Abstract

Perkembangan global saat ini membuat semakin pesatnya kemajuan dalam bidang telekomunikasi khususnya dalam mengakses internet. Salah satu industri telekomunikasi yang mengalami perkembangan pesat yaitu perusahaan provider. Kondisi ini mendorong para provider internet di Indonesia terus berlomba dalam memanfaatkan peluang. Para karyawan dituntut untuk bekerja lebih produktif, dimana ini berkaitan dengan beban kerja yang diberikan kepada karyawan menjadi bagian yang penting, terutama bagi mereka yang menjadi tim teknis internal atau tim lapangan. Oleh karena itu, diperlukan adanya pengukuran beban kerja pada setiap divisi demi mengetahui kebutuhan tenaga kerja optimal. Berdasarkan perhitungan Full Time Equivalent (FTE), pekerjaan dalam tim teknis memiliki kategori overload dan underload. Terdapat dua pekerjaan yang memiliki kategori overload yaitu melakukan pendataan perangkat dan juga cabling di POP serta melakukan improvement jalur kabel maupun underground cable. Pekerjaan yang memiliki kategori underload ada tiga, yaitu melakukan instalasi perangkat routing/switching, melakukan pengecekan kapasitas rectifier dan melakukan pengecekan beban arus pada kWh, ACPDB, DCPDB. Masing-masing pekerjaan dengan kategori overload tersebut perlu melakukan penambahan karyawan 2 orang, sehingga secara keseluruhan memerlukan penambahan karyawan sebanyak 4 orang. Pihak perusahaan perlu melakukan perbaikan agar nilai FTE terdistribusi fit atau beban kerja normal adalah dengan mengalokasikan tim dengan nilai FTE underload ke tim dengan nilai FTE overload, sehingga tidak ada gap beban kerja. Dengan demikian pekerjaan dapat diselesaikan dengan baik dan tidak perlu adanya tambahan biaya untuk menambahkan atau merekrut tim teknis baru.

Abstract

 The main goal of education is to provide people with access to the knowledge and skills they need to deal with life's difficulties. Many academic fields, including science, mathematics, and foreign languages. The motivation of students involved in educational activities comes from their own desires. Meanwhile students are more involved in their learning when they actively participate in class activities, discussions, and homework provided. Lecturer competence refers to the knowledge, skills, and capacity of effective subject communication. The problem of this research is whether there is influence from learning motivation and student activity as well as lecturer competence on student achievement. The purpose of this study was to analyze the influence of learning motivation, student activity and lecturer competence on student achievement. This study uses an explanatory survey research method. The research hypothesis will be tested using the structural equation method, namely SEM (Structural Equation Modeling) with an alternative method, namely PLS (Partial Least Square). The results of processing boostraping data, Student activity with learning achievement of 0.328 has a high influence (F-square value close to 0.35). The competence of lecturers with learning achievement of 0.063 has a relatively low influence. Learning motivation with learning achievement of 0.294 has a moderate influence.

Abstract

Perkembangan Industri 4.0 pada lingkungan bisnis yang kompleks membuat organisasi melakukan penyesuaian strategi seiring berkembangnya inovasi otomatisasi, super computer, artificial intelligence, dan fleksibilitas pola kerja berbasis digital. Technology Acceptance Model (TAM) adalah sistem informasi yang membuat model tentang bagaimana pengguna bersedia menerima dan menggunakan teknologi. Model ini pertama kali diperkenalkan oleh Davis pada tahun 1989. Kedua variabel model TAM yaitu kemanfaatan (usefulness) dan kemudahan penggunaan (ease of use) dapat menjelaskan aspek keperilakuan pemakai. Ciri khas dari Model TAM adalah sederhana namun bisa memprediksi penerimaan maupun penggunaan teknologi. Tujuan penulisan paper ini adalah untuk mengamati apakah konsep dan metode tersebut masih relevan serta efektif untuk digunakan berdasarkan literatur pada berbagai sektor industri. Hasilnya menunjukan bahwa TAM adalah model yang dapat menjelaskan bahwa persepsi pemakai akan menentukan sikapnya dalam penerimaan penggunaan teknologi informasi masih sangat relevan untuk digunakan saat ini dalam berbagai sector usaha.

Abstract

In meeting the needs for innovation in the current digital era, PT Stechoq must be able to complete the project according to the set timeline. The high fulfillment of research targets with a limited number of manpower causes the manpower to have to do multiple jobs and work overtime to ensure there are no delays in project completion. The office with the longest working hours at PT Stechoq Robotika Indonesia is the Mejing office with an average working hour of 8.50 hours/day. This study aims to analyze the time and mental workload and calculate the optimal amount of manpower by integrating the FTE & RSME methods. The results showed that the workload of all PT Stechoq research staff, totaling 9 people, was in the excessive workload category. It is proven in the results of calculating the time workload using the FTE method showing a range of 1.47-2.17 which means it is included in the Overload time load category and the results of calculating mental workload using the RSME method have a range of 53.33-93.33 or have an average of 80.74 which means it is included in the category of moderately large mental burden. Then, the calculation results show that the optimal research staff required by the company is 16 manpower. So that an additional manpower of 7 people is needed. With the distribution of additional manpower for Supervisor positions 3 people, for Mechanical Staff positions 2 people, and for Electrical Staff positions 1 person, and for Production Staff positions 1 person.

Abstract

Based on an estimate for 2030, Indonesia's workforce needs are estimated to reach 113,000,000 people. From data from the Central Statistics Agency (BPS) the Open Unemployment Rate (TPT) in Indonesia reached 8.42 million people as of August 2022. The highest TPT, namely 9.42%, was contributed by SMK graduates. Seeing this, an action is needed to align learning in the classroom to suit the needs of the industrial world. The literature review approach is used to find research gaps in the application of lean learning in vocational education using VosViewers. Based on the results of the VosViewers analysis and the SOTA matrix, it was found that the use of SERVQUAL has been quite widely applied in the service sector, but the combination of EDUQUAL and KANO has not been widely studied in the education world, especially in LEAN LEARNING research in vocational education.

Abstract

Indonesia’s rapid growth in nickel processing has led to a significant increase in nickel slag from pyrometallurgical operations. While slag buildup creates environmental and land-use problems, using it in downstream production by small- and medium-sized enterprises (SMEs) has not been studied much. This study examines the technical and financial feasibility of producing paving blocks from nickel slag in a semi-mechanical SME production system. The process uses 85% slag, 10% fly ash, and 5% cement, with a planned capacity of 1,800,000 units per year. The technical review covers material processing steps, equipment details, and steady-state operating capacity. Financial analysis is done over 10 years with a 10% discount rate and standard capital budgeting methods. The total investment needed is IDR 2.16 billion. Results show strong financial performance, with a Net Present Value (NPV) of IDR 4.13 billion, an Internal Rate of Return (IRR) of 25.40%, a Benefit–Cost ratio of 2.91, and a payback period of 30.84 months. The break-even point is 279,886 units, or 21.53% of capacity, showing the system can handle moderate market stress. These results show that the use of SME-based slag is both technically feasible and economically sound, supporting small-scale industrial cooperation and offering a practical way to promote circular integration in Indonesia’s nickel industry.
