Abstract

Kuantisasi warna citra merupakan operasi penting pada banyak aplikasi grafik dan pengolahan citra.  Metode kuantisasi warna banyak dilakukan dengan menggunakan algoritma klasterisasi data. Kepopuleran k-means sebagai algoritma klasterisasi data yang telah umum, ternyata belum mendapat cukup perhatian pada literatur kuantisasi warna. Hal ini disebabkan karena mahalnya biaya komputasi dan sensitivitasnya terhadap pengaruh pemilihan pusat klaster. Penelitian ini memberikan metode percepatan algoritma k-means untuk kuantisasi warna. Metode yang diajukan melibatkan beberapa modifikasi pada k-means konvensional, seperti pengurangan data, pembobotan data, dan penggunaan prinsip  pertidaksamaan segitiga untuk mempercepat pencarian ketetanggaan terdekat. Ujicoba dilakukan dengan beragam citra dan menunjukkan bahwa modifikasi yang telah dilakukan mampu memperlihatkan bahwa k-means juga sangat kompetitif sebagai algoritma  kuantisasi warna citra, baik dalam segi efektivitas maupun efisiensinya.

Abstract

Penelitian dilaksanakan di Kebun Percobaan Fakultas Pertanian Universitas Asahan, Kabupaten Asahan, Propinsi Sumatera Utara dengan topografi datar dan tinggi tempat ± 15 m dpl. Penelitian dilaksanakan pada bulan April sampai bulan Mei 2017. Bahan yang digunakan dalam percobaan ini antara lain benih sawi kailan, bokashi eceng gondok, berbagai urin ternak (urin sapi dan urin kambing), insektisida Matador 25 EC, fungisida Dithane M-45, dan air. Alat yang digunakan selama percobaan ini adalah cangkul dan garu yang digunakan untuk mengolah tanah,baby polibag untuk penyemaian benih, patok, tugal, tali rapia, meteran, digunakan dalam pembuatan plot dan penanaman,kep sprayer yang digunakan untuk aplikasi pupuk, penggaris, timbangan, alat tulis, ember dan gembor digunakan untuk penyiraman. Penelitian ini disusun berdasarkan Rancangan Acak Kelompok (RAK) Faktorial dengan 2 faktor perlakuan dan 3 ulangan. Faktor pertama, pemberian bokashi eceng gondok, terdiri dari 4 taraf : G0 = 0 kg/plot, G1 = 1,44 kg/plot, G2 = 2,88 kg/plot dan G3 = 4,32 kg/plot. Faktor kedua pemberian berbagai urin ternak (T), terdiri dari 3 taraf, yaitu T0 = tanpa perlakuan, T1 = urin sapi dan T2 = urin kambing. Hasil penelitian bahwa Pemberian bokashi eceng gondok berpengaruh nyata terhadap tinggi tanaman, jumlah daun, produksi per sampel dan produksi per plot, dengan dosis terbaik pada perlakuan 4,32 kg/plot (G3), menghasilkan produksi 2,84 kg. Pemberian berbagai jenis urin ternak berpengaruh nyata terhadap tinggi tanaman, jumlah daun, produksi per tanaman sampel dan produksi per plot, dengan perlakuan terbaik adalah urin kambing (T2) menghasilkan produksi 2,56 kg. Interaksi antara pemberian bokashi eceng gondok dan berbagai jenis urin ternak terhadap pertumbuhan dan produksi tanaman sawi kailan menunjukan pengaruh yang tidak nyata terhadap seluruh parameter yang diamati.

Abstract

This research reveals as well as examines the relationship between the acceptability of Covid-19 vaccine information on health awareness in the tourism industry sector in the city of Bandung. This city is one of the tourist destinations that must rise from adversity due to Covid-19. The vaccine program was launched by the government to attract tourists again. The approach to answering this research uses a positivistic paradigm with quantitative research techniques. The validity and reliability test using SPSS was carried out on 85 respondents from a population of 300. A strong relationship was found between the acceptability of the Covid 19 vaccine information and the health awareness of tourism sector business actors in the city of Bandung. They were positive to receive information about the Covid vaccine to run their business. This study also found that respondents received vaccine information based on the purpose so that their business could run. It was also revealed that respondents were not sure with certainty that they could carry out the vaccine process. Furthermore, significant data were found that respondents were less active in seeking information about health.

Abstract

Abstracts. This study aims to determine the readiness of 2017 Electrical Engineering Education (PTE) students in facing Industrial Practices (PI). The existence of Higher Education (PT) especially vocational education plays an important role in the nation's development going forward, because the current condition of globalization requires professional and skilled workers who must be able to work in accordance with their competencies. The development of increasingly sophisticated technology requires an increase in the quality of Human Resources (HR) who inevitably adapt to these changes. This research is a qualitative research using a descriptive approach. The population of this research is eight lecturers of PI supervisors and 32 PTE fifth semester students. The evaluation results show that PTE students are ready to do PIs, this is supported by the level of student knowledge, socialization carried out by PTE study programs as well as adequate basic skills of students. In the PTE student activities implementing PI has been going well which is supported by the ability of students to adapt in the industrial environment. PI assessment is done by paying attention to attendance, discipline, motivation, work quality, initiative, creativity, behavior and work skills.

Abstract

 Developmental problems concerned by parents are a further diagnostic step for children with Autism Spectrum Disorder (ASD). Research is needed to find a picture of the child's behavior complained of by parents. Investigations about first concerns among parents of children with ASD and comparisons of the same with children diagnosed with other developmental disorders are rare. We want to examine the type and age of parents ‘concern in children with ASD and other developmental disorders. A cross-sectional study was conducted in Child Developmental Centre in Surabaya Indonesia from August 1 to December 30, 2019. T-test and chi-square tests were used to analyze differences in subject variables and types of concern. Most parents of both children diagnosed with ASD and non-ASD indicated first concern were in communication, social skill, and behavior problem. The average age of parents’ first concern of ASD children is 30,14 months. Significant differences were found between ASD and non-ASD groups in communications, behavior, and sensory problem concerns. There is no specific difference between parental concerns of children with ASD and non-ASD children. The average age of first concern was significantly younger for children with an ASD diagnosis than other developmental disorders.Keywords             :parent concern, autism, communication.Correspondence     :dian_dwisary@yahoo,com

Abstract

This research aims to obtain a concentration of soursop leaf flour extract which is effective to control the larvae of Oryctes rhinoceros L. The research was conducted at the Plant Pest Laboratory, Faculty of Agriculture, Riau University. The research was conducted for two months from April 2019 to May 2019. The research was conducted experimentally using a completely randomized design (CRD) consisting of 5 treatments and 4 replications, so that 20 experimental units were obtained. The treatments given were the concentration of soursop leaf extract 0 g.l-1 water, 25 gl-1 water, 50 gl-1 water, 75 gl-1 water and 100 gl-1 water. The parameters observed were the initial time of death, lethal time, lethal concentration, daily mortality, total mortality, temperature and humidity. The observed parameters data were analyzed by variance and followed by LSD at 5% level. The results showed that giving of soursop leaf powder extract at the higest concentration is 100 g.l-1 water was control O. rhinoceros L. larvae with a total mortality of 60%. This has not been effective in controlling O. rhinoceros L. larvae because it has not been able to cause a total mortality above 80%. The correct concentration caused a total mortality of 50% of O. rhinoceros L. larvae was 8.4% or the equivalent of 84 g.l-1 water extract of soursop leaf flour. The concentration that was able to produce a total mortality of 95% of O. rhinoceros L. larvae was 55.2% or the equivalent of 552 g.l-1 water extract of soursop leaf flour. Keywords:Oryctes rhinoceros, extract of soursop leaf flour, concentration, botanical insecticide
