It can be concluded that FBIM and 5E model are effective to enhance students attitudes toward science

Modifikasi ACO Untuk Penentuan Rute Terpendek Ke Kabupaten/Kota Di Jawa

This research focused on modification ACO algorithm. The purpose of this research was to obtain better performance by modifying the algorithm of Ant Colony Optimization (ACO), particularly in terms of computational speed while maintaining the quality of the solution. Modifications made in this research is the calculation of the probability of the next city to be visit, the ant trail intensity calculations, and modification number of ants to follow the size of the problem. From the results of this research it can be concluded that by modifying the probability of the next city to be visit and the intensity of the ant trail can maintain the quality of the resulting solution with a percentage of 99.8% while the number of ants that used 35% of the size of the problem. In terms of memory USAge, modification ACO algorithm is more efficient than the original ACO algorithm with an average of 7%. In addition, the time required to generate the shortest path on average three times faster than the original ACO.Keywords – ACO, ACO Modified, Shortest Pat

EFEKTIVITAS MULTIMEDIA INTERAKTIF BERBASIS FLASH DAN MODEL 5E UNTUK MENINGKATKAN SIKAP TERHADAP SAINS SISWA SMP NEGERI 6 MATARAM

Abstrak: Penelitian ini bertujuan untuk mengetahui efektivitas dan pengaruh multimedia interaktif berbasis flash (MIBF) dan model 5E terhadap  keterampilan berpikir kritis siswa. Desain penelitian eksperimen adalah pretest-postest non-equivalent control group dan setting pelaksanaan penelitian dengan rancangan faktorial  2 x 2. Populasi penelitian adalah kelas VIII SMPN6 Mataram, sebanyak 196 siswa yang tersebar di 7 kelas. Sampel  dipilih dengan simple random sampling dan diperoleh 97 siswa yang tersebar di 4 kelas yakni kelas VIIIB menerapkan model pembelajaran 5E tanpa menggunakan MIBF, kelas VIIIC menerapkan model pembelajaran 5E dan menggunakan MIBF, Kelas VIIID menerapkan model pembelajaran 2EK tanpa MIBF, dan kelas VIIIE menerapkan model 2EK dan menggunakan MIBF. Hasil penelitian menunjukkan pengaruh penggunaan MIBF (F = 100,96, p = 0,00) dan model 5E (F = 65,46, p = 0,00) pada sikap terhadap sains. Terdapat pengaruh interaksi antara MIBF dan model 5E (F = 38,64, p = 0,00) terhadap keterampilan perpikir kritis dan terdapat pengaruh interaksi antara MIBF dan model  5E(F = 13,05, p = 0,00) pada sikap terhadap sains siswa. Maka dapat disimpulkan bahwa MIBF dan model 5E efektif meningkatkan sikap tergadap sains.Kata kunci: MIBF, model 5E, sikap terhadap sains. Abstract: The aim of this study was to know effectiveness and effect of flash based interactive multimedia (FBIM) and 5E model toward students attitudes toward science.

Validitas Perangkat Pembelajaran IPA Berbasis Masalah Bermuatan Karakter

The purpose of of this study is to determine the validity of a learning tools of characters-based problem on light and optical concept. This type of research is Research & Development refers to Dick & Carey model which consists of ten stages namely: identify instructional goal, conduct instructional analysis, analyze learner and contexts, write performance objektives, develop assessment, develop intrucsional strategy, develop and select instructional material, design and conduct formative evaluation of instruction, revise instruction, design and conduct summative evaluation. The formative evaluation stage was done by: the validation of the learning tools (syllabus, lesson plan, students worksheets, evaluation instruments) by three experts twice validation. Validation has been carried out by experts using a validity test instrument in the form of a questionnaire. Validity test for syllabus, lesson plan, student worksheet and evaluation instruments get results with very feasible. In conclusion, learning tools of characters-based problem on light and optical concept was feasible to be applied in science learning processes

Mental Toughness Dan Competitive Anxiety Pada Atlet Karate UNM

Atlet yang mengalami competitive anxiety tidak dapat memberikan performa yang optimal dalam bertanding, sehingga harus memiliki mental yang kuat atau mental toughness agar dapat menghadapi segala keadaan. Penelitian ini bertujuan untuk melihat apakah terdapat pengaruh mental toughness terhadap competitive anxiety pada atlet karate UNM. Hipotesis dalam penelitian ini yaitu terdapat pengaruh negatif mental toughness terhadap competitive anxiety atlet karate UNM. Metode yang digunakan dalam penelitian ini adalah metode penelitian kuantitatif. Subjek penelitian terdiri dari 53 atlet karate. Alat ukur yang digunakan yaitu skala mental toughness dan skala competitive anxiety, yang dianalisis menggunakan teknik analisis regresi linear sederhana. Hasil penelitian menunjukkan bahwa terdapat pengaruh positif antara mental toughness terhadap competitive anxiety pada atlet karate Universitas Negeri Makasar (R = 0,729; p = 0,000).

Peneliti menganggap adanya faktor lain, yaitu pengalaman bertanding yang mengganggu mental toughness atlet sehingga tidak dapat berpengaruh negatif terhadap competitive anxiety

ANALYSIS OF THE EFFECTIVENESS OF CLEAN WATER DISTRIBUTION MACHINE USING OVERALL EQUIPMENT EFFECTIVENESS (OEE) METHOD

Clean water distribution machines are very important for local drinking water companies to be able to supply clean water to customers. The need for water continues to increase, so an analysis is needed to determine the decline in engine pump performance in the production process. Maintenance activities need to be carried out to maintain the reliability (realiability) of the machine so that it can operate properly. Therefore, a good strategy is needed to maintain the continuity of the production process. The purpose of this research is to measure the performance of the water distribution pump machine / equipment associated with the low level of clean water production, to identify the losses experienced by the company. The Overall Equipment Effectiveness (OEE) value obtained before repairs were carried out in November 2019 for Lapi I was 69.38% and Lapi II was 69. 75% while in December 2019 for Lapi I it was 74.02% and Lapi II was 73.65% still below the JIPM standard, namely ≥85%. From the results of the six big losses, the clean water distribution pump machine as a whole still needs evaluation to make improvements in increasing effectiveness and productivity, especially in the problem of redeuced speed losses so that suggestions can be made to improve the clean water distribution machine. After repairs in January 2020 for Lapi I was 87.90% and Lapi II was 87.26% while in February 2020 for Lapi I it was 90.34% and Lapi II was 85.81%. From the results of the six big losses, the clean water distribution pump machine as a whole still needs evaluation to make improvements in increasing effectiveness and productivity, especially in the problem of redeuced speed losses so that suggestions can be made to improve the clean water distribution machine.
