Judul: Identifikasi Kerusakan Komponen Chainsaw Serta Pengaruhnya Terhadap Produktivitas Penebangan Di PT Inhutani Ii Pulau Laut Kalimantan Selatan
Abstrak: Pengetahuan tentang pemakaian dan pemeliharaan chainsaw mutlak diperlukan bagi setiap operator. Penggunaan chainsaw yang tepat akan meningkatkan produktivitas dan penggunaan chainsaw yang tidak tepat akan menyebabkan kerugian berupa kecelakaan kerja, kerusakan alat serta penurunan produktivitas. Mengetahuai komponen-komponen chainsaw dan fungsi-fungsinya akan memudahkan operator dalam pemeliharaan chainsaw yang mereka miliki. Hasil analisis kerusakan komponen chainsaw menunjukkan bahwa komponen yang sering mengalami kerusakan adalah sprocket, busi, rantai, dan piston. Kerusakan dari komponen chainsaw dapat mempengaruhi besarnya waktu kerja tidak efektif sehingga akan membuat produktivitas yang dihasilkan menjadi kecil. Chainsaw merk Falcon tipe Pro 5800 memiliki produktivitas 2.45 m3/jam. Waktu efektif berkisar antara 0.2−0.4 jam dengan waktu rata-rata 0.3 jam dan waktu tidak efektif berkisar antara 0.18−0.24 jam dengan waktu rata-rata 0.21 jam.

Judul: Analisis Kerusakan Komponen dan Produktivitas Gergaji Rantai di Perum Perhutani Divisi Regional Jawa Timur KPH Madiun
Abstrak: The correct usage of chainsaw will increase the logging productivity. In the other hand, the incorrect usage will cause loss such as decline of the productivity, damage to the chainsaw and also causing occupational accident for the operator. The objectives of this research to find out the damage component, the cause of the damage component in chainsaw and also to find out the effect of the damage component towards logging productivity. The data was collected by analyzing the damage component, the cause of the damage chainsaw component and also by analyzing the effect of the damage component towards logging productivity. The analysis of the damage chainsaw component show that the most frequently damage component are chain, spark plug, piston and sprocket. The lack of understanding about the correct maintenance and treatment way for the tools and the usage of non-original part is one of the factors that cause the damage. The damage of chainsaw component can influence the non-effective work hours which result in the size of productivity.

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.
