Abstract

PT XYZ is a heavy equipment rental company and mining contractor. One of its working areas is an open coal mine in South Kalimantan, obtained a contract to lease heavy equipment in the form of 14 (fourteen) Caterpillar 773E Off Highway Trucks. Mine owner have availability targets and application of penalties, PT XYZ must implement appropriate maintenance and maintenance strategies. In 2018, the OHT total down time is 34,061.30 hours. For 15,272.00 hours (44.8%) downtime is caused by major component breakdown. The high cost of repairing components makes it difficult for company management to determine the decision to repair. To meet the heavy equipment availability target of mine owner, PT XYZ must implement appropriate maintenance and maintenance strategies. High off Highway Truck (OHT) availability can be achieved by minimizing downtime. The purpose of this research is to determine a general overhaul (GOH) time interval that has the greatest effect on the availability of Caterpillar 773E Off Highway Truck. In order for minimization of downtime to have a significant impact, it must be determined which critical components have the most influence on costs. Next step is determined the GOH interval by considering the smallest cost impact. The results of research show Caterpillar 773E OHT critical components are engine, transmission, final drive and torque converter. The GOH interval is 17,992.81 hours

Abstract

In order to support offshore aquaculture in Indonesia, a floating net cage is being developed by Pusat Studi Kelautan ITS and will be placed in Sidoasri Village, Malang, Indonesia. The use of floating net cage will shift the habits of the fishermen. It will be very for the effort of developing the floating net cage if it will be rejected by the fishermen. Therefore, it is important to measure the factors influencing fishermen intention as a potential user to use the cage. In this paper, Technology Acceptance Model is integrated with Theory of Reasoned Action to identify the factors. The findings of this study, obtained that fishermen intentions to use floating net cage is influenced by their attitude and subjective norm, while perceived usefulness and perceived ease of use have a role to affect the intentions indirectly

Abstract

The heavy equipment maintenance system cannot be separated from the problems of Human Resources (HR). Some literature has defined HR as a success factor for the successful implementation of maintenance systems. The Asset Maintenance Division as an organization which responsible to maintain the Company's assets routinely, including the Doosan S500’s 50-tonne class excavator. But in fact, excavators that are currently still operated often breakdown and its physical condition are in a bad condition. From the observation of 9 (nine) units excavators, the Key Performance Indicator (KPI) target was still not achieved, especially on the items Mean Time To Repair (MTTR) and Mean Time Between Failure (MTBF). Mechanic’s technical competencies needed in achieving KPI are divided into four sub competencies: Maintenance, Repair & trouble shooting, Remove & install and Overhaul. This study aims: analyzing mechanic’s competencies against company‘s standards, analyzing the influence of mechanic’s competencies on achieving KPI targets, providing recommendations on the influence of mechanic’s competencies for achieving KPI targets. The primary data used in the study were obtained through interviews and the questionnaires as well as secondary data obtained from various literatures, research results and supporting books. The method of processing and analyzing data uses the method of gap analysis and the Non-Parametric Statistics (Multiple Regression). The results of the gap analysis are known that there are still gaps in the actual competence of employees with competency standards set by the company. Factors that cause the competency gap are generally known because of a lack of understanding of the basic skills  required, mastery of work techniques and consistency in applying work quality standards. Recommendations from this study as an effort to improve the skills and knowledge of mechanics to improve work effectiveness that affects MTTR and the quality of work that affects MTBF so that the KPI are consistently achieved

Abstract

In this study the equipment lease contract, where two players, the lessor, lease the equipment to the user (lessee), if the equipment fails to exceed the tolerance agreed by both players during the lease period and needs to be repaired, it is considered detrimental to the lessee, because it results in a loss of potential revenue will be received from leased equipment. Therefore, the total income of the lessor in the lease contract may incur penalty costs as a consequence of the lessor for failure to maintain maintenance performance. We use Nash's game theory formulation to find a win-win solution between players where it is an equilibrium point for lessor and lessee. The results of this study are, when Lessee decides to maximize profits, which is the total potential profit gained by the lessee using leased equipment, and the lessor also decides to maximize their profits derived from the leased equipment by considering penalty cost as a cooperatively determined variable. The selected scenario is the percentage of the minimum penalty cost with the maximum level of equipment used.

Abstract

Chicken slaughter process waste is divided into two types, solid waste and liquid waste. Almost all of the waste generated by the chicken slaughter process can be reused. Lately, Vocational High School in Pasuruan, East Java, has Livestock Agribusiness unit that made a waste treatment program to deal with the problem of waste from the surrounding chicken slaughter process. However, some chicken slaughter process waste cannot be reprocessed and is directly dumped into the sewer due to limited technology. The type of waste that cannot reprocess is blood and chicken feather waste. This research aims to process the waste into high-quality fish food by applying the principle of automation and integrating machines with existing chicken cutting machines. The application of this appropriate technology begins with observing the existing conditions and the process of designing, manufacturing, and testing equipment carried out at Vocational High School in Pasuruan. The research resulted in designing and manufacturing machines that support waste treatment of blood and chicken feathers from Livestock Agribusiness. The machine design consists of three main components: a blood and chicken feather grinder, a vertical mixer, and a fish feed press machine. The expectations of this machine design will support productivity and concern for waste management, which can also build environmentally friendly standards in the Livestock Agribusiness unit of Vocational School in Pasuruan.
