AbstractUnderstorey plant is a part of forest having important ecological functionsin the forest ecosystem and the potential for human use is as a source of food,shelter, and medicine. The existence of the plant is often overlooked that HKMSdoes not have data on understorey plant. The study aims to analyze thecommunity structure as well as the potential use of understorey plant in HKMSKota Jambi. The data was collected from January 2012 to February 2012 with thequadrate transect method in 100 sample plots (1 m x 1 m) were systematically.Found as many as 45 families comprising 83 species and 3674 individuals. HighImportance Value obtained by herbaceous species Pennisetum purpureum(71,81%). The highest density at plot 61 (209 individuals). The species with thehighest frequency is Melastoma malabathricum (37%). There are five speciesforming association. Life form are the largest tree seedlings (39 species). Speciesdiversity index of 2.49. The native species of Indonesia composition in ZonaPemanfaatan Sedang (ZPS) is higher than in Zona Pemanfaatan Rendah (ZPR).The results of interviews to the people around HKMS, most plants use is formedicinal (53 species), secondary food (23 species), building materials andhousehold appliances (18 species), firewood (15 species), ornamental plants (10species), and craft (7 species). The highest Index of Cultural Significance (ICS)value derived species Tamarindus indica (50) with three using categories, namelythe use of additional food, medicine materials and firewood."

"ABSTRAKPenelitian mengenai komunitas epifit telah dilakukan pada cuplikan seluas satu ha di Hutan Kota Muhammad Sabki (HKMS), Kota Jambi. Data diambil pada bulan Januari sampai Februari 2012. Jumlah seluruh pohon 489 individu, 25 individu yang terdiri atas 10 spesies menjadi inang epifit. Pohon inang yang paling banyak dijumpai adalah Hevea brasilliensis, ada 6 individu. Permukaan kulit Hevea brasiliensis memiliki karakteristik yang kasar dan banyak lekukan atau celah, banyak ditumbuhi epifit dengan jumlah 5 spesies. Epifit yang ditemukan terdiri atas Orchidaceae dan 4 suku tumbuhan paku-pakuan (Polypodiaceae, Aspleniaceae, Nephrolepidaceae dan Davalliaceae). Pyrrosia angustata, Microsorum superficiale, Lecanopteris sinuosa dan Drynaria sparsisora.merupakan spesies yang tercatat dari Polypodiaceae. Sementara itu suku lainnya hanya terdiri atas 1 spesies yaitu Aspleniaceae (Asplenium nidus), Nephrolepidaceae (Nephrolepis biserrata), Davalliaceae (Davallia divaricata) dan Orchidaceae (Dendrobium crumenatum). Spesies yang paling banyak tersebar pada petak pengamatan adalah Asplenium nidus, Pyrrosia angustata, Nephrolepis biserrata, Leconopteris sinuosa, Drynaria sparsisora, Dendrobium crumenatum dan Davallia divaricata. Selain terdapat di 7 petak pengamatan, Asplenium nidus juga menempati 7 spesies spesies pohon inang. Epifit yang memiliki Nilai Unggulan tertinggi adalah Lecanopteris sinuosa. Lima spesies epifit masing-masing terdapat di pangkal batang dan batang, dan empat spesies tercatat pada tajuk pohon.

AbstractResearch on the epiphytic community was performed on a one-hectare sample in Hutan Kota Muhammad Sabki (HKMS), Kota Jambi. The data were collected on January to February 2012. A total of 489 individual trees was recorded, of which 25 individuals of 10 species were hosts of the epiphytes. The most common host tree was rubber tree, Hevea brasilliensis, totalling 6 individuals. The barks of Hevea brasiliensis trees have rough surfaces with many loopholes, overgrown by epiphytes totalling 5 species. The epiphytes recorded consist of Orchidaceae and four fern families (Polypodiaceae, Aspleniaceae, Nephrolepidaceae and Davalliaceae). Pyrrosia angustata, Microsorum superficiale, Lecanopteris sinuosa and Drynaria sparsisora are the species of Polypodiaceae recorded. Meanwhile, the other families each consists of only one species, i.e., Aspleniaceae (Asplenium nidus), Nephrolepidaceae (Nephrolepis biserrata), Davalliaceae (Davallia divaricata) and Orchidaceae (Dendrobium crumenatum). The species that are distributed in most quadrats are Asplenium nidus, Pyrrosia angustata, Nephrolepis biserrata, Leconopteris sinuosa, Drynaria sparsisora, Dendrobium crumenatum and Davallia divaricata. In addition to its occurrence in seven quadrats, Asplenium nidus inhabited also seven of the ten host-tree species. The epiphyte having the highest Prevalence Value was Lecopteris sinuosa. Five species of epiphytes, respectively, occurred on the bases of trees and tree, and only four species was recorded in the tree crowns."

"This study was designed to examine the structure and tioristic composition a lowlandrainforest on the southern slope of Cyclops Mountains, Jayapura. at 300-500 m above sea level.Plants were sampled in 6 plots of 40 m x 40 m each and 1 plot of 20 m x 20 m. The studyrecorded 130 tree species (DBH equel or bigger than 10 cm at dbh) belonging to 39 families, withdensity of 743 treeslha and total basal area 1993.62 mz. Anisoptera thurffera dan Mallolusechinatus are the leading species. The bigest diameter reoorded was 95 cm (Anisoptera thunifera)and the tallest tree reach 50 m (Anisoptera thur.'ra, Hopea iriana and Syzygiumleptoraphleboides). Tree species richness is similar to other forests in the north of Papua(Mamberamo) and north of the Cyclops Mountains. Regeneration was very poor. There is anindication that the forest sampled was at one time disturbed."

"The books offers a comprehensive and current review on social issues related to forests that other, more specialized publications, lack. It is also theory-rich, offering both mainstream and critical perspectives, and presents up-to-date empirical materials. Reviewing these four major research themes, the main conclusion of the book is that naïve optimism associated with forest-people interfaces should be tempered. The chapters show that economic development, political empowerment and environmental aims are not easily integrated. Hence local landscapes and communities are not as 'makeable' as is often assumed. Events that take place on other scales might intervene, local communities might not implement policies locally, and governance practices might empower governments more than communities. This all shows that we should go beyond community-based ideas and ideals, and look at practices on the ground. "

"Program pengelolaan hutan bersama masyarakat (PHBM) dibentuk oleh perhutani untuk lebih melibatkan masyarakat dalam mengelola hutan di Pulau Jawa. Partisipasi aktif dalam program ini menjadi kunci utama keberhasilan program PHBM. Tulisan ini menganalisis pengaruh karakteristik petani hutan terhadap tingkat partisipasinya dalam program PHBM yang berlokasi di Desa Buniwangi, Kecamatan Pelabuhanratu, Kabupaten Sukabumi. Riset menggunakan metode kuantitatif dengan analisis regresi dan deskriptif. Sebagian besar petani hutan berpartisipasi dalam rapat perencanaan PHBM, pelaksanaan dan evaluasi PHBM. Umur petani hutan berpengaruh signifikan terhadap partisipasi petani hutan dalam perencanaan dan evaluasi program PHBM."

"Penelitian dilakukan pada Formasi Cimapag di pantai Tanjung Layar, Kabupaten Lebak, Banten. Penelitian kali ini bertujuan untuk mengetahui kondisi geologi struktur pada daerah pantai Tanjung Layar, Kabupaten Lebak, Banten. analisis yang dilakukan merupakan analisis yang berfokus pada objek struktur geologi yang berada pada permukaan daerah penelitian. Metode yang digunakan adalah pemetaan lapangan dan juga analisis dengan metode fry yang diharapkan dapat menjawab kondisi tektonik pada daerah penelitian. Pada daerah penelitian disimpulkan terdapat pola perlipatan dengan ditemukannya deformasi dalam bentuk kompaksi akibat dari regangan murni. Deformasi kompaksi telah mengurangi volume dari singkapan Formasi Cimapag sebesar 56.8 %.

The research was conducted in the Cimapag Formation on the coast of Tanjung Layar, Lebak Regency, Banten. This research aims to determine the geological conditions of the structure in the coastal area of Tanjung Layar, Lebak Regency, Banten. The analysis carried out is an analysis that focuses on the geological structure objects that are on the surface of the research area. The method used is field mapping and analysis with themethod fry which is expected to answer the tectonic conditions in the research area. In the research area, it was concluded that there was a folding pattern with the discovery of deformation in the form of compacting due to pure strain. The compacting deformation has reduced the volume of the outcrop of the Cimapag Formation by 56.8%."
