Abstract

Fried fish balls (basreng) are a type of product modified through two processing processes, namely boiling and frying. Frying process can have an impact on health due to high oil absorption resulting in high fat content values. This can be overcome by providing low-fat ingredients, namely lindur fruit flour. Lindur fruit flour tends to have a high starch content, namely in the hydroxyl group. The presence of hydroxyl groups is able to bind the water content of the dough, thereby reducing water evaporation which can form product pores when frying. Binding water to the dough reduces excessive oil absorption in the product. This study was conducted to determine the effect of lindur flour (Bruguiera gymnorrhiza) on chemical characteristic and acceptability of patin (Pangasius sp.). The treatment used in this study was the addition of 0%, 5%, 10%, dan 15% lindur fruit flour in the fish basreng. The parameters in this study are proximate content test and organoleptic test. The results showed that the addition of lindur fruit flour (Bruguiera gymnorrhiza) made a significant difference in the resulting basreng products. Patin basreng was the addition of 5% lindur fruit flour (Bruguiera gymnorrhiza) is the best patin basreng by the nutrient content and dan is the most preferred treatment by the panelis. Patin basreng was the addition of 5% lindur fruit flour (Bruguiera gymnorrhiza) has nutritional component 44,91% water; 1,78% ash; 8,27% protein; 8,11% fat; and 36,92% carbohydrate.

Abstract

The annual need for Artemia in Indonesia reaches 40-60 tons, but up to now 100% of this need is still imported. Various efforts have been made to produce Artemia cysts, but the main obstacle in cultivating Artemia to produce cysts is the availability of natural food, namely phytoplankton which can survive in high salinity. The use of organic materials such as bran can be a solution for feeding and can increase the density of Artemia, but excessive use of bran suspension in Artemia cultivation ponds can trigger a decrease in the quality of the water for the growth of Artemia. This research was conducted to determine the optimal concentration of bran feed for the growth and development of Artemia salina without compromising the water quality of the cultivation. The Artemia feed used in this study was a bran suspension enriched with lemuru fish oil (12 ml/L bran suspension). The bran feed concentration treatments in this study were 5 treatments sequentially, namely P1 to P5 with feed concentrations of 11, 18, 26.34, and 41 mg/L. Artemia salina cultivation in this study was carried out at an initial density of 50 ind/L with a salinity of 30 pptl. The research results showed that cultivating Artemia salina using bran suspension feed with different concentrations had an effect on the growth and development of Artemia salina. The best growth and development of Artemia results from cultivation using bran suspension feed with a concentration of 41 mg/L.

Abstract

The cultivation of vaname shrimp produces waste with a high nutrient content. This waste can be used as fertilizer in microalgae culture like Sprulina platensis. However, the N / P ratio in shrimp culture waste is low, namely 5.5: 1, while the need for growth of blue-green algae ranges from 10:1 - 16:1. Therefore, it is necessary to regulate the N: P ratio in shrimp culture waste to match the needs of S. platensis. The purpose of this study was to determine the effect of different N / P ratios on shrimp culture waste fertilizer on the growth of S. plantesis. This study used a Completely Randomized Design (CRD) which was divided into 6 treatments with 3 replications, as P0: Walne fertilizer (N / P ratio 17: 1), P1: shrimp culture waste fertilizer enriched with urea (N / P ratio 5,5: 1), P2 with N/P ratio of 10.5: 1, P3 with N/P ratio of 15.5: 1, P4 with N/P ratio of 20.5: 1 and P5 with N/P ratio 25.5: 1. The parameters observed were density and growth rate of S. platensis and water quality namely: temperature, salinity, and pH. The data obtained were processed using Analysis of Variance (ANOVA) and continued with Duncan's multiple range test. The results of this study indicate that the application of shrimp culture waste fertilizer with different N/P ratios affect the population and growth rate of S. platensis. Shrimp culture waste fertilizer with a N: P ratio of 15.5: 1 (P3) is the best treatment for the growth of S. platensis because it produces the highest population and growth rate compared to the other treatments.

Abstract

Panceng water is a coastal area that has quite a lot of activities, and this can trigger an increase in waste pollution. This polluting waste can cause an increase in the bioaccumulation of heavy metals in waters. Therefore, this research aims to obtain information on environmental management monitoring activities, such as water quality conditions by determining the concentration of heavy metals Pb, Cu and Zn in the roots of the Avicennia marina mangrove, water and sediment in Panceng Waters, Gresik. The method used was observation, examination of the heavy metals Pb, Cu, and Zn using ICP-MS, and the data was analyzed using quantitative descriptive methods. The results of the analysis of the concentration of the heavy metal Pb in the roots of the mangrove averaged 0.3 mg/kg, Cu 1.205 mg/kg and Zn 0.14 mg/kg. The concentration of heavy metals Pb in sediment was 5.49 mg/kg, Cu 15.7 mg/kg, and Zn 30.6 mg/kg. Meanwhile, the concentration of heavy metals Pb, Cu and Zn in sea water was not detected (ND). Overall water and sediment are still below the threshold. However, the concentration of heavy metals in the roots of the A. marina mangrove is relatively high, above the quality standards of Minister of Environment Decree No. 22 of 2021. Calculation of the level of heavy metal pollution based on Enrichment Factor (EF), Geo-Accmulation Index (Igeo) and Contamination factor (CF) values shows that the heavy metals Pb, Cu and Zn indicate levels of pollution and contamination that are still low to moderate. The Bio Concentration Factor (BCF) of A. marina in Panceng Waters, Gresik is included in the excluder category (BCF<1). The results of this research indicate that the A. marina mangrove can be developed as a phytoremediation agent because it is able to absorb and transfer heavy metals from the environment to other body tissues.

Abstract

Moina macrocopa is a natural food that has the potential for freshwater fish seeds, because of its high nutritional value, easy to digest and has a fast, fast breeding, and has a size that is in accordance with the fish's mouth opening. Problems in the use of M. macrocopa as natural food are constrained by the availability of M. macrocopa both from nature and from cultivation. Population density in M. macrocopa cultivation varies due to different quality of food used. The needs of M. macrocopa as natural food can be met if the quality and quantity of feed used optimally support population growth. This study aims to determine the effect of lemuru fish oil concentration in bran suspension fermentation on fecundity and offspring production of M. macrocopa. This study used a completely randomized design (CRD) consisting of five treatments three replications, namely: control treatment (0 mg/L lemuru fish oil, 100 gram bran), P1 (4 mg/L lemuru fish oil, 100 gram bran), P2 (lemuru fish oil 5 mg/L, 100 gram bran ), P3 (lemuru fish oil 6 mg/L, 100 gram bran), P4 (7 mg/L lemuru fish oil, 100 grams), and P5 (8 mg/L lemuru fish oil, 100 gram bran ).The parameters observed were fecundity and child production per parent and water quality. Data analysis used the Analysis of Variance test followed by Duncan's multiple test. The results showed that the cultivation of M. macrocopa using different bran suspension feed with supplemented lemuru fish oil affected the fecundity and production of children per M. macrocopa parent. The concentration of lemuru fish oil of 6 mg/L in the feed resulted in a fecundity of 24,00±2,00 eggs/parent and child production is 20,33±1,52 ind/parent.

Abstract

Lead (Pb) from batik dyeing waste that is thrown into the environment can pollute the environment so it needs processing before being thrown into the environment. The aim of this research is to determine the effect of green mussel shells as an adsorbent with different concentrations on reducing Pb heavy metal contamination in batik dyeing waste and to determine the optimal concentration of green mussel shells to reduce Pb heavy metal contamination in batik dyeing waste. The research method used was experimental with 4 treatments with different concentrations of green mussel shell ash as an adsorbent (0, 10, 20, and 30%). The results of the research showed that a green mussel shell ash concentration of 30% was the best concentration because it was able to reduce Pb levels in batik dyeing waste by 68.52%. Characterization of green mussel shell ash includes average pore radius (10.674 nm), total pore volume (0.005 cc/g), and surface area (0.969 m2/g).

Abstract

Marine debris has emerged as a significant environmental issue of growing global concern, closely linked to pollution and its impact on the environment. Understanding the distribution of marine waste in coastal areas is crucial, especially considering that beaches are key sites for various human activities such as tourism, fishing, and shipping. To address this, a study was conducted to analyze the composition of marine debris on three beaches in Banyuwangi Regency, East Java. The study took place in July and August of 2023, focusing on Boom, Cacalan, and Cemara beaches. Marine debris was collected along the coastline in 5 x 5 m transects, spaced 20 m apart, to identify and quantify the types of waste. The findings revealed that Boom Beach had the highest percentage of rubbish (46%), followed by Cemara Beach (30%) and Cacalan Beach (24%). Additionally, the highest abundance of rubbish per area was found at Boom Beach (5.97 ± 16.64 item/m2), Cemara Beach (3,92 ± 11,36 item/m2), and Cacalan Beach (3,12 ± 5,27 item/m2). Boom Beach and Cemara Beach were primarily dominated by plastic waste, while at Cacalan Beach, plastic waste and broken glass were found in nearly equal proportions. The calculation of the Clean Coast Index (CCI) indicated that all three beaches were significantly polluted. As a result, there is a clear need for focused attention on waste management at tourist beaches to preserve the aesthetics and comfort of beach visitors.

Abstract

Shellfish are a fishery commodity in Indonesia with increasing production annually, including a projected 137 thousand tons in 2024. Among the various types of shellfish, blood cockle is one of the most popular among citizens. Only 11-16% of their body is consumable, while the majority of it consists of shells that end up as waste. This waste is generally processed into crafts or animal feed. Blood cockle shell waste contains nitrogen (N) and phosphorus (P), which are necessary for higher and lower plants. This study was conducted to explore the potential of blood cockle shell waste as a growth medium for the microalgae Nitzschia sp. Reduction of the N and P ratio in this study was carried out to increase cell density by limiting nutrients of Nitzschia sp. There were five treatments with four replications in this study: P1 as a positive control (f/2 medium; N/P 8:1), P2 (cockle shell fertilizer medium/CSF; N/P 1,3:1), P3 (CSF+NaNO3; N/P 0,1:1), P4 (CSF+NaNO3; N/P 0,121:1), and P5 (CSF+NaNO3; N/P ratio 0,144:1). The results showed a significant difference (p<0.05) in the population of Nitzschia sp. in P3 with the highest density of 862.500 cells/ml and average daily growth of 275.000 cells/day. Based on this, the lowest N/P ratio limitation showed the best growth in Nitzschia sp. The low ratio indicates the prevention of toxicity in the culture medium. N limitation in this study also showed optimization of N utilization in the metabolic process of Nitzschia sp. N limitation is a strategy to increase the accumulation of nutrients in some microalgae, including Nitzschia sp., as observed in this study.

Abstract

Seagrass bed has an important role for biota in waters. The existence of fish in seagrass is influenced by other ecosystems close to seagrass, such as mangroves and coral reefs. This study focuses on fish associated with seagrass in Bama Beach. The data include seagrass coverage and the number of fish for the Diversity, Uniformity, and Dominance. The study was carried out on March 15 to 20, 2018 using the Underwater Visual Census. Results show that seagrass cover was highest in seagrass stations near mangroves (62,66%), while at stations near coral reefs was 37,66. The composition of fish associated with seagrass near mangroves was 361 individuals, while near reefs was 1.454 individuals. The values of diversity, uniformity, and dominance of fish associated with seagrass near mangroves are 2,62; 0,88; and 0,09 respectively while those associated with coral reefs have values of 2,93; 0,85; and 0,06. Family Aulostomidae was dominant in the morning at the station near mangroves, and in the afternoon was dominated by Apogonidae. At the station near coral reefs, the Family Pomacentridae was dominant both in the morning and afternoon. The seagrass conditions in this study are in the healthy category with quite diverse fishes. The level of fish diversity in seagrass was influenced by habitats associated with seagrasses than seagrass cover levels. The condition of Bama Beach as a conservation area is quite good, but the activity of tourists around the coastline must be monitored to maintain the environment.
