During the increasingly fierce competition in the Islamic finance industry, strategic steps are needed to increase public intention to save. This study aims to analyze the influence of shariah financial literacy, religiosity, attitudes, subjective norms, and behavior control on the intention to save at Indonesian Islamic Banks with the Theory of Planned Behavior (TPB) approach and formulate managerial implications for Indonesian Islamic Banks. This research was conducted on 200 respondents selected by voluntary sampling with Muslim criteria who had never had savings at Bank Syariah Indonesia and lived in the Greater Jakarta area. Data were collected online using a questionnaire and Structural Equation Modelling. The results showed that financial literacy has no significant effect on attitudes and behavior control; on the contrary, religiosity has a significant positive effect on attitudes and behavior control. Furthermore, subjective norms positively affect the intention to save but do not affect attitudes. On the other hand, attitude and behavior control significantly positively affect the intention to save. Based on the research results, Indonesian Islamic Banks can develop business by emphasizing the religiosity side to inspire people to prefer Islamic banks over conventional banks. Furthermore, Bank Syariah Indonesia should use social-environmental reference factors like friends and family.

Species list of economical fish landed in Muara Baru Modern Fish Market, Jakarta needs to be examined. Fish species information needs to know the species of fish being traded. However, many species are difficult to identify morphologically. The aim of this research was to identify fish based on their morphological characters and DNA barcoding. The methods of this research were morphologic, morphometric, and molecular identification with DNA barcoding using PCR. Morphological analysis results showed that fish samples have unique characteristics in the presence of spots on their bodies and fading in the abdomen. Morphometric observations were made with 19 different characters and weight measurements. The 19 fish characters observed have a standard deviation of <1, mean that the fish samples taken have a size that was not much different. A comparison ratio of 18 morphometric characters to total length (PT) showed variable results. Genetic analysis of the fish studied had the Max Score and Total Score was same, 1201, Query Coverage was 95%, and Ident was 100%. Based on morphological analysis and DNA barcoding used by fish species identified as Scatophagus argus species. Both methods were successfully carried out and the two methods complement each other to identify fish species correctly and accurately. Jumlah ikan ekonomis yang banyak diperjualbelikan di Pasar Muara Baru, Jakarta perlu dilakukan penelitian. Informasi spesies ikan perlu diketahui untuk mengetahui jenis ikan yang diperjualbelikan. Penelitian ini bertujuan untuk mengidentifikasi morfologi ikan dengan pendekatan studi morfometrik dan DNA barcoding. Metode yang digunakan dalam penelitian ini yaitu pengamatan morfologi dan pengukuran morfometri serta identifikasi molekuler dengan DNA barcoding menggunakan PCR. Hasil analisis morfologi menunjukkan bahwa sampel ikan memiliki karakteristik yang unik dengan adanya corak totol di seluruh tubuhnya dan memudar di bagian perut. Pengamatan morfometrik dilakukan dengan 19 karakter yang berbeda serta pengukuran berat. 19 karakter ikan yang diamati memiliki standar deviasi yang <1, artinya sampel ikan yang terambil memiliki ukuran yang tidak jauh berbeda. Rasio perbandingan 18 karakter morfometri terhadap panjang total (PT) menunjukkan hasil yang bervariasi. Analisis genetik dari ikan  yang diteliti memiliki Max Score dan Total Score sama yaitu 1201 dengan Query Coverage 95%, dan Ident 100%. Berdasarkan analisis morfologi dan DNA barcoding yang digunakan spesies ikan teridenfikasi spesies Scatophagus argus.  Kedua metode tersebut berhasil dilakukan dan kedua metode tersebut saling melengkapi untuk melakukan identifikasi spesies ikan secara tepat dan akurat.
