Abstract

At present, plastic is a material that is needed by the community at large, where the impact is also very extraordinary after the plastic is used in everyday life which can cause serious problems if the management is not done properly. The problem of plastic waste does not only occur in the city of Semarang, but also in other cities, so that the Ministry of Environment and Forestry has implemented a paid plastic bag program in the short term. But this is only to deal with problems in the short term. In the long run, it will not solve the problem of "plastic waste", because the policy actually encourages people to buy plastic which, of course, will add a new burden for the community to buy it. Based on the above problems, it is necessary to utilize this plastic waste to be made into road pavement materials such as in the manufacture of Asphal Concrette Wearing Course, by making 5 mixed variations ranging from (2 to 10)% of the weight of the aggregate . This research was initiated through a survey process, material procurement, testing of stacking materials, making test specimens, testing specimens. The results of the research can show that the type of Thermosetting plastic waste has a significant influence on the Asphalt Concrete mixture AC-WC heat mixture, including: Density, Marshall Stability, Flow, VIM, VMA, MQ and the remaining Marshall Stability tend to show an increase, moderate VFA and VIMrefusal Density values tend to show a decrease. Thus the plastic waste from the Thermosetting type can be used as a partial replacement of the aggregate for the Asphalt Concrete mixture AC-WC heat mixture with a plastic waste content is limited to a maximum of 10% and at an optimum asphalt content of 5.55%. Thus this research is expected to be of benefit to the industry and the people of Semarang in relation to the use of plastic waste for road pavement.

Abstract

Supplier tidak dapat dipisahkan dari dunia konstruksi. Kedatangan material dapat mempengaruhi risiko keterlambatan dalam proyek konstruksi. Penelitian ini bertujuan guna mengetahui risiko yang ditimbulkan jika material tidak datang sesuai dengan jadwal yang sudah ditentukan terhadap proyek konstruksi dan cara yang efektif untuk mengatasinya. Penelitian ini dilakukan dengan cara mengobservasi proyek konstruksi yang mengalami gangguan karena keterlambatan pengiriman material. Hasil penelitian menunjukan bahwa keterlambatan pengiriman dapat meningkatkan risiko terhadap keterlambatan dari sebuah proyek konstruksi. Untuk dapat mencegah keterlambatan sebuah proyek konstruksi, cara yang paling efektif adalah dengan mempercepat dan mengusahakan pelaksanaan pekerjaan sesuai dengan rencana.

Abstract

Alat Penekuk begel adalah alat untuk membengkokkan besi tulangan dalam berbagai macam sudut sesuai dengan perencanaan. Cara kerja alat ini adalah besi yang akan dibengkokkan dimasukkan di antara lubang tekan dan poros pembengkok kemudian diatur sudutnya sesuai dengan sudut bengkok yang diinginkan dan panjang pembengkokkannya. Berkembangnya PGOT (pengemis, gelandangan dan orang terlantar) diduga akan berdampak memberi peluang munculnya gangguan keamanan dan ketertiban di masyarakat, yang pada akhirnya dapat mengganggu stabilitas sehingga pembangunan akan terhambat. Panti PGOT Mardi Utomo Semarang adalah Unit Pelaksana Teknis pada Dinas Sosial Provinsi Jawa Tengah yang memiliki tugas pokok dalam melaksanakan sebagian kegiatan teknis operasional di bidang pelayanan dan rehabilitasi sosial. Tujuan kegiatan pelatihan ini adalah untuk mendeskripsikan peran pekerja sosial dalam peningkatan kualitas hidup masyarakat di Panti PGOT Mardi Utomo serta faktor pendukung dan menemukan solusi yang menghambat pelaksanaan rehabilitasi sosial. Toko Besi AMAN yang beralamat di Jalan Setiabudi Banyumanik merupakan toko yang menyediakan bahan dan peralatan pelatihan. Selama ini tenaga terampilnya diperoleh dari luar Semarang sehingga tidak efisien untuk pengusaha itu sendiri, karena harus menyediakan penginapan untuk tenaga kerjanya. Jika masyarakat di Panti PGOT Mardi Utomo Semarang bisa banyak tenaga terampil pertukangan, maka pemilik Toko Besi AMAN mudah mendapatkan tenaga kerja dari Semarang.

Abstract

Rigid pavement work on the XYZ Road Construction Project experienced a problem, namely the occurrence of cracks in the rigid pavement structure above the box culverts under which soil improvement was carried out using embankment soil. The purpose of this study is to analyze the factors that cause settlement of the embankment that causes the rift of the rigid pavement structure on box culverts built on embankment soil so that the results can be used as a reference for handling or repairing rigid pavement work on box culverts with a structure piled up soil in subsequent segments. From the results of the analysis it can be seen that the process of casting rigid pavement was carried out at two points, namely Point 1 and Point 2 where after casting the rigid pavement, the subgrade beneath it still experienced a decrease of 10 mm and 6 mm. This decline occurred for up to 3 months and caused cracks in the rigid pavement structure above it. This is due to the difference in settlement of the box culvert which was initially assumed not to have decreased again with the surrounding embankment which was still experiencing settlement. In addition, the results of the analysis show that the rigid pavement design uses a single reinforcement so that the capacity of the concrete (Mu) is less than the weight of the concrete itself which causes the concrete to crack.
