Гострий інфаркт міокарду (ГІМ) є однією з провідних причин смертності дорослого населення в Україні та світі серед усіх серцево-судинних за- хворювань. Дуже часто ГІМ виникає у пацієнтів з різноманітними коморбідними станами. Саме цукровий діабет 2 типу (ЦД 2 типу) є частим супутнім захворюванням пацієнтів з ГІМ. З метою зменшення проявів оксидативного стресу у пацієнтів з такою коморбідністю вико- ристовується кардіопротективна терапія. Найпоширенішими сполуками, які застосовуються з кардіопротективною метою є молекули кверцетину і аденозину. Метою дослідження є підвищення ефективності лікування пацієнтів з ГІМ в поєднанні із цукровим діабетом 2 типу шляхом кардіо- протекції з використанням кверцитину та аденозинвмісного препарату адвокард. У дослідження включено 60 пацієнтів із ГІМ та ЦД 2 типу. Пацієнти були розділені на 2 групи: контрольна група отримувала базову терапію ГІМ та ЦД 2 типу. Пацієнтам основної групи додатково до базової терапії призначався кверцетин (4,5 г внутрішньовенно впродовж 5 днів) та адвокард за схемою. В ході дослідження ми досліджували ехокардіографічні показники. За даними нашого дослідження, застосування кверцитину та аденозвмісного препарату авдокард веде до покращення систолічної функції лівого шлуночка, сприяє зворотньому ремоделюванню лівого шлуночка.

The article presents the results of studies of the impact response of ceramic-metal composites ZrO2/Ti and ZrO2/Al with non-rigid fixing of layers. It is shown that as the energy dissipates from layer to layer, there is an increase in the dispersion of the structure of metal foils and ceramic plates. ZrO2/Ti ceramic-metal composites have higher impact strength, and the impact strength of layered ZrO2/Al composites practically did not differ from the impact strength of monolithic ceramics. It was shown that regardless of the distance between the ceramic plates and the point of impact, their destruction occurred with the transformation of the ZrO2 tetragonal modification into a monoclinic one.

Authors: Patino-Galván Israel , Hernández Aguilar José Alberto
Published: April 2023

Antes de la pandemia el desarrollo económico de las Micro, Pequeñas y Medianas Empresas (MiPyME) en Latinoamérica presentaba indicios paulatinos de recuperación tras los problemas presentados en los años 2009 y 2016. México a partir del 2017 mantuvo una inflación creciente del 5% promedio, el precio de los energéticos aumentó en un 20%, el crecimiento de la deuda externa un 12% y el PIB fue menor al 1.6% anual (Banco Mundial, 2020), (OCDE, 2019), (INEGI, 2018). Para finales del 2019, el SARS-CoV-2 (COVID – 2019) evidenció factores de fracaso que agudizaron la permanencia de las MiPyME ya que cerraron más del 30.6% de ellas (Naciones Unidas, 2021). En esta investigación se discuten dichos factores, para ello, se recopiló información del comportamiento económico, y de estudios cuantitativos de los sectores comerciales, manufactura y servicios. Para identificar estos factores, se encuestaron a 246 MiPyME mexicanas que cerraron entre septiembre del 2019 y diciembre del 2020, las cuales fueron seleccionadas mediante muestreo aleatorio estratificado. Los resultados evidenciaron factores de fracaso asociados a las capacidades del administrador y a aspectos internos de la empresa, entre los que destacan la falta de visión para identificar nuevos negocios y poco conocimiento de las Tecnologías de la Información.
Handling Public Well-being During the COVID-19 Crisis: Empirical Study With Representatives From Municipalities in Sweden
Authors: Alaqra Ala Sarah , Khumalo Akhona C
Published: April 2023

Background

COVID-19 has had a significant impact on the public’s health and well-being due to infections and restrictions imposed during the crisis. Recreational activities are important for the public’s well-being; however, the public’s safety from the COVID-19 virus is the top priority. Sweden, a country with a decentralized public health and welfare system, relied on less stringent approaches for handling the crisis. The limited restrictions in Sweden allowed recreational activities to take place despite the pandemic, which could be attributed to considerations for the public’s well-being.

Objective

The objective of this study was to investigate municipal approaches for handling and supporting recreational activities during the COVID-19 crisis.

Methods

We conducted an empirical study (qualitative and quantitative), using an online survey for data collection, with 23 participants. They were representatives holding mostly managerial roles in 18 distinct municipalities (18 counties). A thematic analysis was conducted to analyze open-ended responses, and descriptive statistics were used to summarize the closed-ended responses.

Results

In this study, we report on the status of municipalities during the COVID-19 pandemic. The highlighted results showed a significant impact on the municipalities as a result of COVID-19, where 78% (18/23) of participants stated significant changes due to the pandemic. Moreover, 91% (21/23) indicated efforts and approaches for supporting recreational activities during COVID-19. Following national guidelines for the public’s health and safety was indicated by 78% (18/23) of participants. Information and communications technology (ICT) was considered significant for dealing with COVID-19 according to 87% (20/23) of participants. Our qualitative results further showed details of the public’s health and safety considerations, the efforts to support recreational activities particularly for youth, and the role and requirements of ICT. Challenges relating to the usability of ICT were also highlighted.

Conclusions

Despite the critique of Sweden’s lenient strategy for handling the COVID-19 crisis, our results showed significant considerations for the public’s safety and well-being by the municipalities (regional and local levels) in this study. The Swedish approach to handling the crisis involved trusting the public with safety guidelines in addition to efforts for the public’s safety, supporting the public’s well-being with approaches for maintaining recreational activities, and giving special care to the youth. Despite having technological solutions in place, challenges in using digital solutions and requirements for future development were noted.

Authors: Rao Kaushal , Speier William , Meng Yiwen , Wang Jinhan , Ramesh Nidhi , Xie Fenglong , Su Yujie , Nowell W Benjamin , Curtis Jeffrey R , Arnold Corey
Published: April 2023

Background

The increasing use of activity trackers in mobile health studies to passively collect physical data has shown promise in lessening participation burden to provide actively contributed patient-reported outcome (PRO) information.

Objective

The aim of this study was to develop machine learning models to classify and predict PRO scores using Fitbit data from a cohort of patients with rheumatoid arthritis.

Methods

Two different models were built to classify PRO scores: a random forest classifier model that treated each week of observations independently when making weekly predictions of PRO scores, and a hidden Markov model that additionally took correlations between successive weeks into account. Analyses compared model evaluation metrics for (1) a binary task of distinguishing a normal PRO score from a severe PRO score and (2) a multiclass task of classifying a PRO score state for a given week.

Results

For both the binary and multiclass tasks, the hidden Markov model significantly (P<.05) outperformed the random forest model for all PRO scores, and the highest area under the curve, Pearson correlation coefficient, and Cohen κ coefficient were 0.750, 0.479, and 0.471, respectively.

Conclusions

While further validation of our results and evaluation in a real-world setting remains, this study demonstrates the ability of physical activity tracker data to classify health status over time in patients with rheumatoid arthritis and enables the possibility of scheduling preventive clinical interventions as needed. If patient outcomes can be monitored in real time, there is potential to improve clinical care for patients with other chronic conditions.

Authors: Maikos Jason T , Hendershot Brad D , Pruziner Alison L , Hyre Michael  J , Chomack John M , Phillips Samuel L , Heckman Jeffrey T , Sidiropoulos Alexis N , Dearth Christopher L , Nelson Leif M
Published: April 2023

Background

The prescription of prosthetic ankle-foot devices is often based on the professional judgment of the limb loss care team or limited evidentiary research. Current prosthetic research efforts have focused on the design and development of prosthetic devices rather than on understanding which devices are the most appropriate to prescribe. This investigation will evaluate biomechanical, functional, and subjective outcome measures to help determine the optimal prescription parameters of prosthetic ankle-foot devices.

Objective

This study aims to develop evidence-based guidelines for limb loss care teams for the appropriate prescription of commercially available prosthetic ankle-foot devices to improve function and satisfaction.

Methods

This investigation will be a multisite, randomized, crossover clinical trial targeting the enrollment of 100 participants. Participants will use 3 different types of prosthetic devices (energy storing and returning, articulating, and powered) in random order. Participants will be fitted and trained with each device and then separately use each device for a 1-week acclimation period. Following each 1-week acclimation period, participants will be evaluated using several functional measures and subjective surveys. A random subset of participants (30/100, 30%) will also undergo full-body gait analysis, following each 1-week acclimation period, to collect biomechanical data during level ground and incline and decline walking. After all individual device evaluations, participants will be given all 3 prostheses concurrently for 4 weeks of home and community use to capture user preference. Activity monitoring and a guided interview will be used to determine overall user preference.

Results

The study was funded in August 2017, and data collection began in 2018. Data collection is expected to be completed before July 2023. Initial dissemination of results is expected to occur in the winter of 2023.

Conclusions

By identifying biomechanical, functional, and subjective outcomes that are sensitive to differences in prosthetic ankle-foot devices, a benchmark of evidence can be developed to guide effective prosthetic prescription.

How anthropological approach address social determinants of health in Asmat, Papua
Authors: Visnu Jodi
Published: April 2023

Indonesia faced one of the most tragic and challenging health problems at the beginning of 2018, many children in Papua's Asmat Regency were suffering from malnutrition and measles. More than a thousand children were treated while 78 children under five years of age have died, mostly indigenous children. Asmat Regency is located in Indonesia's easternmost province with poor infrastructure and communication networks, also high transportation costs due to swampy regions criss-crossed by rivers, hard-to-reach from the center to the districts. Asmat's belief in their ancestors has formed their way of life and shaped their behavior, choices, and attitudes towards health issues, such as poor awareness regarding the fulfillment of daily nutritional intake, which is potentially harmful. Curative care is the highest priority in an extraordinary incident such as an outbreak or a mass-casualty disaster. However, establishment of the cultural hegemony of biomedicine will not be achieved overnight. Changing people's health behavior is a significant challenge. To maintain health sustainability, we must reach the entire community, including rural and remote areas, and work together with local indigenous stakeholders to bridge the gaps in sociocultural understanding. Resources that enhance the quality of life can have a significant influence on population health outcomes. By applying what we know about the Social Determinants of Health (SDH), we may not only improve population health but also advance health equity. The author offers a participant observation, discussing the social determinants based on self-experience living in an indigenous community in Asmat. This article aims to provide an overview of SDH in Asmat through the approach of medical anthropology, as the SDH may potentially have roles in health outbreaks, especially in the case of malnutrition and measles in early 2018.

Despite the average life expectancy of Indonesian people increasing from 63.63 in 1990 to 71.69 in 2016, the gap of life expectancy and healthy age life expectancy also increased from 7.49 to 8.72. RISKESDAS (2018) further highlighted that the proportion of Indonesian people with a healthy diet was poor. These data challenged us to implement an outreach program, Community and Family Health Care – Interprofessional Education (CFHC-IPE), involving our medicine, nursing and nutrition students for assisting families and communities with an aim of improving the population health status. Thus, we assessed their baseline status, in particular, people’s dietary habits. We attached batch 2015 and 2016 students to 465 households with 1,254 family members. We deployed them to 15 different sub-villages in Sleman Regency, Yogyakarta. Students surveyed the families and put the data in family folders during field visits in 2018 – 2019. Our focus was to seek eating patterns of the families and performed descriptive analysis of socio-demographic aspects within those with certain dietary habits using chi-squared tests. Of the 1,254 family members, those who routinely consume fried, sweetened, contained preservatives and grilled foods were 70.14%, 61.00%, 38.13%, and 20.08%, respectively. We found the adults tend to consume more sweetened foods and beverages along with grilled foods compared to the elderly, and the differences of proportions are statistically significant. The CFHC-IPE program partner families were often not realizing that a combination of their dietary habits, in particular, the consumption of fried and sweetened meals might result in threats to the family members’ health. Fried foods were the most routinely consumed followed by sweetened food, grilled foods and foods containing preservatives. These patterns were also the same in both urban and rural settings.

Authors: Azimuddin Azmiera , Roslan Mohamad Farhan , Teguh Widodo Riyanto
Published: April 2023

Orally disintegrating tablets are a solid dosage form compromising medicinal substances which disintegrate rapidly, generally within a matter of seconds, when placed on the tongue. In this study, paracetamol orally disintegrating tablets was formulated and evaluated. Direct compression was used to prepare 350 mg tablets of five formulations (F1- F5) by using a single punch manual tableting machine. Pre-formulation studies were performed on the powder mixture of each formulation to obtain information regarding their flow properties. The tablets from each formulation were also evaluated for weight uniformity, drug content uniformity, thickness, hardness, friability, disintegration and dissolution. The disintegration tests carried out revealed that tablets from F2 showed the shortest disintegration time of 32.67 ± 3.14 seconds followed by tablets from F5, F3, F4 and F1. However, the dissolution results illustrated that tablets from F5 have the best dissolution profile, releasing 84.70 ± 5.31% of drugs within 4 minutes. Hence the most optimized formulation of a paracetamol orally disintegrating tablet in this study.
Element Recognition and Innovation Transformation of Cultural and Creative Products: Based on Eye Movement Experiment
Authors: Guo Wei , Wang Yangyang , Xu Tianjun
Published: April 2023

This paper analyzes tourists’ perceived preferences for cultural and creative product elements using human-computer interaction technology and constructs the innovation and transformation path of cultural and creative products from four dimensions: concept, elements, content, and structure. The Great Wall tourism cultural and creative products are used as an example. The findings demonstrate that: (1) From a behavioral data viewpoint, cultural and creative items’ overall inventiveness, formal design, manufacturing method, area, cultural collection value, and function have varying degrees of influence on visitors’ perceived preferences; (2) The richness and attraction of character expression, action, and form components from the hotspot map and matrix map can boost the visual engagement impact of visitors. Scenic area architecture may enhance visitors’ immersion experiences of local culture since it serves as the design prototype for cultural and creative businesses. (3) The number of fixation points, total fixation time, and saccade frequency of cultural and creative products with various design elements differ significantly when viewed from the perspective of the eye movement index, and these differences are further presented as individualized tourist behavior characteristics. (4) From a design standpoint, it is essential that the circumstances of the product satisfy the needs of visitors in order to produce high-quality cultural and creative products. Innovative ideas should be used to steer the innovation and transformation of cultural and creative products, enhancing the universal design of products with element innovation, enhancing the cultural legacies of products with content innovation, and lengthening the market cycle of products with structural innovation. The use of modern technology broadens the research methodologies for the tourism field and creates new research environments for tourism experimentation.

Published: April 2023

Drawing on conservation of resources theory and event system theory, we explored the relationship between empowering leadership and leaders' psychological well-being. Multiwave data were collected from 190 leaders in a variety of companies in Mainland China. We found that empowering
leadership was positively related to leader recovery, which mediated the positive effect of empowering leadership on leaders' psychological well-being. Event disruption moderated the positive relationship between empowering leadership and leader recovery, such that the relationship was significant
only when event disruption was low. Furthermore, event disruption moderated the indirect effect of empowering leadership on leaders' psychological well-being via leader recovery, such that the effect was significant only when event disruption was low. Implications and limitations of our study
are discussed.

Objectives The purpose of this study is to examine the differences among college students' flow, emotional clarity, and suicide risk variables according to the level of gambling addiction, and to verify the difference in influence between the variables according to the level of gambling addiction. Methods The To this end, after selecting 633 students from 7 universities located in Daegu, Gyeongbuk, and Busan, research analysis was conducted using F-test and multigroup analysis. Statistical significance was verified at a significance probability of .05. Results First, there were significant differences in flow, emotional clarity, and suicide risk of college students according to the level of gambling addiction. In other words, the pathological gambling group showed a higher flow state and suicide risk than the low-risk gambling group, and showed a lower emotional clarity. Second, in the verification of the difference in influence between flow, emotional clarity, and suicide risk, it was found that there was a significant difference according to the level of gambling addiction in all pathways. Conclusions It was found that the pathological gambling group showed a higher suicide risk based on a higher flow state than the low-risk gambling group, and showed a lower emotional clarity based on a higher flow state. The low-risk gambling group showed a lower suicide risk based on higher emotion clarity compared to the pathological gambling group. Therefore, it can be suggested that a program for emotional and behavioral control needs to be applied to a group with gambling addiction problems.

Objectives The purpose of this study was to develop and verify its validity the Career Barriers Inventory(CBI) of adolescents. Methods Based on the concept of contextual barriers in the selection model of social cognitive career theory(SCCT) devised by Lent et al. (1994), the concept of career barriers was established as a monistic point of view limited to environmental barriers. Based on this point of view, initial items were selected, from previous studies. After verifying the validity of the contents by related research experts, an item comprehension test was conducted on 10 middle and high school students, and a total of 27 scale items were developed. Data were collected from middle and high school students nationwide, and 128 of the preliminary survey and 236 of the main survey were used for tool development as valid data. Results Major findings of the study were as follows; The construct validity of the EFA conducted using the preliminary survey data was secured and a preliminary scale with a total of 27 items was developed. In addition, as a result of CFA using the data of this survey to determine the model suitability, the CBI model for adolescents with a total of 22 items of 4 factors finally satisfied all validation criteria. As a result of examining the correlation between the sub-factors of CBI and the sub-factors of self-esteem and social support, all of them were significant and the coccurrent validity was verified. Conclusions Based on the theoretical and empirical basis for the career barriers of monism, which were defined only for the internal and external barriers of SCCT, the sub-factors of career barriers for middle and high school students were identified, and a systematic validation process was performed to develop the CBI for adolescents and verify its validity.

The article analyzes the publications of three key Egyptian think tanks on the causes, consequences and global context of the Ukrainian crisis, as well as its impact on the Middle Eastern countries and Egypt’s position. The author examines the publications of think tanks that are able to influence foreign policy decisions in Egypt. In this way the author seeks to assess the potential for Egypt changing its position on the Russian SMO, as well as analyse the prevailing views on the impact of the Ukrainian crisis on international relations among the Egyptian expert community. In their publications, the Egyptian think tanks focus on the three key topics: the global context of the Ukrainian crisis and its consequences for the system of international relations, the impact of the Ukrainian crisis on the situation in the Middle East, and Egypt’s position on the Ukrainian crisis. Egyptian experts see the Ukrainian crisis as a manifestation of great-power competition and view it as a starting point for future changes in the world order. At the same time, they clearly see its negative consequences for the economic situation in the Middle Eastern countries and especially in Egypt, however, they highly value the neutral position taken by Cairo

Parakuat diklorida merupakan bahan aktif herbisida yang digunakan untuk membasmi gulma di perkebunan kelapa sawit. Penggunaan parakuat diklorida yang tidak sesuai dengan standar memungkinkan dapat meninggalkan residu pada minyak sawit (crude palm oil, CPO) sehingga kadarnya perlu ditentukan untuk keamanan produk pangan. Penelitian ini dilakukan untuk menentukan parakuat diklorida pada matriks minyak sawit dengan proses pemurnian (clean up) dan analisa menggunakan spektrofotometer UV-Vis. Proses clean up dilakukan dengan dua cara yaitu adsorpsi dan sentrifugasi. Adsorpsi dilakukan menggunakan Amberlit IR-120 dengan preparasi melalui pemanasan dan tanpa pemanasan. Hasil yang diperoleh menunjukkan bahwa kalibrasi menggunakan spektrofotmeter cukup akurat dengan koefisien korelasi sebesar 0,997, batas minimum deteksi (limit of detection, LOD) sebesar 0,09 ppm dan batas minimum kuantitasi (limit of quantitation, LOQ) sebesar 0,29 ppm. Perolehan kembali parakuat diklorida secara adsorpsi dengan tanpa pemanasan (66,14-77,54%) lebih tinggi dibandingkan dengan pemanasan (65,21-71,73%) dan sentrifugasi (65,21-67,67%). Hasil analisis beberapa sampel CPO menunjukkan bahwa sampel tidak terdeteksi mengandung residu paraquat diklorida
POTENSI DAN TANTANGAN PENERAPAN PRECISION FARMING DALAM UPAYA MEMBANGUN PERKEBUNAN KELAPA SAWIT YANG BERKELANJUTAN
Authors: Ginting Eko Noviandi , Wiratmoko Dhimas
Published: April 2023

Pertanian presisi atau precision farming (PF) merupakan suatu sistem pengelolaan lahan pertanian yang berbasis informasi keragaman lahan, tanaman, dan iklim untuk menghasilkan suatu keputusan terbaik dengan tujuan untuk memperoleh keuntungan yang optimal, berkelanjutan, dengan tetap menjaga dan melindungi kelestarian lingkungan. Penerapan PF di perkebunan kelapa sawit dimaksudkan untuk mempermudah manajemen kebun dalam mengambil suatu keputusan terhadap berbagai permasalahan yang terjadi. Sistem pengelolaan perkebunan kelapa sawit yang kebanyakan masih dilakukan secara konvensional, baik dalam hal kultur teknis tanaman, pengelolaan tenaga kerja, maupun sistem administrasi, dinilai kurang optimal untuk menjamin keberlanjutan usaha perkebunan kelapa sawit. Oleh karenanya, PF mulai dikembangkan di perkebunan kelapa sawit dalam upaya mengelola seluruh keberagaman permasalahan yang ada secara cepat dan tepat sehingga dapat diambil keputusan yang tepat menyangkut manajemen yang sesuai secara spesifik baik dari segi lokasi, cara, maupun waktu.
REKOMENDASI WAKTU PEMUPUKAN UNTUK 22 ZONA PERKEBUNAN KELAPA SAWIT DI INDONESIA BERDASARKAN POLA CURAH HUJAN

Published: April 2023

Ketidaktepatan waktu pemupukan dapat mengakibatkan peningkatan kehilangan hara sehingga efektivitas dan efisiensi pemupukan menjadi tidak optimal. Penetapan waktu pemupukan umumnya didasarkan pada kondisi curah hujan. Waktu pemupukan yang optimal adalah pada saat curah hujan 100-200 mm/bulan. Pemupukan sebaiknya ditunda jika curah hujan belum mencapai 60 mm/bulan atau melebihi 300 mm/bulan. Namun demikian, tidak semua pekebun kelapa sawit memiliki data curah hujan yang lengkap, sehingga diperlukan informasi mengenai rekomendasi jadwal pemupukan yang umum untuk perkebunan kelapa sawit yang tersebar di berbagai wilayah di Indonesia. Tulisan ini menyajikan rekomendasi jadwal pemupukan di 22 zona yang mewakili sentra-sentra perkebunan kelapa sawit Indonesia. Setiap zona ditentukan jadwal pemupukannya berdasarkan data curah hujan antara 1991-2019 (29 tahun). Informasi jadwal pemupukan tersebut disusun untuk frekuensi pemupukan 2-3 kali per tahun. Selain itu, dicantumkan juga rincian bulan yang sebaiknya dihindari untuk dilakukan pemupukan karena berisiko tinggi meningkatkan kehilangan hara.
PENGARUH CEKAMAN KEKERINGAN TERHADAP FISIOLOGI DAN PRODUKSI KELAPA SAWIT
Authors: Riski Wanriski Fauzi
Published: April 2023

Kelapa sawit  merupakan penghasil terbesar devisa di Indonesia. Dalam perjalanannya sebagai sumber penghasil minyak nabati, kelapa sawit mendapat banyak tantangan, terutama dari perubahan iklim dimana sering terjadi fenomena kekeringan yang berdampak terhadap fisiologi dan produksi kelapa sawit. Cekaman kekeringan terjadi apabila kebutuhan air tanaman tidak dapat tercukupi dengan baik akibat terjadinya defisit air. Defisit air >200 mm menyebabkan fisiologi tanaman terganggu. Cekaman kekeringan menyebabkan perubahan fisiokimia seperti aktivitas Rubisco, mengurangi efisiensi foto, meningkatkan stres metabolit dan enzim antioksidan, ketidakstabilan membran sel, mengurangi kandungan air daun, degradasi pigmen, penurunan bukaan stomata, penurunan kandungan CO2 tanaman, mengurangi laju fotosintesis dan menghambat pertumbuhan tanaman. Cekaman kekeringan dapat menghambat pembukaan pelepah daun muda, merusak hijau daun yang menyebabkan daun tampak menguning dan mengering, pelepah daun terkulai dan pupus patah. Pada fase reproduktif cekaman kekeringan menyebabkan perubahan nisbah kelamin bunga, bunga dan buah muda mengalami keguguran, dan tandan buah gagal menjadi masak, akhirnya mengakibatkan gagal panen dan menurunkan produksi tandan buah segar. Untuk meminimalisir dampak cekaman lingkungan, hal hal yang dapat dilakukan antara lain, melakukan monitoring rutin terhadap kondisi cuaca dan iklim,  menerapkan standar kultur teknis yang baik dan menerapkan teknik konservasi tanah dan air.

Tidak banyak yang tahu bahwa peran perempuan menyumbang kontribusi yang tidak sedikit bagi sektor pertanian dan perkebunan Indonesia. Tidak hanya bertugas menjamin ketahanan pangan keluarga dan aktif di ranah sosial, perempuan juga dapat membantu perekonomian rumah tangga. FAO menyebutkan 60% dari pekerja usaha tani Indonesia adalah sosok perempuan. Cukup banyak literatur yang menjabarkan peran perempuan dalam industri perkebunan kelapa sawit. Namun, tidak banyak kajian peran perempuan yang menitikberatkan di rantai pasok lainnya, seperti sektor hilir dan sisi konsumen. Tulisan ini mengkaji bagaimana peran dan kinerja perempuan dalam perkembangan industri kelapa sawit Indonesia. Studi melalui data sekunder dan analisis non-parametrik Wilcoxon Rank Sum Test menjelaskan secara bernas bahwa kinerja perempuan di beberapa rantai pasok menunjukkan kinerja yang lebih baik dibandingkan gender lainnya. Peran perempuan tidak dapat dinafikan terutama dalam hal penentuan keputusan pembelian suatu barang. Analisis konten menunjukkan bahwa konsumen perempuan lebih elastis terhadap produk kelapa sawit yang bersertifikat keberlanjutan (ISPO/RSPO).
