The research will be conducted in a time frame and location from March to April 2024 in Bandung City. The analysis method used is SWOT analysis. The initial stage involves the analysis of internal factors (IFAS) and external factors (EFAS). Next, perform the calculation of the IFE EFE matrix and the formulation of marketing strategies using the grand strategy matrix. Based on the results of the analysis, both internal factors and external factors each have 5 factors. Strengths include Good quality ornamental fish, strategic location, affordable prices, a large selection of fish species, and comfortable and clean stores. Weaknesses include hampered marketing activities, promotion has not been maximized, fish dying from the disease, do not update on social media, and unsatisfactory service. Opportunities include the trend of ornamental fish, the number of ornamental fish suppliers being relatively large, supportive government policies, consumer confidence in products, and ornamental fish as a hobby or decoration. Threats include changes in consumer tastes, increasingly fierce business competition, price games from competitors, the entry of ornamental fish from abroad, and a lack of market information. The results of the grand strategy matrix analysis show that the position of the X-axis (0.48) and the Y-axis (0.42) is in quadrant I, so the right strategy that can be applied is an aggressive strategy (SO) which means utilizing strengths and opportunities. S-O strategies that can be applied include maintaining and improving the quality of ornamental fish, increasing the number of different types of ornamental fish, setting prices that can be reached by consumers, expanding ornamental fish business premises, and arranging and maintaining the cleanliness of business premises.\u0000Keywords: SWOT analysis; Freshwater ornamental fish; Marketing strategy.\u0000Abstrak\u0000Tujuan penelitian ini adalah untuk menganalisis strategi pemasaran yang tepat yang dapat diterapkan pada usaha ikan hias air tawar di Kota Bandung.

Paransa","doi":"10.35800/jip.v12i1.52205","DOIUrl":"https://doi.org/10.35800/jip.v12i1.52205","url":null,"abstract":"The objectives of this study are 1) to Identify the specimen of macrobenthos attached to the substrate provided in 2 locations. 2) to determine the type of substrate attached by the larvae at both sites.  3) to determine the density of Macrobenthos attached to the substrate provided at 2 sites. A plywood plate had 16 holes with a diameter of 1 cm each that had been randomly filled with organic substrates, namely coconut fibers, palm fibers, shells with 'bysus' threads, and non-organic substrates in the form of plastic ropes. Each substrate has four replicates.  The plywood plate with 3 replicates was placed in each station.  The plate was removed and taken to the laboratory after 1 month. The identification up to family, genus, and species as well as the density of each species were applied.  The results showed that not only the larvae of Septifer bilocularis attached to organic and non-organic substrates, but six species of larvae were also identified. The sizes of new settler macrobenthos from 2 mm to 1 cm attached on organic and non-organic substrates were identified. The density of new settlers species attached to substrates varied from 0.03 – 0.5 individuals/cm2.  The new settlers identified 7 species in Tiwoho and 3 species in Malalayang.   \u0000Keywords: Settlement, Substrate, Tiwoho Coast, Malalayang Coas. \u0000Abstrak\u0000Tujuan dari penelitian ini adalah 1) Mengidentifikasi jenis-jenis  makrobenthos yang menempel pada substrat yang disediakan di 2 lokasi. 2) Mengidentifikasi jenis substrat sebagai tempat penempelan larva macrobenthos di  kedua lokasi, dan 3) Menentukan kepadatan jenis Makrobenthos  pada substrat yang disediakan di 2 lokasi. Triplek (plate) memiliki 16 lubang dengan ukuran diameter masing-masing 1 cm yang telah diisi secara acak dengan substrat organik yaitu serabut kelapa, serabut ijuk, cangkang ber ‘byssus’, serta substrat non organik berupa tali plastik. Masing-masing substrat ini memiliki 4 ulangan.  Selanjutnya, plate, masing-masing dengan 3 ulangan ditempatkan di setiap intertidal, Towoho dan Malalayang.  Plate diangkat setelah 1 bulan, yang dibawah ke laboratorium untuk foto dan diidentifikasi baik di tingkat jenis, genus, ataupun family.  Hasil penelitian menunjukkan bahwa tidak hanya larva kerang Septifer bilocularis (Linnaeus, 1758), yang menempel pada substrat organik dan non organik, tetapi ditemukan larva macrobenthos lainnya, yaitu 2 jenis dari Cerithum egenum (Gould, 1849), dan Calcarina defranci d'Orbigny, 1826, 2 family/genus, yaitu: Canthocamptidae dan Portunidae, dan 2 klass, yaitu : Polychaeta dan Demospongae.  Teridentifikasi jenis larva makro benthos yang baru menempel pada substrat substrat organik dan non-organik dengan ukuran yang bervariasi, yaitu dari 2 mm – 1 cm. Kepadatan jenis macrobenthos yang baru menempel adalah dari 0.03 – 0.5 individu/cm2.  Ada 7 jenis teridentifkasi di lokasi Tiwoho, dan 3 jenis teridentifkasi di Malalayang\u0000Kata kunci: Penempelan, Substrat, Pesisir Tiwoho, Pesisir Malalayang\u0000 ","PeriodicalId":331202,"journal":{"name":"Jurnal Ilmiah PLATAX","volume":"51 33","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139594539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
