Abstract

The porous asphalt mixture is a new generation of flexible pavement that is able to pass water in the upper layer (wearing course) both vertically and horizontally. The porous asphalt layer effectively provides more safety, especially when it rains to avoid aquaplaning which causes roughness of the surface to be more rough. Therefore, at this time there are many studies on the use of alternative materials to replace the limited natural materials with materials that can be utilized. The results showed that porous asphalt mixture with used tire crumb as a fine aggregate mixture had an increase in flow value of 6.32% with a decrease in stability value by 27.52% and a decrease Marshall Quotient value at 31.82%. The testing of roughness is increased by 17.71% and Mu-Meter 24.14%. This research is effective in overcoming environmental problems which include processing tire waste of 3.03 tons for 1 km of road pavement construction work.

Abstract

Abstrak: Inovasi dalam melakukan pengemasan produk menjadi salah satu upaya untuk meningkatkan nilai jual produk. Tujuan kegiatan pengabdian masyarakat adalah untuk melakukan sosialisasi diversifikasi produk kepada pelaku Usaha Mikro Kecil Menengah (UMKM). Metode pelaksanaan kegiatan sosialisasi dilakukan secara personal ke tiap-tiap rumah warga pemilik UMKM dengan tujuan menghindari kerumunan. Peserta kegiatan terdiri dari 5 Dosen kelompok wirausaha, 3 Mahasiswa Jurusan Teknik Sipil PNJ, dan mitra pengabdian yang berjumlah 20 orang pelaku UMKM di RT 004 RW 014 Jatisampurna Kota Bekasi. Hasil dari pelaksanaan kegiatan sosialisasi ditemukan lebih dari 80% peserta mengalami kendala seperti keterbatasan penguasaan teknologi informasi. Kondisi ini disebabkan karena peserta didominasi oleh warga lanjut usia, sehingga membutuhkan bantuan dan dukungan dari anak-anak mereka yang notabene generasi millenial dan tanggap teknologi. Setelah peserta memiliki produk yang berkualitas untuk dipasarkan secara luas, kami menyarankan untuk melakukan kegiatan berikutnya yaitu pelatihan dan pendampingan pembuatan sertifikat Halal MUI dan BPOM.Abstract:  Innovation in product packaging is one of the efforts to increase the selling value of the product. The purpose of community service activities is to disseminate product diversification to Small and Medium Enterprises (SME's). The method of implementing socialization activities is carried out personally to each home of the SME’s owner to avoid crowds. The participants of the activity consisted of 5 lecturers of the entrepreneurial group, 3 students of the Civil Engineering Department of PNJ, and service partners totaling 20 SME’s actors in RT 004 RW 014 Jatisampurna, Bekasi City. The results of the socialization activities found that more than 80% of the participants experienced problems such as limited mastery of information technology. This condition is because the participants are dominated by the elderly, so they need help and support from their children who are millennials and are technology-responsive. After the participants have quality products to be marketed widely, we suggest carrying out the next activity, namely training and assistance in making MUI and BPOM Halal certificates.

Abstract

In large and complex construction projects, Building Information Modelling (BIM) is important in the globalization of construction technology. Through the implementation of BIM, it is hoped that the “X” Toll Road Project can minimize errors. The problems that occurs in the field is that the QTO calculation using AutoCAD with Microsoft Excel tools in the initial estimate is less accurate so that it results in a miss calculation in the implementation, BIM is expected to be a solution to this problem. A case study was conducted to compare the quantity take-off in toll road construction on Overpass Interchange “X” and Access Roads using BIM and conventional. Data analysis was obtained from carrying out quantity take-off work using BIM and Conventional CAD as well as conducting interviews with BIM experts. Based on the research conducted, there are differences in the calculation of the take-off quantity between BIM and conventional, the percentage difference in the calculation obtained is the difference in earthworks ±4,375%, structural excavation difference ± 1,7%, pavement difference ± 4.4%, structural concrete difference ± 0.1%, and other work 0% difference. BIM can streamline more actual volume, but it takes a long time for beginners to get accurate. BIM is influenced by the level of modeling detail, if the modeling is not modeled properly, it will give wrong volume calculation results. Compared to conventional methods, using BIM at the beginning of planning is very effective in preventing re-design as well as inefficient designs and miss calculations.

Abstract

The construction field in Indonesia has been developing briskly. It can be proved by the discovery of the new method in the construction field, the Building Information Modelling (BIM) method. This BIM method is claimed to help finish the work more effective and less cost compare using the previous methods. It is because each application should be made manually and separately. Unlike the conventional method, the BIM method has the applications integrated into one, so it can accelerate the work progress and minimalize human resources. This research discusses the contrast of the construction planning process, especially when making the work method, and shop drawing, which reviewed from cost, quality, and time aspect. This research also examines the advantages and disadvantages of using the BIM method because it is categorized as a new method. The questionnaire and the interview method are used to collect the data. This research subject is the drafters and engineers already experienced in the construction field by applying the BIM method. The case of this study is Toll Road Jakarta – Cikampek II Selatan (Paket 3), with comparing the cost and time efficiency between conventional and BIM methods. The results show that the work will be done 43.82% faster using the BIM method than the conventional one. However, the required cost will be more expensive by using the BIM method because it will be allocated to invest in the software license. Keywords: Cost, Quality, and Time; Building Information Modelling (BIM); Conventional Methods.

The purpose of this study is  to determine the distribution of groundwater in the Wonorejo Village, Malang District. The method that used is the Self Potential (SP) method using leap frog configuration with 104 measurement points. The results of this study indicate the value of electric potential shown between 0-13.5 mV, and assume that a low potential value (0-1 mV) is an indication of groundwater distribution. Areas with low potential values are found in four area. The area with the lowest potential value can be used as a reference in making wells. The possibility of groundwater distribution in this research area is not in one line / flow. However, it is possible that in areas outside the research location, groundwater flow is in one lane. Thus, to prove this assumption it is necessary to carry out further research in a wider area and the use of other geophysical methods to obtain more varied subsurface information.
