Abstract

ABSTRAKPenelitian ini berfokus pada perancangan E-Magazine interaktif sebagai media promosi digital bagi Smiling Coral Indonesia (SCI), sebuah kelompok konservasi berbasis di Pulau Pramuka, Kepulauan Seribu. SCI selama ini mengandalkan media sosial dan brosur digital, namun konten yang disajikan masih bersifat umum, terbatas, dan belum merepresentasikan identitas maupun nilai konservasi secara menyeluruh. Untuk itu, penelitian ini menggunakan metode Research and Development (RD) dengan model pengembangan ADDIE, yang dibatasi pada tahap analisis kebutuhan dan desain. Data dikumpulkan melalui observasi, wawancara dengan pengelola SCI, serta dokumentasi visual kegiatan. Analisis kebutuhan ditinjau dengan konsep STP (Segmentasi, Targeting, Positioning), yang menunjukkan bahwa target utama SCI adalah wisatawan individu dengan minat pada wisata edukatif dan konservasi, sementara target sekunder mencakup perusahaan dan lembaga pendidikan. Berdasarkan hasil analisis, dirancanglah SCIMagz, E-Magazine interaktif yang menyajikan profil SCI, program konservasi, wisata edukatif, hingga testimoni dan penghargaan. Desain dikembangkan menggunakan Canva Pro dan ditampilkan secara interaktif melalui platform digital, dengan visual yang menonjolkan tema bahari dan keberlanjutan. Hasil perancangan menunjukkan bahwa SCIMagz dapat menjadi media promosi yang lebih menarik, informatif, dan terintegrasi dibandingkan strategi promosi sebelumnya. Penelitian ini memberikan dasar bagi pengembangan lebih lanjut melalui uji kelayakan dan implementasi nyata agar SCIMagz berfungsi optimal sebagai sarana promosi wisata bahari berbasis konservasi.Kata Kunci: Wisata Bahari, Smiling Coral Indonesia, E-Magazine, Promosi Digital, Konservasi LautABSTRACTThis study focuses on the design of an interactive E-Magazine as a digital promotional medium for Smiling Coral Indonesia (SCI), a conservation group based on Pramuka Island, Kepulauan Seribu. SCI has relied on social media and digital brochures; however, the content presented remains general, limited, and has not fully represented its identity or conservation values. Therefore, this research employs the Research and Development (RD) method with the ADDIE development model, limited to the needs analysis and design stages. Data were collected through observation, interviews with SCI managers, and visual documentation of activities. The needs analysis was reviewed using the STP (Segmentation, Targeting, Positioning) concept, which indicated that SCI’s primary target is individual tourists interested in educational and conservation tourism, while the secondary target includes companies and educational institutions. Based on the analysis, SCIMagz was designed as an interactive E-Magazine presenting SCI’s profile, conservation programs, educational tourism, as well as testimonials and achievements. The design was developed using Canva Pro and displayed interactively through digital platforms, highlighting marine and sustainability themes. The design results demonstrate that SCIMagz can serve as a more engaging, informative, and integrated promotional medium compared to previous strategies. This research provides a foundation for further development through feasibility testing and real implementation to ensure that SCIMagz functions optimally as a promotional medium for conservation-based marine tourism.Keywords: Marine Tourism, Smiling Coral Indonesia, Interactive E-Magazine, Digital Promotion, Marine Conservation

Pufferfish are the only marine organisms that have the potential to produce secondary metabolites. The purpose of this research is to analyze the comparisonof eluent solutions and optimal fractions to determine the secondary metabolite compounds of flavonoids in the flesh of the pufferfish Arothron manilensis. The research method was carried out using Phytochemical Screening and Thin Layer Chromatography (TLC) methods to detect secondary metabolites. Research results showed that the determination of the eluent, the polarity of the eluent, and the reagents used greatly affect the appearance of the secondary metabolite compound profile. In the ethyl acetate fraction, the secondary metabolite flavonoid compound is the most prominent, while in the n-hexane fraction, the flavonoid compounds are not visible. The content of secondary metabolites in puffer fish (Arothron manilensis) contains flavonoid compounds. The content of flavonoid secondary metabolites in puffer fish A. manilensis showed an Rf value of 0.5-0.975 which has potential as an antioxidant. High Performance Liquid Chromatography (HPLC) testing is needed again, to separate the secondary metabolite compound molecules in a minimum time.Keywords: Arothron manilensis, Flavonoids, Phytochemical Screening, TLC

Penambahan agar dalam pembuatan edible film berbasis tepung tapioka bertujuan agar edible film yang dihasilkan memiliki karakteristik yang sesuai. Penelitian ini bertujuan mengetahui konsentrasi agar terbaik sebagai polisakarida tambahan untuk memperbaiki nilai kuat tarik pada edible film berbahan tepung tapioka.  Perlakuan yang diberikan berupa perbedaan konsentrasi agar, yaitu P1= 0,12%, P2= 0,14%, dan P3= 0,16%. Karakteristik yang di uji berupa ketebalan, water vapor transmission rate (WVTR), kuat tarik, kadar air, dan kelarutan. Data yang diperoleh dianalisis dengan sidik ragam satu arah (ANOVA). Hasil penelitian menunjukkan perbedaan konsentrasi agar pada edible film berbeda nyata terhadap ketebalan sebesar 0,042-0,52 mm, kuat tarik sebesar 15,39-21,43 MPa, tetapi tidak berbeda nyata terhadap water vapor transmission rate (WVTR), kadar air, dan kelarutan. Formulasi P3 menghasilkan karakteristik edible film terbaik. Perlakuan ini menunjukkan kuat tarik tertinggi (21,43 MPa), WVTR terendah (3,84 g/m²/hari), serta nilai ketebalan, kadar air, dan kelarutan yang masih dalam batas ideal karakteristik edible film. Hasil penelitian ini menunjukkan bahwa kombinasi tepung tapioka dan agar memiliki potensi untuk dikembangkan sebagai bahan kemasan ramah lingkungan yang aplikatif pada industri pangan.Kata kunci: kelarutan, ketebalan, kuat tarik, water vapor transmission rate (WVTR)ABSTRACTTapioca flour, a hydrocolloid substance utilized in the production of edible films, possesses limited gelling capabilities and is prone to tearing; hence, the addition of agar (Gelidium sp.) is required. The addition of agar in the process of making tapioca flour-based edible films aims to ensure that the edible film possesses the desirable qualities. This research aims to determine the optimal concentration of agar as an additive polysaccharide to improve the tensile strength of edible films made from tapioca flour. The given treatments consisted of varying agar concentrations: P1 = 0.12%, P2 = 0.14%, and P3 = 0.16%. The evaluated characteristics included thickness, water vapor transmission rate (WVTR), tensile strength, moisture content, and solubility. The data obtained were analysed using one-way ANOVA (analysis of variance). The research results showed that different agar concentrations in edible films significantly affected thickness (0.042-0.52 mm) and tensile strength (15.39-21.43 MPa), but did not significantly affect water vapour transmission rate (WVTR), moisture content, and solubility. Formulation P3 produced the best edible film characteristics. This treatment showed the highest tensile strength (21.43 MPa), the lowest WVTR (3.84 g/m²/day). Thickness, moisture content, and solubility values were all within the optimal ranges for edible film properties.Keywords: solubility, tensile strength, thickness, water vapor transmission rate (WVTR)

Abstract

ABSTRAKCemaran Escherichia coli (E. coli) pada air baku pembuatan garam dapat menimbulkan berbagai permasalahan yang berdampak pada kesehatan masyarakat dan kualitas produk garam yang dihasilkan. Penelitian ini bertujuan untuk mengetahui kelimpahan bakteriE. coli dalam air baku pada pembuatan garam secara tradisional di Desa Pangarengan Kabupaten Sampang. Terdapat empat sampel yang diuji menggunakan uji pendugaan dengan titik pengambilan sampel pada pintu masuk air laut, kolam penampungan air laut, dan kolam air tua. Pengujian sampel dilakukan menggunakan lima tabung positif dengan dua kali pengulangan untuk  setiap sampel. Perhitungan total bakteri E. Coli menggunakan metode Most Probable Number (MPN) atau Angka Paling Mungkin (APM) 3 seri, yaitu pengamatan pertumbuhan bakteri dalam serangkaian tabung media selektif secara bertingkat, dan memperkirakan jumlah bakteri berdasarkan pola tabung positif menggunakan tabel APM standar 3 seri. Hasil analisis menggunakan metode APM menunjukkan jumlah E. coli pada sampel pintu masuk air laut sebesar 7,5 APN/100 mL  penampungan air laut sejumlah 6,1 APM/100 mL, dan penampungan air tua sejumlah 4,6 APM/mL. Berdasarkan jumlah total bakteri E.coli menunjukkan bahwa air baku pembuatan garam tidak sesuai dengan SNI 01-3553-2006 untuk air minum (2 APM/100 mL). Penurunan APM karena peningkatan salinitas diharapkan dapat menurunkan jumlah total bakteri E. coli pada produk garam yang dihasilkan.Kata Kunci: air baku, Escherichia coli, garamABSTRACTThe contamination of Escherichia coli (E. coli) in raw water used for salt production can cause various issues that impact public health and the quality of the resulting salt products. This study aims to determine the abundance of E. coli bacteria in raw water used for traditional salt production in Pangarengan Village, Sampang Regency. Four water samples were tested using a presumptive test, with sampling points at the seawater intake gate, seawater storage pond, and brine (concentrated seawater) pond. Each sample was analyzed using five positive tubes with two replicates per sample. The enumeration of total E. coli bacteria was conducted using the Most Probable Number (MPN) method, employing a three-series (3-tube) approach, which involves observing bacterial growth in a series of selective media tubes at different dilution levels and estimating bacterial concentration based on the pattern of positive tubes using a standard MPN table (3-tube series). The MPN analysis results showed that E. coli levels in the seawater intake sample were 7.5 MPN/100 mL, in the seawater storage pond were 6.1 MPN/100 mL, and in the brine pond were 4.6 MPN/100 mL. Based on the total E. coli counts, the raw water used for salt production does not comply with the Indonesian National Standard (SNI 01-3553-2006) for drinking water quality, which stipulates a maximum limit of 2 MPN/100 mL. The reduction in MPN values is attributed to increased salinity, which is expected to decrease the total number of E. coli bacteria in the final salt product.Key words: Escherichia coli, raw water, salt

Abstract

ABSTRAKPraktik Kerja Lapangan (PKL) ini dilaksanakan di Desa Parang, Karimunjawa, pada 18 November–18 Desember 2024 dengan tujuan mengidentifikasi potensi sektor pariwisata melalui aspek 3A (Atraksi, Amenitas, dan Aksesibilitas). Metode yang digunakan adalah observasi lapangan, partisipasi langsung, wawancara, serta studi literatur dengan sumber data primer dan sekunder. Hasil kegiatan menunjukkan bahwa Desa Parang memiliki daya tarik wisata alam berupa pantai, spot snorkeling dan diving, serta atraksi budaya berupa makam keramat kunci. Dari segi amenitas, desa telah menyediakan homestay, instalasi air bersih, dan infrastruktur dasar meskipun fasilitas penunjang wisata masih terbatas. Aksesibilitas menuju desa hanya dapat ditempuh melalui jalur laut dengan jadwal terbatas, sedangkan akses internal menuju lokasi wisata masih minim penunjuk arah dan infrastruktur jalan. Selain itu, Desa Parang memiliki potensi ekonomi kreatif melalui produk olahan lokal seperti kerajinan kayu, pongblosok, mete, kerupuk samier, dan sirup jambu mete. Analisis berdasarkan pedoman pariwisata berkelanjutan menunjukkan bahwa sebagian instrumen pendukung, seperti organisasi pengelola wisata dan media sosial desa, sudah tersedia, namun masih banyak aspek yang perlu dikembangkan, seperti website desa wisata, paket wisata, data kunjungan wisatawan, dan sertifikasi CHSE. Dengan pengelolaan yang tepat, Desa Parang berpotensi menjadi destinasi wisata bahari unggulan yang berkelanjutan dan mampu meningkatkan kesejahteraan masyarakat lokal.Kata Kunci: Desa Parang, pariwisata bahari, aspek 3A, ekonomi kreatif, pariwisata berkelanjutanABSTRACTThis internship (PKL) was carried out in Parang Village, Karimunjawa, from November 18 to December 18, 2024, aiming to identify tourism potential through the 3A aspects: Attractions, Amenities, and Accessibility. The methods applied were field observation, direct participation, interviews, and literature study using primary and secondary data. Findings show that Parang Village offers natural attractions such as beaches, snorkeling and diving spots, and a cultural attraction in the form of the Keramat Kunci grave. Amenities include homestays and clean water supply, although other supporting facilities remain limited. Accessibility is only possible by sea with restricted schedules, while internal access still lacks adequate infrastructure and signage. The village also has creative economy products such as woodcrafts, pongblosok, cashew nuts, samier crackers, and cashew syrup. Based on sustainable tourism guidelines, some instruments—such as tourism management groups and social media—are already available, while others, including a tourism website, tour packages, visitor data, and CHSE certification, are still lacking. With better management and strategic development, Parang Village has strong potential to become a sustainable marine tourism destination that improves community welfare.Keywords: Parang Village, marine tourism, 3A aspects, creative economy, sustainable tourism

Abstract

ABSTRAKPenelitian ini bertujuan merancang scrapbook tematik Jejak Bahari sebagai media kreatif yang menggabungkan dokumentasi perjalanan, narasi visual, dan edukasi wisata bahari di Smiling Coral Indonesia, Pulau Pramuka. Dengan pendekatan Research and Development (RD), tahapan perancangan meliputi pra-produksi, desain visual, produksi fisik, hingga uji persepsi wisatawan. Data dikumpulkan melalui observasi, dokumentasi, serta kuesioner daring kepada 45 responden. Hasil penelitian menunjukkan mayoritas responden memberikan penilaian positif terhadap aspek desain, isi, hingga fungsi scrapbook, dengan dominasi kategori setuju dan sangat setuju pada indikator yang diukur. Scrapbook fisik dinilai lebih interaktif, personal, dan mampu membangkitkan kembali kenangan wisata dibanding media konvensional seperti brosur maupun dokumentasi digital yang cenderung statis dan jarang diakses kembali. Secara praktis, scrapbook dapat dimanfaatkan sebagai media promosi pariwisata alternatif yang lebih personal sekaligus souvenir eksklusif. Rekomendasi penelitian lanjutan mencakup uji coba dengan responden yang lebih luas, pengembangan scrapbook digital, dan penerapannya pada destinasi wisata lain.Kata Kunci: Wisata Bahari, Scrapbook, Pulau Pramuka, Smiling Coral IndonesiaABSTRACTThis study aims to design a thematic scrapbook "Jejak Bahari" as a creative medium that combines travel documentation, visual narratives, and marine tourism education at Smiling Coral Indonesia, Pramuka Island. Using a Research and Development (RD) approach, the design stages included pre-production, visual design, physical production, and tourist perception testing. Data were collected through observation, documentation, and an online questionnaire from 45 respondents. The results showed that the majority of respondents gave positive assessments of the design, content, and function of the scrapbook, with a predominance of agree and strongly agree categories for the measured indicators. Physical scrapbooks were considered more interactive, personal, and able to evoke travel memories compared to conventional media such as brochures or digital documentation, which tend to be static and rarely accessed. Practically, scrapbooks can be used as an alternative, more personal tourism promotion medium as well as an exclusive souvenir. Recommendations for further research include trials with a wider range of respondents, the development of digital scrapbooks, and their application to other tourist destinations.Keywords: Marine Tourism, Scrapbook, Pramuka Island, Smiling Coral Indonesia
