Abstract

Papaya (Carica papaya L.) is one of the agricultural commodities that is widely cultivated by farmers in almost all parts of Indonesia. This plant is widely cultivated because varied consumption of papaya by the community makes the demand for fresh papaya fruit in the market always increase. Therefore, the cultivation of this plant is very important to be applied properly. Cocopeat is a powder which is a waste of coconut coir processing. Our previous research has shown that cocopeat is an organic material that has a positive role in the growth of patchouli seedlings. This study aimed to examine how the effect of the addition of cocopeat on the quality and quantity of growth of papaya seedlings (Carica papaya L.var.calina) on experimental land within the Universitas Negeri Manado (Unima) campus in Tondano. Experimental research was carried out with one factor, the concentration of cocopeat, with 5 levels 10, 20, 30, 40 and 50%. The control used was an organic media compounded by the analysis without using cocopeat. Each treatment and control was repeated 30 times so that the number of experimental units was 180 experimental units. Randomization was carried out by placing 10 rows and 18 columns at the Unima Patchouli Nursery Installation. The quantity parameter is the number of days the seeds germinated and the number of seeds that were successfully germinated in each treatment and control. Quality parameters include seedling height at the age of 2 months after germination (first germination); number of leaves, leaf size, wet weight and dry weight at 2 months of age. Based on the results, it can be concluded that the use of organic media with the addition of cocopeat at a concentration of 10-50% had a significant effect on leaf number, leaf size, plant height, stem diameter, wet weight, and dry weight of papaya plants in the early growth period. The addition of cocopeat concentration in the growing media will have an increasing effect on the observed parameters. Especially for the parameter of the number of days of germination after planting did not show a significant difference between all treatments.

Abstract

Food allergy is a hypersensitive reaction of the body to certain substances that should not be harmful. One of the basic ingredients of foods that are reported to contain allergens is wheat. The type of allergen in wheat is found in gluten, which produces the protein gliadin. The protein gliadin is thought to be the cause of allergic reactions, especially in children and people who have celiac disease. Local food ingredients such as cassava can be used as alternative raw materials for gluten-free food products. The genetic diversity test of cassava is needed to determine the genetic variation of the cassava population and the ability to adapt to natural surroundings. Study of genetic diversity of a plant population can be analyzed by DNA fingerprinting technique using microsatellite molecular markers in the PCR method. Primer selection is a crucial stage because the position of the primer attachment will determine the success of the amplification process. Primer design and in silico PCR assay were carried out as a preliminary study to design the right primer to attach to a specific template. The method used digitally with the help of the NCBI Pick Primer page and FastPCR software for PCR stimulation, knowing the position of the primer attachment, precisely determining the primer and the length of the resulting amplicon. The results obtained in the form of 5 pairs of primer sequences attached to the microsatellite polymorphic locus. The length of the amplicon produced in each primer was 167 bp, 195 bp, 155 bp, 161 bp and 112 bp. The basis of primer selection consists of the length of the primary base, the TM value (melting temperature), the percentage of GC amount and the possibility of the formation of dimers between primers.

Abstract

Benoa Port has fishing vessel activities that are the foundation of Bali's tuna swamp fisheries (longlines). Sustainable tuna capture fisheries will be impossible to attain if the number of infractions in the marine and fisheries sectors continues to rise. The government's efforts to reduce infractions in marine and fisheries are achieved through tightening the oversight system. The Vessel Monitoring System (VMS) surveillance system was created to reduce breaches in the marine and fishery sectors. The goal of this study is to determine the monitoring and suspected indication of violations of longlines using the VMS at the Benoa PSDKP as well as to learn about the capture fisheries management strategy using VMS data on longlines at Benoa Port using an analytic hierarchy process (AHP) approach. This study used a qualitative-quantitative descriptive technique with AHP analysis to determine the value of the management priority scale. Based on the findings of monitoring longlines with web tracks from January to December 2022, the most targeted fishing area was the Indian Ocean High Seas, and the most prominent suspected indication of violation was the inactivity of VMS when the vessel was operating. The main approach for managing capture fisheries utilizing VMS data on longlines in Benoa Port with the AHP analysis is for the government to offer subsidies for installing VMS on all fishing vessels, particularly those under 30 GT.

Abstract

Budikdamber (fish farming in buckets) is an innovation from the aquaponics system that is carried out to keep catfish (C. gariepinus) and plants in the same container. In the Budikdamber system, it is important to pay attention to the high and low density of fish stocking because the rearing container used is a bucket. The purpose of this research was to determine the growth rate and survival rate of catfish at different stocking densities. This research was conducted with 3 treatments and each treatment had 3 repetitions, treatment A (40 fish/m3), treatment B (80 fish/m3), and treatment C (120 fish/m3). The observations showed that the highest specific growth rate of catfish was found in treatment A with a value of 12.74%, followed by treatment B 12.55% and treatment C 12.20%. The highest survival rate of catfish was found in treatment A, which was 90.8%, followed by treatment B at 87.9%, and treatment C at 86.7%. The highest feed conversion ratio (FCR) of catfish was found in treatment B, which was 0.475, followed by treatment A at 0.445, and the lowest FCR value was found in treatment C, which was 0.368. Water quality parameters measured during observations included dissolved oxygen (DO), temperature, acidity (pH), nitrite and nitrate, where all water quality parameters were still considered optimal for growth and survival of catfish.

Abstract

Water is a natural resource requirement needed for every living thing. Water pollution will affect water availability, so efforts are needed to fix it. The purpose of this study is to determine the quality of the water, analyze the degradation that occurs and provide recommendations for efforts that can be made to improve the ecosystem of Lake Tujuh Muara. The research location was Tujuh Muara Lake, Pamulang District, South Tangerang. The method used in this research is by using storet. Water quality data were collected at two monitoring points: the inlet and outlet areas. Observation of environmental degradation is carried out using field observations. Parameters observed in this study were biological dissolved oxygen (BOD), chemical oxygen demand (COD), detergent and coliform group. The analysis results show Tujuh Muara Lake's water quality exceeds the class II quality standard based on Government Regulation 22 of 2021. Two parameters exceed the quality standards: BOD and COD at the inlet point of 5.60 mg/L and 27.29 mg /l. The resulting BOD and COD values at the outlet point were 16.80 mg/L and 53.50 mg/L. Degradation of the aquatic environment is known by the abundance of water hyacinth plants that thrive and the turbidity and silting of the bottom of the lake waters. Efforts that can be made to improve the lake environment are by constructing constructed wetlands, building WWTPs, and implementing sustainable ecotourism

Abstract

The Benoa Bay area and its surroundings are a center of biodiversity at the ecosystem level in the southern coastal region of Bali. This area exhibits diverse ecosystems, including mangrove ecosystems, coral reefs, seagrass beds, and tidal flats. This research aims to analyze and describe the feeding ecology of Ambassis macracanthus in the waters of Benoa Bay. The study was conducted in May, at the end of the transitional season, and in July and August, during the eastern monsoon season in Benoa Bay Waters. Modified gill nets with mesh sizes of 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0 cm were used for capturing the fish. The fish were caught at three stations, which represented the characteristic conditions of the Benoa Bay Waters. Out of the 396 individuals caught during the study, only 100 were selected for examination. The average relative fullness gut index (RGI) of Ambassis macracanthus ranged from 0.39 to 0.67. The total Important Relative Index (IRI) value for the food of Ambassis macracanthus in Benoa Bay Waters was 951.27. Ambassis macracanthus in Benoa Bay Waters is an omnivorous species with a tendency towards herbivory, and 21 different organisms were found in its diet, including three classes of phytoplankton and three classes of zooplankton. The feeding strategy developed by Ambassis macracanthus in Benoa Bay Waters is generalist. This information about the fish can be used as a fundamental basis for managing fish in the waters of Benoa Bay.

Abstract

One of the shrimp commodities in high demand on the global market is the vannamei shrimp (Litopenaeus vannamei), and Indonesia is one of the leading countries in shrimp production. To improve the growth and quality of vannamei shrimp production, farming techniques continue to be developed. The practice of eye-stalk cutting on shrimp, also known as eyestalk-cutting, has become a technique actively employed in shrimp farming. However, it is considered a violation of animal welfare regulations. Anti-dopamine is another alternative that can inhibit the gonad maturation inhibiting hormone and improve shrimp reproductive performance. This study aims to determine the effect of eye stalk and anti-dopamine injection on the comparison of egg and nauplii production as well as the hatching rate carried out at Balai Produksi Induk Udang Unggul dan Kekerangan (BPIU2K) in Karangasem, Bali. The research method employed was experimental, with data analysis conducted using an independent t-test. The results showed that eye-stalk produces ±269,000 eggs with a hatching rate (HR) of 26.13%, while anti-dopamine can produce up to ±91,600 eggs with an HR of 83.31%. Total nauplii production from eye-stalk treatment reached ±75,000, and anti-dopamine nauplii production reached ±77,100. T-test results with a 95% significance level indicate a difference in the number of eggs but no significant difference in total nauplii production
