<![CDATA[Coronaviruses, also known as COVID-19, is a virus that attacks the respiratory system. This virus is growing very rapidly in transmission from human to human. The distribution rate in Indonesia is quite high, one of the areas exposed to COVID-19 is Bogor City. The city of Bogor occupies a moderately dangerous status, where from March 2020 to August 2021 the number of confirmed positive cases was 35,583 cases, while for patients who were confirmed positive recovered reached 35,062 people, and patients who were confirmed positive died as many as 521 people. From data obtained from the Bogor City Health Office, the daily dynamics of the COVID-19 virus continues to show an increase. The COVID-19 zoning distribution map for the Bogor City area at the kelurahan level is still not available. Therefore, this study utilizes a geographic information system (GIS) within the COVID-19 zone by applying the Kmeans Cluster method to cluster the distribution areas of the COVID-19 virus. The grouping is done based on the parameters of the number of positive cases and patients who died. This study produced a COVID-19 zoning map. Based on the test, the definite number of clusters is 3 clusters. Where the zoning division based on the COVID-19 Task Force is divided into red for the high zone, orange for the medium zone, yellow for the low zone, and areas that are not exposed to COVID-19 cases are in the green category or there are no cases. The result of this study is a COVID-19 zoning map that is displayed in WEBGIS form.]]>

<![CDATA[Air merupakan unsur paling penting dalam kehidupan manusia. Manusia memanfaatkan air untuk konsumi, mencuci, mandi dan masih banyak kegiatan lainya. Di Indonesia terdapat dua jenis sumber air, yaitu sumber air perpipaan dan sumber air non perpipaan, sumber air perpipaan dikelola oleh PDAM. PDAM masih menggunakan flowmeter analog. Bagi pelanggan PDAM flowmeter analog ini sulit diakses dan dikonversi ke dalam jumlah tagihan yang harus dibayar. Dengan sistem saat ini, petugas PDAM menghitung jumlah tagihan secara manual. Maka dari itu, dibutuhkan alat untuk memonitor penggunaan air secara realtime. Penelitian ini bertujuan untuk memonitoring volum air yang terpakai serta biaya penggunaan air secara realtime. Alat ini menggunakan microcontroller ESP32, waterflow sensor YF-S201, topology mesh untuk saling berkomunikasi secara local dan protocol MQTT untuk berkomunikasi dengan broker. Hasil pengukuran debit masih memliki error sebesar 15.5%. Rata-rata waktu yang dibutuhkan agar data yang dikirmkan dapat diterima dari 1 Node ke Node lainnya sebesar 10.3s, dengan jarak 30m atar tiap Node. Rata – rata waktu yang dibutuhkan untuk mengirim data dari Gateway ke broker adalah 3.95s.]]>

<![CDATA[Abstract Problems related to road damage are currently growing. Damages that occur are often caused by waterlogging. One of the efforts that can be done is by applying the use of porous concrete. Porous concrete can reduce water runoff and increase infiltration in the soil because it has a high porosity. As a substitute material, steel slag can be an alternative in replacing coarse aggregate. Steel slag is an abundant waste from steel production industrial companies. Currently, steel slag is widely used in high-strength concrete mixes. This study of porous concrete generally refers to ACI 522R 10. The purpose of this study was to analyze the effect of steel slag substitution on the tensile strength and permeability of porous concrete. This experimental study used two variations of the w/c (0.25 and 0.30) with two variations of crushed stone aggregate and steel slag with a diameter of 10 mm-20 mm. The tensile strength and permeability specimen of porous concrete is in the form of a concrete cylinder (15 cm diameter, 30 cm height) with 3 samples of each variation. The tests were carried out at the age of 28 days. Based on the experimental results on porous concrete with steel slag or crushed stone, the value of the tensile strength of concrete with w/c 0.30 is higher than w/c 0.25. Meanwhile, the permeability value of porous concrete in both the mixed variant of steel slag and crushed stone with w/c 0.25 is higher than w/c 0.30. So that the relationship of the tensile strength of concrete is inversely proportional to the value of the permeability of the concrete in the conditions of the two w/c (0.25 and 0.30). Keywords : porous concrete, tensile strength, permeability]]>

<![CDATA[Foam mortar is a composite material consisting of a mixture of foaming fluid, cement, sand and water. Foam mortar technology is currently being developed and can be an option for cement board mixtures that have a light weight. Foam mortar cement board is one such product. Glass fiber has a fairly high tensile strength. This makes glass fiber potential as a reinforcing material in the manufacture of cement boards. The fiberglass used is fiber with a size of 31 x 31 cm and a thickness of 0.2-0.6 mm. The purpose of this study was to obtain a cement board with a small or light density, obtain the characteristics of a cement board with foam mortar and the addition of glass fiber, and obtain the optimum content of glass fiber for maximum flexural strength and still meet the requirements of SNI 15-0233-1989. The mixture ratio is 1 PC : 1.2 PS : 0.5 foam with FAS 0.47 and variations in glass fiber content of 0%, 8%, 16%, 23%, and 31% fiber by weight of cement. The results of the analysis show that the more glass fiber used can reduce the density, increase the water content, water absorption, and increase the flexural strength up to 10 times. The highest flexural strength was found in the variation of 31% fiber and the lowest was 0% fiber with values ??of 14,931 kg/cm2 and 1,195 kg/cm2. The addition of glass fiber also increases the nailing ability of the foam cement mortar board and complies with the SNI 15-0233-1989 standard. Key words : Cement Board; Foam Mortar; Fiberglass.]]>

<![CDATA[The business trip in Telkom Education Foundantion is one of the trips that should be conducted by the staff upon the request made by the board of directors/executives/head of the institution/head of unit that includes any trip meant for duties, training, seminar, conference, comparative study, visitation, and special duty. The operational process at YPT was still using a printed letter to gain the approval, cost estimation, and the bill approval for the staff. This case brings its own disadvantage, which is human error in calculation. There should be digitalization process knowing that human error in manual processing is higher than the digitalized one. In this study, the writer discussed the design of online business trip application at YPT. A decent design along with proper implementation and accurate testing would create this website-based business trip a positive impact in giving latest innovation at YPT. This would be optimum because the writer used some supportive tools such as CodeIgniter, VS Code, PHPMyadmin, and XAMPP.]]>

<![CDATA[Analyzing the characteristic and causes of congestion in cities is the initial capital in order to determine traffic policies and appropriate management plans. One of the locations of congestion that needs to be reviewed is the intersection, because it is a meeting point of various movements from different directions. This research was conducted to analyze the performance of Simpang Empat Legundi using the PKJI 2014 method and then compared to PTV Vistro. The research began with the collection of both primary and secondary data to meet the intersection performance parameters of the store in PKJI (2014) and PTV Vistro. A comparison of the two methods is done to analyze different parameters in the analysis of the intersection performance. The results of the analysis on PKJI (2014) obtained a degree of saturation of 0.967 and a delay of 99.76 det / skr while at PTV Vistro showed a degree of saturation of 0.984 and a delay of 241.19 det / skr. The results of the analysis of both methods show the equation OF L with delay >80 det / skr Difference in value occurs due to PTV Vistro Data analysis to determine capacity, saturation degree, and delay analyzed with HCM 2010. Input values that are not in accordance with PKJI (2014) also affect the difference in the results of the analysis, including the direction of vehicle movement is not in accordance with the storage conditions, environmental conditions are considered the same every lane group i.e. CBD, and the saturated current value (S0) of 3600 which is considered the same in each lane group. Keywords : Intersection Performance; Parameters; PKJI 2014; PTV Vistro.]]>

<![CDATA[On the railway track, a change in layout and space can be found oftenly in order to improve the function of the railway to be better and have a high degree of reliability. This research aimed to analyze the slope stability due to the load that occurs when used concrete sleepers instead of gabion, as well as to find out the safety factors of hiping construction using concrete sleepers. The calculation of railway slope stability considers three models of slope failure: failure due to bolsters, shear forces, and soil bearing capacity. The calculation results of slope stability and force that occurs in the reinforcement is verified using Plaxis 2D CE V20 software with the output in the form of safety factors. Based on the results of the research, the alternative reinforcement using used concrete pads as a substitute for gabions has a deformation value of 0.1058 m with a safety factor of 1.638. So, the alternative is safe against landslides during the construction period having an FK value > 1.5 exceeding the minimum safety factor value.]]>
