Overall Equipment Effectiveness (OEE) is a method of measuring the effectiveness of the use of equipment. This method is known as an application of a Total Productive Maintenance (TPM) program. The ability to clearly identify the source of problem and it causal factors is the main advantage of this method since the improvement effort becomes focused. Pulp and Paper Industries is one of the manufacturing companies that produce dissolving pulp products (rayon fibre). Based on data from the fibre line department, for the period of January - July 2016, the production process of rayon fibre often experienced constraints due to the high downtime and losses in the pulp machine. This resulted in the use of production process equipment that had not been optimal. It is important to find out the source of the problem and its causal factors before the company makes any improvement effort. This study aims to identify equipment losses and measure the achievement of OEE values in the pulp machine. The measurement result shows that the average of the effectiveness of pulp machine for the period of January - July 2016 was 74.01% and based on Japan Institute Of Plant Maintenance (JIPM) the value has not reached the standard that is > 85%, however, there is still possibility for improvement. The losses that give the most significant effect on the overall equipment effectiveness of the pulp machine is reduce speed that was equal to 27.6%. One way to minimize the losses is by maintaining the actual speed of operation and maintaining wear on each pulp machine roll.

The SAE/ AISI 1045, a type of medium carbon steel, is used most commonly in various structural and element of machines. Sometime, it failed during the in-service, which assumed to be caused by cracking in material as the effect of casting, manufacturing, or heat treatment processes. The current research was developed to find out the effect of hardening and of tempering processes toward hardness, microstructure and cracking. The objectives of the current research are to obtain the effect of cooling rates toward the hardness and cracking and to define a proper cooling media to get a martensite microstructure without cracking of heat resistant products. Results showed that the chemical composition from the spectrometry test confirmed that the specimens were classified as AISI 1045 or JIS S45C. The hardness values properties increased with increase of temperature, except at 1000 °C. The specimens having the hardness property more than that of ASME II standard were not useable due to its brittle.

This study aims to find the empowerment carried out by ITDC management and the Central Lombok Regency Government at every stage of the existence of the KEK Mandalika. This research is very important so that all developments carried out, including the existence of KEKs provide benefits for the welfare of the community in a sustainable manner. The existence of the KEK Mandalika as a tourism zone is absolutely oriented to the economic development of local communities, increasing local values and culture, minimizing the negative impacts of exploitation and social. The research was designed with qualitative research. Community respondents in five affected villages, including village officials. The findings obtained are that ITDC management provides broad opportunities for the community to be involved in development projects, according to the skills they have, but the facts of the willingness and skills possessed are minimal. Empowerment policies to take advantage of the operational stage by local communities, both from the government and ITDC management are still minimal. The role of the government is to use all lines of service and agencies owned to formulate community empowerment policies in realizing adequate awareness and skills, so as to benefit from the existence of the KEK Mandalika. This condition will create a mutually beneficial relationship between the community, ITDC management and the government, where community welfare can be realized, increasing community values and culture will support the existence of the KEK Mandalika. The government and ITDC management must avoid charity policies, but focus on increasing knowledge, awareness and skills in accordance with the existence of international standard KEK Mandalika tourist destinations.
