Abstract

Litter decomposition rate is useful method to determine forest fertility level. The aims of this study were to measure decomposition rate, and analyze the nutrient content released organic carbon, nitrogen, and phosphor from Avicennia marina and Rhizophora apiculata litters during the decomposition process. The research was conducted in the Pulau Dua Nature Reserve, Serang-Banten on A. marina and R. apiculata forest communities. Litter decomposition rate measurements performed in the field. Litter that has been obtained with the trap system is inserted into litter bag and than tied to the roots or trees to avoid drifting sea water. Litter decomposition rate was measured every 15 days and is accompanied by analysis of the content of organic C , total N and P. Our research results showed decomposition rate of A. marina (k= 0.83) was higher than that of R. apiculata (k= 0.41). Differences of  leaf anatomical structure and sea water salinity  influenced to the rate of litter decomposition. Organic C released was declined with longer of litter decomposition, on the contrary of releasing N and P nutrients.

Abstract

Produktivitas adalah metode yang berguna untuk menentukan tingkat kesuburan hutan. Tujuan dari penelitian ini adalah untuk mengukur produktivitas serasah daun Avicennia marina dan Rhizophora apiculata di Cagar Alam Pulau Dua Banten. Penelitian dilakukan di Cagar Alam Pulau Dua Banten pada komunitas A. marina dan R. apiculata. Data lapangan komposisi jenis menggunakan metode jalur berpetak, dan produktivitas serasah menggunakan metode Litter layer. Analisis data komposisi jenis dilakukan dengan memasang petak-petak contoh berukuran 10 x 10 m untuk risalah pohon, 5 x 5 m pancang dan 2 x 2 m untuk semai, sedangkan pengamatan produktivitas serasah dilakukan dengan memasang petak permanen pada masing-masing Komunitas berukuran 50 x 50 m. Hasil Penelitian menunjukkan bahwa A. marina Adalah jenis dominan pada komunitas Avicennia dengan INP pohon 300%, sedangkan R. apiculata Adalah jenis dominan pada komunitas Rhizophora dengan INP pohon 77,83%. Produktivitas serasah pada komunitas A. marina dan R. apiculata yaitu 6.86 ton ha-1-yr 1 dan 7.81 ton ha-1 tahun-1. Faktor-faktor yang mempengaruhi produktivitas serasah yaitu kerapatan pohon dan curah

Abstract

Green Stinkbug (Nezara viridula L.) in English is called "green stink bug". This insect can emit a distinctive and strong odor like Leptocorisa sp. The population density of N. viridula fluctuated greatly throughout the growing season. N. viridula is a pest that can attack more than 200 plants. Therefore, this research aims to find out the latest information regarding the biology and population density of N. viridula L. (Hemiptera: Pentatomidae). The research was conducted in three observation locations. N. viridula breeding was carried out at the Basic Sciences Laboratory, Faculty of Agricultural Technology, Satu Nusa Lampung University. N. viridula breeding is carried out until the N.viridula’s life cycle is reached. Observation of N. viridula using a stereo microscope and Leica LAS EZ software. As the life cycle of N. viridula increases, the stronger it is to defend its life. The imago of N. viridula has a quite long life span, namely around 20 - 60 days. The highest population density of N. viridula was in the generative phase.
