Peningkatan hasil belajar materi alat-alat optik model Jigsaw pada siswa kelas X-2 semester 2 SMA Negeri 1 Muara Jawa tahun pelajaran 2014/2015

Rendahnya hasil belajar siswa kelas X-2 SMA Negeri 1 Muara Jawa Tahun Pelajaran 2014/2015 terhadap mata pelajaran kimia khususnya Materi Alat Optik, hal ini dapat ditunjukkan dari Ulangan Blok semester 2 dengan ratarata 66% dibawah ketuntasan minimal KKM 75 yang telah ditetapkan sekolah .Masih rendahnya hasil belajar tersebut kemungkinan disebabkan oleh beberapa factor antara lain: motifasi belajar siswa rendah, ruang lingkup materi yang sangat luas, pembelajaran kurang variatif, guru terlalu dominan dalam pembelajaran. Walaupun berbagai metode pembelajaran telah diterapkan (seperti ceramah interaktif, diskusi-informasi, Tanya jawab, dan penugasan), namun hasilnya belum juga menunjukkan peningkatan. Oleh karena itu perlu adanya model pembelajaran yang inovatif. Untuk permasalahan ini peneliti melakukan pembelajaran Model Jigsaw Materi Alat Optik. Penelitian ini diadakan dengan tujuan meningkatkan hasil belajar siswa, dengan indikator : Hasil belajar siswa sudah mencapai ketuntasan klasikal, dimana 85% dari jumlah siswa dalam satu kelas telah memperoleh nilai ≥75 sedangkan secara individu dinyatakan tuntas bila telah memperoleh nilai ≥75. Kegiatan penelitian ini dilaksanakan dengan dua siklus, dimana siklus memerlukan dua kali tatap muka dan siklus II juga memerlukan dua kali tatap muka. Masing masing siklus terdiri 4 tahap, yaitu : (1) Perencanaan tindakan (Planning); (2) pelaksanaan tindakan (action); (3) observasi (observation); dan (4) refleksi (reflection)

Peningkatan Motivasi dan Hasil Belajar Fisika Kompetensi Usaha, Energi dan Daya Melalui Pembelajaran dengan Pendekatan Saintifik Siswa SMK

This research aims to improve the motivation and results of learning physics effort competency, energy, and power through learning with a scientific approach for students of grade X TKRO 4 SMK Negeri 2 Wonosobo. The data collection techniques used documentation and observation techniques to process the data of observation instruments. The results showed that based on theorists through study with scientific approaches can improve the motivation of learning physics for students.

Then through learning with scientific approaches can increase the motivation to learn the physics effort competence in energy and power subject matter. Then by theoretical, that through learning with scientific approaches can improve student learning results. While based on empirical (research), apparently the highest value remains 86.67, the lowest value rises 37.06%, the average value rises 35.14% and the number of students who graduated up 41.67%, then through learning with scientific approaches can improve the results of the study of Physics effort competence, energy, and power for students. Therefore through learning with a scientific approach can improve the motivation and results of the physics learning of effort competence, energy, and power for students in grades X TKRO 4 SMK Negeri 2 Wonosobo Semester 2 years lesson 2019/2020. Findings in this study reinforce theoretical and empirical perspectives, in the teacher's effort to achieve optimal learning results.&nbsp

MOTIVASI PENGUNJUNG POLDER KOTA LAMA SEMARANG SEBAGAI RUANG PUBLIK

Kota Lama’s retention basin in Semarang is one of flood controller building which has many potentions to be developed as a public space and its already done by government. But the way of its development use as a public space, it still has several problems and need to be solved in order to make it used optimally. In another word, it requires development efforts with an involvement of its stakeholders. That will create a Kota Lama’s retention basin as a recreatif public space for the users, especially the local community as the potential one, which also as the purpose of this study. The developments efforts adapt to the public space and recreation concepts, the real conditions of Kota Lama’s retention basin, community perception as the users which analyzed with frequentive distribution and deliver alternative developments efforts. The government as managers will make a priority for the alternative based on their perception which is influenced by their competence and responsibility with analytical hierarchy process as the tools. The results are 89% community need an comfortable. Their need appear because 98% of them feel that there are only few trees and plants so the air surroundings the basin is hot. So do the government, which are tourism official, Bappeda and PT. KAI, as the manager have the same perception with the community, except public works official. They have different priority for the development of Kota Lama’s retention basin as public space, which is need a cleanliness quality improvement. And also, requires a good managements with all stakeholders involvements in a corporate framework, good coordination with transparent job and obligation for each of the stakeholders

DINAMIKA FUNGSI KEPOLISIAN DAN HUBUNGANNYA DENGAN PROGRAM PERPOLISIAN MASYARAKAT

Sejak terpisahnya institusi Polri dengan TNI, banyak pembaharuan telah dilakukan, antara lain membuat konsep pendekatan baru terhadap masyarakat dalam melaksanakan tugas penga-yoman dan pembinaan terhadap masyarakat. Dengan program POLMAS diharapkan akan tercipta sistem situasi keamanan dan ketertiban yang kondusif, karena masyarakat akan menyadari bahwa ketertiban dan keamanan itu tidak mungkin tercipta tanpa kerjasama yang sinergis antara Polri dengan masyarakat. Dalam program ini diharapkan akan tercipta keikutsertaan masyarakat dalam menanggulangi setiap ancaman, gangguan, hambatan, baik berupa pelanggaran maupun kejahatan yang akan mengganggu ketertiban dan keamanan masyarakat.Since being apart between institution of Indonesian Police (POLRI) with Indonesian National Armed Forces (TNI), there are so many renewals have been done, such as: making new approach concept prominently for sheltering and establishing society. By having this POLMAS program, it is expected to create a conducive, peaceful and orderly situation system  because society will realize that safety and orderliness situation will be impossible without any synergy cooperation between POLRI and society. It is also expected that this program will create the participation of society to cope every threat, attack, and obstacle, in the form of violation or criminal which will disturb a peaceful and orderly system of society

Determining Optimal Architecture of CNN using Genetic Algorithm for Vehicle Classification System

 Convolutional neural network is a machine learning that provides a good accura-cy for many problems in the field of computer vision, such as segmentation, de-tection, recognition, as well as classification systems. However, the results and performance of the system are affected by the CNN architecture. In this paper, we propose the utilization of evolutionary computation using genetic algorithm to de-termine the optimal architecture for CNN with transfer learning strategy from parent network. Furthermore, the optimal CNN produced is used as a model for the case of the vehicle type classification system. To evaluate the effectiveness of the utilization of evolutionary computing to CNN, the experiment will be conducted using vehicle classification datasets
