Drilling system on a pile of waste to get the methane gas is very difficult because the majority of waste that is made from plastic so it can get caught in the drill. Manual excavationis not allowed because it is very dangerous, while digging with heavy equipment has not been able to do because it requires a special tool that is able to push and pull waste surface. Makingholes with arrow system method that is larger arrowhead from the arrow shaft, is one alternative that can be tried to get a hole / gas extraction wells at the Landfill Supit Urang - Malang.Results hole larger than the arrow shaft is then filled with gravels as well extration methane in the landfill. The force required pile (arrow system) to the pole with pole diameter 26.7 cm and a maximum depth of 5.20 m (at point 1, the arrows point of 30˚ and 45˚) is a row of 63,087 kg and 79,717 kg . Optimum angle in terms of penetration force needs is the pole with arrowhead angle 30˚.

This paper is the result of a research that aimed to evaluate the quality of services at Patra Semarang Convention Hotel by using the Service Quality (SERVQUAL) and Importance Performance Matrix, and provide corrective suggestions for improving service quality on some priority attribute by using Quality Function Deployment (QFD) in order to clarify the follow-up should be done to close the gap that happened between acceptable and what is expected by the customer. In this paper, evaluation of service quality is assessed through five gaps (gap 1untill gap 5) that occurred. This evaluation is done by distributing questionnaires to customers (110 respondents) and to the employee (85 respondents). Then, the results of these evaluation are placed in the quadrants contained on Importance Performance Matrix (IPM) (mapped) in order to capture the attributes that really matter to the satisfaction of the customers but their performance is still very low (negative). Result of this mapping shows that the Patra Semarang Convention Hotel should focus its quality improvement services to the five important attributes, i.e: easiness to access the information from internet, clarity of delivery of new information by employee, cleanliness of the hotel, availability of adequate parking area, and speed of employees in responding to the consumer complaints. All this important attributes will be a priority in product planning for improvements the quality of services provided.

Concrete mixing obtained from the fine aggregate and coarse aggregate is sand, stonebroken by adding sufficient adhesive cement and water as supporting material for purposesof chemical reactions during the process of concrete hardening and treatment progress, andmay also be additional material that could serve to strengthen or accelerate the development ofconcrete strength. Therefore, in order to obtain concrete with a light weight, one of which is toreplace the coarse aggregate is commonly used with natural stone aggregate is an alternativethat has a lighter weight but has the major attributes that do not differ greatly. The methodused in this study by testing it against a strong press, elastic modulus, split tensile strength,density, porosity. Increased modulus of elasticity of the variation in aggregate gradation gradationsI to III of variation 14.03%. On a good variety of aggregate inter-aggregate contact areawill be smaller so that the number of pores (porosity) of concrete produced would be smaller.With a small contact area porosity and the amount of cement needed in a similar treatment willbe less. The more small porosity variations in the use of aggregate gradation will memyebabkanconcrete gravity value greater. Small porosity values which will make the concrete moredense so that the stronger the resulting press will be great. In the strong increase in press andconcrete, will be followed by a rise in value of split tensile strength and modulus of elasticityof concrete.

Methodologically there are some problems in the methods of scheduling production whichhave been available. In the methods of scheduling production which have been available, it isoften less capable for giving the real condition images from the real systems. It is indicated bythe given assumption that each operation should be finished previously before the other operationsare done. This case is inappropriate if applied in the repetitive production types as happenedin X Gresik, Co. Ltd. Because methodologically there are some problems in the methodsof scheduling conventional production, so in this research the methods of scheduling conventionalproduction are modified by using Microsoft excel application software, so it enables inthis method to handle the case of scheduling production in the types of repetitive production.urthermore, by using the methods of scheduling production modified by using Microsoft excelapplication software, the scheduling can be achieved by the better makespan (makespan =471,17 hours), so the production facility utilities are also more optimal compared to productionscheduling results by conventional approach (makespan = 893,7 hours).

Basically, surface grinding is mechanical process that result high temperature and chemical reaction on surface work piece. On this process, the heat energy has been released along of the surface. A part of the energy would be transferred to chip and the other would be continued to the environment by grinder and work piece. Use of coolant on the surface of the object will be function as lubricant, which can reduce friction between grinder and the object. Moreover, in grinding process, cooling can effect on temperature and surface roughness. This research used factorial design 2x3x3 to evaluate the effect some variables process such as table speed, depth of cut also cooling method on temperature and surface roughness. High pressure air and air in room temperature are kinds of cooling method in the process, the result of experiment would be analysis by ANAVA. The experiment shows that temperature in air cooling method it is lowerthan by air of room temperature cooling method. The surface roughness of the work piece in air cooling method is the lowest. The faster table speed of grinding machine caused that the lower of the grinding temperature and the work piece surface roughness. Moreover, the higher depth of cut would cause the higher grinding temperature and surface roughness.

In the world of industry, insulation materials are often utilized to maintain the temperature, either low or high. However, since the insulation materials often need to be thick, thus, costly, they are frequently deemed impractical. Therefore, in the attempt to replace the insulation materials, a cavity with low vacuum pressure is opted for. Yet, to attain a total (100%) airfree cavity is not an easy task. Such, the cavity usually still bears some amount of air pressure which results in natural heat convection through the two surfaces making up the cavity. The transfer coefficient of natural heat convection (h) is influenced by some factors, such as, the temperature difference, geometry of the cavity, cavity orientation, and characteristics of the fluid, for instance, its pressure, temperature, conductivity, specific gravity (density), and viscosity. The purpose of the study is to find answers to the following question: “How do vacuum pressure variation and cavity ratio affect the rate of natural heat convection through the a cavity?” Pertinent to the question, the study was aimed to find the appropriate value of the vacuum pressurewhich can function well as an insulator. This study is significant in the attempt to lower down the rate of heat transfer taking place in a system vis-à-vis the surrounding media. The study found out that the degree of emptiness of -60 cm Hg and =5.96, results in a lower rate of heat transfer compared with -20 cm Hg and -40 cm Hg. This means that the vacuum pressure of -60cm Hg bears a bigger thermal resistance than the -20 cm Hg and -40 cm Hg do.

Nanocrystalline of Barium Hexaferrite (BaFe12O19) powders have been synthesized using the sol gel auto combustion method. The ferrite precursors were obtained from aqueous mixtures of Barium nitrate and Ferric nitrate by auto combustion reaction from gel point. These precursors were sintered at different temperatures ranging from 700 to 1000oC for constant calcinations time 2,5 h in a static air atmosphere. Effects of Fe3+/Ba2+ mol ratios and sintering temperatures on the microstructure and magnetic properties were systematically studied. The powders formed were investigated using X-ray diffraction (XRD), scanning electron microscope (SEM) and VSM. The results obtained showed that the phase BaFe12O19 powders were achieved by the Fe3+/Ba2+ mole ratio from the stoichiometric value 11, 11.5 and 12 at temperature 950OC. With increasing of temperature sintering, coercivity and magnetization value tends to rising. The maximum saturation magnetization (66.16 emu/g) was achieved at the Fe3+/Ba2+ mole ratio to 11.5 and the sintering temperature 950OC. The maximum coercivity value 3542 Oe achieved at mole ratio sample 12 with sintering temperature 950OC. Maximum saturation 6616 emu/g achieved at mole ratio sample 115 with the same temperature.
