Published: January 2024

As a transmission medium and heating energy, microwave is widely favored due to its high efficiency, strong selectivity, and easy control. Here, the effects of different heating methods (conventional thermal induction (CI) and microwave induction (MI)) on the polymerization rate of polycarboxylate superplasticizer (PCE) were investigated. Compared with CI, MI significantly boosted the polymerization rate (by approximately 51 times) and markedly decreased the activation energy (Ea), from 46.83 kJ mol−1 to 35.07 kJ mol−1. The polar of the monomers and initiators in the PCE synthesis contributes to varying permittivities and loss factors under the microwave field, which are influenced by their concentration and reaction temperature. The insights gained from the microwave thermal effects and the micro-kinetics of the PCE polymerization system are able to propose theoretical underpinnings for the industrial-scale application of microwave induction polymerization, potentially steering the synthesis of polymer materials towards a more efficient and cleaner process.

Published: January 2024

Specific groups of Catalan citizens, in spite of them being socially and professionally integrated, suffer the risk of exclusion or segregation on grounds of identity, one example being those who identify with Islam. This study arises from a prospective research project centred on a case study with the Catalan Muslim Women’s Association. The main objective was to formulate public policy proposals on education, religion, and gender to be included in the Citizenship and Immigration Plan, through a process based on the women’s participation and testimony. The study was divided into two phases: the participatory research followed by evaluation of the applicability of the resulting proposals. It was conducted through semi-structured interviews (n = 37), a discussion group (n = 21), and a round table (n = 31). Oral and textual qualitative data were gathered and analysed using the Ivàlua logical framework. Results for education policy urge the creation of a new professional specialist mediating between all actors. Those for religion call for public spaces for religious practice. In relation to gender, participants continued to demand policies that do not discriminate against Muslim women. In summary, religion is a resource that supports identities, beliefs, and practices, with both empowering and disempowering effects.
Protestant Medical Missions in Iran: Negotiating Religion and Modernity in Mission Hospitals
Authors: Rzepka Marcin
Published: January 2024

Focusing on the Protestant mission hospitals in Iran during the reign of Reza Pahlavi, this article analyzes the concepts and ideas referred to as medical care in missionary narratives as well as reactions of the Iranians to the missionary medical initiatives. Trying to situate mission hospitals in the context of the rapid social and cultural changes that the Iranians faced because of the implementation of the monarch’s reforms and the policies of centralization, statism, and social uniformity, the article puts emphasis on the fact that mission hospitals introduced a processual and negotiable type of medical modernity different from what was launched by the state at that time. Creating the healthcare networks in Iran, the Protestant hospitals produced the ideal—in the missionaries’ eyes—types of medical modernity that might be presented as the social and cultural roles played by patients, converts, and nurses.
Co-Variability between the Surface Wind Divergence and Vorticity over the Ocean
Authors: Jacobs Robert , O’Neill Larry W.
Published: January 2024

We examine the co-variability between the surface wind divergence and vorticity and how it varies with latitude in the Pacific Ocean using surface vector winds from reanalysis and satellite scatterometer observations. We show a strong correlation between divergence and vorticity throughout the extratropical oceans. From this observation, we develop a dynamical model to explain the first-order dynamics which govern this strong co-variability. Our model exploits the fact that for much of the time, the large-scale surface winds are approximately in a steady-state Ekman balance to first order. An angle α′ is derived from Ekman dynamics by utilizing only the surface divergence and vorticity and is shown to succinctly summarize the co-variability between divergence and vorticity. This approach yields insight into the dynamics that shape the spatial variations in the large-scale surface wind field over the ocean; previous research has focused mainly on explaining variability in the vector winds rather than the derivative wind fields. Our model predicts two steady-state conditions which are easily identifiable as discrete peaks in α′ Probability Distribution Functions (PDFs). In the Northern Hemisphere, steady-state conditions can be either (1) diverging, with negative vorticity, or (2) converging, with positive vorticity. We show that these two states correspond to relative high and low sea-level pressure features, respectively. Southern Hemisphere conditions are similar to those of the Northern Hemisphere, except with the opposite sign of vorticity. This model also predicts the latitudinal variations in the co-variability between divergence and vorticity due to the latitudinal variation in the Coriolis parameter. The main conclusion of this study is that the statistical co-variability between the surface divergence and vorticity over the ocean is consistent with Ekman dynamics and provides perhaps the first dynamical approach for interpreting their statistical distributions. The related α′ PDFs provide a unique method for analyzing air–sea interactions and will likely have applications in evaluating the surface wind fields from scatterometers and weather and reanalysis models.
An Adaptation of the Split-Cylinder Resonator Method for Measuring the Microwave Properties of Thin Ferroelectric Films in a “Thin Film—Substrate” Structure
Authors: Gagarin Alexander , Tsyganova Diana , Altynnikov Andrey , Komlev Andrey , Platonov Roman
Published: January 2024

The split-cylinder resonator method was adapted to measure the microwave properties (dielectric permittivity and loss tangent) of thin ferroelectric films on a dielectric substrate. The mathematical model for calculating the resonance frequency of the split-cylinder resonator was adjusted for the “ferroelectric film—substrate” structure. An approach for correcting the gap effect based on calibrating with a single-layer dielectric was introduced and used to study two-layer dielectrics. The prototype of a split-cylinder resonator designed to measure single-layer dielectric plates at a frequency of 10 GHz was presented. The resonator calibration was performed using dielectric PTFE samples and fused silica, and an example of the correction function was suggested. The measurement error was estimated, and recommendations on the acceptable parameter range for the material under investigation were provided. The method was demonstrated to measure the microwave properties of a ferroelectric film on a fused silica substrate.

Published: January 2024

Despite the large impact chronic obstructive pulmonary disease (COPD) that has on the population, the implementation of new technologies for diagnosis and treatment remains limited. Current practices in ambulatory oxygen therapy used in COPD rely on fixed doses overlooking the diverse activities which patients engage in. To address this challenge, we propose a software architecture aimed at delivering patient-personalized edge-based artificial intelligence (AI)-assisted models that are built upon data collected from patients’ previous experiences along with an evaluation function. The main objectives reside in proactively administering precise oxygen dosages in real time to the patient (the edge), leveraging individual patient data, previous experiences, and actual activity levels, thereby representing a substantial advancement over conventional oxygen dosing. Through a pilot test using vital sign data from a cohort of five patients, the limitations of a one-size-fits-all approach are demonstrated, thus highlighting the need for personalized treatment strategies. This study underscores the importance of adopting advanced technological approaches for ambulatory oxygen therapy.

Published: January 2024

Geoparks, as a modern product of geotourism and territorial management, currently represent a new way of protecting and preserving geoheritage, which is closely related to knowledge and education. They increase general awareness of the value of the Earth and, on the other hand, represent the support and development of the territory. The fulfillment of geopark goals, together with their purpose and activities, emphasizes the need for an effective management structure and function of the whole. This research aimed at clarifying the management issues of geoparks, and defined management areas derived from essential geopark functions. Based on determining management areas and their specifics, the task is to define a suitable management structure applicable in geoparks, representing a supporting link in creating plans and management methods. The task involves a multi-criteria decision-making method to define an appropriate management structure for the geopark. This method helped to define three key areas of management, such as marketing management, cooperation management and, last but not least, destination management. Of course, this does not mean that other areas of management are not important, as they represent an inseparable support structure in management. The usability of the results of this article can serve as support in the creation of management plans, and also indicates priorities in deciding which way to proceed in the management of geoparks as specific entities.

Published: January 2024

The assessment of the health status of healthcare workers (HWs) is related to the growing interest in the sustainability of the medical profession. This study explores for the first time the level of burnout, coping strategies, and pulse wave velocity (PWV), the correlations between them, and possible connections with the workplace. It included 154 HWs, aged 25–64 years, 83.76% women, divided into five groups (oncology, cardiology, intensive care, occupational health, and residents). The Burnout Assessment Tool (BAT-23) questionnaire for the burnout level and the Carver Coping Orientation to Problems Experienced (COPE) questionnaire for the coping strategies were used. PWV was measured with a TensioMed arteriograph. Regarding BAT subscales, all studied groups are at burnout for exhaustion (E), prone to burnout for mental distancing (MD), emotional impairment (EI), and no burnout for cognitive impairment (CI). On the four subscales of the BAT, the MANOVA shows a medium-sized effect of the workplace on MD and on CI. All subjects use positive coping strategies. Problem-solving mechanisms are often used, followed by emotional support-based and social support-based coping. PWV correlates with age and BMI and has a small positive correlation with MD, CI, and EI. High burnout levels are related to the healthcare profession, not to the workplace. Our research shows the practical need to supervise the mental and physical health of HWs in order to preserve their health through medical and organizational methods.
Navigating the Nexus between Rural Revitalization and Sustainable Development: A Bibliometric Analyses of Current Status, Progress, and Prospects
Authors: Cai Mingjun , Ouyang Bin , Quayson Matthew
Published: January 2024

Achieving sustainable rural development is challenging. However, revitalizing the rural economy is one of the most suitable strategies to overcome sustainable development problems. The rural revitalization strategy aims to create an idealized sustainable development model for rural areas which can avoid the current crisis and utilize institutional advantages to overcome the survival challenges of mostly small-scale peasant economies. The logic of the rural revitalization strategy lies in its essential value implication and practical orientation for consolidating the foundation in rural areas, including its characteristics and its ability to realize long-term sustainable development. There is growing interest in research on rural revitalization and sustainable development, but the current status, trends, and progress are unknown. This study examines the most recent advancements in research patterns for rural revitalization and the promotion of sustainable development from 1995 to 2023. It accomplishes this by thoroughly evaluating and analyzing published scholarly material. We performed a bibliometric analysis of the literature obtained from the Scopus database using VOS Viewer software version 1.6.15. We examined a total of 403 articles and evaluated them, focusing on the precise terms “Rural Revitalization” and “Sustainable Development”. We found that post-2018, there has been a notable surge in the popularity and acceptance of research related to these topics. China ranks first in terms of publishing the greatest number of research articles. The journal Sustainability has published the most articles on sustainable development and rural revitalization, followed by Land and the International Journal of Environmental Research and Public Health. The Journal of Rural Studies published the most cited document. Exciting research areas include the conservation of natural resources, ecosystem cities, and rural revitalization strategies. The research findings thoroughly evaluate academic output and propose thematic areas for further investigation.

Published: January 2024

Lumpy skin disease virus (LSDV) has recently undergone rapid spread, now being reported from more than 80 countries, affecting predominantly cattle and to a lesser extent, water buffalo. This poxvirus was previously considered to be highly host-range restricted. However, there is an increasing number of published reports on the detection of the virus from different game animal species. The virus has not only been shown to infect a wide range of game species under experimental conditions, but has also been naturally detected in oryx, giraffe, camels and gazelle. In addition, clinical lumpy skin disease has previously been described in springbok (Antidorcas marsupialis), an African antelope species, in South Africa. This report describes the characterization of lumpy skin disease virus belonging to cluster 1.2, from field samples from springbok, impala (Aepyceros melampus) and a giraffe (Giraffa camelopardalis) in South Africa using PCR, Sanger and whole genome sequencing. Most of these samples were submitted from wild animals in nature reserves or game parks, indicating that the disease is not restricted to captive-bred animals on game farms or zoological gardens. The potential role of wildlife species in the transmission and maintenance of LSDV is further discussed and requires continuing investigation, as the virus and disease may pose a serious threat to endangered species.

Published: January 2024

Histone H1.2 is a member of the linker histone family, which plays extensive and crucial roles not only in the regulation of chromatin dynamics, cell cycle, and cell apoptosis, but also in viral diseases and innate immunity response. Recently, it was discovered that H1.2 regulates interferon-β and inhibits influenza virus replication, whereas its role in other viral infections is poorly reported. Here, we first found the up-regulation of H1.2 during Encephalomyocarditis virus (EMCV) infection, implying that H1.2 was involved in EMCV infection. Overexpression of H1.2 inhibited EMCV proliferation, whereas knockdown of H1.2 showed a significant promotion of virus infection in HEK293T cells. Moreover, we demonstrated that overexpression of H1.2 remarkably enhanced the production of EMCV-induced type I interferon, which may be the crucial factor for H1.2 proliferation–inhibitory effects. We further found that H1.2 up-regulated the expression of the proteins of the MDA5 signaling pathway and interacted with MDA5 and IRF3 in EMCV infection. Further, we demonstrated that H1.2 facilitated EMCV-induced phosphorylation and nuclear translocation of IRF3. Briefly, our research uncovers the mechanism of H1.2 negatively regulating EMCV replication and provides new insight into antiviral targets for EMCV.

Authors: Németová Zuzana , Kohnová Silvia , Sabová Zuzana
Published: January 2024

Among the main elements that contribute to climate change are degradation processes and the ecological level of a landscape. These two topics have been discussed and researched for many years, and many studies have been conducted. The idea behind this article is to determine the correlation between the ecological stability of a territory and the intensity of degradation processes and find out how ecological stability affects the intensity of soil erosion and vice versa. The ecological stability was calculated based on various methods during the years analyzed, i.e., 1990, 2006, 2012, and 2018. The soil water erosion measurements were performed for the same period in order to identify the relationship between ecological stability and the intensity of soil erosion. The investigated area is located in the Slovak Republic, and each year reflects different types of management of the territory, reflecting the current situation in the catchment according to the year evaluated. The intensity of the erosion process was measured using a physically based EROSION-3D model based on the precipitation levels derived using the Community Land Model (the CLM). In addition to identifying the relationship between the level of ecological stability and the intensity of erosion, this study also describes the development of ecological stability during the evaluated period together with changes in soil erosion processes. The results show a dependence between the intensity of ecological stability and soil erosion. First of all, it determines whether such a dependence exists at all and also its extent.
Water Renewal Time in Lakes with Transformed Water Distribution in the Catchment Areas
Authors: Dawidek Jarosław , Ferencz Beata
Published: January 2024

Water exchange in lake basins is a very important process in regulating the health of the aquatic environment, e.g., by shaping algal blooms. Thus, knowledge of the process is also required to develop management strategies. The paper presents a dynamic of water renewal time in the Uściwierz chain of lakes, in which the natural hydrological connectivity of the catchment areas has been altered due to human impact. Calculations of water renewal were limited to the part of the lake basin corresponding to the active (dynamic) retention layer. A comparative analysis of the rate of potential water renewal, based on the structure difference index, was used as an indicator of the degree of anthropogenic transformation of water distribution in the lake catchments. The smallest differences in the structure of the water renewal rate between the neighboring lakes in the chain system were observed in the cold period, and the largest differences were observed in the warm period. The results showed that the shorter the timescale (5-day period), the higher the similarity in the structure of the water renewal rate between the lakes. Very large differences between the structure of the potential water renewal rate in Lakes Uściwierz and Bikcze indicated a significant transformation of the water cycle down the lake chain. The water renewal rate proved to be a good indicator of the degree of anthropogenic transformation in the catchments located in close proximity.
The Water Footprint of Pastoral Dairy Farming: The Effect of Water Footprint Methods, Data Sources and Spatial Scale
Authors: Higham Caleb D. , Singh Ranvir , Horne David J.
Published: January 2024

The water footprint of pastoral dairy milk production was assessed by analysing water use at 28 irrigated and 60 non-irrigated ‘rain-fed’ pastoral dairy farms in three regions of New Zealand. Two water footprint methods, the WFN-based blue water footprint impact index (WFIIblue) and the Available WAter REmaining (AWARE) water scarcity footprint (WFAWARE), were evaluated using different sets of global or local data sources, different rates of environmental flow requirements, and the regional or catchment scale of the analysis. A majority (~99%) of the consumptive water footprint of a unit of pastoral dairy milk production (L/kg of fat- and protein-corrected milk) was quantified as being associated with green and blue water consumption via evapotranspiration for pasture and feed used at the studied dairy farms. The quantified WFIIblue (-) and WFAWARE (m3 world eq./kg of FPCM) indices ranked in a similar order (from lowest to highest) regarding the water scarcity footprint impact associated with pastoral dairy milk production across the study regions and catchments. However, use of the global or local data sets significantly affected the quantification and comparative rankings of the WFIIblue and WFAWARE values. Compared to the local data sets, using the global data sets resulted in significant under- or overestimation of the WFIIblue and WFAWARE values across the study regions and catchments. A catchment-scale analysis using locally available data sets and calibrated models is recommended to robustly assess water consumption and its associated water scarcity impact due to pastoral dairy milk production in local catchments.

Published: January 2024

The permeability of sand is an important factor in determining the movement and occurrence of liquids and gases in sand. The current work studied the influence of soil particle size and gradation on permeability by testing the permeability of different sand samples that consist of defined sand particles in certain ratios. The results of a total of 640 sets of experiments were analyzed and compared with the corresponding theoretical calculations. We found that the sand can be divided into four groups based on particle size: high-permeability particles, medium-permeability particles, low-permeability particles and non-permeable particles; and the critical particle size of sand for permeability is 0.050 mm. Permeation will be lost when non-permeable particles account for >75% of the total in the mixture of high-permeability particles and non-permeable particles. Permeation will be very easily lost when medium- or low-permeability particles are mixed with non-permeable particles. The current findings are of importance for assessing the permeability of sand based on particle size.

AbstrakPenulisan artikel ini berfokus pada Yesus Sebagai Teladan Untuk Menjadi Gembala Yang Baik Berdasarkan Perspektif Injil Yohanes 10:11-16. Petrus berkata “gembalakanlah kawanan domba Allah jangan dengan paksa dan mencari keuntungan melainkan dengan kehendak Allah, kerelaan dan pengabdian diri”. (1 Petrus 5:2). Hal ini menjelaskan bahwa ada gaya kepemimpinan penggembalaan yang belum memahami kebutuhan umatnya. Umat seringkali mengalami krisis iman karena gembalanya memerintah dengan keangkuhan dan egoisme. Tujuan dari penulisan artikel ini adalah membahas dan menggali makna menjadi gembala yang baik seperti teladan Yesus, berdasarkan perspektif injil Yohanes 10:11-16. Metode yang digunakan adalah kualitatif deskriptif dengan metode studi literatur dan tafsiran-eksegese. Hasil temuannya, gembala yang baik adalah gembala yang menjalankan tugas dengan menghayati dan meniru teladan Yesus selama karya-Nya di dunia, yakni mulai dari hidup, sengsara, wafat dan kebangkitan. Kesimpulannya gembala yang baik harus menunjukan teladan moral yang baik, mewartakan keselamatan, gembala yang berbau domba dan berani mengorbankan diri. Ini mau menggambarkan karya, sengsara, wafat dan kebangkitan Yesus.

Published: January 2024

Ensuring water resource security and enhancing resilience to extreme hydrological events demand a comprehensive understanding of water dynamics across various scales. However, monitoring water bodies with highly seasonal hydrological variability, particularly using medium-resolution satellite imagery such as Landsat 4-9, presents substantial challenges. This study introduces the Normalized Difference Water Fraction Index (NDWFI) based on spectral mixture analysis (SMA) to improve the detection of subtle and dynamically changing water bodies. First, the effectiveness of NDWFI is rigorously assessed across four challenging sites. The findings reveal that NDWFI achieves an average overall accuracy (OA) of 98.2% in water extraction across a range of water-covered scenarios, surpassing conventional water indices. Subsequently, using approximately 11,000 Landsat satellite images and NDWFI within the Google Earth Engine (GEE) platform, this study generates a high-resolution surface water (SW) map for Jiangsu Province, China, exhibiting an impressive OA of 95.91% ± 0.23%. We also investigate the stability of the NDWFI threshold for water extraction and its superior performance in comparison to existing thematic water maps. This research offers a promising avenue to address crucial challenges in remote sensing hydrology monitoring, contributing to the enhancement of water security and the strengthening of resilience against hydrological extremes.

Prevelensi anemia meningkat dua tahun terakhir. Tujuan Penelitian ini mengetahui hubungan limgkar lengan atas (LILA) dengan kadar hemoglobin (Hb) pada ibu bersalin. Desain penelitian ini Cross Sectional. Sampel penelitian ini ibu bersalin berjumlah 43 responden, teknik pengambilan sampelnya menggunakan total sampling. Penelitian ini dilaksanakan di Praktek Mandiri Bidan Rosita Pekanbaru, instrumen penelitian adalah pita ukur LILA dan easy touch untuk mengukur kadar Hb . Data dianalisis dengan uji Chi Square dengan signifikan p<0,5. Hasil penelitian menunjukkan ibu bersalin dengan LILA kurang (< 23,5 cm) memiliki 5 kali (OR=5,11, 95% CI : 1,28-20,49) lebih besar kemungkinan mengalami anemia dari pada ibu bersalin yang LILA normal, ada hubungan lingkar lengan atas dengan kadar hemoglobin ibu bersalin dengan (p < 0,05). Lingkar lengan atas yang merupakan indikator status gizi ibu bersalin, jika dibawah standar (< 23,5)  beresiko untuk anemia.
FINITE ELEMENT ANALYSIS OF REINFORCED AND UNREINFORCED DEEP SOIL MIXING COLUMNS INSTALLED IN COHESIVE AND NON-COHESIVE SOILS

A parametric study employing three-dimensional finite element analysis is used in this paper to examine the improvement of soft clay and silty loose sand under a road embankment using deep soil mixing (DSM) columns. Both soils are designed with three variables namely DSM column diameter (D), DSM column length (L) and centre-to-centre distance of the DSM columns (s). The settlement values under the road embankment constructed with and without DSM columns were obtained by numerical analysis. The analyses were also repeated for the DSM columns which were stiffened by adding I-profiles. The results showed that the improvement effect of the DSM columns on settlement is higher in soft clay. For constant improvement area ratio (ar), the maximum improvement is achieved for D = 80 cm (2.62 ft.) and increasing D did not affect the degree of improvement. In both soil types, settlement decreased with increasing L within the weak soil zone. Increasing L into the comparatively stronger soil did not significantly affect the settlement value. Although the settlement decreased with increasing ar in silty loose sand, it reached at maximum in soft clay at ar of thirty-five percent and was not affected thereafter with increasing ar values.

Buah naga, juga dikenal sebagai dragon fruit, adalah buah yang berasal dari tanaman kaktus yang termasuk dalam genus Hylocereus dan Selenicereus, family Cactaceae, ordo Cactaes, dan kelas Dicotyledonae. Buah naga sangat populer di kalangan masyarakat karena memiliki berbagai manfaat kesehatan. Pematangan buah naga dimulai sekitar 11 bulan setelah tanam, dan membutuhkan waktu sekitar 50 sampai 55 hari dari saat kuncup bunga hingga buah siap panen. Proses pematangan buah naga dimulai sekitar 11 bulan setelah penanaman. Dari saat kuncup bunga terbentuk hingga buah siap untuk dipanen, dibutuhkan waktu sekitar 50 sampai 55 hari. Buah naga memiliki tingkat kematangan yang berbeda, yaitu mentah, setengah matang, matang, dan terlalu matang. Tingkat kematangan ini dapat dikenali melalui perubahan warna kulit buah. Saat ini, petani masih melakukan penyortiran buah naga secara manual dengan mengamati secara langsung permukaan buah, namun metode ini sering menghasilkan klasifikasi yang tidak akurat dan tidak konsisten karena adanya keteledoran pada manusia. Oleh karena itu, peneliti berupaya untuk mengembangkan sebuah sistem yang dapat mengklasifikasikan tingkat kematangan buah naga dengan memanfaatkan karakteristik warna Hue Saturation Value (HSV) dan menerapkan metode Gray Level Co-Occurrence Matrix (GLCM). Dalam sistem klasifikasi yang dikembangkan menggunakan perangkat lunak Matlab, terdapat empat kategori kematangan buah naga yang termasuk yaitu, mentah, setengah matang, matang, dan terlalu matang. Terdapat 100 dataset yang digunakan dalam penelitian ini dan melalui pengujian dengan menggunakan 5-fold-cross validation. Penelitian ini mencapai akurasi terbaik sebesar 90%. Analisis data dilakukan menggunakan metode GLCM dengan menghitung jarak terdekat antara setiap data latihan dan data pengujian yang sama menggunakan rumus jarak Euclidean.

Salah satu aset terpenting perusahaan adalah pelanggannya. Berbagai cara dilakukan oleh perusahaan untuk mempertahankan pelanggan dengan menerapkan berbagai startegi seperti pada PT Bintang Multi Sarana yang melakukan berbagai macam cara untuk menjalin hubungan baik dengan pelanggan seperti mengadakan promo dan diskon. Perusahaan menawarkan barang promo atau diskon dengan cara menghubungi pelanggan melalui telepon satu per satu atau menawarkan secara langsung ketika pelanggan selesai membeli barang sebelumnya. Penawaran diskon dan promo keseluruh pelanggan ini kurang efisien karena memakan banyak biaya untuk operasioanl dan menyita banyak waktu. Oleh sebab itu, pelanggan yang ada di PT Bintang Multi Sarana perlu dikelompokan terlebih dahulu agar dapat mempermudah perusahaan dalam menentukan layanan yang sesuai. Selain itu data transaksi penjualan pada PT Bintang Multi Sarana hanya diolah menjadi laporan bulanan saja.  Padahal jika diolah dengan tepat, data transaksi penjualan dapat digunakan untuk membantu menentukan strategi dalam mempertahankan pelanggan. Tujuan penelitian ini yaitu melakukan segmentasi pelanggan untuk mengetahui karakteristik pelanggan. Salah satu solusi untuk permasalahan tersebut yaitu dengan mengolah data transaksi penjualan dengan memanfaatkan peran dari data mining dengan teknik clustering menggunakan algoritma k-means. Algoritma k-means merupakan algoritma berbasis jarak yang membagi data kedalam cluster terpisah. Berdasarkan perhitungan menggunakan k-means, pelanggan tercluster kedalam 3 kelompok yaitu cluster 1 sebanyak 742 pelanggan, cluster 2 sebanyak 795 pelanggan dan cluster 3 sebanyak 223 pelanggan. Dari hasil analisis segmentasi pelanggan diperoleh hasil bahwa cluster 1 merupakan pelanggan segmen silver, cluster 2 pelanggan segmen gold, dan cluster 3 pelanggan segmen platinum. Adapun strategi pemasaran untuk segmen silver dengan pemberian diskon harga, promosi dan iklan di media sosial, untuk segmen gold diberikan layanan berupa point reward atau diskon khusus, sedangkan untuk segmen platinum yaitu pemberian hadiah menarik, atau akses eksklusif terhadap produk tertentu.
