Abstract

Rukmini Tatwa is a traditional health and beauty Balinese script. That script was written on the leaves of palm tree (Borrassus flabellifer). The basic concepts of healthy and beauty are generally considered the integrated result of physical, mental and emotional. Rukmini Tatwa is traditional beauty that refers the practice of using natural plants substances. The script documented more than one hundred plant use, composition and therapy. The plants are prepared in various ways. Parts of plant used are the leaves, flowers, root, stem, bark, fruit, seed and tuber. Most of the concoction is made simply by grinding and pounding. Its knowledge is equal to the traditional medicine. Rukmini Tatwa illustrated to maintain the family harmony from lack of fitness and beauty as well as to solve sexual problems.

Abstract

Advanced technology in molecular biology often uses microorganism, consequently, researcher should have a responsibility in producing of laboratory products safely both for human and their environment. This presentation was intended (1) to report recombinant protein research in the Jembrana Disease Virus (JDV); (2) to identify relevancy of the ethics towards the research of recombinant protein and (3) to discuss relationship of utilitarianism principle with the development of the recombinant protein. The Jembrana disease is an infectious virus caused by a virus classified as retrovirus of Retrovidae family. The disease only attacks Bali cattle (Bos javanicus) that caused about 20% mortality rate. Up to present, crude vaccine from lymph organ of acute infected Bali cattle is often used for vaccination. Development of the Jembrana vaccine was attempted to increase the availability of qualified Jembrana vaccine by recombinant DNA approaches subsequently could be used as vaccine substances. This article was presented with much bioethics issues in associated with recombinant protein research and other examples of related research which use micro-organism in their investigation. It is expected that bioethics could be a restrain for researchers who deal with advanced technology in their investigation.

Abstract

A total of 6 fungi isolates of growing at pH 9 and 2 isolates on pH 10 with amylolytic indexes 0f 0.07-1.42 have been isolated from cassava starch liquid waste. Two isolates having the highest amylolytic index were identified as Aspergillus sydowii K10 (1.42) and Aspergillus versicolor L30 (1.4). Both A. sydowii K10 and A. versicolor L30 were described as alcalotolerant for being able to grow with range pH 5-10. The optimal -amylases production of A. sydowii K10 and A. versicolor L30 was obtained after 4 and 3 days of incubation at 300C. The optimum of -amylase activity from A. sydowii K10 was at 400C and 700C, and pH 6; while those from A. versicolor L30 was at 500C and pH 6 respectively. Both A. sydowii K10 and A. versicolor L30 could produce glucoamylase. The optimum of glucoamylase activity from A. sydowii K10 was at 400C and pH 5, while those from A. versicolor L30 was at 500C and pH 5 respectively.

Abstract

Penelitian tentang penyerbukan dan sistem reproduksi Ranunculus japonicus telah dilakukan di kebun botani Universitas Osaka City, Katano, Osaka, Japan. Hasil penelitian menunjukkan bahwa putik R. japonicus lebih dahulu masak daripada benang sarinya (protogyny). Pada tumbuhan ini terjadi ketidakcocokan silang sendiri (self-incompatible). Tumbuhan ini tidak mengalami penyerbukan sendiri (selfing) dan juga tidak membentuk biji tanpa pembuahan (agamosper my), tetapi melakukan penyerbukan silang (out-crossing) dan membutuhkan perantara (pollinator) untuk pembentukan bijinya.

Abstract

The objective of this research was to prove that galangale rhizome (Alpinia galanga L. Swartz) can be used to preserved “pindang” tuna fish (Euthynnus pelamis L.). The fish were cooked by galangale rhizome solution (the concentration were 0, 50, 100, 150, 200 mg/l b/v) for15 minutes. Then, the fish were stored in box, three fishes /box, and stored at room temperature for 6 days. Every day, The quality of fish were measured as colour, rubberness, taste, odor, total of bacteria and fungi. The result showed that there were decreased of the fish quality, spoilaged, and many fungi and bacteri growth after two days, and the level of spoilage of fish was influenced the increasing of galangale rhizome concentration. It concluded that the galangale rhizome can not use as “pindang” tuna fish preservative.

Abstract

CITES (Konvensi PerdaganganInternasional Flora dan Fauna yang TerancamPunah) telah ditetapkan tahun 1973 diWashington. Indonesia telah meratifikasinyapada tahun 1978. Namun ternyata publikasimengenai pelaksanaan CITES di Indonesiayang lengkap belum ada. Sehingga terbitnyabuku ini: “CITES Implementation in Indonesia“ perlu kita syukuri. Buku ini cukup lengkapmembahas mengenai pelaksanaan konvensiperdagangan internasional jenis jenis Flora danFauna yang terancam punah di Indonesia.Sayangnya buku ini baru ditulis dalam bahasaInggeris.

Abstract

We present a strategy to preserve the biodiversity of Sulawesi and nearby islands chains. Sulawesi is the primary landmass in the biogeographic zone known as Wallacea, and is listed as one of the world’s top 25 hotspots at threat for major loss of biodiversity. Sulawesi is hypothesized to be subdivided into regions of endemism. We argue that the best strategy for preserving the totality of Sulawesi biodiversity, given that the vast bulk of that biodiversity remains virtually unstudied or even unknown, is to use biogeographic data to make a comprehensive map of regions of endemism in Sulawesi and to protect primary habitat in each region. We present a hypothesis that we call the “hybrid biogeographic hypothesis” that synthesizes two previous biogeografic hypotheses, one from empirical biological data and one from geologic data. We present a map of tarsier acoustic group distributions that offers heuristic evidence that the former hypothesis is more comprehensive than either of the latter two. We note that some of these regions have multiple conservation areas, while several others have none at all and can be thought of as “hotspots within the hotspot”. Evidence indicates that an endemic taxon of tarsier inhabits nearly every known endemic region of Sulawesi and surrounding island chains, although most of these taxa are undescribed. We propose to use tarsiers as flagship species to justify new conservation areas that will preserve primary habitat in those regions that currently lack them. Tarsiers are superior to other potential flagship species because they have the requisite charisma and are distributed throughout Sulawesi in a broad variety of habitats, but they do not eat agricultural products or have other characteristics that might engender local resentment to their conservation. This plan requires naming several new taxa of tarsiers, each of which requires reference material. Existing museum populations are inadequate for these needs and new museum specimens are required. We argue that the most beneficial way for this program to proceed is to trap wild tarsiers and house them in captivity until they expire naturally, at which time they will enter the collections of the Museum Zoologicum Bogoriense. While in captivity these tarsiers will provide enormous opportunities for research, training, education, and conservation. We will encounter local resistance to conserving tarsier populations because of false perceptions among inhabitants that tarsiers eat agricultural products, and this false belief must be corrected through community education. The critical condition of habitat destruction in Sulawesi warrants immediate action.

Abstract

An Ethnobotanical study was carried out on a group of Talang Mamak tribe of the Bukit Tigapuluh National Park, Jambi. The inter-relationship and the dependency of the tribe with the forest plant resources were reflected by their daily lives by gathering medicine and hunting. The tribe lives surroundings HPH of the Dalek Esa Raya Co. Ltd. A number of 92 plant species were used as their food. About 70% of the species recorded were gathered from the forests, and the rest (30%) were as cultivated plant. Various botanical aspects of each species with its usage and utilization methods were discussed.

Abstract

Medusa Phyllorhiza punctata mampu menghasilkan lendir yang dapat diserap olehmolekul organik serta berperan sebagai agregat atau sumber energi bagi pertumbuhandan perkembangan bakteri. Penelitian ini telah dilaksanakan dengan tujuan untukmengetahui pola produksi karbon organik terlarut (KOT) oleh medusa P.punctata danuntuk mendeterminasi hubungan antara produksi KOT dengan produksi dan konsumsioksigen dalam proses fotosintesis. Hasil penelitian menunjukkan bahwa medusa yangberukuran kecil (berat basah < 7 gram) menghasilkan oksigen lebih banyak dari jumlahyang dibutuhkan. Sedangkan medusa yang berukuran lebih besar mengkonsumsi oksigenlebih banyak dari jumlah yang dihasilkan. Secara individual, medusa dengan beratantara 4 - 6,8 gram dapat memproduksi karbon organik terlarut sebesar 27,44 mgkarbon per hari dan medusa yang berukuran besar dengan berat 27 - 45 gram dapatmenghasilkan KOT sekitar 308,7 mg karbon per hari.
