“…Efficiency analysis using formulas quoted from (Kasim et al, 2021;Picaulima et al, 2023) The formula is as follows: The hand line operates in the waters of Kei Kecil TPK conservation area using a relatively small fleet of less than 2 GT. It uses simple driving power, namely rowing, ketinting with a power of fishing fleet is the fishing fleet that uses outboard motor driving power, and the smallest is the rowing boat.…”

“…Analysis of the business effectiveness of small-scale hand line fishing fleets Production effectiveness analysis was conducted to determine the highest output level produced in the production process of small-scale hand-line fishery fleets in each season in the current Kei Kecil TPK conservation area. Efficiency analysis using the formula quoted from(Kasim et al, 2021;Picaulima et al, 2023) The formula is as follows: effectiveness of hand line fishery production in each season (kg/IDR) Q = Total Hand Line Fisheries Production in Each Season (kg) TC = Total catch cost of hand line fishing effort in each season (IDR)RESULT AND DISCUSSIONProduction of small-scale handline fisheries every season in the Kei Kecil Island Park Conservation AreaHand-line fisheries production is the work of capital goods production factors, and capital is used efficiently in the hand-line fishery production process to obtain effective results. The hand line for small fishermen in Southeast Maluku Regency is known as "bottom fishing" because the target catch is demersal fish resources and reef fish with high economic value (Wiyono et al, 2022)…”

The economic benefits of hand line production activities carried out by small fishermen utilizing some inputs to produce high economic value output each season in the Kei Kecil small island park (TPK) conservation area differ according to the driving power. Production cost efficiency, effectiveness of production results, and business profits are very important for the sustainability and development of small-scale hand-line fisheries. This study aims to analyze the economics of small-scale hand line production based on the driving power in each season in the TPK Kei conservation area. The type of data needed is primary and secondary data, and the collection method used is triangulation. The analysis used includes analysis of business profits, production cost efficiency, and effectiveness of production results. The results of the analysis show that the production of hand line carried out in the TPK Kei Kecil conservation area in each season is more efficient and effective in the hand line fishing fleet that uses hand line rowing and the highest business profit is the hand line fishing fleet that uses ketinting driving power. The production of small-scale hand lines in the TPK Kei conservation area is small in each season efficiently, effectively, and profitably.

“…In Castro's CSA algorithm, a highprobability mutation has been adopted for antibodies with high afnity, and a global search is performed on the problem space to maintain the diversity of the population. However, adopting this method will cause the algorithm to oscillate in the later stage of convergence, making it difcult to converge [21]. Terefore, the convergence optimization of the algorithm makes the algorithm adaptive to the high probability mutation, that is, as the number of iterations increases, the β in the algorithm decreases, and the decreasing equation is as follows:…”

Aiming at the identification of coal and gas outburst risk, using the advantages of the clone selection algorithm (CSA), such as self-adaptation and robustness, and the characteristics of fast convergence of particle swarm optimization (PSO) algorithm, the complex decoding problem, and mutation process brought by CSA binary coding are used. It is difficult to control the problem. Using PSO optimization, the problem of abnormal detection and identification in coal and gas outburst monitoring is developed and studied, and a CSA coal and gas outburst risk anomaly detection and identification model based on PSO optimization variation is established. The model uses the coal and gas outburst index data as a collection of antigen-stimulated antibodies to achieve abnormal detection and identification of measured data. With the help of the measured data, the verification results show that the model can effectively detect and identify the risk of coal and gas outburst, and the identification results are consistent with the risk of coal and gas outburst in the field. It can be used as an effective risk identification model to guide coal mining work.

“…Numerous investigations have been conducted to find the best methods for providing superior seeds of this seaweed, including tissue culture seed technology and clonal selection (Kasim et al, 2021), mass selection based on phenotypes of growth advantage and disease resistance (Fadilah et al, 2016), and genetic identification based on molecular markers using the Cytochrome Oxidase Subunit I (COI) gene (Ratnawati et al, 2020). However, vegetative propagation of genetic sources of seaweed possessing high phenotype diversity has not been genetically confirmed, thus posing an obstacle in improving seed quality.…”

The seaweed Kappaphycus alvarezii is a leading aquaculture commodity possessing high economic value that has been used as a raw material for various natural products, food, and pharmaceutical industries. The main challenge regarding its production, escpecially in Tarakan is the supply of superior seeds. Therefore, this study aims to obtain phylogenetic information and the cultivation performance of the selected seeds by identifying genetic sources based on molecular markers. DNA sequencing analysis was carried out using the molecular marker cox2-3 spacer on a collection comprising 16 cultivars from all over the country (Indonesia). The four haplotypes representing K. alvarezii to be cultivated in the city were produced by phylogenetic clustering and further molecular analysis using cox2-3 intergenic spacer mitochondrial DNA marker. These include the Kupang varieties and Natuna, also referred to as Lampung seedlings, which is a tissue culture plantlet used for development at SEAMEO-BIOTROP Bogor and propagated by the Lampung Marine Aquaculture Center (BBPBL), Tarakan. These varieties were genetically distances (pairwise comparisons based on mean Kimura 2-parameter model) ranging from 0.00-0.23 unit. The cultivation was carried out for 30 days in the waters of Tanjung Batu (Tj. Batu) Mamburungan, Tarakan, North Kalimantan, for 30 days. The result showed that the Natuna* as Lampung cultivar has superior performance compared to local cultivars (Takalar as Mamburungan Tanjung Batu, Tarakan, and Kupang). Furthermore, the genetic analysis with cox2-3 spacer markers had the potential as an effective seed selection tool for tracing genetic information in the development of superior seedlings in aquaculture activities.
