Begonia is a plant from the flowering tribe of Begoniaceae which still has not revealed much diversity and potential. Begonia recorded in Borneo includes Brunei 21 species, Kalimantan 5 species, Sabah 82 species and Sarawak 96 species. Generally begonias are found in calcareous rocks also in sandy and granite rocks. Begonia can also be found around waterfalls or small streams. Begonia grows from lowlands to hilly forests. This study aims to identify the Begonia genus in Bengkayang Districts. This study uses an exploratory method by exploring the entire area from corner to corner by using the length of the observation path from the river bank to the height level representing ecosystems and vegetation on the location studied. Result of research there are species of Begonia serianensis C. W. Lin & C.-I Peng., Begonia promethea Ridl. Begonia calcarea Ridl., Begonia bawangensis Hughes. sp. nov. (in prep.) dan Begonia magnicarpa C.W.Lin & C. I Peng.Keywords: Bengkayang District, Identification, Litophyte Begonia.Begonia merupakan tumbuhan berbunga Begoniaceae yang masih belum banyak terungkap keanekaragaman dan potensinya. Begonia yang terdata di Borneo meliputi Brunei 21 spesies, Kalimantan 5 spesies, Sabah 82 spesies dan Sarawak 96 spesies. Umumnya begonia terdapat pada batuan berkapur juga di batuan berpasir dan granit. Begonia juga dapat ditemukan di sekitar air terjun atau aliran air kecil. Begonia tumbuh dari dataran rendah hingga hutan perbukitan. Penelitian ini bertujuan untuk mengidentifikasi spesies dari genus Begonia yang ada di Kabupaten Bengkayang. Penelitian ini menggunakan metode eksplorasi dengan menjelajah seluruh kawasan dari sudut ke sudut dengan mengunakan panjang jalur pengamatan baik dari tepi sungai sampai pada tingkat ketinggian yang dapat mewakili ekosistem maupun vegetasi pada lokasi yang diteliti. Hasil penelitian terdapat lima spesies, yaitu Begonia serianensis C. W. Lin & C.-I Peng., Begonia promethea Ridl. Begonia calcarea Ridl., Begonia bawangensis Hughes. sp. nov. (in prep.) dan Begonia magnicarpa C.W.Lin & C. I Peng.Kata kunci: Begonia litofit, Identifikasi, Kabupaten Bengkayang.

Deformation Plane

A systematic study has been carried out concerning ground water in faults and fractures in a granite rock and the results are compared with those of uniaxial testing of granite specimens in rock mechanic laboratories. Dikes of diabase intersect the granite and indicate the plane of deformation syntectonic to the dikes. A collection of the tectonic data from the granite is statistically treated and the tectonic picture of the area fits very well into the deformation plane, indicated by the intrusion (Jotnian). The faults and fractures of the granite are, according to their position in relation to the plane of deformation, hypothetically interpreted as tension and shear faults. The faults in shear position are supposed to be tight and have very little ground water. The tension faults, on the other hand, are supposed to be open and to be capable of a high yield of ground water. This hypothesis is tested by core-drillings, percussion drillings and test pumping.

South Aceh has abundant natural resources, one of which is granite rock, at Kutablang Village and Lubuk Layu Village, Samadua District. This research discusses about minerals phases using the X-Ray Diffraction method. The results obtained in the phase of the granite constituent minerals from Kutablang Village were C16AlClN16S4, O2Si, and F15Mo5O15Rb15, and the phases of the constituent minerals from Lubuk Layu Village were O2Si, F15Mo5O15Rb15 and La2Mo2O9.

Nature has blessed with natural resources like rocks / minerals, vegetation, air and water. These are about one crore eighty six lakhs living creatures existing in the world. Most of the living creatures are using their intellect and residing in the natures nest, where as human being is blessed with unique knowledge and wisdom which propelled to discover wheel, moving machineries and established good shelter with ultra architectural designs. Ancient man was living in huts further more constructed mud houses with the available clay / mud. Over a period of time man discovered calcium oxide to use in construction. In 1840s, a scientist by name William Aspdin has invented the manufacturing process of Portland cement production. Over a period of time, lot of advancements took place in producing different types of cement. During 1950’s fly ash was considered as a waste and used to land fill /dumps. Over a period of time man discovered compatible chemicals in fly ash and successful in mixing Ordinary Portland cement up to 30% which is called Pozzolana Portland cement. Several Researchers tried different waste materials to be used as a potential, concrete mix and have been successful in doing so. This paper deals in reviewing potential waste materials being used in cement concrete. Granite rocks are sliced to fine plates for the utility as flooring material. In the process of cutting and smothering the granite, fine dust of approximately 50µm is generated. Researchers discovered compatibility of granite saw dust in cement mix and were successful. Everyday hundreds and thousands of tones of plastic waste is generated. Researchers also tried to use plastic waste in civil construction and partially successful as plastic is organic in nature where as cement is inorganic in nature, nevertheless plastic waste is found as a potential mix in laying bitumen road. Limestone which consists of calcium atom and oxygen atom exists naturally in certain areas where as calcium oxide is also produced synthetically by cracking calcium carbonate at approximately 1000oC. Researchers have been successful in using calcium oxide, municipal waste in civil construction at different proportions. The optimal quality of final cement is governed by particle size and its distribution. Therefore adequate review is also done in terms of particle size, distribution and quality. The current objective of this review article is to give an insight about the sustainable technologies in cement using waste materials disposed in abundance.
