Published: August 2021

Significance

Daily share of news consumption on YouTube, a social media platform with more than 2 billion monthly users, has increased in the last few years. Constructing a large dataset of users’ trajectories across the full political spectrum during 2016–2019, we identify several distinct communities of news consumers, including “far-right” and “anti-woke.” Far right is small and not increasing in size over the observation period, while anti-woke is growing, and both grow in consumption per user. We find little evidence that the YouTube recommendation algorithm is driving attention to this content. Our results indicate that trends in video-based political news consumption are determined by a complicated combination of user preferences, platform features, and the supply-and-demand dynamics of the broader web.
Psychological resilience predicting cardiometabolic conditions in adulthood in the Midlife in the United States Study

Published: August 2021

Significance

Experiencing early life adversity may negatively impact mental health; however, many of these individuals display psychological resilience or positive psychological health despite experiences of early adversity. This positive capacity for mental health may extend to physical health benefits, including lower cardiometabolic disease. While research suggests that early adversity increases later disease risk, we found that individuals who display psychological resilience to early adversity did not have higher odds of developing cardiometabolic disease. Indeed, those who showed psychological resilience had similar odds of disease to peers who did not experience early adversity. These findings were also reflected in measures of biological cardiometabolic risk. Overall, findings suggest that individuals who manifest psychological resilience may have lower cardiometabolic disease risk later in life.

Published: August 2021

Significance

Many amphipathic lipids, including cannabinoids, lysophospholipids, prostanoids, and leukotrienes, bind to G protein–coupled receptors (GPCRs) through the lipid bilayer. How these lipid ligands get anchored to their receptors and enter ligand-binding pockets is largely elusive. Our results revealed a distinctive lipid recognition mechanism for the prostaglandin D2(PGD2) receptor CRTH2 that is not shared by other prostanoid receptors. Based on the structural analysis, we propose two representative binding modes of lipids in GPCRs. We also identified critical structural motifs and conformational changes of CRTH2 for capturing lipids from the lipidic environment and lipid transition to the binding pocket, thereby offering unprecedented molecular insight into the dynamic lipid-binding processes for GPCRs.

Significance

Self-assembly is one of the central themes in biologically controlled synthesis, and it also plays a pivotal role in fabricating a variety of advanced engineering materials. In particular, evaporation-induced self-assembly of colloidal particles enables versatile fabrication of highly ordered two- or three-dimensional nanostructures for optical, sensing, catalytic, and other applications. While it is well known that this process results in the formation of the face-centered cubic (fcc) lattice with the close-packed {111} plane parallel to the substrate, the crystallographic texture development of colloidal crystals is less understood. In this study, we show that the preferred <110> growth in the fcc colloidal crystals synthesized through evaporation-induced assembly is achieved through a gradual crystallographic rotation facilitated by mechanical stress-induced geometrically necessary dislocations.
On evolution, change, and beyond
Authors: Longa Víctor M.
Published: August 2021

This paper discusses Hubert Haider’s target-article “Grammar change: A case of Darwinian cognitive evolution”. I show why such an article is fascinating (and unconventional), although I will mainly concentrate on several disagreements with Haider and will suggest alternative views to those contended by this scholar. My discussion will highlight five main issues: (1) Haider assumes a purely Neo-Darwinian (i.e. genocentric) view of evolution and inheritance, lacking a more pluralistic approach; (2) Haider rejects the idea of language as a biological phenomenon, while at the same time he seems to assume several characteristics related to a biologically seated trait; (3) as opposed to Haider’s suggestion, the computational system does not need to be language-specific; (4) Haider’s divide between the procedural and declarative components of grammar is perhaps too strict regarding (grammatical) change; and (5) Haider considers that there is no scientific way of deciding the question of language origins and evolution and that complex grammars are too recent. However, I show that a language-like computational power (and perhaps complex grammars) already existed many thousands of years ago.
Darwinian language evolution
Authors: Weiß Helmut
Published: August 2021

Haider’s target paper presents a fresh and inspiring look at the nature of grammar change. The overall impression
of his approach is very convincing, especially his insistence on the point that language was not selected for communication –
hence it is no adaptation to communicative use. Nevertheless, I think three topics are in need of further discussion and
elaboration. First, I will discuss the question whether Haider’s conception of Darwinian selection covers all aspects of grammar
change. Second, I will consider the question of whether an approach that dispenses with UG (as Haider’s does) can explain why
grammars are the way they are. Third, I will question Haider’s equation of grammar with the genotype and of speech with the
phenotype and develop an alternative and more appropriate proposal where, among others, speech corresponds to behavior.
Parental lip-smacks during infant mealtimes
Authors: Wiggins Sally , Keevallik Leelo
Published: August 2021

The lip-smack is a communicative sound object that has received very little research attention, with most work
examining their occurrence in nonhuman primate interaction. The current paper aims to dissect the social potential of lip-smacks
in human interaction. The analysis examines a corpus of 391 lip-smack particles produced by English-speaking parents while feeding
their infants. A multimodal interaction analysis details the main features: (1) rhythmical production in a series, (2)
facial-embodied aspects, and (3) temporal organisation. Lip-smacks occurred in prosodically grouped chains of mostly 3 or 5
particles, with accompanying facial expressions, and were co-ordinated with the infants’ chewing. They highlight the mechanics of
chewing while framing eating as a pleasant interactional event.

The paper contributes not only to the distinctly social functions of a sound object hitherto ignored in
linguistics but also to research on interactional exchanges in early childhood and their potential connection to the sociality of
nonhuman primates.
Pre- and postnominal onymic genitives in (Early) New High German
Authors: Ackermann Tanja
Published: August 2021

This empirical study focuses on the diachrony of adnominal genitives of proper names in (Early) New High German (17th to 19th centuries), e.g.,Carls Hausvs.das Haus Carls‘Carl’s house’. Starting from the observation that word order variation exists within the whole period investigated, the study identifies determining factors for this variation and weights them in a multifactorial model of word order variation and change, the first time this has been done for German. The focus is on formal factors such as syntactic complexity, a factor that increases in importance over the observed time span. The historical data allow not only the investigation of established formal parameters but also the identification of new factors such as the type of inflectional marker (due to genitive allomorphy in older stages of German). In addition to these formal factors, genitive semantics, pragmatic information status and genre are also taken into account. Explanations for the trend towards the postnominal position of complex adnominal genitives as well as the stability of bare name possessors in the prenominal position are discussed.

Authors: Arndt Tabea , Holzapfel Bernhard , Noe Mathias , Nast Rainer , Hornung Frank , Kläser Marion , Kudymow Andrej
Published: August 2021

A scalable concept to prepare high current density windings with high-temperature superconducting material is introduced. The concept covers miniaturized high-current windings and large coils for applications in energy technology as well. The principle is based on a circular disk-up-down-assembly (‘DUDA’) and extended to rectangular coils. First measurements on the assemblies (≈40 turns) in liquid nitrogen are presented as a proof-of-concept. Centre fields of ≈40 mT and ≈340 mT are measured during steady operation and pulsed operation respectively. Operating the assemblies at lower temperatures will strongly increase the current and field performance. Lowering the contact resistance might lead to further improvements. Due to the homogenous structure in the radial direction, shear stresses are minimized and large winding heights can be realized in principle. The DUDA concept of coil windings can be used to build even more sophisticated magnetic arrangements, e.g. Halbach-arrays, or complex windings for new stator configurations of rotating machines. The optional miniaturization offers compact and powerful magnets, e.g. for accelerators too.
Temperature emergence at decision-relevant scales
Authors: Harrington Luke J
Published: August 2021

Signal-to-noise (S/N) ratios are a useful method to assess the significance of future climate change relative to past experiences. Most assessments of climate change emergence have focused on S/N ratios of annual mean temperatures. However, averaging the daily experiences of weather across space or time removes the climate variability actually felt by individuals, and thus presents a less informative view of the speed of current climate change. For example, S/N ratios of annual-mean temperatures experienced by the global population after only 1 °C of warming are larger than emergent changes in daily temperatures after 3 °C of warming, and generally four times more significant when comparing the same warming threshold. Here, I examine the emergence of S/N ratios in temperature at decision-relevant scales, with a focus on daily temperatures where people live. I find that 2 °C of global warming will lead to between 30% and >90% of the global population experiencing the emergence of unusual daily temperatures (>1σ), while it is very unlikely (90% confidence) that more than 60% of the global population will also experience the emergence of unfamiliar daily temperatures (>2σ).

WBS dictionary and checklist can also developed to safety planning. It shows that WBS complementary such WBS dictionary and checklist can be used for safety planning, and ease project construction’s life.
Mechanical properties of porous concrete and design recommendation for low traffic road pavement in Indonesia
Authors: Ramadhan G , Muslim F , Sagita L
Published: August 2021

Continued urbanization in the Greater Jakarta area has caused a narrowing of the catchment area due to land use focused on housing and office development. The use of porous concrete as a road pavement can be a remarkable potential to counteract this problem, allowing rainwater to penetrate the concrete, thus reducing runoff and increasing the groundwater level. The study aims to analyseporous concrete’s mechanical properties by looking at the influence of porosity level of concrete by 15% and 20% and the impactof maximum size aggregateused by 10 mm and 20 mm. This study’s mechanical properties include compressive strength, splitting strength, flexural strength, and shrinkage of porous concrete. The results show that porous concrete with an aggregate size of 10 mm has a splitting tensile strength and flexural strength greater than the 20 mm and a shrinking process faster than the 20 mm. Besides, porous concrete with a porosity level of 15% has compressive strength, splitting tensile strength, flexural strength more significant than 20%, and the shrinkage process faster than 20%. Finally, this study proposed a design recommendation on porous concrete for low traffic pavement. Based on the soil and rain data in Depok City, this study recommends 200 mm thickness of porous concrete layer, 225 mm thickness of subbase layer, HDPE pipe with 100 mm diameter, and 0.38 mm thickness of the impervious liner. Further research on the porous concrete design based on field study is urgently needed to prove the recommended design.

Published: August 2021

Indonesia is predicted to have 305 million of citizen by 2035 from the demographic bonus. Number of houses needed increases as well as its worthiness. Alternative ways of funding with private sector investment become top priority to provide public housing. However, some issues raise, i.e. project preparation period, hard to get financially feasible, and coordination complexity. Literature review and qualitative analysis are conducted. Main topics of the literature are public housing, infrastructure, private investment project, institutional, government effectiveness, and Indonesia existing condition. The qualitative analysis is used to find the relationship between literature to result the conclusion. Project preparation period and financially feasible should be solved by the function of private investment institutional which are central consultation and government support. Meanwhile, institutional integration can simplify the coordination complexity. The less the stakeholder number, the simpler the coordination.

Authors: Widiaputra Andyka Bayu , Arumsari Putri
Published: August 2021

In building construction projects there are 3 factors that are used to measure project performance, one of which is cost. Efforts that can be made to minimize the cost overrun are knowing the causative factors and knowing how to mitigate them. The purpose of this study is to identify the causative factors, determine the dominant factors causing cost overrun, and efforts to mitigate them. The methodology in this research is desk research or research that uses relevant secondary data analysis, such as previous research with similar problems. The results of this study were 65 causative factors divided into 10 groups. The dominant factor causing cost overruns includes material, implementation and employment relationships, project documents, and project finance groups, one of them is fluctuations in material prices. Mitigation efforts have been obtained for the dominant factor, namely quality control in the field must be good, selection of professional workforce, and building good relations between parties.
Seismic performance analysis of retrofitting building structure with type X bracing
Authors: Hidayat Irpan , Suangga Made , Suwondo Riza , Sami Muhamad
Published: August 2021

The result of the earthquake causes a lateral force that occurs on the building structure. Loads caused by earthquake loads need to be calculated and designed based on standards, so that when an earthquake occurs, the structure of the building is still able to resist the resulting lateral forces. The calculated building structure has a height of 12 floors with structural elements consisting of columns, beams, and shear walls. This building structure is loaded with earthquake loads which refer to SNI 1726-2019 Procedures for Earthquake Resistance Planning for Building and Non-Building Structures. Based on the calculation of the existing building structure due to the earthquake load of SNI 1726-2019, it was found that the story drift and Demand–Capacity Ratio (DCR) in column and beam did not meet the planning standards. The building structure was remodeled using type X bracing retrofitting to determine the value of story drift and DCR. Building structure modeling with type X bracing consists of three model shapes varying the location of placement and the number of type X bracing per floor. The results show that the addition of type X bracing can reduce the story drift up to 32.77% for the x direction and 33.75% for the y direction. In the cross-section of the beam element, the reduction in internal forces can reduce the Demand–Capacity Ratio (DCR) value in the beam. The cross-section of column element, the internal force has decreased but for the column which is attached to the type X bracing system showed an increase in internal force which causes an increase in the DCR value.
Analysis of clash detection and quantity take-off using BIM for warehouse construction
Authors: Elyano M.R. , Yuliastuti
Published: August 2021

Lack of integration in the design of a construction project planning, often resulting in clashes between elements. The purpose of this study was to analyze the number and causes of clashes between structural design, precast design, and MEP design for warehousing projects. Then the quantity take-off analysis will be carried out after resolving the clashes. In this study, BIM-based software was used namely Revit® 2020 and Navisworks® Manage 2020. The results of this study found that the number of clashes for the Structural vs Precast components was 289 clashes, for Structural vs MEP components was 191 clashes, and for Precast vs MEP components was 42 clashes. The cause of clashes with the highest percentage was caused by design error (52.36%), followed by design inconsistency (39.13%), and the last was a design discrepancy (8.51%). Based on the calculation of cost changes, a potential saving can be made for HCS panel material and for ducting pipe material as much as 10% of the initial cost.

Authors: Fata Yulia Amirul , Hendrayanto  , Murtilaksono Kukuh , Erizal
Published: August 2021

Vegetated slopes have variouslevels of slope stability. Variation of slope stability is affected by characteristics of vegetation, slopes, and soils which are shown by hydrological and mechanical (hydro-mechanical) effects. This article presents a review of the role of hydro-mechanical vegetation on slope stability asan explanation of landslide mechanism on vegetated slopes. The review showed that the hydro-mechanicaleffectsfrom rootsenhanced matric suction by evapotranspiration (ua – uw), change of volumetric water content by plant water uptake ( χ ), and enhanced effective soil cohesion due to root matrix reinforcement (CR), while vegetation and wind load canenhance surcharge (Sw) andenhance wind load force parallel to the slope (Fwind). Hydro-mechanical vegetation effects can increase or decrease slope stability depending on factors of slope steepness, root diameter, root depth, root area ratio, root morphology, soil aggregate, season or weather (wet, dry, snow), vegetation type, slope shape, location, and vegetation spacing.
Comparison of seismic load calculation based on SNI 1726-2012 and SNI 1726-2019 to capacity of elements on low level building
Authors: Hidayat Irpan , Loren Michael
Published: August 2021

Buildings are designed to resist earthquake loads. After an earthquake occurs, it is expected that buildings will suffer minimal non-structural and structural damage. In designing earthquake loads on buildings, the regulations used in Indonesia refer to SNI 1726-2012. In 2019, the national standardization body (BSN) issued a new standard in carrying out earthquake load planning on building structures. In this standard there is an update on the latest earthquake map based on past earthquake event data. This paper aims to compare those twostandards on low level building in terms of capacity of beams and columns using SAP 2000. The parameter of design spectral response at short periods, SDS anddesign spectral response at one seconds periods, SD1 has been increased as well in SNI 1726-2019 especially in Jakarta area, which resulted in greater base shear, story drift, and internal forces on the beam and columns. The analysis result showed that base shear of low-level building has increased by 4,98% in x-axis and 7,21% in y-axis. The internal forces caused by the earthquake load are compared with the cross-sectional capacities of the beams and columns. Since there are not significant changes inSDS andSD1 of Jakarta area, the impact on internal forces are minor which leads to result that all beams and columns still below the cross-sectional capacity of the beam and column.
Conceptual framework for the development of West Java Zero Waste Management Index
Authors: Sundana E J , Sutadian A D , Juwana I
Published: August 2021

Over the past decade, zero waste emerged as one of the promising concepts for waste management. Many parties have introduced this concept as a new way of waste management, aiming to reduce as little amount of waste generated as possible and send nothing to landfills. To measure the success of the zero waste implementation, some set of indicators have been developed. Although these were claimed to be successful after their implementation, very often they are not applicable to other regions or countries. Therefore, this study recommends developing the Zero Waste Management Index, which fits with local or regional conditions. This paper will discuss a framework for developing the West Java Zero Waste Management Index (WJZWMI). It will outline urban solid waste problem in West Java, and a brief review of existing zero waste indexes. Further, it will emphasize on the conceptual framework of the WJZWMI, which then results in potential long list indicators as preliminary results of this study, while also charting pathways for future works in developing a comprehensive zero waste management index for West Java Province.
Comparative study of Infrastructure Asset Management (IAM) between Papah irrigation areas in Indonesia and Cu-Chi irrigation areas in Vietnam
Authors: Cahyono C , Juliastuti
Published: August 2021

Infrastructure Asset Management (IAM) is implemented to overcome problems in the management of the agricultural sector. For example, in this study, the 2 research areas had similar problems, namely the poor water supply system in which the amount of water supplied did not match the initial design. To overcome this problem, IAM implementation in these two areas focuses on Integrated Water Resource Management. The objective of this implementation is that the ratio between the amount of water distributed and the one designed is close to 1 or the same. Based on the research results shown after implementing this IAM this problem was resolved. However, Cu-Chi Irrigation Area is still experiencing problems in the financial sector because the income from the sale of water supply is still far from the initial supply price. Whereas in Papah Irrigation Area this financial problem can be resolved with the implementation of the Irrigation Service Fee (ISF) and better management of the management company. Seeing this result, this ISF system can be applied to DI Cu-Chi to overcome the imbalance problem between the costs incurred for water supply and the revenue from the sale of the water.
Study of Modeling Method Selection in Flood Discharge Calibration Using HEC-HMS Software
Authors: Cahyono C , Juliastuti
Published: August 2021

Flood disaster management requires analysis and modeling, especially for the decision making of flood events. One way to analyze flood events is to use HEC-HMS software. HEC-HMS has three submodels: Loss, Transform, and Baseflow. In the flood discharge analysis, the selection of this sub-model is important because it is not certain that the method offered in this sub-model is suitable for all conditions, so it is necessary to choose which one is more suitable. Based on the results of the research, the SCS method can model well as evidenced by the good objective function values (RMSE (0.70 m; 49.05 m3 / s), Correl (0.931; 0.992), and DELTA PEAK (16.88%; 13.75%). The verification results are also show similar results (RMSE (0.63 m; 66,198 m3 / s), Correl (0.977; 0.916) and DELTAPEAK (43.04%; 32,754%). Therefore, it can conclude that the combination of benchmarking techniques that can be used for HEC-HMS modeling is the SCS curve number for losssubmodel, SCS unit hydrograph for transform submodel, and Recession constant for baseflowsubmodel.
Oblong Bridge Pier Shape Influence toward Flow Velocity Characteristic and Scour Depth
Authors: Pahlevi Casey Aufar , Setyandito Oki , Istiarto  , Sudiyono Kris Ade , Pierre Andrew John , Juliastuti
Published: August 2021

Flows that occur in rivers are usually accompanied by scouring/erosion and sedimentation/deposition processes. The scouring process that occurs can be caused by river morphological conditions and the existence of river structures that obstruct the flow. Structures such as bridge piers can change flow patterns so that in general can cause local scouring. One method for reducing the scouring that occurs around a bridge pier is to consider the shape of the pier bridge design. One of the most common pier bridge designs is the oblong shape. This research aims to find out the effect of streamlining the oblong pier shape on the change in flow characteristic and scour depth reduction using FLOW-3D numerical modeling.

Published: August 2021

The road condition should provide a decent level of comfort, safety and efficiency for the road users. One of the pavement performance parameters that can be determined objectively is the International Roughness Index (IRI). This research uses a relatively new technology to measure IRI value named the Roadroid, which is an android application developed from a Sweden company. Roadroid uses a built-in vibration sensor on a smart phone which is placed on the vehicle and produces output value in the form of IRI and speed values. Roadroid application obtained output data based IRI value and speed value with high accurately because used real-time data with each vehicle type which get through each road surface condition. Each type of vehicle produces an output of IRI values on different roadroid applications for each type of road surface damage which is influenced by various factors, one of which is the vibration sensitivity setting factor of the roadroid application system during the start calibration of the type of vehicle selection. The IRI and speed value based on the output of the roadroid application have a high correlation of 87.8% on medium car.

Published: August 2021

Indonesia has experienced rapid urbanization that has grown vastly in urban areas such as The Jakarta Greater Area. Since 2013, Jakarta Greater Area is also known as a megacity because of its populous population of above 26.7 million. The rapid growth of the population is the government’s responsibility to be able to provide adequate public facilities for society. This research aims to evaluate the spatial equity of 8 public facilities in the Greater Jakarta Area. The spatial equity can be an indicator of the adequacy level of the public facilities provided. This study used Moran’s I Spatial Autocorrelation (LISA Method). The research was divided into 5 stages consist of spatial data collection, layer creation process, count point in polygons, LISA, and spatial equity analysis. The goal of this research is to help urban planners to analyze which areas still need more public facilities. As a result, more than 700 areas are in the low-high area category, which indicates that the area has a high population, but the number of facilities provided is still insufficient.

One effort that is considered very effective by the company is by building and increasing Health Safety Environment(HSE) awareness for all oil and gas workers. The efforts made by companies to develop and increase HSE awareness are by providing HSE compulsory training. This study aims to study how much influence HSE training has on the prevention of the main risks of well service activities in the oil and gas industry. Data was taken from the questionnaire given to 100 respondents in the weld services. Data wasanalyzed using SEM AMOS (Analysis of Moment Structures) method. The internal data of the company has recorded a significant increase in the number of occurrences of workplace accidents caused by a lack of HSE awareness. The study has compiled a matrix of HSE compulsory training that should be provided to all employees to increase HSE awareness to avoid the risks of major risk well services such as explosions, explosions of Fire and Gas and oil spills. The results of the company’s internal analysis show that the lack of HSE training for new employees and old employees as refreshment was one of the root causes of lack of HSE awareness in the work environment. As a result, the provision of HSE training significantlyimproves to prevent the main risks of weld service activities.

In this paper, we report the successful development of non-thermal atmospheric plasma torch employing high voltage power supply. Usually atmospheric plasma is generated at high temperature (>1000 °C) and it is quite a challenge to generate cold plasma (<150 °C). The plasma torch in this assembly uses helium gas. The length of helium plasma glow discharge in this research is studied and optimized, with flow rate varied from 2 to 7 liters per mins, at varied applied voltage of 1.20 to 2.00 kV. The generated cold helium plasma has tunable length of around 5 to 35 mm, as cold as 26 °C. The plasma setup in this study is projected to be suitable for future applications in several fields such as industrial wastewater processing, as well as food processing, or agricultural field.

The current progress of information and communication technology has been critical to the development of the Internet of Things (IoT) in a aquaculture system. IoT solution in this system utilizes interconnectivity between devices to obtain fish pond monitoring data from sensing devices and then transmit the data to a remote server to be analyzed for decision-making in pond management. In this paper, we propose a smart pond IoT solution that provides a continuous and real-time pond monitoring. The system principally embeds five sensors that measure critical environmental parameters to determine water quality: temperature, pH, dissolved oxygen (DO), total dissolved solids (TDS), and salinity. The IoT solution also integrates the development of a mobile application on the android platform that allows remote monitoring capabilities for users to maintain efficient pond management. The application is designed with a friendly-user interface that helps the farmer to monitor sensor measurements, manage fish production cycle, record fish feeding schedule, and also monitor the health status of fish from multiple ponds.

Weeds are one of the organisms that interfere with plant growth. Information about the identity of weeds becomes very important on plantations. Although weeds data digitization has been done a lot, currently there is still not much weeds data information system can be accessed online. Weeds management is often dealt with weeds herbarium or weeds photographs.

In an effort to provide a good information system for farmers, this research aims to create a database of various types of weeds and an information system that can be accessed online. The methodology for developing a weed catalog information system uses the Software Development Life Cycle (SDLC). Weed samples in database were collected through systematic random sampling in the form of images and text. The result of this study is a Weeds Electronic Catalog or Weeds e-Catalog that can facilitate the information of weeds identity such as names, classifications, morphology, life cycles, and habitats of various types of weeds that grow on plantation land. Weeds e-Catalog can be used by plantation practitioners and farmers to make decisions in controlling weeds.

Aquascaping is a branch of art by arranging and creating a closed environment in an aquarium ecosystem. Aquascape uses living plants as the main element with fishes, shrimps, snails as the additional element. Plants need light to carry out photosynthesis. However, the light needed has certain parameters and quantities for each type of plants. If the light used is less than the needs of the plants, the plants will not grow up properly, however if the light given exceeds the ability of plants to absorb, algae will start to grow. In this study, an LED device that can emit the light needed by the plants will be developed. The light emitted by this device will be adjusted to the types of plants grown and the light around the aquarium environment. In this study, an application based on an android smartphone will also be developed. This will be used by users to choose the intensity of light that will be emitted by the device according to the type of plants grown in the aquarium. The device developed has been successful in maintaining the light emitted according to the light needed by the plants and the influence of light around the aquarium.

The transformation of sensory description of vanilla extract after it reaches the expiration date is caused by the changes in its flavor compounds. The aim of this study is to analyze the density, flavor compounds and sensory description in vanilla extract before and after the expiration date, quantitatively. Densities were measured using density meter, flavor compounds were measured using gas chromatography-mass spectrometry (GC-MS) and sensory descriptions of vanilla extract were observed using the sensory analysis of Quantitative Descriptive Analysis (QDA) by trained panellist. The results showed that the density of vanilla oleoresin increased during storage. Moreover, the GC-MS results showed that there were several flavor components that only existed on expired samples, such as 4-methyl guaiacol, anisyl ethyl ether, and anisic acid. However, there was no significant difference in vanilla extract sensory description, except for anisic attribute, where the expired vanilla extract was more anisic.
