Abstract

This research is entitled 'Analysis of Implementation of Minimum Competency Assessment (SMK) Policy in Hassina Vocational High School (SMK), Sukabumi Regency'. This research is motivated by several problems that occur in the implementation of AKM at Hassina Vocational High School, Sukabumi Regency, namely: (1) the occurrence of a digital divide caused by inadequate infrastructure and internet connection speeds that vary between schools and regions (2), the problem of teacher readiness in encouraging students to face AKM, and (3) the problem of student readiness where only 8% of AKM students/participants understand the form of High Order Thinking Skills (HOTS) questions in AKM questions. The purpose of this study is to reveal and understand how the AKM policy is implemented at Hassina Vocational High School, Sukabumi Regency and the factors that can influence the implementation of the policy. The method used in this study is using a descriptive qualitative approach. The theory of policy implementation which is used as an analysis measure consists of 4 dimensions, namely: (1) communication, (2) resources, (3) disposition, and (4) bureaucratic structure. The results of this study indicate that Hassina Vocational High School as the implementer of AKM at the education unit level builds good communication with the internal environment and with implementers at the District/City level, and has good human resource availability but in terms of teacher pedagogical competence needs to be improved. As for the commitment of the organizers, school leaders continue to encourage and support the implementation of AKM to run well through improvement and refinement of the bureaucracy both at the policy and technical levels.

Abstract

Ideally, services in the library can be more attractive, friendly, fast, and accurate. This means that the orientation of library services must be based on user needs, anticipation of developments in information technology and friendly service, in other words, placing users as one of the factors. However, the results of a community satisfaction survey conducted in February 2023, the Sukabumi Regency library obtained a satisfaction index below 28 or was in the Unsatisfactory category. This study aims to analyze the effect of service quality and staff credibility on user satisfaction at the Sukabumi District Public Library. Descriptive method with quantitative approach and verification method used in this research. The research population is the average number of users from January to March 2022, with a total population of 650 users. The research sample of 388 users was selected using simple random sampling technique. The data obtained from the samples were analyzed using inferential partial least squares (PLS) analysis using the smartPLS application. The results of the data analysis show that service quality has a significant and positive influence on the credibility of officers. In addition, the credibility of officers also has a significant and positive influence on user satisfaction. Furthermore, service quality also has a significant and positive influence on user satisfaction through the credibility of officers as mediators. These findings indicate that improving and improving the quality of services provided by librarians can increase the user's perception of the credibility of the officers. In addition, the high credibility of officers can also increase user satisfaction with the services and facilities provided by the Sukabumi District Public Library. Therefore, it is suggested that libraries increase training and skills development for officers in providing the information needed by users and pay attention to other factors such as the strategic location of the library. This research contributes to the understanding of the factors that influence user satisfaction at the Sukabumi District Public Library. The results of this study can be used as a basis for improving service quality, officer credibility, and user satisfaction in an effort to improve library services as a whole.

Abstract

Electricity requirements increase every year and have become a necessity for every household in the world. Alternative electricity sources will be required to handle the need. New and renewable energy (NRE) offer divers source on this issue; however, the development of these sources demands more exploration. DSSC or Dye Sensitized Solar Cell as the third generation of Solar Cell is one of the sources that can be explored. Using Microalgae as its dye is known to be an excellent choice for alternative natural dye. Navicula TAD, the original type of Microalgae found in Ambon Bay has been proven to be able to be a catalyst in electricity flow on DSSC. This research is investigating the effect of TiO2 paste weight on the efficiency of DSSC that uses Navicula TAD as the natural dye. Early studies showed that as the weight of TiO2 paste increases, the efficiency also increases. Using TiO2 weight of 0.1; 0.3 grams, the greatest efficiency is found in the DSSC with 0.3 grams of paste. The efficiency of DSSC with 0.3 grams of TiO2 paste is 17.02%.

Abstract

Indonesia is one of the oil and gas producing countries in the world. This natural wealth needs to be utilized as much as possible. The main objective to be achieved in the production operation of an oil and gas well, is to increase the rate of production until it reaches its peak. The sharp decline in production volumes and levels of oil production from oil wells is a production problem. Paraffin is a raw material contained in crude oil and is a production problem. The paraffin deposition process can occur in perforations, tubing, flowlines, or surface facilities resulting in decreased production rates. In some cases, paraffin deposits may form at the bottom of the well and in the pore space in a radial direction several inches from the well wall, occurring as a result of the oil cooling below the cloud point. Cloud point and pour point are two things that become certain factors in the characteristics of paraffin. The cloud point is the temperature where the paraffin first begins to precipitate from the crude oil mixture. When the temperature drops, the particles that form the paraffin precipitate attract and bind other paraffin particles into one group. At this point the crude oil will start to look hazy and then can't flow. The condition where crude oil cannot flow is called the pour point. The results obtained by using the method. It can be seen that the Electric Heat Trace in the downstream area (variation 2) will be more effective because paraffin will no longer form in the flowline.

Abstract

This study is a study of power flow in an electric power system consisting of three buses which intends to find the magnitude of voltage and angles of voltage on each bus, as well as the power loss on each line. Power system modeling for power flow studies produces mathematical equations that can be solved simultaneously. One of the numerical methods to solve this problem is to use the Newton-Raphson method. To solve the power flow, the system is assumed to operate in a three-phase balanced condition and modeling is done for one phase which represents the other two phases. This requires that there are four quantities on each bus, namely active power and reactive power that enter the bus with these two quantities known on each bus. Furthermore, the magnitude of the voltage and the phase angle of the voltage at the bus, these two quantities will be calculated in the power flow study. The non-linear algebraic equation for the power flow model is linearized using the Taylor series to become a matrix equation in which there is a Jacobian matrix. This matrix equation is solved simultaneously (simultaneously) using the Newton-Raphson iteration method. Iteration results show that the value of the voltage angle of Bus-2 is 1,33 electric-degre, the angle of voltage of Bus-3 is -5,38 electric-degre and the amplitude of the voltage of Bus-3 is 0.9343-pu. Bus-1 as Swing-Bus injects active power of 99.50 MW and reactive power of 26.00 MVAr, Bus-2 as Bus-PV provides active power of 400.58 MW and reactive power of 418.57 MVAr and Bus-3 as Bus-load (PQ-Bus) receives active power of 219.00 MW from Bus-1 and 281.08 MW to fulfill a scheduled active load of 50 0.08 MW and receives 143.14 MW of reactive power from Bus-1 and 206.97 MVAr to meet the scheduled reactive power of 350.11 MVAr. There is no active power loss on each line because in the calculation the line resistance is ignored, while reactive power losses are present on each line, namely line 1-2 of 7.27 MVAr, line 1-3 of 31.36 MVAr and line 2-3 of 55.83 MVAr.
