Abstract

The waste tire is produced more than 10 million tons every year in the world. This problem needs serious treatment to eliminate the waste tires. This work is aimed to recycle the waste tire in concrete as a reinforcement. The contribution of the waste tires in flexural strength capacity of concrete is investigated by using experimental work and numerical simulation. Since material is quite non-homogenous compared to the pure concrete, we use six concrete beam specimens with dimension 150 mm x 150 mm x 1000 mm to get better fitting results. One specimen is non reinforced concrete beam and five specimens are waste tires reinforced concrete beam. For each of the five specimen, the waste tire reinforcement is tensioned with 0%, 17%, 25%, 40% and 60% strain before casting the concrete. The flexural strength tests are conducted after 28 days concrete ages under three point loadings. After the test, we observe that the waste tire reinforcement together with pre-stress contribute significantly on the flexural strength of the concrete beam as predicted. Finally, to support the test, finite element analysis is performed as well in this work and compared with the experimental results.

Abstract

Batako merupakan salah satu material alternatif dinding yang murah, kuat, dan mudah dalam pengerjaannya. 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.

Abstract

Sampai dengan akhir tahun 2023, target bauran energi primer energi baru terbarukan (EBT) baru mencapai 15,7%, masih memerlukan upaya yang konkrit dan terencana untuk mencapai target Bauran 23% di tahun 2025 dan 34% di tahun 2030.  Sebagai salah satu usaha ikut berkontribusi dalam pengembangan energi air maka penulis dan tim mengadakan kegiatan pengabdian masyarakat dengan tujuan memanfaatkan potensi energi listrik dari energi potensial air sepanjang aliran sungai dalam kapasitas relatif kecil yaitu 1.000 watt, disebut pikohidro, untuk penerangan jalan di grumbul Plawetan, kecamatan Tambak, Jawa Tengah. Kegiatan tersebut merupakan tahapan kedua karena pada tahun sebelumnya telah dibangun rumah pembangkit berisi turbin-generator yang ditentukan berdasar hasil pengukuran dan perhitungan kapasitas daya pada sungai yang mengaliran di daerah tersebut. Kegiatan ini dilakukan dengan tahapan: (1) membangun bendung pada aliran sungai. (2) membuat saluran air dari bendung ke rumah pembangkit, tepatnya agar energi potensial air dapat memutar turbin-generator, (3) distribusi daya listrik dari generator ke penerangan jalan umum (PJU), dan (4) pengujian nyala PJU.  Hasilnya PJU sebanyak 15 lampu LED masing-masing berkapasitas daya 15 watt dan  dummy load berupa lampu 2x200 watt dan 2x75 watt dapat menyala dengan tegangan 205 volt pada sisi beban lampu yang sesuai dengan standar PLN, yaitu SPLN 1: 1995, yakni tegangan diperbolehkan maksimum 5% dan maksimum 10% terhadap tegangan normal.  Pada tegangan nominal 220 volt maka rentang tegangan yang sesuai adalah 198 s.d. 232 volt.  Mengingat di daerah perbukitan dan distribusi sepanjang sekitar 700 meter maka digunakan kabel SR 2x10 mm2 yang menggunakan isolator XPLE dan resistansi 1,83 ohm/km panjang, sehingga dari perhitungan drop voltage yang terjadi sekitar 9,5 volt.  Dengan tercapainya tujuan kegiatan maka keamanan dan kenyamanan aktivitas warga terutama pada malam hari dapat meningkat.

Abstract

Earthquakes are natural phenomena occurring in various parts of the globe. Severe earthquakes caused substantial loss of life and property when nearly populated districts. Although some progress has been made in the area of seismic prediction, earthquakes in time, magnitude or location can not be estimated correctly. The primary method of reducing casualties is therefore to build seismic resistant structures. Current earthquakes show that the old houses, which are not intended to withstand earthquakes, have been harmed rather than the structures intended according to seismic regulations. Many current structures in Indonesia were intended only without seismic provisions to withstand the gravity loads. There is a need to study these buildings' vulnerability in order to prevent a severe danger. A Rapid Visual Screening (RVS) technique is conducted in this study to determine a Final Level 1 Score, SL1, for Jenderal Soedirman University, Indonesia’s educational facility buildings. In nine constructions situated in Purwokerto and Purbalingga, the method was implemented. Moreover, the final SL1 score is an estimate of the collapse probability if an earthquake occurs with ground motions called the maximum considered earthquake targeted risk, MCER. These score estimates are based on restricted observed and analytical information, thus the probability of collapse is therefore an approximation.

Abstract

On January 27, 2017, the Indonesian Government started building a new international airport in Yogyakarta Province, named Yogyakarta International Airport (YIA) to replace Adisucipto International Airport. YIA is located near the beach, which means that an awareness of natural disasters, such as coastal flooding, is essential. One of the causes of sea water flooding is land subsidence phenomenon. This land subsidence phenomenon can be monitored by using Sentinel-1 Interferometric Synthetic Aperture Radar (InSAR) data. To monitor the crustal deformation, the data used in this research are from years 2016-2019. The data were processed through LiCSBAS software which is published by the COMET in the UK. In the processing scheme, interferograms with many unwrapping errors are detected and removed via loop closure. Reliable time series and velocities are extracted using several noise indices, with the help of masking. The results show the subsidence phenomenon in the YIA area (up to 25 mm).
