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: Studi Taksonomi Katak Subgenus Papurana (Lesson, 1831) dari Halmahera (Anura, Ranidae, Hylarana), Studi Taksonomi Katak Subgenus Papurana (Lesson, 1831) dari Halmahera (Anura, Ranidae, Hylarana
Abstrak: I reevaluated taxonomic of subgenus Papurana position from Halmahera based on morphological and molecular analyses. My results show that two separate species occur on the Halmahera Island, each nested within two distinct clades (hereafter papua clade and celebensis clade), one of which corresponds to H. moluccana (celebensis clade) and the other to an unidentified species (papua clade). By p-distance ranging from 6.9 to 11.5% on the 16S rRNA gene, the unidentified species (Hylarana sp.) is genetically different from all congeners of the papua clade. The Hylarana sp. can be distinguished from all congeners by following combination of charactes: vomer teeth in two oblique rows with narrow inter-vomer distance; snout rounded dorsally; dorsum with few scattered cone-shaped tubercles that are black with white tips; distinct skin folds (ridges) on the dorsal side of the thigh coinciding with dark brown cross bars; a marbled pattern on the ventral side of the thigh and yellowish groin. I also present new data for H. daemeli, H. volkerjane, and H. arfaki from the western region of Papua. Furthermore, I found that H. celebensis has numerous mtDNA lineages, indicating cryptic diversity within the celebensis clade. The discovery of two separate species on Halmahera necessitates more research into the biogeographic history of Hylarana in Northern Moluccas.
