Judul: Analisis keanekaragaman genetik durian lokal serang berdasarkan penanda morfologi, isozim, dan gabungan morfologi-isozim
Abstrak: Serang regency was known has high diversity of Durian (Durio zibethinus Murr.) landraces. In order to elucidate the genetics variability of the diversity, eighteen iandraces from four locations were subjected to morphological studies and isoenzymes analysis. The obtained data were ana:yzed for genetics relationshii) among landraces base on morphological and isoenzymes characters and compatibility between morphological and isoenzymes characters. Base on twelve morp:1ological characters there were 58 % of dissimilarity level indicates medium morphological variability. lsoenzymes analysis by using 7 proteins resulted 39 bands, and genetics variability of evaluated tree5 were 93 % of dissimilarity level. The concurrence analysis on morphological and isoenzymes analysis result, showed the very weak Rohlf correlation value (r=0,57). This result vVas indicated that grouping of durian landraces should be using joint of rnorphological-isozyme analysis. Joint morphological-isozyme cluster analysis showed that genetics variability among evaluated trees were 58 % of dissimilarity level, and at 51 % level dissimilarity, the durian landraces in Serang Regency should be r;lassified into four groups i.e., 1) Seureuh, Pedes, Sawah, Paok, (2) Balingbin\j, Emas, Puso, Tolaksana, Potret, Liter, Maslai, Onder, TM, (3) Belu, Carnal, and 4) Montong, Chanee, and Rampayak.

Judul: Analisis Keragaman Beberapa Genotipe Durian (Durio zibethinus Murr.) Menggunakan Penanda Morfologi dan Molekuler (ISSR).
Abstrak: Indonesia is one of the durian diversity center. Evaluation and characterization activities should be conducted to identify the genotipes in order to differentiate the individual plant in the spesies. Genetic variation of 21 collected genotipes of Indonesia Agency for Agricultural Research and Development (IAARD) Cipaku orchard, Bogor was evaluated using morphological and Inter Simple Sequence Repeat (ISSR) markers. Variability analysis based on 22 morphological characters gained 64 (100%) polymorphism. Molecular analysis using ten primers of ISSR amplified 48 locus. The 39 locus (81.25%) were polymorphic and the 9 locus (18.75%) were monomorphic, respectively. Both of the markers have different clustering, therefore they should be analysed using Joint Analysis. The result of the study showed genetic variability among 21 genotipes was grouped into 2 clusters on 0.51 similarity coefficient. The first group (A) consisted of the genotipe from Indonesia and the second group (B) consisted of Kanjau genotipe from Thailand with matrix correlation value was 0.83. Kanjau genotipe was suggested as a candidate in durian breeding programme, in order to increase Indonesian durian value in the future.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
