Judul: Kerusakan Tingkat Tiang dan Pohon Jenis Non Komersial Akibat Penebangan Intensitas Rendah di PT Inhutani II Malinau
Abstrak: Felling will cause residual stand damage to commersial and non commersial species. Commersial species keep the stability of forest biodiversity. The purpose of this study was to measure the damage of non commercial poles and trees and identify type of stand damages. The plot was circle with radius two times of the total height of central tree. Felling intensity in this study was 0.43 trees ha-1. This study showed that the damage due to low felling intensity to the pole and tree was 3.9% and 2.6% respectively. The type of pole damage was crown injury (27.2%), broken trunk (25.8%), leaning (15.9%), uprooted (14.6%), bark and wood injury (10.6%), and buttress and root injury (6%). The type of tree damage was broken crown by 37.3%, broken trunk 24.0%, uprooted 18.7%, bark and wood injury 14.7%, buttres and root injury 2.7%, and leaning 2.7%

Judul: Pengukuran Kerusakan Tegakan Tinggal Akibat Penebangan Intensitas Rendah Menggunakan Dua Bentuk dan Ukuran Plot yang Berbeda
Abstrak: Measurement of residual stand damage aims to know the structure and composition of natural forest stands due to logging. The objective of this study are to measure the degree of residual stand damages use fixed square and circular dynamic plot, indentify type of residual stand damage, measuring of opened areas and length impact caused by felling. This study showed that the degree of residual stand damage in fixed square plot, respectively, for seedlings and saplings 3.66%, for poles 5.52% and 4.26% for trees. Meanwhile, the degree of residual stand damage in dynamic circular plot, respectively, for seedlings and saplings 2.33%, 4.21% for poles, and 2.86% for trees. Circular plot results more accurate data because it has standard error and ceofficient of variance smaller than square plot. All types of damage occurred in both plot. Greatest type of damage is crowns broken and smallest type is buttress and roots broken. The degree of opened areas caused by felling, respectively, square plot is 365.69 m2/ha, and 523.09 m2/plot for circular plot. Base on this study, length impact caused by felling is 69.24 m or 1.63 total height of tree felled.

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.
