A study on identication of plants species available on Derawan Island, Berau Regency, East Kalimantan has been conducted based on exploration survey around the island between 2002-2005. The plants whicht have observed were then listed on a table, their scientific names wrre recorded, their status (whether being protected or not) were determined, and the benefits or use of the plants were also listed. From this study it can be found 45 species of 30 families. They may bring benefits for the locals as vegetables, source of medicine, providing shady spots, or decorative plants.

Mangosteen rind has a benefical compounds liked xanthone which consisting of mangostin, mangosterol, mangostinon A and B, trapezifolixanthone, tovophyllin B, alpha and beta mangostin, garcinon B, mangostanol, gartanin, and flavonoid epikatekin that known contain an antibacterial and antidiare agent. Escherichia coliis an opportunistic bacterium that is commonly found in the human colon as a normal flora. Its unique because it can cause primary infection in the intestine such as diarrhea in children, as well as its ability to cause infection in other body tissues outside the intestine.This research was done from December 2016 to March 2017. The methods that used in this research were well diffusion test to know the inhibitory power by measuring the clear zone formed. measure the clear zone of mangosteen rind against Escherichia coli. Then to testing extract compounds, there was used phytochemicals screening test. Data there has been found will be analyzed through analysis of variance (ANOVA). In the inhibitory test of ethanol extract from mangosteen rind (G. mangostana L.), it was so effective to inhibit the growth of Escherichia coli through in-vitro test with a resistivity of 1,58 cm and categorized as a strong inhibitory, which MIC from mangosteen rind against Escherichia coli was 3,9% and the compounds that contain in ethanol extract from mangosteen rind (G. mangostana L.) were alkaloid, phenolik, flavonoid, saponin and terpenoid.

Jenis Colletotrichum acutatum merupakan jamur patogen penyebab penyakit antraknosa pada tanaman budidaya, salah satunya tanaman cabai. Pengendalian penyakit antraknosa umumnya menggunakan pestisida sintetis. Penggunaan pestisida sintetis secara terus menerus dapat menimbulkan efek samping yang merugikan, sehingga diperlukan senyawa lain untuk mengendalikan jamur patogen tersebut salah satunya melalui penggunaan fungisida nabati. Penelitian ini bertujuan untuk mengetahui efektivitas ekstrak bunga kenanga dalam menghambat pertumbuhan Colletotrichum acutatum dan untuk mengetahui golongan senyawa aktif yang terkandung dalam ekstrak bunga kenanga. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan tujuh perlakuan yaitu P0: kontrol negatif, P1: kontrol positif, P2: konsentrasi ekstrak 1% (b/v), P3: konsentrasi ekstrak 2% (b/v), P4: konsentrasi ekstrak 3% (b/v), P5: konsentrasi ekstrak 4% (b/v), P6: konsentrasi ekstrak 5% (b/v) dengan masing-masing perlakuan diulang sebanyak 4 kali. Parameter yang diamati yaitu terbentuknya diameter zona hambat, diameter koloni, kerapatan spora, dan uji fitokimia ekstrak. Hasil penelitian uji sumur difusi menunjukan zona hambat terbesar terdapat pada konsentrasi 5% (P6) yaitu sebesar 10,05 mm dan zona hambat terkecil pada konsentrasi 1% (P2) sebesar 7,53 mm. Hasil uji koloni menunjukan diameter koloni terkecil pada hari ke-10 terdapat pada konsentrasi 3% (P4) sebesar 7,09 cm dan diameter koloni terbesar pada konsentrasi 1% (P2) sebesar 8,46 cm.

Mangrove forests have important role in coastal ecosystems, for example to overcome marine abrasion, bird nesting sites, forming ecological balance, capturing and localizing sediments, preventing soil acidity and inhibiting sea water intrusion. The success of mangrove reforestation is largely determined by the success in preparing mangrove seedlings. Nursery beds made of bamboo to accommodate 4 species of mangrove seedlings, that are Bruguiera gymnorrhiza, Rhizopora apiculata, Rhizopora mucronata and Rhizopora stylosa with 6 replications and each of 3 individuals of each type. The variables measured were plant height, number of leaves and stem diameter. Statistical analysis with the Costat & Co. program The results showed that the average growth of stem height from the 4 mangrove seedlings measured from 6 -13 MST was 1.5 cm, 1.4 cm, 0.8 cm and 0.7 cm respectively. The average number of leaves from the 4 mangrove seedlings were 0.6, 1.2, 0.6, and 0.6 strands respectively and the average stem diameter of the 4 mangrove seedlings was 0.1 cm. The mangrove seedlings of Rhizopora mucronata and Bruguiera gymnorrhiza species that produced higher growth rates of stem height than others, and Bruguiera gymnorrhiza which produced the highest average number of leaves compared to the other three types.

This aims of the research was to determine the structure and pollen viability of RangdaCoconut (Cocos nucifera L. “Rangda”) stored at different time and temperatures. Pollen sampleswere collected from Gianyar, Klungkung and Negara. The experiment was conducted at theLaboratorium of Forensic and the Laboratorium of Plant Development and Structure, UdayanaUniversity, from October 2012 to January 2013. Pollen structure was analyzed with acetolysemethod, while pollen viability was analyzed in-vitro. The results showed that the structure of thepollen of “Rangda” coconut was circular, media, monosulcate, Subferoidal-Prolat, Sferoidal.Pollen viability of “Rangda" coconut was low (less than 3%). Pollen stored in the freezer has thebest viability, which continually increased until the 2nd weeks, then declined after that, whiepollen viability stored at room temperature tend to decline up to the fourth weeks.Keywords: structure, viability, pollen, time, storage

Lemongrass consists of two types that have many benefits. Its use in research or in processing using its stems alone causes lemongrass leaf waste which can be used as an essential oil and used as an anti-mosquito lotion to reduce the use of chemicals as repellent. The purpose of this study was to determine the yield of lemongrass essential oil, to determine the protective power of each concentration of citronella essential oil in lotion in repelling mosquito bites, and to determine the level of preference for mosquito repellent lotion. The average yield with three repetitions followed by standard deviation (SD) was 0.1% ± 0.0024% b/b. Lotion preparation provides different protection during 6 hours of exposure, namely K- and F1 no protection, F2 for 2 hours, F3 and K+ 4 hours and F4 5 hours. Based on all parameters, the most preferred formulation is F1 and does not give sensitive reactions. Keyword: Aedes aegypti, essential oils, lemongrass, lotions.
