Published: December 2021

Abstract
The main pest in the Cucurbitaceae family is the fruit fly. The common effort to control fruit flies is using a trap with methyl eugenol (ME) and cue lure (CUE) as an insect attractant. The trap height installation is also affecting the fruit fly population. The fruit fly population in the field has an important effect on the damage intensity in the commodity. This research objective was to study the distribution and diversity of fruit fly on the cucumber field with trap height installation and attractant combination. The used research method was Factorial Group Randomized Design (RAKF). The first factor was attractant combination of Metil Eugenol (ME) and Cue Lure (CUE) consisted of 6 treatment levels were K1 : 5 mL ME, K2: 5 mL ME + 1 mL CUE, K3: 5 mL ME + 3 mL CUE, K4: 5 mL ME + 5 mL CUE, K5: 5 mL ME + 7 mL CUE and K6 : 5 mL CUE. While the second factor was the high tramp installation consisted of 3 treatment levels were T1: 50 cm, T2: 100 cm, and T3: 150 cm. The treatment consisted of 3 replication on three different cucumber fields. The result showed discovered fruit fly species were eight species, B. dorsalis (Hendel), B. carambolae Drew & Hancock, B. occipitalis (Bezzi), Z. caudata (Fabricius), B. umbrosa (Fabricius), B. neocognata Drew & Hancock, Z. cucurbitae (Fabricius) and B. albistrigata (de meijere). The dominant fruit fly in each treatment in fruit fly fields was B. dorsalis (Hendel). The best treatment in trapping fruit fly was K1 (5 mL ME) with trap height installation T1 (50 cm). The diversity and species richness of fruit fly in the cucumber field was considered low and uneven.

Abstract
Currently, renewable energy started to become a focus of the world as it can be an alternative to fossil energy. Bioethanol is the result of glucose fermentation derived from lignocellulosic raw material (second-generation bioethanol). As one of the countries with the most significant biomass resources globally, Indonesia has a huge opportunity to develop the bioethanol industry. Oil Palm Empty Fruit Bunch (OPEFB) is the most significant solid waste generated by oil palm plantations. Levulinic acid can be used as a chemical platform for biodiesel production, which has a higher selling price than bioethanol. In this research, techno-economic evaluation of integrated levulinic acid-bioethanol plant based on OPEFB was conducted. Optimization of production capacity is done to determine the suitable plant capacity so that the integrated levulinic acid-bioethanol plant is feasible to be developed. Based on simulation results with SuperPro Design 9.5 and analysis of the economic value, Net Present Value (NPV), Internal Return Rate (IRR), and the payback period is 53.939.000 USD; 29,77%; and 4,52 years, respectively. In conclusion, an integrated levulinic acid-bioethanol plant based on OPEFB has fulfilled the economic parameters of a chemical plant.

Authors: Amni C , Marwan  , Aprilia S , Indarti E 
Published: December 2021

Abstract
Three-dimensional printing (3DP) provides a fast and easy fabrication process without demanding post-processing. 3D-bioprinting is a special class in 3DP. Bio-printing is the process of accurately 3DP structural design using filament. 3D bio-printing technology is still in the development stage, its application in various engineering continues to increase, such as in tissue engineering. As a forming material in 3D printing, many types of commercial filaments have been developed. Filaments can be produced from either natural or synthetic biomaterials alone, or a combination of the two as a hybrid material. The ideal filament must have precise mechanical, rheological and biological properties. Polycaprolactone (PCL) is specifically developed and optimized for bio-printing of 3D structures. PCL is a strategy in 3D printing to better control interconnectivity and porosity spatially. Structural stability and less sensitive properties environmental conditions, such as temperature, humidity, etc make PCL as an ideal material for the FDM fabrication process. In this review, we provide an in-depth discussion of current research on PCL as a filament currently used for 3D bio-printing and outline some future perspectives in their further development.
Bamboo fiber-PLA composite materials for disposable food and beverages packaging tools: a brief review

Published: December 2021

Abstract
Disposable packaging tools such as cups/food containers have become popular and commonly used items in today’s society as they offer simplicity, low cost, durability, and convenience for people in carrying/taking their foods. Most of these packaging tools are non-biodegradable products because their materials are mainly composed of plastics and/or their derivatives. Consequently, packaging tools have become one of the primary contributors to the earth’s waste and global warming. Eco-friendly products can be defined as products that are safe and healthy for individuals and communities throughout their life cycle, which includes all processes from production to consumption and up to disposal. Current methods for developing eco-friendly products have mainly relied on using composites of different biodegradable materials that are chosen and combined in such a way that they can complement each other’s weakness or drawback. One of these composites with the potential to replace and address the negative impacts caused by plastics products is the bamboo fiber-PLA (BF-PLA) composite. This paper is intended to briefly discuss the characteristics of as well as various important properties of such a BF-PLA composite to illustrate and motivate its potential future use as an alternative eco-friendly material for producing disposable packaging tools.

Abstract
Diabetes mellitus (DM) is a disease characterized by hyperglycemia due to decreased insulin secretion, or decreased insulin sensitivity, or both. If insulin is not available or the amount is low, then glucose cannot enter the cells and will continue to be in the bloodstream. DM can cause chronic complications such as eye complications, skin infections and stroke. DM treatment takes a long time by using synthetic drugs that will cause side effects, therefore the search for herbal-based drugs is the community’s choice. Idat plant (Cratoxylum glaucum) is a local plant from Bangka Belitung. Several studies on the genus Cratoxylum from China and Thailand showed a very high inhibitory ability against the inhibition of a-glucosidase enzymes, protein tyrosine phosphate, and carbohydrate hydrolysis enzymes because they contain phenolic compounds anthraquinones and xanthones. Therefore, the importance of more intensive research on C. glaucum species regarding the content of secondary metabolites in C. glaucum stems and their antidiabetic power. The extraction method in this research is maceration with ethyl acetate solvent. Qualitative examination of phenolic and flavonoid content using reagents, as well as antidiabetic testing was carried out in vitro with dengan α-glucosidase enzyme inhibition method. Based on qualitative testing of phenolic and flavonoid compounds, the content of these compounds was obtained. antidiabetic test showed that the-glucosidase inhibitor of ethyl acetate extract had very strong activity with an IC50 of 4.21 g/mL. Therefore, the stem of the idat plant can be used as a therapy for the treatment of diabetes mellitus.

Abstract
With the rapid development of cities around the world, the concept of ecological design of large-scale public buildings has gradually come to the attention of the public. One of the main problems is the possibility of maintaining a balance between urban development, nature and man, which creates conditions for improving the environment and improving the quality of life of the population. An ecologically comfortable environment is considered today as one of the main prerequisites for the development of a particular territory. This article first gives a brief overview of scientific sources on the design of public buildings in botanical gardens, then discusses the principles of environmental design of large-scale public buildings and, finally, review the ideas of environmental design of greenhouse buildings in Russian botanical gardens from two aspects of form and content. The relevance of the work is ensured by the fact that botanical gardens occupy an important place in any city and it is necessary to understand how to update the garden space, how to respond to the new requirements of society and by what means to attract more visitors. Based on the analysis of various examples, the author notes the existing problems of construction of large-scale public buildings of eco-friendly design in Russian botanical gardens, and also comes to the conclusion that the landscape architecture of Western Europe and the experience of Western engineers in eco-friendly construction has a great influence on the image of modern Russian botanical gardens.

Abstract
The main objective of the paper is to investigate the feasibility of small-scale grid-connected PV systems with various PV technologies (mono-crystalline silicon and poly-crystalline silicon) and sun-tracking modes including fixed tilt and 2-axis systems for rooftop households in Amman, Jordan. A case study is applied to Al Jama’a and Abu Nusir, Amman, Jordan. Typical households were chosen for this region to establish a load profile according to monthly electrical bills. The results show that the annual electrical energy from fixed small-scale PV panels tilted at an optimal angle was ranged from 3499.04kWh to 8811.62kWh, while the annual electrical energy from the PV tracking system was within the range of 4788.05-12128.30kWh. This amount of energy output would contribute significantly to reduce fossil fuel consumption and CO2 emissions in the country. Moreover, it is found that the highest energy consumption can be covered by PV systems is recorded in winter. Also, the average energy production cost is ranged from 0.0444-0.0530$/kWh for all proposed systems based on the financial assumptions used in this study. It is concluded that the small-scale grid-connected rooftop PV systems are found to be economically justifiable.
Kinetic evaluation of methylene blue decolorization by CuO as a Fenton-like catalyst

Published: December 2021

Abstract
The presence of dyes in wastewater is one of the main problems in wastewater treatment. Wastewater containing dyes can damage the ecosystem because it can block sunlight into the water and is often accompanied by toxic materials. This paper proposes an alternative method to decolorize dyes in water using CuO as a Fenton-like catalyst, especially for wastewater contaminated by methylene blue dye. The Fenton method is an advanced oxidation process method with a radical group of H2O2 acting as the primary decolorizing agent. By measuring the concentration using a UV-Vis spectrophotometer, we found that the proposed decolorization method effectively degraded the color of methylene blue. To understand the decolorization mechanism, we investigated the reaction kinetics of the decolorization process. We found that compared to the pseudo-first-order and second-order reaction kinetics models, the BMG model had higher accuracy and conformed to the color concentration degradation curve.

Published: December 2021

Abstract
PT Timah Tbk has been processing residual ore (SHP) with a low tin grade of ± 10-30% wt. To increase tins grade and associated mineral products to be a high grade (> 70% wt), an evaluation and optimization process is needed on Induced Roll Magnetic Separator processing equipment. The evaluation and optimization process was carried out on magnetic products, especially ilmenite minerals. Sampling is done on the feed and the product based on the tool parameter settings. The feed rate is set at 380, 320, 250, 420, and 470 gr/10s. The splitter opening is set at 10, 15, 20 mm of magnetic rollers. While the electric current is set at 2, 4, 6, 8, 10, 12, 14 amperes. Mass and grade data are then analyzed by regression and variance statistical methods and optimized by the response surface method. The evaluation results show that only the splitter opening parameters and electric current strength are significant in explaining the product results obtained with a level of hypothesis error of 5%. The results of IRMS optimization show that the best parameter conditions are in the 2-4 ampere of electric current and 10-15 mm of splitter openings with illmenite grade capable of> 80% wt in the second order of central composite design.
Seawater Intrusion Assessment based on Hydrochemical Data in Gapura Sub-district of Sumenep Regency, East Java, Indonesia
Authors: Warist R K , Wilopo W , Setiawan N I 
Published: December 2021

Abstract
Gapura is a sub-district with a large salt pond in Sumenep Regency, Madura Island, Indonesia. In this area, many residents’ houses have drilled wells to meet their water needs. One factor is that Municipal Waterwork (PDAM) does not reach the area due to limited water sources and difficult accessibility. Residents in the area claimed to have found some groundwater that tasted brackish. This study aims to apply hydrochemical analysis to identify the possibility of seawater intrusion in the area. The assessment of seawater intrusion uses the total dissolved solids (TDS) value and major ion of groundwater samples. In the analysis of thirty samples, two samples have different values from the samples of freshwater. However, the value of these two samples is relatively low to be classified as seawater intrusion. It is described on the TDS values that belong to the class of brackish water, from Simpson ratio values classified as slightly contaminated, and from the piper diagram plot that is still in the mixing zone in the middle of the diagram. The presence of brackish water in these samples can be caused by a location close to salt pond activities.
Settlement Negotiations with Reference-Dependent Preferences
Authors: Rössler Christoph , Friehe Tim 
Published: December 2021

Abstract
This article analyzes pretrial bargaining between litigants with reference-dependent preferences. We build on Bebchuk (1984, “Litigation and Settlement under Imperfect Information,” 15 Rand Journal of Economics 404–15) and, motivated by empirical evidence, assume that the referent is based on expectations. We find that reference dependence on behalf of plaintiffs increases the settlement probability. The fact that preferences are reference-dependent meaningfully influences comparative statics predictions. In our extensions, we discuss the role of fee shifting, the effect of having the referent based on the status quo instead of on expectations, and risk aversion.
The Status of Chinese State-owned Enterprises in International Investment Arbitration: Much Ado about Nothing?
Authors: Du Ming 
Published: December 2021

Abstract
Chinese State-owned enterprises (SOEs) play a key role not only in China’ domestic market, but also in implementing the Government of China (GOC)’s ambitious Belt and Road Initiative. Accordingly, Chinese SOEs have increasingly fallen back on investor-State investment arbitration to protect their investments in host States. A recurrent issue arising in arbitral proceedings concerns whether Chinese SOEs should be allowed access to investor-State dispute settlement mechanisms in view of the close links between Chinese SOEs and the GOC. This article sets forth two arguments. First, applying the relevant ILC Articles to Chinese SOEs, the article makes a legal argument that it is highly unlikely for a Chinese SOE to be denied standing as a qualified claimant in investor-State arbitration. Second, notwithstanding concerns about Chinese SOEs in the global investment landscape, the article makes a policy argument that the denial of Chinese SOEs’ standing before arbitral tribunals is not only unhelpful in addressing those concerns, but also undermines the rule of law in international investment.

Published: December 2021

AbstractThe Infectious Diseases Society of America (IDSA) is committed to providing up-to-date guidance on the treatment of antimicrobial-resistant infections. A previous guidance document focused on infections caused by extended-spectrum β-lactamase–producing Enterobacterales (ESBL-E), carbapenem-resistant Enterobacterales (CRE), and Pseudomonas aeruginosa with difficult-to-treat resistance (DTR-P. aeruginosa). Here, guidance is provided for treating AmpC β-lactamase–producing Enterobacterales (AmpC-E), carbapenem-resistant Acinetobacter baumannii (CRAB), and Stenotrophomonas maltophilia infections. A panel of 6 infectious diseases specialists with expertise in managing antimicrobial-resistant infections formulated questions about the treatment of AmpC-E, CRAB, and S. maltophilia infections. Answers are presented as suggested approaches and corresponding rationales. In contrast to guidance in the previous document, published data on the optimal treatment of AmpC-E, CRAB, and S. maltophilia infections are limited. As such, guidance in this document is provided as “suggested approaches” based on clinical experience, expert opinion, and a review of the available literature. Because of differences in the epidemiology of resistance and availability of specific anti-infectives internationally, this document focuses on the treatment of infections in the United States. Preferred and alternative treatment suggestions are provided, assuming the causative organism has been identified and antibiotic susceptibility results are known. Approaches to empiric treatment, duration of therapy, and other management considerations are also discussed briefly. Suggestions apply for both adult and pediatric populations. The field of antimicrobial resistance is highly dynamic. Consultation with an infectious diseases specialist is recommended for the treatment of antimicrobial-resistant infections. This document is current as of 17 September 2021 and will be updated annually. The most current version of this document, including date of publication, is available at www.idsociety.org/practice-guideline/amr-guidance-2.0/.
Primary hyperoxaluria type 1: novel therapies at a glance
Authors: Bacchetta Justine , Lieske John C 
Published: December 2021

ABSTRACT
Primary hyperoxaluria type 1 (PH1) is a rare and severe autosomal recessive disease of oxalate metabolism, resulting from a mutation in the AGXT gene that encodes the hepatic peroxisomal enzyme alanine–glyoxylate aminotransferase (AGT). Until recently, treatment of PH1 was supportive, consisting of intensive hyperhydration, use of crystallization inhibitors (citrate and neutral phosphorus), in a subset of responsive PH1 patients’ pharmacologic doses of vitamin B6 (pyridoxine), and kidney and liver transplantation when patients progressed to kidney failure. Treatment approaches have been similar for PH2 caused by mutations in hepatic glyoxylate reductase/hydroxypyruvate reductase (GR/HPR), although pyridoxine does not have any benefit in this group. PH3 is caused by mutations of mitochondrial 4-hydroxy-2-oxoglutarate aldolase (HOGA1) and was the most recently described. Kidney failure appears less common in PH3, although kidney stones occur as frequently as in PH1 and PH2. Oxalate metabolism in the liver is complex. Novel therapies based on RNA interference (RNAi) have recently emerged to modulate these pathways, designed to deplete substrate for enzymes upstream and decrease/avoid oxalate production. Two hepatic enzymes have been targeted to date in PH: glycolate oxidase (GO) with lumasiran and lactate dehydrogenase A (LDH-A) with nedosiran. Lumasiran was approved for the treatment of PH1 in 2020 by both the European Medicines Agency and the Food and Drug Administration, whilst clinical trials with nedosiran are ongoing. Results with the two RNAi therapies demonstrate a significant reduction of urinary oxalate excretion in PH1 patients, but long-term data on efficacy (preservation of kidney function, decreased stone events) and safety remain to be established. Nevertheless, the hepatically targeted RNAi approach represents a potential ‘game changer’ in the field of PH1, bringing hope to families and patients that they may be able to avoid liver and/or kidney transplantation in the future and suffer fewer stone events, perhaps with less strict therapeutic regimens. Pharmacological compounds directly inhibiting GO or LDH are also under development and could be of special interest in developing countries where RNAi therapies may not be readily available in the near future. Approaches to manipulate the intestinal microbiome with a goal to increase oxalate degradation or to stimulate secretion of oxalate into the intestine from plasma are also under development. Overall, we appear to be entering a new phase of PH treatment, with an array of promising approaches emerging that will need optimization and evaluation to establish long-term efficacy and safety.
