    Abstract
    Sri Susanti Ningsih, Inventory of mangrove as the management efforts of the coastal region of Deli Serdang regency, under the academic supervision of Dr. Retno Widhiastuti, MS as the chief, Dr. Budi Utomo, SP, MP, and Ir. Guslim, MS, as the members. The research aims describe and compare the condition and management of the mangroves at Deli Serdang regency. The research aims describe and compare the condition and management of the mangroves at Deli Serdang regency. The research study was conducted in 9 mangrove villages at the coastal region of Deli Serdang regency. The methods used the square line with a line 10 m x 60 m sizes by vertical sea side ways for each village. The seedlings sub size 2 m x 2 m square, the saplings sub size 5 m x 5 m square, and trees level sub sizes 10 m x 10 m. The parameter analysis was important values index, diversities index, profile diagram, the mangrove thickness and salinities. The result, shows that mangrove vegetations was dominated by Avicennia marina (api-api hitam) and followed by Excoecaria agallocha (buta- buta) and Avicennia alba (api-api putih). The diversities mangroves of the coastal region Deli Serdang regency are still low. The thickness and the thinness of mangrove forest were found in Paluh Kurau (500 m) and Rugemuk (20 m), respectively. The mangroves villages with the highest canopy wide were in Karang Gading (78,99%), Tanjung Rejo (63,76%), while the lowest one were in Paluh Sibaji (20,58%) and Rugemuk (26,43%). The highest salinity were found at sub districts of Labuhan Deli and Hamparan Perak, while middle salinity at sub district of Percut Sei Tuan, while of district of Pantai Labu the salinity were from low level to middle. Base on the analysis of the vegetation closeness and canopy width, the condition of coastal region of Deli Serdang regency mangroves were destroyed.
     
    Sri Susanti ningsih, Inventarisasi Hutan Mangrove Sebagai Upaya Pengelolaan Wilayah Pesisir Kabupaten Deli Serdang, dibawah bimbingan Dr. Retno Widhiastuti, MS selaku ketua, Dr. Budi Utomo, SP, MP dan Ir. Guslim, MS, masing- masing sebagai anggota. Penelitian ini bertujuan untuk mendiskripsikan dan membandingkan kondisi hutan mangrove serta cara pengelolaan hutan mangrove yang ada di Kabupaten Deli Serdang. Sebagai bahan kajian penelitian adalah 9 desa hutan mangrove di wilayah pesisir Kabupaten Deli Serdang.Metoda penelitian yang digunakan adalah metoda garis berpetak (jalur berpetak) dengan satu buah jalur untuk tiap desa penelitian dengan ukuran 10 m x 60 m dengan arah tegak lurus tepi laut. Untuk tingkat semai ukuran sub petak 2 m x 2 m, untuk tingkat pancang ukuran sub petak 5 m x 5 m dan untuk tingkat pohon ukuran sub petak 10 m x 10 m. Parameter yang dianalisis antara lain indeks nilai penting, indeks keanekaragaman, diagram profil, ketebalan mangrove dan salinitas.Hasil penelitian menunjukkan bahwa jenis vegetasi mangrove yang mendominasi wilayah pesisir kabupaten Deli Serdang adalah Avicennia marina (api-api hitam) diikuti dengan Excoecaria agallocha (buta-buta) dan Avicennia Alba (api-api putih). Keanekaragaman jenis mangrove yang terdapat di wilayah pesisir Kabupaten Deli Serdang tergolong rendah. Ketebalan hutan mangrove yang cukup tebal terdapat di Desa Paluh Kurau (500 m). Sedangkan ketebalan hutan mangrove yang tipis terdapat di Desa Rugemuk (20 m). Desa mangrove yang luas penutupan tajuknya tertinggi adalah Desa Karang Gading (78,99%), Desa Tanjung Rejo (63,76%), sedangkan desa yang luas penutupan tajuknya terendah adalah Desa Paluh Sibaji (20,58%) dan Desa Rugemuk (26,43%). Salinitas tertinggi dijumpai di Kecamatan Labuhan Deli dan Kecamatan Hamparan Perak, tetapi di Kecamatan Percut Sei Tuan salinitas sedang dan di Kecamatan Pantai Labu dari rendah sampai sedang. Berdasarkan hasil analisis kerapatan vegetasi dan luas penutupan tajuk bahwa kondisi hutan mangrove di wilayah pesisir Kabupaten Deli Serdang umumnya rusak.
