Baja karbon ST 40 sering digunakan dalam industri pembuatan kapal, khususnya untuk konstruksi lambung dan dek kapal. Mengingat bahwa lambung adalah bagian pertama dari kapal yang bersentuhan langsung dengan air laut, maka bagian ini memiliki risiko tinggi terhadap korosi. Penelitian ini bertujuan untuk mengetahui laju korosi baja karbon ST 40 (40 mm x 40 mm x 4 mm) dalam sampel air laut yang diambil dari Pelabuhan Gresik. Korosi sangat memengaruhi umur pakai baja dan besi, sehingga penelitian ini menjadi penting. Penelitian ini menggunakan metode kehilangan berat (weight loss method) dan proses perendaman dengan menggunakan pengaduk magnetik (magnetic stirrer) dan tanpa pengaduk magnetik untuk mengukur laju korosi. Pengukuran dilakukan setiap 7 hari selama 28 hari. Hasil penelitian menunjukkan bahwa laju korosi tertinggi terjadi pada air laut dengan pengaduk magnetik, dengan nilai laju korosi (CR) sebesar 13,72 mpy, sedangkan laju korosi terendah terjadi pada air laut tanpa pengaduk magnetik, dengan nilai CR sebesar 0,19 mpy. Selain itu, analisis regresi linier menunjukkan bahwa laju korosi pada air laut dengan pengaduk magnetik adalah -37 mg/cm², dibandingkan dengan -6,06 mg/cm² tanpa pengaduk magnetik. Temuan ini mengonfirmasi bahwa penggunaan pengaduk magnetik mempercepat laju korosi pada baja karbon ST 40.

This study aims to analyze the technical efficiency of herbal product sales at PT X, Sleman branch, with a focus on determining the most efficient input and output variables. The research adopts a descriptive quantitative approach, utilizing the Data Envelopment Analysis (DEA) method to measure efficiency. Several input variables are assessed, including the number of active employees, basic salary, allowances, and bonuses, while the output variable considered is the total amount of herbal product sales. The results, obtained through efficiency measurement using the WinDEAP software, reveal that 50% of the Decision-Making Units (DMUs) are inefficient. Specifically, DMU 1, DMU 3, DMU 4, DMU 5, and DMU 6 fail to achieve optimal efficiency levels. To address this, recommendations for improvement are provided by referring to the efficient DMUs. These recommendations involve tailored input and output adjustments aimed at optimizing sales. Efficiency can be realized if each employee earns a salary of Rp 4,109,733.00 while achieving a minimum sales target of 146 herbal products. Following these recommendations, an assessment of employee performance is conducted. The findings indicate that 30% of marketing employees demonstrate efficient sales performance, whereas 70% still struggle to reach efficiency targets, necessitating further adjustments.

In the public sector, sustaining high levels of employee performance remains a continual challenge, especially amid growing administrative demands and expanding workloads. Disruptions to work-life balance and misaligned organizational values can weaken employee commitment and effectiveness. This study explores the impact of work-life balance and organizational culture on employee performance, with employee engagement examined as a mediating factor. The research was conducted at the Personnel and Human Resources Development Agency (BKPSDM) of Jember Regency using a quantitative explanatory approach and involved a census of 46 civil servants. Data were collected through surveys, interviews, and observations, and analyzed using path analysis techniques to assess both direct and indirect effects. The results show that work-life balance and organizational culture significantly influence engagement and performance. Moreover, employee engagement was found to partially mediate the relationship between the independent variables and employee performance. These findings point to the importance of creating supportive work environments and fostering a culture that promotes collaboration and engagement. Practical steps may include enhancing schedule flexibility and improving team dynamics. Future studies are encouraged to explore additional mediators and expand the research across various government institutions to strengthen generalizability.
