Abstract

ABSTRACTInsects Community on the Flower of Rafflesia patma Blume (Rafflesiaceae) in its Non NativeHabitat of Bogor Botanical Gardens, Bogor City, Province of West Java, Indonesia. The studywas conducted at the Bogor Botanical Gardens, Bogor, West Java, Indonesia using a bloomingfemale flower of R. patma. The insects were directly counted in the morning, noon, and afternoonon both fresh blooming and rotten R. patma . Twenty three insect species were collectedduring the study belonging to the order Coleoptera (2 families, 2 species, 5 individuals),Diptera (9 families, 18 species, 1176 individuals), and Hymenoptera (2 family, 4 species, 13individuals). Number of individuals of each insect species captured were frequently less than1.35% from total captured. There were specialization of flies visiting fresh opening flower andthe rotten one. Six species, Leiomyza laevigata (Asteiidae), Chrysomya megacephala, andHemipyrellia tagaliana (Calliphoridae), Stegana coleoptrata (Drosophilidae), Heteromyzaoculata and Tephrochlamys rufiventris (Heleomyzidae) were predicted as important pollinatorsof R. patma.Key words: Insect community, flower, Rafflesia patma, non native habitat, Bogor BotanicGarden.

Abstract

Previous researchers have investigated the manufacture of lithium battery electrode materials from Li5FeO4 composites with activated carbon of cashew nutshells. However, the effect of combining activated carbon to the lithium battery electrode material was not reviewed. The purpose of this study was to determine the effect of the comparison of the mass composition of Li5FeO4 and cashew nut shell active carbon on the capacitance value of the lithium battery electrode. These electrodes generated using the high-temperature solid-state method. The material used is iron oxide Fe2O3 from iron sand and LiOH.H2O, which homogenized with a sintering temperature of 850ÌŠC for 15 hours with a ratio of 6/1 to produce Li5FeO4. Then Li5FeO4 was compiled with activated carbon of cashew nut shells with a mass fraction of activated carbon 60%, 50%, 40%, and 20%. Furthermore, it characterized using cyclic voltammetry. The results of cyclic voltammetry characterization for a mass fraction of 60% produce a capacitance of 4.7 F / g, a mass fraction of 50% produces a capacitance of 59.1 F / g, a mass fraction of 40% produces a capacitance of 87, 3 F / g, and a mass fraction of 20% produces capacitance of 243 F / g. From the four variations of mass fraction, the capacitance that meets the lithium battery electrode capacitance on the market is the mass fraction of 20%.

Abstract

This study aims to determine the effect of variations of  activation temperature of  activated carbon from sugar palm bunches of chemically activatied with the activation agent of potassium silicate (K2SiO3) on the crystalline structure. Activated carbon is the result of pyrolysis of carbonaceous raw materials at temperatures lower than  of 1000 oC. Activated carbon from bunches of sugar palm acquired in four steps: preparation steps, carbonization steps using the pyrolysis reactor with temperature of 300 oC - 400 oC for 8 hours and chemical activation using of potassium silicate (K2SiO3) activator in weight ratio of 2: 1 and physical activation using the electric furnace for 30 minutes with temperature variation of 600 oC, 650 oC, 700 oC, 750 oC and 800 oC. The crystalline structure tested by X-Ray Diffraction (XRD) method, the results yielded of 26,60o, 26,62o, 26,16o, 26,22o, 26,97o,  and 26,68o respectively. The highest crystalline structure yield was 22.26% at temperature of  600 oC and the lowest was 8.83% at temperature of 650 oC. The results obtained were amorphous  91.17% at the highest temperature of 650 oC and the lowest 77.74% at temperatur of  600 oC  which has a random and irregular arrangement pattern of atoms or molecules repeatedly or not periodically.

Abstract

This study aims to determine the results of students' technological literacy abilities on technical aspects, cognitive aspects and social aspects. The object in this study was class X students on a multimedia expertise program with 100 people. This research uses descriptive-quantitative research methods. The instrument used in this study was a student technology literacy questionnaire. The type of data obtained is quantitative data obtained from the student's technological literacy abilities questionnaire. Data analysis procedures in this study were: (1) calculating the total score from the questionnaire for each student; (2) determine the value of students' technology literacy abilities for each indicator; and (3) categorizing students' technology literacy abilities based on technical, cognitive and social aspects. The results of the technology literacy ability of the tenth grade students of the multimedia expertise program at SMKN 4 Kendari for each aspect, namely the technical aspects, 84.75% are in the good category in the cognitive aspect, 71.06% are in the quite good category. and in the social aspect, 86, 31% are in the very good category. Thus it can be concluded that students' technological literacy skills, especially in the cognitive aspects are still low and need to be improved so that in the future they can compete in technological development. Therefore, further researchers are advised to focus on cognitive aspects.
