Abstract

Many researchers were conducted using geotechnical sentrifug in studies of the environment. The advantages of using a geotechnical sentrifug are quick to obtain the results, less materials used, economical and can be controlled for factors that are not required in the test. All geotechnical sentrifugs that were conducted are located outside from Indonesia and Malaysia, so that requires for build a geotechnical sentrifug in the country. Engineering methodology was to modify the existing geotechnical sentrifug in other countries. The geotechnical sentrifug that was build Universiti Kebangsaan Malay-sia is 50 cm radius beam type geotechnical sentrifug with dead lock capacity 6 kg and maximum acceleration around 75 gravity. The main components are body, arm, bucket sample, counter weight, motor, contaminant bottle and computer. The geo-technical sentrifug is equipped with speed sensor, close sensor, stroboscope sensor and vibration sensor. This geotechnical sentrifug was conducted in environmental studies.

Abstract

Kebo-Butak Formation was known to be the oldest volcanic rocks limited in regional terms in the lower Baturagung Hills, Gedangsari area, Gunungkidul Regency. The main constituents of the Kebo-Butak Formation consist of intersection of volcanic-clastic rocks and calcareous sediments, locally also found basalt lava with pillow structures; which distinguished it from other volcanic rock formations in the Southern Mountains. This study aims to determine the relationship of volcanic rocks exposed in Giriloyo with the Kebo-Butak Formation in the Baturagung Hills; the chronostratigraphy and the history of volcanic activities that produced the volcanic rocks of Giriloyo. This research was approached by volcanic geological mapping using surface mapping suported by gravity anayses. From the bottom to the top of the frontier areas result volcaniclastic rocks consisting of black tuffs with several fragments of volcanic bombs with basalt composition intersecting with thin basaltic lava inserted by calcareous claystone having an age of N5-7 (Early Miocene); pyroxene-rich basalt volcanic sequence consists of thick layers of tuff with creamy-brown color intersecting with lava and breccia inserted by calcareous sandstone aged N7-8; dikes, lava and agglomerates with basaltic composition and lava and agglomerates with andesitic composition. Stratigraphically, the volcanic rocks exposed at Giriloyo correlated with the volcanic rocks exposed at Karangtalun (Wukirsari) were under the Semilir Formation, bordered with normal fault N210oE/77o, the hanging wall composed by light grey tuff of Semilir Formation. Gravity analyses found high anomalies below the Semilir Formation exposed at Karangtalun-Munthuk (east of study area) continued to below the Giriloyo area. The high anomalies were identified as the igneous/ignimbrite volcanic sequence. Descriptively and stratigraphically, the Giriloyo volcanic sequence are a part of Kebo-Butak Formation. The petrogenesis of the volcanic rocks will be discussed in further research to interpret magmatological properties, the evolving paleo-volcano, and the absolute age of the rocks.

Abstract

Daerah sekitar pesisir Kecamatan Dukuhseti didominasi oleh kawasan pemukiman dan lahan tambak. Banyaknya penggunaan lahan tambak berpotensi menyebabkan tingginya salinitas air tanah di Kecamtan Dukuhseti, karena lahan tambak menggunakan air asin sehingga sangat mudah merembes ke dalam tanah baik melalui atas permukaan ataupun bawah permukaan tanah. Tujuan penelitian ini adalah mengetahui tingkat dan sebaran salinitas air tanah di Kecamatan Dukuhseti. Teknik analisis yang digunakan dalam penelitian ini adalah analisis deskriptif kuantitatif berdasarkan klasifikasi salinitas Goetz, dan klasifikasi zona konservasi air tanah Departemen Energi Sumber Daya Mineral. Hasil penelitian menunjukkan bahwa salinitas air sumur di wilayah Kecamatan Dukuhseti memiliki nilai 0 mg/l sampai dengan 15.000 mg/l. Salinitas yang terdeteksi masih dalam katagori tawar-payau. Berdasarkan zona konservasi air tanah Departemen Energi dan Sumber Daya Mineral air tanah di Kecamatan Dukuhseti masuk kedalam 3 kategori yaitu aman, rawan, dan kritis. Kadar salinitas pada air tanah sebagian besar dipengaruhi oleh jarak dari garis pantai dan penggunaan lahan tambak.

Abstract

Banaran Village, Magelang District, is one of the villages producing stone crafts thathave high selling power such as mortar, pots and statues. However, waste rock fragmentsare a lot of problems for residents. In other hand, organic and non-organic waste that isaround the residents environment is also another problem that needs to be sought asolution. So that people need to be given insights about other functions of the rubbish,namely by utilizing it into stone temple crafts, planting media, organic fertilizer and fuel.The method of implementation is carried out with socialization to the community andtraining. As a result of this dedication, the residents of Sedayu are able to make wasteproducts into other products in accordance with the waste that is owned around theirrespective neighborhoods

Abstract

The springs in Grabag Sub-district have decreased the quantity of water because of a large amount of water taken from the springs by the residents and PDAM. This can threaten the volume of existing springs. This study aims to analyze the quantity vulnerability of the spring area and identify the conservation in the management of springs in the study area by using a Geographic Information System (GIS) application. The data used is the observation of data in the field and laboratory. Data as soil type, morphometry, constituent lithology, land use, vegetation, water discharge, access, and use of water. We classify the vulnerability of springs in the study area as low - medium vulnerability. Areas of low vulnerability, vulnerability class 2.0–2.6 are scattered in the springs of Tuk Ngrancah, Tuk Tlogosari, Tuk Gedad, and Tuk Tlogorejo. This area is composed of colluvial deposits of regosol soil, low rainfall (1750–2250 mm/year), sloping slopes (9-15°), and they used the land as gardens. Medium classification areas, with vulnerability class 2.7–3.3 spread over the springs of Tuk Bleder, Tuk Mas Kalimas, Tuk Kembar, and Tuk Udal. This area is composed of colluvial deposits of latosol soil, moderate rainfall (2250-2750 mm/year), undulating slopes (16-25°), and land use as gardens. The direction of spring conservation techniques is as agronomic conservation techniques with vegetative methods. The application of this method to springs with low vulnerability classification is the use of bamboo (Bambusa sp.) as a ground cover plant. Coffee liberika (Coffea liberika) together with lamtoro (Leucaena leucochephala) and sugar palm (Arenga pinnata) were directed to springs with moderate susceptibility classification. The existence of agro-tourism land through coffee cultivation is the direction of agronomic conservation techniques in Grabag District.

Abstract

ABSTRAKTrikloroetilen (TCE) adalah pelarut organik yang sering digunakan dalam proses industri. TCE adalah salah satu contoh dari Non Aqueous Phase Liquid (NAPL) yang sudah banyak mencemari tanah dan air tanah. Tujuan penelitian ini adalah untuk mengetahui sifat-sifat pergerakan TCE dalam berbagai jenis tanah yang berbeda, mengkaji sifat-sifat pergerakan TCE dalam tanah dengan menggunakan kecepatan 1 dan 25 Gravitasi, dan mengetahui faktor-faktor yang mempengaruhi pergerakan TCE dalam tanah. Sifat pergerakan TCE dalam tanah riolit dan granit adalah TCE akan masuk langsung secara vertikal dan horizontal dalam tanah hingga ke dasar tanah. Pergerakan TCE akan terhambat pada tanah yang banyak mengandung partikel berukuran kecil. Pergerakan TCE secara vertikal pada gaya 1G dan 25G dalam tanah granit adalah paling cepat berbanding dalam tanah riolit. Pergerakan TCE dalam tanah kering dipengaruhi oleh sifat tanah terutama ukuran butir dan Kapasitas Pertukaran Kation (KPK).ABSTRACTTricholoroethylene (TCE) is an organic solvent used in many industrial processes. TCE is one of Non-Aqueous Phase Liquid (NAPL) which has already contaminated soil and groundwater. The objectives of this study are to determine the migration of TCE in rhyolite and granite soil, to determine the migration of TCE in soil using 1 and 25 Gravity (G) force, and to determine the migration of TCE influencing factors in the soil. The characteristics of TCE migration in rhyolite and granite soil will migrate vertically and laterally to the bottom of the ground. The migration will be retarded in small particle size of soil. The fastest migration of TCE at 1G and 25G was found in the granite soil. The migration of TCE in dry soil is affected by properties of soil particularly particle size and cation exchange capacity.
