Abstract

A production process will not be free of difficulties with faulty goods during its implementation; this is a problem that is a major factor in the production process; if the process still has many problems with product defects, the process has not been adequately regulated. Moving on from the issues raised above, the author did research at UD. Meurah Mulia, a paving stone manufacturer. For the time being, the control process in the manufacturing process is inspection control, which is an inspection that just distinguishes good and faulty goods without improving the process. In this scenario, the authors advise using the Six Sigma approach to eliminate flaws, which is a process control method that can affect decisions connected to product manufacturing, namely the production and insfection functions. The results of the analysis through processing with the Six Sigma method, which goes through five stages, namely define, measure, analyze, improve, and control, show that the current control process is ineffective, as evidenced by the occurrence of numerous defects in the manufacturing of Paving Blocks.

Penentuan sampel ditentukan dengan teknik non probability sampling yaitu sampling purposive sebanyak 100 sampel. Metode analisis yang digunakan yaitu Partial Least Square (PLS). Dengan menggunakan software SmartPLS versi 3.2.6 dan SPSS versi 17.0. Hasil penelitian ini menunjukkan bahwa kepuasan pelanggan pada PT. XYZ Banda Aceh dapat diukur dari 5 dimensi kualitas pelayanan yang terdiri dari tangible, emphaty, reabilty, responsiviness dan assurance.

Abstract

This research aimed to determine the optimum coagulant that can be used to purify PDAM Tirta Meulaboh water which often has a cloudy color during the rainy season. The coagulants used are PAC and Tawas with the chemical formula Al2(SO4)3 and Poly Aluminum Chloride is known as PAC with the chemical formula Aln(OH)mCl(3n-m). The test was carried out by mixing 10 grams of alum and PAC which were dissolved in 1000 mL of water/aquades each. The treatment was carried out by dissolving each 1 mL in 1000 mL of PDAM water sample equal to 10 ppm. Variations in the addition of PAC/alum to each container were 10, 20, 30, 40, 50 and 60 ppm. Furthermore, rapid mixing was carried out at a speed of 100-150 rpm and slow at 20 rpm. The results showed that 10 ppm of PAC added to the sample produced turbidity of 5.2 NTU and pH 7.8, 20 ppm: 4.1 NTU and pH 7.5, 30 ppm: 3.8 NTU pH 7.3, 40 ppm : 2.3 NTU pH 7.2, 50 ppm: 1.5 NTU pH 7.1, 60 ppm: 0.8 NTU and pH 7.0. Samples added with 10 ppm of alum produced turbidity of 5.5 and pH 6.8, 20 ppm: 5.1 pH 6.7, 30 ppm: 4.5 pH 6.6, 40 ppm: 3.2 pH 6.6 , 50 ppm: 4.3 pH 6.4 and 60 ppm: 5.0 pH 6.3. The conclusions from this study indicate that PAC and alum coagulants can affect turbidity and pH levels of water, the optimal addition of PAC coagulant to purify water is 20 ppm, while the optimal addition of alum coagulant to purify water is 30 ppm.

Abstract

The West Aceh Regency Library and Archives Service is an agency engaged in carrying out general government tasks, building libraries, and providing services openly to its users regardless of age, education, and social status factors in society. However, there are still some problems that make visitors unsatisfied, including incomplete and non-specific book collection facilities, lack of the latest published books, placement of books on shelves that do not match the location, and inadequate facilities in the reading room. This study aims to determine and categorize the attributes that are considered important from the desire of visitors to know the quality of services provided by the West Aceh District Library and Archives Service using the canoe method. The Kano method is one of the simple methods that can improve products and services to customers. This method is a model that classifies attributes and is analyzed based on customer perceptions, and the effect on customer satisfaction. The results of calculating the average value of service quality in all dimensions of the canoe method show that visitors are not satisfied enough and there are still deficiencies in service quality at the West Aceh Regency Library and Archives Service. Of the 22 attributes, some attributes need to be improved, namely one-dimensional category attributes 5,8,9,11,14,16, and 19, indifferent category attributes 10,13,15,17,18,20,21 and 22, attributes The ones that are maintained are the attractive 12 categories and the attributes that need to be improved are the must-be categories 1,2,3,4,6, and 7 which illustrate that the more an attribute does not function properly, the visitor satisfaction will decrease.
