Judul: Design of an Android-Based Beef Traceability System Using QR Code
Abstrak: Daging sapi merupakan makanan yang sangat digemari di Indonesia. Namun ada beberapa aktor yang menyebabkan kelangkaan daging sapi yang beredar di pasaran sehingga menyebabkan kenaikan harga pada daging sapi. Ada juga aktor yang mencampur daging sapi dengan daging asing yang tidak layak dimakan. Oleh karena itu, dibutuhkan suatu sistem yang dapat melacak dan menyimpan seluruh data dan riwayat dari rantai pasok daging sapi. Penelitian ini bertujuan membuat rancang bangun sistem ketertelusuran rantai pasok daging sapi berbasis android menggunakan QR Code untuk mencegah malapraktik dalam rantai pasok daging sapi dan menjamin asal-usul daging sapi. Sistem ini diberi nama SmartMoo. Target pengguna sistem adalah aktor-aktor penting dalam rantai pasok daging sapi, meliputi peternakan sapi, feedlot, Rumah Potong Hewan (RPH) dan pasar. Investigasi dilakukan untuk mengetahui data apa saja yang diperlukan dalam sistem yang akan dibuat, dari data tersebut bisa disusun rancangan fungsional dan rancangan struktural. Setelah itu dibuat desain tampilan yang akan ditampilkan pada layar antarmuka pengguna (user interface). Selanjutnya tahapan kodifikasi aplikasi, setelah kodifikasi dilakukan pengujian sistem. SmartMoo sudah berhasil dibuat dengan Android Studio menggunakan layanan Firebase sebagai tempat penyimpanan datanya. Setelah sistem dibuat, dilakukan pengujian terhadap penggunaan aplikasi. Pengujian aplikasi terdapat tiga kategori, yaitu: desain, informasi dan aplikasi. Nilai likert kategori desain adalah 79,71% dan untuk kategori informasi dan aplikasi memiliki nilai yang sama, yaitu 87,5%. Data sudah bisa disimpan di Firebase dan fungsi untuk membuat QR Code sudah berhasil dibuat. Setelah QR Code terpindai, sistem sudah menampilkan data yang sesuai. Tahap pengujian menunjukkan bahwa SmartMoo harus terimplementasikan namun perlu banyak pengembangan dalam segi desain dan fungsi dari sistem., Beef is a food material that is very popular in Indonesia. However, there are several actors who have caused the scarcity of beef on the market, causing an increase in the price of beef. There are also actors who mix beef with foreign meat that is not edible. Therefore, a system that can track and/or store all data and history from the beef supply chain is needed. This study aims to design an Android-based beef supply chain traceability system using a QR Code to prevent malpractice in the beef supply chain and guarantee the origin of beef. This System is named SmartMoo. The target users are important actors in the beef supply chain, those are cattle farms, feedlot, slaughterhouses and beef market players. Investigations were carried out to find out what data needs to be included in the system to be created, from this data a functional design and structural design can be compiled. After that, the display which will be displayed on the user interface screen was designed, followed with application codification stage. The final stage was the system testing. There are three categories of application testing, namely: design, information and application. SmartMoo has been successfully created with Android Studio using the Firebase service as the data repository. The Likert value for the design category is 79.71% and for the information and application categories it has the same value, which is 87.5%. The data can be saved in Firebase and the function to create the QR Code has been successfully created. After

Judul: Rancang Bangun Aplikasi Pendataan Ternak Sapi Potong Menggunakan RFID Berbasis Android
Abstrak: Usaha peternakan sapi potong terbagi atas dua sektor, yaitu usaha ternak sapi potong rakyat dan perusahaan. Sebagian besar peternakan sapi potong di Indonesia merupakan peternakan rakyat. Pola pemeliharaannya masih tradisional, serta kepemilikan jumlah ternak yang terbilang masih sedikit antara 2-3 ekor/peternak. Karena kurangnya pengawasan dan kontrol terhadap ternak, standar mutu hasil ternak menjadi salah satu permasalahan yang mempersempit lingkup pasar dari usaha ternak sapi potong rakyat. Penelitian ini bertujuan untuk merancang dan membangun aplikasi berbasis Android yang dapat dipergunakan untuk membantu para peternak tradisional untuk mencatat dan mengakses data ternak sapi potong. Pendekatan dalam tahap perancangan aplikasi menggunakan metode pengembangan System Development Life Cycle (SDLC) yang terdiri dari investigasi sistem, analisis sistem, desain sistem aplikasi, implementasi sistem aplikasi, dan pemeliharaan sistem aplikasi. Hasil dari penelitian ini adalah aplikasi yang dapat mencatat dan menyajikan data ternak sapi potong sesuai dengan EPC pada label RFID yang dimiliki., The beef cattle farming business is divided into two sectors, namely the small-scale farmers and companies. The majority of beef cattle farming in Indonesia is carried out by small-scale farmers, with traditional breeding methods and a small number of cattle per farmer, usually between 2-3 heads of cattle. Due to the lack of supervision and control over the cattle, the quality standards of the cattle become one of the problems that narrow the market scope of small-scale beef cattle farming. This research aims to design and build an Android-based application that can be used to help traditional farmers record and access data on beef cattle. The approach in the application design phase uses the System Development Life Cycle (SDLC) method, which consists of system investigation, system analysis, application system design, implementation of the application system, and maintenance of the application system. The result of this research is an application that can record and present data on beef cattle according to the Electronic Product Code (EPC) on the RFID tag that the cattle have.

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.
