Content:

Bamboo is an environmentally friendly material. Various types of bamboos thrive in Indonesia. To differentiate good types of bamboos, this study uses the K-Means color segmentation method and shape measurement. Due to bamboo has fibers content and fibers adhesive which reflected the quality of bamboo. Then the research uses the morphological parameters of area and perimeter as a feature of size. The analysis is carried out on 45 bamboo images, namely 15 Wulung bamboo images, 15 Petung bamboo images and 15 Ori bamboo images. Based on the test results obtained, there are as many as 0.6 accurate images. The testing uses 15 types of bamboo imagery. The bamboo which has the largest fiber size is Wulung bamboo and then followed by Petung bamboo and the smallest is Ori bamboo.

P R E F A C E

Good morning,

It is my great pleasure to welcome you to the Sixth International Conference on Mathematics, Science, and Education (ICMSE) 2019 organized by Faculty of Mathematics and Natural Sciences Universitas Negeri Semarang (UNNES). This conference is designed as the annual meeting to share knowledge and product of research. By choosing the theme of “Commercialising Innovative Research in Science, Mathemathics, and Education for Addressing Industrial 4.0 Era”, we hope that this conference will encourage and facilitate the researchers, teachers, and experts in mathematics and science areas to promote their research results. We also invite several keynote speakers from the relevant field of study to share their expertise related to the conference theme.

Additionally, it is encouraging to note that ICMSE 2019 involves participants from various departments and research groups of the faculty who have contributed as the special session chairs.

This cross-department initiation allows members to upgrade and relate their expertise as academicians in the field of mathematics and science. This in turn encourages better research collaboration in mathematics and science and their related field for researchers, teachers, and experts.We expect to have 300 participants from several countries in Asia, Europe, and Australia in this conference.

This conference will not be possible without the support from the FMIPA, International Seminar Grant from Dikti, Journal Editors, and the Rector of UNNES. Thanks to all of you. I wish also to thank all members of the organizing committee for your good work, patience, commitment for succeeding this conference

Abstract. Bamboo is an environmentally friendly material. Various types of bamboos thrive in Indonesia. To differentiate good types of bamboos, this study uses the K-Means color segmentation method and shape measurement. Due to bamboo has fibers content and fibers adhesive which reflected the quality of bamboo. Then the research uses the morphological parameters of area and perimeter as a feature of size. The analysis is carried out on 45 bamboo images, namely 15 Wulung bamboo images, 15 Petung bamboo images and 15 Ori bamboo images. Based on the test results obtained, there are as many as 0.6 accurate images. The testing uses 15 types of bamboo imagery. The bamboo which has the largest fiber size is Wulung bamboo and then followed by Petung bamboo and the smallest is Ori bamboo.

1. Introduction

The identification of objects in digital image processing is by measuring the texture, shape and color of the object[1]. Measurement by image textures only uses spatial data has flaws so we need to measure objects based on the size of their shapes. Bamboo fiber is a natural fiber which is an environmentally friendly material, we can take many benefits from the bamboo fiber. Bamboo has a constituent namely fiber and fiber adhesive. Based on laboratory testing, the wider diameter of bamboo fiber is the better quality of the fiber[2]. Many types of bamboo thrive in Indonesia, so we need a method that allows us to identify and distinguish the characteristics of each type of bamboo. Characteristics are different characteristics in each image quality such as pixel intensity, edges, contours, regions and so on [3]. To determine the characteristics of the image, the image can be distinguished using the visual characteristics of the image in the form of color, shape and texture [4].

This study intends to measure the amount of bamboo fiber by knowing the characteristics of each bamboo. The method used in segmentation is color image segmentation with K-Means and measuring the amount of bamboo fiber with its visual parameters namely color texture and measuring the area of an object [5]. Bamboo image representation uses an internal region representation that is the ratio of pixels in a region. To measure the area of an object, the commonly used parameter is by calculating the area of an object segmented as well as calculating the length of the perimeter of an object segmented to identify a particular object[6].

(57)

2. Method

The method used to identify objects in this study is based on color image segmetation and shape features by measuring the area of the object (bamboo fiber) from segmentation results.

This study uses 3 types of bamboo images that are often used for industry in Semarang, including Ori bamboo, Petung bamboo and Wulung bamboo. The method of this image processing is shown in figure 1 below :

Figure 1. Step of Image Processing

2.1. Data Acquisition

Data acquisition is the process of getting data in the form of bamboo images. The tool used is the Canon D 60 camera. The process of shooting bamboo is done in the morning at 10-11 am where the sun is in bright conditions there is no cloud and no significant wind.

2.2. Pre Processing

Before processing the image, the image obtained from the capturing results in the crop into the same size is 400 x 400 pixel resolutions. After the image is of the same size then the image segmentation is then performed using k-means color segmentation.

2.3. Segmentation

This study use a color based segmentation. This study begins with the converting of original image color space RGB (Red Green Blue) color to HSV color. This study uses the HSV color space standard.

The purpose of forming a color space is to facilitate color specifications in the form of a standard.

Because HSV is a color space that is more representative of color as seen by the human eye, [7] this study converts the RGB color space into the HSV color space. H comes from the word "hue", S comes from the word "saturation", and V comes from the word "value". Hue is a color known to humans like red and green. Hue reflects the color that is captured by the human eye in response to the wavelength of light. Saturation expresses the degree of purity of color or how much white light is mixed with hue. Each pure color is 100% saturated and does not contain white light at all so pure colors mixed with white light have saturations between 0 and 100%. Value or sometimes called brightness states the intensity of the

(58)

Figure 2. HSV color space

The HSV model was first introduced by A. R. Smith in 1978. To get the H, S, V values, the calculation is based on the values of R, G, and B.

• 𝐻 = tan⁡((𝑅−𝐺)+(𝑅−𝐵)^{3(𝐺−𝐵)} )

• 𝑆 = 1 −min⁡(𝑅,𝐺,𝐵) 𝑉

• 𝑉 =^{𝑅+𝐺+𝐵}

3

However, this method makes hue undefined if S is zero. The second method is found in Acharya & Ray [8]. The formulas used are as follows:

▪ 𝑟 = ^𝑅

(𝑅+𝐺+𝐵)⁡, 𝑔 = ^𝐺

(𝑅+𝐺+𝐵) , 𝑏 = ^𝐵

(𝑅+𝐺+𝐵)

▪ 𝑉 = max⁡(𝑟, 𝑔, 𝑏)

▪ 𝑆 = {0,⁡⁡⁡⁡⁡⁡⁡⁡⁡⁡⁡⁡⁡⁡⁡⁡jika⁡V = 0 1 −^{min(𝑟,𝑔,𝑏)}

𝑉 , V > 0

▪ 𝐻 =

{

0, 𝑗𝑖𝑘𝑎⁡𝑆 = 0

60∗(𝑔−𝑏)

𝑆∗𝑉 , 𝑗𝑖𝑘𝑎⁡𝑉 = 𝑟 60 ∗ [2 +^𝑏−𝑟

𝑆∗𝑉] , 𝑗𝑖𝑘𝑎⁡𝑉 = 𝑔 60 ∗ [4 +^𝑟−𝑔_𝑆∗𝑉] , 𝑗𝑖𝑘𝑎⁡𝑉 = 𝑏

• 𝐻 = H + 360⁡jika⁡H < 0

2.4. Morphological And Shape Feature Extraction

Morphological parameters that are used to distinguish the phases of development of bamboo in this study are the area ratio and perimeter. Shape feature is a feature obtained through shape object and can be expressed trough area , countour and transformation. This study use morphological features which can be extracted from an object in the image are the area ratio and perimeter. Area ratio is the ratio between number of pixels that make up an object and the image size. Measuring the area of the object segmented using the area and perimeter. The size feature extracted using region prop [9] . The perimeter gives good results when the edges of objects are connected with 4-neighbors, but it is not appropriate when connected according to 8-neighbors [10]. That happens because the distance between two pixels is not constant, whereas the distance is always 1 at 4-neighbors.

If the edge of an object is processed using the perimeter, it can be estimated using the formula:

𝑃 = 𝑁_𝑒+ 𝑁_𝑜√2

with Ne stating the number of even codes and No stating the number of odd codes..

Meanwhile, to calculate the area of an object, a simple way is by counting the number of pixels on the object[11].
