Comparative Study on the Comfort of Public Space in Residential Settlement (Case Study: RBRA Kalpataru & RPTRA Anggrek)
Full text linkIn addition to its roles as a water catchment and green space, a city's public space is a location for people to congregate and participate in activities together. For these reasons, public space is a vital component of the design of a city. As study objects, we will be using Child-Friendly Playrooms (RBRA) Kalpataru and Child-Friendly Integrated Public Spaces (RPTRA)Anggrek in our investigation. It is anticipated that the availability of child-friendly public places would facilitate the fulfilment of children's rights, making it possible for them to live, grow, develop, and engage in social activities to the fullest extent possible. The primary topics discussed in this research are the design and requirements of both public spaces in communities with varied environmental and cultural settings. Observation and interviews are the methods that were used in this investigation. This research aims to discover how the general population feels about the comfort level in public spaces. Aspects of thermal comfort, safety, circulation, amenities, noise, and view are evaluated as part of the comfort assessment. RPTRA Anggrek was found to have a comfort level with an average score of 94.5 (very good), which was higher than RBRA Kalpataru, which got an average score of 68 (moderate).Â
Rumah Sakit Ibu dan Anak (Healing Environment)
No full textMother and Children Hospital is a special hospital that provides services to
mother, both maternal and woman on reproductive issue and to children aged
between 0 to 18 years.
Medan Johor is one of the district in Medan with population 123.851 people.
There are 10.265 fertile women, 46.786 children aged 0 to 18 years and 2.040
maternal in this area, while there is only one public hospital. Although there are
several maternity hospitals, but estimated that the maternity hospitals cannot afford
to solve the childbirth issue, especially the abnormal childbirth which should be
referred to the special hospital.
According to the reality, then it feels that we need to build a mother and children
hospital which is proper to be able of giving services for Medan Johor and
surrounding communities.
The site is selected at A.H. Nasution St. because this location is in a strategic
area, which is located in the middle of the settlements.
There are several things that have to be noticed by the hospital provides, one of
them is how to make patients feel comfortable during their stay in hospital, both of
the quality of services as well as the physical circumstance of the hospital (the
beauty and completeness of the building, including the beautiful landscaping,
adequate parking area, the amazing interior design, lift, cafe, souvenir shop, clean
toilets, etc), thus making the patient doesn’t feel in the hospital. For that, the hospital
implemented a Healing Environment in its design theme, which incorporate the
natural elements into the hospital, such as terraced gardens and water elements.156 HalamanSkripsi Sarjan

Heat transfer through building envelope materials and their effect on indoor air temperatures in tropics
Full text linkHigh thermal mass modern building materials are unsuitable to be used in the tropics due to their thermos-physical properties and the ability in absorbing solar radiation, storing and transferring heat into the building, affecting the high indoor air temperature, hence, reducing thermal comfort. However, due to the high demand for building, utilization of this material is avoidable. This study investigated the heat transfer through building envelope materials and their effect on the indoor air temperature of the building through field measurement using a thermal camera and a handle wind meter. The results found that the ceiling is the part of the building which gained the highest indoor surface temperature which reaches 38.6 °C at the apex point at 2pm but decreased significantly to 30.4 °C at 6 pm. Meanwhile, the inner of the northeast wall gained 33.1 °C at the peak temperature and stayed above 30 °C until 10 pm. The indoor air temperature of this unit housing was 36.3 °C at 2 pm with the temperature difference between outdoor and indoor was 2.5 °C. At night, the indoor air temperature was 3.8 °C higher than the outside temperature
Design of Green Hybrid Cementitious Composite for Sustainability Enhancement
Full text linkBuilt environment sustainability is progressively coming to the upfront in the design of infrastructure as well as in the process of decision making for maintenance work. In confronting this, there is a need for the development of innovative green cement-based materials. These materials should be invented based on the needs of the final application in which they will be implemented. The actions of ignoring the connection between the developments of material, design of structures and sustainability objectives which can result to expensive, short life span, and resource-intensive structures that will need a higher cost of maintenance in a short while are becoming obsolete. This study presents the development of a design framework which was used to produce green hybrid cementitious composites for infrastructure implementation. By means of intentional and careful control of composites constituents and the tailoring of the materials similar to engineer cementitious composites, cement-based hybrid cementitious composites were developed and the mechanical properties are presented. Metakaolin, (MK) and nano-silica (nSi) in colloid form, as well as epoxy, were used as partial replacement of cement content at 12%. Fibers, oil palm, coconuts and artificial barchip were used at 2%. The impact of all these hybrid materials was tested at certain ages of 7, 28 and 90 days. The result shows that despite the replacement, the hybrid cementitious composites performed better in terms of mechanical properties than the same control sample without Metakaolin, nano-silica and epoxy
Ventilation Performance of Air Duct in Double Loaded Corridor Building: A Case Study
Full text linkBuildings with double-loaded corridor types are often found in Indonesia and generally function as offices or lecture rooms. This type of building is popular because of its efficient circulation path to accommodate the movement of occupants. However, a wall separating the room from the corridor makes it impossible to put windows to implement a cross-ventilation system due to acoustic problems. Hence, to achieve indoor thermal comfort, this type of building relies on using an air conditioning (AC) system. However, with the WHO's call to reduce the use of AC during the COVID-19 pandemic, it is necessary to evaluate cross-ventilation in double-loaded corridor buildings to meet comfort standards while still preventing acoustic problems due to noise from corridors and other spaces. The study proposes a new natural ventilation system using air ducts placed above the corridor ceiling to create cross-ventilation in lecture buildings. The E-ITERA building was chosen as a case study in this research. The building has a glass facade with several small windows that can be opened outside. The corridor of this building is designed with openings at both ends, allowing for direct connection to the outside air. The walls facing the passage have a single door and four small ventilations on the aisle's upper side. Simulations were carried out in two classrooms on the 3rd floor using CFD (Computational Fluid Dynamics) software. Experiments were carried out to change the size of the air duct and the size of the ventilation on the wall that leads to the corridor. The results showed that the air duct was able to create cross-ventilation. Ventilation performance is improved when the WWR air duct is the same as the WWR window. The highest air velocity in the centre of the room is 0.6 m/s. Doi: 10.28991/CEJ-2023-09-10-06 Full Text: PD
Porous silica nanoparticles as carrier for curcumin delivery
Full text linkMesoporous silica nanoparticles (MSN) with large surface areas and pore volumes show great potential as drug and gene carriers. However, there are still some challenging issues hinders their clinical application. Many types of research in the use of mesoporous silica material for drug and gene delivery involving complex and rigorous procedures. A facile and reproducible procedure to prepare combined drug carrier is required. We investigated the effect of physiochemical parameters of mesoporous silica, including structural symmetry (cubic and hexagonal), particles size (micro size: 1-2 μm and nano size: 100 -300 nm), on the solubility and release profile of curcumin. Transmission Electron Microscopy, XRay Powder Diffraction, and Nitrogen sorption were used to confirm the synthesis of the mesoporous silica materials. Mesoporous silica materials with different mesostructures and size have been synthesized successfully. Curcumin has anti-oxidant, anti-inflammation and antivirus properties which are beneficial to fight various diseases such as diabetic, cancer, allergic, arthritis and Alzheimer. Curcumin has low solubility which minimizes its therapeutic effect. The use of nanoporous material to carry and release the loaded molecules is expected to enhance curcumin solubility. Mesoporous silica materials with a cubic mesostructure had a higher release profile and curcumin solubility, while mesoporous silica materials with a particle size in the range of nano meter (100-300) nm also show better release profile and solubility
