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: Re-Designing The Retail Business Warehouse Layout Using Dedicated Storage, Shared Storage, and The Pareto Effect Method
Abstrak: Manajemen pergudangan adalah hal yang penting bagi suatu bisnis salah satunya yaitu bisnis ritel. PT AEON Indonesia adalah salah satu perusahaan ritel yang sedang berkembang pesat di Indonesia. Sistem tata letak gudang yang diterapkan pada PT AEON Indonesia hanya menggunakan metode dedicated storage dengan jenis penyimpanan rak. Namun, peletakan produk belum sesuai pengkategorian yang tertera dan beberapa shelving masih terlihat kosong yang membuat gudang menjadi tidak rapi. Penelitian dilakukan di backroom milk, baby food, dan baby needs PT AEON Indonesia Cabang Sentul pada bulan Februari 2023 hingga Juni 2023. Penelitian ini bertujuan untuk memberikan rekomendasi tata letak gudang yang lebih efektif dan efisien dilihat dari penggunaan ruang serta total jarak tempuh produk. Tata letak gudang baru disusun menggunakan gabungan metode dedicated storage, shared storage, dan metode pareto effect. Tata letak gudang baru mampu mereduksi total jarak tempuh keseluruhan produk sebesar 21,5% dan mengoptimalkan penggunaan ruang sehingga terdapat ruang yang dapat digunakan untuk mengaktualisasikan shelving simpan barang recekan dan temporary area., Warehousing management is important for a business, one of which is a retail business. PT AEON Indonesia is a fast-growing retail company in Indonesia. The warehouse layout system implemented at PT AEON Indonesia only uses the dedicated storage method with the rack storage type. However, product placement is not in accordance with the categorization listed and several shelves still look empty, making the warehouse untidy. The research was conducted at backroom milk, baby food, and baby needs PT AEON Indonesia Sentul branch from February 2023 to June 2023. This study aims to provide recommendations for warehouse layouts that are more effective and efficient in terms of space usage and the total mileage of products. The new warehouse layout was prepared using a combination of several methods, namely the dedicated storage method, shared storage, and the pareto effect method. The new warehouse layout is able to reduce the total mileage of all products by 21.5% and optimize the use of space so that there are spaces to realize recekan shelves and temporary areas.

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.
