Angklung is a musical instrument consisting of several bamboo pipes arranged vertically and tied with string or rattan, so that when it is hit or shaken it produces a different sound depending on the size and thickness of the bamboo pipe. The vibrations given will cause the resulting sound resonance. The position of the handrails and how to shake are good learning parameters for beginners in operating the angklung. Knowing the number of vibrations or beats on the angklung can provide harmonization and resonance to be played together. These conditions require measurement and observation methods with the beat density of the angklung to form synchronization and harmonization. Piezoelectric sensors and Arduino are used to read the resulting vibrations. Under the conditions of the resulting vibration will cause noise. In the process of removing noise or interference, it is carried out using the Kalman Filter algorithm. The Kalman Filter algorithm is one that is widely used for noise filtering and for estimating the state of the system. The average obtained for knocks without using Kalman Filter is 9.3 beats and for those using Kalman Filter is 7.8 for a target of 5 beats. While the results of the 20-beat target condition produce an average for sensors without Kalman Filter producing an average number of beats of 25.3 and those using Kalaman Filter produce an average value of 23.3 beats.

The research entitled " The Comparison Of Tracking Methods Using QR Code Marker And Texture Marker On Augmented Reality Application" aims to build augmented reality-based learning applications, implement tracking methods and then compare QR code markers with texture markers to determine which markers are better in augmented reality. This application displays 3-dimensional virtual objects by utilizing augmented reality technology with the help of the vuforia library, unity 3D software, and blender. Comparison of tracking methods using QR code markers and texture markers based on factors that affect the success of the application in detecting markers/detection objects. These factors are detection angle, detection distance and light intensity. Based on the results of testing on augmented reality applications with tracking methods using QR code markers and texture markers, it is known that QR Code markers can better display 3-dimensional virtual objects based on detection distance and detection angle.

This study aims to determine differences in nutrient levels in the manufacture of compost from rice straw waste with Trichoderma sp. activator. to the value of the C/N ratio and the nutrients N, P, K. The superiority of Trichoderma sp. Among others, it is easy to apply, does not produce toxins, is environmentally friendly, does not disturb organisms in the soil and does not leave residues in plants or soil. In making compost in compost tanks, the use of Trichoderma sp with a combination of ash and lime (JKAL) can increase the content of C-Organic, N-Total, Phosphorus and Potassium with respective values ??of 20.34%, 0.90%, 0 , 40% and 0.40%. The lowest C/N content was shown in the use of Trichoderma sp added with Ash (JAL) which was 22.0. In the treatment of making compost in containers, the use of Trichoderma sp with a combination of ash and lime (JKAD) was able to increase the content of C-Organic, N-Total and Phosphorus and was able to reduce the value of C/N with an average value of 19.8% respectively , 21.67%, 0.18% and 21.67%. The highest average value of Potassium (K) content shown in the JAD treatment was 0.46%.

ISO 9001;2015 Quality Management System is a quality assurance document for the stages of the process of implementing construction work activities in accordance with management rules. There are 7 ISO 9001;2015 principles, namely: 1. Customer focus, 2. Leadership, 3. Engagement and competence of people, 4. Process approach, 5. Improvement, 6. Informed decision making, 7. Relationship management. This study aims to examine the effectiveness of implementing the ISO 9001;2015 Quality Management System in fulfilling quality management requirements in the implementation of supervision on road and bridge projects in South Sulawesi province based on the seven principles of ISO 9001;2015. Data collection was carried out by interviewing, observing and distributing questionnaires to Supervision Consultant personnel in all road and bridge monitoring packages in the province of South Sulawei for the 2022 fiscal year. To analyze the effectiveness of implementing the Quality Management System ISO 9001; 2015 a quantitative descriptive approach was used and analysis used a Likert scale, the type of data used is primary data (results of interviews, questionnaires, observations) and secondary data. Based on the research results, the effectiveness of implementing ISO 9001; 2015 in project implementation is in the good category.

Employee performance must be improved continuously. To improve employee performance, an accounting information system is needed that can assist employees in completing each job and produce financial information that is used in the company's important decision-making process. This research was conducted to determine the effect of accounting information systems on employee performance at PT. Samudera Indonesia Tbk. The sample consisted of 40 employees who used an accounting information system. The analytical tools used are validity test, reliability test, Spearman rank correlation analysis, simple regression analysis, coefficient of determination, and t-test. The research results show that the accounting information system has a positive and significant effect on employee performance.

Higher education has a noble task, namely disseminating science and technology and cultural arts to all citizens with personal and institutional references to the principles of scientific methodology. Community capabilities need to be developed from various social strata by conveying the Tri Dharma of Higher Education, which is the main task of lecturers, this is a form of effort from universities to accelerate competitiveness to encourage the realization of government programs in national development. This community service activity is in collaboration with partners, namely high school and vocational schools (SMA / K) in Samarinda. The target of this program is to introduce and disseminate laboratory-based processing of plantation commodities at the Samarinda State Agricultural Polytechnic (PPNS) campus. From the results of observations in the field, there are still many high school / vocational students in Samarinda who are still not familiar with the processing technology of plantation commodities and the processing process and analysis techniques. The method of this activity is the delivery of material directly (lectures), discussion and deepening of the material by means of questions and answers, as well as simulation of laboratory-scale plantation commodity processing technology. The result of the implementation of this service is an increase in students' knowledge regarding plantation commodity processing technology and the students involved in this activity are able to master plantation commodity processing technology.
