The study of Balanophora in South Sumatra has been carried out from July-August 2018. This research uses the direct observation and collection method in 3 km long track in the Bukit Jambul Gunung Patah Protection Forest Area, South Sumatra. Sample identification was carried out in the Biology Department of the Faculty of Mathematics and Natural Sciences, Sriwijaya University. The results show that there is one Balanophora species, B. elongata. There are 2 subspecies of this species, namely B. elongata var. elongata and B. elongata var. ungeriana (Valeton) B. Hansen. The difference between these 2 subspecies is var. ungeriana in the tubers is not elongated with longitudinally coarse luruk leaves. At that location only found species of B. elongata var. ungeriana. Distribution: Peninsula Malaysia, Borneo, Sumatra, Java, and mostly in West Java for subsp. ungeriana is only recorded on the island of Java precisely at Mount Salak and Mount Gede in West Java. This species is the first record for the Sumatra Island. There are around 30 individual species of B. elongata var. ungeriana respectively 23 female individuals and 7 male individuals. Bulbs, leaf characters and flower types are important to identifying the species of Balanophora. Most of these species are found in habitats where they have a height of 1000-2800 meters above sea level which are suitable for habitat in the Bukit Jambul Gunung Patah Protection Forest Area.

The potential for the carbon content of mangrove forests is four times greater than other forest, this important information needs to be measured to determine the value of carbon stocks at a given time and their changes. The research was done in November 2018-March 2019 in Berbak and Sembilang National Park, Banyuasin, South Sumatra, in each location three transect lines were determined perpendicular to the land as far as 100 m and made 5 plots of 10 x10 m with a distance between plots of 10 m on each transect. The aims are to determine species richness, biomass value, estimated stored carbon reserves, and CO2 uptake in Bruguiera spp. stands. Analysis of comparison of the results of data using descriptive statistical analysis. Based on the results of the study found 4 types of Bruguiera spp. that is Bruguiera cylindrica, Bruguiera parviflora, Bruguiera gymnorrhiza, and Bruguiera sexangula. The total value of the biomass of 410,01 ton/ha, carbon stocks estimation of 189,02 ton C/ha, and the CO2 uptake of 693,69 ton CO2/ha. The results of a statistic descriptive analysis of estimated carbon stocks and CO2 uptake, in Barong Kecil river where of the most areas has been deforested into ponds, have the lowest value than the other research locations like Solok Buntu and Bungin river, with sequential carbon values of 11,51 ton C/ha in Barong Kecil river, 227,66 ton C/ha in Bungin river, and 327,88 ton C/ha in Solok Buntu river, and CO2 uptake of 42,23 ton CO2/ha in Barong Kecil river, 835,52 ton CO2/ha in Bungin river, and 1.203,33 ton CO2/ha in Solok Buntu river.

The initial phase of the fish life cycle is a critical phase associated with high mortality due to sensitivity to predators, food availability, and also environmental changes that occur in nature. Disruption of the initial stages of fish life has a negative impact on fish populations. Until now there has been no information about fish larvae around the Banyuasin River Estuary. Therefore, research is needed on the diversity of fish larvae around the Banyuasin River Estuary, South Sumatra Province. This research were used purposive sampling method, sampling technique in the form of Cruise Track Design with continuous parallel survey trajectory. Based on the results of the study found as many as 10 families consisting of 1483 individuals of fish larvae in March and 1013 individuals of fish larvae in May consisting of Engraulidae 1,601 individuals of fish larvae, Mungiloidei as many as 109 individuals, Leiognathidae 50 individuals, Chanidae 453 individuals, Scatophagidae 20 individuals , Belonidae 39 individuals, Gobioididae 5 individuals, Chandidae 183 individuals, Syngnatihidae 6 individuals, and Gobiidae 30 individuals fish larvae. The index value of fish larvae diversity is classified as medium category (March 1.02 and May 1.12), Morisita index shows the distribution pattern of fish larvae classified as a group (March 0-14.17 and May 2.43-10.40 ), and the evenness index value is in the medium category (March 0.437 and May 0.521).

INNOVATION OF SINBIOTIC FORMULA FOR THE GROWTH OF WHITE SHRIMP LARVAE (Litopenaeus vannamei) Sumardi, Sumardi; Nugroho Ekowati, Christina; Linirin Widiastuti, Endang; Rohmawati Bareta, Ainun; Sarno, Sarno

In the hatchery of white shrimp larvae, there are some problems, such as a decreased water quality and diseases caused by bacteria which cause a decrease in shrimp growth. The solution to reduce these problems is by applying synbiotics. This research aimed to make an innovative synbiotic formula for the absolute length growth and survival rate of white shrimp larvae (Litopenaeus vannamei) as well as the total number of bacteria and the number of Vibrio sp. In this study, there were four treatments, as follows: C-: negative control (without synbiotic application) C+: positive control (commercial synbiotic) P: probiotic 2.5 x 105 cfu/ml and prebiotic 1,5 ppm Q: probiotic 5 x 105 cfu/ml and prebiotic 1 ppm R: probiotic 7,5 x 105 cfu/ml and prebiotic 0,5 ppm S: probiotic 106 cfu/ml and prebiotic 2 ppm, each treatment with four repetitions. This research was set up in a completely randomized design experiment using twenty-four plastic tanks with 50 L total volume filled with 20 L sterile sea water and stocked with 4,000 nauplii in the PT. Citra Larva Cemerlang hatchery, Kalianda, Lampung. Variables observed in this research were survival rate, absolute length growth, total bacterial and Vibrio sp. counts, and water quality in the white shrimp larvae (Litopenaeus vannamei). The results showed that the best survival rate is in treatment S (probiotic 106 cfu/ml and prebiotic 2 ppm) (87.7%), the highest absolute length growth is in treatment P (3.8 mm), the highest total bacteria was in treatment S (11.1 log cfu/ml), and the best total Vibrio sp. is in treatment S (3.5 log cfu/ml). Water quality of the six treatments shows results that are still in normal conditions following Indonesian National Standard SNI 7311: 2009.

Forest and land fires are Indonesia's biggest problem which has continued from 2014 to the present. The number of activities to find the best solution in fire is something that has been done until now. Various methods, both preventive and repressive, have been implemented to prevent forest and land fires from occurring. This research aims to be a sureextinguishing gel, namely hydrogel, which can be used in efforts to extinguish forest and land fires. Extinguishing forest and land fires using hydrogel is a new method that is expected to prevent forest and land fire zones from spreading. This research shows that the tendency of decreasing the average water content of peat due to the drying process based on different intervals of oven time, namely the lowest yield ranged from 61.25% to the highest with a water content of 109.57%.

The escalating contamination of heavy metals such as lead (Pb), zinc (Zn), and copper (Cu) in wetland ecosystems poses a significant threat to environmental integrity and public health. This study aims to assess the phytoremediation potential of purun tikus (Eleocharis dulcis) for the accumulation and reduction of these heavy metals in contaminated sediment and water matrices. An experimental approach was employed wherein purun tikus specimens were cultivated for 20 days in media artificially contaminated with varying concentrations of Pb (5, 10, 15 mg/L), Zn (80, 90, 100 mg/L), and Cu (80, 90, 100 mg/L). There was no significant difference (p > 0.05) in the accumulation of heavy metals Pb, Zn, and Cu in the roots, stems, and leaves of purun plants between treatment times of 5, 10, 15, and 20 days. The duration of treatment did not significantly affect the ability of purun plants to accumulate these heavy metals. The descriptive differences seen although not statistically significant are likely due to the small sample size and high variability of the data. The highest removal efficiencies were observed for Pb in stems (95.97%), Zn in roots (81.59%), and Cu in stems (66.10%). These findings indicate that purun tikus exhibits selective metal uptake and distribution mechanisms coupled with high tolerance to heavy metal stress, affirming its efficacy as a phytoremediator for rehabilitating heavy metal-contaminated wetlands and supporting sustainable ecosystem management.
