Abstract

Terantang is commonly found growing in the peat swamp forests of Central Kalimantan. It holds significant economic value in the wood processing industry; however, it has low durability, requiring preservation treatments to enhance its wood quality. This study aims to analyze the impact of Gelam wood liquid smoke concentration and the radial direction of Terantang wood on its physical properties, particularly wood weight and specific gravity, after being stored outdoors under shaded conditions for 5 weeks. A factorial Completely Randomized Design (CRD) was employed, incorporating two factors: liquid smoke concentration (0%, 10%, 20%, and 30%) and radial direction of the wood (near the bark, middle, and near the pith). The data were analyzed using ANOVA, followed by Tukey’s HSD test to determine significant differences between treatments. The results indicated that increasing the concentration of liquid smoke significantly enhanced both the wood weight and specific gravity. The 30% liquid smoke concentration produced the highest increase in specific gravity (0.5240 g/cm³). The radial direction of the wood also had a significant effect, with the near-pith section showing higher specific gravity. The interaction between liquid smoke concentration and radial direction significantly influenced the wood weight. These findings suggest that Gelam wood liquid smoke is an effective natural preservative that can significantly maintain the physical quality of Terantang wood stored outdoors under shaded conditions for 5 weeks, specifically in terms of wood weight and specific gravity. This method shows potential for use in sustainable wood processing industries.

Abstract

Penelitian ini bertujuan menganalisis sistem persediaan bahan baku dan proses produksi pada Aldi Mandomai Meubel di Kota Palangka Raya serta mengevaluasi efisiensi biaya persediaan menggunakan metode Economic Order Quantity (EOQ), Safety Stock (SS), dan Reorder Point (ROP). Penelitian menggunakan metode deskriptif dengan pendekatan kuantitatif dan kualitatif. Data diperoleh melalui observasi, wawancara, dan dokumentasi terkait pembelian, penggunaan, biaya pemesanan, serta biaya penyimpanan bahan baku. Bahan baku utama yang digunakan meliputi kayu ulin, benuas, meranti, dan kayu lokal bandsaw. Hasil penelitian menunjukkan bahwa sistem persediaan bahan baku pada perusahaan masih dilakukan secara manual berdasarkan pengalaman manajerial sehingga belum optimal dalam pengendalian biaya persediaan. Hasil analisis EOQ menunjukkan jumlah pemesanan bahan baku yang optimal sebesar 4,6 m³ setiap kali pemesanan dengan frekuensi pemesanan sebanyak 14 kali per tahun. Perhitungan Safety Stock sebesar 14,83 m³ dan Reorder Point sebesar 15 m³ menunjukkan batas persediaan minimum untuk melakukan pemesanan kembali guna menjaga kelancaran produksi. Total biaya persediaan menggunakan metode EOQ sebesar Rp1.391.086 per tahun, lebih rendah dibandingkan sistem perusahaan sebesar Rp4.350.000 per tahun, sehingga diperoleh penghematan biaya sebesar Rp2.958.914 per tahun. Penerapan metode EOQ, Safety Stock, dan Reorder Point terbukti mampu meningkatkan efisiensi pengendalian persediaan bahan baku serta mendukung kontinuitas proses produksi pada industri mebel.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh Job Description dan Pengembangan Karir terhadap Motivasi Kerja dan Kinerja Karyawan, serta menguji peran mediasi dari Motivasi Kerja terhadap hubungan antara Job Description dan Pengembangan Karir terhadap Kinerja Karyawan pada PT. Patra Trading di Jakarta Pusat. Penelitian ini menggunakan pendekatan kuantitatif dengan jumlah responden sebanyak 125 orang yang merupakan karyawan aktif perusahaan. Teknik pengumpulan data dilakukan melalui observasi, wawancara, dan penyebaran kuesioner. Data dianalisis menggunakan aplikasi SmartPLS versi 3.2.9 untuk menguji hubungan antar variabel. Hasil penelitian menunjukkan bahwa Job Description dan Pengembangan Karir berpengaruh positif dan signifikan terhadap Motivasi Kerja dan Kinerja Karyawan. Selain itu, Motivasi Kerja terbukti memiliki peran sebagai variabel mediasi yang memperkuat pengaruh tidak langsung dari Job Description dan Pengembangan Karir terhadap Kinerja Karyawan. Temuan ini mengindikasikan bahwa kejelasan tugas serta peluang pengembangan karir yang terstruktur dapat meningkatkan semangat kerja dan produktivitas karyawan. Oleh karena itu, manajemen perusahaan disarankan untuk memperhatikan aspek perencanaan tugas dan pengembangan potensi individu guna meningkatkan kinerja organisasi secara menyeluruh.   This study aims to analyze the influence of Job Description and Career Development on Work Motivation and Employee Performance, as well as examine the mediating role of Work Motivation in the relationship between Job Description and Career Development on Employee Performance at PT. Patra Trading in Central Jakarta. A quantitative approach was employed with a total of 125 active employees as respondents. Data collection techniques included observation, interviews, and questionnaire distribution. The data were analyzed using SmartPLS version 3.2.9 to examine the relationships among variables. The results revealed that both Job Description and Career Development have a positive and significant effect on Work Motivation and Employee Performance. Furthermore, Work Motivation was proven to mediate the indirect effects of Job Description and Career Development on Employee Performance. These findings indicate that clarity in job responsibilities and structured career development opportunities enhance employee morale and productivity. Therefore, it is recommended that company management focus on effective task planning and employee potential development to achieve overall organizational performance improvement.

Abstract

The objective of this study was to determine the effect of immersion in different liquid smoke treatments on the specific gravity of Gerunggang wood at the radial direction. The study was conducted at the Forest Products Technology Laboratory, Faculty of Agriculture, Forestry and Fisheries Palangka Raya University. The parameter observed was the specific gravity of the wood. The experimental method used was a 2x2 factorial completely randomized design (CRD) with two treatments: liquid smoke concentration (0%, 5%) and radial location (near the heart and near the bark), with 10 replications. The results of this study showed that immersion in liquid smoke had a not significant effect (p<0.05) on the specific gravity. The influence of the radial position was significantly different, where the part near the liver was higher than the part near the skin. The interaction between the immersion factor and the radial position had no significant effect.
