang). The first step taken by the team was preliminary research aimed at obtaining the right formulation in making nata de fish. The formulation became the standard for making nata de fish to become the latest superior product based on "zero waste and healthy food" for the people of Bomo Banyuwangi. During the focus group discusion, training and socialization of nata de fish making, product packaging, and socialization of PIRT permit certificate registration were carried out. To support the bomo community in the process of making nata de fish, the team provided a fermentation incubation that functions to minimize pathogenic bacteria so that contamination does not occur during the fermentation process. The final result in socialization and training activities, the Bomo community succeeded in making nata de fish with raw materials for lemuru stew waste.
