Augmented Reality (AR) and Virtual Reality (VR) which are one of the top ten strategic technology trends for 2019 and continue to be developed massively in this 2020, have been widely applied in various mobile applications by many companies in this industrial revolution era 4.0. AR can be applied to help the promotion for housing developers where users can see the 3-dimensional shape of the types of houses offered, while VR allows users to explore each part of the house in a virtual 3D. Pre-existing brochures are used as markers for this application to work, so that AR and VR applications can be a complement to promotional media. The design method used in this paper is Research and Development (RnD). Salespeople can offer types of houses to prospective customers without having to print multiple brochures, but with just one brochure and one android smartphone to present, so the promotion costs are more efficient.   Keywords: AR, VR, house.

The transformation of objects in computer graphics is very closely related to the factor of scale and rotation. Both are often a challenge in the introduction of objects through numerical features in digital images. Feature processing techniques that can overcome these problems such as Distance - Angle signature that is invariant to the scale and rotation factor. From the results of experiments conducted on 5 types of geometric shape images which amounted to 15 data with scale and rotation factors obtained the results that the Angle Signature can be applied well on all data. Inequality in the signature plot images obtained is due to the lighting conditions and background objects that are not uniform, which occurs in the image of a circle for all three types.

Kaliwungu Dream Building Shop is a business engaged in the sale of building materials and building-producing tools. This trading business sells various materials and tools for building buildings such as sand, cement, nails, paint, hammers and so on.

In addition, the process of searching for data or inventory is also less effective and efficient. also affect customers, even though performance according to the store is needed to satisfy customers.

Camisole is one of the underwear that is commonly used to improve body shape so that it looks more beautiful and proportional. Most of the camisole is made by using a baleine stitch and attachd to the main material, this time the writer wants to try new things in making a camisole. Such as selection and placement Baleine on a camisole as a complement to a party outfit. The objectives of this research are: 1) To know the right type of baleine on a camisole; 2) Can know the placement of baleine on a camisole. The methods used in the selection and placement of baleine on a camisole as a complement to the party dress are: 1) R&D method; 2) Data Analysis. The selection and placement of Baleine on the camisole as a complement to the party outfit begins with determining the design. Camisole design to be made, preparation of tools and materials, taking measurements, making basic patterns, breaking patterns, cutting steps, and determining baleinejahit and baleine stitches that will be installed on the main material or will be attached to the furing (sewing process). Baleine installation can be done in two ways, namely attaching it to the main material and attaching it to the lining. It turns out that baleine sewing is more effective for making camisole, the result of a camisole that uses baleine sewing looks firm and good when used.

One type of clothing is ready to wear, in the form of ready-to-wear clothing. Currently this clothing is a trend, with monochrome colors and geometric motifs. The goal to be achieved is to make Monochromatic Tri-Angle ready-to-wear clothes. The data collection methodology used was in the form of observation, documentation, and literature. The fabric motif in the form of geometric shapes can be found on the Jepara Troso woven fabric. This outfit is based on a monochrome source of ideas, a triangle shape, and a Bird of Paradise. This dress is a party dress for non-formal parties. Consists of three parts, namely a long sleeved blouse with a balloon style with hidden buttons and no collar, a sleeveless outer length, then a custom skirt with a slit and a span skirt inside. Making ready to wear Monochromatic Tri-Angle party dresses includes several processes. The first is to make a design, then from the design it is developed into a pattern with a predetermined formula and size. After that cutting the material, laying the pattern on the fabric should be as much as possible so as not to waste a lot of material. Then the sewing process, which is combining the pieces of material. The last one is the solution, which includes attaching the rubbing stone application using a special tool, cleaning clothes from threads and ironing clothes to make them tidier.
