1. Introduction

The automotive world has developed rapidly in recent years and it requires creativity and innovation to seize the competition. Every year motorcycle manufacturers launch their new products by adopting the current sophisticated technology in order to compete and to dominate the market. For example, Honda as one of the biggest automotive manufacturer has several patented technology, such as Programed Fuel Injection (PGM-FI), Enhanced Smart Power (ESP) technology, swit stand, combi break system, Idling Stop System (ISS), Alternating Current Generator (ACG) starter.[3]

To respond the challenges of this technological advancement, vocational high school (Sekolah Menengah Kejuruan or SMK) plays an important role. Since SMK as a work oriented education program with one of its missions is to improve the quality of graduates in accordance with National Competency Standards.[7]. Vocational education is trying to prepare competent individuals to be able to develop careers in the future. However, it has not been completely achieved. The Central Bureau of Statistics in 2015 noted that the number of unemployment in Indonesia in August 2015 has increased into 110 thousand people becoming 7.56 million people from 7.45 million people in February 2015. Surprisingly, it is dominated by SMK graduates and the unemployment rate for vocational education occupies the highest position with 12.6%.

This condition is triggered by the lack of student competence in the working process, which is known during their internship or industrial work practices. Most of motorcycle companies that receive and train apprentices find that many students are inadequate to master knowledge and skills, especially in tune-up, electricity, and devices measurement. The students also often make mistakes in performing their work, such as periodic maintenance procedures of tune-up (checking and repairing), analyzing the problems on engine malfunction, determining the usage duration and the wear parts that must be replaced. The lack of competence has an impact with the indication of the increase in unemployment rate from SMK graduates. The problems mentioned above become one of the important signal for immediate improvement and change.

Education is a manifestation of dynamic human art and culture as well as the development requirement, therefore the change or the development of education should be followed and influenced by changes in all aspects of society (economy, science and technology, socio-cultural),[9]. the knowledge that is obtained in the form of facts, concepts, procedures and principles of the students can be so by involving interaction with external environment that can change someone's behavior.[12]. Changes, in the meaning of improving the educational process at all levels, need to be continuously done to anticipate of future interests.

To reduce the gap between the demands of industry-defined capability and the material learned in SMK, it requires the relevance from both parties to bridge the difference. An effort that can be made, such as by having industry assessment on the material that need to be given to vocational students as prospective workers. In addition, it is necessary to evaluate the material on SMK curriculum to answer the needs of the world of work. This relevance and the evaluation process can assist SMK in preparing ready-to-use graduates. The materials should be tailored to the community needs, the workplace needs, as well as it should be fun and interactive to build student skill competencies effectively. The learning materials in SMK presented in various competencies are important for the students' future. Those competencies are required to become intelligent Indonesian and competent workers based on the competency standards established by industry, business world and professional associations. To achieve the standard of competence, the material content should be packed in groups of subjects and organized into normative, adaptive and productive program.

Motorcycle engineering department in SMK is designed to teach and to improve the competence of motorcycle engineering expertise. The Law of National Education System Article 3 and 15 states that vocational education is a secondary education that prepares students to work in a particular field. Specifically, the competence objective of motorcycle engineering expertise is to equip students with the skills, knowledge and attitude to be competent in the areas of maintenance and repair of motorcycle on a) engine, b) power transfer system, c) chassis and suspension, d) electrical systems.

The competence of motorcycle engineering in this research is related to competence for 4-stroke engine motorcycle. It includes in the category of motor fuel. The combustion engine is a kind of heat engine that converts the chemical from fuel into mechanical power and the conversion is carried out in the machine inside.[4]. In general, combustion engines in the ICE (Internal Combustion Engine) consists of two types of motor 4 and 2-stroke engine, each type has its own advantages and disadvantages. 4-stroke engine performs four steps process of suction, compression, power, and exhaust, twice crankshaft, one-time camshaft rotation and one burning or power.

The machine in motorcycle needs to be taken care to keep the engine in top performance. Tune-ups and schedules service that marginal and out-of-tolerance adjustments are routinely corrected.[1] Tune-up is part of regular maintenance activities on motorcycles, which include: a) examining the parts of the motorcycle to make sure it functions properly, b) cleaning the dirty parts to prevent the system damage c) setting the changed parts to match the specifications. d). repairing or replacing the wear parts. Tune-up consists of inspecting, testing, and adjusting the motorcycle. [1]. The part that get tune-up cover 1) fuel channel, 2) fuel filter, 3) hand gas system, 4. carburetor, 5) air filter, 6) spark plug, 7) swing valve, 8) engine oil, 9) oil filter, 10) stationary machine rotation, 11) chain wheel, 12) battery liquid (battery water), 13) oil brake discs, 14). wear of brake shoe, 15) brake system, 16) rear brake light switch, 17) headlights direction, 18). coupling System, 19) side-stand, 20) front & rear suspension, 21) bolt & fastener, 22) wheels or tires, 23) steering wheel head.

The urgency of competent labor of motorcycle engineering expertise from vocational high school is affected by the advancement of technological transformation. It makes the learning materials analysis should be done to support the knowledge and ability of vocational high school students in order to compete future work world. This analysis is also expected to be a reference for teachers and relevant to improve the competence of vocational high school students, especially for the motorcycle engineering field. The purpose of this study is to explain the scope of the practice material of 4-stroke engine motorcycle tune-up for motorcycle engineering department of SMK in order to fulfil the needs of the industry and the world of work.

2. Research Methodology

This research can be categorized as descriptive quantitative which is explorative without hypothesis. The research analysis used DACUM approach where Developing Curriculum is the most effective analytical technique. It is usually used by industry practitioners, educators and consultants to identify tasks, jobs and information related to jobs and jobs.[10], [7]. The research sample consisted of mechanic, head of workshop, service advisor at authorized Honda workshop (AHASS) amounted to 24 respondents from 6 workshops, 6 vocational teachers of motorcycle engineering from 2 vocational high school, so that the total sample was 30 respondents. The questionnaires was to measure the strength and weakness of the material scope of 4-stroke engine motorcycle tune-up using the respondents' opinion about the importance of material presented in the questionnaire.

The content validity test was performed by 5 experts. The points that must be considered by the expert in reviewing the contents of the instrument including 1) the instrument should be based on the indicator, 2) the item is written short and clear, 3) the choice is in the form of good order numbers, 4) the similar component of each item is given the same score (the same score does not mean the answer option is similar), and 5) the item is written with the standard language.[8]. After having the expert validation analysis, this descriptive instrument met a very good criterion and can be used without revision meanwhile, for its reliability, the score was 0.679 with significance at 0.019, It mean then the overall instrument was declared valid and reliable

The analysis of learning material requirement of 4-stroke engine motorcycle tune-up was not expressed in terms of respondent's level of achievement of the percentage. The decision criterion were using the selected learning materials of 4-stroke engine motorcycle tune-up practice and it had the respondent's level of achievement which was more than 50% from the category of “very important” and “important”,[7]. The results of the respondents' level of achievement was, then, compared with the current motorcycle learning materials in the vocational high school. The research decision making was the learning material found in the requirements analysis with the percentage of more than 50%, and, as the research finding, it can be used as reference for the curriculum structure changes or the additional material on motorcycle engineering for tune-up practice.

3. Result and Discussion

The needs analysis is done to get a real picture on the job field of the expected competence in accordance with the employment needs,[7]. There are some skills that are demanded in the industry and manufacturing, the skills need will be very important as the defense of the information development and the environment rapidly. It shows that the specificity is very crucial in the industry or working world and it should be used by education institutions to be able to adapt to the current technology and today's people needs.

The respondents' responses on the learning materials for the 4-stroke motorcycles tune up categorized as “very important”, “important”, “less important”, and “unimportant” to each item of the material. Furthermore, their 'answers were divided into “very important” and “important” category with “less important” and “unimportant” categories. It was to separate the learning materials considered important by the respondents which should be learned by the vocational students and the unnecessary one. The data showed that “important and “very important” category reached above 50% and 100 subjects/ sub topic material fell into the category of “very important” and “important”. This category of “very important” and “important” then compared with the materials of 4-stroke motorcycles tune up in the current SMK curriculum. The recommended learning materials had not been listed in the SMK curriculum and those were considered very important to be taught to the vocational high school students of motorcycle engineering program.

Based on the comparison data on the material coverage, it was found that some material did not include yet in the syllabus of 4-stroke motorcycle tune-up subjects of vocational high school. The recent syllabus only covered 35 topics/ sub topics of material while, based on the research result, it should be 100 topics/ sub topics. It means the recommended material that should be added as much as 65 topics/ sub topic. Below are the topics/ sub topics based on the research findings.

The need analysis in this research is to know the gap between the expectation and the reality in the school & the industry. The competence of vocational education can be effective if the students in the learning process are taught through a real experience to create behavior, thinking and good actions in the work,[11]. Based on that view, the vocational education must create learning conditions in accordance with the real work field and provide learning in accordance with the needs of the world of work to make sure the vocational education students meet the labor market. Vocational education as part of education which makes an individual more employable in one group of occupations the other [5], [2]. The education in the future should have the goals and orientations to socialize people into appropriate attitudes for the world of work, as well as to orientate people to understand the world of employment and to prepare for the choices and transition that they will have to make to entering it, prepare them with specific skills and knowledge to apply in a direct way after becoming employment.

The need analysis findings on the materials of 4-stroke engine tune-up of motorcycle engineering on vocational high school need to be followed up by the school policy maker. The facts and reality show that a lot of material is still not covered all in the syllabus material 4-stroke engine motorcycle tune-up. The immediate evaluation should be made in case of the materials in the school curriculum to avoid the decrease on the students' competence. The development of automotive technology is so rapid that demand the education institution to improve the materials and the learning process aligning with the community needs as well as to improve the competence of vocational high school students.

4. Conclusion

Based on the research result, it can be concluded that the scope of practice material of 4-stroke engine motorcycle tune-up on the motorcycle engineering of vocational high school in the current curriculum has 35 topics/ sub topics of material while the “very important” and “important” category of the materials is 100 topics/ sub topics. The results of this study indicate that there is a gap between the learning materials in the school with the industrial needs. Therefore, the existing learning material of 4-stroke engine motorcycle tune-up need to be improved to enhance the competence of the vocational students
