Abstract

Partikulat (PM2.5) merupakan 1 dari 7 parameter yang digunakan pada Indeks Standar Pencemar Udara (ISPU) di Indonesia. Data ini diperlukan dalam mengembangkan sebuah sistem purwarupa yang dibantu dengan Sistem Penunjang Keputusan (SPK) untuk kebutuhan pelatihan olahraga dan kesehatan. Penelitian ini bertujuan untuk mengetahui perbedaan nilai Partikulat (PM2.5) di udara antara Indoor dan Outdoor, apakah nilai PM2.5 Indoor lebih besar atau sebaliknya, dan agar didapatkan tipe data variabel dan algoritma yang sesuai dalam proses pengembangan. Penelitian ini menggunakan metode kuantitatif pada data primer yang dikumpulkan secara berdikari dengan metode pengukuran deskriptif, dan studi literatur sebagai data sekunder. Proses pengambilan sampel menggunakan teknik cluster-sampling. Didapati perbedaan nilai rata-rata partikulat PM2.5 antara indoor dan outdoor sebesar 7,27 µg/m3 dengan nilai outdoor lebih besar daripada indoor. Malam hari menjadi waktu dengan nilai partikulat PM2.5 tertinggi baik indoor (82,77±38,12 µg/m3) maupun outdoor (93,80±41,00 µg/m3), kedua nilai ini memiliki nilai standar deviasi yang cukup tinggi pula. Tipe dari sumber data adalah bilangan bulat positif, maka penggunaan tipe data numerik Integer telah seusai kebutuhan, dan pada proses pengolahan data dapat menggunakan tipe data float dengan 2 desimal. Melalui metode yang telah dilakukan secara digital-manual ini, selanjutnya dapat diotomasikan dengan perangkat mikrokontroler beserta sensor yang tersemat untuk pengembangan selanjutnya.

Abstract

Air quality is vital to be measured for indoor and outdoor situations, and this air quality relates directly to humans. Occupational Health and Safety is the efficient operation of a task that significantly influences the level of safety and comfort of a working environment. It is a health condition that aims to make the working environment obtain the highest physical, spiritual, and social health to prevent and treat diseases or health problems. This research aimed to analyze whether the PM2.5 data grabbed by the sensor in several situations, when recorded to the database, are valid to be displayed in an appropriate chart and data type when the data is shown on the dashboard. The Rain situation can reduce the PM2.5 value both Indoor and Outdoor, and in East Bekasi, Indoor PM2.5 has a lower value than Outdoor. An expert system or decision support system can be implemented for future dashboard development to show an intelligent dashboard for these Rain-No Rain and Indoor-Outdoor situations. The data from the sensor may show as an Integer data type without the decimal, but during the analysis, the data required decimal values for average, standard deviation, and PM2.5 trends. A gauge chart will be appropriate for real-time data, and a bar/line chart will be good for historical data.

Abstract

Product quality control is an important factor for the industrial world because good quality control and carried out continuously will be able to detect abnormal production results quickly, so that anticipatory action can be taken immediately. Quality is a major factor in consumer decision making before buying goods / services. The problem that occurs at this time in manufacturing companies in Indonesia is how the statistical quality control process can be applied properly. The purpose of this statistical analysis is to find out the statistical quality control process that is applied to manufacturing companies in Indonesia using bivariate control charts with copula. Copula is a function that combines a multivariate distribution function with a uniform one-dimensional marginal distribution function, in this condition the Copula used is the Archimedean Copula group. The method used in this data collection is a simple random sampling with the sample used are three manufacturing companies in Indonesia which covers the areas of Jakarta, Bandung and Makassar. The implementation of Copula in this control chart results in Frank Copula being the best Copula, this supports that the use of Copula in the quality control process has a good role

Abstract

A school library is important in education, especially in high schools to support day-to-day operations. The purpose of this community service is to develop and install a solar-powered Library Information System for the State Highschool No. 6 Cirebon (SMA Negeri 6 Cirebon), Indonesia, in which the existing library operations were done manually. First, for the library database server, a small-size Raspberry Pi is utilized with a SLiMS library automation system installed and run over the school’s local network. Then, a sufficient energy resource is required to run the computer system; in this case, to support running the Raspberry Pi device. For this, a solar panel set-up is installed at the school to generate the electric power as the renewable energy resouce. Packages of solar panels with the battery are easily found in the online Indonesian marketplace, and this made the implementation of solar energy could become faster. In addition, a series of academic seminars is also held to support the library system operation as well as the school teachers.
