The alteration of Demak Regency's coastal areas caused by the sea rob phenomenon has a significant impact on the mangrove vegetation. The Semarang-Demak toll road construction along Sayung coast potentially causes mangrove damage. The purpose of this study is to determine the structure and profile, and analyze the condition of mangrove vegetation in Sayung, based on the structure and profile of Sayung mangrove vegetation. The study was conducted on the mangroves of Bedono, Mondoliko, and Morosari Village. This research used an exploratory method with descriptive analysis, by collecting data on vegetation parameters and vegetation profiles. The results showed that the types of mangroves found at all observation stations consisted of Avicennia, Bruguiera, and Rhizophora. The profile graph shows an association between Avicennia alba, Avicennia marina, and Rhizophora mucronata. Important Value Index (IVI) for all stations shows that Avicennia officinalis have highest value on 65,30 and 50,18 respectively. Diversity index shows that both stations have value on 0,873 and 0,893 which belongs to low diversity. Similarity index on each sub-stations shows the significant difference between Bedono-A, Bedono-C, Mondoliko, and Morosari stations at 0,4 index, Based on Abiotic parameters such as pH, salinity, and water temperature found on the optimal quality standard level. The conclusion is mangrove vegetation structure dominated by Avicennia and Rhizophora groups, with a low level of diversity at all observation stations.</em></p> 2024-05-30T22:38:14+07:00 ##submission.copyrightStatement## http://journal.unnes.ac.id/sju/UnnesJLifeSci/article/view/71011 Identifikasi Keanekaragaman Famili Kenikir-Kenikiran (Asteraceae) di Kawasan Desa Kawak Pakis Aji Jepara 2024-05-31T15:52:30+07:00 Anang Khoirunni'am Azzarkasyi [email protected] Fitri Widyaningrum [email protected] Hanisa Ayu Afsari [email protected] Nazilatun Ni'mah [email protected] Muhamad Jalil [email protected] <p><em>Indonesia is one of the countries that has the highest level of biodiversity in the world.

This study aims to identify the types of lactic acid bacteria from naturally fermented queen pineapple peels, identified based on phenotypic characteristics. Bacteria isolation was performed using the pour plate method with serial dilution up to 10^-6 using MRSA medium (de Man-Rogosa-Sharpe Agar). Characterization of lactic acid bacteria includes morphological, biochemical, and physiological characteristics. Bacterial identification refers to Bergey’s Manual of Determinative Bacteriology. The isolation and identification results of lactic acid bacteria obtained 6 isolates, namely, BAL1, BAL2, BAL3, BAL4, BAL5, and BAL6. Simple matching coefficient UPGMA analysis showed that BAL1, BAL2, and BAL4 had a phenotypic similarity of 83.8% to Lactobacillus fermentum; BAL3 and BAL5 had a phenotypic similarity of 90.9% to L. plantarum; and BAL6 had a phenotypic similarity of 87.9% to L. brevis. Jaccard coefficient UPGMA analysis indicated that BAL1, BAL2, and BAL4 grouped with L. fermentum with a phenotypic similarity value of 68.1%; BAL3 and BAL5 had a phenotypic similarity of 83% to L. plantarum, and BAL6 had a phenotypic similarity of 73.3% to L. brevis. This suggests that isolates BAL1, BAL2, and BAL4 are suspected members of L. fermentum species, BAL3 and BAL5 are suspected members of L. plantarum species, and BAL6 is suspected as a member of L. brevis species.</em></p> 2024-05-30T22:44:25+07:00 ##submission.copyrightStatement## http://journal.unnes.ac.id/sju/UnnesJLifeSci/article/view/76891 Kadar Leptin Balita Stunting yang Diberi Makanan Tambahan Berbasis Daun Kelor dan Ikan Laut 2024-05-31T15:52:32+07:00 Nirmala Al Fatiah [email protected] Ari Yuniastuti [email protected] Nugrahaningsih WH [email protected] Lisdiana Lisdiana [email protected] <p><em>Leptin plays a role in regulating the growth of bones and other body tissues. Leptin can affect the epiphyseal growth zones in long bones, contributing to height growth. The aim of this research is to analyze leptin levels and body height in toddlers before and after giving additional food based on Moringa leaves and sea fish. The supplementary feeding intervention was carried out for 10 weeks on 30 toddlers with stunted and very stunted nutritional status at the Sedan Community Health Center, Rembang Regency. Leptin levels in the blood were analyzed using ELISA, height measurements were carried out using a stadiometer, determination of nutritional status was guided by the PERMENKES regarding 2020 child anthropometry standards, and data analysis used the SPSS program. The results of the study showed that the average leptin level decreased and the average body height increased after the intervention of providing additional food based on Moringa leaves and sea fish. Thus, it can be concluded that decreasing leptin levels can cause a decrease in fat and adipogenesis which results in increased bone formation in the form of increased height in stunted toddlers at the Sedan Community Health Center, Rembang Regency.</em></p> 2024-05-30T22:47:55+07:00 ##submission.copyrightStatement## http://journal.unnes.ac.id/sju/UnnesJLifeSci/article/view/64386 Karakter Anatomi dan Kandungan Pigmen Daun Mangga Wirasangka (Mangifera indica var.
