Tetapi mempunyai kelemahan antara lain berat dan mudah pecah. Penggunaan potongan limbah ban bekas dalam campuran batako diharapkan dapat meningkatkan ketahanan batako, sehingga ringan dan tidak mudah pecah. Metode penelitian dilakukan menggunakan benda uji dinding dengan ukuran batako 34,5 x 12 x 9 cm. Campuran batako antara semen : agregat adalah 1 : 6 dengan mengunakan fas 0,6. Sedangkan kadar % volume ban bekas divariasi sebesar 50%, 55%, 60%, 65%, 70% dan 75% tehadap volume agregat. Kelecakan campuran ditingkatkan dengan penambahan superplasticizer sebesar 0,5% terhadap berat semen sehingga didapatkan campuan beton SCC. Karakteristik fisik dan mekanik dinding batako diketahui dengan melakukan pengujian berat satuan, kuat tekan, kuat lentur dan kuat geser terhadap benda uji berdasarkan SNI 03-0348-1989, SNI 03-4165-1996 dan SNI 03-4166-1996. Hasil penelitian menunjukan bahwa berat satuan batako SCC adalah sebesar 913,02 kg/m3 sehingga termasuk kategori batako ringan atau menurun 52,9% dibandingkan batako tanpa ban bekas. Sedangkan nilai kuat tekan, kuat lentur dan kuat geser dinding batako akan menurun dengan meningkatnya penambahan kadar ban bekas.","PeriodicalId":31860,"journal":{"name":"Techno","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136253141","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}

Banyumas Raya Transportation with the Buy The Service (BTS) system.. It is hoped that this mode of transportation can reduce the use of private vehicles so as to reduce the level of traffic density. The purpose of this study was to determine the level of operational performance of Trans Banyumas corridor 1 buses in terms of load factor, headway, circulation time, travel speed, downtime and availability of transport and then compared with the minimum service standards contained in the Decree of the Director General of Land Transportation Number 687 year 2002, Regulation of the Minister of Transportation of the Republic of Indonesia No. 10. Year 2012, and Regulation of the Minister of Transportation of the Republic of Indonesia No. 98. Year 2013. This research was conducted using dynamic survey methods and static surveys which were carried out on Sunday, 17 July 2022 and Wednesday, 20 July 2022 starting at 05.00 am until 09.00 pm. From the research results on the two survey days, the operational performance results for each indicator reviewed and which met the minimum service standards were circulation time, travel speed, downtime and transportation availability. Meanwhile, the operational performance indicators that have not met the minimum service standards are load factor and headway. So of the six indicators reviewed, two of them have not met the minimum service standards based on the Decree of the Director General of Land Transportation No. 687 of 2002, Regulation of the Minister of Transportation of the Republic of Indonesia No. 10. Year 2012, and Regulation of the Minister of Transportation of the Republic of Indonesia No. 98.

Energi terbarukan seperti energi potensial air dapat dikonversi menjadi energi gerak dan dalam prosesnya terjadi fluktuatif energi sehingga untuk menstabilkan energi gerak dibutuhkan fly wheel. Fly wheel yang berputar menyimpan energi inersia dan dapat diubah menjadi energi listrik. Pada penelitian ini energi yang tersimpan pada fly wheel dimanfaatkan untuk menstabilkan tegangan keluaran generator dc. Hasil pengujian dengan masa fly wheel 45.7 kg, diameter 50 cm, tegangan output generator sebesar 11.09 volt menjadi 10.22 volt atau mengalami penurunan tegangan 0.87 volt atau sebesar 7.84 %.., sedangkan pengujian pada kondisi generator tidak menggunakan fly wheel tegangan keluaran mengalami penurunan dari 21.55 volt menjadi 13.25 volt atau sebesar 38.51 %. Pengujian kestabilan tegangan generator juga mempengaruhi daya keluaran generator yaitu saat tidak menggunakan fly wheel cenderung tidak stabil, pada saat pencuplikan dari 0 -10 detik kondisi off time prime mover daya keluaran generator menurun dari 13,36 menjadi 3,81 watt ,sedangkan pada saat menggunakan fly wheel cenderung stabil, misalnya pada pengujian masa fly wheel 45,7 kg daya keluaran generator antara 6.25 sampai 6.87 watt .","PeriodicalId":31860,"journal":{"name":"Techno","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136253142","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}
