PENERAPAN IoT (Internet of Things) SMART PARKING SYSTEM DAN PENDETEKSI KEBAKARAN DENGAN FITUR MONITORING

Sistem parkir yang ada pada saat ini masih bergantung pada petugas-petugas parkir untuk mengarahkan pengemudi menuju slot parkir. Salah satunya seperti di Mall Olympic Garden Malang, dimana petugas-petugas parkir masih mengarahkan pengemudi menuju slot parkir yang masih tersedia. Selain itu, lahan parkir sering kali tidak memperhatikan kapasistas yang dimiliki oleh suatu bangunan. Selain itu, beberapa lokasi parkir masih belum terdapat sistem pendeteksi kebakaran. Bedasarkan masalah tersebut maka perlu dikembangkan sebuah sistem parkir dimana sistem tersebut dapat memberikan informasi ketersediaan slot parkir. Pengembangan sistem ini juga menambahkan sistem pendeteksi kebakaran pada area parkir karena lokasi parkir yang biasanya terletak dalam gedung dan tertutup. Sistem ini menerapkan teknologi internet of things yang diharapkan dapat menjadi solusi dari permasalahan sistem parkir. Pengujian terhadap sensor ultrasonik dilakukan dengan cara membandingkan jarak dari hasil pembacaan sensor dengan tape measurement. Hasil pengujian terhadap sensor ultrasonik pada slot parkir mendapatkan rata-rata persentase error 2.75%. Pengujian sensor MQ-7 dilakukan dengan cara membandingkan hasil pembacaan kadar kepekatan asap pada sensor dengan alat ukur Combustible Gas Detector 602, dengan rata-rata persentase error 1.60%. Pengujian sensor MQ-135 dilakukan dengan cara membandingkan hasil pembacaan kadar kepekatan asap pada sensor dengan alat ukur Combustible Gas Detector 602, dengan rata-rata persentase error yaitu 1.51%.

COMPARISON OF SCALE WEIGHTS TO TAPE ESTIMATES AND THEIR RELATIONSHIPS WITH CONDITION SCORES IN BUNAJI CATTLE

Animal weighing facilities are not available in many African farming conditions. Indirect methods of estimating animals weights have been compared with scale weights and, in some cases. condition scores. The use of calibrated weigh bands is not widely practised probably because calibrations were based on temperate breeds. A study was carried out to determine the relationship between scale, tape measurement and weighband estimates of Bunaji cattle. These were then related to the animals' condition scores. Both the tape measurement and management and research purposes. When weigh band weights significantly (P<0.001) correlated (r = 0.95 and 0.94 respectively) with the scale weight. Condition score significantly is (P<0.001) correlated with the tape meaşurement, scale and weighband weights (r = 0.62, 0.67 and 0.64 respectively). The correction factors of the regression coefficients of determining weight from condition score for the three methods varied by only 3.92. It is suggested breed. that in the absence of weighing facilities, reliable estimates can be obtained by either tape measurement or weighband methods. Condition score can also reliably be used to estimate the weight using the regression coefficients obtained. Weighbands will be easier to use in field conditions. The need to calculate the weight from a formula could introduce errors when using the tape measurement method.

Three-dimensional camera anthropometry to assess risk of cephalopelvic disproportion-related obstructed labour in Ethiopia

Cephalopelvic disproportion (CPD)-related obstructed labour requires delivery via Caesarean section (C/S); however, in low-resource settings around the world, facilities with C/S capabilities are often far away. This paper reports three low-cost tools to assess the risk of CPD, well before labour, to provide adequate time for referral and planning for delivery. We performed tape measurement- and three-dimensional (3D) camera-based anthropometry, using two 3D cameras (Kinect and Structure) on primigravida, gestational age ≥ 36 weeks, from Addis Ababa, Ethiopia. Novel risk scores were developed and tested to identify models with the highest predicted area under the receiver-operator characteristic curve (AUC), detection rate (true positive rate at a 5% false-positive rate, FPR) and triage rate (true negative rate at a 0% false-negative rate). For tape measure, Kinect and Structure, the detection rates were 53%, 61% and 64% (at 5% FPR), the triage rates were 30%, 56% and 63%, and the AUCs were 0.871, 0.908 and 0.918, respectively. Detection rates were 77%, 80% and 84% at the maximum J -statistic, which corresponded to FPRs of 10%, 15% and 11%, respectively, for tape measure, Kinect and Structure. Thus, tape measurement anthropometry was a very good predictor and Kinect and Structure anthropometry were excellent predictors of CPD risk.
