Judul: Optimization of Facility Layout Systems,  Display, and Inventory Management at Meatly Shop Sijamal Corporation
Abstrak: Meatly Toko Daging memerlukan standar sistem untuk menjamin kualitas produk dan kepuasan konsumen dalam menjalankan bisnis frozen food. Namun, Meatly masih menghadapi masalah dalam optimasi tata letak fasilitas, tata letak display, dan peramalan penjualan produk. Tujuan penelitian ini adalah memberikan rekomendasi perbaikan menggunakan metode Systematic Layout Planning (SLP) dengan algoritma Computerized Relationship Layout Planning (CORELAP), Blocplan, dan kecerdasan buatan (Artificial Intellegent) untuk tata letak fasilitas. Tata letak display dioptimalkan dengan Market Basket Analysis (MBA), dan peramalan penjualan menggunakan Double Exponential Smoothing. Berdasarkan hasil optimasi sistem, terdapat peningkatan efisiensi penggunaan lahan sebesar 9,62% dan penurunan jarak perpindahan sebesar 7,55%. Pada tata letak display, dilakukan tiga perubahan letak kategori produk. Sedangkan untuk peramalan, didapatkan rekomendasi metode yang tepat dan akurat., Meatly Meat Shop requires a standard system to guarantee product quality and consumer satisfaction when running a frozen food business. However, Meatly still faces problems in optimizing facility layout, display layout, and product sales forecasting. This research aims to provide recommendations for improvements using the Systematic Layout Planning (SLP) method with the Computerized Relationship Layout Planning (CORELAP), Blocplan, and artificial intelligence algorithms for facility layout. The display layout is optimized using Market Basket Analysis (MBA), and sales forecasting uses Double Exponential Smoothing. Based on the system optimization results, there was an increase in land use efficiency by 9.62% and a decrease in movement distance by 7.55%. In the display layout, three changes were made to the location of product categories. Meanwhile, recommendations for appropriate and accurate methods were obtained for forecasting.

Judul: Production Facility Layout Design at PT Sutan Vet Medika
Abstrak: PT Sutan Vet Medika merupakan industri pakan hewan yang memproduksi suplemen penambah nafsu makan kucing dan anjing. Terdapat beberapa permasalahan pada tata letak fasilitas produksi yaitu penempatan pintu toilet yang belum sesuai dengan pedoman CPOHB, penempatan tata letak fasilitas produksi belum memperhatikan aliran bahan sehingga terdapat aliran bahan yang backtracking, dan penggunaan area ruangan fasilitas produksi yang digunakan sebagai tempat tinggal karyawan. Proyek desain utama ini bertujuan untuk merancang alternatif tata letak fasilitas produksi untuk memperbaiki permasalahan dari tata letak sebelumnya. Perancangan perbaikan tata letak fasilitas produksi dilakukan dengan metode SLP (Systematic Layout Planning) dan algoritma CORELAP (Computerized Layout Planning). Tata letak usulan fasilitas produksi menghasilkan peningkatan efisiensi jarak perpindahan material sebesar 23,67% berdasarkan hasil simulasi., PT Sutan Vet Medika is an animal feed industry that produces supplements to increase the appetite of cats and dogs. There are several issues with the production facilities layout, including the improper placement of the restroom door according to the Good Animal Drug Manufacturing Practice (GADMP) guidelines, the production facilities layout that have not paid attention to the material flow as it creates material backtracking, and the use of production facilities space for employees’ residences. This research aims to design alternative production facilities layouts to address the issues of the previous layout. The improvement of the production facilities layout is carried out using the Systematic Layout Planning (SLP) method and the CORELAP (Computerized Layout Planning) algorithm. The layout of proposed production facilities increase 23.67% material transfer distance efficiency based on simulation results.

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.
