Abstract

Abstrak Karat dan mosaik adalah penyakit pada tebu yang menyerang tebu di Indonesia dan menimbulkan kerugian. Teknologi informasi untuk deteksi penyakit tebu diperlukan dalam menunjang peningkatan produksi tebu yang dapat menghasilkan panen optimal. Penelitian yang berkembang dalam identifikasi penyakit tanaman melalui identifikasi citra digital daun belum ada yang khusus membahas tebu, tetapi mengenai penyakit tanaman secara umum. Penelitian ini membangun sistem identifikasi penyakit pada daun tebu melalui identifikasi citra digital daun dengan pemilihan fitur tekstur dan warna melalui gray level co-occurrence matrix (GLCM) dan color moments. Tahap awal penelitian adalah pengumpulan data citra daun tebu berpenyakit dari survei lapangan. Tahap selanjutnya adalah pre-processing citra untuk dapat diolah ke tahap selanjutnya yaitu ekstraksi fitur. Ekstraksi fitur tekstur dilakukan dengan gray level co-occurrence matrix (GLCM) dan ekstraksi fitur warna dengan color moments. Klasifikasi dilakukan berdasarkan fitur yang telah diekstraksi sebelumnya. Penelitian ini menggunakan metode klasifikasi support vector machine (SVM). Pengujian dilakukan untuk mengetahui fitur yang kemunculannya menyebabkan perubahan dalam hasil klasifikasi dengan 4 skenario meliputi penghapusan fitur bentuk, pemilihan fitur tekstur, pemilihan fitur warna, dan kombinasi fitur tekstur dan warna. Kombinasi fitur tekstur dengan GLCM correlation, energy,  homogeneity dan variance bersama fitur warna dengan color moments 1,2 dan 3 yang diuji pada skenario 4 merupakan kombinasi fitur yang direkomendasikan untuk identifikasi penyakit pada daun tebu dengan akurasi 97%. Kata kunci: ekstraksi fitur, penyakit tebu, citra daun, GLCM, dan color moments. Abstract Mosaic and rust are sugarcane diseases that happen in Indonesia and has considerable economic impact. Information technology for sugarcane disease detection is useful in supporting optimal sugarcane production. Most of current researches are about plant disease identification in general. There is no specific research about identification of sugarcane disease. This research proposes a sugarcane disease identification from sugarcane leaf image with gray level co-occurrence matrix (GLCM) and color moments. This research begins with collecting data from field survey. After sugarcane leaf images are captured through a field survey, they are pre-processed in order to be used in the features extraction step. Extracted features from these images are texture and color. Texture feature extraction is conducted by GLCM while color feature extraction is conducted by color moments. Classification method which is used in this research is support vector machine (SVM). Test conducted to find distinctive feature that has a significant impact in classification, there are 4 scenario to test the effects in deletion of shape feature, selection of texture and color feature, and also combination of texture and color feature. Texture feature with GLCM correlation, energy,  homogeneity and variance combined with color moments 1, 2 and 3 for color feature extraction in 4th scenario is an appropriate feature for identification of sugarcane leaf disease with 97% classification accuracy. Keywords: feature extraction, sugarcane disease, leaf image, GLCM and color moments.

Abstract

Job fair merupakan kegiatan yang mempertemukan pencari lowongan kerja dengan perusahaan penyedia lowongan kerja pada suatu tempat dan bertujuan untuk mengurangi angka pengangguran pada suatu wilayah. Job fair yang semula diadakan secara luring kini ditiadakan untuk mengurangi dampak penyebaran virus Covid-19. Akibatnya, angka pengangguran di Indonesia menjadi 8,75 juta pada bulan Februari 2021, dimana angka tersebut meningkat 26,26% dari angka pengangguran pada bulan Februari 2020. Untuk menindaklanjuti permasalahan tersebut, Laboratorium Teknologi Media, Game dan Mobile, Fakultas Ilmu Komputer, Universitas Brawijaya berkolaborasi dengan PT. Indogetjob International Solution menciptakan solusi dengan membangun aplikasi mobile portal job fair Sarjana Sakti. Aplikasi tersebut dilengkapi dengan asesmen soft skills sebagaimana HRD perusahaan melakukan proses rekrutmen. Aplikasi ini dirancang dengan menggunakan pendekatan Human-Centered Design (HCD) karena memiliki strategi desain yang iterative untuk mendapatkan hasil yang diharapkan. Pada tahap evaluasi desain solusi dilakukan dengan melakukan pengujian usability dan user experience kepada 10 partisipan. Hasil pengujian usability pada aspek effectiveness 97,8125%, aspek efficiency 0,079 goals/second dan pada aspek satisfaction 88,25 yang masuk dalam grade A+, kategori acceptable dan termasuk adjective best imaginable. Hasil pengujian User Experience Questionnaire (UEQ) pada skala attractiveness 2.63, skala perspicuity 2.60, skala efficiency 2.75, skala dependability 2.43, skala stimulation 2.68 dan skala novelty 2.45. AbstractJob fair is an activity that brings job seekers with companies that provide job vacancies in one place together and aims to reduce unemployment in certain areas. Job fair, which is an offline event, has been canceled to reduce the spread of COVID-19 virus. Therefore, the unemployment rate in Indonesia will reach 8.75 million in February 2021, which is an increase of 26.26% from the unemployment rate in February 2020. To overcome this problem, Media, Game and Mobile Technology (MGM) Laboratory, Faculty of Computer Science, Brawijaya University collaborates with PT. Indogetjob International Solution to develop a job fair portal mobile application called Sarjana Sakti. This application is equipped with a soft skill assessment as the company’s HRD recruits. The Human-Centered Design approach method is used in designing this application. This application was designed using the Human-Centered Design approach because it has an iterative design strategy to get the expected results. At the solution design evaluation stage, usability and user experience tests were carried out on 10 participants. The result of usability testing on the aspect of effectiveness is 97.8125%, efficiency aspect is 0.079 goals/second, and on the satisfaction aspect is 88.25 which is included in A+ grade, acceptable category and includes the best imaginable adjective. The results of user experience testing with UEQ on an attractiveness scale of 2.63, a perspicuity scale of 2.60, an efficiency scale of 2.75, a dependability scale of 2.43, a stimulation scale of 2.68, and a novelty scale of 2.45.

Abstract

Malang is one of the tourist destinations in East Java, and always visited by both domestic and foreign tourists. However, Malang isn’t the first destination in tourism, this is due to the lack of intense promotion. Virtual tourism is a virtual reality technology for promoting tourism. Based on these problems, the researchers developed a virtual reality application that can provide immersive experiences to users assembled with tourist destinations in Malang. Application was developed using React 360 framework, because of its ease of development and can be developed for various platforms. The Software Development Life Cycle (SDLC) is the waterfall method. The implementation using VR Headset and VR Controller. In testing, researchers conducted functional testing and non-functional testing. Functional testing is done using black box testing and non-functional testing is done by the System Usability Scale (SUS) method. The results of functional testing using black box are 100% valid. In the usability test, the System Usability Scale (SUS) questionaire obtained a score of 89. From the scores that have been obtained, this application is acceptable, with Grade A and adjective rating Excellent.
