Abstract

To overcome quality problems regarding product defects that occur in the company, it is necessary to do an analysis related to the problems that occur and it is necessary to plan improvements to reduce consumer returns. This study aims to analyze and plan improvement plans using the Quality Control Circle (QCC) method using Seven Tools. The Seven Tools used consist of a check sheet, run chart, histogram, scatter diagram, Pareto diagram, cause and effect diagram (fishbone diagram), and control chart. The research was conducted using the interview method with the parties involved with the object and problem. The research data taken is the company's historical data in 2020. The results show that product defects can be caused by various factors such as humans, machines, climate or weather and storage methods. The criteria for defects that often occur in the company are damaged products due to fractures, rusty products, and product sizes that do not match. It can be seen from the criteria for these defects, improvements that can be made are by providing suggestions to overcome the problem so as to reduce the returns that occur in the company.

Abstract

The small crab animal is important for the fisheries sector in Indonesia, but usually the small crab industry only takes meat and allows the crab shell to become a pile of waste.  To reduce the potential for pollution caused by a small crab shell waste, the waste can be reused to obtain chitin.  Small crab shell waste still contains quite a lot of chemical compounds, including protein, minerals (CACO), and chitin.  The study conducted chitin extraction with a process preceded by deproteination and then demineralization.  Chitin was characterized using Fourier Transform Infra Red (FTIR) and Scanning Electron Microscopy (SEM).  The results showed that chitin was successfully extracted from the small crab shell through the deproteination and demineralization process with FTIR l, which results the characteristic spectrum of chitin compounds such as waves of 3433 cm 'for -OH, -NH groups.  The absorption around the wave number 3433 cm occurs because of the overlap between the absorption -NH and -OH and the wave number 701 cm 'for the b-1,4-glycosidic group.

Abstract

Fischer-Tropsch (FT) Synthesis has been widely known for centuries as the process of converting syngas to liquid fuels. Several reactors including Slurry bubble column, fluidized-bed, and fixed bed reactors have been used for FTS on an industrial scale. Although science has seen remarkable development in technology for FT synthesis, the industry still faces challenges in optimizations of process parameters and achieved desired selectivity.  Extensive research has been continuously conducted to seek the best FT reactor offering heat uniformity and efficient heat transfer across the reactor to increase the catalytic activity and its lifetime. Dielectric Barrier Discharge (DBD) plasma has become one of the options to deal with these issues. This reactor work under low temperature delivers a synergistic effect between plasma and catalyst to break H2 and CO bond. DBD plasma is also suitable for feedstock with high H2/CO molar ratios. It is also found that FT catalyst such as cobalt catalyst used in DBD plasma was well dispersed on the support which in turn favour the selectivity toward liquid hydrocarbon.

Abstract

Microalgae are photosynthetic microorganisms with varying cell morphology, both unicellular and multicellular (forming small colonies). This research is about CO2 for the growth of green microalgae by cultivating algal strains in tank type reactors or fermenters. The study included optimization of the productivity of green algae in the capture of CO2 which can be used as a greenhouse gas catcher. Green algae were isolated from several waters in Banda Aceh. These microalgae species are isolated and have been identified, then cultivated in irradiated tank containers with 4 fluorescent lamps (2x8 watts; 4x8 watts) installed on the outside of the tank. This study evaluated the comparison of the growth of aerated microalgae O2 (1.25 liters / minute) with fixation of CO2 (1 and 2 liters / minute). Catching CO2 into carbon dioxide by looking at growing biomass, and the yield content of oil in biomass. The results showed that there were significant differences in the growth patterns of microalgae given O2 aeration and CO2 fixation. Modified CHU 13 Detmer Modified media did not provide a significant difference to algal growth. With a large intensity of light with a medium that is sufficient to increase the growth of microalgae until it reaches the death phase.
