Abstract

Banjaran River is a river that is widely used by local people for their daily needs, including for bathing, drinking water, washing, and irrigation of agricultural land. These activities will cause changes in the quality of the waters of the Banjaran River so that it will cause water pollution, especially pollution from organic materials. This pollution will cause changes in the structure of the biota community, one of which is the phytoplankton in the Banjaran River. Phytoplankton are organisms that play a role in providing nutrients and maintaining the balance of aquatic ecosystems. The purpose of this study was to determine the structure of the phytoplankton community in the Banjaran River, Banyumas Regency. The method used in this research is purposive sampling, with 4 sampling points and 3 repetitions. Sampling was carried out in April-May 2021 with an interval of 2 weeks. Data analysis in this study includes the calculation of abundance, diversity index, and phytoplankton dominance index. The results showed that the abundance of phytoplankton in the Banjaran River was 453-720 individuals.L-1, the diversity index was 1.97-2.25, and the dominance index was 0.13-0.18. These results indicate that the structure of the phytoplankton community in the Banjaran River is in moderate diversity and there is no particular species that dominates in these rivers.Keywords: Phytoplankton, Banjaran River, Aquatic Ecosystem.

Abstract

Tigawaja fish (Nibea sp.) is a demersal fish that is commonly found in Indonesian waters. Tigawaja fish is a white-fleshed fish that contains about 18% protein, 0.03% total fat, vitamin A, niacin, calcium, and sodium. However, there are still few studies that discuss the growth characteristic of Tigawaja fish, hence, the management of Tigawaja fish resources cannot be optimized. Current study aims to determine the relationship between length and weight and condition factors of Tigawaja fish. Data collection was carried out at PPI Cikidang Pangandaran, West Java in February 2021. The field work method used random sampling of fish landed at PPI Cikidang Pangandaran. The parameters measured including the length and weight of the fish, and the data were analyzed descriptively. The results showed that the growth pattern of Tigawaja fish landed at PPI Cikidang Pangandaran was negative allometric with b value at 2.71. Regression analysis of the relationship between length and weight of Tigawaja fish resulted a coefficient of determination R2 of 85.69% indicating a very strong relationship between length and weight of Tigawaja fish. The results of the condition factor values have an average of 1.41 and relative weight with an average of 101.30. The results of the regression analysis of the relationship between condition factors and relative weight resulted a coefficient of determination R2 of 76.18% showed the relationship was very strong.Keywords: Tigawaja fish, length, weight, condition factor, relative weight, PPI Cikidang Pangandaran

Abstract

The waters of the Bangka Belitung islands are shallow waters that are affected by tides. The tides in these waters originate from the propagation of the Natuna and Java Seas, so they have unique characteristics. This study aims to analyze the amplitude and phase difference at 2 stations representing Bangka and Belitung Islands with the final output of LAT and HAT information as marine cadastral recommendations at Tanjung Pesona and Tanjung Tinggi stations and safe depths for ports in PPN Sungailiat and PPN Tanjung Pandan. . Tidal data for 1 year with time intervals of 1 hour in 2015 were used to extract the harmonic components to determine the type of tide and calculate the tidal level at each station. The results obtained are 19 harmonic components with a diurnal tide type. The water level at Tanjung Pesona is higher than the high Tanjung, which is described by tidal levels with HAT 2.64 and 1.72 m. Safe depth of harbor pond. In the LAT condition (lowest recess), the water level at Tanjung Pesona station is above the Sungailiat PPN pool's maximum depth; on the other hand, the Tanjung Pandan PPN LAT is 0.44 m below the maximum depth of the port pool.Key Word: Bangka Belitung, chart datum, LAT, HAT, tidal level

Abstract

Padelegan Beach is one of the beaches used for tourism and seaweed cultivation activities, which is located in Pademawu District, Pamekasan Regency. The distribution of water turbidity plays an important role in the success of seaweed cultivation activities and salt ponds along the Jumiang coast. The purpose of this research is to know the condition of turbidities distribution in Jumiang waters. The sampling method used the purposive sampling method with the location of nine sampling stations. The location of the turbidity measurement is based on thereare near the coast (points 1, 2, 3), beaches (points 4, 5, 6), and the high seas (7, 8, 9). Turbidity was measured using the Lutron TU-2016 Turbidity Meter. The results show that the turbidity distribution at station points near the coast is higher in value than at high sea station points. The highest turbidity value is 29,82 NTU in the coastal area, while the lowest is 4,35 NTU the offshore. The turbidity value in Jumiang coastal waters shows a value below the threshold for turbidity that is intended for cultivation activities.Keywords: characteristics, turbidity, The Padelegan Beach

Abstract

The high productivity and quality of the harvested prawn are the main objectives of the intensive giant freshwater prawn (GFP) culture. Therefore, the breeding program to create a superior strain of the prawn has been conducted in several countries to support prawn farming. The purpose of this study was to evaluate the productivity and female reproductive performance of the GFP superior strains, namely the selected GI Macro (GI) and Siratu (SR) in the three farming conditions. The GI has resulted from an individual selection program based on standard length and maturation level characters. The multi-location test was conducted in the grow-out phase for 90 days at the three locations based on altitude, namely low-lands (in Subang, 10-25 m above the sea level, asl), medium-lands (in Ciamis, 70-100 m asl), high-lands (in Kuningan, 700-800 m asl). The growth characters consisting of total length/TL, standard length/SL, and body weight/BB of GI and SR were not significantly different, both on the Low, medium, and high lands ponds.  The survival rate of the GI (87,3±7.26%) was significantly higher than the SR (71.0±0.08%) in the medium-land pond.  In the high-lands pond, the survival rate of the SR (72.33±0.32%) was significantly higher than the GI (55.8±6.27%). Meanwhile, the productivity and percentage of the gravid female in the low-lands pond were not significantly different. The data suggested that the selected GI Macro is a location-specific genotype, more suitable to be cultured in the low and moderate-lands pond with warm temperature characteristics. Keywords: freshwater prawn, growth, multi-location, reproduction

Abstract

The need for feed determines 60-70% of aquaculture total production cost. Hence, the feed factor plays a very important role in performing an effective, efficient, inclusive, and sustainable aquaculture. The requirements needed to be a good cultivar are fulfilment of macronutrients and micronutrients, toxin-free, and accessible. Maggot can be used as a natural feed alternative in cultivation activities due to its sufficient nutrients content. Since 2012, aquaculture activities in Indonesia have increased alongside the rising needs for food and population growth. In this research, we conducted a research on the cultivation process of maggot by constructing three effective, efficient, and organized prototypes to achieve natural feed alternative for fish. In the first prototype, the hatching container (70x80x50 cm) will be designed with IoT censor for environmental parameter that is accessible in real time via the Blynk IoT platform. The second prototype is the vertical biopond, in which the structure and plastic container will be used to grow maggot. The structure of vertical biopond will be that of two-rack wood shelf with size specification of 80x100x34 cm. An important note to take, all designs will be created vertically. The third prototype is a 3 in 1 stall that has three components which are green net (200x150x100 cm), pupation container (30x42x15 cm), and hatching container (20x23x10 cm). All three designs can optimize the provision of economical and ecological feed that supports the fulfilment of Sustainable Development Goals in Indonesia.Keywords: Aquaculture, Black soldier fly, Internet, Natural feed, and SDGs
