The findings of the analysis of the 2023 safety rating globally from countries in Asia, it is known that the Indonesian region has the lowest safety rating of various aircraft industries. This research aims to analyse the safety rating in the aircraft industry to support the business process in the operational process with the Total Quality Management (TQM) method, and measure the safety rating. Continuous improvement of TQM on business process with the result of Cluster Technical Record justification has its own hierarchy, which focuses on maintenance status and record component to improve aircraft safety rating. The results of measuring the safety rating of aircraft in 2023 registration PK-LAO with the highest safety rating of 96.6% and PK-LAZ with the lowest safety rating of 92.3%. The most dominant cause in PK-LAZ registration is known to be the six most dominant factors, namely hardcopy and system status open, overload work, late validation, analysis time, system error, scanning only one. Continuous system improvement is the implementation of TQM elements in making periodic improvements to support the achievement of quality and risk management. This recommendation can help the implementation and improvement process so that it can be used as a safety rating evaluation material in the aircraft industry.

The rapidly increasing quantities of waste generated, especially in urban areas such as Jakarta, ... more The rapidly increasing quantities of waste generated, especially in urban areas such as Jakarta, becomes a major concern of various stakeholder. With the average of waste per person per day by 1 kg, it is estimated that Jakarta produces 7,000 ton tons of urban waste per day in 2017. The dominant type of urban waste in Jakarta after organic waste is paper waste (18.4%) and plastic waste (13.2%). Present disposal and processing capacity is probably not sufficient to deal with the expected growth. The community's active role in dealing with municipal solid waste issues through the concept of 3R (reduce, reuse, recycle) will reduce the burden of waste that must be transported to the landfill. In South Meruya Village, West Jakarta, two groups of PKK (empowerment of family welfare) Women, which are processing urban wastes from plastic solid waste and paper waste. Unfortunately, PKK South Meruya womens have never attended business development training, product quality is also less co...

The waste is simply dumped into the surrounding water bodies. Raw wastewater quality characteristics of batik small and medium enterprises (SMEs) included pH (6.05), turbidity (1306 NTU/Nephelometric Turbidity Unit), TSS/Total Suspended Solid (1248 mg/l) and COD/Chemical Oxygen Demand (3712.5 mg/l). M. oleifera seed powder coagulant addition and deposition length as well as their interactions in batik effluent treatment significantly (0.01) affected turbidity decrease. Interaction of M. oleifera seed powder coagulant addition (4000 mg/l) and deposition length (180 minutes) showed the lowest turbidity decline namely 59.25 NTU (95.5% reduction). M. oleifera seed powder coagulant addition significantly (0.01) affected TSS reduction. Deposition length and the interaction between the coagulant addition and deposition length did not significantly affect the TSS. Treatment of 5000 mg/l M. oleifera seed coagulant and 60 minutes precipitation gave the best results with the lowest TSS of 156.00 mg/l (87.5% reduction). In general, the best treatment combination was shown by treatment of 5000 mg/l coagulant addition and 180 minutes long deposition which eventually produced turbidity of 61 NTU and TSS of 170 mg/l. However further investigation need to be carried out to treat the remaining high COD.

Today palm oil based industries are facing global challenges related to environmental issues. To against these challenges, it is necessary to have an environmentally friendly supply chain. However, the limited resource owned by the company requires the integrated environmental strategy with the company's business strategy. The model is developed based on management orientation towards external pressure, internal key resources and competitive advantage that can be obtained as the decision factor. The decision-making method used is Analytical Network Process (ANP). The results obtained institutional pressure becomes the criterion with the greatest influence on green supply chain initiatives and sub criteria of customer desires and stakeholder integration having the most significant influence on green supply chain initiatives. There are five green alternative initiatives that can be done: green product design, greening upstream, greening production, greening downstream and greening post use. For green supply chain initiative, greening upstream is the best priority.
