The problem of household waste, which accounts for 50-70% of the total waste in Indonesia, mainly in the form of organic waste such as food and vegetable scraps, is a major challenge in environmental management. Composting is an effective method of managing organic waste by turning it into compost. However, organic waste management in Indonesia is still minimally practiced because it is considered to have no economic value. A 50 kg capacity composter machine equipped with a vertical mixer and using an electric motor can increase composting efficiency. This study aims to analyze the feasibility of composter machines and to analyze the effect of speed and mixing time on composter machines on the homogeneity of organic waste. The research method used is quantitative experimental with factorial experimental design (DOE) to analyze the effect of speed and stirring time on the composter machine on the homogeneity of organic waste. The stirring speed variations tested were 30, 45, and 60 RPM, with mixing times of 20, 30, and 40 minutes. The results showed that the single mixer composter machine proved to be feasible and reliable in producing homogeneous organic waste, with a high process capability value of 5.86. The use of mixing speed from 30 RPM to 60 RPM and mixing time from 20 minutes to 40 minutes significantly increased the homogeneity of organic waste, with the highest value of 97.54% at 60 RPM speed for 40 minutes.  

Quality Management has been known since four thousand years ago, when the ancient Egyptians measured the dimensions of the stones used to build the pyramids. In modern times, quality management activities have developed through several activities, namely inspection, quality control, quality assurance, quality management and integrated quality management. The problem currently occurring at Bir Pletok Bang Udin UMKM in quality management is that they do not know the right composition to increase quality and do not know the standard level of factors used, so the author has carried out quality improvements in product manufacture. This research uses the DMAIC cycle (Define, Measure, Analyze, Improve and Control) with the Taguchi method for quality improvement. The aim of this research is to combine the DMAIC cycle with the Taguchi method to improve the taste quality of beer pletok drinks. The results of this research are that there is a significant change in the DPMO value and sigma value, before the DPMO improvement was 614.092 and the sigma value was 1.21, this value was relatively low, after the improvement the DPMO value became 32, this proves that the number of defects has decreased and the sigma value has increased to 5.50 This proves that there has been a large increase in process capability, so that the improve phase has proven to be very effective in improving quality and process capability.

The information systems currently used by PT Media Print need to be evaluated to ensure that they remain relevant, efficient and secure. In the competitive print media industry, it is important for companies to ensure that their information systems support business processes well and provide high-quality service to customers. This audit aims to ensure that the information system functions properly, protects sensitive information, and meets organizational goals. By using an information system audit, it is hoped that it can help identify areas where improvements or improvements are needed to improve service quality and control existing security in information systems, including access management, data encryption, user activity monitoring, and data protection measures. From the research carried out, the final result was obtained, namely DSS03 (Manage Service Requests and Incidents) showing the overall level of capability in the DSS03 sub-process and the average results for the DSS03 IT Process itself are shown in table 3 process capability domain DSS03 manage operations.

An audit needs to be carried out so that an information system is able to meet IT Governance requirements. PT. Jaya Karya is a company operating in the field of goods delivery services that has used information systems to support its business processes for the last 4 years. It is time now to carry out an audit of the goods delivery information system  This is so that we can find out whether the information system implemented is in accordance with the vision, mission and goals of the organization as well as testing the performance of the information system. In this research, an analysis of the goods delivery information system at PT. Jasa Karya Palembang branch uses the COBIT 5.0 framework with sub domain MEA01 (Monitor, Evaluate, and Assess Performance and Conformance) with process capability level calculations and also analysis of Strength, Weakness, Opportunity and Threats (SWOT), Internal Factor Analysis Summary (IFAS) , as well as External Factor Analysis Summary (EFAS)). Data was obtained through observation techniques, interviews, literature study. Respondents for the data consisted of Branch Heads, Operations Managers and Operational Staff.

To win competition in business world, all businessman must have selling method effective efficiently in order to get right target and low east, to reach the target, the company should have same index parameter. To measure quality of service that be given to customer, many company try to implement service excellence, but fail, meanwhile the company is given out cost, time, power no so a little to do some training for his employees, what problem ?, actually, just giving training is not one solution because, familiarization, and manner to save customer is not so enough will be paradigm and skill for front line to save the customer, but seriously, high commitment at each of organization especially top management service excellence must be implemented in structural oriented at each of company.
