Additional concern about warming of the global environment through the greenhouse effect has necessitated selection of compounds with shorter atmospheric lifetimes and higher energy efficiencies as substitute reï¬‚igerants for Heating, Air Conditioning, and refrigerating equipment.Several substitute compounds of the hidrocarbon were identified by similarities in normal boiling points and corresponding saturated vapor pressure characteristics. Sample quantities were obtained from ITB (Two sample corresponds with CFCIZ named Hycool HCRI2 and Hycool HCR12+LFS). Performance comparisons among these refrigerants are performed utilizing Air Conditioning System test facility in Laboratory for Thermodynamics, Engines and Propulsion System (LIMP "“ BPP Teknologi). The results show that these alternatives refrigerants exhibit better performance than CFC I 2 at the predetermined operating conditions.

On the one hand, the coastal area promises abundant natural resources, but on the other hand, there are potential threats of disaster for the people living in that area. Coastal erosion or abrasion is a threat/danger that harmful to communities in coastal areas in Indonesia. One of the areas affected by abrasion in Indonesia is Rembang Regency. This study attempted to analyze the physical and social impacts of abrasion in the Rembang Regency. This study was conducted qualitatively by utilizing Ikonos High-Resolution Satellite Imagery, field surveys, and interviews as the basis for the analysis of the impact of the abrasion disaster. Respondents in this study were communities and government officials in areas affected by abrasion which were determined by purposive sampling technique. The results of the data analysis show that the physical impacts of abrasion are classified into four categories, namely heavy damage, moderate damage, minor damage, and no damage, while the social impacts are in the form of psychological, sociological, and economic disturbances which have implications for decreasing welfare. Therefore, an in-depth analysis is needed to determine the abrasion disaster management policy in Rembang Regency.

One of the biggest problems during drilling operation is a stuck pipe in which the drill string would stick or freeze in the well. This challenge leads to a significant amount of remedial costs and time. Many researchers have investigated different factors regarding the stuck pipe. These factors include poor hole cleaning, improper mud design, key seating, balling up of bit, accumulation of cutting and caving, poor bottom hole assembly configuration, and differential pressure. Since geothermal drilling targets lost circulation zones at reservoir depth, the chance of getting stuck pipe events becomes higher. Many publications reported that lost circulation events that lead to stuck pipe events have become the top non-productive time (NPT) contributor to costs in many geothermal drilling projects. The consequences of a stuck pipe are very costly, that include lost time when releasing the pipe, time, and cost of fishing out the parted Bottom Hole Assembly (BHA), and efforts to abandon the tool(s) in the hole. Despite many observations that have been done to develop a system in avoiding stuck pipe incidents in oil and gas drilling operations using artificial intelligence (AI), few works have been developed for geothermal drilling operations. In this research, we propose a method to build an early warning system model for stuck pipe conditions based on a Support Vector Machine. Based on the experiment result Support Vector Machine Algorithm showed good performance with 89% accuracy and 81% recall for limited training dataset.
