REVIEW: Possibilities of Mount Lawu to be a National Park
AHMAD DWI SETYAWAN
Biodiversitas , 2001,
Abstract: National Park is an area of natural conservation that having indigenous ecosystem managed with zonation system and can be utilized for education, research, crop development and recreation. This concept seems still to be the most suitable technique for biodiversity conservation, and can be applied in Indonesia, where the high biodiversity richness taken place. Mount Lawu and surrounding areas are ideal location to be developed in to National Park. This is due to all criteria needed such as: the width was mare than 10.000 ha, the natural ecosystem and endemic species are still existing, having ancient sites, spiritual and aesthetic value; having typical physiography and physiognomy, as well as the high chance of developing tourism industries. Jobolarangan area is a natural ecosystem that represents the whole ecosystem and problems of Lawu Mountains. This area having quite high diversity and richness consisted of plants, animals and microbes. That development of National Park at Mount Lawu need to be supported by the formation of biodiversity conservation centers, i.e. botanical garden, wild live sanctuary, agro-tourism park, etc., so that becomes an integrated biodiversity conservation area.

Abstract: Setyawan AD. 2011. Recent status of Selaginella (Selaginellaceae) research in Nusantara. Biodiversitas 12: 112-124. Selaginella Pal. Beauv. (Selaginellaceae Reichb.) is a cosmopolitan genus that grows in tropical and temperate regions. Some species of Selaginella have widely distribution and tend to be invasive, but the others are endemics or even, according to IUCN criteria, endangered. Nusantara or Malesia (Malay Archipelago) is the most complex biogeographic region and rich in biodiversity. It is one of the biodiversity hotspot of Selaginella, whereas about 200 species of 700-750 species are exist. Selaginella has been survived for 440 mya without any significant morphological modification, but extinction of tree-shaped species. Selaginella have similar morphological characteristics, particularly having heterospore form and loose strobili; and is classified as one genus and one family. However, individual species has high morphological variation caused by different edaphic and climatic factors. Genetic studies indicate high polymorphism among Selaginella species. Selaginella had been used as complementary and alternative medicines treated to postpartum, menstrual disorder, wound, etc. Biflavonoid – the main secondary metabolites – gives this benefit and is especially used as anti oxidant, anti-inflammatory, and anti cancer in modern pharmaceutical industry. The other metabolites, trehalose, potentially act as molecular stabilizer in biological based industry. Metabolite profiles can also be used to identify Selaginella by its species, time and harvest age, and locations. Since most of Selaginella grows on moist, organically rich, and well drained soils, which is vulnerable to forest degradation and global warming, it needs more conservation priority. Biosystematics and ethnobotanical researches of Nusantara Selaginella is needed to expand taxonomic status and bioprospecting of this bioresources.

Abstract: Setyawan AD. 2009. Traditionally utilization of Selaginella; field research and literature review. Nusantara Bioscience 1: 146-158. The aims of this research were to find out traditional usage of Selaginella in medication and its other usages, especially in Java and other Indonesian Archipelago. About 200 of 700-750 world species of Selaginella was found in Indonesian Archipelago. Field research and literature review indicated that Selaginella is used traditionally to heal wound, bloody stools, internal hemorrhoid bleeding, menstrual and uterine disorder, blood expediting, enhancing body endurance and longevity of live, headache, etc. Besides that some of Selaginella are also used as raw dishes vegetable, ornamental pants, and crafts materials. The utilization of Selaginella is very limited against the amount of species and medicinal potency, it is needed an advance study on ethnobotany and phytochemistry to improve their uses.

Abstract: Setyawan AD. 2011. Natural products from Genus Selaginella (Selaginellaceae). Nusantara Bioscience 3: 44-58. Selaginella is a potent medicinal-stuff, which contains diverse of natural products such as alkaloid, phenolic (flavonoid), and terpenoid. This species is traditionally used to cure several diseases especially for wound, after childbirth, and menstrual disorder. Biflavonoid, a dimeric form of flavonoids, is the most valuable natural products of Selaginella, which constituted at least 13 compounds, namely amentoflavone, 2',8''-biapigenin, delicaflavone, ginkgetin, heveaflavone, hinokiflavone, isocryptomerin, kayaflavone, ochnaflavone, podocarpusflavone A, robustaflavone, sumaflavone, and taiwaniaflavone. Ecologically, plants use biflavonoid to response environmental condition such as defense against pests, diseases, herbivory, and competitions; while human medically use biflavonoid especially for antioxidant, anti-inflammatory, and anti carcinogenic. Selaginella also contains valuable disaccharide, namely trehalose that has long been known for protecting from desiccation and allows surviving severe environmental stress. The compound has very prospects as molecular stabilizer in the industries based bioresources.
Review: Biodiversity conservation strategy in a native perspective; case study of shifting cultivation at the Dayaks of Kalimantan

Abstract: Setyawan AD. 2010. Biodiversity conservation strategy in a native perspective; case study of shifting cultivation at the Dayaks of Kalimantan. Nusantara Bioscience 2: 97-108. Native tribes generally are original conservationists; they build genuine conservation strategy of natural resources and environment for sustainable living. Dayak is a native tribe of Kalimantan that has been living for thousands of years; they use shifting cultivation to manage the communal forest lands due to Kalimantan’s poor soil of minerals and nutrients, where the presence of phosphorus becomes a limiting factor for crops cultivation. In tropical forests, phosphorus mostly stored in the trees, so to remove it, the forest burning is carried out. Nutrients released into the soil can be used for upland rice (gogo) cultivation, until depleted; after that, cultivators need to open a forest, while the old land was abandoned (fallow) until it becomes forest again (for 20-25 years). The consecutive land clearing causes the formation of mosaics land with different succession ages and diverse biodiversity. This process is often combined with agroforestry systems (multicultural forest gardens), where the will-be-abandoned fields are planted with a variety of useful trees that can be integrated in forest ecosystems, especially rubber and fruits. These systems of shifting cultivation are often blamed as the main factor of forest degradation and fires, but in the last 300 years, this system has little impact on forest degradation. But, this is relatively low in productivity and subsistent, so it is not suitable for the modern agriculture which demands high productivity and measurable, mass and continuous yield, as well as related to the market. The increased population and industrial development of forestry, plantation, mining, etc. make the communal forest become narrower, so the fallow periods are shortened (5-15 years) and the lands are degraded into grasslands. In the future, shifting cultivation remains one of the Dayaks option to meet the needs of rice, but agroforestry should be developed because of its higher economic value.
Review: Effect of global warming on plant evolution and diversity; lessons from the past and its potential recurrence in the future

Abstract: Setyawan AD. 2009. Effect of global warming on plant evolution and diversity; lessons from the past and its potential recurrence in the future. Nusantara Bioscience 1: 43-52. Lessons from the past shows that global warming and glaciation is a natural cycle of repeated, the trigger factor is not always the same, but global warming is always accompanied by elevated levels of CO2 and greenhouse gases in the atmosphere which cause the other rising global temperatures. Present and destruction of various plants and other living makhluh continue to happen from time to time. Every era has its own life form, as a mirror of global environmental conditions at the time. Biodiversity is not always the same between one period of global warming are with the next global warming, or one period of glaciation that one with the next glaciation, although new breeds always show traces the evolution of his ancestors. Man is one of the agents of global warming that began with the development of agricultural systems since 8000 years ago. The impact of climate change due to global warming should continue to be wary of. Based on past experience, global warming is always followed by mass extinctions, but various forms of life will still survive even though its shape is almost certainly not the same as before. Living organisms can survive it will evolve into new taxa that are different from its parental taxa. Humans who were present at that time probably were not a men who are present at this time, given Homo sapiens may have been extinct for not being able to adapt or otherwise has evolved into a new man who may no longer shows characteristics of human wisdom.
