Bali Botanical Gardens take website advantage of existing services to promote the service program in the field of conservation and environmental education as well as contributing to socialize about preserving the environment. Bali botanical gardens provide a variety of information with the submission that is easily understood by tourists who want to visit. Bali Botanical Gardens itself makes the website and facebook fan page as the promotion, reporting and socialize both in terms of reporting to support e-government and the most important is the focus in the field of environment, the conservation of nature, the introduction and utilization of research results and an introduction to the various types of Mountain crops to the public. In addition to the website and facebook fan page Bali Botanical Gardens also use TripAdvisor know the feedback from the community after a visit to the Bali Botanical Gardens.</p> Taufik Akbar ##submission.copyrightStatement## 2019-06-25 2019-06-25 2 1 21 25 10.31295/ijpm.v2n1.79 Classical mechanics for social benefit on catering food <p style="text-align: justify;">At this time a lot of people who want to create an event or activity is simple and efficient. For example, in terms of food preparation and dish. Usually, they prefer to order food rather than make your own by reasons of time and effort even though it is a little expensive. From this thought, we had the idea to create a food catering business. In starting a business in any field, then the first thing you should know is the market opportunity and how to rake in order. How is the market opportunity that we want to enter in our business and how to obtain the order? The second is that we must be able to analyze the strengths and weaknesses of our competitors and the extent of our ability to compete with them in terms of price, service, and quality. The third is mentally prepared and the courage to start. Get rid of the psychological barriers of shame, fear of failure and inner war between desire and doubt. Do not forget to be ready to face the risks, where business risk is a profit or loss. The greater, fortunately, it risks even greater. The important thing is brave to try and start. Better try but fail than fail to try.</p> Yoga Jihadkhan ##submission.copyrightStatement## 2019-06-25 2019-06-25 2 1 26 30 10.31295/ijpm.v2n1.80 Relativity method on online advertisement <p style="text-align: justify;">As world development increases, current market developments have led to strategies that must be implemented by companies in offering and marketing their products.

Research has been carried out on tsunami hazard level analysis based on scenario modeling and earthquake seismicity in southern Bali. This study uses earthquake data in January 2010 - July 2018. Tsunami prone areas in southern Bali are Klungkung district, Nusa Penida, Kuta beach, Sanur beach, Tabanan and Gianyar districts. The research conducted aims to determine the level of tsunami hazard by looking at the tsunami run up and arrival time in the southern region of Bali. This simulation model uses 1427 data which is then processed using Generic Mapping Tools (GMT) software so that seismicity maps are obtained, and tsunami modeling uses the Tsunami Observation and Simulation Terminal (TOAST) software. The results obtained from the tsunami modeling simulation in the form of altitude (run up) and tsunami wave arrival time (arrival time) which have an average value of 1,385 - 2,776 meters with an arrival time of 20-24 minutes. The tsunami hazard level is obtained in scenario A with a magnitude of 7.5 which has a maximum value of &lt;1 meter (low) and scenario B with a magnitude of 7.8 has a maximum tsunami run-up value of 1-3 meters (medium) and in scenario C with a magnitude 8.0 has a maximum run-up of tsunami waves of 1 - 3 meters (medium).</p> Fatmawati Fatmawati I Made Yuliara Ganis Riandhita Febriyanti Jia Kelo Audrey Vellicia Lintang Ardhana Reswari ##submission.copyrightStatement## 2019-07-05 2019-07-05 2 1 36 41 10.31295/ijpm.v2n1.88
