Indonesia is one of the world's richest nations in terms of its biodiversity. One of the biological resources that has an important role in marine life is macroalgae. As a primary producer, macroalgae play an important role in the coastal environment. Porok Beach is a beach in the Gunungkidul district of Yogyakarta, Java Island, Indonesia. Porok beach is dominated by a rocky substrate, which would be the ideal substrate for macroalgae. The development of coastal areas as a tourism destination is feared to have an impact on macroalgae biodiversity. Comprehensive efforts are required to protect the coastlines of Porok Beach as sources of macroalgae germplasm that will ensure the survival of coastal biodiversity in Gunungkidul. So, it is necessary to study macroalgae diversity in Porok Beach to obtain a preliminary data to conserve. the macroalgae in the area. This study aims to monitor the presence of the macroalgae on Porok Beach. Purposive random sampling was used in the study, which took place on October 17th, 2020. Water temperature and pH are the ecological parameters that are measured. Seaweed specimens were collected only from those that were attached to the substrate (no floating specimens were collected) during low tide and then placed in ziplock plastic bags. Macroalgae species were identified to determine macroalgae species based on taxonomic keys using FAO species identification Guide for Fishery From the results of the study, Porok Beach was home to 17 species of macroalgae, eight of which were classified as Chlorophyta, 3 species are classified as Phaeophyta, and 6 species are classified as Rhodophyta.

Information on genetic relationship amongst teak (Tectona grandis Linn.f) populations in Indonesia is important, in order to maintain the high genetic diversity of the species and to ensure the origin of commercial planting materials. In this study, 94 loci from 25 RAPD primers were used for analyzing genetic diversity and genetic relationship among 30 populations of teak which collected from provenance trial in Bojonegoro and its populations in Sulawesi. Mean genetic diversity (h) of the 30 populations was 0.184, and mean genetic distance between populations (D) was 0.441. Based on cluster analysis, 30 populations of teak were divided into 3 groups. The first group consisted of Burma, the second group consisted of Jawa, India, Indochina and Thailand populations, and the third group consisted of all populations in Sulawesi. High genetic distance between Jawa’s and Sulawesi’s populations can be used to differentiate seed/seedling from both regions.

Pummelo (Citrus maxima) is one of three biotypes considered as true species within the genus Citrus.A major issue of pummelo taxonomy in Indonesia is the high number of cultivars showing variability inphenotypic characters but of unknown genetic diversity. In this study, the assessment of genetic variabilityand taxonomic affi nity of local accessions of C. maxima from Yogyakarta was examined based on RAPDfi ngerprinting. The availability of universal primers and technical simplicity makes RAPD as a molecular toolof choice for the assessment of genetic variability at various taxonomic levels. In this study, 13 accessions of C.maxima collected from Yogyakarta were observed for their genetic variability. An additional three registeredcultivars were included for comparative purpose. Two decamer primers used for the amplifi cation of DNAproduced 222 bands with 174 of them were polymorphic. The data was subjected to cluster analysis to observethe grouping of accessions and taxonomic affi nity. Results indicated high genetic variability among accessions.The dendrogram constructed using UPGMA method based on simple matching coeffi cient showed twomain clusters were which was in line to morphological characters. The grouping of accessions showed cleardifferentiation between accessions bearing white and those with reddish fruit fl esh, and thus demonstratestaxonomic value of this study in recognizing important agronomic character for this tropical fruit crop.

Excessive consumption of fatty foods can lead to hyperlipidemia, which is often coupled with hypertriglyceridemia (HTG), a condition where blood plasma triglyceride (TG) levels elevated beyond normal levels. This condition may disturb physiological functions of the body, such as reproductive functions, and other physiological imbalances leading to chronic stress and depression. Ulva lactuca is a potential natural treatment for HTG, as it contains various nutrients to aid physiological functions. This seaweed also has high levels of Cd, which can increase depression. Therefore, research on the potential benefits of U. lactuca should be followed by an investigation of its health risks. This research aimed to examine the effects of HTG and treatment with U. lactuca on reproduction and depressive-like behavior of male Wistar rats (Rattus norvegicus Berkenhout, 1769). The data collected in this research include body weight, serum TG concentration, gonadosomatic index (GSI), serum testosterone concentration using competitive ELISA, and depressive-like behaviors assessed using the Forced Swim Test (FST) and Open Field Test (OFT). Data were analyzed using One-Way ANOVA followed by DMRT, independent- and paired-samples t-test, and Kruskal-Wallis H test with a significance value of α=0.05. Body weight, serum TG and testosterone concentration, GSI, and depressive-like behaviors were increased by the HTG condition. Ulva lactuca at the1500 mg/kg BW/day did not significantly affect body weight, testosterone concentration, and depressive-like behaviors of HTG rats. Meanwhile, this treatment significantly increased the GSI and depressive-like behaviors of healthy rats. These results suggest that Ulva lactuca treatment not only enhances gonad growth and development but also increases depressive-like behaviors.
