Authors: Fitriarni D , Martanto  , Rifkowaty E. E. 
Published: December 2021

Abstract
Wedang empon is a rhizome-based drink, one of the most popular functional drinks in Indonesia. This drink is consumed as a drink that is believed to increase the body's immunity and maintain a healthy body. This is due to the potential content of secondary metabolites contained in it. The purpose of this study was to combine empon-based drinks with several types of fruit and flower extracts. The development of this empon-based drink was carried out to provide variations in taste, aroma, and color as well as its nutritional content. Therefore, in this study, wedang empon drink which has been combined with several fruits and flowers was analyzed for product quality with several parameters such as phenol content, vitamin C, and product hedonic tests to find out how consumers respond to the resulting product. In this study, an analysis of the moisture content of the dried product was also carried out to ensure that the water content was within the permissible limits. The research started from material preparation, formulation, characterization and product analysis. Based on the results of the analysis, it was found that in general the yield value of the water content was less than 10%. Overall, the total phenol content of all treatments ranged from 14.75-43.32 mg GAE 100 g-1 and the highest total phenol content was detected in the combination of rosella with wedang empon ingredients. The amount of vitamin C ranged from 42.1013-107 mg/100 g and samples of wedang empon mixed with lakum were the highest. Hedonic test results ranged from 63.556 to 90.667, taste ranged from 63.556 to 90.667, aroma number ranged from 67.11 to 79.556, then color ranged from 70.222 to 84,889. This means that there are differences in the effect of adding different ingredients to the taste of wedang empon. By mixing the rhizome drink with fruit and flower extract will help improve the sensory properties of the drink so that this drink can be more accepted by many consumers of all ages or for those who don't even like the unpleasant smell of wedang empon drinks.

Rice millings operate in the Regency to process raw rice into rice (hulled rice), and become a central point in the rice agro-industry and institution that connects actors in the supply chain, starting from raw rice to producing hulled rice as the main product. The aim of this research is to: (1) analyze supply chain mechanisms related to product flows, information flows and financial flows on rice; (2) analyze added value received by actors in the rice supply chain network; and (3) analyze marketing efficiency of rice in West Lombok Regency. This research uses descriptive methods. Data collection was carried out using surveys to the research locations of the districts of Narmada, Lingsar and Gerung, which all are the centers of rice in West Lombok Regency. There were 30 rice farmer respondents and some institutions or individuals involved in the flow of rice from farmers to end consumers. Data were analyzed by applying the analyses of descriptive, added value, and marketing efficiency. The results showed that in the rice supply chain there have been flows of product, finance, and information, amongst marketing actors or institutions. The added value and profit resulting from processing unhulled rice to hulled rice were IDR 6,100/kg and IDR 5,850/kg, respectively. It was also found that in West Lombok Regency there are three patterns of marketing channels and all of the channels operated efficiently.

Abstract
The evolution of webs from web of documents to a web of data allows machines to read and connect structured data on the Web, known as Linked Data. This enables machine learning to use linked data in ways that were previously thought to be impossible to do. Machine learning and linked data research are relatively thoughtless. As a result, the primary goal of this research is to present ARQL, an extension of SPARQL 1.1 and to cluster Linked Data derived from online web sources. We provide state of the art ARQL features to allow machine to directly query from online RDF, JSON-LD or JSON API. Here we describe how ARQL web service is used to query Web of Data development and generalization of SPARQL federated query, two initial steps for the development of halal food mobile application tied up with ARQL.

AbstractThe Mandalika Special Economic Zone (SEZ) was designated as a tourist area in 2015. The development of the Mandalika area directly impacts the sustainability, diversity of species, especially birds that make mangroves their habitat. The study aims to investigate the value of bird species diversity in mangrove habitats as bioindicators. Furthermore, the research has been carried out for three months, from March to May 2021. Research data collection uses the roaming method, and data analysis uses bird community structure analysis (Diversity Index). In this study, 33 species of birds were found. Furthermore, it was found that six species of birds are protected wildlife. In addition, 16 are migratory birds, and 27 are Least Concern (LC) bird species; four species have Near Threatened (NT) status. Meanwhile, the Index of bird community structure is H’ 2.7, uniformity E 0.8, and dominance C 0.9. The value of the bird community structure in the Mandalika SEZ shows the condition of mangrove habitat in the moderate damage category. Therefore, there needs to be an effort to preserve mangroves involving the community, government, and Indonesia Tourism Development Corporation (ITDC) area managers.

Abstract

D.lineale is included in the CITES appendix II due to D. lineale has great potential as a cut flower and the parent of hybrid orchids. In vitro culture can be used for mass propagation of orchids for commercial breeding as well as conservation. Basic culture medium with the addition of organic substances can increase the growth of plantlets. The objective of this research was to determine the best condition for in vitro culture of D.lineale orchids for producing a mass number of plantlets. Methods used include planting orchid seedlings in various variations of culture media, plantlet subcultures, observation of the anatomy of leaves and roots, as well as the measurement of chlorophyll content. This research uses ‘pisang raja’ as organic material in the culture medium. The highest chlorophyll content in the leaves was 1.58 mg/g, while the highest chlorophyll content in the roots was 0.34 mg/g. Both were found in medium NP+100 g/L bananas in light conditions (1317 lux). The anatomical structure of the leaves shows that the mesophyll is thicker in plants placed under lighting 1317 lux because it shows good effectiveness in photosynthesis. The anatomy of the orchid roots showed differences in diameter in each treatment because the addition of bananas to the medium stimulated rapid and abundant root formation, but the size was smaller. Based on these results, it can be concluded that the addition of 100 gr/L bananas as organic substances in in vitro medium culture increases the growth rate of D. lineale orchids, which will be beneficial for conservation efforts.

AbstractThe polymerase chain reaction (PCR) has been used for molecular research to amplify DNA fragments, especially from a small amount of genetic material. PCR has been applied for numerous researches, including for plant molecular identification. A good PCR product is dependent on good amplification of the DNA segment in optimum condition. This research was conducted to optimize the primer combination, and the annealing temperature for DNA barcoding application of Balinese rare medicinal plant(Euchresta horsfieldii(Lesch.) Benn.) collected from Bedugul. COI is a suitable primer to identify unknown species to higher taxa levels and species with high phenotypic plasticity. The range of annealing temperatures was tested to amplify the combination of five COI primers: GWSF and GWSF5 for forwarding primers and GWSR, GWSR3, and GWSR5 for reverse primers. The annealing temperature was 52, 54, 56, 58, 60°C for 30 seconds. The result showed that GWSF-GWSR, GWSF-GWSR5, GWSF5-GWSR, GWSF5-GWSR5, and GWSF5-GWSR3 produced multiple bands, the double band that cannot be cut, multiple bands, faint amplification band for GWSF5-GWSR5 and GWSF5-GWSR3, respectively. Primer combination of GWSF-GWSR3 with an annealing temperature of 52°Cproduced double bands that were available to have proceeded for sequencing. In conclusion, the combination of GWSF-GWSR3 that is annealed at 52°C produced the best amplification band. The primer combinations and conditions can be used for further identification of Purnajiwa collected from Bedugul.

Abstract
The high level of ammonia and nitrite is a toxic factor for both poultry and aquaculture animals that directly lead to lower economic benefits. Thus, reducing ammonia and nitrite levels is an essential key for successful culture and is also important to reduce the amount of ammonia and nitrite released into the environment. This study aimed to screen bacteria having a capacity to degrade either ammonia or nitrite in vitro. Five bacterial strains previously isolated from broiler chicken (Gallus gallus domesticus) intestine and pond sediment of Nile Nilapia (Oreochromis niloticus) were used in this study, namely IBP-1, IBP-2, IBP-3, IBP-4, and IBP-5 strains. The screenings were performed using either NH4Cl containing medium or NaNO2 containing medium to determine the ability of bacteria to reduce ammonia or nitrite respectively. The ammonia and nitrite levels were afterwards measured at the beginning (day 0: before bacterial inoculation), 24h (day 1), 48h (day 2), and 72h (day 3) after the addition of 1 ml of the bacterial suspension. The results showed that the five bacterial isolates were able to degrade the ammonia and nitrite content. The greatest reduction of ammonia was achieved by IBP-4 strain (0.00 mg/l), followed by IBP-5 strain (0.04 mg/l), IBP-1 strain (0.05 mg/l), IBP-3 strain (0.14 mg/l) and IBP-2 strain (0.19 mg/l). IBP-1 and IBP-2 strains showed the highest reduction of nitrite levels with values of 0.01 mg/l and 0.02 mg/l after 72h of bacterial inoculation. These results suggest that the five bacterial strains are potentially used for degrading toxic ammonia and nitrite.

Abstract
In some cases, the immune system in COVID-19 patients leads to the release of excess cytokine production (cytokine storm), which will potentially develop into pneumonia. Interleukin 6 (IL-6) plays the role of pro-inflammatory cytokine, it is a receptor mediated signalling system. Macroalgae is well known as a source of valuable bioactive substances with potential biological activities. Among them is the sulphated polysaccharide lambda-carrageenan λ-CGN which has been reported as an anti-inflammatory agent. However, its mechanism of action against IL-6 production is currently unknown. This study aims to predict potential molecular mechanisms of λ-CGN chemical compound against IL-6 expression through in silico study. Chemical compound of λ-CGN and target protein in this study were obtained from the pubchem and protein data bank (PDB). The molecular docking prediction was conducted with PyRx software, the result is λ-CGN compound showing strong binding energy to bind target protein IL-6 receptor with the value of -5.9 kcal/mol. Based on the results of in silico study, the sulphated polysaccharide λ-CGN potentially inhibits IL-6R expression by binding ligand pocket with six conventional hydrogen bonds (amino acid residus: His256, His 257, Trp 219, Arg 231, and Asp 221) and two carbon hydrogen bonds (amino acid residus: THR 218 and GLN 220). Binding with these amino acid residues potentially contributes to IL-6 receptor structural change which could result in functional change. Hence, further studies related to in vitro and in vivo investigations would be interesting to further understand the inhibitory mechanism of λ-CGN against IL-6.
Freight shipper’s mode choice preference for sustainable inland transportation
Authors: Firdausiyah N , Chrisdiani D P 
Published: December 2021

Abstract
Modelling of transport mode choice preferencehas beencurrently regarded essential to identify the preference of transport agents towards a transport policy. This research proposes a model of the freight mode choice preference by using Stated Preference Methods for the data collection from industrial freight shippers in Gresik, Indonesia. This research examines how truck as an existing mode and rail as a sustainable mode alternative compete for goods movement. As the common feature of discrete choice models, the Binary Logit was utilized to analyze the data. The sensitivity of mode preferences was investigated by changing the shipping cost and hauling time. The results indicated that the respondents were sensitive to haul time and shipping cost. When the shipping cost and hauling time was similar, the probability of choosing a truck was 77%. However, the industrial freight shippers changed the preference when the truck’s shipping cost and haul time was higher than that in the train. The train had a 65% choosing probability when the cost difference was IDR 500,000 lower and the hauling time difference was two days faster than the truck. This study assisted the policymakers to correctly design the variables of shipping cost and hauling time for the future sustainable inland transportation based on freight shipper’s preferences.
Beyond the informal settlement: the land tenure situation of urban kampungs in Surabaya, Indonesia
Authors: Tauran T 
Published: December 2021

Abstract
Kampung occupies a significant role in urban settlements in Indonesia. The existing studies categorise urban kampung as informal settlements. However, using evidence from urban kampungs in Surabaya, this study rejects the perspectives that simplify urban kampungs as informal settlements. This study proposes a critical feature of informal settlement as a gauge: land tenure. The findings show that urban kampungs are too complex to be represented in the informal category. Urban kampung can be inhabited by residents with various land tenure beyond formal and informal dichotomy. Most urban kampung residents occupy land with the state (national) or customary tenure, which the state and society recognised. Administratively, they are also integrated into the city government services. Based on the findings, this study argues that simplifying urban kampungs into the informal settlement category is imprecise and potentially misleading.

Published: December 2021

Abstract
The government of Malang city has developed public space by increasing the number of city parks and revitalising the existing parks, functioned as active parks and city forests. Despite the development of individual city parks, about the debate has circulated regarding how the parks are integrated with the city’s spatial system. The focus of this research comprises the evaluation of city parks performance according to the parks’ relative position in the city’s spatial system. This study applies the two variables, including: the relative position of city parks and the visit frequency. The relative position is identified by employing the notion of spatial configuration and space syntax. The visit frequency is explored by utilizing questionnaires. The correlation between the two variables is investigated by using Pearson Product Moment. The research indicates that there is a correlation between the two variables. This finding additionally proves that the spatial configuration determined access to city parks, thereby encouraging the visits. Further, this study has navigated some other motives for the visits in addition to the access.

Abstract
COVID-19 has brought a massive impact on people’s daily activities, office workers have implemented “Working from Home” (WFH), an elementary school to high school students have implemented “Study from Home” (SFH), as well as Campus academic communities’ activities’ implementing Learning from Home. This circumstance has changed daily human behavior for a year. In 2021, upon the completion of a global vaccination program, the situation is followed by a change in the pattern of daily living activities towards “a new normal”, in which direct human interaction is reinstated while still fulfilling health protocols, one of the actions is social distancing. This study examined the detection of pedestrian traffic for the academic community of the Department of Urban and Regional Planning (DURP), Brawijaya University and predicted certain crowds’ spots in the DURP building, using Computer Vision and the integration of Agent-Based Model and Geographical Information Systems Indoor. Furthermore, alternative designs for pedestrians were carried out in the DURP building to prevent the occurrences of crowds in certain spots. The results obtained are that on the 1st Floor of the DURP building, the West and East entrance paths have high traffic, so it is necessary to arrange for the opening of the Southside door as an alternative for pedestrian access. Likewise, for the 2nd Floor, the opening of the south gate contributes to minimizing crowd spots. All in all, the blended learning process through face-to-face learning at students grades 1 and 2, then online learning at students grades 3 and 4 might minimize the potential Covid-19 transmission facing a new normal higher education learning process.
