Abstract

Rapid growth is being experienced by the automotive industry in Indonesia. A significant challenge for vocational school education is the increasing demand for skilled and relevant human resources in order to respond to the challenges of the Industrial Revolution 4.0. Students at SMK Daya Wangsa Wonogiri's Heavy Equipment Engineering Vocational School have difficulty mastering product design competencies due to limited technology and learning methods that focus on reverse engineering technology. Therefore, reverse engineering training based on industrial products is necessary to provide students with various product development skills.  This training method includes: 1) Introduction to reverse engineering; 2. Use of 3D scan as an advanced tool in reverse engineering; 3. Reverse engineering project; 4. Project presentation, and 5) Evaluation. This program is expected to provide technical skills that are competitive with the current state of the automotive industry. Results show that students exhibit excellent technical perception, attitude, and motivation toward this technology. This program can support improving the quality of vocational education through reverse engineering technology. In the future, it can establish SMK as a center of excellence by promoting applied technology.

Abstract

This study aims to explain how far the effectiveness of participatory election-based supervision took place in the election of Governors and Deputy Governors of the 2017 Bangka Belitung Islands Province. The debate is becoming more and more complexes and more complexes when the idealism of the existing surveillance system collides with the real context of the field of reality. The problem will become so complicated when the theoretical conceptual building fails to explain and even becomes a guide in engineering its ideal political reality. To conduct these study qualitative descriptive research methods will be used. Primary data sources will be obtained through non-participant observation and in-depth interviews whose information is determined by purposive sampling. To help analyze this study, the theory of participatory supervision will be used which includes electoral reform and local democracy, contextualization of participatory engagement. Data analysis techniques are carried out with the stages of collecting, reducing, displaying and drawing conclusions.

Abstract

Effective leadership is determined not only by a leader’s managerial abilities or technical skills, but also by the moral qualities and character that underpin their leadership. One key concept that emphasizes the moral dimension of leadership is the principle of “The Law of Solid Ground,” as articulated by John C. Maxwell. This principle asserts that trust is the primary foundation supporting the entire structure of leadership. Without trust, leadership loses its moral legitimacy and its influence over followers.  This article aims to theoretically analyze the concept of the Law of Solid Ground within Maxwell’s leadership theory and explore its implications for effective leadership practice. This study employs a literature review (library research) method, utilizing a conceptual analysis of Maxwell’s works alongside a critical dialogue with modern leadership literature from various experts.  The results of the study indicate that trust is a fundamental element of effective leadership and that a leader’s character integrity is a key factor in building that trust. Integrity fosters credibility, strengthens the moral legitimacy of leadership, and fosters a healthy and sustainable organizational culture.

Abstract

Berahan Kulon Village, apart from being known as a fishing and fish farming village, also has Micro, Small and Medium Enterprises (MSMEs) that produce herbal drinks known as Jamu Coro. Jamu Coro is made from rice flour and spices such as ginger, lemongrass, cinnamon, coconut sugar and coconut milk. This traditional drink has existed since the days of the Bintoro Sultanate and was served at meetings or events at the Demak Bintoro palace at that time. The existence of wedang herbal medicine coro is still maintained and preserved by the community. They are the conservators of herbal coro in Berahan Kulon Village by making herbal products in powder form. These MSMEs have problems with production equipment that is still completely manual and the production process is not good or hygienic. The problem is the quality of coro herbal products which are in the form of non-uniform powder. SMEs also find it difficult to develop large orders. Based on the society team at Sebelas Maret University, it intends to help SMEs Situ Jamu through the Community Partnership Program. It is hoped that it can improve the quality and quantity of herbal coro in powder form and improve the economy in Berahan Kulon. An output will be obtained in the form of appropriate technology for supporting the production of coro herbal medicine

Abstract

The development of this fast era makes competition to get a job to increase and become more difficult. In the current competition in the industrial world, it demands an increase in the quality of Human Resources through education. Vocational High School Education also prepares its graduates to go directly into the world of industry, but there are still limitations between the need for human resources in industry and the human resources produced by educational institutions. So therefore Curriculum development in Vocational High Schools is developed by prioritizing the needs of society, one of which is the need to be able to compete directly in industry. The aims of this research are: (1) To find out the alignment process between the SMK curriculum and industry. (2) Knowing how far the curriculum in SMK is aligned with the world of work in industry. (3) Knowing whether the SMK curriculum with industry is feasible.  The method used in the automotive concentration curriculum alignment activities at SMKs uses a qualitative approach with descriptive research. Data collection techniques using techniquespupose sampling. Data collection techniques in this study used data collection techniques in the form of interviews, documents, and observations. The research documents include the Merdeka Curriculum, K13 Curriculum, service books, vehicle inspection sheets, and the results of the FGD minutes. Data analysis techniques in this study used content analysis techniques (analysis content). The research locations were limited to 2 SMK, namely: SMKN 2 Surakarta and SMK Warga Surakarta and three industries, namely: Toyota Nasmoco Ringroad, Daihatsu Adi Sucipto, and Suzuki Pabelan (PT. Solo Indonesia Utama). The data obtained is then juxtaposed between the curriculum and competencies in the industry in tabular form so that it can be seen which curriculum and competencies are not aligned. The results of this study are: The curriculum between automotive engineering vocational schools and industrial competencies is aligned, this is evidenced by the existenceforum grub discussion (FGD) between the SMK and the automotive industry.

Abstract

The use of a steam carburetor is one way to reduce exhaust gas emissions where it works by mixing fuel and air in the room with an evaporation process so that the air and fuel mixture is more homogeneous. This study aims to see (1) the effect of using a steam carburetor on exhaust gases on a Supra X motorcycle; (2) the effect of using variations in exhaust gas emissions on the Supra X motorcycle; (3) the effect of using steam carburetors and fuel variations on the exhaust emissions of the Supra X motorbike. This research is a research, quantitative, descriptive, comparative, with experimental methods. The research used the 2x2 method which consists of independent variables using steam and conventional carburetors as well as variations of pertalite (RON 90) and pertamax (RON92) fuel. Exhaust gas emission testing is guided by the Indonesian National Standard (SNI) with three repetitions, for 20 seconds times the test The results of the study are as follows: First, the use of a steam carburetor produces lower exhaust emissions compared to conventional carburetors on a 100cc Supra X motorcycle. Second, pertalite fuel (RON 90) produces lower exhaust emissions compared to Pertamax fuel (RON 92). Third, the effect of using the type of carburetor and the type of fuel that produces the lowest exhaust emission, namely the steam carburetor using the combined splash and bubbling method with pertalite fuel with an average of 0.52% CO and 273.67ppm HC.
