Abstract

The intensity of solar radiation is the main factor that affects the performance of solar cells in generating electrical power. This study modeled the effect of solar radiation changes on the power output of solar panels using Matlab/Simulink, with solar radiation data from Nasa Power for the Tanjung Anom location. The simulation was carried out to measure the output power based on variations in solar radiation intensity and ambient temperature in the effective time range, namely 09.00 to 16.00. The results show that the intensity of solar radiation is directly proportional to the output power of solar panels. At the highest radiation intensity of 620.35 W/m², the maximum power produced reaches 107.6 W, with a voltage of 20.35 V and a current of 5.286 A. On the other hand, at the lowest radiation of 205.61 W/m², the power decreases to 11.94 W. The model successfully illustrates the linear relationship between solar radiation, voltage, current, and output power, and shows the sensitivity of solar panels to changes in environmental parameters. Using MATLAB/Simulink, this model can be used to design and optimize photovoltaic systems according to local conditions. This research makes an important contribution to a deep understanding of the characteristics of solar cells, as well as a reference in the development of more efficient and environmentally friendly solar energy systems.

Abstract

Genset (generator set) is a device that functions to generate electrical power. Referred to as a generator set with the understanding is a set of combined equipment from two different devices, namely the engine and generator or alternator. The engine as a rotating device while the generator or alternator as a generating device. Genset maintenance must be heated every day with a time range of 10-15 minutes for oil lubrication circulation in all parts of the engine. This is because the generator uses a battery that requires consistent battery charging. Based on the problems above, to carry out fuel efficiency in carrying out generator engine maintenance, a pump installation process design is carried out as an automatic generator oil circulation to lubricate the generator engine.

Abstract

Bureaucratic simplification is part of the national bureaucratic reform that aims to create an effective, efficient, and professional government. One form of implementation is the equalization of administrative positions into functional positions. In the Institute of Domestic Government, this policy began to be implemented in 2020 by equalizing 137 administrative positions into functional positions. However, many functional officials resulting from the equalization still have difficulty in carrying out their new duties. This study aims to evaluate the implementation of the policy of equalizing administrative positions into functional positions at IPDN. In addition, this study also identifies supporting factors, obstacles, and efforts made to overcome them using a qualitative approach and the CIPP (Context, Input, Process, Product) evaluation model developed by Stufflebeam. Data were collected through in-depth interviews, observations, and documentation, and analyzed using NVivo software. The evaluation results show that this policy has a strong foundation and supports the bureaucratic reform agenda and is relevant to IPDN's objectives, but still faces challenges in the input aspect, such as limited resources, lack of training, and inadequate work guidelines. In terms of process, policy implementation is hampered by weak coordination between units, minimal monitoring and evaluation, and low employee involvement in decision making. Although in the evaluation of this policy product it has a positive impact on employee professionalism and satisfaction, the effectiveness of its implementation is still not optimal due to mismatched tasks and increasing administrative burdens.

Abstract

This study discusses the problems in the implementation of Government Regulation Number 94 of 2021 concerning Civil Servant Discipline at the Regional Secretariat of North Sulawesi Province. Although this policy aims to strengthen the culture of ASN discipline, in its implementation there are still obstacles that have an impact on its effectiveness. The focus of the research is directed at the Implementation of Government Regulations on Civil Servant Discipline at the Regional Secretariat of North Sulawesi Province. This study uses a qualitative approach with a descriptive method. Data collection techniques are carried out through in-depth interviews, observations, and documentation studies. Data analysis is carried out interactively using the Van Meter and Van Horn policy implementation theory, which includes six main variables: policy standards and targets, resources, characteristics of implementing agents, inter-organizational communication, socio-political environmental conditions, and implementer dispositions. The results of the study indicate that the implementation of the civil servant discipline policy has not been fully optimal. Some of the obstacles found include the lack of employee understanding of the contents of the regulations, limitations in terms of policy socialization, budget limitations, and the suboptimal supporting facilities and infrastructure. In addition, communication between work units is not yet fully consistent, which has an impact on the coordination of policy implementation. The conclusion of this study is that the implementation of Government Regulation Number 94 of 2021 still needs to be strengthened through increasing human resource capacity, ongoing socialization, and consistent supervision. The researcher recommends improvements in aspects of internal communication, budget allocation for disciplinary enforcement activities, and the use of information technology to support effective policy implementation.

Abstract

The coal feeder motor is a three-phase induction motor whose speed is regulated by the Variable Speed Drive (VSD). The coal feeder motor functions as a medium for distributing coal fuel to the combustion chamber in the boiler which aims for the combustion process in heating water on the pipe wall (wall tube) which will be used as steam to drive the turbine. Before supplying coal, first pay attention to the amount of coal entering the coal feeder, because it will affect the coal flow and motor performance. The more coal that enters the coal feeder, the greater the coal flow, just as the high speed of the motor will increase the flow of coal entering the furnace. From the research results, the calculation of the change in motor speed to the torque of the coal feeder motor at a speed of 115.2 rpm obtained a torque of 7.88 Nm, at a speed of 144 rpm obtained a torque of 6.68 Nm, at a speed of 230.4 rpm obtained a torque of 5.33 Nm and at a speed of 288 rpm obtained a torque of 4.48 Nm%. at a speed of 115.2 rpm an efficiency of 31.05% was obtained, at a speed of 144 rpm an efficiency of 29.55% was obtained.

Abstract

The purpose of this study is to analyze the Strategy of the Public Works and Public Housing Agency in the Development of Special Mining Transportation Roads from Mining Business Licensing in Jambi Province. The research method uses qualitative descriptive analysis, the study uses a purposive sampling method. Data and information collection, namely observation, interviews, and questionnaires. Data validation tests carried out by researchers are by using source triangulation techniques, technical triangulation, and time triangulation. The results of the study show that 1) the long licensing process often hampers implementation. Supervision and feasibility studies exist, but high costs for land acquisition are an obstacle. The involvement of the PUPR Agency in supervision is still lacking, and government support in complex licensing also needs to be improved. To maximize implementation, there needs to be increased socialization of the benefits of special roads, simplification of the licensing process with one-stop service, and a fair compensation scheme for the community. Improving coordination between agencies and holding regular discussion forums is also very important. 2) The challenges in implementing the strategy of building special mining roads by the Public Works and Public Housing Agency in Jambi Province include five indicators: Ability, Strength, Intelligence, Opportunity, and Culture. The most important aspect is the company's ability to find funding for this project, because the Jambi Provincial Government is not involved in funding, so all costs are borne by the private sector. This creates obstacles in the implementation of the construction of special coal roads.

Abstract

Aceh Province is one of the provinces in Indonesia that is based on the implementation of Islamic law and has its own regional regulations called qanun. One of the qanuns in Aceh Province is Aceh Qanun Number 6 of 2014 concerning Jinayat Law. The desired goal of implementing the caning punishment is to reduce cases of violations of Islamic law in Aceh, but in reality violations of Islamic law still continue to occur. Therefore, it is considered important to conduct research related to the effectiveness of the caning punishment in order to provide a deterrent effect in enforcing Islamic law in Banda Aceh City. This study was conducted to analyze the effectiveness of the enforcement of the caning punishment by the Banda Aceh City government in order to provide a deterrent effect in enforcing Islamic law in Banda Aceh City, using Ryass Rasyid's theory on the main tasks of government, and using qualitative research methods with exploratory methods. Data collection techniques through purposive sampling. Data were collected through observation, interviews, and documentation studies. The results of the discussion in this study are that the enforcement of the caning punishment has not been effective in providing a deterrent effect as seen from 3 (three) aspects, namely security, order, and justice. Inhibiting factors for enforcing caning punishment are 1) Lack of human resources; 2) Lack of budget. The supporting factors are the community who participate in monitoring and reporting to the authorities if there are violations. Efforts made by the government in enforcing caning punishment in order to provide a deterrent effect can be seen from: 1) Cooperating between institutions; 2) Conducting socialization to the community; 3) Consistent with the rules that have been made. The author's suggestions or input to various stakeholders related to the implementation of the qanun jinayat in enforcing Islamic law in Banda Aceh City are as follows: 1) Adding human resources according to agency needs; 2) Increasing the budget; 3) Conducting socialization to the community regarding the understanding of the rules in force in Banda Aceh City.
