Abstract

This research aims to compare the time series forecasting method, namely the Fuzzy Time Series method, with Double Exponential Smoothing Holt. The data used in this study is the rainfall data of the city of Bandung every month from January 2012 to December 2021. The analysis of the two methods is seen for accuracy according to the measure of error, namely MSE (Mean Square Error) and MAD (Mean Absolute Deviation). The results show that the Fuzzy Time Series method has MSE of 15558.89 and MAD of 108.97. While the Doube Smoothing Holt method has MSE of 23367.79 and MA of 115.94 So the Fuzzy Time Series method is reliable to use for forecasting rainfall in Bandung because the error values is lower than that of the Exponential Smoothing Holt.

Abstract

Inventory of goods at large institutions is a complicated activity; one solution is to create a structured web application system that can be accessed anywhere. At the National Education Office, it is not only inventory management that is a problem but also the management of the School Operational Assistance Fund (BOS). Data security must be a priority because it involves significant funds and can be misused by irresponsible parties. This study aims to apply Two Factor Authentication to the Goods Inventory System and BOS Fund Management. The first stage is verification by the DISDIKNAS admin at each level of education. Next, a verification email will be sent to the registrant for verification. The results showed that the use of 2FA did not interfere with the performance of the web-based application or its users. The approval rate for the system is 97.4%. This research contributes to the implementation of website security and can be applied to similar systems

Abstract

The purpose of this study was to find out student errors in solving problems about mathematical literacy. This study uses a qualitative research approach with sampling method is purposive sampling. The study subjects were three students who were taken based on KAM (Student Initial Ability), namely high, medium, and low ability categories. Each subject is one person per category from the Department of Accounting, Bandung State Polytechnic. This study analyzes student errors in solving mathematical literacy problems in the statistics course for the sub-discussion of hypothesis testing. The error analysis method used is Newman analysis. This study uses two instruments, namely a test instrument with four questions in the form of descriptions and interviews. The data will then be classified into five error categories according to Newman's analysis. The conclusions in this study indicate that there are errors in answering questions, especially for mathematical literacy questions; students are expected to be able to analyze questions in the form of story questions; Understanding the problem instructions and information contained in the problem is the first step in working on mathematical literacy problems so that the level of errors and errors in working on the questions is more resolved. Of the five errors that became the standard for Newman Error Analysis assessment, three errors were made by respondents, namely errors in understanding story questions correctly, errors in transforming story questions into mathematical sentences, and errors in writing the final answer.

Abstract

Udara bersih adalah kebutuhan dasar untuk menjamin kesehatan bagi penghuni rumah. Asap rokok adalah salah satu polutan yang sering berada di rumah. Efek negatif dari asap rokok pada kesehatan telah dilaporkan oleh beberapa ahli. Namun, hingga saat ini, masih banyak dijumpai perokok yang merokok di tempat sembarang di sekitar rumah, seperti di teras, di dalam ruang tamu dan di kamar mandi. Perilaku ini akan berdampak buruk bagi kualitas udara di dalam rumah. Partikulat berdiameter kurang dari 2.5 µm (PM2.5) dan kurang dari 10 µm (PM10) adalah salah satu polutan utama yang dihasilkan oleh asap rokok. Berdasarkan beberapa penelitian, melaporkan bahwa selain akan mengendap di paru-paru, PM2.5 dan PM10 dapat menyebabkan beberapa penyakit, antara lain asma, ISPA (infeksi saluran pernafasan akut), kanker paru-paru dan meningkatkan tingkat mortalitas. Pada penelitian ini dilakukan pengukuran PM2.5 dan PM10 di dalam ruang tamu akibat perokok yang merokok di kamar mandi, di dalam ruang tamu dan di teras. Pengukuran konsentrasi PM2.5 dan PM10 dilakukan di rumah dengan luas sekitar 45 m2. Pengambilan data dilakukan sebelum merokok, 15 menit setelah rokok dinyalakan, 30 dan 60 menit setelah rokok dimatikan.  Berdasarkan pengukuran didapat bahwa konsetrasi PM2.5 dan PM10 di ruang tamu akan meningkat di atas baku mutu untuk semua lokasi merokok di area rumah. Meskipun perokok merokok di teras dengan pintu ruang tamu tertutup, konsentrasi PM2.5 dan PM10 di ruang tamu tetap meningkat, dari yang sebelumya 27 dan 68 µg/m3 menjadi 63 dan 127 µg/m3. Dari penelitian ini didapat kesimpulan bahwa meskipun merokok di luar rumah, dengan pintu tertutup, tetap dapat meningkatkan konsentrasi PM2.5 dan PM10 di ruang tamu jauh di atas di atas baku mutu. Tentu saja hal ini akan berdampak buruk bagi seluruh penghuni rumah.

Abstract

North Bandung is an area where there are several tourist attractions, including the Dago Dream Park. The main road to several locations in North Bandung is via the road in front of Terminal Dago. For this reason, the purpose of this study was to collect data on PM2.5 and PM10 concentrations at both locations, namely in front of Terminal Dago and Dago Dream Park. Data collection was carried out for seven days, from Monday to Sunday, from 08.00 to 16.00 local time. To evaluate air quality in these two places, the national standard, namely PPRI No. 22 of 2021 and international standards from WHO were applied. The measurement results show that the concentrations of PM2.5 and PM10 in these two locations are still within the national standard. Meanwhile, when evaluated with WHO standards, PM10 concentrations in both locations are still within standard, but for PM2.5, there are several days where the air quality is out of the standard. The average concentrations of PM2.5 and PM10 during the 7 days of measurement at Terminal Dago are 19.9 μg/m3 and 21.6 μg/m3, respectively. While the average concentration of PM2.5 and PM10 during 1 week of data collection were 18.9 μg/m3 and 19.9 μg/m3, respectively. This means that the concentration of PM2.5 and PM10 at Terminal Dago is slightly higher than that of at Dago Dream Park. In addition, based on an evaluation using national standards, Dago Dream Park tourist attractions still have good air quality and are safe for local residents and tourists. From the data recorded at the Health Centre (Puskesmas), the number of ARI cases in the two locations in 2020 and 2021 is relatively not much different.

Abstract

Kota Baru Parahyangan is located between Cimahi City and Padalarang. As an area designed as a satellite city, Kota Baru Parahyangan has various facilities including a business centre. In the present study, PM10 and PM2.5 will be measured at three business centres and one residential location located at the southernmost point for comparison. Data collection was carried out on 2 weekdays, namely Monday and Tuesday, and 2 weekends, namely Saturday and Sunday. The data collection time is from 08:00 to 15:30, where data collection is carried out every 30 minutes. Based on these measurements, PM10 and PM2.5 concentrations in three business centre locations and 1 residential location are still under the PPRI No. 22 of 2021 standards. Meanwhile, when evaluated using Kepmen LHK No. 14 of 2020, the API level for PM10 in three business centre locations and 1 residential location is in the "Good" category. However, the API level for PM2.5 in three business centre locations and 1 residential has reached the "Moderate" category. This means that the concentration of PM2.5 in business centre and residential in Kota Baru Parahyangan should be seriously considered by developer and local government. Because it is confirmed that PM2.5 concentrations will continue to increase over time with increasing activity and an increase in the number of vehicles passing through a region.
