This research had a main purpose for studying the utilization of water hyacinth as the key component of paper production mixed with the agricultural waste as pineapple leaves and leaf sheath of banana tree. The paper pulps were prepared from 5 g/l NaOH at 90-95oC for 3 hours then bleaching with 5 g/l Hydrogen peroxide at 90-95oC for 30 minutes. The whole pulps were detached improvement with 5g/l Acramine 3187 before paper establishment production. Finally the strength of obtaining papers was consideration and competition to any craft paper type. As the results the appropriate ratio of paper was 70% water hyacinth (stem) 10% pineapple leaves and 20% leaf sheath of banana tree. It had 31.19 kN/m2 for bursting strength tearing strength as 309.17 mN and 0.49 mm thickness. The basis weight was 183±5 g/m2. The achieved paper was equivalent as KI craft paper. It was presented for packaging boxes and other procedures.

This study aims to examine directions for addressing student quarrel problems in a private vocational college and to propose the possible directions in preventing and solving those problems.

The purpose of this research is to study productivity improvement at electronic parts’s assembly line finding the work stations with work station time longer than takt time. This research applied the 5W1H technique as a tool to problem analysis fundamental of hand motions to improve productivity. The study found that the assembly line consisted 15 work stations and a cycle time of 12.0 seconds which greater than the takt time which was 10.5 seconds. The work station time no.6 took longer than the takt time. The fundamental of hand motion technique was applied. By separating or eliminating the fundamental of hand motion did not affect the performance of the work stations. By being integrated the fundamental of hand motion with previous work station or next work station. As a result of research is the new cycle time of this production line is 10.0 seconds the production line capacity increased from 300 pieces per hour to 360 pieces per hour 20 percent increase
