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%

Abstrak: Natural forest harvesting with Indonesian Selective Cutting and Planting (TPTI) can cause damage to the residual stand. Commercial species are important because they are used for production purposes. Damage to commercial types will reduce the number of trees which will harvested in the next cutting cycle. So far, research on damage to the residual stand with low intensity felling has not been widely studied. This study aims to calculate damage and the type of damage to commercial trees with diameter ≥ 10 cm due low-intensity felling. Measurement of the level damage poles and trees of commercial species are done on variable circular plots. The average area of the plot is 2.34 ha. The results showed that felling trees 0.43/ha can caused damages of 3 poles/ha and 3 trees/ha. Type of damage to the pole and tree was dominated by broken tree canopy

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.
