Perancangan Freshwater Aquarium Park di Indragiri Hulu dengan Pendekatan Arsitektur Hemat Energi

Freshwater Aquarium Park in Indragiri Hulu accommodate different types of aquatic fauna and ecosystem (natural) that provides an overview of the life of freshwater without having to dive can be used as a means of recreation, education and conservation. Indragiri Hulu as a region with a thousand rivers, has the potential of fish and aquatic plants, which is not yet fully developed and there are no facilities to accommodate its Indragiri aquatic ecosystems. This design apply the principle of energy-efficient architecture with the concept of multi expression unity of design. The application of this concept in the design of Freshwater Aquarium Park that analogy as root produce different shapes on each side of the building, penzoningan which facilitate inter-space function that applies the principles of energy saving by optimizing the air, light, and water. The integration between the air system of artificial and natural, system of artificial and natural light and the synergy between passive and active methods. This building with filtration maximize water conservation and ecosystem modeling

Ways to Preserve Biological Diversity of Bog Ecosystems within Natural Parks System

Results of field research, GIS-mapping and simulation of ecosystems including relict bogs within the conservation area of a new regional Natural park are represented in the article. Functional zoning of the park area with the argumentation of different use provisions have been developed on the basis of author’s landscape pla

Pengetahuan Masyarakat Pekurehua di Sekitar Taman Nasional Lore Lindu, Sulawesi Tengah Tentang Tumbuhan Obat dan Pemanfaatannya

The Lore Lindu National Park is one of National Parks in Indonesia. This National Park belongs to Donggala and Poso district, Central Sulawesi Province, administratively total area is 229.000 Ha. The major ethnics who live in this Park are Kaili, Behoa and Pekurehua. In order to explore the medicinal plants used by them, the ethno botany study is carried out by direct interview to Pekurehua tribes in Wuasa, Poso district, Central Sulawesi, eastern part of Lore Lindu National Park. It has been known that about 104 species from 93 genera and 46 families are used as medicinal plants by Pekurehua tribes. Some of the medicinal plants have herb habits and those species can be used to cure approximately 46 types of illness. One of those species, Hiha (Alstonia scholar is) is categorized as an endangered species and it is used by them as well. Pekurehua people is not only used the higher plants as medicines but also lower plant, such as lichen (Parmeliaceae)

Nonstationary Nonlinear Heteroskedasticity in Regression

This paper considers the regression with errors having nonstationary nonlinear heteroskedasticity. For both the usual stationary regression and the nonstationary cointegrating regression, we develop the asymptotic theories for the least squares methods in the presence of conditional heterogeneity given as a nonlinear function of an integrated process. In particular, it is shown that the nonstationarity of volatility in the regression errors may induce spuriousness of the underlying regression. This is true for both the usual stationary regression and the nonstationary cointegrating regression, if excessive nonstationary volatility is present in the errors. Mild nonstationary volatilities do not render the underlying regression spurious. However, their presence makes the least squares estimator asymptotically biased and inefficient and the usual chi-square test invalid. In the paper, we develop an unbiased and efficient method of estimation and a chi-square test applicable for the regression with mild nonstationary volatilities in the errors. We provide some illustrations to demonstrate the empirical relevancy of the model and theory developed in the paper. For this purpose, examined are US consumption function, EURO/USD forward-spot spreads and capital-asset pricing models for some major NYSE stocksvolatility, nonstationary nonlinear heteroskedasticity, regression with heteroskedastic errors, spurious regression, cointegration
