Abstract

PT. GBSI is a company that operates in the security services business (outsourcing) and serves its customers based on work contracts per certain period (project), it’s classified in Project Based Organization (PBO) category. Project Management Maturity Model (PM3) is a tool widely used to measure project management performance by looking more broadly at 10 knowledge areas in project management. This research aims to perform an analysis by PM3 maturity level in PT. GBSI. PM3 is used to measure PBO performance in the construction, IT, biotechnology sectors, and currently, it has begun used in service sector, education, and public administration, but there has been no research using PM3 in the provider of security services sector. This research tries to use qualitative approach through interview, document analysis, focus group discussion in diagnosing conditions at PT. GBSI, and use PM3 assessment analysis. The assessment results show the average maturity level achievement in all areas for project management organization is 30% from target maturity level 2. The assessment result can identify the maturity level in the organization and therefore identify development needs in 10 knowledge areas PM3, also provide alternative human processes, technostructure, and human resource interventions to cover the gap maturity level for organizational development.

Abstract

Corrosion is a metal degradation process caused by chemical or electrochemical reactions between metals and their surrounding environment. This phenomenon leads to significant technical, economic, and environmental losses in various industrial sectors. The use of synthetic corrosion inhibitors that may cause environmental hazards has encouraged the development of environmentally friendly corrosion inhibitors known as green inhibitors derived from natural materials. This study aims to analyze the effectiveness of plant-based extracts as corrosion inhibitors for steel through a comparative literature review approach. The research was conducted using a systematic literature review by analyzing 30 scientific articles published between 2015 and 2024 obtained from databases such as Scopus, ScienceDirect, and Google Scholar. The analysis focused on several parameters including types of natural materials, active compounds, adsorption mechanisms, inhibition efficiency, and optimum concentration. The results show that mangosteen peel (Garcinia mangostana), papaya peel (Carica papaya), and banana peel (Musa paradisiaca) have significant potential as green corrosion inhibitors with inhibition efficiencies reaching 93–95%, 78–83%, and 65–72% respectively. Active compounds such as tannins, flavonoids, pectin, and alkaloids contribute to the formation of a protective adsorption layer on the steel surface that reduces corrosion rate. These findings indicate that natural materials have strong potential as environmentally friendly and sustainable corrosion inhibitors for future industrial applications.

Abstract

Penelitian ini bertujuan menganalisis pengaruh sistem penilaian kinerja dan umpan balik terhadap kepuasan kerja karyawan di sektor ritel. Latar belakang penelitian ini adalah pentingnya sistem evaluasi yang adil dan objektif dalam meningkatkan motivasi serta kepuasan kerja. Metode yang digunakan adalah pendekatan kuantitatif dengan survei terhadap 30 karyawan aktif, menggunakan kuesioner sebagai instrumen pengumpulan data. Analisis dilakukan dengan regresi linier berganda menggunakan SPSS versi 25. Hasil penelitian menunjukkan bahwa sistem penilaian kinerja berpengaruh positif signifikan terhadap kepuasan kerja, demikian pula umpan balik yang diberikan secara objektif dan membangun. Secara simultan, kedua variabel menjelaskan 82,6% variasi kepuasan kerja karyawan. Penelitian ini menyimpulkan bahwa penerapan sistem penilaian dan umpan balik yang efektif dapat menciptakan lingkungan kerja yang produktif serta meningkatkan kesejahteraan karyawan. Hasil studi ini diharapkan menjadi masukan strategis bagi manajemen perusahaan ritel dalam merancang sistem evaluasi kinerja yang lebih transparan dan konstruktif.

Abstract

Penelitian ini dilatarbelakangi oleh pentingnya peran sumber daya manusia dalam meningkatkan kepuasan kerja karyawan sebagai faktor pendukung keberhasilan organisasi. Kepuasan kerja dipengaruhi oleh berbagai aspek, di antaranya manajemen talenta, kepemimpinan laissez-faire, dan lingkungan kerja. Penelitian ini bertujuan untuk menganalisis pengaruh manajemen talenta, kepemimpinan laissez-faire, dan lingkungan kerja terhadap kepuasan kerja karyawan PD. Alam Aneka Aroma Kota Sukabumi. Penelitian menggunakan pendekatan kuantitatif dengan metode survei terhadap 32 karyawan sebagai responden melalui kuesioner skala Likert. Data dianalisis menggunakan regresi linier berganda, uji parsial (uji t), uji simultan (uji F), koefisien determinasi, serta analisis jalur dengan bantuan SPSS. Hasil penelitian menunjukkan bahwa secara parsial manajemen talenta dan lingkungan kerja tidak berpengaruh signifikan terhadap kepuasan kerja karyawan, sedangkan kepemimpinan laissez-faire berpengaruh positif dan signifikan terhadap kepuasan kerja. Secara simultan, ketiga variabel independen berpengaruh signifikan terhadap kepuasan kerja karyawan. Temuan ini mengindikasikan bahwa peran kepemimpinan menjadi faktor dominan dalam meningkatkan kepuasan kerja, sementara manajemen talenta dan lingkungan kerja perlu dioptimalkan agar memberikan kontribusi yang lebih efektif bagi pengelolaan sumber daya manusia.
