Authors: Arief R W , Mustikawati D R , Asnawi R 
Published: May 2023

Abstract
Pepper is a type of spice plant in Indonesia that used for cooking spices. One of the advantages of this spice is that it has a spicy taste and distinctive scent caused by piperine and essential oils contained in pepper seeds. This research was carried out from June 2018 to October 2019, using the main raw material for the Natar 1 variety of pepper. The pepper seed was processed into black pepper and white pepper, and the yield was calculated. Then observed levels of piperine and essential oils of black pepper and white pepper prior to and a year after storage. The data obtained were processed in a qualitative descriptive manner. The results showed that after 12 months of storage, there was a decrease in piperine content of 9.91% and a decrease in essential oil content of 21.77%; while white pepper decreased piperine content by 19.45% and essential oil content decreased by 56.91%. Based on the results of this study, good storage technology is needed to support the sustainability of the availability of black pepper and white pepper in particular, as well as pepper farming in general.

Abstract
Nanoemulsions are gaining considerable interest for use in delivery of essential oil-based pesticides. Evaluation in the laboratory have shown promising efficacy of nanobiopesticides, and further development in nanoemulsion production at larger scale is needed for a wider application in the field. This study aimed to evaluate the changes in droplet size characteristics of citronella oil nanoemulsions produced using spontaneous emulsification at increased scales. The preparation of nanoemulsion was carried out in two stages of scale-up, namely the laboratory scale (200–1000 mL) and the larger scale (10–50 L). The process variables included stirring speed and time. Characterization was done on the oil droplet size, polydispersity index (PDI), zeta potential and microscopic structure. The oil droplet size, PDi and zeta potential varied with the emulsification process conditions and the production scale. In general, increasing mixing speed and time tended to decrease droplet size and PDI, and increase zeta potential. The changes in characteristics of nanoemulsion were minor at the higher production scales. Relatively small droplet sizes were found in the whole experiment (90–160 nm) with PDI of 0.2 – 0.4 and zeta potential of -28 to -8.8 mV. These results are useful for the design of nanoemulsion production at practical application scale.

Abstract
The Indonesian government developed environmentally electrical power, such as a Bakaru hydroelectric power plant (Bakaru PLTA). The Bakaru PLTA is located in the Mamasa sub-watershed. Some parts of the Mamasa sub-watershed are managed by three Forest Management Units (FMU): Mamasa Tengah FMU, Mamasa Timur FMU, and Sawitto FMU. Previous studies indicated that land-use change was a driving factor in decreasing water discharge and increasing sedimentation. Therefore, it is crucial to discover the role and influence of FMU conditions on the performance of the Bakaru PLTA. This study aims to determine Mamasa sub-watershed conditions, especially FMUs areas, to see the contribution and strategies that FMUs can carry out to support the energy production of the PLTA Bakaru. This research used the literature study method and overlaid several maps. The study showed that FMUs faced erosion, sedimentation, and degraded land, influencing Bakaru PLTA performance. The study recommends that rehabilitation be prioritized on the degraded and very degraded land categories at 27 villages in Mamasa Timur FMU, 18 villages in Mamasa Tengah FMU, and eight villages in Sawitto FMU.
The Deconstruction of Policy on Coal Waste: Threats and Challenges in Achieving Ecological Justice

Abstract
The coal mining sector is one of the national streams subjected to non-tax revenues. It requires efficient managerial models including economic growth, social, and environmental sustainability. The issuance of Government Regulation Number (GRN) 22/2021 as a derivative of the Job Creation brings about pros and cons between entrepreneurs and environmentalists. Coal waste is not a subject of criminal offense because it is not classified as hazardous (B3). Therefore, this study aimed to evaluate the regulation and execution of the coal waste policy. Data were analyzed using normative with three approaches including legislation, conceptual, and case. The results indicated that the exception of coal waste from B3 affects responsibility and becomes profitable only for entrepreneurs. Coal waste was removed from B3 due to its potential as innovative fuel. The GRN 22/2021 failed to provide apparent legitimacy for entrepreneurs to manage the waste. This policy became a setback in the country’s commitment to realizing sustainable development since it is contrary to UN resolution 66/288.

Abstract
The legal policy of protection of customary or ulayat rights in Kampar Regency has been regulated in Kampar Regency Regional Regulation (Perda) Number 12 of 1999 concerning Ulayat Land Rights. It’s just that the implementation of the legal policy in question has not been optimal so it has not been effective enough in solving all ulayat rights problems in Kampar Regency. This article explained the content of the legal policy on the protection of ulayat rights in Kampar Regency. Then analyze the effectiveness of the implementation of these legal policies in solving ulayat rights problems. The method used is normative legal research with a conceptual and statute approach supplemented by interviews, as well as qualitative-deductive analysis. This paper recommends that the legal policy of protection of customary rights in Kampar Regency be improved in accordance with the development of laws or regulations and the condition of indigenous peoples so that it is expected to function effectively in providing ulayat rights protection for indigenous peoples in Kampar Regency.
Indonesia’s Plan for Concurrent Regional Expansion
Authors: Indra M 
Published: May 2023

Abstract
The development of ties between the center and the regions came to light after Indonesia underwent reformation in 1998. A new paradigm in the management of local government in Indonesia has emerged as a result of the passing of Law No. 22 of 1999. One effect of the passage of Law No. 22 of 1999 was the enlargement of the region to create a number of new autonomous regions. The pattern of creating new autonomous areas based on the will of the people causes certain regional expansions to be successful while others result in conflicts due to the interests of local elites (bottom-up). Therefore, the creation of new autonomous zones and the birth of a new paradigm require a new formulation. As a result, the creation of new autonomous regions requires a new formulation, and Law No. 23 of 2014’s regional structuring idea represents the development of a new paradigm. How to formulate the development of a new autonomous region through concurrent regional expansion is the study’s formulation of the problem. According to the study’s findings, regional growth is required in order to meet the needs of the envisioned increase in the number of Provinces, Regencies, and Cities.
Effect of tempering temperature and subzero treatment on microstructures, retained austenite, and hardness of AISI D2 tool steel
Authors: Mochtar Myrna Ariati , Putra Wahyuaji Narottama , Abram Martin 
Published: May 2023

Abstract
The presence of retained austenite in the hardening process of tool steel often causes the lower hardness compared to the hardness requirements and poor dimensional stability in the tool steel. The purpose of the present research is to determine the relationships between the tempering process with and without cryogenic treatment to the hardness and retained austenite amount of as-hardened D2 tool steel. The austenitizing temperature was 1020 °C, the tempering temperatures have variations of 180 °C, 280 °C, 380 °C, 480 °C, and 580 °C, and the subzero treatment has a temperature of −172 °C, followed by tempering at 180 °C, 380 °C, and 580 °C. This study aims to determine the appropriate treatment to obtain a minimum retained austenite percentage to prevent and mitigate the failure of AISI D2 tool steel in the industrial application process. An optical microscope with image processing software (Image-J analysis), as well as Brinell and Vickers hardness testing, is the characterization method used in this work. In general, plate martensite, bainite, retained austenite, and primary and secondary carbides are the phases contained in the microstructure. Tempering temperatures have the effect of increasing the secondary carbide precipitation and decreasing the retained austenite content (γr 3,671%–2,769%). However, the cryogenic treatment can provide a more efficient martensitic phase transformation process and minimal retained austenite content (γr 2,257%–1,199%). The increase in tempering temperature causes a decrease in hardness at a temperature of 180 °C–380 °C. On the other hand, the secondary hardening and phase transformation phenomena cause an increase in the hardness of the as-tempered sample at a temperature of 480 °C, before the sample reexperiences a significant decrease in hardness at a temperature of 580 °C due to diffusion that decreases the carbon content.

Abstract
Despite the occurrence of wildfires quadrupling over the past four decades, the health effects associated with wildfire smoke exposures during pregnancy remains unknown. Particulate matter less than 2.5 μms (PM2.5) is among the major pollutants emitted in wildfire smoke. Previous studies found PM2.5 associated with lower birthweight, however, the relationship between wildfire-specific PM2.5 and birthweight is uncertain. Our study of 7923 singleton births in San Francisco between January 1, 2017 and March 12, 2020 examines associations between wildfire smoke exposure during pregnancy and birthweight. We linked daily estimates of wildfire-specific PM2.5 to maternal residence at the ZIP code level. We used linear and log-binomial regression to examine the relationship between wildfire smoke exposure by trimester and birthweight and adjusted for gestational age, maternal age, race/ethnicity, and educational attainment. We stratified by infant sex to examine potential effect modification. Exposure to wildfire-specific PM2.5 during the second trimester of pregnancy was positively associated with increased risk of large for gestational age (OR = 1.13; 95% CI: 1.03, 1.24), as was the number of days of wildfire-specific PM2.5 above 5 μg m−3 in the second trimester (OR = 1.03; 95% CI: 1.01, 1.06). We found consistent results with wildfire smoke exposure in the second trimester and increased continuous birthweight-for-gestational age z-score. Differences by infant sex were not consistent. Counter to our hypothesis, results suggest that wildfire smoke exposures are associated with increased risk for higher birthweight. We observed strongest associations during the second trimester. These investigations should be expanded to other populations exposed to wildfire smoke and aim to identify vulnerable communities. Additional research is needed to clarify the biological mechanisms in this relationship between wildfire smoke exposure and adverse birth outcomes.

Abstract

Background
previous studies have focused on the risk of cardiovascular disease (CVD)-related death in individual cancers, adolescents or all cancers.

Objective
to evaluate the risk of CVD-related death in older patients with cancer.

Methods
older patients with cancer (over 65 years) of 16 cancers diagnosed between 1975 and 2018 were screened out from the Surveillance, Epidemiology and End Results program. The proportion of deaths, competing risk regression models, standardized mortality ratios (SMRs) and absolute excess risks (AERs) were used to assess the risk of CVD-related death.

Results
this study included 1,141,675 older patients (median follow-up: 13.5 years). Of the 16 individual cancers, the risk of CVD death exceeded primary neoplasm death in older patients with cancers of the breast, endometrium, vulva, prostate gland, penis and melanoma of the skin over time (high competing risk group). Compared to the general older population, older patients with cancer had higher SMR and AER of CVD-related death (SMR: 1.58–4.23; AER: 21.16–365.89), heart disease-related death (SMR: 1.14–4.16; AER: 16.29–301.68) and cerebrovascular disease-related death (SMR: 1.11–4.66; AER: 3.02–72.43), with the SMR trend varying with CVD-related death competing risk classifications. The risk of CVD-related death in the high-competing risk group was higher than in the low-competing risk group.

Conclusions
for older patients with cancer, six of 16 individual cancers, including breast, endometrium, vulva, prostate gland, penis and melanoma of the skin was at high risk of CVD-related death. Management for long-term cardiovascular risk in older patients with cancer is needed.

Published: May 2023

Abstract
We sought to assess the relationship between sleep duration, sleep disturbance, and leukemia incidence among postmenopausal women. This study included 130,343 postmenopausal women aged 50–79 years who were enrolled in the Women’s Health Initiative (WHI) during 1993–1998. Information on self-reported typical sleep duration and sleep disturbance was obtained by questionnaire at baseline, and sleep disturbance level was defined according to the Women’s Health Initiative Insomnia Rating Scale (WHIIRS). WHIIRS scores of 0–4, 5–8, and 9–20 comprised 37.0%, 32.6%, and 30.4% of all women, respectively. After an average of 16.4 years (2,135,109 cumulative person-years) of follow-up, 930 of the participants were identified as having incident leukemia. Compared with women with the lowest level of sleep disturbance (WHIIRS score 0–4), women with higher sleep disturbance levels (WHIIRS scores of 5–8 and 9–20) had 22% (95% confidence interval (CI): 1.04, 1.43) and 18% (95% CI: 1.00, 1.40) excess risks of leukemia, respectively, after multivariable adjustment. A significant dose-response trend was found for the association between sleep disturbance and leukemia risk (P for trend = 0.048). In addition, women with the highest level of sleep disturbance had a higher risk of myeloid leukemia (for WHIIRS score 9–20 vs. WHIIRS score 0–4, hazard ratio = 1.39, CI: 1.05, 1.83). Higher sleep disturbance level was associated with increased risk of leukemia, especially for myeloid leukemia among postmenopausal women.
Impulse control disorder in Parkinson’s disease is associated with abnormal frontal value signalling

Published: May 2023

Abstract
Dopaminergic medication is well established to boost reward- versus punishment-based learning in Parkinson’s disease. However, there is tremendous variability in dopaminergic medication effects across different individuals, with some patients exhibiting much greater cognitive sensitivity to medication than others. We aimed to unravel the mechanisms underlying this individual variability in a large heterogeneous sample of early-stage patients with Parkinson’s disease as a function of comorbid neuropsychiatric symptomatology, in particular impulse control disorders and depression.
One hundred and ninety-nine patients with Parkinson’s disease (138 ON medication and 61 OFF medication) and 59 healthy controls were scanned with functional MRI while they performed an established probabilistic instrumental learning task. Reinforcement learning model-based analyses revealed medication group differences in learning from gains versus losses, but only in patients with impulse control disorders. Furthermore, expected-value related brain signalling in the ventromedial prefrontal cortex was increased in patients with impulse control disorders ON medication compared with those OFF medication, while striatal reward prediction error signalling remained unaltered.
These data substantiate the hypothesis that dopamine’s effects on reinforcement learning in Parkinson’s disease vary with individual differences in comorbid impulse control disorder and suggest they reflect deficient computation of value in medial frontal cortex, rather than deficient reward prediction error signalling in striatum.

Authors: Heikkala Eveliina , Oura Petteri , Ruokolainen Olli , Ala-Mursula Leena , Linton Steven J , Karppinen Jaro 
Published: May 2023

Abstract

Background
The Örebro Musculoskeletal Pain Screening Questionnaire (ÖMPSQ) was developed to identify psychological and functioning-related risk factors among individuals with musculoskeletal pain at risk of work disability. This study aimed to examine whether the short version of the ÖMPSQ (ÖMPSQ-SF) can be used for this purpose, using registry-based outcomes.

Methods
The ÖMPSQ-SF was completed by the members of the Northern Finland Birth Cohort 1966 at the age of 46 years (baseline). These data were enriched with national registers, including information on sick leaves and disability pensions (indicators of work disability). The associations between the ÖMPSQ-SF categories (low-, medium- and high risk) and work disability over a 2-year follow-up were analysed using negative binomial regression and binary logistic regression models. We made adjustments for sex, baseline education level, weight status and smoking.

Results
Overall, 4063 participants provided full data. Of these, 90% belonged to the low-risk, 7% to the medium-risk and 3% to the high-risk group. Compared to the low-risk group, the high-risk group had a 7.5 [Wald 95% confidence interval (CI) 6.2–9.0] times higher number of sick leave days and 16.1 (95% CI 7.1–36.8) times higher odds of disability pension after adjustments in the 2-year follow-up.

Conclusions
: Our study suggests that the ÖMPSQ-SF could be used for predicting registry-based work disability at midlife. Those allocated to the high-risk group seemed to have a particularly great need of early interventions to support their work ability.
“It’s Just [Complicated] Sleep”: Discourses of Sleep and Aging in the Media
Authors: Breheny Mary , Ross Isabelle , Ladyman Clare , Signal Leigh , Dew Kevin , Gibson Rosemary 
Published: May 2023

Abstract
The media are influential in shaping beliefs and attitudes on aging and health-related behaviors. Sleep is increasingly recognized as a key pillar for healthy aging. However, the role of media representations of sleep is yet to be assessed with regard to discourses of aging. Texts from New Zealand’s main free online news source were collated using key words “sleep” together with “aging,” “older,” “elderly,” or “dementia” between 2018 and 2021. Contents of 38 articles were interpreted using critical discourse analysis. Discursive constructions described an inevitable decline of sleep with aging, including impacts of both physiological decline and life stage transitions; sleep’s role as both a remedy and risk for ill health and disease; and the simplification of solutions for self-managing sleep juxtaposed alongside recognition of its complexity. The audience of these complex messages is left in the invidious position of both pursuing sleep practices to prevent age-related decline, whilst also being told that sleep degradation is inevitable. This research demonstrates the complexity of media messaging and the fraught options it offers: good sleep as both a reasonable achievement to strive for and as impossibly idealistic. Findings mirror two predominant health identities available to older people, as responsible for resisting aging or as falling into inevitable decline. This reveals additional expectations around appropriate time use and behaviors with aging. More nuanced messaging that goes beyond sleep as a resource for health and waking productivity is recommended. Acknowledging the complexity of sleep, aging, and society could be the starting point of such adaptation.
Mind the time: failure response time, variations in the reasons for failures, and learning from failure
Authors: Zakaryan Arusyak , Tzabbar Daniel , Cirillo Bruno 
Published: May 2023

Abstract
How does a firm’s response time to past failures affect its likelihood of experiencing future failures? Does this likelihood depend on the reasons for past failures? Using drug recalls during 2006–2016, we examine the effect of pharmaceutical firms’ response time to their past failures on their learning from failure. Longer response times reduce the likelihood of subsequent failure. Variations in the reasons for past failures increase the potential for subsequent failure. However, a longer response time helps overcome the challenges associated with this variation. By focusing on the temporal dimension of learning from failure, we provide unique theoretical insights into when and how organizations can learn from failure.
Adaptive stabilization for a wave equation subject to boundary control matched harmonic disturbance
Authors: Liu Jun-Jun , Zhao Yan-Xing 
Published: May 2023

Abstract
In this paper, we are concerned with adaptive stabilization for a wave equation subject to boundary control matched harmonic disturbance. We use the adaptive and Lyapunov approach to estimate unknown disturbance and construct an adaptive boundary feedback controller. By the semigroup theory and Lasalle‘s invariance theorem, the well-posedness and asymptotic stability of the closed-loop system is proved, respectively. At the same time, it is shown that the parameter estimates involved in the constructed controller converge to their own real values as time goes to infinity. Some numerical simulations are offered at the end of the paper to illustrate the effectiveness of theoretical results.
