The research objective was to determine the effect of Trichoderma species and spraying frequency on the intensity of black pod disease (Phytophthora palmivora) and cocoa yield. This study was conducted in farmer's field in The East Aceh District, at June to Desember 2014. The choice of location was based on a history of the cocoa pod disease in the previous period or the location was endemic. The research was arranged in randomized block design non factorial, consisted of 10 treatments and 4 replications, i.e : A = control, B (T. harzianum + spraying frequency of 1 times), C (T. harzianum + spraying frequency of 2 times), D (T. harzianum + spraying frequency of 3 times), E (T. viren + spraying frequency of 1 times), F (T. viren + spraying frequency of 2 times), G (T. viren + spraying frequency of 3 times), H (T. asperellum + spraying frequency of 1 times), I (T. asperellum + spraying frequency of 2 times), J (T. asperellum + spraying frequency of 3 times). Each treatment consisted of 5 plants, the number of plant are 200 plants. At each plant is set 10 cacao pod as samples for observation of disease intensity. The results of the research showed that the the lowest intensity of black pod disease due to the combination treatment of Trichoderma species and spraying on 2 and 3 months after application frequency found in treatment D (T. harzianum + 3 times spraying frequency) was 12.50 % and 13.13 %. The highest cocoa fruit yield found in treatment D (T. harzianum + 3 times spraying frequency) was 45.75 kg and the lowest found in treatment A (without Trichoderma / control) was 27.02 kg.

The fossil energy reservation decreases day by day, this situation impacted to the energy crises especially fuel energy which is increasing in the price on over the world. The scientists/researchers are trying to develop the renewable energy (renewable fuel) as the energy alternative, one of these called biodiesel. Taking the benefit from Jatropha curcas’ seed as raw material for the fuel is one of the alternative ways to reduce the fuel demand and also can save the countries’ foreign exchange. J. curcas’ oil is renewable fuel and non edible oil, so that it will not compete with oil consumption, such as palm oil, corn oil, etc. The combination between Naphthalene acetic acid (NAA) (1- 2 ppm) and Benzyl Amino Purine (BAP) (0,5 and 1 ppm) for micro propagation of Castrol oil plant (Jatropha curcas L.) was tried to induce the callus formation by using the meristem shoot as the explants. The result showed that the combination of NAA 1.5 ppm and BAP 0,5 ppm gave the best result for the callus formation.

Telah dilakukan penelitian terhadap spektrum serapan cahaya pada sampel dye yang diekstrak dari daun suji (Pleomele angustifolia N.E. Brown), buah senduduk (Melastoma malabathricum L.) dan campuran keduanya. Tujuan dari penelitian ini adalah untuk mempelajari karakteristik serapan cahaya dan celah pita energi dari ketiga sampel. Pengujian dilakukan dengan peralatan UV-Vis untuk mengamati serapan cahaya dan celah pita energinya. Hasil penelitian menunjukkan bahwa nilai celah pita energi dari ketiga sampel berada dalam rentang cahaya tampak. Ekstrak daun suji dan buah senduduk memiliki lebar celah pita masing-masing sebesar 1,75 eV dan 2,12 eV. Ekstrak hasil pencampuran antara daun suji dan buah senduduk memiliki nilai lebar celah pita sebesar 2,06 eV. Ekstrak dye campuran memiliki nilai serapan cahaya dalam rentang 513,5 – 590,0 nm. Rentang ini lebih lebar dibandingkan dengan dye ekstrak daun suji dan buah senduduk yang masing- masing bernilai 672,5 – 705,0 nm dan 513,0 – 575,0 nm. Hal ini menunjukkan bahwa ketiga sampel dye berpotensi untuk diaplikasikan pada sel surya type DSSC (Dye Sensitized Solar Cell), dan semakin lebar rentang serapan cahaya, maka semakin besar pula peluang meningkatnya nilai efisiensi dari sel surya tersebut. The research about light absorption spectrum of dye sample extracted from suji leaves (Pleomele angustifolia N.E. Brown), senduduk fruit (Melastoma malabathricum L.) and mixture of both have been conducted. This research was aim to study the light absorption characteristic and gap energy of the three samples. UV-Vis instrumentation had used to visualize the light absorption and the gap energy. The result showed that the gap energy of the three samples is in the range of visible light. The suji leaves and senduduk fruits extract have gap energy about 1.75 and 2.12 eV, respectively. The mixture extract of both sample has gap energy about 2,06 eV. The mixture dye extract has light absorption range about 513.5 – 590,0 nm, wider than suji leaves and Senduduk fruits dye extract that have light absorption range about 672.5 – 705,0 nm and 513,0 – 575,0 nm, respectively. It is mean that the three samples have the potential to be applied for the Dye Sensitized Solar Cell (DSSC), and the wider light absorption range the higher efficiency of sun light convert to energy.

Heavy metal contaminants like mercury is a serious problem to human, animals, and some plants’ health. Phytoremediation is an alternative technique, which can remediate the contaminants from soil using a hyperaccumulator plant. The goal of this research was to study anatomical changes of plant main organs (roots, stems, and leaves) of Ipomoea reptans which are assumed as a hyperaccumulator plant that grows in mercury contaminant. The mercury concentration of the growth medium was 0, 61.871, 92.258, and 107.046 ppb. Ipomoea reptans were harvested after 27 days. The anatomical changes of the plant’s main organs were observed by preparing the cross-section of roots, stems, and leaves of I. reptans. The result showed that mercury treatment has caused anatomical damage at the xylem vessel of the root, and decreased bulliform cell size. The anatomical damage was found only in the root of I. reptans. The mercury concentration in media decrease to 0 ppb (P0), 50,420 ppb (P1), 58,583 (P2), and 96,120 (P3).
