Abstract

Pemasaran produk yang memiliki mutu tinggi dapat dikenal oleh konsumen melalui merek yang digunakan perusahaan penghasil produk tersebut. Agar mutu produk yang dihasilkan selalu konsisten setiap saat diperlukan standarisasi mutu baik di tingkat perusahaan, nasional regional maupun internasional. Di era globalisasi ini perusahaan dituntut untuk mengembangkan pemasaran produknya tidak hanya didalam negeri, tetapi juga pada skala internasional. Untuk keperluan ini perusahaan dituntut untuk memperhatikan dan mempelajari keinginan konsumen di negara dimana produknya akan dipasarkan dengan tetap membuat mutu produk yang terstandarisasi. Agar produk yang dipasarkan di tingkat internasional dapat diterima , maka perusahaan dapat menjual melalui merek yang dapat dipahami oleh konsumen setempat. Dengan demikian dapat disimpulkan, untuk perdagangan global, mutu produk harus tetap sesuai dengan standar yang telah disepakati, namun merek produk dapat disesuaikan agar dapat diterima oleh konsumen dimana produk tersebut dipasarkan yang dikenal dengan merek global.

Abstract

http://dx.doi.org/10.17014/ijog.vol3no4.20082Micromorphological characterization has been studied on six pedons of soils developing in volcanic materials in West Java. The pedons represent deposits of different volcanoes (Mount Tangkuban Perahu, Mount Patuha and Mount Papandayan) with different ages (Pleistocene, Holocene) within two types of volcanisms (andesitic, basaltic), and three agroclimatic zones (A, B1, B2). Undisturbed soil samples were taken from each identifiable horizon for thin section preparations. Observations were carried out by means of a magnifying lens, binocular stereomicroscope, polarization microscope, and scanning electron microscope (SEM). The result demonstrates that micromorphological characteristics of volcanic soils developing from different ages, types of parent material, and climate were different through their c/f related distribution 2µ patterns, c/f ratios, sorting, infillings and coatings of voids, and microstructure.

Abstract

The proper understanding about spatial soil diversity is very important to simulate environmental model and to manage land resources in the landscape scale. Information of soil diversity is also noteworthy for environmental academics, forestry, civil engineering, and land use planner. Until now, most of the soil information are derived from conventional soil maps which are lack of detailed information. This condition can increase the uncertainty of model output and can also be an obstacle to the future development of spatial distribution model. According to this situation, the research was conducted in Sub Watershed of Cikeruh, Citarik, and Citarum Hulu. These areas are located in the 6o53’00”S - 6o53’15” S and 107o45’21”E - 107o45’55”E at 780-1800 m asl, The rainfall is classified as type C according to the Schmidt and Fergusson classification with mean rainfall around 1795.66 mm per year. The soils in the research areas are classified as Inceptisols.  The research aims to analyze and elucidate the relation between topographic characteristics and soil physical properties. Some parameters studied in this research are elevation, aspect, plan curvature, profile curvature, topographic wetness index (TWI), topographic position index (TPI), and some soil physical properties, such as soil texture (clay, silt, and sand), soil organic carbon, soil bulk density, soil available water capacity, soil porosity and permeability. The results showed that all topographic parameters were related to one or some soil physical properties, except aspect and slope. Topographic variables that are frequently related to soil properties are TPI and TWI. Keywords: topographic characteristics, elevation, aspect, curvature, TWI, TPI, soil physical properties

Abstract

Soil quality test is needed to find out the influence of landuse change due to soil quality dan characteristics. This research aims to comparing various land use that influence the physical, chemical and biological soil on Andisol and Inceptisol, obtain information of soil quality at various land uses on Andisol and Inceptisol, and study the relationship between soil quality and erosion at various land use The study was conducted in Sub Sub watershed Hulu Cimanuk with an area of 16.171 hectares. The study was conducted on four different types of land use namely forest land, agriculture land, tea garden and mixed garden. The study was conducted with survey methods, descriptive and comparative. Erosion calculation using the RUSLE formula.Analysis of soil quality is calculated based on criteria Mausbach & Seybold (1998) and modified in accordance with the conditions of the study area. The results showed that each land use has a different effect on soils quality nor with erosion. Soil quality on forest land has higher value than other land use and erosion that occurs most low at 0.2 tonnes / ha / year. The use of dry land has the lowest value of soil erosion begitupula highest of 387 tonnes / ha / year.Key words: erosion, landuse change, soil quality, and watershed.

Abstract

Mineral content of the soil determines various properties including nutrient that can bereleased during the weathering process. The research to identify the minerals in Andisol developedfrom the eruption of Mt. Tangkuban Parahu and Mt. Patuha had been conducted to determine theminerals content in the sand fraction. This research was conducted in several steps: the field survey,soil sampling, and laboratory analysis. The field locations were in the forest of Cikole, Lembang,West Java derived from the eruption Mt. Tangkuban Parahu and in the forest of Patengan,Rancabali, West Java derived from the eruption of Mt. Patuha. Sand fraction was separated from siltand clay by wet sieving method, using the 50 micron siever. Microscopic observation for identifyingthe minerals was done with polarization microscope to the color, luster, shape of grains and crystals,cleavage, hardness, transparency, translucent, and magnetic properties. The results showed that thesand fraction of Andisol derived from Mt. Tangkuban Parahu and Mt. Patuha had the mineralcontent as hypersthene, diopside, orthoclase, oligoclase, anorthite, andesine, hornblende, biotite,quartz, corundum, magnetite dan sulphur, showed that the weathering those minerals cancontribute some nutrients like Mg, Ca, K Fe, and S to the soilKey words: hyperstene, diopside, anorthite, hornblende, biotite
