PENGARUH PENGGUNAAN LIMBAH PLASTIK SEBAGAI BAHAN TAMBAH PADA CAMPURAN ASPAL LAPIS AUS AC-WC (ASPHALT CONCRETE-WEARING COURSE)
Get PDFSampah plastik merupakan jenis sampah yang menjadi ancaman serius bagi lingkungan karena selain volumenya yang terus bertambah, limbah plastik juga merupakan jenis sampah yang sulit terurai melalui proses alam. Penelitian ini dilakukan guna mengurangi keberadaan sampah dan mengetahui bagaimana pengaruh limbah plastik pada campuran aspal. Pengujian ini dilakukan di Laboratorium Universitas Islam Kalimantan Muhammad Arsyad Al Banjari. Variasi bahan tambah plastik yang digunakan adalah 3%, 6%, 9%, 12% dan 15% berjenis plastik PET (Polyethylene Terephthalate) dalam campuran aspal laston AC-WC. Metode yang digunakan adalah dengan pengujian Marshall. Terdapat pengujian berat jenis agregat kasar, agregat halus, filler dan pengujian aspal yang meliputi berat jenis aspal, penetrasi dan tiitk lembek aspal. Dari hasil penelitian maka didapat nilai kadar aspal optimum (KAO) pada campuran aspal laston AC-WC yaitu 5,75%. Dari hasil pengujian Marshall didapat nilai Stabilitas, Flow, Density, Marshall Quotient (MQ), VIM, VMA dan VFB pada setiap kadar plastik memenuhi spesifikasi campuran aspal laston AC-WC. Akan tetapi untuk VIM kadar plastik 15% tidak memenuhi spesifikasi campuran aspal laston AC-WC
STABILISASI TANAH GAMBUT MENGGUNAKAN PENAMBAHAN KAPUR DAN ABU SEKAM PADI DITINJAU TERHADAP NILAI KUAT TEKAN DAN KUAT GESER (STUDI KASUS: KECAMATAN SUNGAI TABUK, KABUPATEN BANJAR, PROVINSI KALIMANTAN SELATAN)
Get PDFPembangunan konstruksi di atas tanah gambut sering menimbulkan berbagai masalah sehingga memerlukan perhatian khusus dalam analisis daya dukungnya. salah satu alternatif yang digunakan untuk memperbaiki daya dukung dan kualitas tanah ialah dengan stabilisasi. Stabilisasi merupakan usaha dalam memperbaiki sifat fisik dan mekanik tanah, yaitu dengan penambahan zar aditif berupa kapur dan abu sekam padi. Tujuan penelitian ini untuk mengetahui nilai kuat tekan dan kuat geser tanah gambut sebelum dan sesudah distabilisasi menggunakan kapur dan abu sekam padi serta pengaruh variasi waktu pemeraman terhadap nilai kuat tekan dan kuat geser. Penambahan kapur 10%, dan abu sekam padi 5%, 10%, 15%, dengan waktu pemeraman 0 hari, 4 hari, dan 7 hari. Tanah diambil dari Kabupaten Banjar, Provinsi Kalimantan Selatan. Nilai kuat tekan bebas tertinggi terjadi pada campuran kapur 10% + abu sekam padi 15% dalam waktu pemeraman 7 hari pada titik 1 sebesar 1,786 kg/cm2 dan pada titik 2 sebesar 1,990 kg/cm2, sedangkan nilai kohesi tertinggi terjadi pada kadar campuran kapur 10% + sekam 15% dalam waktu pemeraman 7 hari sebesar 0,39 pada titik1 dan 0,35 pada titik 2, serta nilai sudut geser pada titik 1 sebesar 63,2o dan titik 2 sebesar 60,0o

DEVELOPMENT OF STRENGTH TRAINING MODELS IN CHILDREN AGED 8–10 YEARS BASED ON TRADITIONAL LOCAL GAMES IN GORONTALO PROVINCE
Get PDFThis study aims to develop a strength training model for children aged 8-10 years based on local traditional games in the form of a guidebook. This research uses the Research & Development method. This method is used to produce certain products and test the effectiveness of these products. In this research, the test subjects that will be used are children aged 8-10 years who are in the Botu Village, Dumbo Raya District, Gorontalo City. This study uses an assessment questionnaire based on the number of opinions or answers to the questionnaire with a percentage. Percentages are intended to determine the status of something that is presented and presented in the form of a percentage. Based on the results of the trial which was carried out in two stages, namely from the small group trial to the large group trial, there was a decrease in the content feasibility aspect from 90% to 84.3%, the grammar aspect from 84.16% to 81.25%, the display aspect 89.16% to 84.06%, then the total assessment results from the small group test to the large group test decreased from 88.77% to 83.78% or it could be said to be a decrease of 4.99
DESKRIPSI MOTORIK KASAR SISWA KELAS ATAS SEKOLAH DASAR DAERAH PERBUKITAN
Get PDFThe purpose of this study is related to the importance of gross motor skills in elementary school students, especially students who live in hilly areas. Gross motor is a movement of the whole body that involves large muscles such as crawling, walking, running, jumping, and throwing. This research was conducted at the 38 Nanga Tayap Public School, Ketapang Regency. The sample in the study of upper-class students (grades 4, 5, and 6) was 44 students. Data collection was taken from May 18 to May 20, 2022. Data collection was carried out using a gross motor ability test, namely TGMD-2 (run, gallop, hop, horizontal jump, leap, slide, striking). A stationary ball, stationary dribble, catch, kick, overhand throw, or underhand roll). The results showed no superior and excellent, 4.5% above the average, 47.8.% average, 22.7% below the average and 22.7% less, and 2.3 % significantly less. So it can be concluded that more than 50% of class students still have gross motor skills below the standard averag
