This Community Service Activity (PKM) in the form of the Partnership Service Program (PPK) was carried out on a screen printing business affected by the Covid-19 Pandemic in Kebonsari, Jember Regency. The business has problems in the fields of marketing and financial management, so it requires intervention from the campus world in the form of KDP activities. The purpose of this activity is to assist screen printing business actors in sustaining their business, namely in the aspects of marketing and financial management. To overcome these problems, the activities carried out are in the form of marketing training, financial and tax management, as well as activity evaluation. The result of this activity is that the screen printing business partner has significant knowledge and skills related to aspects of marketing and financial management, so it is hoped that the sustainability of their business will improve during the current pandemic
Load and plate geometry of the bridge structure have form and nature vary. In the finite element modeling, plate weight and the load are converted to point load at the joint of the element. Research to describe plate failure is always carried out through analysis and testing in the laboratory. The aim of this research is to develop methods of analysis and testing High-Performance Fiber-Reinforced Concrete (HPFRC) plate in accordance with geometry and loading program so that the results of laboratory tests can approach the bending behavior of the actual plate element. Analysis carried out by the 2-D isoparametric finite element method, with the approach of plane strain condition. Variations performed on the supporting type, load pattern and the plate depth. Validation performed on plate specimen in the laboratory with a span length of 600 mm, width 300 mm and thickness vary from 30 mm up to 60 mm. HPFRC compressive strength is 93.045 MPa, and a splitting tensile strength is 6.018 MPa. Test performed with four-point bending pattern at a distance of 1/3 span length. Comparison results of analysis and laboratory test can be concluded that the failure of bending plate HPFRC can be described satisfactorily through finite element analysis.
Apartemen Surabaya merupakan bangunan 45 lantai yang di fungsikan sebagai apartemen dan mall dengan ketinggian total bangunan 138 m. Apartemen Surabaya terletak di Jalan Laguna Raya KJW Putih, Mulyorejo, Kota Surabaya, Jawa Timur dimana lokasi berdekatan dengan beberapa situs sesar aktif. Letak sesar aktif yaitu sesar aktif Lasem di sebelah utara dengan jarak ± 70 Km, sesar aktif Watu Kosek di sebelah selatan timur laut yang membujur dari Mojokerto hingga Madura dengan jarak ± 30 Km dan sesar aktif Pasuruan di sebelah selatan yang membujur dari Pasuruan sampai Mojokerto dengan jarak ± 50 Km. Sehingga analisis ketahanan gempa diperlukan pada gedung apartemen untuk mengetahui ketahanan terhadap gempa. Analisis dinamik menggunakan metode respon spektrum digunakan untuk menganalisa gedung. Tujuan dari penelitian ini yaitu untuk mengetahui bagaimana cara mengevaluasi struktur dengan menggunakan analisis dinamik metode respon spektrum sesuai SNI 1726:2019. Hal yang ditinjau yaitu base shear, drift dan displacement pada gedung. Hasil analisa menunjukan displacement, drift, dan base shear memenuhi syarat yang telah ditentukan. Nilai drift terbesar arah X 0.22 mm pada lt 35 dan arah Y yaitu 0.28 mm pada lt 23. Sedangkan untuk nilai displacement terbesar arah X dan Y yaitu 0.077 m dan 0.106 m.
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%.
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.
