The Field application efficiency Assessment of Paddy Field in Aceh Irrigation Scheme, Aceh, Indonesia
Authors: Rizalihadi Maimun , Abdullah  , Nizarli  , Safwan
Published: May 2023

The efficiency of project irrigation is the main factor in measuring the irrigation system’s effectiveness in conveying and distributing the water to a paddy field. The efficiency of irrigation projects in Aceh adopted from Indonesian irrigation standards is 65% which is much higher than generally used in some countries in Asia, i.e., 35-46%. This high value is caused by neglecting water losses in the paddy field when determining the project’s irrigation efficiency. This results in insufficient water for the overall irrigable areas planned in the irrigation scheme in Aceh. The study is aimed to assess the field application efficiency by investigating the water losses in paddy fields. To conduct the research, the paddy field in Pandrah Irrigation Project is plotted specifically. A drum technique instrument was installed in the plot to measure the evapotranspiration, percolation, and effective rainfall based on water balance analysis in the drum in one paddy growing season. The results showed that the field application efficiency is 75.34%. meaning some of the water supply could not be effectively consumed by the paddy. Based on the investigation, most water losses in paddy fields are caused by preferential flow through macropores in vicinity bunds which were triggered by the movement of rats, paddy roots, and bad plow of the field. Therefore, it is recommended to investigate the water losses that will occur due to the above assumption by continuing research in the future, so the project efficiency might be stated accurately when planning irrigation projects in Aceh.

Published: May 2023

The development of a city that including infrastructure support has a massive impact on environmental conditions and climate change. Green buildings are the key solution to environmental problems. However, the implementation of the green buildings are very slow in Indonesia. Most of dominant inhibiting factors for green building implementation are the difficulty of obtaining green materials, a lack of understanding of the importance of green buildings, the additional costs required to build green buildings, and the lack of support from the government. This research is conducted to sort out the factors inhibiting the construction/implementation of green buildings from the angle of contractors and owners. Many questionnaires have been distributed in cities in Indonesia then found that the factors that hindered contractors were lack of research on green building, lack of demand from owners, lack of strict regulation from the government, failures in planning, and longer project duration. From the owner’s side, what is anchoring is the lack of attention and interest, limited research on green building technology, high costs, and lack of cooperation between parties that support the owner delivering a green building.
Analysis of sheet pile position influence in countermeasure to landslide at the cutting slope in infrastructure project
Authors: Tantrio Anderson , Suhendra Andryan
Published: May 2023

Slope is a land surface that has a certain angle of inclination in the horizontal plane. The existence of the slope of the land causes the forces that push so that the soil at a higher elevation to move. If the movement is not resisted, the slope may collapse. The purpose of this analysis is to determine the effect of sheet piles where the position and depth of sheet piles, ground water level and earthquake factors on the stability of excavation slopes in infrastructure project of Karawang New Industry City (KNIC) LG area. For this reason, slope stability analysis was carried out using a finite element-based analysis program where the output sought was sheet pile displacement and safety factor. The data used in this study are N-SPT data and W-325 sheet pile property data. The sheet pile position is varied into 6 variations, at positions 2, 4, 6, 8, 10, and 12. The sheet pile length is varied from 4 meters to 12 meters and the slope water level is varied into 6 conditions, namely conditions without ground water, ground water level 5 meters, 4 meters, 3 meters, 2 meters and 1 meter. From this analysis it was found that the position of sheet pile affects the value of the safety factor and the critical depth of sheet piles. The analysis is continued by analyzing the earthquake load at a water level of 1 meter. From this analysis, all positions and depths are not able to withstand earthquake loads, so other alternatives are needed. Considering the earthquake load and the resulting landslide pattern, the slopes require additional reinforcement where sheet piles will be installed in position 10 with a length of 12 meters and at 1 meter from the roadside at a depth of 1 meter with a length of 11 meters. With this reinforcement, the safety factor value is 1.675 in static conditions and 1.131 in earthquake conditions so that sheet piles can meet the minimum limit requirements i.e., 1.5 in static conditions and 1.0 in earthquake conditions.
Corner Effects of Retaining Wall on Lateral Stress Distribution and Deformation
Authors: Kosalim Valdy , Gunawan Anthony
Published: May 2023

Retaining wall is commonly analysed in two-dimension (2D). This assumes that the wall is in plane strain conditions. While for most cases this assumption is applicable, the same cannot be applied to corners of retaining wall. This study aims to study the corner effects of retaining wall by modelling it in three-dimensional finite element software, PLAXIS 3D. The meeting point of two retaining wall is varied from 45° to 315° at 45° interval. Another parameter studied is the wall height, which is varied from 3 m to 9 m in 2 m intervals. The analysis shows that 45° and 90° walls have the lowest earth pressure and wall displacement. This is due to arching effects which is not present for walls with meeting point 135° and larger. As for displacement, the largest displacement is from 180° wall. This is because the movement of 180° wall is not restrained by the boundary conditions. For walls of other geometries, boundary conditions of the finite element model restrict the movement of walls in horizontal and/or vertical directions. Other factors include larger base geometries for non-180° wall, as well as distribution of disturbing force and resisting force.

Flooding is the inability of the channel capacity to accept stormwater so that it overflows into the surrounding area. The main problem of flooding in Jakarta is not in the main channel but in micro drainage which is commonly known as pluvial flooding. This research was conducted to increase resilience (reduce the risk of flooding) by making a device that is able to handle floods that can reduce the height and time of flooding in a location where flooding occurs. Floods cause damage. The parameters that are very important in determining the damage are inundation height and inundation duration. The methodology used in this research is to combine early warning system and emergency response based on hydrology engineering, hydraulics engineering and data science. The approach taken is to use an emergency response using the help of an early warning system. The emergency response used in this study is based on a mobile pump and its equipment and power that can be moved at any time. The emergency response is to use an early warning by predicting the microphysical symptoms of clouds that occur in the atmosphere. Emergency response is needed to cooperate together with early warning system in pluvial flooding problem. Unifying early warning system and emergency response system that this research called flood device is able to reduce the depth and duration of inundation.

Visibility is an important element in commercial spaces. However, the importance of visibility in traditional markets–especially in Indonesia–are often overlooked during the design process. One of the markets with this problem is Palmerah Market in Central Jakarta. Palmerah Market is an intriguing topic for architecture research since Palmerah Market has three different functions in one building, such as traditional market, modern supermarket, and auto parts center. Yet, the elements that are supposed to be Palmerah Market’s potential is not operating the way it’s supposed to. This is a result of low visibility and low permeability to each of the market’s zones. This research uses a qualitative method. The data will be analyzed using space syntax theory specifically Visibility Graph Analysis (VGA), that will be simulated through depthmapX software. Visibility Graph Analysis is one of the innovative methods to resolve architectural problems such as visibility. Since visibility can be relative from person to person, it is important to have an indisputable instrument to prove the best visibility value. Visibility Graph Analysis can greatly help on the matter of visibility in the design stage. As a result, this instrument can improve future architectural designs innovatively and have a positive impact on the environmental aspect surrounding the design. The research output will be completed as a design concept of Palmerah Market that solves the design issues related to visibility, accessibility, as well as function. The simulation result has shown that there are several areas in the proposed floor plans that has high visibility points, and thus can be optimized as the main commerce area. Whereas areas with low visibility can be operated for the supporting facilites, such as service area.

Authors: Pramono A , Yuninda C , Munir B
Published: May 2023

The cut-and-fill technique frequently creates a space for housing on sloped terrain. Some developers use the contours of the land on sloped terrain for garden areas instead of developing it into space to reduce production costs when building houses. By developing structures for building reinforcement, this research seeks to use the excavated earth area in the sloped terrain as storage space and outdoor living space. A single case study in a Malang City home situated on a sloping terrain served as the research approach. Primary data were collected through field surveys and customer interviews to determine the design of the room based on space requirements. Secondary data for this study also comes from a literature review. The first step for the architect is to plan the room’s layout following the client’s requirements. The next stage is to choose the foundation for the project by taking the soil’s structure and condition. The final stage is also decided upon the outdoor living space’s finishing material and the furniture for the outdoor room. The final result indicates that the excavated earth area is beneficial as a storage place at the bottom and an outdoor living area at the top. Outdoor living spaces are beneficial because they provide extra space and address home design issues by reducing the spread of airborne viruses like Covid-19. Maximizing excavated earth as a warehouse space and functioning as an outdoor living space is one of the applications of sustainable design in architecture.

Creativity in the process of creating each individual, especially in the field of design education, can be trained by giving stimuli based on the problems obtained in the surrounding environment. This research considers the ecosystem problem through the environment, especially industrial waste with rattan material, which accounts for almost 10% of waste from raw materials used every month. The waste treatment becomes a medium for sharpening student creativity. The study was conducted by conducting a project design that processes waste problems into new, more commercial products to see the creative process. Research involves lecturers and experts from the design industry related to the process and achievement of creativity based on thinking patterns in solving a problem. Various results were found where the achievement of creativity through the process was successful and some failed. This design project-based training is a challenge for lecturers to be able to improve their role performance and direct students as young designers to sharpen their creative abilities.

A novel putative D-allulose 3-epimerase (DAEase) named CcDAE with the accession number of WP_183335203.1 was discovered in this study from Chelatococcus composti genome using in silico genome mining method. The sequence, which was retrieved from the genome of Chelatococcus composti strain CGMCC 1.15283 and became the first reported D-allulose 3-epimerase from the species. The sequence length of CcDAE was 282 aa with a molecular weight prediction of 30.504 kDa. The sequence analysis disclosed a high sequence conservation at the residues building the metal binding site and substrate binding site. The phylogenetic tree also disclosed that the closest related sequence with CcDAE was from Cereibacter spaeroides. The biochemical prediction also informed that CcDAE had an isoelectric point (pI) at pH 5.74. In addition, the novel putative enzyme was predicted to withstand a high temperature up to 65 °C and was considered as a stable protein. Therefore, the research finding suggests that CcDAE was potential for further exploration.

The immense food demand in Indonesia can no longer be satisfied by the current agricultural and plantation process. Both sectors need a more effective and productive solution to produce more food while also maintaining the quality. Yet, most of the farmers work in remote and rural areas where technology is an uncommon thing. Indonesia’s agricultural and plantation sectors are urgently in need of technological support to upgrade the processes, specifically for lower-to-middle class farmers. Emerging technologies such as the Internet of Things (IoT), Artificial Intelligent (AI), and Machine Learning (ML) need to be adopted to system dynamics in agricultural processing, specifically drying stage. The drying model system that adopts the greenhouse concept, such as the solar dryer dome, is one of the promising drying methods. Implementation of industry 4.0 technology can optimize the solar dryer dome through several activities such as IoT that can track and organize the dryer data remotely or ML/AI that can automatically predict and control the dryer environment. This is proven by our developed smart solar dryer functionality and capability to support the agricultural drying process by utilizing IoT-enabled connection and AI/ML system. In this study, researchers review the development of solar dryer in Indonesia and provide the results from the developed smart solar dryer to optimize and encourage the development Indonesia’s agricultural industry which potentially improve post-harvest product quantity and quality.

People are starting to implement a healthy lifestyle with a vegetarian consumption pattern. The study aimed to determine the importance level between attributes and the utility values of each level to design plant-based meatballs. Furthermore, we compared the sensory acceptances of prototypes product and commercial plant-based meatballs. The study consisted of three stages, which were a preliminary survey (n=51), a conjoint survey (n=163), and an organoleptic test (n=40). The surveys were conducted through online questionnaires. The characteristics of respondents were between the age of 17 to 45 years old. Besides, the respondents had experience consuming meatballs and plant-based food. The preliminary survey resulted in the attributes and level for conjoint questions. The conjoint analysis showed that the attribute importance values from the highest to lowest were elasticity, dominant taste, the information of nutritional value, price, ingredients information, and smoothness. Based on the utility score, the consumer preferred meatballs with a dominant umami taste and a springy and smooth texture. Besides, the label contains complete ingredients composition and nutritional information with the price of IDR 35,000 (USD 2.33) for 25 meatballs. The organoleptic acceptance of the prototype meatball product was not significantly different from the two samples of commercial vegetarian meatballs.
