Judul: Pengembangan Sistem Informasi Pelaporan dan Pemantauan Produksi Gula Berbasis Android.
Abstrak: Gula pasir adalah salah satu bahan pemanis alami yang berasal dari tanaman tebu. Menurunnya produksi gula terjadi karena inefisiensi pabrik gula pada proses produksi. Hal tersebut menyebabkan banyak pabrik gula yang ditutup karena secara ekonomis tidak menguntungkan. Salah satu upaya untuk meningkatkan efisiensi pabrik gula, perlu adanya sistem informasi pelaporan dan pemantauan proses produksi yang dapat digunakan untuk mengetahui keadaan proses pengolahan tebu menjadi gula agar dapat diatur sesuai pada kondisi optimal. Tujuan dari penelitian ini adalah merancang sistem informasi untuk melakukan proses pelaporan hasil analisis dari setiap stasiun produksi yang berada di pabrik gula. Penelitian ini dilakukan dengan metode pendekatan sistem yang terdiri identifikasi masalah, analisis kebutuhan sistem, perancangan sistem, dan pengujian. Hasil dari penelitian ini adalah sebuah aplikasi android dan laman website yang dapat diakses untuk melakukan penginputan data pengawasan proses produksi. Berdasarkan pengujian langsung yang dilakukan oleh pekerja pabrik gula didapatkan hasil semua pekerja setuju bahwa sistem informasi mempermudah pelaporan proses produksi gula.

Judul: Android Based Sugarcane Cultivation Information System Design
Abstrak: Gula merupakan salah satu bahan pokok yang memiliki tingkat kebutuhan tinggi di Indonesia. Ketersediaan gula di Indonesia belum mencukupi kebutuhan nasional. Salah satu bahan pembuatan gula adalah tebu. Produksi tebu sebagai bahan pembuatan gula yang maksimal pada tingkat desa dapat membantu pemerintah dalam memenuhi kebutuhan gula nasional. Produksi tebu yang maksimal dapat dipenuhi dengan melakukan manajemen data lahan tebu pada tingkat desa. Penelitian ini bertujuan untuk merancang sistem informasi berbasis android pada budidaya tebu tingkat desa yang dapat memaksimalkan manajemen data lahan tebu. Tahapan penelitian ini terdiri dari identifikasi masalah, analisis sistem, desain sistem, implementasi sistem, dan pengujian sistem. Penyususnan basis data menggunakan bahasa pemrograman terstruktur pada webhost untuk menyusun basis data, relasi antar data, dan akses pengguna. Sistem informasi budidaya tanaman tebu berbasis android telah diimplementasikan berbasis android dan telah diuji sistem. Berdasarkan uji sitem aplikasi ini dapat menampilkan informasi berupa data pengguna, data lahan, data pengolahan lahan, data pemupukan, data panen, dan data penjualan bekerja dengan baik., Sugar is a staple that has a high level of need in Indonesia. The availability of sugar in Indonesia is not sufficient for national needs. One of the ingredients for making sugar is sugar cane. Sugar cane production as a material for making maximum sugar at the village level can assist the government in meeting national sugar needs. Maximum sugarcane production can be met by managing data on sugarcane fields at the village level. This study aims to design an Android-based information system for sugarcane cultivation at the village level that can maximize sugarcane land data management. The stages of this research consist of problem identification, system analysis, system design, system implementation, and system testing. Database development uses structured query language on the webhost to compile databases, relationships between data, and user access. An Android-based information system for sugar cane cultivation has been implemented based on Android and the system has been tested. Based on the system test, this application can display information in the form of user data, land data, land processing data, fertilization data, harvest data, and sales data.

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.
