Abstract

Beton merupakan material yang hampir 60% digunakan dalam pekerjaan konstruksi dan dipadukan dengan baja. Agregat halus, agregat kasar, semen, dan air merupakan material dari beton. Mix design dan proses pengecoran sangat menentukan mutu beton. Berdasarkan hal tersebut dibutuhkan mix design dan proses pengecoran yang tepat untuk mendapatkan kuat tekan optimum. Mix design pada penelitian ini menggunakan SNI 03-2834-2000 dan SNI 7656:2012 kemudian dikombinasi dengan tiga variasi urutan pemasukan material (agregat kasar - agregat halus - semen) dan ada dua metode pemasukan air yaitu, pemasukan air di akhir langkah (dry mixing) dan  pemasukan air pada setiap langkah pemasukan material (wet mixing). Sehingga terdapat 12 variasi penelitian. Berdasarkan hasil pengujian, kuat tekan optimum yang dihasilkan adalah 43,52 MPa pada variasi penelitian P2M12 dengan proses pelaksanaan pengecoran yaitu, kerikil, semen, pasir, dan ditambahkan air pada akhir proses pengecoran (dry mixing) dan mix design yang digunakan adalah SNI 7656:2012. Jika dilihat dari nilai standar deviasi yang kecil maka dapat dikatakan hasil kuat tekan valid karena interval data tidak terlalu jauh. Namun, nilai kuat tarik yang dihasilkan tidak optimum yaitu sebesar 3,29 MPa meskipun nilai standar deviasinya kecil dan terbilang valid sedangkan untuk nilai modulus elastisitas adalah 10991,89 MPa dan nilai standar deviasi nya tinggi.

Abstract

The structure of the steel pile foundation for the Suramadu Bridge crossroad is located in a corrosive marine area. Air humidity, rainwater, mud, or friction with other objects that cause the protective layer to peel off. Corrosion monitoring is carried out to determine the corrosion rate as one of the steps to prevent corrosion. This study aims to evaluate and monitor the bridge's structure Suramadu Causeway. The evaluation carried out includes observing the damage caused by corrosion. So that it will be known the cause of corrosion and the handling of corrosion protection in the building under the bridge, this study used primary and secondary data collection methods and visual observation of damage from routine inspections carried out. The observations show that the condition of the piles is filled with marine life in the tidal area, while for areas that have never been submerged the condition is quite good. The value of the condition of the structural elements at level 3 - 5, which requires protection on steel pillars that have suffered a lot of damage—handling that needs to be done in the Atmospheric zone and Splash zone / Tidal zone is recommended Recoating, Wrapping, HDPE Jacketing, Epoxy Grouting. In the Submerged zone and the Embedded zone, it is recommended that the Cathodic Protection be replaced (120 kg for 600 mm). So from the results of the research that has been done, it can be used as a study for the maintenance of the Suramadu bridge in preventing corrosion.

Abstract

Localization and characterization of road damage are used in an effort to accelerate road repairs. The evaluation results were compared with field data and laboratory data. The results of the analysis show that the average PCI on the right side of the road reaches a value of 68 with a good rating good, on the left side it is worth 62 with a good rating good, and for the Bebonuk road section it is worth 39 with a bad rating poor. The average value of core drill is 86.85% and 99.92%, while the average PCI value is 35.36%. Asphalt content extracted with specifications 0.3, JMF 5.4% and penetration of 5.1%.

Abstract

This activity program is in partnership with the Andongsari Village Government, which is one of the villages supported by the University of Jember. The main problem in this village is the lack of knowledge and equipment that focuses on reducing the impact of flood risk, which means that flood events cannot be predicted accurately by the community. Based on these problems, the proposing team offered several solutions such as providing grants of equipment related to flood management, guidebooks for dealing with floods, training on early warning systems for flood disasters and efforts to introduce and preserve the environment. The method of implementing this activity is in several stages, which generally include: funding for equipment grants, training and simulation, mentoring, and activity evaluation. With the activities and equipment grants that have been carried out, the Village Government feels helped and has a better understanding of flood disaster risk mitigation, so that in the future it will be better prepared when facing floods

Abstract

Flooding is one of the disasters experienced by several areas in Jember Regency, especially in Ambulu District, one of which is Pontang Village. Although residents do not consider flooding as a threat because the intensity of flood events is still relatively low. However, if it is not anticipated, it will of course disrupt the activities of village communities. The aim of this activity is to provide knowledge and skills in handling the impact of flood risk to village communities and especially to the Pontang Disaster Response Village (Destana) team. This activity consists of various activities such as grants for main and supporting equipment, training and outreach, as well as activity evaluation. The result of this activity was an increase in the knowledge and skills of the village community and the Destana Pontang team regarding flood management and techniques for using the main and supporting equipment that was donated. Participants were also enthusiastic about taking part in activities organized by the implementing team, so it is hoped that this activity can be of added value for the village community and the Destana Pontang team in facing disasters in the future.Key words: Disaster Response Village, Flood AbstrakBanjir merupakan salah satu bencana yang dialami oleh beberapa wilayah di Kabupaten Jember, khususnya di Kecamatan Ambulu, yang salah satunya di Desa Pontang. Meskipun warga masyarakat tidak menganggap banjir sebagai ancaman karena kejadian banjir intensitasnya masih relatif rendah. Namun demikian apabila tidak diantisipasi, tentu saja akan mengganggu aktifitas masyarakat desa. Tujuan kegiatan ini adalah untuk memberikan pengetahuan dan keterampilan penanganan dampak risiko banjir kepada masyarakat desa dan khususnya kepada tim Desa Tanggap Bencana (Destana) Pontang. Kegiatan ini terdiri dari berbagai aktifitas seperti hibah peralatan utama dan pendukung, pelatihan dan sosialisasi, serta evaluasi kegiatan. Hasil kegiatan ini adalah adanya peningkatan pengetahuan dan keterampilan masyarakat desa dan tim Destana Pontang terkait penanganan banjir dan teknik penggunaan peralatan utama dan pendukung yang dihibahkan. Peserta juga antusias dalam mengikuti kegiatan yang diselenggarakan tim pelaksana, sehingga diharapkan kegiatan ini dapat menjadi nilai tambah bagi masyarakat desa dan tim Destana Pontang dalam menghadapi bencana dimasa mendatang.
