IDENTIFIKASI POTENSI BAHAYA DAN PENGENDALIANNYA PADA PEKERJAAN BEKISTING ALUMA SYSTEM PROYEK X

Work at height is a job with a high risk of accidents, such as in the formwork aluma system. Weak supervision and a lack of knowledge of the workforce on potential hazards and risk control of the formwork aluma system are some of the causes of the high incidence of work accidents in this work. This research was conducted on the formwork aluma system of the BRI Gatot Subroto tower project, South Jakarta. The goal is to determine the potential hazards and risk control of aluma system formwork. Risk analysis is carried out using the AS / NZS 4360: 2004 standard to determine the level of risk to the potential hazards of the aluma system formwork. Potential hazards in the formwork aluma system are falling, bumping, being cut, punctured and crushed, with the level of risk being at high, substantial, medium and low levels. Risk control is carried out by the control hierarchy, namely elimination, substitution, engineering, administration, and control of PPE.

Industrial Control System Data Resiliency

This thesis identifies and fortifies against a critical vulnerability in industrial control system (ICS) security. A properly designed ICS security framework consists of a multi-layered approach starting with heavy fortifications in information technology and ending with control information of operational technology. Currently, ICS security frameworks lack visibility and place blind trust in devices at the lowest level of the control hierarchy. Attaining control data visibility at the lowest level of the control hierarchy is critical to increasing the resiliency of an ICS security posture. This thesis demonstrates how this data can be captured at the lowest level of the control hierarchy, and then synthesized with existing network and system data to form a more complete picture of operational technology’s behavior.

Pengendalian Bahaya Fisik pada Pekerjaan Dokter Gigi

Dentists are at risk of experiencing a number of occupational hazards including physical hazards. Potential physical hazards include noise, lighting, ionizing and non-ionizing radiation, percutaneous exposure incident (PEI), and extreme temperatures. Efforts to control physical hazards based on the hierarchy of hazard control in the work of dentists are substitution, engineering, administration, and the use of personal protective equipment (PPE).Keywords: physical hazards, hazard control hierarchy Abstrak: Dokter gigi merupakan salah satu profesi yang berisiko mengalami sejumlah bahaya akibat pekerjaan, termasuk bahaya fisik. Potensi bahaya fisik antara lain kebisingan, pencahayaan, radiasi ionisasi dan nonionisasi, percutaneous exposure incident (PEI), dan suhu ekstrim. Upaya pengendalian bahaya fisik berdasarkan hierarki pengendalian bahaya pada pekerjaan dokter gigi yaitu substitusi, rekayasa engineering, administrasi, dan penggunaan alat pelindung diri (APD).Kata kunci: bahaya fisik, hierarki pengendalian bahaya

Analisis Kecelakaan Lalu Lintas Yang Terjadi Pada Anak-Anak studi kasus : Daerah Istimewa Yogyakarta

Penyebab kematian terbesar pada usia sekolah dan remaja di Indonesia adalah akibat kecelakaan transportasi, disamping penyakit demam berdarah dan tuberkulosis. Berdasarkan data dari Kepolisian, angka kematian karena kecelakaan lalu lintas di Daerah Istimewa Yogyakarta selama empat tahun terakhir terus meningkat. Salah satu upaya yang dapat dilakukan untuk menurunkan angka kematian pada anak adalah dengan melakukan analisis kasus-kasus kecelakaan lalu lintas yang telah terjadi pada anak, sehingga kecelakaan yang sama tidak terulang kembali.Penelitian ini bertujuan untuk menurunkan angka kematian dan angka morbiditas anak korban kecelakaan lalu lintas di Daerah Istimewa Yogyakarta. Analisis deskriptif digunakan untuk mendeskripsikan kecelakaan lalu lintas yang terjadi pada anak, sedangkan Fault Tree Analysis digunakan untuk menentukan faktor-faktor yang mempengaruhi fatalitas dan morbiditas anak-anak korban kecelakaan lalu lintas.Hasil analisis menunjukkan bahwa faktor-faktor yang menyebabkan kematian pada kecelakaan lalu lintas yang terjadi pada anak di Daerah Istimewa Yogyakarta adalah kendaraan lain yang terlibat kecelakaan, hazard, lalu lintas yang bercampur, minimnya sarana prasarana keselamatan, melebihi kecepatan, perilaku tidak tertib dan penggunaan alat keselamatan. Upaya menurunkan angka kematian dan morbiditas pada kecelakaan lalu lintas yang terjadi pada anak di Daerah Istimewa Yogyakarta adalah dengan pendekatan Hazard Control Hierarchy, yaitu dengan Elimination berupa mencegah anak mengendarai motor dan menghilangkan hazard di pinggir jalan, Substitution berupa pemanfaatkan jasa transportasi daring, Engineering Control berupa traffic calming, pemasangan median jalan, dan pembuatan lajur khusus sepeda motor, Administrative Control antara lain dengan mengoptimalkan Forum Lalu Lintas dan Angkutan Jalan, dan Personal Protective Equipment dengan meningkatkan pemakaian alat keselamatan

Stability of intelligent energy system and intelligent control methods

In modern power systems, a variety of both objects and the tools of control is expected to be much larger than before. As a result, the dynamic properties of these systems are complicated, and the issues of maintaining stability come to the fore. The paper provides a brief overview of the types of stability, including those that, until recently, were considered local in the electric power systems of Russia. It is shown that in today’s conditions the violation of these types of stability affects the operation of the electric power system as a whole. Therefore, the coordination of control of both normal and emergency modes of the systems takes on a special role and should become more intelligent. In this regard, a brief overview of machine learning developments of control agents at different levels of the control hierarchy is presented.
