Abstract

Abstract. Behavior setting is the user's behavior towards the environment in forming spaces according to activities. With the development and population growth problems arise in the use of land, especially customary land. The issue of unclear structuring patterns, applicable legal dualism, and control of land from communal land belonging to a people becomes SHM that occurs in overseas areas. Overseas area is the development area of ​​the original Minangkabau luhak region. Where customary law has been combined with state law. Departing from these issues the question arises how the behavior setting in the process of obtaining inheritance land related to the layout of land and buildings and circulation paths obtained. Primary and secondary data is obtained through drawing, photographing, writing, interviewing, and obtaining documents related to the Minangkabau customary inheritance process. Supporting data obtained through the study of literature and regulations - regulations. Analysis is carried out using a behavior setting approach through user studies, activities and needs to obtain a typology of spatial use patterns that produce a place center mapping. To obtain the pattern of arrangement, history or phenomenology of inheritance and use of traditional land. Data analysis was supported by triangulation through traditional figures, indigenous peoples' speakers and literature related to behavior settings. The results obtained that there are three typologies of users in the utilization of inheritance land inheritance, namely the inheritance of the family inheritance space on the side of the road, the inheritance typology behind the family inheritance space, and the inheritance typology of migrant inheritance space behind the inheritance space. Keywords: behavior setting, customary law, inheritance space pattern, ulayat land

Abstract

Manajemen konstruksi menjadi salah satu penggerak untuk membantu proses pembangunan proyek konstruksi dengan memperhatikan pengendalian manajemen itu sendiri guna menentukan standar yang sesuai dengan perencanaan. Faktor-faktor yang mempengaruhi kesuksesan operasional proyek konstruksi antara lain adalah faktor pengendalian mutu, faktor pengendalian biaya, faktor pengendalian waktu, dan faktor pengendalian K3 (kesehatan dan keselamatan kerja). Tujuan penelitian untuk mengetahui bagaimana pengaruh dari keempat faktor pengendalian tersebut terhadap kesuksesan operasional proyek konstruksi. Penelitian dilakukan dengan menyebarkan kuisoner tentang pengendalian manajemen konstrusi kepada site manager atau staff lapangan yang sedang mengerjakan proyek di Kabupaten Sleman dan Kota Madya Yogyakarta. Data yang sudah terkumpul dianalisis dengan menggunakan metode mean, standar deviasi dan uji regresi linier dengan bantuan program SPSS 22.0. Hasil penelitian ini menyatakan bahwa pengaruh faktor pengendalian mutu, faktor pengendalian biaya, faktor pengendalian waktu, faktor pengendalian kesehatan dan keselamatan kerja berpengaruh sebesar 67,3% terhadap kesuksesan operasional proyek. Hasil analisis regresi menunjukkan bahwa faktor pengendalian waktu dan faktor pengendalian kesehatan dan keselamatan kerja berpengaruh negatif terhadap kesuksesan operasional proyek yang dapat disimpulkan bahwa apabila faktor pengendalian waktu dan faktor pengendalian kesehatan dan keselamatan kerja tidak terpenuhi dengan baik kesuksesan operasional proyek konstruksi akan menurun. Kata kunci: Manajemen, Pengendalian, Kesuksesan.

Abstract

ABSTRACT Mining activities have many impacts, one of them is changes of land use. The effect of land use affects the potential for water absorption which will have an impact on the availability of groundwater both in quantity and quality. The reduction in groundwater potential in the mining area is very possible because the elevation of the mine openings will be below the surface of the ground, especially the surface of the groundwater. This reduction in groundwater potential will affect the decrease in groundwater level, groundwater discharge, and decrease in land surface which can cause pollution. Therefore, it is necessary to analyze the vulnerability of groundwater to become a reference in groundwater management. The method of analyzing groundwater vulnerability has grown quite a lot in recent years. To find out the groundwater vulnerability method that is suitable for the mining plan, the authors compare several methods by looking at their strengths and weaknesses based on literature studies. The method of analyzing groundwater vulnerability to the mining plan aims to determine the potential for pollution and as a reference in making mining facilities and infrastructure. The SI and DRASTIC method is the most suitable method for determining vulnerability of groundwater groundwater for a mining plan. Keywords: vulnerability, groundwater, methods, mining, drastic.

Abstract

Rock mass is an arrangement composed of several intact rocks. The strength of rock mass can be know from testing the intact rock. Basically, the characteristics of intact rock are continuous. In fact, it is discontiuous, anisotropic, and homogeneous. Therefore, the analysis to determine the characteristic from intact rock to rock mass is required to obtain the same or representative characteristic. The aims of this research were to analyze the effect of rock sample size toward uniaxial compressive strength values and to analyze the spesific energy of each sample size. This research was carried out at Geomechanics Testing Laboratory of Stone Engineering and Engineering Design Yagyakarta, while the rock sampling was carried out at Polowijo Gosari Ltd, Gersik Regency,East Java Province. The results of research demonstrated that the averages of uniaxial compressive strength for rocks sample 50mm, 80mm, and 120mm were 1.396 Mpa, 1.274Mpa respectively. The specific energy needed in the uniaxial compressive strength test for different sizes of rock samples 50mm, 80mm, and120mm were 2.899MJ/ m3, 7.25MJ/ m3, and 6.652MJ/ m3 Keywords: Effect scale, Uniaxial Compressive Strength, Dolomite Stone

Abstract

The use of concrete for construction materials is currently very large, so the demand for cement is also getting bigger, consequently the price of cement is more expensive. In order to reduce the use of cement, variations in cement were tried with limestone powder, where the limestone powder contained silica, calcium carbonate, aluminum and magnesia similar to the constituent of cement. In this study the use of limestone powder in proportion with cement. It is hoped that the optimal characteristic results (density and slump) will be obtained from the proportion of cement with the limestone powder. The study made the proportion of limestone powder of 0%, 5%, 10%, 15% and 20% of cement. The results obtained are based on the optimal characteristics of the proportion of cement and limestone powder that is in the proportion of 10%. Keywords: Concrete, limestone powder, cement and slump.

Abstract

Amman Mineral Nusa Tenggara is one of the largest mining companies in Indonesia which processes copper ore into concentrates with associated minerals in the form of gold and silver. PT. Amman Mineral (PT. AMNT) processes rocks that have high levels in advance while for rocks that have low levels will be collected in the stockpile. The buildup of rocks in the stockpile causes an oxidation process in the ore rocks to be processed. The initial stage of processing using the Controlled potential sulphidisation flotation method is by taking samples and then sample preparation includes drying, comminution using jaw crusher and roll crusher, homogenization using coning & quartering, riffle and rotary splitter, and grinding using a rod mill. CPS flotation uses NaSH as a sulfidizing agent, which is a chemical that modifies the potential for sulfidization besides the chemicals used are dhitiophospate, potassium amylxanthate, frother (F583) and lime. At this research location, PT. AMNT can produce recovery from standard flotation which is lower than CPS and sulphide / oxide flotation, sulphide / oxide flotation with conditioning time variations. Keywords: Flotation, conditioning time, ore stockpile
