Get PDFThe reseacrh of effect using Google Classroom as an LMS learning on student learning outcomes in Tondano City is an experiments carried out at several schools in Tondano City where the used of online learning platforms has been widely used by students due to the Covid-19 pandemic in 2020 in Indonesia.. This research was conducted at SMA Negeri 1 Tondano and SMA Negeri 3 Tondano with the sample chosen not randomly but with a specific aim, namely to see the equality between the control class and the experimental class. The purpose of this study was to determine the effect of using google classroom as an online learning application on student learning outcomes in Tondano City. The research method used is a quasi-experimental research with the form of nonequivalent control group design where there is one experimental group and one comparison group or control group by being given tests before and after treatment (treatment). Data on cognitive learning outcomes were analyzed using parametric statistics, namely the calculated homogeneity test, normality test, t test and N-gain, so it can be concluded that there is an effect of using Google Classroom on the learning outcomes of High School Students in Tondano Cit
BEBERAPA ALGORITMA PELABELAN GRACEFUL UNTUK GRAF CATERPILLAR
Get PDFGraceful labeling, first introduced by Rosa as β-labeling. A graceful labeling (or β-labeling) on a graph G involves assigning labels to its set of vertices, forming an injective function f that maps each vertex to the set of non-negative integers {0, 1, 2, ..., |E(G)|}, where |E(G)| denotes the number of edges in G. This induces a bijective function f* that maps the edges of G to the set of positive integers {1,2,...,|E(G)|} which the edges label obtained by absolute number of the subtraction between 2 neighboring vertex labels. One renowned conjecture proposed by Kotzig-Ringel-Rosa, known as the Graceful Tree Conjecture (GTC), posits that all trees are graceful. To this day, this remains an open problem, challenging researchers to substantiate its validity. The quest for graceful labeling, particularly for specific types of trees, continues to be an active zona of research. Notably, caterpillar graphs have been established as graceful. It is worth noting that not all graphs possess a unique labeling. For instance, in the case of graceful labeling for caterpillar graphs, there exist four distinct methods, which will be elucidated algorithmically in this article. By demonstrating various approaches to labeling caterpillar graphs, it is hoped that this concept can be extended to other graceful labelings, ultimately contributing to the identification of more graceful tree

APPLICATION OF THE INTERNET OF THINGS FOR ENVIRONMENTAL MONITORING OF GRAPE LAND
No full textThe development of information and communication technology is growing rapidly. One of the focuses of development is Internet of Things (IoT) technology. Various applications can take advantage of this technology, including telemonitoring tools in agriculture, especially the land environment on grapevines in real time and remote control. Parameters that can be monitored include Soil Humidity, Light Intensity, Air Humidity and Air Temperature. This study aims to design and build a prototype of an IoT-based vineyard environmental telemonitoring tool. This research can be applied in smart farming, especially for grape farmers. The tool is made up of 3 sensors, namely DHT11 (Humidity, Temperature), LDR (Photoresistor/Light) and YL-69 (Moisture). Arduino ESP32 kit module as a processing unit for all light, temperature and humidity variables. The processing results are displayed on the Smartphone via the Blynk application. The output of this tool can also monitor grapevines through a camera and perform watering automatically using a water pump. Based on the instrument's accuracy test which was carried out on 3 parameters of the land environment and compared to similar tools, the results of the measurement of light intensity obtained an average accuracy of 72.85%. In the temperature test, the average accuracy result is 93.75%. In the soil moisture test, the average accuracy result is 87.25%.The development of information and communication technology is growing rapidly.

DESAIN DAN PEMBUATAN TURBIN CROSS-FLOW
Get PDFTurbin secara umum dapat diartikan sebagai mesin penggerak mula di mana energi fluida kerja yang digunakan langsung memutar roda turbin, fluida kerjanya yaitu berupa air, uap air dan gas. Dengan demikian turbin air dapat diartikan sebagai suatu mesin penggerak mula yang fluida kerjanya adalah air. Pada roda turbin terdapat sudu yaitu suatu konstruksi lempengan dengan bentuk dan penampang tertentu, air sebagai fluida kerja mengalir melalui ruang diantara sudu tersebut, dengan demikian roda turbin akan dapat berputar dan pada sudu akan ada suatu gaya yang bekerja. Gaya tersebut akan terjadi karena ada perubahan momentum dari fluida kerja air yang mengalir diantara sudunya. Sudu hendaknya dibentuk sedemikian rupa sehingga dapat terjadi perubahan momentum pada fluida kerja air tersebut.
Tujuan penelitian adalah untuk mengetahui desain dan pembuat turbin cross-flow untuk trainer mikrohidro. Hasil dari penelitian ini adalah sebuah turbin cross-flow dengan ukuran jumlah sudu 18, tinggi sudu 34 mm, jarak sudu bagian dalam 11 mm, jarak sudu bagian luar, diameter luar turbin 100 mm, diameter dalam turbin 66 mm dan diameter poros turbin 19 mm
PENERAPAN MODEL PROJECT BASED LEARNING (PjBL) UNTUK MENINGKATKAN KEMAMPUAN BERPIKIR KRITIS PESERTA DIDIK PADA MATERI KOROSI
Get PDFThe development of technology in education in addition to playing a role in delivering teaching can also have a great influence and impact on students. For this reason, in today's world of education, students are expected to be able to think critically. Critical thinking as a complex process requires a high level of cognitive processing of information. This learning concept can be applied to chemistry subjects such as to corrosion materials. The study used a mixed research method involving quantitative and qualitative methods. Sample selection using purposive sampling techniques based on consideration of learning outcomes, student learning styles based on considerations. The data obtained were analyzed using Miles and Huberman data analysis techniques, and Paerson correlation. The application of the project-based learning model (PjBL) on corrosion material has been well applied so as to improve the critical thinking ability of students. In addition, there is a correlation between the application of the project-based learning model (PjBL) to the critical thinking skills of learners against corrosion materials. The test results obtained a large correlation value between syntactic variables and students' critical thinking skills of 0.991, and significance of 0.087
ANALISIS FAKTOR-FAKTOR PENYEBAB KECELAKAAN LALU LINTAS DI KABUPATEN SORONG DAN PENANGGULANGANNYA
Get PDFPenelitian ini bertujuan untuk mengetahui faktor-faktor penyebab terjadi kecelakaan lalu lintas (kecelakaan lalu lintas) di Kabupaten Sorong dan upaya yang dilakukan Satuan Lalu lintas Polres Sorong dalam menanggulanginya. Penelitian ini merupakan penelitian kualitatif. Sumber data yang digunakan yaitu data primer (hasil observasi dan wawancara langsung dengan pimpinan Satuan lalu lintas Polres Sorong) dan sekunder (laporan tertulis kecelakaan lalu lintas, peraturan perundang-undangan dan tulisan ilmiah lainnya). Data dikumpulkan melalui observasi, wawancara dan dokumentasi, setelahnya dianalisis secara deskriptif. Kami menemukan bahwa bahwa korban kecelakaan lalu lintas dominan terjadi pada pelajar laki-laki dengan korban meninggal dunia sebesar (345 kasus). Adapun faktor penyebab kecekalaan lalu lintas dikarenakan faktor: manusia, yang disebabkan karena tidak disiplin pengendara dalam berkendara misalnya mengemudi dalam keadaan mabuk; kedua, kondisi jalan yang rusak dan berlobang, yang dapat membahayakan serta minimnya lampu penerangan jalan di sebagian wilayah di kabupaten sorong; ketiga, kendaraan, dikarenakan masih banyak dijumpai kendaraan yang tidak memiliki kelengkapan spion pada motor serta kendaraan yang mengangkut material melebihi kapasitas. Untuk menangani angka kecelakaan di kabupaten sorong maka Sanlantas Polres Sorong telah melakukan beberapa upaya penanggulangan dengan cara: preventif dan represif. Preventif dengan cara memberikan penyuluhan atau sosialisasi kepada seluruh masyarakat terkait dengan aturan dalam berlalu lintas agar selalu mentaati peraturan lalu lintas guna menjaga keselamatan, sedangkan upaya represif yaitu memberikan sanksi bagi pelanggar lalu lintas dan hukuman pidana bagi pelaku dalam kecelakaan lalu lintas baik yang disengaja maupun tidak disengaja sesuai dengan peraturan yang berlaku.
