Judul: Pengaruh relabeling rak penyimpanan terhadap waktu pencarian produk olahan hasil ternak
Abstrak: Retail saat ini menjadi salah satu penyumbang perputaran ekonomi di Indonesia. Permintaan pelanggan terkait barang dalam jumlah tertentu berkesinambungan dengan waktu pencarian barang di backroom. Hal ini menimbulkan permasalahan krusial jika penempatan barang dagang yang disimpan di backroom masih belum teratur sehingga menyebabkan ketidakefisienan kerja. Penyusunan ulang barang dagang di backroom menjadi per kategori dan per brand bertujuan untuk mempermudah penempatan dan pengambilan barang dagang sehingga mengurangi waktu pencarian barang. Hasil penelitian menunjukan adanya pengaruh signifikan terhadap penyusunan ulang barang dagang di backroom dengan relabeling rak penyimpanan. Terdapat perbedaan waktu selama 27 menit yang menghasilkan efisiensi dalam pencarian barang setelah arrangement. Penilaian konsistensi perlu dilaksanakan minimal satu kali seminggu., Retail is currently one of the contributors to economic turnaround in Indonesia. Customer demand related to products in a certain quantity are continuous with the time to search for products in the backroom. This creates a crucial problem if the placement of products in the backroom is still uncoordinated, it can cause work inefficiency. Rearranging products in the backroom into per-brand categories aims to make it easier to place and retrieve products in the backroom area also minimizing time searching for goods. The results showed a significant effect on the rearrangement of trade goods in the backroom by relabeling storage shelves. There is a time difference of 27 minutes which results in efficiency in searching for goods after arrangement. Consistency assessment needs to be carried out at least once a week.

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: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
