Abstract

Jati Raya Street is one of the streets in Banyumanik district, Semarang, where many vehicles pass. Before the Covid-19 pandemic, the traffic jam usually occurs at certain hours because of people activities passing through this street. The purpose of this research is to know the degree of saturation and the street level of service from the volume / capacity ratio during New Normal condition on Covid-19 pandemic. The primary data survey is by measuring the street width and counting the two-way traffic volume. The survey was held on Monday, 9 November 2020, at 06.15 – 08.15, 11.05 – 13.05, and 16.05 – 17.05. From the survey results, the maximum traffic flow is 784 pcu/hour, the time is at 07.15 – 08.15, and the traffic direction is from Pasar Jati toward Sukun Raya street. The street capacity is 2371 pcu/hour, with a 0,33 degree of saturation. The street level of service based on this survey is B, which means, steady traffic flow, the driver has enough option to control the vehicle speed. This research was done during New Normal condition on Covid-19 pandemic, where there is a decrease on the number of vehicles that passing through this street, for some reasons, which one of them is because the school activities is using an online methods, so that students can study from home, without the needs of parents taking them to school and picking them up from school.Keywords: capacity, degree of saturation, level of service

Abstract

Abstrak Longsor merupakan suatu proses perpindahan massa batuan atau tanah akibat pengaruh gravitasi sebagai respon terhadap aktivitas alam yang menyebabkan kerusakan morfologi permukaan lereng, dan longsor yang terjadi di Wonogiri kemungkinan karena pelapukan lapisan batuan akibat curah hujan yang sering terjadi di aera tersebut. Penelitian ini dilakukan dengan tahapan pengambilan sampel batuan, pengukuran dan pengumpulan data sekunder. Klasifikasi batuan menggunakan parameter RQD, RMR dan Q-system untuk mengetahui karakteristik batuan. Hasil dari klasifikasi tersebut menunjukkan bahwa lapisan batuan di lokasi longsor masuk dalam kategori sedang hingga sangat rentan mengalami pelapukan. Dengan mempertimbangkan siklus curah hujan dan jumlah hujan dalam hari yang dihitung dalam satu tahun diketahui ada pengurangan kekuatan batuan berdasarkan penelitian terdahulu. Hasil analisa metode element hingga menunjukkan terjadi pengurangan kekuatan batuan berdasarkan parameter geser yang berakibat pada stablititas lereng batuan tersebut, dan pada tahun ke-10 diindikasikan nilai Safety Factor (SF) <1,3. Kata kunci: Kuat geser, siklus basah-kering, batuan  Abstract Landslide is a process of mass transfer of rock or soil due to the influence of gravity in response to natural activities that cause damage to the surface morphology of the slopes, and the landslide that occurred in Wonogiri was probably due to weathering of rock layers due to frequent rainfall in the area. This research was conducted with the stages of taking rock samples, measuring and collecting secondary data. Rock classification uses RQD, RMR and Q-system parameters to determine rock characteristics. The results of the classification indicate that the rock layers at the landslide location are in the moderate to very vulnerable category to weathering. By considering the rainfall cycle and the amount of rain in days calculated in one year, it is known that there is a reduction in rock strength based on previous research. The results of the finite element method analysis showed that there was a reduction in rock strength based on shear parameters which resulted in the stability of the rock slopes, and 10th year indicated the value of Safety Factor (SF) <1.3. Keywords: Landslide, wet-dry cycle, rock

Abstract

Road damage in the form of holes in flexible pavement can reduce the level of road service and endanger road users. Handling road damage requires effective maintenance methods, good pavement quality, and efficient implementation costs. This study aims to compare the quality and cost of road paving work using the Cold Paving Hot Mix Asbuton (CPHMA) method and the Macadam Penetration Layer (Lapen) method on the Bandar-Tulis Road Section, Batang Regency. The research method used is a quantitative method with data collection through field observation, laboratory testing using the Marshall method, and cost analysis based on Work Unit Price Analysis (AHSP). The quality parameters analyzed included Marshall stability values, flow values, and Marshall Quotient (MQ), while cost aspects were analyzed based on the need for labor, materials, and equipment for every 1 m³ of work. The results of the study showed that the CPHMA method had better pavement quality than the Macadam Penetration Layer method. The Marshall Quotient (MQ) value in the CPHMA method ranges from 63,114–126,562 kg/mm, which indicates the blend's ability to resist deformation and traffic loads better. In terms of implementation, the CPHMA method is more practical and efficient because it uses ready-to-use mixtures so that the work time is faster and the use of equipment is less. Based on the cost analysis, the unit price of the CPHMA method is IDR 6,616,846.56/m³, while the Macadam Penetration Layer method is IDR 2,903,370.78/m³. The cost difference between the two methods is Rp3,713,475.78/m³ or around 56.12%, so that the Macadam Penetration Layer method is more economical than the CPHMA method. Thus, the CPHMA method is superior in terms of quality and efficiency of work implementation, while the Macadam Penetration Layer method is superior in terms of cost. The selection of road patching methods needs to consider the condition of road damage, the need for traffic services, and the availability of the road maintenance budget.

Abstract

Struktur bangunan gedung terdiri dari struktur atas dan struktur bawah. Struktur atas bagian gedung yang berada di atas tanah meliputi plat, balok dan kolom. Struktur bawah bagian gedung yang berada di bawah tanah meliputi pondasi dan tie beam. Tie beam adalah bangunan di atas pondasi yang berfungsi mendistribusikan beban ke pondasi. Tie beam diperlukan untuk menahan perbedaan penurunan (differensial settlement) dan pengaku pada kolom (Sugianto, 2018). Tujuan dari kegaitan ini adalah meningkatkan kemampuan hardskill pada Siswa SMK Negeri 3 Semarang dalam perakitan atau pemasangan tulangan baja tie beam. Di SMK Negeri 3 belum memiliki mata pelajaran mengenai perakitan tulangan tie beam, sehingga perlu adanya pelatihan terkait hal tersebut. Kegiatan terdiri dari pre test, pelatihan merakit, post test. Hasil pre test menunjukan 100% peserta tidak mengetahui cara merakit tulangan tie beam, berbanding dengan hasil post test 100% peserta mengetahui cara merakit tulangan tersebut.  Dari kegiatan pelatihan ini didapatkan adanya peningkatan kemampuan merakit tulangan tie beam pada peserta.

Abstract

Volume sampah meningkat seiring dengan kemajuan suatu daerah yang berakibat jumlah laju produksi sampah sering tidak sebanding dengan proses penangananya. Hal ini tidak terlepas dari kebiasaan serta perilaku masyarakat. Permasalahan sampah bukan lagi hanya masalah kebersihan lingkungan saja, tetapi menjadi masalah sosial yang dapat menimbulkan konflik seperti di Kelurahan Tlogosari Kulon Semarang. Salah satu penyelesaianya adalah dengan pembuatan lubang biopori. Manfaat biopori selain untuk resapan air juga sebagai tempat untuk menjadikan sampah organik menjadi pupuk, dengan demikian jumlah sampah oragnik yang ada dapat dikurangi dengan kegiatan ini. Akan tetapi masih banyak masyarakat yang belum dapat membuat biopori dan pupuk kompos dari sampah organik. Oleh karena itu, kegiatan ini mendorong pemahaman masyarakat dan budaya pengolahan sampah yang tepat guna untuk menjaga kelestarian lingkungan khususnya di wilayah Kelurahan Tlogosari Kulon. Hasil dari kegiatan pembuatan biopori tersebut adalah masyarakat merasa terbantukan dalam mengolah sampah organik serta mendapatkan manfaat dari pengolahan sampah tersebut.
