In 2019 there are indication of decresed performance of Padangbai Port which can be seen from the long vehicles queues. Decline in performance is due to the high volume of vehicles unsuitable availability of facilities and infrastructure. This condition is exacerbated by the use of Padangbai Port to also serve the crossing to Nusa Penida. Damage to the pier or bad weather can also be the cause of reduced port performance. As an evaluation of the problems in 2019 and the impact of the Covid-19 pandemic in 2020, an analysis of operational performance evaluation is needed. To get ideal operational performance in the future, an analysis of the needs of ships, docks and ideal facility space is needed. The analysis is based on the prediction of the volume of passengers and vehicles by taking calculation from effect of the opening of the Banyuwangi - Lembar crossing route, which operates from 2021.
In this study, the analysis of operational performance ata Port Padangbai in serving route Padangbai – Lembar was based on the Regulation of DJPL No. HK/103/2/2DJPL-17. The prediction of passenger and vehicle volume is carried out using 4 methods whics is growth factors based on GRDP, based on population growth, based on vehicle growth and regression analysis. From the 4 prediction methods, a representative prediction result will be selected. The calculation of ideal number of ship is based on the load factor and the calculation of the ideal dock is based on the ideal BOR value. The method of calculating the ideal facility space based on KepMen Perhubungan No. KM 52 Tahun 2004.
The result show that the performance level of Port padangbai in 2020 is waiting time 13 minutes, approach time 19 minutes, ET/BT 63,42%, BOR in 2020 49% and BOR in 2019 85,74%. Prediction result of passanger and vehicle volume did not show a significant increase in the future. Result of the calculation ideal number of vessels are in 2019 26 units, 2020 19 units, 2025, 22 units, 2030 26 units, and 2040 30 units vessel. The ideal number of dock based on the calculation result show in 2019 ideally there are 3 docks, from 2020 to 2030, ideally there are 2 docks and in 2040 ideally there are 3 docks. The ideal facilty space calculation obtained the land side existing facility space is still adequate for 2019, but the availability of parking areas for crossing vehicles is prone to shortages. Meanwhile, the availability of land side facilities is currently still adequate for 2020 to 2040. The availability of water side facilities is not sufficient enough from 2019 to 2040.

Published: August 2022

ABSTRACT
In the current study, a three-pass solar air collector (SAC) connected with a stone storage bed is investigated. The thermal energy storage was used to store energy during the day time and then re-use it at night or during the cloudy hours. Four solar air collectors were used in this research which were connected consecutively to the stone storage bed. High density black stones (440 kg) of different sizes and weights were used as a storing medium. The physical properties of the stones were measured in the lab. The experiments were conducted on clear and partly cloudy days for three random days at a constant air flow rate (0.0377 kg/s) for the climate of the Dohuk city, Iraq. The parameters that affect the thermal performance of (SAC) were evaluated with integration of the stone storage bed. The solar radiation intensity, air temperatures at different locations were measured. Obtained data showed that the stone storage bed gives a temperature difference of about 10℃ after sunset and lasts for about 4-5 hours. The used stone bed has the property of acquiring stored heat for a long time after sunset which was released at night or on partly cloudy days.

Background
Dietary salt intake is an important modifiable risk factor for cardiovascular diseases. Estimation of 24-hour salt intake using morning urine samples needs to be validated in the Indian context. We examined the performance of INTERSALT, Tanaka and Kawasaki equations for the estimation of 24-hour urinary sodium from morning fasting urine (MFU) samples.

Methods
We enrolled 486 adults aged 18–69 years from four regions of India with equal rural/urban and sex representation to provide 24-hour urine samples. The next day, a MFU sample was obtained. Based on the volume and sodium content of the 24-hour urine sample, 24-hour sodium excretion (reference method) was calculated. Sodium levels in the MFU samples were measured along with other parameters required, and the above equations were used to estimate 24-hour urinary sodium levels. Intraclass correlation coefficient (ICC) was used to assess the degree of agreement between the estimates from the reference method and the three equations. Bland–Altman (BA) plots were used to identify systematic bias and limits of agreement. A difference of 1 g of salt (0.39 g of sodium) between the mean salt intake by 24-hour urine and as estimated by equations was considered acceptable.

Results
A total of 346 participants provided both the samples. The mean (SD) daily salt intake estimated by the 24-hour urine sample method was 9.9 (5.8) g. ICC was low for all the three equations: highest for Kawasaki (0.16; 95% CI 0.05–0.26) and least for Tanaka (0.12; 0.02–0.22). Only Tanaka equation provided estimates within 1 g of measured 24-hour salt intake (–0.36 g). BA plots showed that as the mean values increased, all the three equations provided lower estimates of salt intake.

Conclusion
Tanaka equation provided acceptable values of 24-hour salt intake at the population level. However, poor performance of all the equations highlights the need to understand the reasons and develop better methods for the measurement of sodium intake at the population level.

Published: August 2022

The aim of this study was to investigate the effects of different freezing and thawing methods on physical, chemical, and sensory characteristics of red shrimp (Aristaeomorpha foliacea). Shell-on and shell-off shrimps were subjected to three different freezing (blast freezing, still freezing and cryogenic freezing) and thawing (on air, in refrigerator and in microwave oven) methods and stored for 30 days at -18ºC. Quality control analyses were carried out in samples after thawing. The lowest total volatile nitrogen and trimethylamine contents, pH values and cooking losses were found in cryogenically frozen shrimp, compared with other freezing methods. However, cryogenic freezing caused colour fading and softening in texture. It was determined that microwave thawing conditions used in this study are not suitable for thawing of frozen shrimp as it negatively affects texture and colour and increases cooking loss. It was found that blast freezing, and thawing methods preserved the physical, chemical and sensory properties of shrimp better than other methods.Keywords: Aristaeomorpha foliacea; Freezing; Red shrimp; Shrimp quality
