Judul: Rancang Bangun Perangkat Lunak Perencanaan Produksi Krisan Potong (Studi Kasus Di PT. Alam Indah Bungan Nusantara, Cianjur - Jawa Barat)
Abstrak: PT. Alam Indah Bunga Nusantara (PT.ABN) adalah produsen bunga krisan potong, krisan pot, anyelir potong, filler bunga (Caspea, Gypsophylla) dan filler daun (Asparagus Bintang, Philodendron Selloum). Produksi hanya mengandalkan perkiraan pasar yang belun jelas. Kerugian yang dialami apabila permintaan penjualan terdapat sisa barang produksi yang belum terjual sehingga mengakibatkan barang tidak dapat digunakan kembali. Hal ini dapat menyebabkan kerugian material, operasional dan tenaga kerja. Selain itu data mengenai permintaan penjualan kurang akurat sehingga kesulitan untuk merencanakan sebuah produksi tiap minggunya. Perencanaan produksi dapat diartikan sebagai proses pengambilan keputusan yang dapat dijadikan dasar untuk kegiatan ekonomis dan efektif pada masa yang akan datang. Pada proses ini diperlukan pemikiran meogenai aktifitas yang harus dikerjakan, bagaimana dan dimana suatu kegiatan akan dilakukan, serta siapa yang bertanggung jawab terhadap pelaksanaannya (Buffa dan Sarin, 1996). Sistem ini harus mendapat dukungan jaringan dan infrastruktur agar dapat dijalankan sehingga perlu dilakukan pengembangan sistem yang baru agar sesuai dengan pola yang ada. Pengelolaan sistem yang menganut metode System Development Life Cycle (SDLC) dibagi menjadi lima tahapan yaitu : (1) Investigasi, (2) Analisis, (3) Desain alternatif pemecahan masalah yang sesuai, (4) Implementasi atas solusi yang dibuat dan (5) Pemeliharaan dan pengembangan sistem. Penelitian ini bertujuan untuk merancang perangkat lunak (software) untuk kegiatan perencanaan produksi krisan potong dengan mengaplikasikan metode kuantitatif time series (moving average dan exponential smoothing) untuk teknik peramalan permintaan. Selain itu dapat mensimulasikan biaya total aktivitas produksi dalam satu greenhouse tunnels selama satu periode tanam dengan menggunakan simulasi Monte Carlo. Ruang lingkup penelitian ini meliputi analisa sistem perencanaan produksi krisan potong untuk satu periode tanam dalam greenhouse tipe tunnels. Rancang bangun perangkat lunak (software) perencanaan produksi krisan potong diberi nama SIMPro 1.0. Program SIMPro 1.0 merupakan program yang dapat membantu pihak manajemen dalam kegiatan perencanaan produksi krisan potong. Paket program SIMPro 1.0 dirancang dengan menggunakan Microsoft Access 2000 untuk menangani database, untuk bahasa pemogramannya menggunakan Visual Basic 6.0 dan XLSim 2.20 digunakan untuk membuat simulasi dengan menggunakan Monte Carlo. Paket program ini dirancang untuk memudahkan manager produksi dalam menangani database kegiatan produksi, mensimulasikan dan mengkomputasikan data yang ada melalui sistem manajemen yang terdapat dalam program ini. Database (basis data) yang terdapat dalam sistem ini meliputi data varietas, data lokasi dan data sarana produksi. Proses komputasi (perhitungan) dalam program SIMPro 1.0 ditampilkan pada menu basis model. Menu basis model terdiri dari form peramalan permintaan, form penjadwalan, form produksi untuk menghitung rencana kebutuhan produksi dan form biaya produksi yang harus dikeluarkan perusahaan.

Judul: Rancang Bangun Sistem Basis Data Produksi Krisan Potong PT Alam Indah Bunga Nusantara Cianjur, Jawa Barat, Indonesia.
Abstrak: PT Alam Indah Bunga Nusantara is a crysant cut flower company that have adequately big capacity production. In order to reach production target, PT ABN has sufficient infrastructure and production technology, i.e. green house with 6.03 ha of total productive area. The Operational production activity of crysant cut flower involves divisions of production system. That division are Mother Stock and Nursery (MSN), Production, Plant Disease (HPT), Technic, Store House, and Harvesting and Post Harvesting. All of these divisions interact each another for supporting production target. Thus, continuity and properness of data and information from all divisions have to be well proven. The problems appeared at the moment are semi manual and decentralized administration system of data and information. As a consequence, it is verily possible happened rate humans erros that cause inadequate operation control process. This decentralization of data make certain data and information only available on the certain division. Redudancy and inconsistency of data and information might occur on this condition. It might also cause divisions of production system no longer synergist. In oder to solve the problem, it was required to build database system of crysant cut flowers production (Simbapro Krisan Potong PT ABN). This system was built for modifying the manual and decentralized system become centralized and integrated system, then it will be able support the administration system of data and information of crysan cut flower production effective and efficient. The building method of this system was refered to SDLC (System Development Life Cycle) that consisted of five steps: investigation, analysis, design, implementation, and maintenance. The database system that had been built was desktop application and properly work on Ms Windows platform. It used Ms Acces 2007 and Visual Basic vii 6.0 (VB). Microssoft Acces 2007 (RDBMS) was used on building relational database and vb was used on building application interface. The former prototype of Simbapro Krisan Potong PT ABN had been built base on advisement of functional requirement that covered input master data form, operational data form, information form, and reports. Simbapro Krisan Potong PT ABN serves information inter divisions and centrally provided, thus expectedly able to integrate data and information of crysant cut flower production that suitable with each divisions need. This system only covered several functional aspect, i.e.: documentational master and operational production data, inventory information of crysant plant (mother, seed, plant), information of the plant desease, and information of operational production. So, this system could be improved as well as. The maintenance of system, as finally step of SDLC, was executed at 11 february 2010. User that evaluate the system was Mr.Tatan Supriatna (as crysant an expert). It resulted response on operational method, suggestion on information detail, and readiness on report completeness. Based on user response on operational aspect, this system was user friendly; on problem limitation aspect, the information service was adequately sufficient. However, this system still need to be improved during implementation. Meanwhile, on report aspect, the system was necessary to be completed.

Judul: Durability of Specific Immunoglobulin (Ig) Y Againts Influenza and Covid-19 in Sunscreen
Abstrak: The benefit of specific immunoglobulin Y (Ig Y) as an active ingredient in personal care products such as sunscreen has not been properly studied. Our study aims to evaluate the reliability of specific IgY against influenza and the COVID-19 virus in a sample sunscreen product. Specific IgY influenza and COVID-19 viruses were inserted in the sample sunscreen at two concentrations of 0.1% and 0.25%. Three treatments were observed: control (C) sunscreen without IgY, treatment 1 (T1) sunscreen with 0.1% IgY, and treatment 2 (T2) sunscreen with 0.25% IgY. Organoleptic observations were carried out to monitor changes in aroma, color, and texture, and sunscreen sampling was done every week for 6 weeks. The durability of IgY was evaluated using an enzyme-linked immunosorbent assay (ELISA) and a neutralization assay. Organoleptic observation from weeks 1 to 6 showed consistency in its aroma, color, and texture. Enzyme-linked immunosorbent assay and neutralization assay (NA) results of the T1 and T2 groups showed negative results except for sample T1 at week 5, which showed a positive result in the Influenza A ELISA. Based on the results, it seems that IgY concentrations of 0.1% or 0.25% were not optimal. However, this negative result might be due to low concentration of the IgY and the presence of beeswax, which inhibits IgY and causes it to dissolve in distilled water, thus preventing it from being detected in the assay.
