Namun proses pembuatan bata ini relatif sangat mahal, karena untuk mendapatkan silika harus menempuh proses produksi tambahan. Dalam penelitian ini, silika digantikan sebagian dengan memanfaatkan limbah kulit kakao yang dijadikan abu (fly ash), dimana abu kulit kakao (AKK) banyak mengandung silika. Untuk mendapatkan hasil yang optimal dari proses hidrasi semen maka AKK dikombinasikan dengan serbuk cangkang telur (SCT) yang banyak mengandung Kalsium Karbonat, sehingga terbentuk material pozolan. Untuk itu, penelitian ini bertujuan utuk menyelidiki karakteristik kekuatan tekan bata ringan CLC akibat pengaruh penambahan campuran AKK+SCT sebagai alternatif pengganti pasir silika. Sementara eksperimen ini membuat empat variasi campuran yaitu: 0% AKK dan SCT, 10% (5% AKK+5%SCT), 15% (10% AKK+5%SCT) dan 20% (15% AKK+5%SCT). Presentasi pengganti variasi campuran AKK dan SCT adalah terhadap jumlah volume pasir silika. Perbandingan pasir-semen yaitu 1:4 dengan nilai rasio air-semen sebesar 0,6. Kuat tekan didapatkan dengan menggunakan metode uji tekan beton, karena pada prinsipnya bata ringan CLC adalah sama dengan beton CLC. Pengujian kuat tekan dilakukan saat umur bata ringan mencapai 28 hari. Hasil pengujian menunjukkan bahwa proses bahan pozzolan AKK+SCT mempunyai kombinasi optimum terhadap proses hidrasi semen. Variasi 10% mempunyai nilai maksimum dibandingkan kombinasi lainnya dengan, kekuatannya meningkat sebesar 11.04% dari bata hebel konvensional. Dengan demikian campuran AKK dan SCT mempunyai potensi untuk memberikan kontribusi sebagai bahan alternatif pengganti pasir silika pada bata ringan CLC.","PeriodicalId":221886,"journal":{"name":"Jurnal MESIL (Mesin Elektro Sipil)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129436884","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}

To overcome the above situation, 80% of all machining operations are carried out with superior cutting tools such as CBN and ceramics. However, the price for the lathe chisel is still quite expensive. Cheaper carbide cutting tools are seen as a possible replacement for CBN and Ceramic insert cutting tools and are mostly processed by chemical vapor deposition (CVD) and physical vapor deposition (PVD) techniques. Therefore, a study was conducted on the performance of both PVD tools and CVD coated tools which is very important to recommend the appropriate tool for machining AISI 4340 steel. The workpiece used in this research is AISI 4340 steel (±35 HRC) and the tool used is plated PVD and CVD chisels. The tool used in this study to measure surface roughness is the Stylus Profilometer. The turning process is carried out with 8 cutting conditions using a CNC lathe. In this dry turning research, the most significant variables on surface roughness, surface roughness mathematical equations and also optimal cutting conditions were found, namely cutting speed (v) = 180 m/min, feed motion (f) = 0.2 mm/rev and depth cut (a)= 0.2mm and surface roughness (Ra)= 2.178 micron.","PeriodicalId":221886,"journal":{"name":"Jurnal MESIL (Mesin Elektro Sipil)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125447656","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}
