Background
This study is based on the author's interest in wood material related to its use for the floor in the workspace because space is forming an office element. Focus attention on whether there are problems that arise when implementing in shaping space in an office. As we all know, the office is the main support tool for someone to do their job. For that, there is a need for a clean and tidy office interior design. The office atmosphere can be more focused and concentrated because the office workspace is a room where space users will spend much time carrying out their activities.
The workspace is one of the spaces to find inspiration to organize our future. Therefore, we must ensure that our workspace can support these activities properly. An important factor in creating a workspace is using wood as the work floor for our convenience work. The bed in a workspace is an important component in an office interior. Choosing wood flooring will make a perfect and elegant difference compared to other flooring materials. Using wood flooring will also get comfort and natural effects and have an expensive artistic value. Creating a comfortable atmosphere in the office's workspace, of course, will make us more relaxed and excited in carrying out our daily work. Different design touches in the workspace will create a fresh and new feel when we work. Natural elements from wooden floors make the workspace's interior design not boring, feels warm, and does not cause pressure at work.
In this study, we focus our attention on the use of flooring materials at PT Pupuk Indonesia as a model considering the space users' comfort and safety. Models are necessary because every creativity requires a model (Sunarto 2015, 289-90;2020, 108-10). The material in question is warm, soft, with an attractive texture, and has extraordinary durability, and the material is wood or solid parquet. Therefore, it is very important to research parquet wood flooring in this study because wood flooring in the workspace can help solve the ergonomic problem of materials from aesthetics, comfort, and safety. This article has three kinds of contributions to the development of Interior Design knowledge. The first is to provide direction in applying theoretical and practical studies in the field of interior design. The next contribution is to provide material for consideration for teachers in interior design to improve design disciplines. Third, contribute ideas to improve learning outcomes and improve education quality, especially for the Interior Design Study Program students.

Problem Identification
The problem is the wooden floor material applied in the workspace, which is an obstacle for users who wish to increase the comfort, safety, and aesthetics of space's interior; however, given the floor material's nature, that impacts making noise in its use. Then, the problem arises regarding what types of wood are suitable for use as workspace floors? Moreover, what obstacles will appear in designing the interior design related to using the wood material's comfort and safety? Given the limited time, some of the existing problems are determined only on the issues discussed in this study. The problem is limited to the wood used on the workspace floor in the office. Based on the explanation above, the writer determines the research problem to studying workspace wood flooring at PT Pupuk Indonesian in this study.

Research Urgency
The urgency of research is to find new knowledge, develop knowledge and test the truth of experience. The methodology is a path that researchers must take to obtain broad and relevant knowledge (Hadi 2001, 10). This research's urgency is important considering the research on the ergonomics of wood for office workspace floors needs to get serious attention because of its use related to aesthetics, comfort, and safety for space users in carrying out daily activities workspace. In this applied research, the author tries to solve the problems faced in the use of wood flooring in the office space of PT Pupuk Indonesia, Jakarta. This research study's approach is descriptive qualitative, which describes the ergonomic condition of the wood on the floor of an office workspace through observation and documentation, in describing the research object, observing the problems that occur, then finding out the things that cause problems in the ergonomics of the wood flooring material.
After obtaining the theories as to the basis for the research, further observations were made to find out factual data on the state of the workspace floor material, then classified the data to make it easier to identify existing problems. Furthermore, the field data obtained is then analyzed by adhering to the relevant literature related to the application of floor materials to the interior of the workspace, in general, to conclude the factors that cause the problem. In this study, the output has high urgency because it has implications for interior design education from ergonomic wood flooring research. The speed and consequences of this will appear in the conclusions presented.

Understanding of the Floor
The floor is one of the most important elements in an interior. The base is the lower limit for the interior of a room. The floor stretches out horizontally. Applying various materials to the bed varies, using different floor heights and applying the form's essence. Various building materials appear in designing a space. We need special attention in determining the building material for the floor, especially in terms of space function, user character type, atmosphere creation, safety, and maintenance.
Wood is a forest product from natural resources. In this advanced technological situation, wood is a raw material whose processing to become goods is very easy (Dumanauw 1990, 1). The shape of wood has warm, soft properties and a very attractive and unique surface. Most of the solid wood floors are on the subfloor, consisting of chipboard, plywood, or hardboard (John McGowan, John & Dubern 1991, 100). Ching Francis revealed that floors are the flat, level base planes of interior space. The floor is a flat surface and is the basic surface of the inner room, is the base as the physical support, and is the visual base for the building's shape. Since the floor area supports our building activities, the  The table above shows that wood/parquet has advantages over other floor materials from aesthetic elements; it is comfortable and safe to use. Besides, wooden / parquet floors are easy to maintain and economically affordable.

Aesthetic Elements, Comfort and Security
Interior design must contain aesthetic elements that refer to design principles such as proportion, space scale, balance, space harmony, unity and variety of space, space rhythm, space emphasis, and things such as beauty space accessories. Aesthetics is a combination of science and philosophy. The origin of the word aesthetics is from the Greek aisthetikos or aishtanomai, which means to perceive with the senses (Kellerman 1977, 18). This understanding is also related to the Greek term aesthetic, which means observation. Feldman sees aesthetics as a science of observation or science of senses, referring to sense impressions. Likewise with J. Addison, combining aesthetics with taste theory. Aesthetics, as a science, rests on observation activities using the five senses, namely (1) eyes as a sense of sight, (2) the nose as a sense of smell, (3) the ear as a sense of hearing, (4) the tongue as a sense of taste, and (5) skin as a sense of touch (Dickie 1989, 219).
The beauty requirement is to create an attractive space atmosphere by processing floor materials and colors that consider function and aesthetic factors because floors are also an important design element in space. Its shape, color, pattern, and texture will determine how far it creates an impression in area, defines space boundaries, and acts as a visual base for other elements in the visible space.

Ergonomic Requirements for Public Space Floors
Interior design is planning, arranging, and designing the room in a building, which meets the needs for shelter and shelter, determines and organizes activities, nurtures aspirations, and expresses ideas, actions, appearance, feelings, and personality (Ching Francis 2010, 46).
Based on the standardization rules applied by the American National Standards relating to general requirements for accessible interiors (General Requirements for Accessible Interior), the general criteria for flooring for high-intensity public places include prerequisites: health and safety/health and safety, construction/construction, physical strength, and appearance/appearance (Reznikoff 1989, 206). Health and safety criteria include the following criteria: flammability, ability to reduce light reflectance, slipperiness, and surface flatness (Sri Ambarwati 2007, 21).
Regarding construction engineering requirements, laying the floor is above the underlayment or cement leveling place. The floor installation is on a leveled cement surface. In other words, the floor construction's basic character is a mixture of cement and sand, which is a reinforcing layer for the building. The floor material application is strong in withstanding many activities (Ching Francis 2010, 163). Beauty requirements serve to create an attractive space atmosphere by processing floor materials and colors that consider function and aesthetic factors because floors are also an important design element in space. The shape, color, pattern, and texture will determine how far it creates an impression in the room, defines space boundaries, and acts as a visual base for other elements in the visible space.

Results and Discussion
From the observations made by the author, factual field data were collected, which would be the basis for analyzing existing problems. The research scope is the leadership's office, consisting of the main director's room, the secretary's room, the large meeting room, the discussion room, the waiting room, and the lobby/receptionist. The following is the plan for the layout of the PT. Pupuk Indonesia is made according to needs and to function and have an attractive appearance, as follows: From the survey results in the field and working drawings, the authors can find physical data on the floor of the PT Pupuk Indonesia in the following  The observations show that the total working floor area of PT Pupuk Indonesia area is 720 M2. In the table above, the site that uses wood/parquet and other ceramics are 710.93 M2. The use of wood/parquet flooring for workspace reaches 420,302 M2 or 60% of the total floor area, and the use of other ceramic floors for work and circulation areas is 290.93 or 40%. The following is an analysis of floor materials based on indicators of aesthetics, comfort, and safety as required by ergonomic considerations in the application of materials, as follows:

Wood Floor Materials on Aesthetic Elements
A floor gave the surface of parquet sheets or wood will provide a rich, warm sheen (Richards 1997, 52). Some of the materials used for floor finishing will affect the formation of space's atmosphere, including floor covering materials that give a warm atmosphere, such as carpets, parquet, wood paths, and wood fibers (Suptandar 1991, 29).
In considering the aesthetics associated with floor materials, four things need attention. First, the application of wooden floor patterns and floor color patterns is for the workspace of the main director, directors, large meeting rooms, small meeting rooms, dining rooms, and discussion rooms covering an area of 420 M2. Second, the analysis of aesthetic elements needs to measure the pattern composition and floor color's processing. Third, the floor pattern uses a straight diagonal double brick pattern, with a regular nad, with a wood color pattern. Fourth, the wood accent can provide the perfect appearance or visualization. However, the motifs, colors, and wood accents still feel very dominant even though they are only decorative elements.
The wood color's dominance can provide a firm and formal emphasis to be suitable for office nuances. Wooden floors in the workspace can balance the room temperature and feel more comfortable on the feet' soles because the wood has fine fibers and patterns. Besides being able to create warmth in the room, wooden floors can add to an activity's aesthetic value in the office.

Wood Floor Materials on the Element of Comfort
Wood as a floor has properties that support comfort, namely warmth to the feet (Fischer-Uhlig, Horst & Jeni 1996, 28). A good work environment will make workers feel comfortable. If workers or employees feel comfortable at work, productivity will certainly increase. Increased productivity will indirectly increase company profits. Many factors affect work comfort. One way is to create it through planning a good physical office environment (Maryati 2008, 148). To understand the relationship between wood flooring and the element of comfort, we must consider several things. Performing analysis to measure the comfort element quantitatively is difficult because it involves many factors. Analyzing comfort is by looking at several things, especially from applying materials that can directly interact with sunlight entering the room. Sunlight comes in because of the window openings on each side of the building. This condition has met the criteria because there is integration with wood and textured parquet floors. This integration is necessary to not cause glare in the middle of the room, which can interfere with a comfortable view. Wooden parquet floors can absorb heat and reduce sound and bring a sense of comfort when on it (wood floor); feet will feel much more comfortable, especially when the room's cold temperature is functioning.

Wood Floor Materials and Security Elements
Floors are the flat, level base planes of interior space (Ching Francis 2010, 162). The floor is a flat surface and is the basic surface of the inner space, is the base as the physical support, and is the visual base for the building's shape. Since the floor area supports our activities in the building, the floor must be appropriate and hold constructively, as in the detailed image below: ISSN 1412-4181, eISSN 2685287X Vol. 16., No. 1, April 2021 Tunjung Atmadi & Ika Yuni Purnama (Application of Wooden Floors in the Interior of the Workspace Office) Constructive requirements in applying floor materials in the office also follow the rules and according to the specified requirements starting from the following stages: 1. Cleaning the work floor / screeding to ensure that the parquet floor is not damp and porous in the future, 2. Installation of solid wood beam bearings to connect the work floor 3. Installation of 15 mm plywood covered with wooden frames in several parts 4. Installing an underlayer between the ground floor and the wooden parquet floor keeps moisture from the bottom rising to the wooden parquet's top. Installation of teak parquet with a certain pattern 5. Each side of the wall is clamped with a hairline finish, glued together with the same material as the parquet floor/stair nosing.

Conclusion
Based on the results of the analysis of observational data and literature data, we can conclude as follows: 1. The right interior planning in an office can create a good working atmosphere. An elegant and characteristic office interior design makes employees feel at home and makes a good impression on visiting guests or clients. One thing that should receive attention in the office interior arrangement is the floor as an element that forms space. The bed can create a workspace that reflects the owner's identity and the company but has ideal properties according to their needs.
2. Types of flooring material selection at PT Pupuk Indonesia are homogeneous teak, marble, granite, and ceramic/tile parquet, finishing according to strength, durability, and ease of maintenance. The application of teak parquet on the side is also under its designation as a workspace area. Besides, the use of wooden parquet floors is for aesthetic reasons or the room's beauty, and the workspace will look more natural with natural wood patterns.
3. The floor is the lowest part of the room. It functions to shape the character and support the activities in the room. As a character builder, floors also have different psychological effects, depending on the material's use. The wooden floor will shape and create a warmer atmosphere. The room is cool as a result of the wood's heat-saving nature. Thus, wooden parquet floors are more comfortable and softer than tiled floors and floors made of marble or granite.
