Abstract

Marennine is a blue-green pigment produced by diatoms of the Haslea genus, one of which is Haslea ostrearia. This marennine pigment is water-soluble and confirmed to contain polyphenols and glycosides. There are two forms of marennine pigment: the intracellular form of marennine (IMn) and the extracellular form of marennine (EMn). Marennine pigments exhibit various biological activities such as antibacterial, antiviral, antioxidant, allelopathic, and inhibiting the growth of other diatoms. With this biological activity, marennine can be used in various fields, one of which is aquaculture.This research aims to determine the level of toxicity and analyze the effect of exposure to the extracellular marennine produced by H. ostrearia on the juvenile blood clam Tegillarca granosa. By using the toxicity test method, Blue water which is supernatant of H. ostrearia (BW) was tested on juvenile of commercially important bivalve species, the blood clams Tegillarca granosa, with three treatments, namely control (0 mg/L), treatment A (0.25 mg/L) and treatment B (0.5 mg/L of BW). The observation parameters of this study were LC50-72 h with one-way ANOVA analysis. The results showed that the BW produced by H. ostrearia increased the survival of juvenile blood clams T. granosa up to 27.7% in treatment B (0.5 mg/L) compared to control within 72 h. The one-way ANOVA analysis revealed that the control and treatment B (0.5 mg/L) were significantly different. This study shows that there is potential to develop the use of marennine in shellfish aquaculture.

Abstract

This research aims to understand the condition of coral reef (life coral), the abundance of reef target fishes, and the corellation between those two variables. This research has been conducted in Tinabo Besar Island with 6 sampling stations in 5-6 meter depth. Data collected are substrate cover precentage (life form), and the number of reef target fish appeared from 7 specified families (Serranidae, Lutjanidae, Haemulidae, Lethrinidae, Scaridae, Siganidae, and Acanthuridae) using Underwater Photo Transect (UPT) and Underwater Visual Census (UVC). Substrate cover analyzed using CPCe software with life coral, dead coral, algae, abiotic, and other biota cover output. Mortality Index (MI) obtained from the ratio of life coral and dead coral. The result shows that percentage of life coral coverlie between 11.87% to 38.80%, with dominance of Coral Masive (CM). It’s mean that the coral reef condition is in poor to moderate category. Coral death ratio is low with MI between 0.15 to 0.30. Reef target fish total abundance is 493 individual/2100m2 from 31 species, with dominance from Lutjanidae family (173 individual). The result shows positive and strong enough correlation between coral reef coverage and reef target fish abundance (r=0.65) with Determinantion Coefficient at 42.55%. Linear regression is y=-12.929+3.7562x, where in every addition of coral reef cover percentage, resulted in addition of 4 fishes.Keyword: life coral, abundance, reef target fish, correlation, Tinabo Besar Island

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh pendapatan rumah tangga, usia ibu dan pendidikan ibu terhadap angka stunting pada anak. Stunting merupakan masalah kesehatan yang berhubungan dengan malnutrisi kronis pada anak, yang dapat mempengaruhi perkembangan fisik dan kognitif. Faktor-faktor yang dipilih dalam penelitian ini didasarkan pada teori bahwa kondisi ekonomi dan sosial keluarga memiliki dampak signifikan terhadap status gizi anak. Pendekatan kuantitatif digunakan dengan analisis regresi logistik biner. Data yang digunakan dalam penelitian ini diperoleh dari survei terhadap rumah tangga dengan anak balita di wilayah tertentu. Analisis dilakukan menggunakan regresi logistik untuk mengukur pengaruh antara variabel-variabel tersebut. Hasil penelitian menunjukkan bahwa usia ibu 26-35 tahun sebanyak (53%) mengalami stunting. Hal ini karena rentan usia yang tidak memadai dari segi pengetahuan tentang gizi seimbang, rendahnya status gizi ibu hamil.
