Judul: Evaluasi Faktor-faktor yang Memengaruhi Berat Tebu per Hektar Menggunakan Korelasi Genetik dan Analisis Jalur.
Abstrak: Sebagai komoditas utama sumber bahan pemanis, pemuliaan tebu dilakukan untuk memperoleh hasil produksi yang optimal yang ditandai dengan besarnya hasil berat tebu per hektar. Penelitian ini bertujuan untuk menentukan faktor-faktor agronomi yang memengaruhi berat tebu per hektar menggunakan korelasi genetik dan analisis jalur. Selain itu, penelitian ini juga bertujuan untuk menduga nilai heritabilitas karakter-karakter agronomi sebagai dasar penentuan karakter dengan daya waris tinggi. Penelitian ini menggunakan data hasil percobaan multilokasi tanaman tebu Balai Tanaman Pemanis dan Serat (Balittas) dengan rancangan acak kelompok lengkap (RAKL) dengan faktor klon dan kondisi lahan. Klon dan kelompok diasumsikan sebagai faktor acak sedangkan kondisi lahan atau lokasi diasumsikan tetap. Hasil penelitian menunjukkan bahwa karakter jumlah ruas, lebar daun, panjang daun, tinggi batang, dan berat tebu per hektar mempunyai keragaman genetik yang tinggi. Berat tebu per hektar mempunyai korelasi genetik yang tinggi dengan tinggi batang, berat tajuk, dan diameter. Berdasarkan analisis jalur, karakter tinggi batang, diameter, berat tajuk, panjang ruas, dan lebar daun dapat dijadikan kandidat acuan dalam proses seleksi klon tebu guna mendapatkan berat tebu perhektar yang tinggi. Berdasarkan hasil nilai heritabilitas, tinggi batang merupakan satu-satunya karakter yang akan digunakan sebagai acuan karena mempunyai kemampuan yang tinggi untuk mewariskan sifat kepada keturunannya.

Abstrak: The aims of this experiment are to study the geneUc variation, heritability of the wlleat germplesm collection and cotrelation among chafllctelS using pathcoefficient analysis. This experiment was conducted at Rice Research Station in Kuningan, West Java on June until October 2002 using RandOmized Completely Block Design (RCBD) with three replications. each of the twenty-seven genotypes of wheat was planted on four rows with 3 m lenght. The interrow and interplant spacing were 25 em and 10 em, respectivity. Deta obtained from the twenty-seven genotypes were subjected to variance analysis and the heritability of the traits _mated by component of variance method. Correlation coefflcients were computed according to the formula of Goulden (1959). Direct and indirect path coefflcients were calculated as described by Dewey and Lu (1959). High geneUc varianon displayed by l00-grain weight, numberofUllelS per plant and number of spikes per plant The esUmation of heritability ranged from 0 to 94.58%. The days to nower, plant height, spike length, number of greins per spike, and l00-grain weight were uncotrelated with grain yield per plant. In the other hand, the days to harvest, number of tillelS per plant, number of Spikes per plant, dry spikes weight, and harvest spikes weight were positively and significanty correlated with grain yield per plant. The number of graints per plant, number of spikes per plant, number of grains per spike, and l00-grein weight each had a posiwe direct effect on grain yield per plant. The indireci effect on grain yield per plant via number of tillers and number of Spikes (productive tillers ) per plant showed by days to harvest, dry Spikes weight, and harvest Spikes weight. The number of productive tillers per plant was a good criteria to be used towards improvement of grain yield.

Judul: Synthesis of Molybdenum Trioxide (MoO3) by Electrochemical Method for Electrochromics Application
Abstrak: Molybdenum trioxide (MoO3) thin films have been deposited on glass substrates by electrochemical method using ammonium heptamolybdate tetrahydrate ((NH4)6Mo7O244H2O). The films were deposited onto glass substrates as the control temperature at 25○C and annealing treatment at 350○C for 30 mins. The MoO3 thin films were investigated by UV-Vis, X-ray diffraction techniques (XRD), Scanning Electron Microscopy (SEM). The JCPDS card show that orthorhombic MoO3 (α- phase) has been formed. Molybdenum trioxide MoO3 formation was also confirmed by JCPDS card no. 35-0609. The SEM photographs revealed that the spherical and rod-like morphology and their grains size increased with increasing of heating temperatures. The measurement results show that the MoO3 thin film prepared at 350°C transmited about 80% of the visible spectrum. The effect of different heat treatments on surface morphology, thickness and optical properties of the films are discussed in this thesis.
