Important role in the comfort of patients. Based on field observation, patients and visitors felt uncomfortable and bored while waiting in the queue to consult a doctor. Hospital visitors are not all ill patients but there are also those who only consult, escort, or visit. In this case, the beauty and comfort in the waiting area, which is a public and intermediary area, is expected to have a psychological effect that can distract visitors from a terrifying impression, provide comfortability while waiting and reduce patient tension before being examined. This study examines the influence of interior on the comfort of patients in the waiting room with case studies at Abby Hospital, Bunda Women and Children Hospital, and PMI Hospital. This study uses a qualitative method with a correlation method approach. Research variables include (1) circulation, (2) cleanliness, (3) noise, (4) lighting, (5) beauty, (6) aromas/odors. The findings show that at Bunda Women and Children Hospital, 32% of the respondents felt uncomfortable with the layout of the room (facilities/furniture), 64% of respondents felt comfortable, 4% of respondents felt very comfortable. While at PMI Hospital, 36% of respondents felt uncomfortable with the layout of the room (facilities/furniture), 56% of respondents felt comfortable, 4% of respondents felt very comfortable. Finally, at Abby Hospital, 0% of respondents felt uncomfortable with the layout of the room (facilities/furniture), 68% of respondents felt comfortable, 32% of respondents felt very comfortable. In this study, conclusions were drawn for basic guidelines for hospital comfort in terms of advantages and disadvantages.

Acid sulphate soils (ASS) had low pH, low nutrients availability and also soluble aluminium and iron were high. Inoculum of sulphate reducing bacteria (SRB) which organic matter as media could increased the soil pH, nutrient content and decrease sulfur-total of acid sulfate soils. The research was conducted in a randomized block design with two replications. This study used a randomized block design with two factors and two replications. The first factor was compost inoculum (C) was taken ten treatments from without any inoculum SRB and 9 treatment with different types and dosages of organic matter as media. The second factor was the water content condition (K) namely of K1: 100% field capacity and K2: 110% field capacity. Different types and dosages of organic matter appear to influence the changes in soil properties (tends to decrease soil sulfate and increase soil pH, and nutrient content levels in soil and plant). Inoculum SRB of palm oil empty bunches and weed gave a higher sulfate reduction compared to C0 (without inoculums) or inoculums with carrier media that used rice straw in water content 100% or 110% field capacity (FC).

The configuration of new type of turbine is the Archimedes wind turbine with a spiral structure whose design is inspired by logarithmic spirals. This type of wind turbine uses lift and drag to harness the kinetic energy of the wind. The eccentric design has aerodynamic characteristics that have been the focus of previous research. The design is made from the arrangement of the Fibonacci sequence (1x1, 2x2, 3x3, 5x5, 8x8) or commonly known as the golden ratio. This study aims to analyze the coefficient of lift (CL) and coefficient of drag (CD) with variations opening angle of 35Â°, 45Â°, 65Â°, air fluid, turbulent flow, Re 1200, pressure distribution 1 atm, wind speed 5, 5 and 15 m/s. The results is at wind speed of 5.5 m/s, an angle of 35Â°, the CL value is 1.07E+02, the CD value is 4.02E+04. At wind speed of 5.5 m/s, an angle of 45Â°, the CL value is 1.08E+04, the CD value is 1.77E+01. At wind speed Â of 5.5 m/s, an angle of 65Â°, the CL value is 1.84E+06, the CD value is 3.68E+04. At wind speed Â of 15 m/s, an angle of 35Â°, the CL value is 2.20E+03, the CD value is 9.76E+02. At wind speed Â of 15 m/s, an angle of 45Â°, the CL value is 5.51E+04, the CD value is 4.12E+02. At wind speed Â of 15 m/s, an angle of 65Â°, the CL value is 5.96E+01, the CD value is 1.33E+03. Based on this, it can be concluded that at wind speed Â of 5.5 m/s the higher the opening angle, the higher CL produced. At wind speed Â of 15 m/s the larger the opening angle the CD increases. This is because the higher the angle, the more it receives sweeps or catches the wind. While the unstable value generated in this simulation is generally a weakness in the wind turbine design.

Corrosion Under Insulation (CUI) can be described as localized corrosion that forms as a result of the penetration of water or moisture through an insulating material. The pipe material used is of the ASTM A53 standard and the fluid used in seawater because almost all industries are located on the coast. This type of coating is carried out on the test pipe using Meiji Epoxy Filler. The test method is carried out by flowing seawater fluid in pipes with water temperature variations of 30Â°C, 50Â°C, and 70Â°C. This pipe varies the type of insulation by using glasswool and Rockwool (ASTM G 189-07). This insulation is conditioned in a wet state by giving 2 ml of seawater drops with a pH value of 4 per 6 hours. The test equipment is divided into 3 series according to temperature variations with 4 test specimens and 2 coating variations respectively. The test time was carried out for 336 hours to obtain the corrosion rate results using the ASTM G31-72 weight loss method. The results showed that the type of Glasswool insulation with specimens coated had the lowest corrosion rate value of 0.00483 mmpy at a temperature of 30Â°C when compared to the same type of treatment on Rockwool insulation of 0.00724 mmpy or an increase of 2.41 times. This study shows that the type of insulation, temperature variation, and coating greatly affect the rate of corrosion and the type of corrosion that occurs is uniform corrosion.
