Abstract

Quality and Quality in the manufacturing industry in addition to emphasizing the products produced, it is also necessary to pay attention to the quality and quality of the production process. Thus, the final product produced is a product that is free from defects and there is no more waste that must be paid dearly because the product must be discarded or reworked. To maintain and improve the quality of the products produced, it is necessary to have quality control for the company. With quality control, it is expected that the products produced are in accordance with the standards set and deviations that occur can be immediately overcome. The Six Sigma method is a statistical concept that measures a process related to defects or defects. This method is considered as a method that is able to take a comprehensive approach, which will dramatically improve the quality of the resulting product. With the implementation of the Six Sigma method, CV. Bintang Terang Medan is expected to minimize the number of defective products to zero defects.

Abstract

The availability of job opportunities in Indonesia, especially for citizens who have no skills and low education, has resulted in many Indonesians choosing to become Indonesian Migrant Workers (PMI). So many Indonesian migrant workers want to work in Saudi Arabia. Working as migrant workers is expected to improve the welfare of PMI families in Indonesia, but often PMIs in their placement countries experience acts of physical, verbal, sexual, and economic. Currently, as the number of migrant workers living abroad increases, the Indonesian Migrant Worker Protection Agency (BP2MI) is receiving more complaints from Indonesian Migrant Workers abroad. These Indonesian migrant workers complained about cases such as physical violence, wanting to be returned to Indonesia, unpaid salaries, sexual violence, and so on. In this condition, the role of the Indonesian Government is essential to implement protection for Indonesian migrant workers. Law Number 18 of 2017 concerning the Protection of Indonesian Migrant Workers was enacted to increase protection for Indonesian migrant workers by the Indonesian Government. Based on existing data and news spread in the mass media, it is stated that the number of complaints due to violence against Indonesian Migrant Workers is still high, so this research wants to define the causes of violence experienced by Indonesian Migrant Workers and prove legal protection for Indonesian Migrant Workers based on the Law Number 18 of 2017. The low level of education of Indonesian Migrant Workers means that they often ignore or do not understand the departure procedures for Indonesian Migrant Workers. Legal provisions have been explained in detail in Law Number 18 of 2017, regarding the rights and obligations of Indonesian Migrant Workers; social Security; protective procedures; and the duties and responsibilities of the government, both central and regional governments. The form of protection provided is before, during, and after work. The Ministry of Manpower has developed a program called Village Care for Migrant Workers to increase legal protection for Indonesian Migrant Workers from the Village level even though the program has not been able to run optimally.

Abstract

Scouting is one of the non-formal education methods that plays an important role in building the character of the younger generation. This research aims to analyze the contribution of scouting in character formation, identify the benefits obtained by scout members, and assess the challenges faced in the modern era. Through a literature study approach and analysis of the latest data obtained from books, journals, and articles, this research found that scouting activities not only teach practical skills but also moral values such as discipline, responsibility, and leadership. Participation in scouting has been proven to enhance social skills and a sense of patriotism among teenagers. However, scouting also faces significant challenges, including the lack of interest from the younger generation who are more focused on digital activities. To remain relevant, scouting needs to adopt innovative methods that appeal to the younger generation, such as utilizing digital technology in its programs. This research provides recommendations for the development of more effective scouting programs, thereby attracting more participants and enhancing their impact on national character education.

Abstract

The development of social media has transformed the way Generation Z constructs and presents their self-identity. One emerging phenomenon is the use of more than one Instagram account by a single user, known as the first account and second account. This study aims to analyze the use of multiple Instagram accounts by Generation Z in shaping self-image, using Erving Goffman's dramaturgical theory. This research adopts a descriptive qualitative method with a phenomenological approach. The informants consisted of eight 11th-grade students from SMK Negeri Nusawungu who actively used multiple Instagram accounts. Data were collected through observation, semi-structured interviews, and documentation, and analyzed using Miles and Huberman’s interactive model. The findings show that the first account functions as the front stage, where informants present an ideal image with curated content and carefully managed impressions. In contrast, the second account serves as the back stage, used for freer, more spontaneous, and emotional self-expression, with a more selective and private audience. The seven key dramaturgical concepts—mystification, setting, front personal, role distance, stigma, impression management, and frame analysis—were identified in the online behavior of the informants. This study recommends the importance of digital literacy and social empathy in understanding the dynamics of youth identity in digital spaces.

Abstract

One type of efficient and widely used heat exchanger is the Plate and Frame Heat Exchanger (PFHE). PFHE is a device designed to increase the efficiency of heat exchange through a structure of plates assembled together. This design allows a large heat exchange surface area in a relatively small space, creating an efficient environment for heat transfer. This study took the Plate and Frame type Heat Exchanger object, while the purpose of this study was to determine the performance of the Heat Exchanger in the Sea water & Cooling Water system at PT. Eni. The research methods used were the Observation method, Interview method (Question and Answer), and Literature review. The results of the study showed that the performance of the Heat Exchanger in the Sea water & Cooling Water system at PT. Eni runs according to the desired design. The operating temperature line remains below the maximum limit set, and indicates the performance of the heat exchanger in very good condition. This reflects the optimal heat exchange results in Cooling Water. In accordance with the design operating parameters, the achievement of heat exchange in the minimum range of 4 - 5 ℃ and the maximum limit of redistribution temperature in Cooling Water does not exceed 45 ℃, which indicates that this system operates according to the desired standards

Abstract

This study investigates the dual impact of teacher competence on student academic performance and the development of leadership qualities in Senior High Schools and Vocational High Schools in Kabupaten Serang, Banten Province. Using a qualitative research approach, data were collected through interviews, focus groups, and classroom observations involving teachers and students. The findings reveal that teacher competence encompasses not only mastery of subject matter and pedagogical skills but also emotional intelligence and leadership modeling. Competent teachers create supportive and participatory learning environments that enhance both academic achievement and leadership development among students. The research highlights that effective teachers are those who not only deliver content but also engage students in meaningful ways, fostering a sense of belonging and motivation. This engagement is crucial, as it encourages students to take ownership of their learning and develop critical thinking skills. Furthermore, the study identifies that teachers who model leadership behaviors—such as ethical decision-making, effective communication, and collaboration—significantly influence students' perceptions of leadership and their willingness to adopt similar traits. However, challenges such as limited access to professional development and resource constraints affect the full realization of teacher competence. Many teachers express a desire for ongoing training and support to enhance their skills, yet systemic barriers often hinder their professional growth. The study underscores the need for comprehensive teacher development programs and policy support to improve educational outcomes holistically. These insights are valuable for educators, policymakers, and school administrators aiming to foster academic excellence and leadership skills in students. By prioritizing teacher competence and providing the necessary resources, schools can create an environment that not only promotes academic success but also prepares students to become effective leaders in their communities.

Abstract

Penelitian ini bertujuan untuk menganalisis tingkat kepuasan pelanggan dan kualitas layanan dengan menggunakan metode Importance Performance Analysis (IPA) dan Service Quality Index (SQI). Penelitian ini menggunakan pendekatan kuantitatif deskriptif dengan sampel sebanyak 31 responden dari pelanggan yang dipilih menggunakan teknik purposive sampling. Data dikumpulkan melalui kuesioner yang mengukur lima dimensi SERVQUAL: tangible, reliability, responsiveness, assurance, dan empathy. Hasil analisis SERVQUAL menunjukkan adanya kesenjangan (gap) negatif rata-rata sebesar -0,58, yang mengindikasikan kinerja layanan di bawah harapan pelanggan. Nilai SQI agregat sebesar -2,33 dikategorikan sangat rendah (sangat tidak baik). Analisis IPA mengidentifikasi enam atribut prioritas perbaikan utama yang berada di Kuadran I, yaitu modernitas peralatan, penampilan staf, konsistensi layanan, kecepatan respon, kompetensi staf, dan pelayanan personal. Berdasarkan temuan tersebut, disarankan agar perusahaan memfokuskan sumber daya pada perbaikan keenam atribut kritis tersebut melalui pembaruan teknologi, pelatihan staf berkelanjutan, dan penerapan SOP yang ketat untuk meningkatkan kepuasan pelanggan secara signifikan.
