Abstract
As an effort to optimize the use of smart farming technology aimed at increasing efficiency in agriculture, a study was carried out at Agro-Innovation Park (Tagrinov), a place for education and learning of innovative home yard utilization concept. The smart farming applied in Tagrinov were irrigation control systems, pH and nutrition control systems of hydroponic plant, and temperature and humidity control in aeroponic systems. Those three monitoring and controlling systems were integrated in the mobile apps called Tagrinov 4.0. The deployment of control mechanism involved some systems, namely communication testing of android application using firebase server for irrigation; the Arduino Mega 2560 for pH level and nutrition control of hydroponic plant, and the Arduino Uno, DHT22 and DS18B20 sensors for temperature and humidity control of the aeroponic system. The test results showed some advantages of smart farming application in Tagrinov. Irrigation control system using internet network can be easily carried out by users. Arduino makes the system automatic, the pH sensor works as pH meter, the nutrients turn on and off when the pH value and nutrients are appropriate. The aeroponic sensor system read the temperature and humidity in the parent seed nursery, to activate the sprayer and makes the water become mist. All smart farming technologies were operated through mobile apps making these systems more efficient.

Abstract
Residual liming is one of the measures of the efficacy of liming materials. Ca2+-amendments such as calcium hydroxide (Ca(OH)2), calcium oxide (CaO) and calcium carbonate (CaCO3) in soils may contribute to plant growth response in plant height and total dry matter yield of oil palm seedlings. The increasing of other essential elements such as nitrogen (N), phosphorus (P) and ions of potassium (K+) also play a great role in the plant growth and crop yield, conversely, the soil pH and ions of aluminium (Al3+) will inhibit the plant growth and crop yield. This main aim this experiment is to determine the residual liming effect of Ca2+-amendments to highly acidic soils collected from Jeram and Bungor series, Malaysia, which also contains 2 times of Al3+. The highly acidic soils of previously planted with oil palm seedlings initially incubated with selected Ca2+-amendments along with Mg2+-amendments such as, dolomite (CaMg.CO3) for 360 days and, kept for additional 180 days before planting for a total of 540 days in a greenhouse environment. In this experiment, the soil chemical analysis, plant growth response, and the possible mechanisms responsible for the Ca2+-amendment liming effects were measured. The results of the soil chemical analysis showed that Ca2+-amendment residues potentially reduced the soil acidity than Mg2+-amendments. Ca(OH)2 was the most prominent Ca2+-amendment to increase soil-water pH, soil solution pH, and concentrations of soluble Ca2+ and K+. While, concentration of soil solution and exchangeable Al were effectively reduced 540 days after the application of Ca-amendments. The dry shoot weight of the oil palm seedlings improved about 1.67 g/pot and 16.87 g/pot in control and Ca2+-amendment treatments, respectively. In this study, it has showed that the root dry weight of oil palm seedlings increased from 0.18 g/pot to 4.49 g/pot in pot and Ca2+-amended soil, respectively. Increased plant height and total dry matter yield of oil palm seedlings grown on the Ca-amended soils may be attributed to increased soil pH which resulted in lowered concentration and activity of soluble AI, and increased concentrations of soil solution Ca and K which were released of Ca. This finding concluded that the possible mechanisms of Ca2+-amendments from residual liming might be: a) complexation interaction between Al3+ and Ca2+; (b) capacity of Ca-amendments to increase the concentration of Ca to maintain soil desired pH; (c) alleviation effect of Ca-amendments to reduce Al toxicity concentration in the soil. Last but not least, this finding showed that dry matter yield and plant height positively associated with the presence of Al3
+ in both soil conditions.

Abstract
This study was conducted to develop an ethanolic solid dispersion of Orthosiphon stamineus (ESD) using polymers as carriers, namely polyvinylpyrrolidone (PVP), poloxamer 188 (P188), and poloxamer 407 (P407) via the solvent evaporation method. The purpose of preparing the formulation is to improve the solubility of the lipophilic flavones, namely sinensetin (SIN), eupatorine (EUP), and 3′-hydroxy-5, 6, 7, 4′-tetramethoxyflavone (TMF) and caffeic acid derivatives, namely rosmarinic acid (RA). The optimized ESD was characterized using High-Performance Liquid Chromatography (HPLC), Attenuated Total Reflection Fourier Transform Infrared (ATR-FTIR) fingerprints, and physicochemical methods (particle size, zeta potential, TEM, and SEM). The effect of pH on stability and solubility in buffer and water, in-vitro release, and antioxidant properties (DPPH assay) indicated that the nano-formulation ESD using polymers (PVP/P407) with a ratio of extract to polymers (1.0:1.1:0.3 w/w) enhanced the lipophilic flavones (TMF=3.56 ± 0.01% w/w, SIN=2.46 ± 0.01% w/w and EUP=7.87 ± 0.01% w/w) and RA (20.66 ± 0.01% w/w) compared to the same compounds in ethanolic extract (P< 0.0001) with particles size less than 200 nm. In conclusion, the successful development of ESD using water-soluble copolymers (PVP/P407) has enhanced the solubility of lipophilic flavones and other compounds (RA), thereby further improving its pharmacological properties.

Published: May 2021

Abstract
Our study aims at evaluating the daylight model as a design approach, facilitating the architect to improve spatial quality, and making sense of spatial sensation of a daylight model through a quantitative method of sequential and time-based image analysis. We investigated two spatial criteria affected by light, namely calming and exciting [10], defined by four light indicators: contrast, intensity, uniformity, and colours. The mechanism of the experiment was performed on the process of a conceptual design of a museum of modern art in Bandung, where design decisions of architectural layout and element, space, and form were defined and determined based on the result of analysis over series of rendering images instead of conventional diagram-to-plan approach. In this method, each image contains measures of the predictive perceptual effect of daylight for the decision-making process. On the notes of this study, the quantitative and formal approach through image-based analysis has its benefit to model the intangible aspect of architectural design and potent to improve objective measures of spatial quality.

Authors: Larasati Widya Laksmi , Kurniawan Kemas Ridwan 
Published: May 2021

Abstract
Hermeneutic is a science of understanding a focal point of a cultural system; which in the field of history is known as the spirit of the people. The spirit transforms into objects – such as art-displaying the object maker’s thoughts or state of mind. This research began as an attempt to apply hermeneutic onto historical architecture object; on the understanding that architecture is an example of the production of art. The chosen object was the Amsterdam Gate of Batavia (Dutch: de Amsterdamse Poort te Batavia) built in mid-18th century in VOC-era Jakarta. The gate underwent several transformations before it was demolished in the 1950s, yet records of its existence; including photographs, lithographs, and journals are still widely accessible today. The historical events including those directly related to the transformations as well as general situations of the town and the ruling government are analysed. The research revealed a probable relation between the physical condition of the architecture and the socio-political situation of the nation, written in simple phrases to assist readers in envisioning the state of mind behind the concretized built environment.

Authors: Syahriyah Dewi R 
Published: May 2021

Abstract
Residential buildings consume a lot of energy and can cause environmental damage, especially in the post-occupation and operating phase. In order to minimize environmental damage, the green building concept was chosen as a solution that can minimize the causes of environmental damage. Pro-environmental behavior of residents is suspected to be influenced by the occupants environment, which is the physical characteristics that exist in the vertical housing. This study aims to analyze the correlation of physical characteristic in a residential building with the value of pro-environmental behavior, especially on student vertical housing. Based on purposive sampling (non-random/non-probability sampling), correlation analysis shows that the physical characteristic has a high correlation with a significant value of < 0.05 towards pro-environmental behavior. The physical characteristics of vertical housing define into three categories, which are site characteristics, building characteristics, and residential unit characteristics. On site characteristics, the highest significant value is at site accessibility, building density, and vegetation distribution. In building characteristics, the highest significance value is in building blocks, distribution systems, building floor area, and the number of residential units. While the characteristics of the residential unit, the highest significance value is found in the occupancy unit area and the existence of the bathroom.

Abstract
Special Region of Yogyakarta is passed by the ring of fire and become a province which prone to disasters, especially earthquake. In 2006, Wonolelo Village was one of the villages hardest hit by the earthquake. Therefore, understanding and awareness of disaster management are important. Currently, disaster management at local is widely applied. According to Van Niekerk, et al (2017), the approach at the local level aims to change the perspective of disaster management in terms of issues, challenges and problems faced by the community. For this reason, Wonolelo Village has a disaster-aware community, the Disaster Risk Reduction Forum (FPRB). The purposes of this research are to identify the processes and factors that influence the success of sustainable CBDM in Wonolelo Village. The method used is qualitative. Based on the analysis, Wonolelo Village has three stages of the disaster management process, namely the identification, the planning and implementation stage, and the development stage. While the factors that influence the success of disaster management in Wonolelo Village are the choice of Wonolelo Village as a Pilot Project by NDMA, recurring disaster events, volunteers who have team awareness, the existence of cooperation culture in the community, and budget allocation from Wonolelo Government for CBDM.

Published: May 2021

Abstract
The increasing number of disasters and high costs of damage highlight that financing is an essential part of managing community disaster response. As the most significant spending related to a disaster occurs after the disaster strikes, it can be challenging to know how much this spending could be reduced through preparedness in disaster management. This paper discusses the budget allocation of ex-ante programs on disaster risk reduction, focusing on education, knowledge awareness, capacity building, and risk communication. Special attention is paid to budget management programs in the Merapi Volcano area. A literature review is carried out to create a profile of the budget allocation for awareness programs in the whole disaster management cycle. It is found that the budget allocation for such programs is 7% of the total budget of the rehabilitation and reconstruction project and 20%–30% of the annual budget of the Local Disaster Management Agency. The findings demonstrate a need for alternative budgeting for ex-ante programs on disaster risk reduction to accelerate the targeted outcomes.

Published: May 2021

Abstract
Contoured land condition in mountainous area with a slope requires a cost consuming to make it a suitable land to function as commercial lands, such as a villa complex property. It is still a great choice for this business since it does not only have attractive natural views but also fresh air quality, making it comfortable to stay. The problem is how is the recommendation of land use design for villa complexes in mountainous areas with contoured land to increase profits. There are three stages in conducting land use design, first is the identification stage regarding the existing data analysis including accessibility and land slope through contour lines. Second, the process of concept formation, which becomes an analysis to determine the circulation and basis counting of villa land unit lots. Third is the evaluation stage, which is a stage of checking the land use precedent as validation in similar issue to prove the profit rate. The results will serve as a guide for investors and architects in determining the land use configuration on contoured land to optimize construction costs and increase profits as well as contribute to the development of land use knowledge on an urban-scale.

Abstract
Electronic atlas (e-atlas) of health is a multimedia website system, containing a compilation of health and disease maps. Selangor is one of the states with a high rate of physical development and having major disease burdens. Empowering local communities on wellbeing education through a digital network is one of the effective ways to reduce the incidence of diseases and health issues. This paper aimed to design and develop an e-atlas of health according to the local user requirement. A collection of hardcopy health maps from student’s Cartography projects, Adobe Illustrator and ArcGIS Online were utilized to create the system according to the waterfall model. The finding of the user requirement has indicated the existing websites has general information on health but the e-atlas elements of health are not fully established-particularly in Selangor. Thus, this proposed interactive mapping system has demonstrated several sub-menus regarding the health aspects such as waterborne diseases, vector-borne disease, health care facilities, and others. General info on the Selangor wellbeing features with good cartographic elements have been also incorporated. Eighty-five per cent of respondents gave the positives feedback, but they are hoping that this community services system could be applied practically in the future.

Abstract
Presently, the Global Navigation Satellite System (GNSS) technology provides numerous positioning services for engineering and scientific applications with regional to global coverage. The Quasi-Zenith Satellite System (QZSS) is one of the GNSS technologies owned by the Japanese government, which orbits around East Asia, Asia Pacific, and Oceania. One of the advantages of the QZSS satellite is that it corrects measurements using precise ephemeris, clock, and other augmenting corrections, primarily used for the Real-Time Precise Point Positioning (RTPPP) method. Indonesia is a country that is included in the orbital area of the QZSS system. This study aims to see the QZSS system’s performance for RTPPP measurements in Indonesia’s land area. Magellan System Japan’s (MSJ) receiver is used in this study to collect the GNSS as well as the augmenting data and perform the RTPPP. RTPPP method is then made into three different schemes. The first scheme measures the RTPPP at a point to see the precision level. The second scheme takes measurements simultaneously with DGPS-Veripos measurements. Lastly, the third scheme measures using the RTPPP using both QZSS’s augmentation and ATLAS correction system, Static, and Real-Time Kinematic (RTK) on 20 benchmarks. The resulting coordinates for each scheme are then used to evaluate the performance of QZSS augmentation. The first scheme results show the precision level of the QZSS-RTPPP 5 cm and 10 cm for the horizontal and vertical components, respectively. In scheme two, the precision of the estimated coordinates from the DGPS-Veripos is better than those from the MSJ receiver in both horizontal and vertical components. Using the static method results as a reference, the accuracy of the RTPPP using the QZSS augmentation is 0.110 m, 0.056 m, and 0.120 m for easting, northing, and height component, respectively. Based on these results, some improvements are still needed to improve the QZSS-RTPPP method’s accuracy in Indonesia.

Nowadays, the road network documentation is required for many applications, it is essential for the development of economy and its growth brings benefits in people’s life. Traditionally, the road network extraction is done manually, however, it is costly, and time consuming to update and utilize the spatial information. Thus, in order to utilize this issue, this study aims to evaluate the capabilities of automatic road extraction from orthophoto UAV images using Trainable Weka Segmentation (TWS), Level Set (LS) and Seeded Region Growing (SRG) methods. The study area was carried out at UiTM Perlis Branch area. In this study, The UAV image was processed by using Agisoft PhotoScan software to produce orthophoto image, then the road network in the orthophoto was segmented and extracted by using ImageJ Fiji. Several ground controls were also established at the surrounding of study area. For validation purposes, the automatic extracted road network was compared against manual extracted road network. Based on the findings, it was found that SRG method is slightly better in extracting road features compared to LS method in term of completeness, correctness, and quality for automated extraction. It is hope, this study can be used to help reducing the cost and time consumed in extracting features, especially road network, by using automatic extraction instead of manual extraction.

Abstract
Hydrography with respect to the various non-navigation purposes comprises the depictions of maritime features. For a progressively secure route and different applications, the emergence of sonar and swath echosounders currently enables more complete and a detailed description. It is absolutely difficult to find any features at any point in depth in such a way that the IHO has indicated the negligible size for the features to be found and estimated in a region. These activities and exercises are called detecting seafloor characteristics. For the purpose of distinguishing and recognizing, the features characteristic detection may also be utilized which are important to other navigators, for example, wellheads and mine-like attributes. The latter might not have been of navigational significance yet but are, nevertheless, of centrality to those concerned. In the event that the unwavering quality of multibeam on object identification study could be demonstrated or possibly its blunder could be found and has determined it’s constant. The multibeam could be broadly utilized for future ventures. By directing this examination study, the MBES data would be able to be evaluated and the capability extents of this data could be assessed. Thus, this study is aimed to analyse the accuracy of underwater object detection between bathymetry map and backscattered image derived from MBES data. The obtained results have shown that object detection from bathymetry maps have slightly better visualization grade than backscatter images with a near perfection grade of 4.8.
