Abstract

PT. X is a company engaged in the oil industry. The oil produced is palm oil. This palm oil company has been established since 1970, but in February 2021 it was acquired. PT. X is currently focusing on innovating new products that will be launched in the near future. The product launch also coincided with the high demand for palm oil starting in October as much as 23.5% compared to the previous month. The company realizes that employee performance needs to be maximized considering the increasing demands of work. Companies want to know whether employees are ready for many demands by looking at the employee's attachment to the company. Company engagement can be measured by several factors, namely work demands, company support, and support from each individual. Questionnaires were distributed to collect data to all employees from various divisions in the company. The conclusion obtained is that job resources and personal resources have an impact on company employees. This impact is a good thing considering that the high job resources compared to job demand has a positive impact on the possibility of employees experiencing burnout or leaving their jobs to be small.

Abstract

The purpose of this final project is to design the control of the spread of the corona virus in the classroom. The method used is descriptive research, literature study and extracting protocol information from various literatures. The control design consists of several stages, namely seeking information through literature studies to identify potential points of exposure to COVID-19 in the classroom, identifying causes of failure, identifying the impact or risk of failure. After identifying new problems, an assessment stage is carried out to look for possible impacts or risks so that a control design will be made as a solution. The results show that there are 9 controls that will be designed to control the spread of COVID-19 in classrooms and the final result of this final project produces suggestions for protocol stages according to government standards and universities or schools that have carried out offline learning in the new normal period.

Abstract

This research was conducted to design a value assessment at PT. XYZ using the Rasch method. Assessment Value is a measuring tool created to identify and measure the suitability of the candidate's work value. The purpose of making a value assessment is to obtain an assessment design and determine the suitability of the candidate's values with company values. The Rasch method is used to assist research because it facilitates dichotomous data. Dichotomy data consists of two answers, for example, yes or no answers in the assessment. The trial was carried out to obtain an assessment design, which consisted of statistical tests in the form of validity and reliability tests and verification from the user. Test the validity and reliability using computational assistance from the Rasch method on Winstep software. The item assessment validity test is carried out with the help of the item function, while the reliability test uses the summary statistic function in Winstep. User verification is carried out to determine whether the value assessment made is in accordance with the needs and the company's values. The results of the value assessment later can help the company to identify the suitability of the candidate's work culture with the company.

Abstract

Sebagai salah satu produsen komponen alat berat terbesar, PT X memiliki berbagai macam produk dan fasilitas yang harus dikontrol. Sayangnya, karena banyaknya variasi proyek, fasilitas, dan produk, maka pemantauan terhadap progres dan kelengkapan dokumen yang dibutuhkan menjadi sulit. Oleh karena itu, penelitian ini dilakukan untuk mengembangkan dan merancang sistem informasi digital pada bagian Manufacturing Engineering Section Engineering Development dan Production Engineering Department. Untuk mencapai tujuan tersebut, digunakan pendekatan DMAIC (Define, Measure, Analyze, Improve, Control) sebagai basis kerja dalam proses penelitian dan total quality management (TQM) sebagai kontrol untuk perbaikan berkelanjutan. Beberapa akar penyebab ditemukan melalui analisis diagram tulang ikan. Dari semua faktor tersebut, faktor metode menjadi fokus permasalahan utama yaitu, “belum adanya standar dalam penyimpanan dokumen dan penyampaian informasi”. Untuk mengatasi permasalahan tersebut, maka diajukan usulan penerapan perbaikan berupa sistem kerja baru yang didukung dengan pengembangan website internal perusahaan. Usulan tersebut, setelah diuji pada kondisi lapangan secara langsung didapatkan capaian dokumentasi 100% dan penyebaran informasi terstandarisasi dan terdigitalisasi.

Abstract

Dalam upaya meningkatkan kepuasan pelanggan, proses desain produk harus secara efektif mampu menangkap dan menerjemahkan harapan dan kebutuhan pelanggan. Quality Function Deployment (QFD) adalah metode yang sering digunakan untuk membantu proses ini, tetapi implementasi QFD konvensional terkadang tidak optimal dalam mengakomodasi berbagai kriteria keputusan yang kompleks. Oleh karena itu, penggunaan metode Multi Criteria Decision Making (MCDM) seperti Analytic Hierarchy Process (AHP), VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR), dan Decision Making Trial and Evaluation Laboratory (DEMATEL) penting untuk meningkatkan efektivitas analisis QFD. AHP digunakan untuk memprioritaskan kebutuhan pelanggan berdasarkan minat relatif, sedangkan VIKOR membantu dalam menentukan solusi kompromi terbaik antara beberapa alternatif desain. DEMATEL, di sisi lain, memetakan hubungan sebab-akibat antara berbagai kriteria desain atau persyaratan teknis, sehingga membantu memahami interaksi yang lebih dalam dalam elemen desain. Kombinasi ketiga metode ini memungkinkan desainer produk untuk lebih tepat dalam menangkap ekspektasi pelanggan, sekaligus memberikan solusi desain yang optimal bagi produsen, baik dari segi kualitas, biaya, maupun efisiensi.

Abstract

This study develops an incentive mechanism model for outsourced personnel in product quality inspection, based on a principal-agent relationship. The core challenge lies in misaligned incentives, where agents often prioritize output volume over quality. By integrating Mechanism Design Theory (MDT) and Linear Programming (LP), our model aligns the principal's objective of minimizing defective products with the agent's utility maximization, subject to Incentive Compatibility and Individual Rationality constraints. Our analysis reveals that the optimal incentive structure combines a basic wage with a performance-based bonus. The optimal effort level of outsourced personnel increases with both rising losses due to defective products and enhanced detection effort effectiveness. The model also shows that optimal inspection allocation should be assigned to personnel with higher capabilities, especially for high-risk products. This research provides a theoretical contribution by integrating MDT and LP for incentive design and offers practical implications for improving product quality through a measurable incentive framework.
