Abstract

CV. Cita Nasional is a company engaged in processing pure milk into pasteurized fresh milk and homogenization. This research was conducted to analyze defective products using the Six Sigma, Poka -Yoke and Kaizen approaches. Defective products in cup packaging from July 2017 to July 2018 is 20.71% with a target of a maximum of 3% product defects. The purpose of the research is to find out the company’s process capability with DPMO and the level of sigma capability, analyze the factors that cause product disability along with proposed improvements. The method used with Poka-Yoke and determine the action plan in quality control efforts with the Kaizen approach. The result obtained based on the Six Sigma state, namely the Define stage, obtained quality characteristics or CTQ in the form of attribute data 7 characteristic of the causes of disability. The results of the company’s perpormance baseline measurement at the Measure stage of the company were in the condition of 3.383 sigma with DPMO 29.586. The analyze phase is made control map, pareto diagram and makes fish bone diagram to obtain the factors that cause disability. During the improve phase an action plan was developed using the Poka-Yoke approach. In the control phase continuous improvement is done with the Kaizen approach which includes the Five-M checklist concept, 5W+1H (What, Why, Where, When, Who, How) and the Five Step Plan.

Abstract

A study was carried out to assess the present status of blue swimmer crab (Portunus pelagicus) in Lancang Island, incorporating identification of fishing ground, also measurement of environmental condition and crab biometry. Monthly catch assessment was performed on JuneSeptember 2015 at three landing bases using structured questionnaire and morphometric sampling of minimum randomly selected 30 crabs. Bathymetric survey was conducted to produce depth-contoured maps combined with certain oceanographic parameters (sea surface temperature, salinity, water clarity, total suspended solids, dissolved oxygen, and nitrate-NO3) measured at 15 sampling sites. A grid map was produced to identify key areas of crab fishing grounds, recruitment habitat, and spawning habitats. During southeast monsoon, main fishing ground was distributed in the western and southern part of Lancang Island (grid C3, C4, and D5). In general, crab yields were dominated by female (66.9%) and 43.8% of them were bearing eggs. Four size classes were determined from frequency distribution of carapace width (Class 1 = 7.0-10.6 cm; Class 2 = 10.7-14.2 cm; Class 3 = 14.3-17.8 cm; and Class 4 = 17.9-21.5 cm), with Class 2 as the most prominent catch. Referring to ontogenetic migration trait of the species, presumed recruitment habitat for blue swimmer crab in Lancang Island is located at A6, where abundant juveniles were harvested in the area with strong oceanic influence and depth range of 24-30 m. Spatial coherence on the distribution of bearing egg female with several environmental parameters (sea surface temperature, salinity, and dissolved oxygen) indicates strong estuarine influence is required for crab spawning habitat at C3 and

Abstract

The self-combustion phenomenon that has the potential to cause fires in the coal mining industry in East Kalimantan is the subject of this study. The purpose of this study is to determine the quality and characteristics of coal that has the potential to trigger self-heating. In this research, 5 (five) samples of coal quality are analyzed from PT. Geoservice Samarinda using the proximate analysis method and analysis of calorific value and total sulfur. Next, determine ranking of coal and analyze the characteristics of coal samples that are prone to potential self-combustion. The results show that the five coal samples included in Sub-Bituminous rank with medium volatile matter considered to have sufficient potential to experience self-combustion. The most susceptible coal sample is sample code D1 because it also has lower inherent moisture and ash content and higher total sulfur content than other coal samples. However, further tests still need to be carried out to determine the percentage of total sulfur (pyrite) as a trigger for self-combustion. Environmental factor analysis is also required for validation.
