Kabupaten Sumba Timur merupakan salah satu daerah dengan sumber daya perikanan yang melimpah, namun saat ini belum terdapat data jumlah konsumsi dan asupan gizi ikan masyarakat pesisir. Tujuan penelitian adalah mengetahui profil konsumsi ikan, angka konsumsi ikan, dan status asupan gizi ikan masyarakat pesisir di Kabupaten Sumba Timur. Penelitian ini dilakukan pada bulan Mei—Juni 2020, di sepuluh desa dan dua kelurahan pesisir. Jumlah responden yang dilibatkan adalah 347 orang, yang dipilih menggunakan metode slovin dengan kriteria usia responden 18—60 tahun dan memiliki preferensi tentang ikan. Pengambilan data profil konsumsi ikan dilakukan dengan wawancara, sedangkan angka konsumsi ikan dan status asupan gizi ikan harian menggunakan instrumen food frequency questionnaires. Data hasil penelitian dianalisis deskriptif dan analisis regresi linier tunggal untuk mengetahui hubungan karakteristik keluarga terhadap jumlah konsumsi ikan (kg/kapita/bulan). Hasil penelitian menunjukkan mayoritas masyarakat pesisir berpendidikan Sekolah Menengah Pertama (SMP) dan bermatapencaharian nelayan. Masyarakat pesisir sebanyak 56,80% mengkonsumsi ikan 2—5 kg/kapita/bulan dan 43,20% mengkonsumsi ikan > 5 kg/kapita/bulan. Angka konsumsi ikan masyarakat pesisir berdasarkan usia dan jenis kelamin adalah 45,62—48,00 kg/kapita/tahun atau setara dengan 118,37—133,45 gram/kapita/hari. Angka konsumsi ini masih rendah dibandingkan target konsumsi ikan nasional tahun 2020, yakni 56,39 kg/kapita/tahun. Kontribusi angka konsumsi ikan terhadap rata-rata status asupan gizi ikan masyarakat pesisir adalah protein 7,53 (gram/kapita/hari), lemak 1,08 (gram/kapita/hari), dan energi 107 (kkal/kapita/hari). Khusus pada status kecukupan protein ikan harian belum memenuhi standar asupan gizi hewani ikan, yakni minimal jumlah asupannya harus mencapai 18,53 gram/kapita/hari. Oleh sebab itu, perlu dilakukan strategi untuk membudayakan konsumsi ikan pada masyarakat melalui sosialisasi, edukasi, dan diversifikasi produk perikanan.Title: Fish Consumption Analysis of East Sumba Coastal CommunitiesEast Sumba Regency is one of the areas with abundant fishery resources. Currently, there is no data on fish consumption and nutritional intake in coastal communities. The purpose of the study was to find the profile of fish consumption, the number of fish consumption, and the nutritional status of fish in coastal communities in East Sumba Regency. This research was conducted in May—June 2020 in ten and two coastal villages. The number of respondents involved was 347. The number of respondents was determined using the Slovin approach with the criteria of the respondent’s age being 18—60 years and having a preference for fish. Data collection on fish consumption profiles was conducted by interview, while fish consumption figures and daily fish nutritional status used the food frequency questionnaire instrument. The research data were analyzed descriptive and single linear regression analysis to decide the relationship of family characteristics to fish consumption (kg/capita/month). The study results show that most coastal communities have a junior high school education, earning a livelihood from fishermen. Coastal communities 56.80% consume fish 2—5 kg/capita/month and 43.20% consume fish >5 kg/capita/month. The fish consumption rate of coastal communities based on age and gender is 45.62—48.00 kg/capita/year or equal to 118.37—133.45 grams/capita/day. This consumption figure is still low compared to the national fish consumption target in 2020, which is 56.39 kg/capita/year. The contribution of fish consumption figures to the average nutritional status of fish in coastal communities is protein 7.53 (grams/capita/day), fat 1.08 (grams/capita/day), and energy 107 (kcal/capita/day). In particular, the daily fish protein adequacy status does not meet the standard of fish animal nutrition intake, namely the smallest amount of intake must reach 18.53 grams/capita/day. Therefore, a strategy is needed to cultivate fish consumption in the community through socialization, education, and diversification of fisheries products.
ABSTRAKRumput Laut atau seaweed merupakan sumberdaya hayati yang potensinya cukup banyak di Sumba Timur. Produksi rumput laut di Sumba Timur mencapai hingga lebih dari 60% dan memiliki produksi rumput laut yang sangat bagus, sehingga menjadi peluang besar untuk pemanfaatannya. Eucheuma cottoni merupakan salah satu rumput laut yang perlu dikembangkan, karena memiliki nilai ekonomis yang tinggi dimana rumput laut Eucheuma cottoni memiliki kandungan metabolit sekunder berupa senyawa bioaktif yang berpotensi sebagai antibakteri, antivirus dan antijamur. Telah dilakukan formulasi sediaan gel antibakteri hand sanitizer (penyanitasi tangan) dari kombinasi dari rumput laut Eucheuma cottoni dan jeruk yang bertujuan untuk memperoleh sediaan gel hand sanitizer yang memiliki aktivitas antibakteri yang dapat diterima oleh masyarakat. Kata kunci: rumput laut; Eucheuma cottoni; gel hand sanitizer. ABSTRACTSeaweed is a potential biological resource in East Sumba. Seaweed production in East Sumba reaches more than 60% and has a very good seaweed production, making it a great opportunity for its utilization. Eucheuma cottoni is one of the seaweed that needs to be developed, because it has a high economic value where the seaweed Eucheuma cottoni contains secondary metabolites in the form of bioactive compounds that have the potential as antibacterial, antiviral and antifungal properties. The hand sanityzer antibacterial gel formulation has been carried out from a combination of Eucheuma cottoni and orange seaweed which aims to obtain hand sanitizer gel preparations that have antibacterial activity that can be accepted by the public. Keywords: seaweed; Eucheuma cottoni; gel hand sanitizer.
Makroalga memiliki metabolit sekunder seperti flavonoid, alkaloid, fenol dan sebagainya, yang sudah banyak dimanfaatkan sebagai obat-obatan. Makroalga atau rumput laut banyak dikenal oleh masyarakat diperoleh dari perairan pantai Londalima yang berada di Kabupaten Sumba Timur, penelitian ini bertujuan untuk mengidentifikasi jenis kandungan senyawa dengan menggunakan analisis uji fitokimia. Metode yang digunakan dalam penelitian ini adalah uji kualitatif dengan beberapa pereaksi seperti reagen mayer, dragendorf dan wagner untuk uji flavonoid, sedangkan pengujian saponin, tanin, alkaloid, fenolik, steroid atau terpenoid menggunakan metode liebermann burchard. Hasil penelitian ini menunjukkan bahwa makroalga Gracilaria corticata teridentifikasi mengandung semua golongan senyawa yang diuji seperti flavonoid, saponin, tanin, alkaloid, fenolik dan steroid/terpenoid, hal berbeda ditunjukan Eucheuma spinosum tidak mengandung saponin, sedangkan Ulva reticulata, Sargassum muticula dan Padina australis mengandung flavonoid dan tanin. Sehingga dapat disimpulkan bahwa makroalga yang ada secara alami dapat dimanfaatkan sebagai bahan obat-obatan disesuaikan dengan kandungan senyawa yang ada.
Seaweeds have an inherent capacity to absorb heavy metals from marine water. This intrinsic ability allows these organisms to accumulate much amount of heavy metals over time. This study conducted at Kupang Village, Jabon Sub-District, Sidoarjo District, where almost 40% of the area consists of Gracilaria sp. ponds cultured. The purpose of this study was to analyze the Pb heavy metals concentration in water culture and its concentration in holdfast and thallus of Gracilaria sp. In this research, determination of samples in each pond was taken on day 0 (before planting), 20 days (Initial Production) and on day 40th (Post/Harvest). The aquatic parameters include salinity, temperature, acidity (pH), and dissolved oxygen (DO). Quantitative determination of heavy metals on sample using Atomic Absorption Spectrophotometry (AAS). Determinations of heavy metal accumulation in organism using Bioconcentratin factor (BCF) and Translocation factor was used to calculate the Pb heavy metal translocation process from the base to the tip of Gracilaria sp. The results of the study showed the highest Pb concentration found in the second sampling age 20 days, in pond 1 with 7.61 ± 0.18 mg.kg -1 , and pond 2 was 5.35 ± 0.09 mg.kg -1 . This concentration has not exceeded the threshold value that might have an effect if more than 8.6 mg.kg -1 . The highest Pb level at the holdfast of Gracilaria sp. found at age 0 days before planting, which is 3.38 ± 0.23 mg.kg -1 and decreases to post-harvest (age of 40 days) which is 0.84 ± 0.00 mg.kg -1 . The Transaction Factor (TF) of Pb heavy metal value from holdfast to thallus is 1,015 thus Gracilaria sp. absorbs heavy metals in high concentrations at the beginning of planting and is able to release it again before harvest time.
