Seaweed naturally grows in substrate of sand, mixing between sand, mud and shell fragments, and also coral. Previous researches stated that there were types of seaweed that able to grow in more than one substrates. The aims of this research was to know the community structure such as diversity, domination, evenness, and similarity of seaweed on various substrates in Permisan beach, Central java. This research used survey method and samples were randomly selected for each substrate with quadrate of 1 x 1 m2. The research found that 20 kinds of seaweeds with biomass for about 4,669 g. Seven kinds of seaweed that grow in sand substrate with biomass for about 0,636 g, 20 kinds of seaweed in coral substrate with biomass for about 2,399 g, and 12 kinds of seaweeds in mixing substrate with biomass for about 1,634 g. Diversity index value in Permisan beach was ranging between 0,064-0,828 and categorized as low. Domination index value was ranging between 0,213-1,193, which means there was dominating variety. Evenness index value was ranging between 0,021-0,276, which means the community was unstable. The highest similarity index value was coral substrate-mixing for about 75%.

A positive energy imbalance results in overweight and obesity. Overweight and obesity are the major risk factors for many diseases, including diabetes, cardiovascular diseases, and mental health. Animal studies suggested that serotonin involves in food intake control. The Banana peel is a potential natural source of serotonin precursor; furthermore, it may influence food intake. This study aimed to determine the effect of banana peel extract on food intake and body weight gain in male Wistar rats. Twenty-four male Wistar rats (8-10 weeks old), were divided into four groups for feeding treatment. All four group were; the control group (C), the banana peel extract dosage of 4 g/kg BW group (T1), the banana peel extract dosage of 8 g/kg BW (T2), and the banana peel extract dosage of 16 g/kg BW (T3). The food intakes were measured daily, while rats body weights were recorded at the beginning and the end of the three days experimental periods. The study found the rats in the T1 group (8.80 ± 2.63) showed no significant difference in food intake compared to C group (10.68 ± 1.89), T2 group (6.65 ± 3.12), and T3 group (5.42 ± 1.59). Rats in the T2 group (p = 0.038) and T3 group (p = 0.005) showed lower food intake significantly compared to control group. After three days of treatment, the T3 group showed a significant decrease in body weight compared to control group (p = 0.008). This study concluded, the administration of banana peel extract dosage of 8 g/kg BW and 16 g/kg BW suppressed food intake, while the dosage of 16 g/kg BW reduced the body weight in male Wistar rats.

Garlic commonly is consumed as medicine to prevent or heal illness or to maintain someone's health. Many societies prefer garlic (Allium sativum) among other herbal remedies for cholesterol treatment. It consists of several types, and one of them is single bulb garlic used to treat hypertension. There has been, however, no published research reporting the toxicological properties of single bulb garlic. The purpose of this study was to determine subchronic toxic effects of single bulb garlic administered to mice using hematological parameters. The experiment parameters were hemoglobin and hematocrit levels, the number of erythrocytes and leukocytes. Male mice (Mus musculus) strain Balb-C were treated with single bulb garlic extract for 28 days with dosage levels of 0% (N ), 0.25% (P1 ), 0.5% (P2 ), 1% (P3 ), and 2% (P4 ). Single bulb garlic showed no effect on hemoglobin and hematocrit levels but increased the number of erythrocyte and leucocyte. We concluded that single bulb garlic did not cause subchronic toxic effects.

This research aimed to determine the effect of the interaction of the dosage with the application model of Trichoderma harzianum bio-fungicide pellet to the effectiveness of damping-off disease control caused by Fusarium sp. on the green mustard, and also to determine the most effective dosage and application model to control that disease. This research was experimental with the factorial completely randomized design. The factors were: the dosage of T. harzianum bio-fungicide pellet, i.e., 0 g (D0), 12,5 g (D1), 25 g (D2), 37,5 g (D3), 50 g (D4), 62,5 g (D5), and 75 g (D6); and the application model of pellet, i.e., T1, T2, T3 dan T4. This research analyzed the data using the test of variety difference with 5% and 1% degree of errors, followed by least significance difference test. The results showed the interaction between dosage and application model did not affect the effectiveness of the damping-off disease control on the green mustard seedling. The dosage of T. harzianum pellets and the application model of T. harzianum pellets independently gave a significant effect on the effectiveness of biological control agent of T. harzianum toward Fusarium sp. on the green mustard seedling. The dosage of 37,5 g per 50 green mustard individuals was the most efficient amount to control the damping-off disease. The 7-day continuous application and incubation of pellet to the seeding medium before pathogen inoculation and planting were better than any other application models.

Sansevieria is an ornamental plant commonly known as mother-in-law's tongue, devil's tongue, and snake tongue. It has many functions e.g. uses as medicine, its fiber for the textile industry, and as indoor air pollutants absorber. However, the growth of Sansevieria is slow. Therefore the supply of it seeds in large quantities in the short time was difficult. The use of Plant Growth Regulator (PGR) was one solution to accelerate the propagation of Sansevieria leaf cuttings. This study aimed to determine the concentration of IBA and the composition of media to increase the leaf cuttings propagation of Sansevieria cylindrica var. patula. The method was randomized block design with factorials. Factor I was the IBA concentrations comprised of K0 at 0 ppm, K1 at 50 ppm, K2 at 100 ppm, K3 at 150 ppm, and K4 at 200 ppm. Factor II was the ratio of manure:sand:rice-husk-ash as the growth media, comprised of M1 with 1:1:1 ratio, M2 with 1:2:1 ratio, and M3 with 1:1:2 ratio respectively. Each with three replicates overall was 45 experimental units. The parameters observed were a percentage of propagated cuttings, the number of roots, the longest length of roots, the number of shoots. The results showed the IBA could not increase the growth of cuttings in all media composition; however media compositions could enhance the number of shoots. The effective media composition propagated the cuttings was the M1 a 1:1:1 ratio of manure:sand:rice-husk-ash.

AbstRactDillenia serrata (Dengen) is an endemic plant from Sulawesi and it has never been known for its benefit, especially as antibacterial herbs. Unripe Dengen’s fruit is enveloped by sepals, thus it is indicated to have antibacterial activity as a protection of fruit from destructive bacteria. This research aimed to determine the optimum inhibitory of Dengen fruit sepals extracts to Escherichia coli and Staphylococcus aureus. Fruit sepals were extracted with two solvents, which are polar and non-polar, namely methanol and n-hexane. The extraction was done by maceration. Compounds from methanol and n-hexane extracts were qualitatively measured using phytochemical test, such as alkaloid, flavonoid, tannin, triterpenoid/steroid, and saponin. Methanol and n-hexane extracts were divided into three concentrations as treatments for antibacterial test namely 30, 60, and 90 % using disk diffusion method with five replications. The result of phytochemical test showed Dengen fruit sepals contained alkaloids, flavonoids, tannins, triterpenoids/steroids and saponins. The extracts showed optimum inhibitory effect to E. coli which was obtained at 90 % of methanol extract with 0.495 cm inhibitory zone diameter. While, the optimum inhibitory effect to S. aureus was obtained at 90 % of n-hexane extract with 0.54 cm of inhibitory zone diameter. Key words: Dengen fruit sepals, antibacterial, maceration, phytochemical, disk diffusion method

Watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai] is a plant of Cucurbitaceae family which is include in an annual plant. In Indonesia, watermelon has diversity in its cultivar as can be seen from the stem, leaf, flower, and fruit morphology. This research is aimed to find out the diversity and the similarity relationship of watermelon cultivar in Nusawungu, Cilacap. A survey method was used in this research by taking the samples with a random sampling technique (purposive sampling). This research parameter consisted of stem, leaf, flower, and fruit morphology of each watermelon cultivar. Data of watermelon cultivar morphology were analyzed descriptively and then analyzed based on the similarity relationship with UPGMA method (Unweighted Pair Group Method with Arithmetic Mean) using the MEGA 5.05 software. The result of this research showed that there were five watermelon cultivars namely C. lanatus ‘Farmers Giant’, C. lanatus ‘Nina’, C. lanatus ‘Black Orange’, C. lanatus ‘Torpedo’, and C. lanatus ‘Bintang’. There were two groups of watermelons based on phenetic analysis namely group I consisting of C. lanatus ‘Torpedo’, C. lanatus ‘Black Orange’, and C. lanatus ‘Nina’ cultivars, group II consisting of C. lanatus ‘Bintang’ and C. lanatus ‘Farmers Giant’. The closest similarity was between C. lanatus ‘Farmers Giant’ and C. lanatus ‘Bintang’ cultivars with the dissimilarity index of 0,516. While the most distantly related was between C. lanatus ‘Nina’ and C. lanatus ‘Farmers Giant’ cultivars with the dissimilarity index of 2,338.

Ecological studies and the spatial distribution of two forest ecosystem, natural forest and mixed forest, on Mount Slamet, Baturaden, Central Java has been done. There are 12 species of palms in natural forests, Calamus asperimus, C. heteroideus, C. javensis, Calamus sp. 1, Calamus sp. 2, Caryota maxima, C. mitis, Daemonorops rubra, Pinanga coronata, P. javana, Plectocomia elongata, and Salacca zalacca. While in the mixed forest were found six species of palm that were C. asperimus, C. ciliaris, Caryota maxima, Pinanga coronata, P. javana, and Plectocomia elongata. The species that had highest Importance Value Index (IVI) in the two types of ecosystems were Pinanga coronata. Pattern of its distribution both in natural and mixed forests have Morisita index value> 0. This value means that palm has a clustered distribution pattern. The highest spatial distribution of natural palm forest was found in 8-15% slopee class and height class 1,100 - 1200 m asl. Whereas for mixed forest it is found mostly in slopee class 8-15% and height class 900 - 1,000 m asl.
