Extra toppings on a substrate made 28 days (the concrete substrate) and shear test connection 56 days of age (age 28 days connection). The type of concrete used is normal concrete where the connection does not roughened surface and without addictive substances. The study was conducted using laboratory experiments. This study uses the compressive strength of concrete plans substrate 20 MPa (NCS20) and compressive strength of concrete plans topping is 20 MPa (NCT20), 25 MPa (NCT25) and 30 MPa (NCT30). The test object cuboid with dimensions of 20x20x20cm. In the concrete susbtrate has a thickness of 12.5 cm and for concrete topping with a thickness of 7.5 cm. Each specimen consists of 3 specimens with a total of 9 specimens. Data analysis using quantitative descriptive. The results of the study obtained compressive strength in the sample substrate with a mean NCCS20 notation is 18.51 MPa. Concrete topping cylindrical samples with notation NCCT20, NCCT25, and NCCT30 obtained a mean compressive strength is 22.21 MPa, 24.39 MPa and 30.93 MPa. Shear strength test results NCST20-20 connection with the notation, NCST20-25, and NCST20-30 ie 0.44 MPa, 0.45 MPa and 0.3 MPa. Value shear test connection is influenced by several factors, such as the connection surface texture, hydration process, aggregate functions, compressive strength, porosity of concrete, slump value and watertight.Keywords: shear strength of the connection, substrate, toppingABSTRAKKajian dilakukan untuk mengetahui kuat geser sambungan beton dengan menerapkan variasi kekuatan tekan rencana pada lapis topping. Penambahan topping pada substrate dilakukan umur 28 hari (umur beton substrate) dan uji geser sambungan umur 56 hari (umur sambungan 28 hari). Jenis beton yang digunakan adalah beton normal dimana permukaan sambungannya tidak dikasarkan dan tanpa bahan zat adiktif. Kajian dilakukan dengan metode eksperimen di laboratorium. Kajian ini menggunakan kuat tekan rencana beton substrate 20 MPa (NCS20) dan kuat tekan rencana beton topping yaitu 20 MPa (NCT20), 25 MPa (NCT25), dan 30 MPa (NCT30). Benda uji berbentuk kubus dengan dimensi 20x20x20cm. Pada bagian beton susbtrate memiliki ketebalan 12,5 cm dan untuk beton topping dengan ketebalan 7,5 cm. Setiap spesimen berjumlah 3 buah benda uji dengan jumlah keseluruhan 9 buah benda uji. Analisis data menggunakan deskritif kuantitatif. Hasil dari kajian didapat kuat tekan pada sampel substrate dengan notasi NCCS20 rerata yaitu 18,51 MPa. Beton silinder sampel topping dengan notasi NCCT20, NCCT25, dan NCCT30 didapat kuat tekan rerata yaitu 22,21 MPa, 24,39 MPa dan 30,93 MPa.

This research aims to evaluate the liability of the pedestrian facilities in complying the prevailing standards and safety, health, and environment (SHE) instead of determining the priority rank for improving the performance of pedestrian facilities. This research was conducted on the pedestrian way of Malioboro area in Yogyakarta, by field survey on 23-27 January 2018. The research used questionnaires with incidental sampling technique. The data was performed and statistically analyzed by SPSS program in terms of Importance Performance Analysis (IPA) method and inference analysis using Rank Spearman's truth test. The result of this research showed that the pedestrian way had generally met the standards (57.14%) but several facilities (38.10%) did not meet the criteria and 4.76% was not available in the pedestrian way of Malioboro.The level of performance of pedestrian facilities based on SHE was mostly high (satisfied). The facilities that must be improved were the cleanliness of the pedestrian way and the toilet. Some respondences were still able to accept the conditions as follow: the speed of motor bike, the noises, street vendor layout, shop sign layout and the quality of building materials. Keywords: Environment, Importance Performance Analysis (IPA), Pedestrian way, Safety, Health ABSTRAKJalur pedestrian merupakan ruang yang memberikan layanan kepada pejalan kaki dalam melakukan aktivitasnya. Kajian ini bertujuan untuk mengevaluasi kelayakan kondisi fasilitas jalur pedestrian terhadap standar yang berlaku, safety, health, and environment (SHE), dan menentukan prioritas layanan yang diperlukan untuk peningkatan kinerja fasilitas jalur pedestrian. Kajian ini dilakukan pada jalur pedestrian Kawasan Malioboro dengan cara survey lapangan pada tanggal 23-27 Januari 2018. Kajian ini menggunakan kuesioner berskala Likert dengan teknik pengambilan sampel insidental sampling.Analisis data menggunakan analisis statistik deskriptif, metode Importance Performance Analysis (IPA) dan analisis inferensi (uji korelasi  Spearman Rank). Hasil kajian menunjukkan bahwa fasilitas jalur pedestrian telah memenuhi standarsebesar 57,14%, tetapi 38,10% tidak memenuhi kriteria dan 4,76% fasilitas tidak terdapat di jalur pedestrian kawasan Malioboro. Fasilitas yang harus ditingkatkan kinerjanya pada prioritas utama adalah tingkat kebersihan pedestrian dan toilet. Beberapa pedestrian masih dapat menerima kondisi berikut :kecepatan pengendara bermotor, kebisingan, tata letak PKL, tata letak papan nama toko dan kualitas bahan bangunan. Kata kunci: Environment, Importance Performance Analysis (IPA), Jalur pedestrian, Safety, Health","PeriodicalId":440737,"journal":{"name":"INERSIA: lNformasi dan Ekspose hasil Riset teknik SIpil dan Arsitektur","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121372659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
