Abstract

Hexanchus spp. are shark species that are often caught in the Indian Ocean southern Nusa Tenggara and its status is Near Threatened, but the information is still relatively limited. This study aimed to sex ratio, length-weight relationship and reproductive size of sixgill shark, Hexanchus spp. caught from southern Nusa Tenggara waters. This study had been carried out during 2016 at the Fishing Port of Tanjung Luar, East Lombok, West Nusa Tenggara. Shark data collection was done by measuring the length, weight, maturity and fishing data. Data were analyzed  by formula of sex ratio, length-weight relationship, length at first maturity (Lm) and length at first catch (Lc). The results showed that Hexanchus spp. caught in the southern Nusa Tenggara waters consisted of H. nakamurai (81.82%) and H. griseus (18.18%). The sex ratio of both sharks was dominated by the female. The average of the total length of H. griseus (218.3 ± 96.08 cm). It was longer than H. nakamurai (127.6 ± 30.35 cm). The length-weight relationship of H. griseus was formulated as W = 0.0195 LT 2,6344 (R² = 0,9265) and H. nakamurai with the formula W = 0.002 LT 3,1098 (R² = 0.902). Both species  have the size of Lm was bigger than the size of Lc which indicated  to their population vulnerability.

Abstract

Wetlands in Peatland Development Area has potential for the development of paddy, vegetables and palawija. Development of the commodities are limited or restricted by many limiting production factors such as nutrients, water and plant varieties. The purpose of this study is to know the influence of amelioration and fertilization packages on the growth and yield of peanuts in the swampland peat land development area. The treatments consisted of four amelioration and fertilization package i.e.: (1) Farmer’s package I: 250 kg.ha dolomite, (2) -1 -1 -1 -1 Farmer’s package II: 2.5 t.ha straw compost+18 kg.ha P2O5+300 kg.ha fly ash, (3) Recommendation package: 1.0 t.ha dolomite+22.5 -1 -1 -1 -1 -1 -1 kg.ha N + 36 kg.ha P2O5, and (4) Research package: 2.0 t.ha dolomite+22.5 kg.ha N+22.5 kg.ha P2O5 +30 kg.ha K2O. The result showed that the growth of plants (plant height and number of branches) does not differ between treatments, and the obtained peanut pod yield improvement is 50.45% in the research package treatment compared to Farmer’s package I.

Abstract

An experiment was conducted to evaluate the performance of production traits of the synthetic population of Border Leicester x Merino crossbred. A comparison was made between the F2, F2.5, F3 generations ( synthetic population ) and Fl generation. Estimates the effects of maternal heterosis in the synthetic populations of Border Leicester x Merino crossbred were analyzed by the method of least squares for Birth Weight (BW), Weaning Weight (WW) and Yearling Weight (YW). Two kind of analyses were executed for each traits i.e. within Fl sire generation and within F2 sire generation. For each analysis, maternal heterosis was respectively calculated as twice the difference between the least squares means of F2 and F2.5 lambs and F2.5 and F3 lambs.Pool estimates of maternal heterosis effects were also calculated for each traits. Research results showed that there was no significant difference of BW between F2, F2.5 and F3 generation. Weaning Weight was significantly higher (P < 0,05) in the synthetic population as compared to the Fl generation. Yearling Weight (YW) was significantly higher in the F2 generation as compared to F2.5 and F3 generation at the level of 5% (P < 0,05 ) and the 10% level (P < 0,10 ) respectively. Within Fl sire generation,maternal heterosis effects were 12,65%, 3,4% and 1,67% for Birth Weight (BW), Weaning Weight (WW) and Yearling Weight(YW). From the analysis within F2 sire generation, maternal heterosis effects were 1% for BW, 4,49% for WW and 3,09% for YW.Pool estimates of maternal heterosis effects were 5,78%, 3,95% and 2,37% for BW, WW and YW respectively. These results indicated that the effect of maternal heterosis gradually declined from preweaning to postweaning periods. In general, the present estimates of maternal heterosis for body weights are in close agreement with previous publications.In order to gain maximum benefit from heterosis, these results suggest that in designing a crossbreeding program,especially in developing a new synthetic population, we should take into account not only individual heterosis effects but also all other different sources of heterosis such as maternal heterosis. Genetic methods presented in this paper can be used in the breeding program in Indonesia,especially in the development of the improved synthetic sheep population. However to the determine the superiority of synthetic population over the Fl generation, the overall comparison should be made on body weight, growth rate, survival rate and fertility traits.

Abstract

SIH KAHONO, L.E. PUDJIASTUTI &. M. AMIR. 1987. Insect visitors on Acacia villosa Willd. Suppl. Berita Biologi. 3 : 70 - 71 Insect visitors on Acacia villosa Willd. (Leguminosae) has been observed at 10 flowering plants at Cibinong, Bogor. Observation were made at 6 a.m.-6 p.m. by means of collecting insects that visit the flowers of A. villosa for 30 minute with the interval time collection of 2 hours.There were found Hymenoptera (17 species), and followed by Lepidoptera (7 species) and Diptera (3 species).The community sturcture of the insect visitors at interval of 2 hours are varies, the number increased toward the mid day, and gradually declined in the evening. This fluctuation is probably due to the nectar content during the day.

Abstract

Javasom [Talinum paniculatum Jacq. (Gaertn.] is one of popular vegetable plants with potential medicinal properties.The plant root is often used as a substitute for ginseng (Panax ginseng L.), and the leaves are used as a vegetable and as a substitute for purslane (Portulaca olaraeae L.).An effort to improve genetic quality of the plant was made through induced mutation with ethyl methane sulphonate (EMS).A variety of EMS dosages (0, 0.3%, 0.6%, 0.9%, 1.2%, 1.5% and 1.8%) were applied to javasom seeds to induce mutation for 24 hours at room temperature. A population of the first and second generation after mutagen treatment (M, and M2,respectively) was established and observed at vegetative and generative stages. At M, generation, plant growth was suppressed and plant yield was decreased.Chimeras and chlorophyll mutation were observed in every EMS-treatment level, which was indicated that mutation was induced in the plant. Lethal-dosage (LD-50) of EMS was at 1.2%-1.5%. M, population were recovered and showed variation in all parameters observed. High genetic variation coefficients were found in most of plant characters observed.All parameters have a medium to high heritability, which indicated that all parameter observed were relatively easily inherited.However, all genotypes are subjected to be evaluated in the next generation in their performance stability.

Abstract

Carrot (Daucus carota L.) is generally cultivated at uplands areas. However, for lowlands, technology of innovation related to fertilizing can be considered as the solution. This study was aimed to determine the appropriate fertilizer package, the variety of carrot adapted in rainy season, and sandy clay loam of the lowland areas in Palangka Raya, Central Kalimantan. This study was designed by using a split plot exponential design consisting of main plot consisting of carrot varieties: (V1 = Kirana and V2 = Lokal Batu) and sub-plot, consisting of fertilizer packages (P0 = control, P1 = low. P2 = medium, P3 = High). The results showed that variety of Lokal Batu was more adaptive than Kirana for having higher tuber production. 16.95 g/plant (10.12 t/ha) and 16.33 g/plant (9.80 t/ha). The result showed that the highest production of 18.89 g/plant was obtained in a medium fertilizer package as compared to other fertilizer package. There was no significant interaction between carrot varieties and fertilizer packages. The trend showed that the fertilizer packages of P2 produced the highest yield of total weight of tuber production within each carrot variety of 10.36 ton/ha for Kirana and 12.31 ton/ha for Lokal Batu.

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.
