Abstract

The purpose of the author's observation were to the system and licensing process of foreign ship crew at PT. Pelayaran Batam Samudra. The type of observations used by the author are qualitative and descriptive. In broad terms, the system and procedures for the licensing of foreign ship crews begin with the first step, which is the manufacture of a dahsuskim as a basis for employing foreigners as ship crew operating in the waters of Indonesia. After the completion of the 'dahsuskim,' the next step is the process of creating the COR. The COR, serves as recognition of the skills and qualifications of the foreign ship crew. The next process is the issuance of the IMTA. which is required as an official permit to employ foreign workers. Subsequently, when foreign ship crew members intend to leave Indonesian territory due to the expiration of their contracts, the next process is the handling of EPO  to facilitate their departure from Indonesia. Challenges faced by the authors in the licensing process include a lengthy licensing processing time, document discrepancies, lack of coordination, and limited human resources, which can result in obstacles in the licensing process. To address these issues, it is essential to improve coordination between agents and ship owners, conduct regular checks on licensing requests, and increase the number of agents to facilitate the licensing process for the foreign ship crew.

Abstract

 Pengamatan dilakukan terhadap tujuh log sejak tahap pemotongan log, pembuatan dolok, pengulitan, hingga pengupasan dengan mesin rotary lathe konvensional bercakram. Volume log, dolok, finir kontinu, finir potong, dan poli-poli diukur menggunakan pendekatan input-output. Data rendemen dianalisis secara deskriptif dan dibandingkan antarjenis kayu menggunakan ANOVA satu arah. Rendemen total rata-rata masing-masing sebesar 64,08% untuk meranti merah, 77,21% untuk keruing, dan 62,85% untuk tengkawang. Meskipun keruing menunjukkan rendemen tertinggi, perbedaan antarjenis tidak nyata secara statistik (F = 0,447; p = 0,668), terutama karena jumlah sampel terbatas dan variasi antarlog yang tinggi. Limbah yang teridentifikasi meliputi lempengan log, kulit kayu, serbuk gergaji, poli-poli, finir sobek, dan empulur. Berdasarkan bentuk dan mutunya, limbah tersebut berpeluang dimanfaatkan secara bertingkat sebagai finir inti, komponen papan blok atau kemasan, bahan baku panel partikel dan serat, pelet, biochar, karbon aktif, produk berbasis tanin, serta bahan bakar boiler. Sortasi log, ketepatan penentuan titik pusat kupasan, pengendalian pisau dan nose bar, serta pemilahan limbah secara sistematis direkomendasikan untuk meningkatkan rendemen dan mendukung bioekonomi sirkular berbasis kayu.
