The increasing use of recycled paper by the paper industry to support the Green Industry in the Indonesian Pulp and Paper Industry. But technically, there are some disadvantages of recycled fiber usage such as low drainage rate in which boosted the high energy consumption on drying process. As already known, the drying process consumes the highest energy in papermaking. To overcome this problem, the research using the concentrate of endoglucanase Egl-II has done. The steps of research included production of endoglucanase Egl-II; concentration by ultrafiltration method, modification of recycled paper fibers using endoglucanase Egl-II; characterization of paper sheet; and evaluation of energy consumption in drying the sheet of paper. The results showed that endoglucanase Egl-II had increase drainage rate of recycled fiber stock, which indicate by the freeness number. The number had increased by 80 ml CSF (Canadian Standard Freeness) from 190 ml CSF to 270 ml CSF, and fiber retention increased by 0,63% from 99,31% to 99,94%. The dissolved cellobiose test results of recycled fiber stock by the enzyme treatment at low dosage showed that no degradation of cellulose, no change into soluble sugars. Characterization of sheet of paper that has been modified with endoglucanase Egl-II based FTIR spectra showed no change in functional group, SEM results showed on the fiber surface fibrils grow more, and the results of the XRD analysis showed area reduction of amorphous regions is about 6%. The potential for energy efficiency is calculated through thermodynamic approach is about 15%. [ABSTRACT FROM AUTHOR]

Abstract: Using the Kobe earthquake of 1995 and the Mid-Java earthquake of 2006 as case studies, this paper discusses the process of providing cultural recovery assistance; it also analyses the term ‘civil society’, a term that reflects efforts to make assistance activities sustainable. The Kobe earthquake should be seen as a point of departure for citizen activism by volunteers; because of it, cultural recovery support was vigorously provided. Since people influenced by those support efforts later became involved in providing Mid-Java earthquake recovery assistance, both earthquake recovery support initiatives can be seen as part of an ongoing chain of events. In analysing the Kobe earthquake, it becomes clear that while there are many semantic meanings for and usages of the term ‘civil society’, it was incorporated into policy guidelines for recovery during a period of low economic growth, and a new civil society was envisioned in this period of social transformation. Organisations participating in assistance efforts following the Mid-Java earthquake sought to make ‘civil society’ a reality; this continued after the earthquake recovery was complete, and it comprised an attempt to build the connections within a civil society by looking to overcome many persistent social problems. The power of communication that ‘culture’ holds plays a large role in this. [ABSTRACT FROM AUTHOR]

Recent work on scale, chronotope and scale-making offers exciting ways for rethinking what we often refer to as "context". In this paper, we review these ideas pointing to how we might reconcile some of the overlaps in the concepts of scale and chronotope, while examining how we might look at chronotopic connection across quite different empirical divides drawn from a number of separate research projects in Indonesia. We propose that scale can be thought of as chains of chronotopes and that the semiotic forms that connect them as scale-makers, thus helping relate these two concepts to that of scale-making. • Explores how overlaps in the literature on scale, chronotope and scale-making might be reconciled. • Examines chronotopic connections across quite different empirical divides. • Explores how imitations connect chronotopes.

In a circular economy, extended producer responsibility (EPR) is a regulatory approach that accounts for all environmental costs associated with a product throughout its life cycle. When considering the EPR, the regulator must (1) design an integrated framework for different stakeholders and (2) provide effective policies to create financial incentives to accelerate the circular system. Recycling funds and subsidies are the most prominent financial strategies that can either encourage or curtail the flows of recycled products. In Indonesia, a few companies provided recycling bonus s to their customers as incentives to increase the recycling rate. However, the recycling rate was not as effective as expected by the enterprise because recycling was practiced by a limited number of companies, rendering it economically unviable. The enterprises hope the government could develop a recycling fund system. In order to develop the recycling fund system, a system dynamic model was proposed and simulated to optimize the recycling funds and subsidies based on decentralized reverse supply chains. Although it is not a novelty model; however, the research show a very significant results for the government in Indonesia. This enabled a more precise, well-planned, and sustainable decision-making process for the EPR. In addition, by utilizing the system dynamic model with different scenarios in a real case study (aseptic paper packaging waste), we found that the capacity of the recycler could become the reference for the funds to be paid by the importer-producer group, wherein the recycling rate will increase with an increase in the recycling fund. • When formulating an EPR scheme, two points must be considered: framework and policies. • A system dynamic model was proposed and simulated to get the optimal solution. • A related case study involving aseptic paper packaging (APP) was considered.

Indonesia's internationally- and domestically-significant pulp and paper industries source their feedstock from tree plantations. A suite of regulatory (Indonesian Sustainable Production Forest Management Certification and Timber Legality Verification) and market instruments (forest certification) have been introduced to promote sustainability and legality of production from tree plantations, and some producers have also adopted other voluntary sustainability measures. This study investigates sustainability and legality compliance by actors in an Indonesian pulp and paper value chain as a case study of environmental innovation. Results are based on primary fieldwork along segments of the value chain, and analysis of audit reports and other publicly-available information. The value chain sources fibrewood from tree plantation concessions and pallet wood from a variety of suppliers. Audit reports suggest high levels of compliance with sustainability and legality requirements, but our research suggests that these reports might not reflect some area of poor performance and non-compliance. We identify weaknesses in the design of regulatory systems, and in auditing and monitoring processes, as the principal reasons for these deficiencies. Drawing on relevant theory and on practice elsewhere, we suggest that compliance and sustainability can be improved by addressing key areas of regulatory silence, by shifting auditing to be more performance-than paper-based, by strengthening independent monitoring from civil society, by increasing the frequency of witness auditing from the National Accreditation Board, and by fostering synergies between regulatory instruments and voluntary forest certification. These changes would improve the effectiveness of regulatory and voluntary instruments to promote cleaner production in Indonesian pulp and paper value chains. Image 1 • Indonesian pulp and paper value chains are globally significant. • These value chains must comply with national sustainability certification and legality verification systems. • Audit reports suggesting high levels of compliance do not appear to reflect areas of poor performance and non-compliance. • Weaknesses in regulatory design, auditing and monitoring are the main reasons for poor performance and non-compliance. • Changes in regulatory design and implementation would promote cleaner production in Indonesian pulp and paper value chains.

Dluwang was made from the bark of the paper mulberry ( Broussonetia papyrifera Vent.). Old Javanese manuscripts were handwritten on dluwang . Fungi samples from deteriorated dluwang manuscripts from the libraries of royal palaces in Indonesia and from the faculty library of Universitas Indonesia were collected by using cotton swabs and adhesive tape. Fungal isolates were obtained by the culture-dependent method. Identification of 38 fungal isolates was carried out by the molecular method using the internal transcribed spacer (ITS) regions of ribosomal DNA. Phenotypic description of the isolates was obtained by classic culturing and direct microscopic observation. The results showed that fungi from the genera of Aspergillus and Penicillium were commonly found on old dluwang manuscripts. According to the molecular identification, species obtained were Aspergillus awamori , Aspergillus clavatus , Aspergillus flavus , Aspergillus fumigatus , Aspergillus jensenii , Aspergillus niger , Aspergillus pulvericola , Aspergillus ruber ( Eurotium rubrum ), Aspergillus versicolor , Penicillium citrinum , Penicillium oxalicum , Penicillium rubens , Pseudocercospora chiangmaiensis , and Trichoderma longibrachiatum . The isolated fungi were xerophilic and cellulolytic in nature. All isolates were able to grow on dluwang paper, 29 isolates (76%) were able to utilize carboxymethyl cellulose (CMC), and 18 isolates (47%) were able to utilize CMC and microcrystalline cellulose (MCC). The present study showed that the deterioration of the written heritage was potentially caused by diverse fungi. [ABSTRACT FROM AUTHOR]

Summary: Qualitative and quantitative methods are applied to assess the impact of CIFOR’s political economy research on the Indonesian pulp and paper sector. Key-informant interviews triangulated by trend-series tests suggest important influence through advocacy intermediaries and counterfactuals of slower adoption of improvements. Effects on conservation set-asides, overcapacity, and plantation establishment are estimated to avert loss of 76,000–212,000hectares of natural forest (135,000 under main assumptions). Application of an economic-surplus framework for environmental benefits of forest conservation and avoided implicit wood subsidies finds benefits of US$19 to US$583 million (US$133 million main estimate), compared with US$500,000 of direct research costs.

Senior Citizen is an elderly human in a golden age who has many limitations. The number of older people is increasing in almost every country, including in Indonesia. One of the diseases that were suffered is senile or known as Dementia. Therefore, to protect the elderly, the special care is needed in order to be able to monitor the located and to see the condition of the elderly when they are travelling outside the home. Based on that condition, a prototype of the detector is proposed in this paper namely Smart tracking for the Golden Age's Citizen. This system consists of a GPS module, a vibration sensor, a GSM Module, and a voice recorder module. GPS module will detect the location, and the vibration sensor will detect the vibration if the elderly falls. The GSM module will send the information in the form of SMS to the family. The voice recorder module is used to record and play the recorded sound. Based on the results of the prototype test, the prototype is successfully detecting the location if the elderly is outside the range. The testing was concluding that the older people position can be tracked approximately around 2-5 meters from the determination in google map application and send an SMS in 3-5 seconds, if the user falls or lost.

Along with the popularity of the environment, social and governance (ESG) concerns, the circular economy concept has gained tremendous attraction from the industries, policy makers and academicians. On a firm level, this is implemented through the so-called Circular Business Model (CBM), which is seen through various initiatives. This includes firms in the energy industry, who are transitioning from conventional to renewable energy sources. Nevertheless, despite of the importance and the omnipresence of the practice, there is still lack of empirical research within the CBM topic. In particular, empirical research combining the CBM and technological innovation topic within energy industry (as technology-intensive and high risk industry) in developing country such as Indonesia, is still lacking. To answer this gap, using literature review as research method, this paper has arrived into the following propositions as main result; (1) there is a positive relationship between firm's level of CBM and technology innovation adoption to firm's performance, where (2) the two antecedents that are positively impacting firm's level of CBM and technology innovation adoption are leader's innovativeness and perceived level of technology. For academicians, this research is expected to provide contribution to the energy transition literatures within CBM and technology innovation adoption topic. Propositions provided in this paper is expected to serve as valuable basis in conducting further empirical research. For practitioners, this research is expected to provide valuable insights to make improvements and/or innovations in terms of business model, technology adoption, and strategy. At last, this research is expected to support energy transition. [ABSTRACT FROM AUTHOR]

COVID-19 was declared a world pandemic in early-mid 2020. After about a year, several vaccines for this virus have been found and become alternative solutions to reduce the spread of the COVID-19 pandemic and build up herd immunity in society. Since early 2021, Indonesia has been one of the countries that participate in using vaccines for the public to fight the COVID-19 pandemic. However, there are a lot of positive and negative responses from Indonesian society related to these COVID-19 vaccines. Implementing a sentiment analysis model for a specific topic like a "vaccine" from social media could help us to see and understand the responses from society in Indonesia towards the vaccine program that is being conducted by the Indonesian government. Understanding society's response towards vaccines is expected to be able to support the Indonesian government, for example in formalizing the distribution strategy of vaccines in the future. This paper discusses how to develop a sentiment analysis model, by implementing several existing technologies such as Twitter API, TextBlob , and Googletrans Python libraries. The utilization of these existing technologies could show how a sentiment analysis model could be developed conveniently, for example in using cases to analyse Indonesian society's responses towards the COVID-19 vaccine program. Besides the solution design, this paper also shows a sample of data visualization of the sentiment analysis model in a meaningful infographics format. [ABSTRACT FROM AUTHOR]

This paper examines the responses of credit and business cycle to various policy actions of the Government of Indonesia during the COVID-19 crisis. Specifically, the paper addresses two key questions (1) How do the credit and business cycle behave during the COVID-19 crisis in Indonesia? (2) Do the central bank and government policy responses effectively stabilize the credit and business cycle? Using the concordance Index and DCC-GARCH methodology, we found that the COVID-19 crisis increased Indonesia's credit and business cycle co-movements. Similarly, using the mixed data sampling regression technique, our findings suggest fiscal policy measures and government support help the business cycle revival during the COVID-19 pandemic. However, the monetary policy transmission is weak during the pandemic [ABSTRACT FROM AUTHOR]

In developing countries like Indonesia, adding a new unit for hydroprocessing facilities is more efficient than modifying the existing equipment. When the addition occurs, refiners should analyze if the existing hydrogen network can supply enough hydrogen to the new unit before constructing a costly hydrogen plant. Current studies on the hydrogen network have yet to consider pressure drop adequately. Therefore, this paper integrates pressure drop estimation and density prediction into the multi-objective MINLP-based hydrogen network. The multi-objective problem is solved sequentially by adding a minor unit to obtain each configuration's maximum flowrate and total annual cost. The optimal configuration based on the combined objective function is to add 1 PSA and compressor for a hydrogen purity of 0.84 and specified pressure requirements. The pressure drop integration shows an insignificant impact averaging 0.004 m3/s of maximum flowrate difference compared to optimization without pressure drop. • The addition of a new hydroprocessing unit is more efficient than existing refiners. • Multi-objective MINLP-based hydrogen network is used to analyze retrofit options. • The pressure drop integration shows a small impact on the overall. • Network. • The optimal configuration is to add one PSA and one compressor.

The prevalence of diabetes mellitus has increased over time. Medicinal plants, including Andrographis paniculata (Burm.f) Nees, are recognized for their use to manage hyperglycemia. Nowadays, plenty of papers are published about A. paniculata as an antidiabetic; however, no bibliometric study about the topic exists. This study examines the existing papers about the preclinical trial of A. paniculata as an antidiabetic agent using bibliometric analysis focusing on countries, institutions, publishers, authors, documents, and keywords. Bibliographic information of relevant research and conference articles were obtained from the Scopus database. In total, 97 articles published between 1994 and 2021 were selected, covering 376 authors and 1270 keywords. Data were analyzed bibliometrically using Vosviewer 1.6.16. A total of 97 published papers occurred from 1994 to 2021 were selected. India, Universitas Gadjah Mada (Indonesia), Journal of Ethnopharmacology, and Agung Endro Nugroho (Universitas Gadjah Mada, Indonesia) were the most productive country, institution, publisher, and author, respectively. The analysis of the most influential papers, co-citation network of the most influential papers, bibliographical coupling network based on authors, and keyword co-occurrence network and overlay demonstrated that the abundance and variety of existing papers about preclinical trials of A. paniculata as an antidiabetic were from phytochemistry, pharmacology, and drug formulation. The findings of our analysis have implications for managerial and theoretical aspects on this topic, such as encouraging research collaborations by analyzing the contributions of countries, institutions, publishers, and authors and revealing research gaps (molecular mechanisms, toxicities and side effects, drug formulations, and clinical trials) to accept a phytomedicine as a therapeutic option.

Higher education institutions in Indonesia are required to report their academic data to the national higher institution database (namely PDDikti) through a synchronization mechanism. Because the PDDikti database has been used as the reference for nationwide programs such as university ranking, diploma verification, faculty promotion, and tenure, academic data in their reports have to be valid, accurate, and up to date. Yet, data quality is an issue among higher institutions, while data governance is the heart of data quality. This paper investigates challenges encountered by a public university in Indonesia in implementing data governance and how to resolve them. The findings outline six main challenges in data governance implementation. [ABSTRACT FROM AUTHOR]

This study aims to predict the determinants of mobile fintech apps and digital financial inclusion from the perspective of the Bottom of the Pyramid (BOP) segment in Indonesia. To address the complexities of BOP users, this paper theoretically grounded on Mobile Technology Acceptance Model (MTAM) (i.e. mobile usefulness (MU), mobile ease of use (MEU)) along with its relevant extension including personal factor (digital financial literacy (DFL)), financial risk factor (mobile perceived financial cost (MPFC)), and consequent factors (i.e. use behavior (UB), and digital financial inclusion (DFI)). The moderating impact of gender was also tested. A survey instrument that was self-administered and comprised measurement items adapted from prior research was utilized to gather data from 200 mobile fintech BOP users residing in Makassar, South Sulawesi. According to the results of the PLS-SEM test, seven hypotheses were accepted, while two were rejected. In addition, it was confirmed that men play a more prominent role than women in strengthening mobile fintech use and digital financial inclusion. [ABSTRACT FROM AUTHOR]

Temporary trade barriers, such as safeguards, is a measure to rescue the economy in such a way as to protect domestic industries from foreign competitors. Safeguards provide opportunities for domestic industries to make structural adjustments and reshape their business process to increase their competitiveness during the validity period. Indonesia's government has imposed safeguards for most textile sub-industries, from the upstream industry (yarn and fibres) to the downstream garment industry and other related textile industries. This paper aims to evaluate whether the application of safeguards meets its objectives in improving the competitiveness of domestic industry against its foreign competitors with a long observation period. It is found that the effectiveness of the application of safeguards was limited to rescuing the trade balance. In terms of export competitiveness, safeguards have not been effective in increasing the export competitiveness of the textile industry in the world market. [ABSTRACT FROM AUTHOR]

Numerous research on stunting supplementation interventions in Indonesia have been published. The information can be extracted through data mining, especially from academic research databases. In this paper, we presented a text mining-based literature review strategy to create a pipeline that researchers can use to accelerate the development of stunting supplementation intervention research in Indonesia. Utilizing various NLP (Natural Language Processing) techniques, data were crawled, processed, and visualized using Python. The crawling dataset used a module from the Pubmed API (Application Programming Interface) to collect literature papers. The NLTK (Natural Language Toolkit) module and itertools were used to process text data. The n-grams model was applied to process tokens into bigrams and trigrams. Text information was visualized using Matplotlib and Word cloud packages. There is an increasing number of publication in stunting supplementation intervention according to our result, which was observed from 2015 to 2021. West Java was the province where most of the stunting research has been conducted, as determined by research abstracts. Top occurrences obtained from the bigram and trigrams models calculation produced different terms. The word pairings that occurred the most frequently in the bigram and trigram model analyses were "child-aged" and "iron-folic-acid," respectively. The findings of this study are expected to help researchers to obtain the latest research topics related to stunting supplementation interventions in Indonesia. [ABSTRACT FROM AUTHOR]

This study explores the key determinants of Supply Chain 4.0 (SC4.0) maturity in the context of a developing country by examining the relationships between supply chain ambidexterity, supply chain agility, and the maturity of SC4.0. The study was carried out using the survey method involving 154 managers from Indonesian manufacturing companies. The SC4.0 maturity model was developed and tested using structural equation modeling. From our analysis, it was found that supply chain ambidexterity emphasizing on innovation positively influences the companies' agility and SC4.0 maturity levels, and supply chain agility partially mediates supply chain ambidexterity. This paper contributes to the operationalization of SC4.0 maturity determinants that incorporate innovation and technological aspects and extends the extant literature by empirically elaborating the determinants and antecedents of SC4.0 maturity that may expedite the achievement of SC4.0 maturity. This implies that companies and supply chain professionals aiming at achieving their SC4.0 maturity should do so by being outward-looking and, at the same time, foster supply chain collaboration with external networks. This paper is pioneering the empirical study on SC4.0 and offers a means to achieving SC4.0 maturity through SC ambidexterity and SC agility, particularly in the context of a developing country.
