The aims of the research are to study and analyze the effects of TQM on the Competitive Advantage and Firm Performance as well as the effects of SCM on the Competitive Advantage and Firm Performance in PT Semen Tonasa, a cement company in Pangkep, South Sulawesi, Indonesia. There were ten (10) indicators of TQM variables, six (6) indicators of SCM variables, five (5) indicators of competitive advantage variables, and four (4) indicators of firm performance variables using a balanced score card. Data collections were conducted using a questionnaire method. The respondents for the research were all middle managers in all units in PT Semen Tonasa. There were 122 respondents. Structural Equation Modeling (SEM) was used to analyze the hypothesis. The results of the research showed that there were positive and significant effects of the Total Quality Management (TQM) on the competitive advantage, the Total Quality Management (TQM) on the firm performance, the Supply Chain Management (SCM) on the competitive advantage and the competitive advantage on the firm performance. It was found that there were indirect effects of the TQM and SCM on the firm performance through the competitive advantage.

(KUB - IK ) Mataram  Macoa is a cocoa industry . The cocoa industry can produce chocolate with a cocoa material capacity of 87 kg per month or 1.0444 tons per year. Based on data from the Polewali Mandar Regency Statistics Agency, in 2018 the chocolate industry has a prospect that is still less proven with the data from BPS Polewali Mandar Regency, there is only 1 group of cocoa industry centers and the number of business units is 1 unit (BPS Polewali Mandar Regency, 2018).The company does not currently have a structured risk management to identify and mitigate risks that occur, especially in the supply chain function. By using the House of Risk method, the risks that may arise and their causes can be identified to simultaneously find ways to mitigate these risks to improve the operational quality of the Kelompok Usaha Bersama Industri Kecil Mataram Macoa  and open opportunities to detect profitable business opportunities for the company. The purpose of this paper is to determine the causes of the dominant risk and design response measures in the Kelompok Usaha Bersama Industri Kecil Mataram  Macoa. The basic method of writing is descriptive method and is implemented by using a case study method through a quantitative approach. The selection of respondents was carried out using purposive sampling technique. Methods of data collection by observation, in-depth interviews, questionnaires and literature study. The results of this paper indicate that in the activity plan there are 2 risks, in source activity there are 5 risks, in make activities there are 5 risks, in delievery activities there are 3 risks, and in return activities there is 1 risk. The risk treatment plan is designed to reduce the risk status for each risk event using a risk matrix

Determining the optimal number of employees in a company is a basic condition that must be concern into account when drafting a work plan. The work design process ultimately aims for balance the physical and mental aspects of humans in completing certain tasks so that. Determination of the number of employees whit the existing workload will support employees performance in perform their duties optimally. The purpose of this research is to determine the optimal number of salesman based on the workload calculated using the Full Time Equivlent method. Based on the results of research at PT. Xyz used the method FTE is know that the workload of the 4 salesman is classified as overloaded. Where is sales I has a workload of 1.48, sales II has a workload of 1.70, sales III has a workload of 1.66, sales IV get a workload of 1.42. Based on the table of labor requirements to the FTE value, the number of initial salesman was 4 sales and the addition of the number of salesman is as many as 10 salesmen. So, the optimal number of salesmen in Makassar city is 14 salesmen.

The purpose of this research are to study the temperature influence in hydrocracking process of the nyamplung oil (Calophyllum inophyllum) using a non-sulfided CoMo/γ-Al2O3 catalyst and to develop a simple kinetic model in interpreting the data of hydrocracking products. The experiment was carried out in a pressurized batch reactor operated pressure up 30 bar. The CoMo catalyst supported with γ-Al2O3 was prepared through impregnation method without sulfidation process. The operating temperature varied from 200 to 350 o C. The results show that the non-sulfided CoMo/γ-Al2O3 catalysts, nyamplung oil triglycerides can converted into gasoil and gasoline-like hydrocarbons. The triglyceride hydrocracking reaction of nyamplung oil followed a several stages, i.e., hydrogenation, dehydrogenation, and cracking. Based on the compounds contained in liquid product, hydrocracking reaction was dominated by decarboxylation. The products obtained in hydrocracking process of nyamplung oil are classified to gasoil (C11-C18) and gasoline (C5-C10). The triglycerides hydrocracking reaction of nyamplung oil was assumed by following a series reaction mechanism and a simple kinetic model used for determined the kinetics constants. The highest reaction conversion is 99.10% obtained at temperature of 350 °C for 160 minutes reaction time.

PT Japfa Comfeed Indonesia Tbk is one of the largest and most integrated agri-food companies in Indonesia. The company's main business units are the manufacture of animal feed, chicken breeding, poultry processing, and agricultural cultivation. This company will automatically continue to increase its production results both in terms of quantity and in terms of quality to be able to compete in the market so that it can expand market share and offer products at affordable costs for consumers. At present, business progress is strongly influenced by fluctuations and variations in consumer demand. This also has an impact on the production of chicken feed carried out by PT Japfa Comfeed Indonesia Tbk Makassar unit. With the increasing demand for chicken feed, an effort is needed so that the production process runs according to available and profitable resources. This research aims to determine the optimal amount of production to generate optimal company profits. The method used in this study is the goal programming method because it can solve problems optimally with more than one goal. The results of this research show that the product of goal programming optimization is more profitable than the companies. The results obtained from this research are the optimal number of products is 4,967,155 kg, and the minimum production cost is Rp. 1,382,685,942,075, and the sales profit is Rp. 314,569,267,925 for a period of one year.
