Abstract

The study of Balanophora in South Sumatra has been carried out from July-August 2018. This research uses the direct observation and collection method in 3 km long track in the Bukit Jambul Gunung Patah Protection Forest Area, South Sumatra. Sample identification was carried out in the Biology Department of the Faculty of Mathematics and Natural Sciences, Sriwijaya University. The results show that there is one Balanophora species, B. elongata. There are 2 subspecies of this species, namely B. elongata var. elongata and B. elongata var. ungeriana (Valeton) B. Hansen. The difference between these 2 subspecies is var. ungeriana in the tubers is not elongated with longitudinally coarse luruk leaves. At that location only found species of B. elongata var. ungeriana. Distribution: Peninsula Malaysia, Borneo, Sumatra, Java, and mostly in West Java for subsp. ungeriana is only recorded on the island of Java precisely at Mount Salak and Mount Gede in West Java. This species is the first record for the Sumatra Island. There are around 30 individual species of B. elongata var. ungeriana respectively 23 female individuals and 7 male individuals. Bulbs, leaf characters and flower types are important to identifying the species of Balanophora. Most of these species are found in habitats where they have a height of 1000-2800 meters above sea level which are suitable for habitat in the Bukit Jambul Gunung Patah Protection Forest Area.

Abstract

Mass propagation technology through somatic embryogenesis has become an alternative for producing sugarcane seedlings rapidly.Application of proper plant growth regulator and concentration contribute to support somatic embryogenesis development. This study applied the combination of liquid and solid culture during proliferation stage to promote cell dispersion of embryogenic callus, rapid  embryo somatic production, and improve regeneration potency of somatic embryo. Application of 2,4-D and coconut water during proliferation may expected as proper combination for accelerating somatic embryo development and regeneration.Development of somatic embryogenesis in sugarcane var. Bululawang during proliferation were described in this study. Embryogenic callusfrom induction media were transferred to proliferation media containing MS Basal + vitamin supplemented with sucrose different level of 2,4-D (1 mgl-1, 2 mgl-1, 3 mgl-1, 4 mgl-1 ) and coconut water (0% and 5%).Result showed that low concentration of 2,4-D induced optimum somatic embryogenesis development in proliferation and regeneration. Concentration of single 2,4-D 1 mgl-1 without coconut water  induced rapid development of scutelar and coleoptilarduring proliferation and resulted in better shoot regeneration. In other way, 4 mgl-1 of 2,4-D concentration  affected to inhibit scutelar and coloeptilar formed as the result of failure callus differentiation.

Abstract

Tissue culture have been used for plant propagation generally, and the medium has been important role in its growth. Vegetative propagation on Phalaenopsis sp orchids can be through the protocorm like bodies (PLB). Medium of affect on propagation of PLB was carried out on medium type, kind of basal medium and concentrations ratio of naphtaleneacetic acid (NAA) and benzylamino purine (BAP). The experiment used Completely Randomized Factorial Design with 3 replications and continued with the Duncan Multiple Range Test (DMRT) if there were significant differences. The results showed that the best callus formed in a combination of solid medium type and Murashige & Skoog (MS) basal medium was 100%. The most number of PLB produced from a combination of liquid medium types and a concentration ratio of NAA 1 mgL-1 and BAP 5 mgL-1, the most number of plantlet produced from a combination of MS basal medium and the concentrations ratio of NAA 0.1 mgL-1 and BAP 0.1 mgL-1, the number of PLB germination and PLB with leaves were influenced by each single factor.

Abstract

Non-tidal swamp is one of suboptimal land available to increase rice production in Indonesia. The problems is stagnant flooding during vegetative growth phase of the crop. Therefore, it is important to have rice varieties that tolerant flooding. Crossing and selection have been conducted to obtaine BC2F2 genotype from local swamp rice varieties, i.e. Siam, Pegagan and Pelita Rampak. This research was aimed at knowing the growth and production of several genotypes BC2F2 and their parental varieties, Siam, Pegagan and Pelita Rampak. The research was conducted in non-tidal swamp in Village Sako, sub-district Rambutan, District Banyuasin, South Sumatra from October 2017 to March 2018. Rice genotypes have been used BC2F2 Siam, BC2F2 Pegagan, and BC2F2 Pelita Rampak, and their parental varieties i.e. Siam, Pegagan, and Pelita Rampak. The results showed that genotype BC2F2 had vegetative and generative characters different from those of Siam, Pegagan, and Pelita Rampak. The production of the tested rice varieties was high, ranged from 4.52 to 7.95 tonnes per hectare. The best of each genotypes planted in the first season were SM 2, PGG 4, and PLR 3. While the best BC2F2 of each genotypes planted in the second season were SM 2, PGG 3, and PLR 3.

Abstract

Combine harvester is a rice harvester that can cut the panicles of standing plants, knock down and clean the grain while crossing the rice fields. The use of combine harvester can potentially damage the soil, the soil becomes hard and the use of fuel causes potential air pollution in the rice field environment. The objectives of this study were to identify the impact of soil compaction due to the use of a combine harvester machine and to determine what physical properties affect the soil compaction due to the use of a combine harvester machine. Equipment and materials used for the sand cone test in this study include:transparent bottles, calibration funnels, plates for sand funnels, hammers, spoons, brushes, chisels, scales and sand. The results showed that soil compaction causes porosity and soil permeability was reduced so that it can inhibit plant growth. Soil compaction affects soil physical properties such as bulk density, porosity, and groundwater content.

Abstract

Way Kambas National Park (WKNP) is home of five protected big mammals including sumatran elephants.  It shares its border with 22 of 37 villages surrounding the national park.  Understanding their existence in the wild is a priority, and  wildlife genetics is a crucially needed. Besides poaching and habitat fragmentation, wildlife-human conflict is one big issue.  Elephant Training Center (ETC) in WKNP is built for semi in-situ conservation effort on captive sumatran elephants that mainly have conflict histories with local people.  Participative observation and bio-molecular analysis were conducted to learn the importance of captive Sumatran elephant for conservation effort.  Through captive sumatran elephants, database and applicable methods are expected to be developed supporting the conservation of their population in the wild.  Participative observation and molecular identification was carried on captive sumatran elephants in ETC, WKNP under multiple year Terapan grant of Ministry of Research and Technology Higher Education, Indonesia. Gene sequence and cytological analyses showed that the captive sumatran elephants are closely related and tend to be domesticated.  Translocation among ETC to avoid inbreeding, and maintaining the captive sumatran elephant as natural as possible are highly recommended. Developing genetic database can be a reference for both captive and wild sumatran elephants.

Abstract

This study aimed to know the influence of planting the flowering plants in sugarcane plantation on the index value of diversity, domination, and the eveness of phytophage and entomophage insect species in sugarcane plantation. This study was done on two-month and six-month sugarcane of PT.  Perkebunan Nusantara VII Cinta Manis District. The research location is located in Ketiau Village, Lubuk Keliat District, Ogan Ilir Regency, South Sumatra. The study was conducted from July to December 2018. Insects that came to flowering plants were collected by using fitfall traps, nets, and direct capture of insects that came. The results showed that the age of sugarcane affected the diversity of Entomophage and Phytophage insect species that came to the flowering plants. At 2-moth-old sugar cane plantations were found 42 species (388 individuals) and 6-month-old sugarcane plantations were found 41 species (284 individuals). The diversity of Phytophage and Entomophage species that came to flowering plants in  the 2-month-old sugarcane plantations was almost the same as in the 6-month-old sugarcane plantations. Phytopage species diversity index values were 2,826 and 2,548, while Entomophage were 2,564 and 2,867.
