A system can be subjected to excessive vibration if the force acting on it approaches the natural frequency of the system. The way to do it, especially for single operating frequency, is adding the dynamic vibration absorber. Generally, the dynamic vibration absorber is a mass-spring-damper addition to the main system. This study researches the effects comparison of Without Dynamic Vibration Absorber and Series Double Dynamic Vibration Absorber on the main system response. Electric motor with unbalanced masses is used as the exciter and placed on the two beams. The main mass is supported by these beams. This system has the specified dynamic equations. The main system response absorber TDVA addition gives 0.008291meter displacement rms at 1, 002 frequency-ratio. The one with DDVA system response absorber with Ma1=1/20 and Ma2 =1/20, Ma1=2/30 and Ma2 =1/30, and Ma1=1/40 and Ma2 =1/40 gives 0.001484 meter, 0.002691 meter, and 0.001343 meter. The system with SDVA gives better response than DDVA. The first absorber mass ability to reduce main mass response is disturbed by the second absorber mass existence.

. Hydraulic fracturing is one of the stimulation method that aimed to increase productivity of well by creating a high conductive conduit in reservoir connecting it to the wellbore. This high conductivity zone is created by injecting fluid into matrix formation with enough rate and pressure. After crack initiate and propagate, the process continue with pumping slurry consist of fracturing fluid and sand. This slurry continues to extend the fracture and concurrently carries sand deeply into formation. After the materials pumped, carrier fluid will leak off to the formation and leave the sand holds the fracture created. TLS Formation in X and Y Field is widely known as a formation that have low productivity since it has low permeability around 5 md and low resistivity 3 Ohm-m. Oil from TLS formation could not be produced without fracturing. This formation also have high clay content, 20 – 40 % clay. Mineralogy analysis also shown that this formation contains water sensitive clay such as smectite and kaolinite. Hydraulic fracturing has been done in this field since 2002 on around 130 wells. At the beginning of hydraulic fracturing campaign, the success parameter is only to make the wells produce hydrocarbon in economical rate. As the fractured wells become larger in number, several optimization is also been done to increase oil gain. Later on, the needs of conclusive analysis to evaluate well performance after hydraulic fracturing rise up due to sharp decrement of crude oil price. Accurate analysis and recommendation need to be conducted to assess the best candidate for hydraulic fracturing to maximize success ratio. Even though a common practice, candidate-well selection is not a straightforward process and up to now, there has not been a well-defined approach to address this process. Conventional methods are not easy to use for nonlinear process, such as candidate-well selection that goes through a group of parameters having different attributes and features such as geological aspect, reservoir and fluid characteristics, production details, etc. and that’s because it is difficult to describe properly all their nonlinearities. In that matter, Artificial Intelligence approach is expected to be an alternative solution for this condition.

Mechanical Alloying (MA) / Mechanical Milling (MM) is a process of processing of solid metal powders including the union and re-destruction of powder particles by using high-energy ball mill. The difference depends on whether material transfer is involved or not during processing. The study was conducted by analyzing the effect of the mechanical milling process by comparing the microstructure and mechanical properties of the copper-iron between the ones before milling (sample 1) and after milling for 2 hours (sample 2). The sample was made into a green compact cold pressing process with an emphasis system using mechanical mechanisms and dual emphasis techniques. Sintering process using continuous type machine with conveyor belt mesh and furnace type is muffle. After that cooled with natural water jacket process. Vicker hardness testing and strength testing (tensile strength test) is performed to determine the mechanical properties of copper-iron alloys that occur. The mean value of sample 1 hardness (before milling) was 39.8 HV. The mean value of sample hardness 2 (after milling) was 74.9 HV. The value of the yield strength (σ) of sample 1 is 17.597MPa, and the value of ductility (ε) is 0.119. The value of the yield strength (σ) of sample 2 is 18.547MPa, and the value of ductility (ε) is 0.073. The observation of micro structure was done to know the physiological surface of the alloy formed and to know the distribution of the composition. Observation of sample microstructure 1 shows solid phase formation ε (silver color) is an area of iron element formed with large size. Solid phase γ (orange color) is an area of copper element formed with large size. The visible elements are copper (Cu) and iron (Fe) which have a large percentage formed with large size (> 50 μm), and the pore is also large (> 50 μm). For carbon element (C), it looks gray, with a small amount. For other elements, such as zinc (Zn), phosphorus (P), and Tin (Sn), generally, they are at the grain boundary of iron (Fe) and copper (Cu) elements. Observation of sample microstructure 2 shows solid phase formation ε (silver color) showing iron area area formed with smaller size. The solid phase γ (white color) shows the copper element area formed with a smaller size. The elements seen are copper (Cu) and iron (Fe) with a small size (<50 μm), and small pores occur. From the test results and analysis showed that by shrinking the size of metal powder by milling for 2 hours can increase the hardness and yield strength of the product. Although the product becomes more brittle which is indicated by the decreased ductility value.

Cementing is the process of pushing a number of slurry which flows from the bottom of the casing shoes to rise to the annulus between the casing and formation. The cement slurry will harden so that it binds between the casing and the borehole wall. According to the purpose of cementing can be divided into two, namely Initial Cementing (Primary Cementing) and Second Cementing or Cementing Repair (Secondary or Remedial Cementing). If the Primary Cementing results are not perfect and have problems, then Secondary or Remedial Cementing will be done. Secondary or Remedial Cementing can be divided into three parts, namely Squeeze cementing, Re-cementing and Plug-back cementing. In this case, the author emphasizes on one of the Secondary or Remedial Cementing namely Squeeze Cementing.

Coal bed methane (CBM) is an unconventional energy resources in which the main ingredient is methane gas formed in the process of formation of coal (coalification). Based on research Advance Resource International inc. (ARI), the CBM resource potential is 453 Tcf spread across 11 basins in Indonesia. CBM technology is expected to be one of the alternative energy can play a role in helping to suppress the natural gas needs of oil as one of the energy commodities di Indonesia.This paper discusses about a calculated initial volume of gas in place (Gas in Place) on CBM reservoir “X” field. This initial gas volume calculation first calculating the gas content is becoming an important parameter in calculating the initial volume. This content gas value can be obtained through data analysis proximate such as ash content, moisture content, volatile matter, fixed carbon which such data can be obtained from laboratory results. But there is also the calculation of the gas content which can be obtained by simply using coal density data using several methods of calculation, such as the Mavor method, Bambang, Modified Kim, and Mullen method. In the “X” field there are five wells coalbed methane drilling has been done, namely, SS-1, SS-2, SS 3, SS-4 and SS-5 and there are five layers are seam-1, seam-2, seam-3, seam-4, and seam-5. Based on the calculations were also obtained in the “X” field coal rank, the average is sub-bitminous. Of the five wells will be calculated gas content and the initial volume of gas using a method Mavor, Bambang, Modified Kim, and Mullen.Using four methods then the gas content in the SS well ranged between 200-500 SCF / ton. And assuming that the well drainage area (A) covering an area of 100 acres, the obtained large volumes of coal bed methane wells SS-1 with the four methods ranged from 3-9 BSCF, the SS-2 ranged between 1-3 BSCF, wells SS- 3 are 2-5 BSCF, the SS-4 range between 1-3 BSCF and the SS-5 ranges between 1-3 BSCF.We will be compared the initial gas volume in the Field “X” using the four methods with data from the laboratory result. From that analysis it can be proved that the Bambang method is the most suitable method and represents CBM field in Indonesia. So the initial gas volume in Field “X” is using the result from Bambang method, and the result are 5312.17 MMscf on the SS-1well, 2385.77 MMscf on the SS-2 well, 3330.84 MMscf on the SS-3 well, 1635.44 MMscf on the SS-4 well, and 1608.74 MMscf on the SS-5 well. And the total initial gas volume in the “X” Field is 14273 MMSCF.

This study discusses the modification of the fuel system in the Komatsu HD 1500-7 unit, which aims to improve PA (physical avaibility) and make unit downtime faster. The basis of this research was carried out because of the frequent replacement of fuel filters due to clogged fuel flow so that the cost of repairs and the consequences of not operating the unit became high. This repair process uses the main components in the form of Arduino Mega 2560 program, LED lights, LCD monitors and sensors. The working principle of this improvement is that the tool works together to forward the voltage signal from the sensor to Arduino, then the signal will be converted into writing data on the LCD. The LED light functions as a warning lamp and the speaker in the cabin functions as a warning sound. The result of making this modification system is that it can be determined the right time to replace the fuel filter before a deadlock occurs and cause the unit to die suddenly.Keywords. fuel system, Physical Avaibility, Downtime

Abstract. This work presents step-by-step procedure of modeling accurate interaction potential energy between hydrogen and outer surface of zigzag Single Walled Carbon Nanotube (CNT) as a function of its diameter. First principles calculations at MP2 method level and def2-SVP basis-set were performed to predict the interaction potential energy of hydrogen gas molecule on outer surface of CNT cluster model. The result shows that the physisorption energy is ranging between 1.05 kcal/mol to 1.14 kcal/mol. Using force-matching method, Lennard-Jones potential parameters were approximated for interaction between united-atom model of hydrogen molecules and the CNT. Assuming constant σ = 3.2 Å, the result shows that the ε parameter can be defined as a function of CNT diameter.Keywords.
