Judul: Pengembangan Sistem Informasi untuk Pengaplikasian Penelusuran Balik pada Barang Reject
Abstrak: Dalam suatu industri, data dan informasi tentang asal-usul suatu produk merupakan alat yang penting dalam pengambilan keputusan. Untuk mendapatkan data tersebut diperlukan sistem penelusuran balik dari bahan baku sampai produk jadi. Perusahaan XYZ merupakan perusahaan pintu kayu yang memiliki sistem pencatatan data berbasis digital namun proses penelusuran produk yang reject masih perlu dilakukan secara manual. Sistem traceabiliy dibangun dengan pencatatan kode packing dari setiap produk yang diproduksi setiap mesin. Data yang dihasilkan dari beberapa lini produksi dikumpulkan dan diolah dalam suatu Database Management System (DBMS), sehingga hubungan data antarlini dapat ditentukan. Pembuatan dashboard kemudian dilakukan agar data yang telah diolah dapat dimengerti. Dalam penelitian ini juga dilakukan pembuatan format pengisian data dengan hasil berupa form pengisian data yang mudah diisi dan tersambung dengan database sehingga data dapat tersusun secara rapi. Penelitian ini diharapkan dapat dimanfaatkan oleh perusahaan untuk mempermudah pemahaman tentang asal-usul dari barang yang reject, dan juga dapat bermafaat untuk kolektor data dalam pengisian data.

Judul: Design of Production Management Information System in Furniture Company
Abstrak: Jepara merupakan pusat produsen berbagai produk mebel kayu di Indonesia. Dalam proses produksi, pendataan produksi mebel masih menggunakan metode konvensional. Selain itu, monitoring kemajuan proses produksi juga tidak dapat dilakukan secara detail. Diperlukan sebuah sistem yang dapat melakukan pendataan terhadap proses produksi mebel yang terintegrasi, cepat, dan mudah. Penelitian ini bertujuan untuk membangun sistem informasi manajemen produksi yang dapat diakses melalui website. Sistem juga diharapkan dapat melakukan pendataan dan monitoring secara terintegrasi pada produksi mebel pada perusahaan. Metode penelitian mengacu pada metode System Development Life Cycle (SDLC) yang terdiri dari investigasi sistem, analisis sistem, desain sistem, implementasi, pemeliharaan, dan evaluasi. Hasil penelitian adalah sebuah website yang dapat melakukan pendataan dan monitoring di PT Talenta Java Design. Berdasarkan pengujian lapangan yang dilakukan oleh setiap bagian produksi, didapatkan hasil bahwa sistem dinilai “Sangat Baik” dengan nilai user acceptance test sebesar 95.71%., Jepara is a center for producing various wooden furniture products in Indonesia. At production process, data collection still using conventional method. Monitoring the progress of the production process cannot be carried out in detail. A system is needed that can collect data on the furniture production process easily, faster, and integrated. This study aims to build a production management information system that can be accessed through website. The system is also expected to be able carry out integrated data collection and monitoring on furniture production at the company. The research method refers to System Development Life Cycle (SDLC) method which consists of system investigation, system analysis, system design, implementation, maintenance, dan evaluation. The result of the research is a website that can perform data collection and monitoring at PT Talenta Java Design. Based on test by each production department, the system was considered “Very Good” with user acceptance test value of 95.71%.

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.
