Abstract

In structural engineering applications, the limit of building deflection or interstory drift is an important issue. In high-rise buildings that are more than or equal to 60 floors in the current era, systems are used in the structure of the building. The function of the Belt Truss is to reduce the deflection that occurs in the building by converting the building's overturning moment into the axial force of the exterior column. The Belt Truss structure itself can use reinforced concrete structures and steel structures. Because the Belt Truss structure is an innovation in the world of structural engineering, the parameter values for earthquake loads are not listed in the applicable Building Planning Standards. The standard for earthquake-resistant building regulations requires the parameters of Response Modification Factor (R), Overstrength Factor (Ωo), and Deflection Magnification (Cd) for determining earthquake loads. Because the parameters on the Belt Truss structure are not listed in the Standard for Earthquake Resistant Building Regulations, a study of the earthquake load parameters on the Belt Truss structure was carried out. The method used in this research is a literature study using Pushover Load Analysis according to ATC - 40 and FEMA 356. Keywords: Belt Truss, Dual System; ATC – 40; FEMA 356; Response Modification Factor (R); Overstrength Factor (Ωo); and Deflection Magnification (Cd) AbstrakDalam aplikasi rekayasa struktur gedung, batasan defleksi bangunan atau interstory drift adalah masalah penting. Pada bangunan tinggi yang lebih dari atau sama dengan 60 lantai pada era sekarang sudah menggunakan sistem pada struktur bangunan tersebut. Fungsi dari Belt Truss tersebut berguna untuk mengurangi defleksi yang terjadi pada bangunan dengan mengkonvesi momen guling bangunan menjadi gaya aksial kolom eksterior. Struktur Belt Truss sendiri materialnya bisa menggunakan struktur beton bertulang dan struktur baja. Karena struktur Belt Truss merupakan inovasi pada dunia rekayasa struktur, maka nilai parameter beban gempa tidak tercantum pada Standar Peraturan Perencanaan Bangunan yang berlaku. Standart Peraturan Bangunan tahan gempa diperlukan parameter – parameter Faktor Modifikasi Respon (R), Faktor Kuat Lebih (Ωo), dan Perbesaran Defleksi (Cd) untuk penentuan beban gempa. Dikarenakan parameter pada struktur Belt Truss tidak tercantum pada Standar Peraturan Bangunan Tahan Gempa, maka dilakukan penelitian parameter-parameter beban gempa pada struktur Belt Truss tersebut. Metode yang digunakan dalam penelitian ini adalah studi literatur dengan menggunakan analisa Beban Dorong Pushover Analysis sesuai ATC - 40 dan FEMA 356.

Abstract

Penelitian ini memiliki tujuan untuk mengetahui adanya peningkatan hasil belajar chest pass peserta didik dalam bola basket menggunakan pendeketan permainan. Metode penelitian ini mengunakan penelitian tindakan kelas (PTK). Subyek dalam penelitian ini adalah peserta didik kelas XI IPS 2 SMA Negeri 3 Jombang. Metode pengumpulan data menggunakan observasi dan pengukuran dan alat pengumpulan data berupa lembar observasi dan melakukan tes. Hasil dari penelitian ini menampilkan bahwa menggunakan metode pendekatan permainan dapat meningkatkan hasil belajar chest pass permainan bola basket, yaitu nilai ketuntasan sebelum mendapatkan pendekatan permainan yaitu 33,3% atau hanya 11 peserta didik yang tuntas dan 22 peserta didik tidak tuntas atau sebesar 66,7%, setelah menggunakan metode pendekatan permainan pada siklus I peserta didik yang tuntas sebanyak 20 peserta didik atau 60,6% dan 13 peserta didik belum tuntas atau sebanyak 39,4%. Siklus II dengan menerapkan metode yang sama peningkatan kembali terjadi menjadi 81,8% atau 27 peserta didik yang tuntas dan 18,2% atau 6 peserta didik tidak tuntas. Kesimpulannya, metode pendekatan permaianan pada bola basket dapat meningkatkan hasil belajar peserta didik.

Abstract

Purpose): This study aims to review the conformity of the implementation of financial report audit planning carried out by the XYZ Public Accountant Office with auditing standards, and get an overview of how good audit planning practices are considering the risk and management aspects of the engagement are taken into account. Methodology: The method used is descriptive qualitative combining literature studies and field studies. Public Accountant Office (KAP) XYZ (pseudonym) domiciled in Tangerang was used as the object of the case study. Results: The results show that the policies and procedures for planning audits of financial statements at KAP XYZ are generally in accordance with auditing standards and pay attention to risk, but due to time and cost factors there are exceptions to the involvement of members in planning and the use of specialists in conducting audits. Limitations: The limitations of this study are the relatively short field period, by only focusing on the study on the audit planning stage. Contribution: This study can be a comparison for auditors and KAPs, especially how the stages of planning activities are carried out, knowing their weak points (for example in the case that team members are not optimally involved in planning, even though they are executors of the audit program). In general, the study is also useful scientifically, namely linking aspects of management (management) with auditing practices at the planning stage.

Abstract

Colomadu District is one of the districts located in Karanganyar Regency, Central Java Province. It is projected that the economy in this area will grow through business sectors such as goods and services, tourism, and industry, thus the construction of a Dormitory Building is planned in the area. Considering its proximity to Yogyakarta Province, which frequently experiences earthquakes, earthquake-resistant buildings are necessary to reduce the risk of casualties and material losses. Therefore, the design of this building utilizes a Special Moment Resisting Frame (SRPMK) system. The building with SRPMK is designed with the concept of SCWC (Strong Column and Weak Beam), where the column elements are stronger than the beam elements. This design aims to create a structural system that can withstand seismic forces, in accordance with SNI 2847:2019 requirements. Seismic force loading is analyzed using the response spectrum method, and the structural calculations are performed using ETABS V9.7.4 software. From the planning results, the dimensions obtained include a Bondek floor slab thickness of 130 mm, beam dimensions B1A 150x400 mm, B2A 200x400 mm, B2B 200x400 mm, B2C 200x400 mm, B2D 200x400 mm, B2E 200x400 mm, B3A 200x500 mm, B3B 200x500 mm, B4A 300x150 mm, B5A 300x150 mm, BS 150x300 mm, and column dimensions KP 150x150 mm, K1A 200x300 mm, K2A 400x550 mm, K3A 450x650 mm, and K4 350x500 mm.
