Abstract

This research was aimed to study ethnobotany and the diversity of Pandanaceae that utilized by the people of Orang Rimba tribe who lives in Bukit Duabelas National Park, Jambi. The results of this study showed there were six species of two genera (Benstonea and Pandanus)that were used for habitual and religion activities of those tribes. Only four species were used for crafts, especially mat and wallets (sumpit):Pandanus furcatus Roxb.; Pandanus labyrinthicus Kurz ex Miq.; Pandanus immersus Ridl.; and Benstonea atrocarpa (Griff.) Callm. & Buerki. Two species were used as a ceremony?s complement materials and tribe?s rituals: Pandanus labyrinthicus Kurz ex Miq. (ritual of marriage), and Benstonea atrocarpa (Griff.) Callm. & Buerki to kiding (the procession before the rice planting season begins).Only one species that was used as a material for the house?s or cottage?s roof, Benstonea kurzii (Merr.) Callm. & Buerki. Leaves were the part of the plant which used for the Orang Rimba daily needs.The skill for making handicraft were obtained iterally from generations. The population of pandan assumed to be decreased without effort for the cultivation and conservation.

Abstract

The flowering phenology and floral behavior of Scutellaria discolor and S. slametensis were investigated. S. discolor is distributed over a wider range of habitats but S. slametensis is distributed over a restricted area on Mt. Slamet. Observations of flowering phenology and floral behavior were almost the same and pollination of cleistogamous flowers did not occur in both species.Based on our observations on floral and pollinator behavior, we consider both S. discolor and S.slametensis to have chasmo- and cleistogamous flowers.

Abstract

The selection of planktons as live feed for milkfish larvae is a vital tool to meet the natural character as herbivorous species and to fulfill the needs for nutritious food for fish larval growth and survival. Phytoplankton Nannochloropsis sp. and zooplankton rotifer (Brachionus sp.) were two-selected plankton used as the main food source for the milkfish larvae. We performed this study in two times larval culture batch with four observations of tanks as replication. The results showed that we nourished both targeted planktons as larval food, regarding the positive impacts on larval growth (12±1,37 mm of total length, 7±4.89 mg of body weight) and a high survival rate (65.93?77.70%) achieved at the end of the culture period. Plankton diversity analysis presented that Class of rotifer (Monogononta) and Nannochloropsis sp. (Eustigmatophyceae) were both counted as the most dominant plankton group found in the rearing media, showing a decent sign of food supply for fish in rearing water column. The total number of planktons was high and had the tendency to follow the concentration of selected planktons over the culture period in the controlled water.

Abstract

Dari hasil penelitiannya mengenai marga Dolichos L. dan kerabatnya dari Aftika timur. Verdcourt (1970b) telah memisahkan Dolichos lablab L. dan Dolichos uniflorus Lam. dari margaDolichos dan menempatkannya berturut-turut dalam marga Lab-lab Adans. dan Macrotyloma (Wight & Arn.) Verde. Sebagai konsekuensinya D. lahlab diganti namanya menjadi Lablab purpureus (L.) Sweet dan merupakan jenis tipe marga Lablab yang hanya terdiri atas satu jenis, sedang D. uniflorus menjadi Macrotyloma uniflorum (Lam.) Verde, dan merupakan tipe marga Macrotyloma. Pemisahan kedua jenis ini dari marga Dolichos didasarkan terutama pada adanya perbedaan dalam sifat-sifat putik, serbuk sari serta kromosomnya (Tabel 1).

Abstract

The recent studies were carried out in June-July 1994,And aimed at investigating the distribution of the avifauna in eight main habitat types of Siberut Island.These habitat types were primary dipterocarp forests,primary mixed forests,secondary forests, swamp forests,mangroves, and coastal forests.It appeared that the habitat types tended to determine the bird communities living in the habitats,suggesting that the distribution of bird communities is related to the resources available within the habitats.The results indicate that the conservation measures of avifauna in this island would be better focused on the conservation of their habitats.

H. SIMBOLON & SUKENDAR. 1987. Vegetation and soil conditions of forest in Lelofui, Mount Mutis, Soe, East Nusa Tenggara. Suppl. Berita Biologi 3 : 6 - 10.Research on vegetation and soil conditions of forest in Lelofui, Mount Mutis, Soe East Nusa Tenggara has been done. The density of trees were 358 per nectar; height of canopies ranged between 25 m and 35 m with Eucalyptus urophylla as a dominance species.The relative basal area of E. urophylla was 72,82% which was greater than total basal area of remaining species.The others important species were Podocarpus imbricates, Ilex odorata and Acer niveum.The density of saplings were 708 per hectar.The dominant species of this sapling was Daphniphyllum laurinum with the relative basal area of 69,93% The height of sapling species were less then 10 m. The other important species of saplings were Scutellaria discolor and Acer niveum.The plot consisted of 17 species of trees and 9 species of saplings.This species composition was very small comparing to other tropical rain forests elsewhere.This small number of species composition is suggested not directly correlated with a soil fertility.Soil analisis form the plot showed that its properties was not so distinct from other tropical rain forest soil conditions.

Abstract

In dry land areas such as Nusa Tenggara Timur (NTT), low production of maize may due to selection of using local varieties that are mostly drought tolerant.One of the local varieties known as Pena Tunu? Ana? have been harversted in very early age of 1.5 month, hence it was categorised as very early mature maize. This variety is therefore play an important role in the food security system for people in NTT as they can be harvested earlier than other varieties. However, no information has yet on how this variety response to drought stress. Drought stress is one of the factors causing the decline in maize production. This study was conducted at experimental house in Cibinong Science Centre (CSC) to evaluate responses of Pena Tunu? Ana? against drought stress treatment. The experiment was done in six degree of drought treatments, 0 (control), 4, 8, 12, 16 and 20 days with 4 replications. Parameters measured were soil water, relative leaf water,proline and sugar content in leaves and roots at each level of drought stressed. Results showed that with increasing level of drought stress,soil water and relative leaf water content were decreased while proline and sugar content were increased. At the same level of drought stress, accumulation of proline and sugar in the roots was higher than those in the leaves. Drought stress terminated at 16 days, where the roots content of proline reached 10.36 mg/g and sugar 110.91 mg/g, while the leaves content of proline was of 2.84 mg/g and sugar was of 38.44 mg/g. At the level of drought stress during 16 days, the plants suffered temporary wilting but refreshed after watering.

E. PURWANINGSIH & I. BUDIARTI. 1986. Rearing Stomoxys calcitrans (Diptera : Muscidae) in the laboratory. Berita Biologi 3(5): 240 - 243. The stable fly 5. calcitrans was reared in the laboratory in an attempt to the study the biology. Flies captured from the field were used as parent stock. Eggs were laid within 4 days after captured. The total number of eggs deposited were 48 (15-96) with an incubation period of 1,6 (1-3) days. The larval and pupal period were 4,9 (8-23) days and 6,4 (1-3) days respectively. Hatching of eggs reach 26,1 (21,4-31,1) %. Adult emergence reach 86 %. Feeding activities was recorded for the adult as well as larvae. Flies could survive for 2-32 days in the laboratory without any sign of being able to produce offspring. Behaviour and the morphology of each development stage were discussed.

Abstract

Ragi tapai biasa disebut juga ragi pasar karena mudah dibeli di pasar. Pembuatannya biasanya dilakukan tidak secara steril, menggunakan peralatan sederhana, serta memakai tepung beras sebagai bahan dasar utama dan beberapa macam rempah-rempah sebagai bahan dasar tambahan.Bahan dasar utama berfungsi sebagai bahan pembawa (carrier) jasad renik yang diperlukan kehadirannya, sedangkan bahan dasar tambahan kemungkinan berfungsi sebagai pencegah kehadiran jasad renik yang tidak dikehendaki (Saono et al. 1974; Saono 1982).Karena dalam pembuatan ragi tapai biasanya tidak digunakan biang (starter), maka sumber utama jasad renik adalah lingkungan tempat pembuatannya dan bahan-bahan dasar yang digunakan
