“…The high value of BD in the patchouli-developed soil can be reduced by adding organic amendments such as compost, green manure, biochar, or manure. Organic matter has a light-specific gravity so that in the soil it can play a role in reducing the value of bulk density [15] [16]. In Figure 2, it can be seen that the highest soil porosity value of 50.77% is found in ab1 soil samples that are imultiple cropping managed in Woyla Induk District and in AB15 soil samples on hilly land in Sungai Mas District, while the lowest porosity (48.46%) is found in AB2 soil samples, which are also found in Woyla Induk District.…”

Good soil physical characteristics are of great importance to the growth of patchouli plants. This study aims to examine soil conditions analyzed by soil physics in patchouli development areas in Aceh Barat Regency because it is one of the patchouli development areas in Aceh Province. The research method used is a descriptive method, namely through field surveys and laboratory analysis. In this study, we focused on two physical characteristics of soil, namely bulk density (BD) and soil porosity. Soil samples were taken purposively at 15 patchouli planting sites in three sub-districts in Aceh Barat, namely of Woyla Barat, Woyla Induk, and Sungai Mas, each representing a monoculture, multiple cropping and mixed garden system. Each site was given five points of soil samples at a depth of 0–30 cm using sample rings. The results of the analysis showed that, in general, the bulk density (BD) of the soil is included in the weight category with BD values ranging from 1.27–1.30 Mg/m3, while the porosity of the soil is classified as rather poor to rather good with values ranging from 48.46–50.77%. From the analysis of the data obtained, it shows that the entire patchouli development area in West Aceh has relatively homogeneous soil physics characteristics from the aspect of soil physics and soil constraints are found in poor conditions. Therefore, to improve soil quality, it is necessary to add ameliorant materials, especially types of organic amendments such as compost, biochar, manure, and other supporting factors.

“…When the class number is less than 2,the measurement system is no value for the control process, because it is unable to distinguish the parts; when the number of class is 2,the data can be divided into 2 groups, such as high and low; when the number is 3,the data can be divided into 3 groups, like high, middle and low;5 or higher numbers shows the measurement system can be acceptable [10]. The results show that the data is normally distributed, and the Cpk = -0.51.The benchmark value is 1.33, so the process capability of M needs to be improved.…”

Abstract.With the development of science as well as technology and the influx of shoemaking companies abroad, our traditional shoemaking enterprises face greater pressure to survive, and product quality problems are in urgent need of improvement. Aiming at the quality problems of M shoemaking enterprise, DMAIC method is used to conduct the product quality improvement, and a mathematical statistics software Minitab is used to analyze the data. Moreover, the optimum combination of the key influencing factors is determined by orthogonal experiment design as well as a set of specific quality improvement plans are put forward. Finally, the production process capability of M enterprise is improved, the product bonding strength is enhanced, customer satisfaction is improved, and the thoughts of product quality improvement and reference are provided for domestic traditional shoemaking enterprises.
