Judul: Keanekaragaman Ordo Hymenoptera di Perkebunan Kelapa Sawit, Perkebunan Karet dan Hutan Karet di Jambi
Abstrak: There were much deforestations from primary forest to rubber and oil palm plantation in Jambi. Some taxa could be bioindicator, for example is Hymenopteran insects. This research purposed to study the diversity of Hymenoptera in oil palm plantation, rubber plantation and jungle rubber in Jambi. Insect collected by using insect net at 7 to 11 am. The environment parameters measured were temperature, humidity, and light intensity. In three vegetation habitats and villages adjacent Hutan Harapan, Jambi were found six families of Hymenoptera, i.e. Apidae, Halictidae, Megachilidae, Pompilidae, Sphecidae and Vespidae. Highest abundant found were Apis and Trigona. Endemic species found was Trigona minangkabau. The highest diversity of Hymenoptera was found in oil palm plantation (16 species), and the less diversity was in rubber plantation and village (9 species). Generally, number of species of Hymenoptera didn’t correlated significantly with temperature, light intensity and humidity.

Abstrak: Oil palm and rubber are potential commodities for international trade and source of income for Indonesia. In the field, these commodities frequently attacked by termites. The diversity of termite species in those two plantation can be influenced by many factors. The aim of this research was to asses the diversity of termites species in oil palm and rubber plantations and factor affecting. Research was conducted on 4 plots (50 m x 50 m) on each plantation in Kabupaten Sarolangun, Jambi. Transects (50 m x 10 m) were set in the midlle of the plots and termite found were collected and identified. In addition, wooden stakes made of rubber wood were driven into the ground inside the subplots and termites attacked those wooden stakes were also collected. The result showed that diversity index were higher on rubber plantation than oil palm. Canopy coverage and type of vegetation affect the diversity of termite. Termite species found on oil palm were to 9 species: C. mohri, M. gilvus, M. insperatus, N. longinasoides, N. proatripennis, P. setiger, S. javanicus, S. medioobscurus and T. propinquus. Meanwhile termite species found on rubber plantation were 12 species: B. flavicans, C. mohri, H. hospitalis, M. insperatus, N. proatripennis, N. javanicus, P. aequalis, P. setiger, S. longirostris, S. medioobscurus, S. tarakensis and T. propinquus

Abstrak: Dengan metode casting dan perlakuan annealing, dapat dibuat lapisan nanokristal semikonduktor TiO, pada substrat Transparant Conductive Oxide (TCO). Penambahan dye Methylviolet Thiocianate (MVSCN) dan lapisan CuSCN pada TiO, tersebut menghasilkan sel surya n-TiO,ldye/p-CuSCN yang dapat menyerap foton dan mengubahnya menjadi energi listrik.
