Abstract

The aim of this study is to obtain basic descriptive account of structure and floristic composition of cacao based agroforestry in conserving tree species diversity in West Sumatera. An analysis of the composition and structure of three types of cacao based agroforestry system (AFS) [cacao - rubber (CR), cacao ? coconut (CC) and cacao multistrata (CM)] was conducted in April to June 2017. Data collection was done by using quadrat method of 20 x 20 meter plots with a total of 6 plots on each types of AFS. Herbarium specimens were collected and identified. Among all types of these AFS, CC was the most diverse floristically (H? = 1.02) with the highest total of species (10 species), followed by CM (9 species) and CR (7 species). CM has the highest tree density of 1108 trees per ha and the highest total of basal area (30.53 m2). We also did a comparison of the floristic composition of cacao based AFS with the nearest natural forest from previous study. There was a large decrease in the number of non-cocoa tree species from natural forest to AFS, from 139 to 6-9 species. The only native tree species found both in the forest and AFS is Pterospermum javanicum Jungh. It is concluded that three types of cocoa based AFS in West Sumatera were floristically different with natural forest.

Abstract

Lalat buah Bactrocera carambolae (Drew & Hancock) dan Bactrocera dorsalis (Drew & Hancock) dilaporkan dapat hidup dan berkembang pada berbagai jenis buah-buahan sehingga menimbulkan kerusakan pada buah yang sekaligus menimbulkan kerugian secara ekonomi. Penelitian ini bertujuan untuk mempelajari preferensi dan perkembangan B. carambolae dan B. dorsalis pada beberapa jenis buah dan untuk mendapatkan informasi jenis buah yang paling disukai lalat buah. Penelitian dilakukan di Laboratorium Entomologi dan Laboratorium Koleksi Spesimen Serangga, Balai Besar Penelitian dan Pengembangan Bioteknologi dan Sumber Daya Genetik Pertanian Bogor, pada bulan Juni 2011 sampai Maret 2012. Perlakuan buah terdiri belimbing malaya (Averrhoa carambolae), mangga varietas manalagi (Mangifera indica), jambu biji getas merah (Psidium guajava), jambu air varietas citra (Eugenia aquae), jambu bol jamaika (Eugenia malaccenensis), dan pepaya california (Carica papaya). Hasil penelitian menunjukkan bahwa lalat buah B. carambolae paling tertarik pada buah belimbing malaya dan manggga manalagi dan B. dorsalis pada buah pepaya california dan mangga manalagi.

Abstract

Two new species of Endiandra (Lauraceae), i.e. Endiandra areolata Arifiani and Endiandra lanata Arifiani are described from New Guinea. Both species have staminal glands, but their form is different in the two species.  Moreover, E. areolata Arifiani is characterized by its prominent areolation formed by the minor venation, and E. lanata Arifiani is easily recognized by the presence of a dense curly indument on its twig, leaves, inflorescences and flowers.

Abstract

Flood events are often inundated rice fields and can cause flooding to surrounding areas (the lower reaches of the river) should not be underestimated (just blame the rainfall factor alone), but should be seen also internal factors of the techniques of rice cultivation in paddy fields. The purpose of research/study was to analyze the effect of flooding on the cultivation of paddy rice to infiltration and provide alternative solutions cultivation techniques to reduce flooding. The research method in this study is a survey method with the quantitative approach. Techniques flooding in paddy rice cultivation, especially irrigated cropping pattern rice 3 times a year have resulted in the formation of plow layer tread that is waterproof (hardpan). Waterproof coating that forms on the floor of paddy (rice surface) cannot infiltrate rainwater so that if there is a high-intensity rainfall in the rainy season, rice cannot hold the rain water will overflow and cause flooding to the area around the rice fields. Techniques inundation in lowland rice cultivation resulted in flooded paddy rice growth period in a rather long time (over 2 months), so that the aggregate soil is loose and prone to erosion and landslide potential. Anticipation of floods caused by wetland can be done by making the high rice fields higher than the height of the floodwaters that ever happened to the rice field and lowering the height of standing water in the paddy fields.

Abstract

Mangrove litters as a source of nutrients for sylvofishery pond (TS), sedimented pond (TT), and conservation pond (TP) was studied at Blanakan mangrove pond during April until June 2008. The variables of study were litter production, litter decomposition, and dissolved nutrients (ammonium, nitrite, nitrate, and phosphate). The obtained data were analyzed using F test and continued using Least Significant Different (LSD). The results showed that litter production at TS, TT, and TP were 19.55±4.34 ton/ha/year, 15.90±1.98 ton/ha/year, and 21.67±1.89 ton/ha/year respectively. The decomposition rate at TS, TT, and TP was 0.051±0.038, 0.051±0.018, and 0.081±0.041, respectively. Mangrove litters were potentially as a source of dissolved nutrients at Blanakan mangrove pond. Increasing both litter production and decomposition rate could increase ammonium, nitrite, and phosphate. Therefore, mangrove litters were play role for determined the fertility at Blanakan mangrove pond.

Abstract

Endiandra species from New Guinea consist of species which vary in vegetative and reproductive characters. Staminal glands are present in 34 species out of 46 species of Endiandra in New Guinea, in constrast to the Bornean and Malay Peninsular species that lack of staminal glands. Beilschmiedia is a genus that often confused with Endiandra vegetatively, only flower characters can differentiate the two genera. This study was aimed to understand relationships of Endiandra species in New Guinea and to know the importance of staminal glands in grouping the New Guinean species of Endiandra. The relationships between Endiandra and Beilschmiedia based on the morphological characters will also be discussed. A phylogenetic analysis was performed to 47 morphological characters from 50 taxa, consisted of 41 species of Endiandra and 6 species of Beilschmiedia (as in-groups) with 3 species of Cryptocarya (as outgroups). Phylogenetic tree was constructed using Maximum Parsimony method. Phylogenetic tree showed that 47 in-groups taxa were grouped into five clades however with low bootstrap support. The species with and without glands are not separated from each other. Therefore, because of low bootstrap support, the monophyly of Endiandra and Beilschmiedia and the importance of staminal glands cannot be confirmed.
