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: Design of Layout Improvement in Food Canning Factory Sharing
Abstrak: PT Kita Satu Rasa sebagai suatu factory sharing memiliki tantangan untuk menyediakan produk pangan yang berkualitas melalui proses produksi yang lancar, aman, dan bermutu. Namun, dalam pengamatan langsung masih ditemukan permasalahan utamanya pada kondisi tata letak yang dapat memengaruhi kelancaran proses produksi. Permasalahan yang dihadapi PT Kita Satu Rasa pada tata letak pabrik pengalengan saat ini yaitu penempatan aktivitas yang terpencar, aliran backtracking, dan ketidaksesuaian allowance pada area kerja. Penelitian ini bertujuan mengidentifikasi kondisi awal tata letak pabrik pengalengan dan menganalisis perbaikan tata letak pabrik pengalengan. Perancangan perbaikan tata letak dilakukan dengan metode SLP (Systematic Layout Planning) dan algoritma CORELAP (Computerized Layout Planning). Tata letak usulan pada pabrik pengalengan menghasilkan peningkatan efisiensi jarak perpindahan material sebesar 28,89% berdasarkan hasil simulasi., PT Kita Satu Rasa, as a sharing factory, has challenges providing quality food products through a safe and quality production process. The problems PT Kita Satu Rasa faced in the current layout of the canning factory are the placement of scattered activities, backtracking flow, and inappropriate allowances in the work area. However, in direct observation, the main problem is still found in the layout conditions that will affect the safety and quality of the final product. This study aims to identify the initial conditions and analyze the improvement of the cannery layout. The layout improvement design uses the SLP (Systematic Layout Planning) method and the CORELAP (Computerized Layout Planning) algorithm. The proposed layout of the cannery increased the efficiency of the material transfer distance by 28.89%, based on the 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.
