Abstract

Permasalahan yang dialami perusahaan yaitu mengenai penentuan jumlah pemesanan bahan baku. Terkadang perusahaan mengalami kesulitan dalam menentukan pembelian bahan baku untuk persediaan di gudang, Dampak yang dapat ditimbulkan yaitu akan menambah beban biaya persediaan bagi perusahaan serta kekurangan bahan baku ketika permintaan produk sedang tinggi. Untuk menyelesaikan permasalahan tersebut maka diperlukan suatu metode EOQ (economic order quantity) yang digunakan untuk mengetahui pembelian yang tepat bagi perusahaan. Tujuan dari penelitian yaitu mengetahui persediaan bahan baku dengan metode EOQ, mengetahui Total Inventory Cost secara keseluruhan dan membuat peramalan permintaan bahan baku untuk tahun berikutnya. Berdasarkan perhitungan dengan metode EOQ maka jumlah pembelian resin yang paling optimal dengan kondisi pemesanan bersyarat yaitu untuk lot order kapasitas truk pengirim resin sebanyak 285,000 kg (19 truk sedang) untuk tahun 2014, dan untuk tahun 2015 sebesar 270,000 kg (18 truk sedang). Total jumlah biaya dengan metode EOQ sebesar Rp. 19.680.000 sedangkan jumlah biaya persediaan dengan metode perusahaan sebesar Rp. 46.488.752 selama tahun 2014-2015. Penghematan yang dapat dilakukan dari total biaya persediaan oleh PT XYZ jika menggunakan metode Economic Order Quantity sebesar 57,66%. Berdasarkan pola data pemesanan yang didapat maka metode peramalan yang sesuai adalah metode regresi linier maka didapat total peramalan resin untuk tahun 2016 sebesar 665,788 kg dengan rata-rata pemakaian perbulan sebesar 55,48233 kg.

Abstract

The development of multifunctional drinking bottles as well as tissue storage is one of the needs and desires of customers. This product requires further analysis of what costs are used through the calculation of cost estimates. The system development in this study applies the full costing method. The use of this full costing method works by calculating the overall cost of product development through the calculation of the cost of production, selling price and break-even point obtained from collecting data on labor costs, raw materials, factory overhead, production quantities and selling prices. The results of this study obtained the total cost of raw materials for a period of 1 month with a total of Rp. 243.250.000,-, the cost of production with the amount of Rp. 260,462,247,-, the selling price per unit is Rp. 104,184.90, - with a profit of 30%, namely Rp. 78,138,674 and the break-even point of Rp. 372.626.70,- and 1904 units of multifunctional drinking bottle products as well as tissue storage.

Abstract

Perkembangan teknologi informasi membuat perilaku masyarakat disemua kegiatan yang biasa dilakukan perseorangan atau suatu lembaga. Masyarakat sekarang sangat memerlukan bantuan perangkat dalam bentuk digital, ketergantungan ini akibat aspek kehidupan yang semakin komplek. Aspek kehidupan ini mengharuskan semua kegiatan dilakukan secara cepat serta efektif dan efisien. Salah satu kebutuhan bagi masyarakat adalah tempat tinggal apalagi bagi pendatang disuatu tempat sepeti masyarakat daerah yang menuntut ilmu di perkotaan. Sepertihalnya mahasiswa baru dari daerah pasti memerlukan tempat tinggal selama waktu mengikuti pendidikan di suatu perguruan tinggi. Universitas Gunadarma adalah salah satu kampus yang memiliki mahasiswa yang dating dari semua daerah Indonesia ada juga dari luar negeri. Kebutuhan informasi tempat tinggal tersebut dapat dibantu dengan Sistem Informamasi Geografis dalam peneltian ini menggunakan metode formula haversine. Calon mahasiswa baru dapat dengan mudah menemukan tempat tinggal atau kosan sesuai dengan kebutuhan. Sistem Informasi ini juga membantu para pemilik kost menginformasikan secara luas usaha penyewaan tempat kost mereka. Penelitian ini menerapkan model deskriptif kualitatif yaitu analisa data berdasarkan hasil wawancara, observasi dan survey lapangan. Sistem Informasi pada penelitian ini dirancang dengan bahasa pemrograman PHP dan MySQL. Penelitian berhasil menghasilkan sistem informasi geografis dengan menampilkan lokasi kosan berbentuk peta yang disediakan oleh perusahaan Google

Abstract

Mpok Imeh Chips is an Independent small business that produces Balado cassava chips in Jakarta, where cassava chips are packaged using plain plastic so that it has an unattractive impression. This research focuses on developing packaging designs that are following customer desires using the quality function deployment (QFD) method. Based on the results of the study, it is known that the customer's requirement for cassava chip packaging produced by UKM Mpok Imah includes cassava chip packaging that functions to protect the product, a medium packaging size. The form packaging is a standing pouch. Cassava chips packaging is made of polypropylene plastic transparent packaging. There is product information on the packaging. The packaging design is based on the house of quality (HOQ) in QFD and uses polypropylene plastic materials, size (14 x 22) cm, a weight of 250 grams, cassava chips illustration, transparent and a standing pouch packing, description on the label shown on the front view design shows a visualization of the chip's packaging, there is some information about the product including the product name, net weight, address of the producing party and the halal logo. On the back packaging shown, there is information about the composition, storage rules and how used the packaging information expiration date of the packaged product.

Abstract

This study discusses one of the cinemas in the city of Depok, West Java where the object of research is cinema seats. Adding RFID (Radio Frequency Identification), so you don't know the cost budget and time to accelerate project completion using the CPM method to solve problems. CPM (Critical Path Method) is an analytical technique for planning, scheduling and project control using the critical path method with a single estimate for the duration of an activity. The results of the study using the CPM method produced a budget of IDR 2,580,000 million for normal costs using normal time, while for costs that were accelerated by carrying out the analysis phase to speed up project time, it was IDR 2,890,000 million. The results of the CPM method for accelerating project time explain that activity A is preparation for preparing tools and materials. Activity B is making a foam pattern consisting of a seat, back, and armrests. Activity C is making patterns on oscar velvet which consists of seats, backs, and armrests. Activity D is foam cutting which consists of a seat, back, and armrests. Activity E is cutting Oscar's velvet fabric which consists of a seat, backrest, and armrests. Activity F installation of plastic shells for seat, backrest and arms. Activity G installation of seats, backrests, and armrests using hinge gears. Activity H RFID Installation. Activity I trial RFID.

Abstract

Study portable desks can help people easily move from one another place. Using a study portable desk would make users fix the position once a few moments so that they risk experiencing bodily discomfort. Analysis indications of posture risk can be done by selecting launch rapid upper limb assessment (RULA) analysis from the ergonomic tools toolbar in CATIA software. This research aims to identify movements that occur when using a portable study desk and to analyze user posture risks that can be experienced when using a portable study desk. Based on the research results, it is known that the body posture of portable study desk users for group A on the upper arms is in the range of 20-45°, and the lower arms are in the range of 60-100°. The wrist enters the neutral position range. The rotation of the wrist can be seen that the hand is pointing inward. It has a degree of freedom of 90° with a maximum flexion angle of 160° and a minimum extension angle of 0°. Group B body posture for the stem body has a degree of freedom of 0°. The legs experience a slight downward movement with a degree of freedom of 6.061° and a maximum flexion angle of 135°. Posture analysis results for body parts. Details of the upper arm, forearm, wrist, and wrist twist have a score of 1, which means no posture needs to be corrected and the posture is acceptable. Details of body parts, namely neck, trunk, and legs, are indicated in green, which means no posture needs to be corrected and the posture is acceptable. The score results for body parts with the static posture option get an assessment score of 2 with a green color indication, so it can be concluded that the risk indication for this posture is acceptable.
