Green macroalgae Caulerpa racemosa from the waters of Lemukutan Island was isolated to obtain its endophyte fungi. Endophyte fungi were explored to determine their potential as antibacterial. Isolation of endophyte fungi was carried out by dilution method using PDA media. Endophyte fungi with different morphology were obtained as many as 4 isolates, named CRF1, CRF2, CRF3 and CRF4. Antibacterial activity testing was carried out by agar diffusion method. Endophyte fungi isolate CRF3 showed the best activity against Escherichia coli bacteria while CRF2 isolate showed the best activity against Staphylococcus aureus with inhibition zone diameters of 15.83 mm and 11.99 mm, respectively.

Seagrass is a higher plant (Anthophyta) that lives and grows immersed in the marine environment. Seagrass provides important ecosystem services include coastal protection, carbon absorption for climate change mitigation, nutrient storage for eutrophication mitigation and shelter for small fish, and high biodiversity conservation efforts for iconic endangered species. The current lack of global attention, therefore seagrass research is important to increase knowledge on a local and national scale. Given the extent of seagrass beds and the length of Indonesia's coastline which ranges 95,181 km, so it still needs to understand seagrass more deeply, because this is very important for conservation and restoration. The purpose of this review article is to comprehensively review research on seagrass in Indonesia in five years that expected to provide a future perspective for seagrass research in Indonesia. In the publication regarding seagrass studies in Indonesia, there are 7 categories of topics discussed, distribution and biology, plant physiology, microbial ecology, fauna, impacts and potential, carbon absorption, and restoration. In general, the focus on seagrass research in Indonesia includes seagrass species, seagrass communities, nutrient cycles in seagrass ecosystems, physiology, and the impact of pollution on seagrass habitats. The results presented in seagrass research in Indonesia are still quite descriptive and lagging when compared to studies that have been carried out in developed countries. The developed countries have developed new methods for seagrass restoration activities to new knowledge about seagrass genetics that has never been disclosed previously.

Padang lamun merupakan ekosistem pesisir berfungsi sebagai tempat mencari makanan, berlindung, serta berkembang biak. Perifiton ditemukan melekat pada permukaan daun lamun, dapat menjadi faktor pendukung produktivitas primer tetapi dapat juga mengurangi cahaya yang masuk untuk fotosintesis, sehingga dapat mengurangi komposisi padang lamun. Penelitian ini bertujuan untuk mengetahui komposisi jenis perifiton dan kelimpahan perifiton pada lamun Oceana serrulata di Pulau Panjang dan Pantai Prawean Bandengan, Jepara. Metode penelitian dilakukan dengan menggunakan metode survei. Penentuan lokasi sampling dilakukan dengan metode purposive sampling. Pendataan data kerapatan lamun dilakukan menggunakan metode line transek kuadran. Preparasi sampel daun lamun dilakukan guna mengetahui komposisi perifiton menggunakan metode pengerikan menggunakan kuas dan diamati menggunakan mikroskop. Jenis perifiton yang ditemukan pada daun lamun Oceana serrulata terdiri dari 2 genus (Cyanophyceae) dan 11 genus (Bacillariophyceae). Nilai kelimpahan perifiton pada daun lamun Oceana serrulata di Pulau Panjang dan Pantai Prawean Bandengan adalah 5349,98 ind/cm2 dan 8357,37 ind/cm2. Keberadaan perifiton di Pulau Panjang lebih sedikit dibandingkan dengan Pantai Prawean Bandengan. The seagras ecosystem are coastal ecosystems that function as places to find food, shelter, and breed. Periphyton was found attached to the surface of seagrass leaves, which can be supporting factor for primary productivity but can also reduce incoming light for photosynthesis, thereby reducing the composition of seagrass beds. This study aims to determine the composition of periphyton species and the abundance of periphyton in seagrass Oceana serrulata on Panjang Island and Prawean Bandengan Beach, Jepara. The research method was carried out using a survey method. Determination of sampling locations was determined using a purposive sampling method. Data collection on seagrass density was carried out using the quadrant transect method. Seagrass leaf sample preparation was carried out to determine the composition of periphyton using the scraping method using a brush and observed using a microscope. The types of periphyton found on the leaves of seagrass Oceana serrulata consist of 2 genera (Cyanophyceae) and 11 genera (Bacillariophyceae). Periphyton abundance values in leaves of seagrass Oceana serrulata on Panjang Island and Bandengan Prawean Beach were 5349.98 ind/cm2 and 8357.37 ind/cm2. The presence of periphyton on Panjang Island is less than on Prawean Bandengan Beach.
