This research aims to formulate a business sustainability strategy based on its dimensions. Strategy formulation is carried out through Strengths, Weaknesses, Opportunities, Threats (SWOT) analysis, preceded by sustainability analysis by modification of the Rapid Appraisal for Fisheries (RAPFISH mod) with 5 dimensions and 20 attributes for each dimension. Respondents totaled 33 people from business actors, researchers and academics, Tual City Fisheries Service staff and fisheries extension servicers who were selected using purposive sampling. Based on the sustainability index values, it was found that the sustainability status is still not good, 4 dimensions (57.17 for environmental; 52.89 for economic; 54.29 for social; 55.13 for technology) are in the sufficient/enough category, and 1 dimension (44.89 for institutional) and 49.95 multidimensionally falls into the poor category. All dimensional attributes, based on the criteria, become SWOT factors which are analyzed further by Internal and External Factor Analysis Summary (IFAS and EFAS). As a result, business activities are in Quadrant II, so the grand strategy is diversification, which in this case is defined as changing or expanding efforts. Strategy formulation is then carrie
ABSTRACTThe tuna (Euthynnus affinis) smoking business in South Dullah Island, Tual City is not yet sustainable.本研究旨在根据其各方面因素制定企业可持续发展战略。战略制定是通过优势、劣势、机会、威胁（SWOT）分析进行的，然后使用渔业快速评估模型（RAPFISH mod）进行可持续发展分析，该模型有 5 个维度，每个维度有 20 个属性。通过有目的的抽样，从企业参与者、研究人员和学者、图勒市渔业局工作人员和渔业推广人员中选出了 33 名受访者。根据可持续发展指数值，发现可持续发展状况仍然不佳，4 个维度（环境 57.17；经济 52.89；社会 54.29；技术 55.13）处于中等水平，1 个维度（制度 44.89）和 49.95 个多维度处于较差水平。根据标准，所有维度属性都成为 SWOT 因素，并使用内部因素分析概要和外部因素分析概要（IFAS 和 EFAS）对其进行进一步分析。结果，企业活动处于第二象限，因此战略是多元化，在这种情况下，多元化被解释为改变或扩大努力。然后通过 SWOT 矩阵进行战略制定，结果是在许可、储存设施、熏制设施和营销方面做出改变或扩大努力：熏鱼、金枪鱼、RAPFISH、商业可持续发展战略、SWOTABSTRACTT图尔市南部杜拉岛的熏鲭金枪鱼（Euthynnus affinis）业务尚未实现可持续发展。本研究旨在根据业务的各个层面制定业务可持续发展战略。战略制定是通过优势、劣势、机会、威胁（SWOT）分析进行的，在此之前，通过修改渔业快速评估（RAPFISH 模式）的 5 个维度和每个维度的 20 个属性进行可持续发展分析。受访者共 33 人，分别来自企业参与者、研究人员和学者、图勒市渔业局工作人员和渔业推广服务人员，他们都是通过有目的抽样选出的。根据可持续发展指数值，发现可持续发展状况仍然不佳，4 个维度（环境 57.17；经济 52.89；社会 54.29；技术 55.13）属于足够/足够类别，1 个维度（机构 44.89）和 49.95 的多维度属于较差类别。根据标准，所有维度属性都成为 SWOT 因素，并通过内部和外部因素分析摘要（IFAS 和 EFAS）进行进一步分析。因此，企业活动处于第二象限，所以大战略是多元化，在这种情况下，多元化被定义为改变或扩大努力。然后通过 SWOT 矩阵制定战略。结果是改变或扩大在许可、储存设施、吸烟设施和营销方面的努力。关键词企业可持续发展战略、RAPFISH、SWOT、烟熏鲭金枪鱼

ABSTRAKIkan kurisi merupakan hasil tangkapan yang cukup melimpah di Pelabuhan Perikanan Labuhan Maringgai, Lampung Timur. Harga ikan kurisi relatif terjangkau bagi masyarakat lokal ataupun internasional. Beralihnya masyarakat dari konsumsi daging merah ke ikan menyebabkan tingginya permintaan akan ketersediaan ikan kurisi. Peningkatan penangkapan ikan kurisi di Labuhan Maringgai menyebabkan diperlukannya langkah lebih lanjut terkait informasi aspek biologi ikan sehingga terbentuk pengelolaan perikanan yang berkelanjutan. Penelitian ini bertujuan untuk mengetahui pola pertumbuhan dan faktor kondisi ikan kurisi (Nemipterus japonicus) di Labuhan Maringgai, Lampung Timur. Pengambilan data dilakukan pada Bulan November 2023 – Januari 2024 dengan tiga kali pengamatan. Sebaran frekuensi panjang total ikan kurisi di Labuhan Maringgai memiliki kisaran panjang dan berat masing-masing 115 – 230 mm dan 18 – 159 g. Ukuran panjang ikan terbanyak berada pada selang kelas 147 – 162 mm. Hasil analisis panjang berat menunjukkan pola pertumbuhan ikan kurisi memiliki sifat alometrik negatif dengan persamaan W = 0.004 L1.89. Fungsi fisiologis ikan kurisi di perairan Labuhan Maringgai berada pada kondisi yang baik berdasarkan nilai rata-rata faktor kondisi (Kn) sebesar 1.06. Hal ini menjelaskan bahwa ekosistem perairan sebagai habitat ikan berada dalam keadaan baik yang dimungkinkan karena cukupnya ketersediaan makanan dan faktor abiotik lainnya. Kata Kunci: faktor kondisi, ikan kurisi, Labuhan Maringgai, pola pertumbuhanABSTRACTJapanese threadfin bream (Nemipterus japonicus) is a fairly abundant catch at the Labuhan Maringgai Fishing Port, East Lampung. The species is relatively affordable for local and international community. Switching from red meat to fish consumption has led to a high demand for the availability of this species. The increase in threadfin bream fishing has required further steps related to information on biological aspects of species to ensure a sustainable fisheries management. This study aims to determine the growth patterns and condition factors of Japanese threadfin bream. Data were collected in November 2023 to January 2024 with three observations. The species frequency distribution has a length and weight range of 115 – 230 mm and 18 – 159 g, respectively. Most of the fish lengths were in 147 to 162 mm class interval. The results of length-weight analysis show the growth pattern of the species has a negative allometric (W = 0.004 L1.89). The physiological function of the species is in good condition based on the average condition factor (Kn) of 1.06. This explains the aquatic ecosystem as a fish habitat is in good condition, which is possible due to the sufficient availability of food and other abiotic factors.Key words: condition factor, growth pattern, Japanese threadfin bream, Labuhan Maringgai

The research aims to create a mangrove ecotourism development model based on social capital through its elements, which is located in Banyuurip Village, Ujung Pangkah District, Gresik and is known as the Banyuurip Mangrove Center (BMC), where ecotourism is a form of tourist trip to natural areas carried out for the purpose of to improve the welfare of local communities and maintain environmental preservation in the area. Qualitative method with an emic approach (emic view/perception of informants) and an etic approach (ethic view/researcher's interpretation based on concepts/theories and relevant study results. The emic approach tries to explain a phenomenon in society from the perspective of society itself (people's views). in), on the other hand, ethics is the use of a distant outsider's point of view to explain a phenomenon in society. Data collected using observation, interviews and document study methods are then analyzed using the Milles and Huberman model analysis. Based on the strategic relationship between social capital and development Mangrove eco-tourism, increasing community participation to develop eco-tourism is a model for developing mangrove eco-tourism.
本研究旨在通过社会资本要素创建基于社会资本的红树林生态旅游发展模式，该模式位于格罗西克州乌戎邦卡县班尤里普村，被称为班尤里普红树林中心（BMC），生态旅游是一种以改善当地社区福利和维护该地区环境保护为目的的自然地区旅游形式。采用定性方法，包括情绪方法（情绪观点/信息提供者的看法）和伦理方法（伦理观点/研究者基于概念/理论和相关研究结果的解释）。情绪法（emic approach）试图从社会本身（人们的观点）的角度来解释社会现象，而伦理法（ethic approach）则是用遥远的局外人的观点来解释社会现象。使用观察法、访谈法和文献研究法收集到的数据将通过 Milles 和 Huberman 模型进行分析。基于社会资本与发展红树林生态旅游之间的战略关系，增加社区参与发展生态旅游是发展红树林生态旅游的一种模式。

water. Treatment D is the best dose among other treatments because carpain works to suppress the central nervous system. Karpain has the activity of suppressing the Central Nervous system by binding Na+ ions to the nerves. Na+ ions function to deliver nerve impulses until action occurs. The Argulus nerve is connected to the sucker which functions to attach. The compressed nerve cannot transmit nerve impulses to the sucker, resulting in Argulus being unable to infest the goldfish. Papaya seed juice with different concentrations has a very significant effect on Argulus parasites. Giving 60 ml/l (treatment D) can suppress Argulus which is very high, namely 30.56%, giving 40 ml/l (treatment C) can suppress Argulus, namely 25%. 20 ml/l (treatment B) can suppress Argulus, namely 11.11%. Giving 0 ml (treatment A) cannot suppress the growth of Argulus or the same as 0%.

ABSTRACTThe research aims to determine the structure of the plankton community in the waters of Gampong Peunaga Cut Ujong, Meureubo, Meulaboh, West Aceh. The study was conducted in September 2023. The collection point consisted of 3 stations, and sampling was carried out at high tide with three repetitions. The filtering process uses a plankton net with a mesh size of 30 µm. Phytoplankton at the research location consists of five classes, namely Cyanophyceae, Euglenophyceae, Chlorophyceae, Bacillariophyceae, and Dinophyceae. Meanwhile, zooplankton consists of 7 groups consisting of Protozoa, Rotifera, Crustacea, Polychaeta, Gastropoda, Pelecypoda, and Nematoda. Phytoplankton has the highest percentage in the Bacillariophyceae class, reaching 71.7%, and the lowest 1% (Dinophyceae, Euglenophyceae, and Chlorophyceae). The abundance of phytoplankton at station three during the study ranged between 2,025,600 cells/m3 - 6,710,400 cells/m3 and zooplankton in the range of 23,400 ind/m3 - 33,480 ind/m3. The average diversity index (H') for phytoplankton was 1.04, the uniformity index (E) was 0.40, and the dominance index (C) was 0.50. Meanwhile, zooplankton has values H' (1.42), E (0.65), and D (0.36). To maintain the Peunaga estuary area as an ideal buffer area, it is recommended to regularly monitor the community structure of aquatic biota (plankton, benthos, and fish).Keywords: buffer ecosystem, community structure, dominance index, Navicula sp.
ABSTRACTThe research aims to determine the structure of the plankton community in the waters of Gampong Peunaga Cut Ujong, Meureubo, Meulaboh, West Aceh.研究于 2023 年 9 月进行。采集点由 3 个站点组成，在涨潮时采样，重复三次。过滤过程使用网眼尺寸为 30 微米的浮游生物网。研究地点的浮游植物包括五类，即蓝藻纲、优藻纲、叶绿藻纲、纤毛虫纲和鼎叶藻纲。浮游动物则包括原生动物、轮虫、甲壳动物、多毛纲、腹足纲、卵足纲和线虫纲 7 个类群。浮游植物中，叶绿体类（Bacillariophyceae）所占比例最高，达到 71.7%，而叶绿体类（Dinophyceae、Euglenophyceae 和 Chlorophyceae）所占比例最低，仅为 1%。研究期间，三号站浮游植物的丰度介于 2,025,600 cells/m3 - 6,710,400 cells/m3 之间，浮游动物的丰度介于 23,400 ind/m3 - 33,480 ind/m3 之间。浮游植物的平均多样性指数（H'）为 1.04，均匀性指数（E）为 0.40，优势度指数（C）为 0.50。浮游动物的平均均匀指数（H'）为 1.04，均匀指数（E）为 0.40，优势指数（C）为 0.50。为保持 Peunaga 河口地区作为理想缓冲区的地位，建议定期监测水生生物群落结构（浮游生物、底栖生物和鱼类）。
