Pengambilan data dilakukan melalui pengisian kuesioner dan indepth interview secara online. Permasalahan konsumen dalam diet adalah masih banyaknya pola makan yang tidak teratur, kualitas makanan yang kurang baik, dan defisit nutrisi. Value yang ditawarkan adalah kustomisasi menu, info tentang susunan menu dengan kandungan gizi, dan harga terjangkau. Konsumen dari bisnis ini adalah orang-orang yang berusia 19-24 tahun, berniat melakukan diet, serta peduli dengan nutrisi yang dikonsumsi. Revenue bisnis ini berasal dari sistem berlangganan. Bisnis ditawarkan melalui channel gerai online dan offline serta melalui reseller. Prototype katering “Yuk Sehat” berupa susunan menu selama 15 hari., The highest health problem in the adult age group in Indonesia is obesity which is closely related to diet. The purpose of this study is to analyze consumer problems in diet, design a business prototype "Yuk Sehat" and design a verified business model for catering "Yuk Sehat". Data were collected through filling out online questionnaires and in-depth interviews. Consumen problems in diet are there are still many irregular eating patterns, poor food quality, and nutritional deficits. The value offered is the menu customization, info on menu composition with nutritional content, and affordable prices. Consumers of this business are people aged 19-24 years, interested to do a diet and care about the nutrients they consume. This business revenue comes from the subscription system. Business is offered through online and offline outlet channels as well as through resellers. The "Yuk Sehat" catering prototype is a menu arrangement for 15 days.

Judul: Needietary: Aplikasi Penyedia Kebutuhan Diet
Abstrak: Sejalan dengan pertumbuhan ekonomi, jumlah penduduk yang tergolong berat badan berlebih dan obesitas mengalami peningkatan. Hal ini mendorong meningkatnya kebutuhan akan program diet untuk mengatasi masalah berat badan lebih dan obesitas. Dalam melakukan program diet untuk menurunkan berat badan, seseorang sering kali menghadapi kendala dan permasalahan, sehingga perlu aplikasi untuk membantu pelaksanaan program dietnya. Penelitian ini bertujuan untuk (1) mengidentifikasi permasalahan yang dialami kosumen saat melakukan diet, (2) merancang prototype aplikasi diet yang dapat menjadi solusi bagi permasalahan konsumen saat melakukan diet, (3) menyusun model bisnis aplikasi diet yang tepat untuk untuk memecahkan permasalahan saat melakukan diet. Metode yang digunakan dalam penelitian ini adalah customer development yang berfokus pada tahapan customer discovery. Pengambilan sampel dilakukan dengan purposive sampling sebanyak 30 responden di daerah Jakarta. Hasil pada penelitian ini menunjukkan bahwa terdapat beberapa permasalahan saat menjalani diet dengan dua permasalahan tertinggi yaitu kesulitan menentukan menu diet dan bosan dengan menu makanan diet. Berdasarkan permasalahan yang diperoleh berdasarkan informasi diperoleh dari responden, disusun prototype aplikasi Needietary yang dirancang untuk mengatasi permasalahan pelaku diet. Hasil penelitian lainnya adalah teridentifikasinya dan terverifikasinya kanvas model bisnis dalam mengembangkan aplikasi ini sebagai suatu bisnis. Pada penelitian selanjutnya disarankan untuk melanjutkan penelitian ketahapan customer validation., In line with economic growth, the number of people classified as overweight and obese has increased. This has led to an increasing need for diet programs to address the problem of overweight and obesity. In doing a diet program to lose weight, a person often faces obstacles and problems, so an application is needed to help implement the diet program. This study aims to (1) identify the problems experienced by consumers while on a diet, (2) design a diet application prototype that can be a solution to consumer problems when dieting, (3) develop the right diet application business model to solve problems when doing a diet. The method used in this research is customer development which focuses on the customer discovery stage. Sampling was done by purposive sampling of as many as 30 respondents in the Jakarta area. The results of this study indicate that there are several problems when undergoing a diet with the two highest problems, namely difficulty in determining diet menus and boredom with diet food menus. Based on the problems obtained based on the information obtained from the respondents, a Needietary application prototype was developed which was designed to overcome the problems of dieters. Another research result is the identification and verification of the business model canvas in developing this application as business. In further research, it is recommended continuing research on customer validation stages.

Judul: Thermal Characteristics and Dynamics of Tropical Cyclone over Western North Pacific Ocean: A Case Study of Typhoon Songda (Chedeng) 2011
Abstrak: The frequent occasion of Tropical Cyclone (TC) over Western North Pacific (WNP) Ocean lies from 10˚N to 26˚N and 121˚E to 170˚E. Sources of TC development come from warm ocean temperature where latent heat is released during condensation processes and subsequently concentrated in the boundary layer. Relative humidity at 850-700 hPa is responsible to produce the most intense storm. Meanwhile, weak vertical wind shear between 850-200 hPa is one of the dynamical factors that lead to the development of TC. Pressure level of 850-200 hPa is chosen to minimize the thermodynamic effect in the lower troposphere. Typhoon Songda (Chedeng in the Philippines) or TSC lasted from May 18th to 30th, 2011 and strengthened into powerful Super Typhoon stage between May 24th and 27th. Long curving track and the exhibition of all sequences of TC life cycle, TSC is then considered as an ideal case of TC. The objective of the study with case of TSC is to investigate the role of thermal characteristics and dynamics on TC intensity. The research is carried out by using Advanced Research of Weather Research and Forecasting model (WRF ARW model) version 3.3. Two domains are employed in the model. The first domain situate from 02˚N to 40˚N and 118˚E to 149˚E and cover spatial resolution () of 33.1 km. The second domain situate from 09˚N to 27˚N and 119˚E to 132˚E with of 11 km. Timestep of the model () is 120 seconds. The model is supported by the following physical parameterization, i.e., Yonsei University Scheme (YSU) in the boundary layer, Kain-Fritsch scheme (KF) in the cumulus, and WRF Single-Moment 3-class scheme in the microphysics. Initial meteorological condition prior to the formation of the cyclone is generated using WRF ARW standard-release model. Sensitivity of the model output is obtained from a selected single-parameter change scenarios, namely, 10 % to 20 % decrease and increase of wind shear initial data at 850-200 hPa, and by 10 % to 20 % decrease of relative humidity initial data at 850-700 hPa. The result showed that the negative correlations between wind shear and intensity are found in wind shear scenarios. Wind shears of 10 ms-1 which lead to strengthening of the wind intensity in the early period of Typhoon development are found in wind shear scenarios. The effect of wind shear changes on wind intensity is statistically significant in the 20 % wind shear scenarios. During mature stage, weak wind intensity occurred when wind shear increase as given in the WRF standard-release and the 20 % decreasing scenario. Different situation is found in the 20 % increasing scenario where wind shear tend to weak and lead to strong wind intensity at this stage. Meanwhile, the reduction of moisture supply at 850-700 hPa resulting from 20 % decreasing relative humidity play a major role in the weakening of wind intensity and reduces mechanical energy of the cycle process as much as 300 J kg-1.
