Klasifikasi Kualitas Biji Kopi Menggunakan MultilayerPerceptron Berbasis Fitur Warna LCH

Coffee is one of Indonesia's foreign exchange earners and plays an important role in the development of the plantation industry. In previous studies, coffee bean quality research has been carried out using the ANN method using color features. RGB and GLCM. However, the results carried out in the study only had an accuracy value of up to 47%. Therefore, this study aims to improve the performance of coffee bean quality classification using four machine learning methods and 7 color features. From the results obtained, it shows that MultilayerPerceptron is better starting with RGB color with an accuracy of 38% split ratio 90:10. HSV has an accuracy of 57% split ratio 90:10. CMYK has an accuracy of 63% split ratio 90:10. LAB has a 58% curation split ratio of 90:10. The YUV type has an accuracy of 58% split ratio 90:10. Furthermore, the HSI color type has an accuracy of 42% split ratio 90:10. The HCL color type has an accuracy of 65% split ratio 90:10 and LCH has an accuracy of 78% split ratio 90:10. In testing, it can be concluded that the MultilayerPerceptron method is better than other methods for the coffee bean classification process.

CHARACTERISTICS OF THE POLYMORPHISM OF THE GREEN TOAD BUFO VIRIDIS (LAURENTI, 1768) IN THE BIOCENOSES OF THE SOUTHERN URALS (REPUBLIC OF BASHKORTOSTAN)

The results of the study of the features of polymorphism of green toad populations in the conditions of the Trans-Urals of the Republic of Bashkortostan are presented. It was found that among the green toads in the urbanized territories of the Trans-Urals, individuals with the color type M3 ("light background, merged spots") and M4 ("dark background, merged spots") prevail. There was a decrease in the diversity index in the conditions of low-rise buildings (m=1.995), as well as industrial (m=2.843) and green zones (m=2.986) relative to the control areas (3.286<m<3.99).

Study of properties of male mink skins obtained from animals with different degrees of invasion intensity

The results of the study on indicators of some commercial properties and the assessment of the quality of farm male mink skins obtained from the animals with a various degree of intensity of eimeriosis invasion are given in the article. Eimeriosis invasion of male mink population is a vital reason for cessation of the growth of young mink and also their increased mortality and change in the quality of their hair-covering for the worse. The skins of male farm mink of the standard dark brown (SDB) color type with a various degree of invasion intensity were taken as materials for the investigations from the fur farm in Kaliningrad Region of the Northwestern District of the Russian Federation and were divided into four experimental groups. The first group of skins was obtained from clinically healthy animals, the second group of skins – from the sick ones with a weak degree of invasion intensity, the third group of skins – from the sick mink diseased with eimeriosis of a medium degree of invasion intensity, the fourth group of skins – from the mink with eimeriosis of a high degree of invasion intensity. The analysis of the results of the study on the indicators of natural and true hair length and thickness and height of the hair-covering, size of male mink skins with a various degree of invasion is presented in the article.

Structural features of the chinchilla pelts haircovering of different color types

In order to form national chinchilla breeding market sector it is necessary to determine the main parameters that can characterize chinchilla furs of local production, classify them as fur and peltry and establish standard indicators for this kind of commercial production. Chinchilla peltry with its softness, tenderness, velvety texture and high aesthetic properties are in great demand by consumers. The article provides information on the structure of chinchilla hair-covering, characteristics of hair types, hair form, degree of tortuosity. The results of the study of the length and thickness of the down hair according to the color type of chinchilla pelts and topographical part (spine, rump or side) are given in the article. The author gives recommendations on chinchilla selection in order to improve the pelt quality.

Fasilitas Penyegaran Mental

Millennials are facing many challenges in this era. Of course, the growth spurt of technology and business brings positive changes but also negatives for physical and mental. One of the negative sides is the higher rate of stress that causes people to demand a refreshment facility, where the word ‘refreshment’ itself means to give energy physicallly and mentally. Seeing from the programs needed and the project location, produce a building design that adapt tropical style and post-modern architecture without leaving the traditional value. With highly slanted roof and having many skylights protruding the tropical style of the building. The façade uses basic materials like woods, concrete, and glass with warm tone color. Type and behavior also take important roles by co-influencing each other. Type itself is a concept that occurs in typology which determines whether the new typology will be the same as it is before or will it be a new form of typology that start a breakthrough. Instead, this project must use pattern language method of design which makes complicated design more simplified, and in the end produces a final design that answers the Milenial problems. AbstrakGenerasi milenial menghadapi banyak tantangan zaman. Tentu saja kemajuan teknologi dan bisnis dengan pesat membawa dampak positif namun juga dampak negatif bagi fisik dan mental. Dampak negatif mental yang terjadi adalah kecenderungan stress yang tinggi sehingga diperlukan sebuah fasilitas penyegaran, dimana arti kata ‘penyegaran’ sendiri adalah memberikan energi bagi fisik dan mental. Sehingga melihat dari kebutuhan program dan lokasi proyek, menghasilkan sebuah bangunan yang bergaya tropis dan berasitektur post-modern namun tidak meninggalkan cirikhas tradisional. Dengan atap yang juga berkemiringan curam dan memiliki banyak skylight menonjolkan cirikhas tropis dari bangunan. Fasad bangunan juga banyak mengandalkan material-material dasar kayu, beton dan kaca dengan warna-warna bernuansa hangat. Tipe dan perilaku juga berperan penting dengan cara saling mempengaruhi. Tipe sendiri merupakan sebuah konsep yang kemudian ada pada tipologi yaitu apakah tipologi bangunan yang akan terbentuk akan sama dengan sebelum-sebelumnya atau malah akan terbentuk tipologi baru yang akan membuat sebuah terobosan. Selain itu, proyek ini juga harus menggunakan metode penelitian pattern language yang dapat mempermudah proses desain yang rumit sehingga menghasilkan program ruang yang beragam.
