Excavated Earth Area Maximization as a Basement and Outdoor Living Space on a Sloped Terrain Housing
Authors: Pramono A , Yuninda C , Munir B 
Published: May 2023

Abstract
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.

Abstract
Creativity is the rationale possessed by humans in which conscious and unconscious processes occur in problem solving and the creation of a work product. 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.

Abstract
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.

Abstract
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.

Published: May 2023

Abstract
Sorghum has been widely cultivated around the world. The plant has a high survival rate to be grown in barren land and is reported to be positively correlated with health benefits, in particular for being gluten-free. Recently, sorghum application in food products has increased significantly. This study aims to investigate consumer acceptance of sorghum biscuits and to evaluate whether consumer knowledge related to sorghum will influence their preferences. The preferences of 132 adult consumers were recorded for the different substitutions of sorghum to wheat (0%, 25%, 50%, 75%, and 100% of sorghum substitution). Sensory attributes of sweet and bitter aroma, sweetness, bitterness, texture, and grittiness were recorded using the JAR (Just-About-Right) scale while consumer knowledge regarding sorghum and gluten-free product was recorded using an online questionnaire. The result indicated that consumer knowledge did not influence their liking on sorghum biscuits, and they have limited knowledge concerning sorghum and gluten-free products. The liking was significantly influenced by the sensory attributes of biscuits. Texture quality such as hardness and grittiness showed to significantly reduce liking while sweet aroma, sweetness, and soft texture showed to promote liking. This study could be used as a preliminary study to develop gluten-free products using sorghum.

AbstractAmong the indigenous fermented foods, shrimp paste has been traditionally consumed in Southeast Asia as a condiment to its delicacy and nutritional value. In addition, shrimp paste is added to main dishes to enhance the salty and umami taste. Shrimp paste is named differently in Southeast Asia countries and possesses varied processing methods and microbial composition. This paper aimed to review the production process and microbial composition of shrimp paste in various Southeast Asia countries: mam tom in Vietnam, kapi in Cambodia and Thailand, belacan in Malaysia, terasi in Indonesia, ngapi in Myanmar, and bagoong-alamang in Philippines. Generally, the shrimp paste is made by mixing the ground shrimp with salt at the beginning, followed by fermentation and drying process. Interestingly, some shrimp paste is made through multiple fermentation and drying process to obtain desired consistency. Lactic acid bacteria were identified in most of shrimp paste in Southeast Asia.

Abstract
Traditional herbal drink is made from local herbs and is believed to be able to increase immune system. Bandrek is a Javanese traditional drink commonly made with local herbs and spices. One of the important ingredients should be added in bandrek is ginger. The objective of this study is to investigate consumers’ preferences of bandrek with different processing treatments of ginger (control, cold press, oven-cold press, cold press-boiled, smashed-boiled). In addition, sensorial profiles of bandrek with different ginger treatment was also investigated. A total of 105 consumers participated and their liking scores for bandrek were assessed. In addition, the descriptive sensory evaluation was measured using QDA (Quantitative Descriptive Analysis) by 13 trained panelists and the total antioxidant activity was analyzed using DPPH (2,2-diphenyl-1-picrylhydrazyl) method. The result shows that the bandrek drinks with cold pressed ginger had the highest antioxidant activity compared to the other samples. Moreover, these samples were also shown to be closely associated with consumers’ preferences and correlated with the aroma and taste of spices and herbs including the hot sensation of ginger. This study could be used as a preliminary study to develop functional drinks made from ginger by considering ginger treatment and its antioxidant content.

Abstract
This study aimed to screen the lactic acid bacteria (LAB) strain that has high potential in gamma-aminobutyric acid (GABA) production and antibacterial properties, which could be applied in Vietnamese fermented meat (Nem chua) fermentation. These bacterial strains were isolated from commercial Nem chua products and stored in the laboratory. GABA synthesized from 18 strains of LAB in the MRS media adding 3% MSG was qualitative and quantitative analyzed through thin layer chromatography (TLC) and its calibration curve equation, then antibacterial activity and lactic acid production were also tested by acidic titration method, and well diffusion method, respectively. The results showed that all LAB strains synthesized GABA with a concentration from 1.323 - 1.582 mg/mL; however, eight strains were recorded with higher potential, including VL1, XP1, TP1, HC2, CP2, LV2, TX7, and HK 162. These eight strains showed the inhibition zone to Escherichia coli indicator from 4.67 - 11.67 mm. Besides, they are capable of yielding lactic acid from 18.00 - 19.35 g/L after seven days of fermentation in MRS media. The strain VL1 with the highest potential was identified as Lactobacillus plantarum. This strain was suggested as a promising starter to be applied in the Nem chua fermentation process.

Published: May 2023

Abstract
Recent advances in tumor microenvironment (TME) modeling as well as its applications to cancer therapy has brought various dramatical changes in multiple malignancies management. Understanding the mechanisms of response and resistance to cancer therapy requires a clear elucidation of the intricate interactions between TME cells, the surrounding stroma, and distant affected tissues or organs. To address this demand, various three-dimensional (3D) cell culture techniques have been developed in order to recapitulate and understand cancer biology over the past decade. This review summarizes some saliant progresses in in vitro 3D TME modeling, including the cell-based, matrix-based, and vessel-based dynamic 3D modeling techniques and their applications in investigating tumor-stroma interactions and responses to cancer therapies. The review also discusses the limitations of current TME modeling approaches and proposes some new thoughts on the construction of more clinically relevant models.

Published: May 2023

Abstract
The friction stir spot welding (FSSW) process is a novel technique that overcomes the limitation of resistance spot welding. Recently, FSSW used for welding of polymers which are difficult to be joined by traditional welding processes. The demand for Acrylonitrile Butadiene Styrene (ABS) for industrial applications has increased in recent years. However, to employ this technique the challenge is to get optimal FSSW parameters setting to achieve the best weld strength during the welding of ABS sheets. To achieve this, in the present work, full factorial experimental design layout was employed to investigate the effect of process parameters on weld strength i.e., ultimate tensile strength (UTS) and percentage elongation during FSSW of ABS-ABS sheet in butt configuration. To predict the UTS and percentage elongation, machine learning regression namely, linear, polynomial, support vector machine, and decision tree was used. Further, the study includes the identification of the fracture patterns post tensile test specimens based on the topography of the fracture surface under scanning electron microscopy. It was found that plunge depth is the most significant parameter followed by spindle speed and dwell time. The optimal setting of process parameters i.e., spindle speed of 1000 rpm, plunge depth of 1 mm, and dwell time of 40 s resulted in maximum UTS of 7.849 MPa. The maximum value of percentage elongation obtained was 5 at the parameter setting of spindle speed of 1000 rpm, plunge depth of 0.8 mm, and dwell time of 40 s. Polynomial regression outperformed in the prediction of UTS and percentage elongation with an R-square of 0.99.

Abstract
This article describes experimental research studies conducted toward understanding the implementation aspects of high-capacity quantum-secured optical channels in mission-critical metro-scale operational environments using quantum key distribution (QKD) technology. To the best of our knowledge, this is the first time that an 800 Gbps quantum-secured optical channel—along with several other dense wavelength division multiplexed channels on the C-band and multiplexed with the QKD channel on the O-band-was established at distances up to 100 km, with secret key-rates relevant for practical industry use cases. In addition, during the course of these trials, transporting a blockchain application over this established channel was utilized as a demonstration of securing a financial transaction in transit over a quantum-secured optical channel. The findings of this research pave the way toward the deployment of QKD-secured optical channels in high-capacity, metro-scale, mission-critical operational environments, such as Inter-Data Center Interconnects.
