Judul: Determination of the Transjakarta Busway Gas Pipeline Using Geographic Information System and Multicriteria Decision Making
Abstrak: Transportation and pollution has become a severe problem in many big cities in developing countries, include Indonesia especially in Indonesia’s capital city, Jakarta. Over usage of petroleum, pollution and heavy traffic problem in Jakarta has become a more complicated case in the daily life. Meanwhile, compressed natural gas (CNG) is a clean burning, high energy, alternative energy source that enables us to safely continue to build on and improve our current lifestyle in the future. Transjakarta Busway is currently preparing to use compressed natural gas for powering the busway and it will need to define the best pipeline route from the existing main gas source to the CNG Station by considering cost, safety, social conflict, etc. The objective of this research is to determine the best route for a gas transmission pipeline network that considers various criteria for minimizing adverse. The methods of this research is based on multi criteria decision making by implementing GIS model technology refers to spatial analyst and network analyst that will produce possibility alternative routes. Having established alternative routes, each criterion and alternatives should be evaluated and weighted using pairwise comparison in term of analytical hierarchy process (AHP) to identify the best route for a gas transmission pipeline into the most preferred route. The model is concerned only with distribution lines, in areas that are already largely urbanized or industrialized. The distribution pipes will be installed under the shoulder of existing roadways and beside existing utilities. So no land needs to be purchased, and no one will be displaced. There will be some very temporary (up to one day) disruption to businesses, residents, and other facilities along the roadsides and utilities as the pipe construction, dig, bury, and test the piping. This is unavoidable, but it has standard operating procedures and various prevention and mitigation measures in place, based upon long experiences, to minimize these disruptions. This model has been applied in Transjakarta Busway Corridor VII. It was found that the best CNG pipeline route was in Kramat Jati.

Judul: Strategy of PT GAS Facing Business Competition in the Downstream Natural Gas Industry Distribution of West Java and Banten Regions in Indonesia
Abstrak: Indonesia still has conventional natural gas reserves of 100.36 TSCF (Trillion Standard Cubic Feet), and 42.46 TSCF are potential reserves. Apart from conventional natural gas, Indonesia has the potential of non-conventional natural gas, namely coal methane gas known as CBM (Coal Bed Methane) or natural gas from coal and Shale Gas (Flake Gas) potential of 452 TSCF and 574 respectively TSCF. The amount of natural gas reserves illustrates the strategic value of natural gas to fulfill national energy. However, the enormous potential of gas commodities has not yet had a tremendous impact on PT GAS development. Over the past six years, the growth of PT GAS's performance has decreased. This study aims to analyze the internal and external factors that influence the business development of PT GAS, formulate various alternative business development strategies of PT GAS, and determine priority strategies that can apply to PT GAS business development. The research started from November 2018 to April 2019. Primary research data obtained from interviews and discussions with a focus group discussion (FGD) approach and the distribution of questionnaires to nine informants who were considered competent in this study were those directly involved in the preparation of the company's strategy during This was done by PT GAS. Samples took using a purposive sampling method. The data obtained were analyzed descriptively. The strategy formulation analysis consisted of the input stage using an internal and external factor evaluation matrix, the matching stage using IE Matrix and SWOT, and the decision stage using QSPM. The results showed that internal factors were affecting business development obtained from identifying the company's strengths and weaknesses and external factors obtained from opportunities and threats. Internal factor evaluation results got a value of 3.00 (strength of 2.20 and weakness of 0.80) and an external evaluation value of 3.02 (opportunity 2.33 and threats 0.69). Internal and external evaluation calculations determine the company's position in the quadrant grow and build or grow and build. The results of the IE and SWOT analysis results showed seven alternative strategies as well as the priority order of the plan after calculating using the QSPM calculation, namely a) Market Penetration b) Product Diversification c) Improving Pipe Networks d) Improving gas quality e) Improving service quality f) Company reputation g) Strengthening branding. After going through three strategic management planning stages, the next step was selecting the main strategic alternatives that use QSPM as a tool. The primary strategy that gets the highest attractiveness value (3.20) in QSPM is "Market Penetration on an ongoing basis by strengthening the marketing research base by maximizing the pipeline network that there and good gas quality as a value proposition. This strategy is the most attractive strategy for PT GAS today. PT GAS must create a strong marketing research base by strengthening marketing

Judul: Infeksi leucocytozoon Smithi (Laveran dan Lucet, 1905) pada kalkun
Abstrak: Leucocytozoon smithi adalah parasit darah yang menyebabkan leucocytozoonosis pada kalkun, dan termasuk dalam genus Leucocytozoon yang perkembangan skizogoninya terja- di dalam sel-sel endotel dan sel-sel parenkhim hati, jan- tung, ginjal dan organ-organ lain dari unggas. Genus ini menghasilkan skizon yang besar. Gametogoninya terjadi di dalam sel-sel darah dan sel yang terinfeksi dapat berubah bentuk dan mengambil bentuk kumparan. Parasit ini tidak menghasilkan pigmen dan ditularkan oleh lalat penghisap darah dari genus Simulium. Infeksi kalkun terjadi pada saat sporozoit masuk ke dalam peredaran darah dan selanjutnya masuk ke dalam sel- sel parenkhim hati. Siklus hidupnya mirip dengan siklus hidup L. simondi seperti yang diuraikan di bawah ini. Skizogoni yang terjadi di dalam hati menghasilkan skizon hepatik. Skizon hepatik dewasa menghasilkan merozoit dan sinsitia. Merozoit dari skizon hepatik memasuki eritroblas dan eritrosit dan membentuk gametosit bulat, sedangkan sinsitianya dapat masuk ke dalam sel-sel RES dan kemudian membentuk megaloskizon. Megaloskizon dewasa menghasilkan merozoit yang kemudian masuk ke dalam limfosit dan leukosit lain membentuk gametosit memanjang. Gametositgametosit ini akan menjadi makrogametosit dan mikrogametosit. Perkembangan parasit dalam tubuh vektor (Simulium), segera dimulai setelah vektor menghisap darah kalkun yang mengandung gametosit ini. Dalam tubuh vektor ini akan ter- jadi pembuahan makrogamet oleh mikrogamet (tahap gametogoni). Dari pembuahan ini dihasilkan zigot yang bergerak (ookinet). Ookinet akan masuk dinding usus vektor untuk memulai tahap sporogoni yang menghasilkan sporozoit. Sporozoit ini akan menuju ke kelenjar ludah dan dari sini dapat dipindahkan lagi ke tubuh kalkun pada saat vektor menghisap darah. Vektor untuk L. smithi adalah S. occidentale, S. nigroparvum, S. slossonae, S. nigritarse. L. smithi berbahaya, terutama bagi kalkun-kalkun muda. Mortalitasnya dapat mencapai 90 persen. Gejala klinis yang ditimbulkannya antara lain anorexia, lemas dan cenderung untuk duduk, kekurusan dan kelemahan, sesak nafas dan in- koordinasi dan terjungkal terlihat pada stadium akhir dan selanjutnya kalkun mengalami coma kemudian mati…dst
