Abstract

The increasing demand for chemical intermediates in the national chemical industry highlights the need for domestic production to reduce reliance on imports, particularly for strategic products such as methyl chloride. This study presents a preliminary design of a methyl chloride chemical plant with a production capacity of 45,000 tons per year using methanol and hydrogen chloride as raw materials through a catalytic gas-phase synthesis process. The analysis includes mass and energy balance calculations, determination of major equipment specifications, and evaluation of process utility requirements. Furthermore, Pinch Technology Analysis is applied to optimize energy integration within the process by designing an efficient Heat Exchanger Network (HEN). The results indicate that the proposed process is technically feasible and capable of meeting product specifications while significantly reducing external utility consumption through effective internal heat recovery. The integration of preliminary plant design and Pinch Analysis demonstrates strong potential for improving energy efficiency and lowering operational costs, providing a solid basis for further detailed engineering and economic evaluation.

Abstract

Kegiatan Pengabdian kepada Masyarakat ini bertujuan untuk merancang dan mengimplementasikan website profil sekolah sebagai sarana informasi dan promosi di SD Negeri Waru 01. Permasalahan utama yang dihadapi mitra adalah keterbatasan media penyampaian informasi yang masih dilakukan secara manual sehingga kurang efektif dan memiliki jangkauan terbatas. Metode pelaksanaan kegiatan meliputi sosialisasi, pelatihan, dan pendampingan pengelolaan website kepada guru dan staf sekolah. Hasil kegiatan menunjukkan bahwa website profil sekolah berhasil dikembangkan sesuai kebutuhan mitra dan dapat digunakan sebagai media informasi yang mudah diakses oleh masyarakat. Selain itu, pihak sekolah memperoleh peningkatan pemahaman dan keterampilan dalam mengelola serta memperbarui konten website secara mandiri. Keberadaan website ini diharapkan dapat meningkatkan kualitas layanan informasi, mendukung kegiatan promosi sekolah, serta mendorong pemanfaatan teknologi informasi secara berkelanjutan di lingkungan sekolah dasar.
