Judul: Morphometric Variation Of Genus Dobsonia (Mammalia, Pteropodidae) From Indonesian Papua
Abstrak: Based on 176 specimens and 32 characters of Dobsonia from Indonesian Papua, the study on their morphometric variation of Dobsonia were carried out. The specimens represented six OTUs, i.e G, B, R, E, SP1, and SP2. Univariate analysis computed all of adult specimens that consist of 171 external and wing characters and 176 skull and teeth characters on six OTUs. PCA and T test analysis computed to G, B, and R, whereas three OTU of them were projected in scatter plot. The results showed there are sexual dimorphism in D. minor and D. beauforti based on T test (p<0.05). The PCA was separated D. magna, D. minor, D. beauforti were significant on body, wing and teeth characters. D. emersa separated from other species on body and skull characters. SP1 and SP2, however, they can not be diagnosed separately from D. beauforti. The characters that can be used as taxonomical characters of Dobsonia are WT, HB and TV for body characters; FA, TIB, and DIG1P for wing characters; ONL, POW, PL, and MH for skull characters; I2M2, M2M2, WM1 and LM1 for teeth characters. D. minor that found at Waigeo island in 2007, formerly it found only in Papua mainland and Yapen Island.

Judul: A Monograph of the Genus Diplycosia (Ericaceae) in New Guinea
Abstrak: Diplycosia is an under-studied genus of Ericaceae, with a distribution confined almost to Malesia with most members are endemic to a single island or even a single mountain. New Guinea which, prior to this study, inhabited by 21 endemic species and once considered as one of the centres of diversity. Many species of Diplycosia in New Guinea are known only from limited collections: either only from the type specimens, or from only two or three specimens from a single or few locations; several have incomplete descriptions due to the absence of floral parts. Therefore, a taxonomic revision is needed for the genus Diplycosia in this island. Besides that, despite mostly being narrow endemic, 17 described species have not been evaluated for their IUCN conservation status which has become an obstacle for conservation actions. Therefore, an assessment is urgently required for the genus in New Guinea. A morphological species concept was used in this revision, and specimens were studied from various herbaria either directly or from digital resources: Australian National Herbarium (CANB), Harvard University (A), Muséum National d'Histoire Naturelle, Paris (P), Naturalis History Museum Firenze (FI), Naturalis Leiden (L), Papua New Guinea Forest Research Institute (LAE), PT Freeport Indonesia (tentatively as FRE), Research Center for Biology Indonesia Institute of Sciences (BO), Royal Botanic Gardens Kew (K), and Universitas Papua (MAN). Field explorations were carried out in Indonesian New Guinea, including Birds Head Peninsula and Mount Jaya area. An observation on qualitative anatomical characters of leaf epidermis was done in eight species. Assessment of conservation status was based on IUCN Red List guideline including range sizes calculated using GeoCAT using data sourced from herbarium specimens, literature and recently gathered data from the field exploration. A total number of 26 endemic species are accepted in New Guinea. Four new species are described namely Diplycosia elegans Mustaqim, Utteridge & Heatubun, D. hexamera Mustaqim, Utteridge & Heatubun, Diplycosia puradyatmikai Mustaqim, Utteridge & Heatubun, Diplycosia reticulifolia Mustaqim, Utteridge & Heatubun, together with a variety Diplycosia lorentzii var. acuminata Mustaqim, Utteridge & Heatubun. Diplycosia morobeensis var. ovatifolia Sleumer is reduced to a synonym of Diplycosia morobeensis Sleumer. Based on our current result, a higher number of species was reported from the western half of the island compared to the eastern half. So far, the central part of New Guinea from Jayawijaya Mountains east to the mountains near Indonesia and PNG border is an area with the highest diversity despite being poorly explored. The geographical range of the species varies from widespread species, found across the island, to very narrow endemics, some even restricted to a single mountain complex or a single locality. New Guinean Diplycosia grows as epiphytes or a terrestrial shrubs in mostly the mossy forests upwards to alpine vegetation. The elevation range from 800 in Wandammen Peninsula for D. kosteri and 4000 m in Mount Giluwe for D. rupicola and D. morobeensis. Seven species are known to inhabit alpine vegetation in New Guinea including the new species D. elegans. From this study, we recorded two new important information in the generic character of Diplycosia. It has been

Judul: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
