Abstract

Radiotherapy installations are among the high-risk healthcare service units due to the use of ionizing radiation in cancer treatment. Evaluating the implementation of risk management is essential to ensure the safety of patients, healthcare workers, and the surrounding environment. This study aims to evaluate the extent to which risk management has been implemented in the Radiotherapy Installation at Grandmed Hospital Lubuk Pakam in 2023. A descriptive qualitative method was used through observations, interviews with healthcare personnel, and document analysis of standard operating procedures (SOPs) and incident reports. The results of the study indicate that risk management practices have been implemented, but not yet optimally, particularly in aspects such as incident reporting and regular training. Strengthening the reporting system, continuous training, and internal audits are necessary to improve the effectiveness of risk management in the facility.This study employed a descriptive approach using qualitative methods. Data were collected through in-depth interviews with radiotherapy unit staff, direct observations, and document reviews related to the risk management system. The evaluation was conducted based on the ISO 31000 risk management standard and guidelines from the Nuclear Energy Regulatory Agency (BAPETEN).The evaluation results indicated that most hospitals have implemented the basic components of risk management, such as hazard identification, risk analysis, and risk control. However, it was found that the processes of risk monitoring and evaluation have not been carried out systematically. In addition, not all installations had complete risk documentation or conducted regular training updates.The implementation of risk management in radiotherapy installations is at a promising early stage, but improvements are still needed, particularly in the areas of documentation and the strengthening of safety culture. Strong management commitment and ongoing training are essential to enhance the effectiveness of the risk management system to ensure the safety of both patients and medical personnel

Abstract

The objectives of this study are 1) Analyze what production factors affect rice production in different strata of land area in Bengkulu Province. 2) Analyze the level of input substitution in paddy rice farming at different strata of land area in Bengkulu Province. The location determination method uses Three stages cluster sampling and the Proportionate Stratified Random Sampling sampling method, the sample number of 175 rice farmers. The data analysis method used is the cobb-douglass and MRTS production functions. 1) The results of the analysis show that only the land area factor (ha) has a real effect on production in all strata of land area. Meanwhile, in strata III and the combination of factors the use of female labor has a real effect on production, and on the combined land area the use of KCL fertilizer has a real effect on production. 2) Only the combination of male labor to female labor in Strata I is fully substituted with a substitution elasticity (ES) value greater than 1 (≥ 1) while in combination the use of fertilizer inputs is only partially substituted. Meanwhile, in strata II, III, and combined, both the combination of fertilizer inputs and male and female labor are only partially substituted.

Abstract

A new maximum power point tracking (MPPT) technique based on the bio-inspired metaheuristic algorithm for photovoltaic system (PV system) is proposed, namely tunicate swarm algorithm-based MPPT (TSA-MPPT). The proposed algorithm is implemented on the PV system with five PV modules arranged in series and integrated with DC-DC buck converter. Then, the PV system is tested in a simulation using PowerSim (PSIM) software. TSA-MPPT is tested under varying irradiation conditions both uniform irradiation and non-uniform irradiation. Furthermore, to evaluate the performance, TSA-MPPT is compared with perturb & observe-based MPPT (P&O-MPPT) and particle swarm optimization-based MPPT (PSO-MPPT). The TSA-MPPT has an accuracy of 99% and has a reasonably practical capability compared to the MPPT technique, which already existed before.

Abstract

Indirect Field Oriented Control (IFOC) is one of the vector control methods that can be applied to induction motor in the industrial world rather than Direct Field Oriented Control (DFOC) because of the flux is obtained from the formulation. However, IFOC can not guarantee the robustness and stability of the systems. Stability analysis such as Lyapunov Stability Theory can be used to make the system stable but not the robustness. Model based controller that can guarantee the stability and robustness such as sliding mode control (SMC) and fuzzy needs to be added in IFOC system to achieve proportional response system. Robust current regulator using sliding mode control was designed in this paper from state space model for model based controller. In transient response and under disturbance SMC shows better performance than PID in rising time and robustness at rotor speed and stator current.

Abstract

This study aims to examine the mechanisms and systems for restoring the right to security for former Shia adherents who have returned to their hometowns in Sampang Regency. The government must ensure the fulfillment of this right to security in accordance with its commitment to guarantee that there is no harassment or exclusion of former Shia adherents after their return. This study contributes to advancing knowledge and mechanisms for resolving Sunni-Shia conflicts, with a focus on restoring the right to security and equality. This study employs an empirical legal research method with a socio-legal research approach. The study’s findings reveal that disturbances persist, affecting the fulfillment of the right to security following the return of former Shia adherents. Such disturbances include ongoing threats of murder against former Shia adherents if they revert to their former sect. Additionally, strict surveillance by law enforcement officials and the community toward former Shia adherents—whether during religious rituals or their interactions with the general public—results in their freedom to socialize with the community and practice their faith appearing restricted, which has a psychological impact on them. Certainly, these restrictions conflict with the guarantee of religious freedom enshrined in Indonesian national law, Islamic law, and international human rights instruments. This study concludes that the government’s enforcement of the right to security has not yet been fulfilled in the post-conflict Sunni-Shia reconciliation process, and recommends further government policies to ensure the fulfillment of the right to security and the absence of excessive surveillance of former Shia adherents’ activities, particularly religious practices.
