Abstract

PT X is an industry engaged in the production of snacks. The processes and activities in the industry produce by-products, namely hazardous and toxic waste. All waste is stored in temporary storage, but based on observations, the extant temporary storage does not meet the government's requirements. Accordingly, PT X redesigned a temporary storage area following government requirements. This study aims to identify a temporary storage location that complies with government regulations for PT X. Recording the types, characteristics, and quantities produced by PT X, followed by existing observation, is followed by the calculation of facility needs according to SNI and individual calculations. This research analysis provides property and layout recommendations to enhance the condition of PT X's temporary storage for hazardous and toxic refuse.

Abstract

Kawasan konservasi pada lanskap infrastruktur energi memiliki fungsi penting sebagai habitat vegetasi dan ruang penyangga ekologis, sehingga kondisi keanekaragaman dan struktur komunitas tumbuhan perlu dievaluasi secara periodik. Penelitian ini bertujuan menganalisis struktur komunitas dan keanekaragaman vegetasi pada kawasan konservasi hutan Main Transformer (MTR) PT PLN Nusantara Power UP Cirata. Pengambilan data dilakukan pada 30 plot utama berukuran 20 × 20 m yang tersebar pada empat blok, dengan desain petak bersarang untuk strata semai, pancang, tiang, dan pohon. Analisis meliputi frekuensi relatif, kerapatan relatif, dominansi relatif, Indeks Nilai Penting (INP), serta indeks keanekaragaman Shannon-Wiener (H'). Hasil menunjukkan bahwa Musa paradisiaca memiliki INP tertinggi pada strata semai (24,68%), pancang (90,24%), dan tiang (67,32%), sedangkan Tectona grandis mendominasi strata pohon dengan INP 36,50%, diikuti Swietenia macrophylla (29,66%) dan Samanea saman (25,98%). Nilai H' masing-masing strata semai, pancang, tiang, dan pohon adalah 2,98; 2,08; 2,87; dan 2,98, yang seluruhnya menunjukkan tingkat keanekaragaman sedang berdasarkan klasifikasi yang digunakan dalam penelitian. Rendahnya nilai pada strata pancang menunjukkan dominansi lebih kuat pada fase regenerasi tertentu. Hasil ini menegaskan perlunya pengelolaan vegetasi yang menjaga regenerasi alami, mempertahankan struktur berlapis, dan meningkatkan keragaman jenis pada strata yang lebih terdominasi.Kata kunci: cirata, indeks nilai penting, kawasan konservasi, keanekaragaman hayati, vegetasi
