Abstract

The seaweed Caulerpa racemosa cultivation unit used in this study was the off-bottom method measuring 5 m x 10 m. This size can contain 5 stretch ropes/risers with a length of 10 m and a distance of 1 m between the stretch ropes/risers. Each stretch / riser line contains about 45 seed clump points with a distance between clumps of 15 cm. The observation procedure for the growth of Caulerpa racemosa seaweed was carried out by weighing the seaweed seeds in each stretch/riser rope. The weight of seed that is weighed is the weight of seeds at the time of planting and the weight of seaweed at harvest.The results showed that the average growth rate of seaweed Caulerpa racemosa was varied for each rope. In ris 1 rope, the average absolute weight growth reached 100.88 grams, ropes 113.33 grams, ris rope 3, 88.00 grams, rope ris 4, 116.00 grams, and rope ris 5, amounting to 113, 33 grams. In general, the highest growth in absolute weight was found in the fourth rope, which was 116.00 grams.

Abstract

One of the model fish used in climate change research is clown fish (A. ocellaris). The purpose of this research is to determine the effect of temperature increases on the growth and survival of clown fish. The experiment was carried out in a laboratory with a completely randomized design. The treatments were 28°C, 29°C, 30°C, and 31°C to observe clown fish growth in length and weight, relative growth rate, increased life, and color change over an 8-week period. The treatment temperature resulted in the best growth in length, weight, specific growth rate, and survival. The treatment temperature of 29OC (P0.05) resulted in the best growth in length, weight, specific growth rate, and survival, with values of 1.81 0.09 cm, 1.06 0.15g, 0.78 0. 09%, and 100%, respectively. At 31°C, growth and life were 1.02 0.04cm, 0.18 0.16 g, 0.30 0.04%, and 66.67 5.44%, respectively. At 31 degrees Celsius, the color of Badut fish changed from red to green to blue (P, 0.05). Temperature can cause badut fish mortality and adversely affect their growth.

Abstract

Seaweed of Caulerpa racemosa  has bright prospects for cultivation. In North Maluku province in general, the cultivation of seaweed Caulerpa sp has never been developed, even though the waters of North Maluku have enormous potential, because this type of seaweed is scattered in various marine waters in North Maluku. One of the efforts that needs to be done is to carry out this type of seaweed cultivation in an optimal and sustainable manner.The seaweed Caulerpa racemosa cultivation unit used in this study was the off-bottom method measuring 5 m x 10 m. This size can contain 5 stretch ropes/risers with a length of 10 m and a distance of 1 m between the stretch ropes/risers. Each stretch / riser line contains about 45 seed clump points with a distance between clumps of 15 cm. The observation procedure for the growth of Caulerpa racemosa seaweed was carried out by weighing the seaweed seeds in each stretch/riser rope. The weight of seed that is weighed is the weight of seeds at the time of planting and the weight of seaweed at harvest.The results showed that the average growth rate of  seaweed Caulerpa racemosa was varied for each rope. In ris 1 rope, the average absolute weight growth reached 100.88 grams, ropes 113.33 grams, ris rope 3, 88.00 grams, rope ris 4, 116.00 grams, and rope ris 5, amounting to 113, 33 grams. In general, the highest growth in absolute weight was found in the fourth rope, which was 116.00 grams.

Abstract

Biotechnology is used to apply technology to the C/N ratio by stimulating the activities of heterotrophic microorganisms, which derive food from carbon and nitrogen substrates in a certain ratio. The goal of this research was to see how the optimal carbon-nitrogen ratio affected water quality and floc volume in white leg shrimp (Litopenaeus vannamei) farming. This study took place in the UPT Integrated Laboratory Unkhair in Ternate City in July and August 2021. A fully randomized design (CRD) with four treatments and three replications was used in this investigation. Different C/N ratios had an effect on ammonia, nitrite, nitrate, floc volume, and feed conversion ratio, according to the research. The water quality parameters are still suitable for white leg shrimp cultivation. In white leg shrimp culture, the addition of C-organic molasses (different C/N ratios) was able to reduce the concentrations of (NH3), (NO2), and (NO3), and also greatly increase the flock volume and streamline the feed conversion ratio.Keywords:C/N RatioVannameiWastewaterBiofloc

Abstract

Small-scale fisheries generally refer to fisheries activities carried out by individuals or small groups using simple equipment and relatively small production capacity compared to large commercial fisheries. It has many obstacles and challenges faced by the perpetrators, including the technology used tends to be very simple. The same problem is also faced by tilapia farmers in Maffa Village, East Gane District, South Halmahera Regency. This community service activity aimed to implement an effective water quality management system in community tilapia rearing ponds, especially small-scale ones in Maffa Village. The activity was carried out in August-September 2024. The stages of activity implementation start from the preparation stage by the implementation team, socialization of activities, counseling to target partners in the form of delivering material related to the topic of activities, implementing the technology of aquaculture pond water quality management systems, and evaluation. The result of this activity is the implementation of counseling activities on effective water quality management systems in aquaculture ponds. In addition, the application of technology in the form of an aeration system was also well implemented, where the target partners' aquaculture ponds currently use a blower equipped with a diffusser to supply dissolved oxygen in the pond. The evaluation of the activity showed that more than 80% of the target partners understood and had skills in the application of this technology, where 81.82% of the cultivator group members understood the material about the technology applied and 90.91% actively participated and had skills in the technology application activities carried out. In conclusion, this activity has been successfully carried out in the form of counseling and the availability of aeration systems in the target partners' tilapia farming ponds.

Abstract

The low environmental quality of pond water is caused, among other things, by the large amount of organic waste and nutrients (feed components) in pond water outflow. The remaining feed and feces (feces) decompose in pond water before being dumped into the nearby rivers, resulting in the discharge of high levels of nutrients and organic waste. One method for enhancing the effluent quality from aquaculture is a biofilter. In order to reduce and absorb dissolved organic contaminants, biofilters are used. It is possible to employ Gracilaria sp. as a biofilter, which is an efficient technique to increase sanitation. The study' goals were to determine how well Gracilaria sp. developed and how well seaweed absorbed N and P elements from vaname shrimp culture waste, specifically ammonia (NH3), nitrite (NO2), and nitrate (NO3). Three different treatments for the weights of the seaweed were employed in the study: 50, 75, and 100 grams. The analysis showed that the 100 g of Gracilaria sp. was very effective in absorbing N and P waste. It was discovered that N and P component absorption was, respectively, 75.10% and 75.15% effective.
