The Kapencar Village, as one of villages on the slope of Sumbing Mountain, hascosmological concept of spatial setting. The phenomenological research, was done by theresearcher as own instrument, explored for finding the spatial cosmological value in theKapencar villages. Some results of the research are:1) The Kapencar Village as the Glondongvilage, expresed the mon-copat concept, with the Kapencar village as the centre. 2) keblatwetan as a cosmological concept. Wetan orientation as a symbol of the start of living or thevery previous time of people living. Two cosmological concepts of spatial setting expresed theKapencar Village has the grand cosmologycal concept in people lining, there is keblat papatkalimo pancer (four orientations and the centre as the fifth oerintation).Kata kunci : Cosmology; the slope of the mountain settlement; spatial setting

Pengaruh Sambaran Petir Langsung pada Variasi Ketinggian Menara Vertikal terhadap Tegangan Induksi yang Dirasakan oleh Jaringan Distribusi Disekitarnya
Utama, Budi
If the top of telecommunication towers or radio or television have been struck by a lightning, distribution lines in the vicinity of those would immediately underwent an induced overvoltage impuls. Magnitude of the induced voltage impuls depend on how tall the tower above ground. Such lightning stroke is type of an indirect lightning stroke which is always appear in the problem of the induced overvoltage phenomenon on overhead distribution lines. Examinant of the effects of various height of the tower and the distance parameter between the tower and the route of distribution line on rate of rise of the induced voltage of the lightning is undertaken in this paper, and the computer is as its simulator. The method of the simulation of a lightning stroke in the vicinity of distribution line and its formulation is adopted from a simulation model that has been_ proposed by Ishii et al. (1994) and Eriksson et al (1982) respectively. The result of the simulation show that presence of a vertical tower structure in the vicinity of the distribution line route will result in a lower induced voltage (on the order of 13.4 %), and effect of tower height parameter is very significant for the assumed conditions. It is proposed that this significant parameter be studied extensively in order to predict the induced voltage accurately.

The objectives of the research were to find out the parameters of the hydrolysis reaction rate (k,,) and partition coefficien (Kr) of glyphosate herbicide in saturated soil system, to identify the variables affecting those parameters, and to develop the empirical equations corelating those parameters to the pertinent variables.The experimental work or physical simulation in laboratory was conducted in a batch reactor. The sterilized soil 5 gram put into a 1000 cm3 of Erlenmeyer glass and 500 cm3 of glyphosate solution with 8 g/1 concentration was added. The Erlenmeyer mouth was covered with plastic film and the entire Erlenmeyer surface was covered with aluminium foil to minimize vaporization and photolysis reaction. The solution was mixed continuously with magnetic stirrer. At the initial time and selected time intervals, 5 cm3 of the samples were taken with syringe. The samples were centrifuged and filtered, 1 cm3 of the filtrate were analyzed its glyphosate concentration with UV- VIS. The experiments were conducted for various soil types, and the empirical correlation between the hydrolysis reaction rate (k,,) and partition coefficien (Kr) with the affecting variables can be developed.Based on the laboratory data and the simulation of mathematical model, it could be concluded that the empirical correlation between the Kr and kh values with the affecting variables could be represented in the equations:Kr =11.035 (%organic matter) + 0.25 (%clay mineral) mL gramkh =1.0810 (%organic matter) + 1.5310-5 (%clay mineral) min-1
