Abstract

ABSTRAKPlankton merupakan organisme perairan yang keberadaannya dapat menjadi bioindikator perubahan kualitas biologi perairan. Plankton memiliki peran penting dalam mempengaruhi produktivitas primer perairan laut khususnya fitoplankton. Fitoplankton merupakan mikroorganisme authotroph sehingga dapat membuat makanannya sendiri dengan cara fotosintesis. Dengan demikian, fitoplankton di perairan dapat dijadikan sebagai petunjuk untuk mengetahui kondisi atau kualitas dan tingkat pencemaran suatu perairan. Tujuan dari penelitian ini adalah untuk mengetahui kualitas dan tingkat pencemaran pada air laut sumber utama pembuatan garam di tambak garam UTM. Metode yang digunakan adalah menghitung kelimpahan dan indeks saprobitas sebagai acuan dalam menentukan tingkat pencemaran dengan waktu pengambilan sampel pada pagi, siang serta malam. Berdasarkan hasil perhitungan kelimpahan fitoplankton pada setiap titik pengambilan sampel 15.000 ind/l yang tergolong eutrofik yaitu perairan memiliki tingkat kesuburan yang tinggi. Tingkat pencemar perairan sesuai dengan indeks saprobitas tergolong sedang β/α-mesosaprobik pada sampel siang hari dan ringan β -mesosaprobik pada sampel pagi dan malam hari.Kata kunci : Fitoplankton, Indeks saprobitas, Tambak Garam UTMABSTRACKPlankton are aquatic organisms whose presence can be a bioindicator of changes in the biological quality of waters. Plankton has an important role in influencing the primary productivity of marine waters, especially phytoplankton. Phytoplankton are autotroph microorganisms that can make their own food by photosynthesis. Thus, phytoplankton in the waters can be used as a guide to determine the condition or quality and level of pollution of a waters. The purpose of this study was to determine the quality and level of pollution in seawater, the main source of salt production in UTM salt ponds. The methodused is to calculate the abundanceof phytoplankton and saprobity index as a reference in determining the level of pollution by sampling time in the morning, afternoon and evening. Based on the calculation of the abundance of phytoplankton at each sampling point 15,000 ind/l which is classified as eutrophic, the waters have a high level of fertility. The water pollutant level according to the saprobity index was classified as moderate β /α-mesosaprobic in the daytime sample and light β -mesosaprobic in the morning and evening samples.Keyword: Phytoplankton, Saprobity Index, Salt Pond UTM

Abstract

Gili Labak Island is one of the marine tourism destinations in Sumenep Regency that has a coastal ecosystem vulnerable to the pressures of tourism activities. The increase in the number of tourists without proper environmental management has caused damage to coral reefs and coastal erosion. This condition has reduced the quality of the environment and the beauty of the coastline. Conservation efforts through coral transplantation and casuarina tree planting are needed to maintain the sustainability of the ecosystem and tourism. In an effort to maintain the sustainability of this ecosystem, the “spider” frame is one of the most reliable transplantation methods due to its adaptive structure and efficient support for coral growth. The activities were carried out with the involvement of the community, students, and the village government. The methods used included environmental education, coral transplantation using spider frames, and the planting of 100 casuarina seedlings as an effort to rehabilitate the coastal ecosystem and sustainable tourism. These community service activities went well according to plan. Ten spider frames were successfully installed in shallow waters for coral transplantation, while one hundred casuarina seedlings were planted in coastal areas prone to abrasion. The active participation of the community, the supervisory group (Pokmaswas), and students from SMP Negeri 2 Saronggi contributed to the success of the activity. The coastal environment looks cleaner after the beach clean-up. This activity demonstrates the integration of marine and terrestrial conservation in supporting sustainable marine tourism management. With improved conditions, it is hoped that this will increase the number of tourists visiting and the economic level of the community on Gili Labak Island.

Abstract

ABSTRAKMikroalga Thalassiosira sp. merupakan sumber bioaktif yang potensial karena kandungan protein, lipid, dan karbohidratnya tinggi. Penelitian ini bertujuan untuk mengevaluasi pengaruh perbedaan media kultur untuk peningkatan biomassa dan nutrisi. Rancangan Acak Kelompok (RAK) dengan tiga perlakuan dan tiga ulangan digunakan, dengan analisis proksimat meliputi kadar air, lemak, abu, protein, dan karbohidrat. Data dianalisis menggunakan One-Way ANOVA dan dilanjutkan dengan Uji Tukey HSD untuk mengetahui perbedaan antar perlakuan. Hasil analisis menunjukkan perbedaan signifikan antar media (p 0,05). Kandungan protein tertinggi terdapat pada media air laut steril (PA) sebesar 30,42%, lemak tertinggi pada media air laut tidak steril (PC) sebesar 24,33%, dan abu tertinggi pada media air buatan (PB) sebesar 2,44%. Temuan ini mengindikasikan bahwa media air laut steril (PA)memberikan kecenderungan paling efektif dalam peningkatan  kandungan nutrisi, khususnya protein, pada Thalassiosira sp. tanpa mengabaikan peran media lain dalam mempengaruhi kandungan nutrisi yang berbeda. Oleh karena itu, pemilihan media kultur perlu disesuaikan dengan tujuan produksi biomassa atau komponen  nutrisi yang diinginkan.Kata Kunci: Thalassiosira sp., nutrisi, media kulturABSTRACTThalassiosira sp. microalgae are a potential source of bioactive compounds due to their high protein, lipid, and carbohydrate content. This study aimed to evaluate the effect of different culture media on biomass production and nutrient composition. A Randomized Block Design (RBD) with three treatments and three replications was applied. Proximate analysis included moisture, lipid, ash, protein, and carbohydrate contents. Data were analyzed using One-Way ANOVA followed by Tukey’s HSD test to determine significant differences among treatments. The results showed significant differences among culture media (p 0.05). The highest protein content was found in sterile seawater medium (PA) at 30.42%, the highest lipid content in non-sterile seawater medium (PC) at 24.33%, and the highest ash content in artificial seawater medium (PB) at 2.44%. These findings indicate that sterile seawater medium (PA) tends to be the most effective in enhancing nutrient content, particularly protein, in Thalassiosira sp., while other media contribute differently to specific nutrient components. Therefore, the selection of culture media should be adjusted according to the intended biomass production or targeted nutritional components.Keywords: Thalassiosira sp., nutrition, culture media
