Kajian Penggunaan Tower Tank Krembangan Pada Sistem Distribusi PDAM Surya Sembada Kota Surabaya
PDAM Surya Sembada Kota Surabaya mempunyai cakupan pelayanan sebesar 98,97% namun nilai tekanan sambungan pelanggan yang terlayani dengan tekanan lebih dari 7 meter pada tahun 2018 hanya sebesar 19,84%. Menara air dapat menaikkan tekanan dengan memanfaatkan ketinggiannya selain itu dapat digunakan untuk menyeimbangkan debit pengaliran pada area pelayanan. Sebagai upaya peningkatan kualitas air pelanggan, maka dilakukan kajian untuk mengaktifkan kembali bangunan tower tank Krembangan berkapasitas 1.500 m3 setinggi 35 m. Kajian ini mempunyai tujuan untuk menganalisis kondisi eksisting jaringan pipa distribusi jika menggunakan pompa Krembangan dalam menyuplai air, menganalisis kemampuan tower tank Krembangan dalam menyuplai air pada tahun 2030, dan menentukan sistem pengaliran yang sesuai dalam segi tekanan yang dihasilkan dan penggunaan energi listrik pompa.
Analisis jaringan distribusi menggunakan pemodelan dengan program WaterCAD V8i series5. Pemodelan jaringan distribusi dilakukan dengan beberapa parameter, yaitu debit, kecepatan, tekanan, dan biaya pengoperasian pompa. Pemodelan mengunakan data sekunder dan dilakukan untuk perhitungan kebutuhan air pada tahun 2019 dan 2030.
Dari hasil komputasi program WaterCAD untuk kondisi eksisting jaringan pipa distribusi menggunakan 4 pompa Krembangan pada tahun 2019 menghasilkan total 367 titik junction yang mempunyai nilai tekanan dibawah 10 m. Nilai tekanan kurang disebabkan karena pompa eksisting tidak dapat mengatasi fluktuasi pemakaian air pada daerah pelayanan. Pada parameter kecepatan aliran hasil komputasi menunjukan bahwa pada jam puncak nilai kecepatan cenderung tinggi yaitu kecepatan rata-rata memiliki nilai 0,53 m/s dan nilai tertinggi yaitu 2,8 m/s. Selanjutnya untuk analisis kemampuan tower tank Krembangan dalam menyuplai air pada tahun 2030, terbagi menjadi 3 trial. Hasil trial 1 dengan menggunakan tower tank menghasilkan total terdapat 63 titik junction yang mempunyai nilai tekanan dibawah 10 m. Nilai tekanan tersebut jauh lebih baik pada penggunaan tower tank daripada hanya menggunakan pompa eksisting. Nilai tekanan yang masih kecil pada junction disebabkan oleh nilai headloss yang masih tinggi. Pada trial 2 dengan memasang booster pump pada jaringan yang mempunyai nilai tekanan kecil dapat menghasilkan nilai tekanan rata-rata 17 m pada jam puncak. Dan pada trial 3 dengan pembatasan area pelayanan tower tank menghasilkan nilai tekanan rata-rata 23 m pada jam puncak. Pembatasan area pelayanan dengan mengeliminasi sub zona 305. Dari segi efisiensi energi pompa dan nilai tekanan yang paling memenuhi, trial 3 menggunakan tower tank dengan pembatasan area pelayanan merupakan alternatif terbaik dalam kajian penggunaan tower tank Krembangan.

PDAM Surya Sembada Kota Surabaya has service coverage amounted to 98.97% but the value of customer connection Pressure that is served with a Pressure of more than 7 meters in 2018 is only 19.84%. The water tower can increase Pressure by utilizing its height, otherwise it can be used to balance the discharge flowing in the service area. As an effort to improve the customer's water quality, a study was conducted to reactivate the Krembangan tower building with a capacity of 1,500 m3 and 35 m high. This study has a purpose to analyze the condition of the existing distribution pipelines when using Krembangan pumps for supplying water, analyze the ability of Krembangan tower tanks to supply water in 2030, and determine the suitable supplying system in terms of Pressure result and the use of pumped electrical energy.
Analysis of the distribution system using WaterCAD V8i modeling program series5. Distribution system modeling is carried out with using several parameters, which is flowrate, speed, Pressure, and pump operating costs.
The results of the computation with WaterCAD program for the existing condition of the distribution pipeline using 4 Krembangan pumps in 2019 produced total of 367 junction points having Pressure below 10 m. The Pressure value is below 10 m because the existing pump cannot overcome the fluctuations of water demanded in the service area. The results of the computation in parameters velocity of water show that at peak hours the velocity values tend to be high which is the average velocity has a value of 0.53 m/s and the highest value is 2.8 m/s. Furthermore, for the analysis of the ability of the Krembangan tower tank to supply water in 2030, it is divided into 3 trials. The results of trial 1 using tower tanks produced total of 63 junction points having Pressure below 10 m. The Pressure value is much better with use the tower tank than using only existing pumps. The Pressure value below 10 m at the junction is caused by headloss value is still high. Trial 2 by installing booster pumps on a distribution pipeline that has a low Pressure value can produces an average Pressure value of 17 m during peak hours. And in trial 3 with limiting the service area of the tower tank produces an average Pressure value of 23 m during peak hours. Limiting the service area by eliminating sub-zone 305. In terms of pump energy efficiency and the most comply Pressure value, trial 3 using tower tanks with limiting the service area is the best alternative in the study of the utilization of the Krembangan tower tank

Conservatism negatively predicts creativity: a study across 28 countries
Previous studies have found a negative relationship between creativity and conservatism. However, as these studies were mostly conducted on samples of homogeneous nationality, the generalizability of the effect across different cultures is unknown. We addressed this gap by conducting a study in 28 countries. Based on the notion that attitudes can be shaped by both environmental and ecological factors, we hypothesized that parasite stress can also affect creativity and thus, its potential effects should be controlled for. The results of multilevel analyses showed that, as expected, conservatism was a significant predictor of lower creativity, adjusting for economic status, age, sex, education level, subjective susceptibility to disease, and country-level parasite stress. In addition, most of the variability in creativity was due to individual rather than country-level variance. Our study provides evidence for a weak but significant negative link between conservatism and creativity at the individual level (β = −0.08, p <.001) and no such effect when country-level conservatism was considered. We present our hypotheses considering previous findings on the behavioral immune system in humans. © The Author(s) 2024
Sex Differences in Mate Preferences Across 45 Countries: A Large-Scale Replication
Considerable research has examined human mate preferences across cultures, finding universal sex differences in preferences for attractiveness and resources as well as sources of systematic cultural variation. Two competing perspectives—an evolutionary psychological perspective and a biosocial role perspective—offer alternative explanations for these findings. However, the original data on which each perspective relies are decades old, and the literature is fraught with conflicting methods, analyses, results, and conclusions. Using a new 45-country sample (N = 14,399), we attempted to replicate classic studies and test both the evolutionary and biosocial role perspectives. Support for universal sex differences in preferences remains robust: Men, more than women, prefer attractive, young mates, and women, more than men, prefer older mates with financial prospects. Cross-culturally, both sexes have mates closer to their own ages as gender equality increases. Beyond age of partner, neither pathogen prevalence nor gender equality robustly predicted sex differences or preferences across countries. © The Author(s) 2020
