Contested discourses in social tourism: a relational political economy perspective.
Authors: Bianchi Raoul , McCabe Scott , Martínez José David Cisneros , Domínguez-Gómez J. Andrés
Published: August 2023

Social tourism initiatives often have economic as well as objectives, particularly national schemes such as the Spanish IMSERSO programme, designed to stimulate off-season tourism in mass coastal tourism destinations. Yet, there is little evidence of how such schemes responded to crises or that explores the effects on the tourism industry actors responsible for programme delivery. This article applies a relational political economy approach to assess the contested discourses surrounding the governance of the scheme. We examine the evolution of the IMSERSO programme longitudinally following the global financial crisis and up until the COVID-19 pandemic to assess the relational dynamics at play social tourism governance on destination stakeholders, outlining implications for social tourism policies internationally.

AbstractThis paper aims to analyze the birth of new civilizations as a result of global political conflicts with Samuel Huntington's explanation and compare them with the current state of Indonesia. The research method used is critical discourse analysis. Conclusion The review of the book Clash of Civilizations and the Future of World Politics will be explained using critical discourse analysis where in fact some of the predictions written tend to touch several countries in the world, but some don't. For example, Indonesia is able to place itself in global politics dynamically, such as being in a non-aligned and G20 country, and is not touched by friction, clashes or conflicts of shifting civilizations because it has two strong things, namely the nation's motto Bhineka Tunggal Ika and the Pancasila state foundation and many are asked to participate. involved as a peacemaker in horizontal conflicts and humanitarian conflicts in several countries.Keywords: Samuel P.

Authors: Wusqo Urwatul
Published: August 2023

Along with the development of the times, da'wah activities have experienced significant developments, especially in the media sector, namely that they are no longer only carried out on the pulpit but can be through music. The existence of music that is close to the community makes music an effective alternative medium of propaganda. Based on this, this study wants to see the da'wah messages contained in Ebiet G. Ade's song entitled For Us to Reflect. The type of research used is qualitative by using the literature review method. Van Dijk's critical discourse analysis as an approach in this study is to examine the meaning of a language with the process of meaning production and reproduction. The da'wah message contained in Ebiet G. Ade's song entitled "For Us to Think About" is a message about morals, namely remembering and inviting people to improve themselves and repent because all the bad things caused by human behavior will have a bad impact on both the man himself and himself. environment. Apart from containing messages of preaching in the form of morals, it is also in the form of the belief that humans live on earth because of Allah and how humans believe and accept the destiny that Allah wants and humans as servants of Allah so that they always return to Him.Keywords: Da'wah, Music, Van Dijk's critical discourse

Authors: Alifuddin Muhammad , Rosmini Rosmini
Published: August 2023

Research on: Muhammadiyah Social Da'wah for Earthquake Survivors in Ahu Hamlet, besides aiming to find out the patterns and approaches of Muhammadiyah social da'wah to related communities, also critically analyzes the orientation and goals of the da'wah movement in question. The research data were obtained through participatory observation, in-depth interviews and document review. The data obtained were analyzed using the Miles and Huberman paradigm combined with the Von Eckarberg hermeneutic phenomenological analysis model. Referring to the description and analysis of the research data, it is concluded that MDMC's active mitigation efforts for earthquake survivors in Ahu were not only full of social activities, but also filled with preaching. The transmission of values and morals as one of the goals of da'wah, is implemented with an integral comprehensive pattern and approach. That is a pattern that combines verbal appeals (dakwah bi al-lisan) with real action on the ground (dakwah bi al-hal/amal). It is in this context that Muhammadiyah preaching for the survivors of Dusun Ahu is not just an appeal but at the same time running an institutional capacity strengthening program, with the aim that the survivors are able to face the reality of natural disasters that befall them with a positive attitude. MDMC's social da'wah movements and activities are oriented towards strengthening and dynamic social change, taking sides with weak and marginal groups and strengthening civil society for universal human progress and welfare, regardless of ethnic background, religion and organizational affiliation. Thus MDMC's active social preaching in the mitigation space is inclusive.Keywords: Da'wah, Muhammadiyah, Earthquake Survivors.
72 Jam Pertama Pendekatan Komunikasi Risiko Untuk Kesiapsiagaan Bencana
Authors: Putra Fajar Dwi
Published: August 2023

Disasters are caused by the interaction of biophysical systems, human systems, and the built environment. Disaster management with a lack of understanding and context of risk communication. When a major disaster occurs, recovery requires a massive infusion of external public and private resources, but what happens is that conditions are highly unequal, and likely to produce many of the pre-existing inequities in exposure and vulnerability. This research focuses on the first 72 hours of disaster relief through effective communication in the case of the 13 June 2022 tornado in Yogyakarta. The purpose of this study is to provide education about the first 72 hours that must be carried out in handling disaster cases through an effective and central communication channel. The research method used is qualitative, existential phenomenology and the paradigm built is constructivism. The findings in the field show that the people of Yogyakarta still lack knowledge about how to communicate effectively in dealing with disasters such as a lack of evacuation training, minimal communication tools, minimal evacuation route maps, even in the context of a tornado disaster, no residents know what to do. to do and to whom they should communicate first. The potential impact of ineffective communication; more and more victims, disaster losses increased partly because the way to design and build communication is wrong and not on target. Many people speculate about the causes of disasters, the minimal contribution of society to increased exposure to hazards often results in damage to environmental resources such as the collapse of people's houses and damage to public facilities. Initial disaster failure; identifying communication lines to ensure evacuation of highly vulnerable environments should be known before disaster. Improvement of long-term communication lines needs to be improved by mapping community communication patterns, communication tools and who is the first person to contact.Keywords: Risk Communication, Disaster Communication, Disaster Evacuation, Communication Lines

Published: August 2023

In 2020-2021 there has been much discussion of the pros and cons of the Draft Law on the Rancangan Undang-Undang Penghapusan Kekerasan Seksual (RUU-PKS) in online media. Each media has its own ideology, therefore this study aims to look at the framing of two media with different ideologies in reporting the RUU-PKS. The media are Suara.com and Hidayatullah.com where it can be seen that the media's attitude is in the form of pros or cons towards the RUU-PKS. This study uses a qualitative methodology of collecting news documents which are then taken as samples through a purposive sampling technique. Researchers used Zhondang Pan and Gerald M. Kosicki's framing analysis model to analyze the samples. Researchers found that Suara.com and Hidayatullah.com prioritize speed in providing information and prioritize media ideology so that it is very clear in giving partiality to the pros and cons. The findings are in the form of a comparative thing between the online media Suara.com and Hidayatullah.com. It was found that Suara.com sided with the ratification of the RUU-PKS. While Hidayatullah.com is on the opposite side of the ratification of the bill. This is shown by the way the two media forms framing, starting from giving titles, emphasizing facts, and so on. As online media whose content spreads quickly, Suara.com and Hidayatullah.com should consider whether their publications can make conditions worse or calm conditions.Keywords: Framing, Issues of RUU-PKS, Media Differences, Media Ideology

Authors: Shofiyah St. , Cangara Hafied
Published: August 2023

Abstract The concept of conflict management often focuses only on how to stop the conflict. However, how to prevent these conflicts from happening again, and how to maintain permanent peace, often escapes scientific studies and the attention of conflict theorists and parties concerned with world peace. Based on this phenomenon, Bar-Siman-Tov developed a theory regarding the creation of lasting peace (stable peace) through a dialectic between the "peace approach" (top down structural) and the "reconciliation approach" (bottom up social psychological). The research is aimed at analyzing the Ambon conflict using the Bar-Siman-Tov theory. The Ambon conflict is a big story in the history of the Indonesian nation. Maluku,  known as a peaceful region with all its plurality, was tested in 1999-2002 by a major conflict. The method used is the library method by collecting data through various written sources. The results of the study show that the dialectic of a structural "peace approach" with a grassroots "reconciliation approach" is capable of creating stable peace. Keywords: stable peace; peace; reconciliation; dialectics

Penelitian ini berangkat dari permasalahan yang terdapat pada Q.S. Al-‘Ankabu>t/29:45 dalam memahami maksud shalat yang dapat mencegah perbuatan fah{sya>’ dan munkar. Penelitian ini bertujuan untuk membandingkan antara penafsiran Al-Qurt}ubi> dalam Tafsi>r al-Jami’ Li Ah}kam al-Qur’an dan penafsiran Hamka dalam Tafsir al-Azhar yang merupakan dua ulama dari bidang keilmuan tafsir yang berbeda. Penelitian ini menggunakan jenis penelitian kualitatif yang menghasilkan data deskriptif melalui riset kepustakaan (library research). Dan menggunakan metode muqa>ran untuk membandingkan kedua kitab tafsir tersebut. Hasil yang ditemukan mengungkapkan bahwa Al-Qurt}ubi> memahami shalat yang dapat mencegah perbuatan fah}sya> dan munkar adalah yang di dalam setiap gerakan pergerakan atau setiap amalan yang dikerjakan baik dari niat untuk wudhu, niat melaksanakan shalat, masuk ke mihrab, takbiratul ihram, sampai salam, masing-masing terdapat zikir di dalamnya. Sehingga zikir yang diulang-ulangi tersebut menjadi kekuatan yang memberikan efek hingga di luar shalat dan menjadikan pelaku yang mengerjakan shalat tersebut terhindar dari perbuatan fah}sya> dan munkar. Sedangkan Hamka tidak memahami ayat ini dari hal tersebut, beliau memaknai shalat yang mencegah perbuatan fah}sya> dan munkar yang dimaksud adalah shalat secara keseluruhan, yakni gerakan dan zikir mencakup suatu kesatuan yang utuh. Kemudian hal itulah yang memberikan dampak pada aktifitas diluar shalat dalam kehidupan sehari-hari dan menjadikan pelaku shalat tersebut terhindar dari perbuatan-perbuatan fah}sya> dan munkar. Perbedaan penafsiran keduanya dipengaruhi oleh latar belakang kehidupan dan bidang keilmuan kedua mufassir. Sehingga mempengaruhi cara penafsiran mereka dalam memaknai Q.S. al-‘Ankabu>t/29:45, yang mana Al-Qurt}ubi> merupakan ulama pada Era klasik yang terkenal dengan keilmuan fiqihnya dan kitabnya yang bercorak Fiqih, sedangkan Hamka merupakan ulama pada Era kontemporer yang terkenal dengan tasawuf modernnya dan kitabnya yang bercorak al-Adab al-Ijtima’i.

Published: August 2023

Research on perovskite solar cells employing tin to replace or partially replace lead is becoming morepopular because ofthe recent achievement of about 24.2% conversion efficiency for ecologically benign mixed Pb-Sn perovskite solar cells. However,a smaller effect on cohesive energies caused by the addition of a Sn metal has a considerable effect on thermodynamic properties of Pb-Sn perovskitesunder high-temperature effects. Thispaper investigates the roleof formamidiniumin the electronic and thermodynamic propertiesofMA(Pb: Sn)I3perovskite alloy using density functional theoryand CASTEP analysis through the Materials Studio. The intended A-cation perovskites have typical compounds FAxMA1-xSn0.5Pb0.5I3, where x=0, 0.2, 0.4 and 0.6.The control and FA-based perovskites were computed through CASTEP analysis from Material studio todetermine the electronic and thermodynamic properties. The findings revealed an improved thermodynamic properties of FA added perovskitescompared to control oneswhereby no significant effect was found in band gap of MAPb0.5Sn0.5I3 perovskite due to addition of formamidinium.However, when x is above 0.5, the quality of the perovskite filmsdeclined, with a wide grain size dispersion and little crystallization as well asthe phase impuritieswere detected. This necessitated a theoretical approach to achieve an optimum amount of FA additive required to improve the properties as well as providing a theoretical guidance for improving the properties of perovskite materials before carrying out experiments. Furthermore, the study predictsthat itispossible to create a stablethermalMA(Pb:Sn)I3alloy, ifthere isa well-thought-out design, which lays a foundation for the development and application of tin-lead mixed perovskite devices

Due to the ever-growing threat of malware application, diverse malware detection mechanism has been developed byresearchers. Malware detection relates to the procedure of finding malware on a host device or determining whether a particular program ismalicious or benign. An instance of a malware detection mechanism is an anti-malware program designed to automatically identify malicious programs from the benign program to prevent damage to the host system.The methodologyusedincorporatedcutting-edge detection techniques to providean effective solution to the problem of malicious programs. This study applied a support vector machine and random forest algorithm on malware detection using a dataset obtained from the Kaggle machine learning repository webpage.In an approach to provide a feasible solution, this study structured three methodical approaches that encompass data filtering techniques referred to as preprocessing and the utilization of the correlation metric to select the most relevant features in the first phase. The second approach involves the application of the filtered and selected dataset attributes and tuples to the adapted machine learning models in particular the random forest algorithm and the support vector machine. The final phase as an approach covers the evaluation of the derived model performance using metrics such as precision, accuracy score,and, f1_score. From the statistical result from the two models concerningthe evaluation metrics also, it can be deduced that the random forest classifier performs more effectively in the detection of malicious malware from the dataset sourced from the Kaggle machine learning repository.
Effect of Zero-Sap Antiwear/Ep Lubricant Additives on Nano-Mechanical Properties of Tribofilms Formed on AISI 52100 Steel Grade
Authors: L.A Animashaun  , Yekinni A.A , Adesina A.O
Published: August 2023

Numerous nations have recently passed stricter environmental legislation due to excessive release of harmful emissions like sulfur (S), phosphorus (P), and zinc (Zn) in conventional lubricating oil additives used in contemporary internal combustion engines. Use of borate ester lubricant additives with no sulfated ash, phosphorus, or sulfur effect (zero-SAPS) is one way to reduce this effect. The resistance of tribofilms from oils containing borate esters on AISI 52100 steel grade to plastic deformation is not entirely understood, yet. This study compares Zinc Dialkyl Dithiophosphate (ZDDP) to the tribological performance and Nano-mechanical behavior of tribofilms made from each of the antiwear/extreme pressure borate esters in Polyalphaolefin (PAO6) base oil. According to tribological test findings on a reciprocating steel pin-on-steel plate sliding rig, the boundary films formed by the borate esters reduced friction and wear in a manner similar to that of ZDDP. On the wear scar, the Nano-indentation technique was used to characterize the Nano-mechanical properties of the tribofilms. The ratios of reduced elastic modulus to hardness (E’/H) for the tribofilms of both borate esters are not only higher than the steel substrate but also comparable to ZDDP. This shows that boron-containing tribofilms offered ZDDP-like tribological performance and also have the ability to release absorbed frictional energy when moving across elastic asperity contacts. Consequently, using borate additives in lubricating oils in IC engines is a method of reducing exhaust emission modern vehicles without adversely affecting tribological performance.Key Words:Anti-wear Additives, Borate Esters, Plasticity Index.

Published: August 2023

The company focuses on producing quality products by implementing the Toyota Production System, known as TPS. The current constraint is the absence of maintenance on the Leak Test, thereby reducing production profits caused by high engine damage. This also causes the average repair time for the Leak Test Model 4L45W engine to be above the repair target set by the company, where the company targets an average repair time per month of 12 minutes. For this reason, corrective steps are needed so that the production process runs smoothly according to operational standards. This step involves proposing the implementation of Total Productive Maintenance (TPM). It is known that the average Overall Equipment Effectiveness (OEE) Leak Test machine in June–August was 60.09%. The Japan Institute of Plant Maintenance (JIPM) stipulates that if the OEE value is equal to 60%, it indicates that there is a lot of room for improvement. After implementing Total Productive Maintenance (TPM) on the Leak Testin September, the OEE value rose to 94.33%, and the average monthly repair timemet the company's target of 9.2 minutes. This greatly affects the cost of production due to lower production costs due to overtime. This indicates improvement, and the first step in the proposed implementation of the Total Productive Maintenance Machine Leak Test model 4L45W is said to be successful

PT. XYZ is a company engaged in the field of Automotive Parts Manufacturer. In carrying out its production this company uses make to order. The company carries out simple planning and scheduling, namely FCFS (First Come First Serve). The company has a problem, namely there is no production scheduling with the appropriate machine assignment. This causes the company to sometimes experience delays in completing the product. The purpose of this study is to overcome scheduling problems in companies to minimize order completion time (makespan). The method used in this study is the Heuristic Pour method, namely the development of a new heuristic algorithm in completing flowshop scheduling with the aim of minimizing makespan based on a combination approach and Genetic Algorithm which will be assisted with the help of MATLAB R2016a software which is a computational algorithm commonly used to solve a search for values in an optimization problem. Based on the data processing that has been done, the results of production scheduling are obtained using the Heuristic Pour method in the order Job 4 (J4)-Job 2 (J2) -Job 7 (J7) -Job 6 (J6) -Job 5 (J5) -Job 3 (J3) ) -Job 1 (J1) gets a makespan of 19440 minutes or equal to 16 working days with a total delay of 1 working day. While production scheduling with the selected Genetic Algorithm method getsthe order Job 4 (J4) -Job 2 (J2) -Job 7 (J7) -Job 6 (J6) -Job 3 (J3) -Job 1 (J1) -Job 5 ( J5) with the best makespan of 18660 minutes or 15 days, and there was no delay in completing requests. The company is expected to consider or review the use of the appropriate production scheduling method because it can provide a more optimum demand completion time (makespan), so the company can reduce delays in fulfilling customer requests.

Published: August 2023

OBJECTIVE

Confocal laser endomicroscopy (CLE) is a US Food and Drug Administration–cleared intraoperative real-time fluorescence-based cellular resolution imaging technology that has been shown to image brain tumor histoarchitecture rapidly in vivo during neuro-oncological surgical procedures. An important goal for successful intraoperative implementation is in vivo use at the margins of infiltrating gliomas. However, CLE use at glioma margins has not been well studied.

METHODS

Matching in vivo CLE images and tissue biopsies acquired at glioma margin regions of interest (ROIs) were collected from 2 institutions. All images were reviewed by 4 neuropathologists experienced in CLE. A scoring system based on the pathological features was implemented to score CLE and H&E images from each ROI on a scale from 0 to 5. Based on the H&E scores, all ROIs were divided into a low tumor probability (LTP) group (scores 0–2) and a high tumor probability (HTP) group (scores 3–5). The concordance between CLE and H&E scores regarding tumor probability was determined. The intraclass correlation coefficient (ICC) and diagnostic performance were calculated.

RESULTS

Fifty-six glioma margin ROIs were included for analysis. Interrater reliability of the scoring system was excellent when used for H&E images (ICC [95% CI] 0.91 [0.86–0.94]) and moderate when used for CLE images (ICC [95% CI] 0.69 [0.40–0.83]). The ICCs (95% CIs) of the LTP group (0.68 [0.40–0.83]) and HTP group (0.68 [0.39–0.83]) did not differ significantly. The concordance between CLE and H&E scores was 61.6%. The sensitivity and specificity values of the scoring system were 79% and 37%. The positive predictive value (PPV) and negative predictive value were 65% and 53%, respectively. Concordance, sensitivity, and PPV were greater in the HTP group than in the LTP group. Specificity was higher in the newly diagnosed group than in the recurrent group.

CONCLUSIONS

CLE may detect tumor infiltration at glioma margins. However, it is not currently dependable, especially in scenarios where low probability of tumor infiltration is expected. The proposed scoring system has excellent intrinsic interrater reliability, but its interrater reliability is only moderate when used with CLE images. These results suggest that this technology requires further exploration as a method for consistent actionable intraoperative guidance with high dependability across the range of tumor margin scenarios.

OBJECTIVE

Ventriculoperitoneal shunting, the most common treatment for the neurological disorder hydrocephalus, has a failure rate of up to 98% within 10 years of placement, mainly because of proximal obstruction of the ventricular catheter (VC). The authors developed a new VC design modified with tethered liquid perfluorocarbon (TLP) and tested it in a porcine model of hydrocephalus. In this study, they aimed to determine if their TLP VC design reduced cell surface attachment and consequent shunt obstruction in the pig model.

METHODS

TLP VCs were designed to reduce drainage hole obstruction using modified TLP and slightly enlarged draining holes, but their number and placement remained very similar to standard VCs. First, the authors tested the device in nonhydrocephalic rats to assess biocompatibility. After confirming safety, they implanted the VCs in hydrocephalic pigs. Hydrocephalus was induced by intracisternal kaolin injections in 30-day-old domestic juvenile pigs. Surgical implantation of the ventriculoperitoneal shunt (clinical control or TLP) was performed 10–14 days postinduction and maintained up to 30 days posttreatment. MRI was performed to measure ventricular volume before treatment and 10 and 30 days after treatment. Histological and immunohistochemical analyses of brain tissue and explanted VCs, intracranial pressure measurement, and clinical scoring were performed when the animals were euthanized.

RESULTS

TLP VCs showed a similar surgical feel, kink resistance, and stiffness to control VCs. In rats (biocompatibility assessment), TLP VCs did not show brain inflammatory reactions after 30 or 60 days of implantation. In pigs, TLP VCs demonstrated increased survival time, improved clinical outcome scores, and significantly reduced total attached cells on the VCs compared with standard clinical control VCs. TLP VCs exhibited similar, but not worse, results related to ventriculomegaly, intracranial pressure, and the local tissue response around the cortical shunt track in pigs.

CONCLUSIONS

TLP VCs may be a strong candidate to reduce proximal VC obstruction and improve hydrocephalus treatment.

OBJECTIVE

Necrotizing enterocolitis (NEC) and posthemorrhagic hydrocephalus are both conditions that can affect preterm infants. The peritoneum is the preferred terminus for shunt placement, but another terminus is sometimes used due to subjective concerns about infection and complications related to NEC. The aim of this study was to examine the rates of ventriculoatrial (VA) and ventriculoperitoneal (VP) shunt infection and failure in pediatric patients with a history of NEC.

METHODS

A single-center retrospective review of medical records from 2009 to 2021 was performed to identify pediatric patients with NEC who underwent shunt placement before 2 years of age. Patients were excluded if shunt placement preceded NEC diagnosis. Patient demographic characteristics, timing of shunt placement, type of shunt, shunt infections or revisions, and timing and management of NEC were extracted. The Student t-test and Fisher exact test were used to calculate significance. Kaplan-Meier curves were calculated.

RESULTS

Twenty-two patients met the inclusion criteria. Most patients underwent VP shunt placement (16 [71.4%]). Patients who underwent surgical management of NEC compared with those who underwent medical management were more likely to have a VA shunt placed (p = 0.02). One VA shunt and 3 VP shunts became infected during follow-up (p = 0.7). The mean time until infection was not significantly different between VA and VP shunts (p = 0.73). Significantly more VA shunts required revision (83% vs 31%, p = 0.04), and VA shunts had a significantly shorter time until failure (3.0 ± 0.8 vs 46.3 ± 7.55 months, p = 0.03).

CONCLUSIONS

VP shunts had a significantly longer time until failure than VA shunts; these shunts had similar infection rates in infants with prior NEC. When feasible, neurosurgeons and pediatric general surgeons can consider placing a VP shunt even if the patient has a history of NEC.

OBJECTIVE

There is ongoing debate on the relative benefits and drawbacks of polyetheretherketone (PEEK) versus titanium (Ti) in generating a bone-to-implant surface microenvironment conducive to osseointegration. Micro- and nanoscale internal and topographic cage modifications have recently been posited to facilitate osseointegration and fusion, but human in vivo confirmation remains lacking. The authors of this study sought to directly compare early radiological outcomes in adults undergoing 1- and 2-level transforaminal lumbar interbody fusion (TLIF) procedures using either PEEK or nano-etched Ti interbody cages with an incorporated microlattice structure.

METHODS

Patients were enrolled in a single academic center using a single-blind randomized controlled superiority design. Screening was undertaken from a pool of consecutive patients eligible for TLIF to undergo placement in a 1:1 ratio of either lordotic PEEK or activated Ti cages at each level of 1- or 2-level procedures. An a priori power analysis was performed and a preplanned interim analysis was undertaken once 50 of 70 patients were enrolled. Patient study data were collected perioperatively and uploaded to a Research Electronic Data Capture (REDCap) registry. Interbody fusion was assessed based on 6-month postoperative lumbar dual-energy CT (DECT) studies using the method of Brantigan and Steffee, as modified to describe the Fraser definition of locked pseudarthrosis (Brantigan-Steffee-Fraser [BSF] scale).

RESULTS

In the final cohort of 50 patients, 40 interbody levels implanted with PEEK cages were compared with 34 interbody levels with activated Ti cages. The trial was stopped early given the results of an interim analysis with respect to the primary outcome. Surgical parameters including number of levels treated, average cage height, and position were not different between groups. For the PEEK and activated Ti groups, 20.6% versus 84.0% demonstrated BSF grade 3 fusion on 6-month postoperative DECT imaging (p < 0.001). Subsidence at 6 months on DECT was identified in 12 (41.4%) of PEEK levels versus 5 (20.8%) of activated Ti levels (p < 0.001). BSF-3 grading was predictive of segmental stability and numeric rating scale (NRS) leg pain improvement at 1 year postoperatively. Oswestry Disability Index and NRS back and leg pain scores all improved similarly in both cohorts at 1 year postoperatively.

CONCLUSIONS

Activated Ti interbody cages mediate early fusion at significantly higher rates with lower rates of subsidence as compared with PEEK cages. These findings support the idea that interbody cage microscale properties, including surface topography, may play a primary role in facilitating osseointegration and fusion.

The purpose of this study is to identify the potential and characteristics of MSMEs in Warung Tegal and to analyze internal and external factors as a business strategy for dealing with inflation. The data was analyzed using the strengths, weaknesses, opportunities, and threats (SWOT) method. MSMEs of Warung Tegal has the same characteristics in production, marketing, human resources, finance, law, and support from related agencies. In addition, its production uses a manual process, Warung Tegal sells its products through offline stores directly with 2-10 employees. Capital is relatively low and some MSME units of Warung Tegal have legality and well-managed management. Local governments play an important role in developing MSMEs in the face of inflation. Its main strength is the local supply of raw materials and the strategic location of the business, and the main drawback is the limited labor ability due to lack of training. The main opportunity is the trend of high public demand and open business partnerships, but they also face fierce competition as the main threat. MSME strategies in dealing with inflation include increasing cooperation to maintain the continuity of raw materials between regions, developing MSME service innovations, and increasing the role of local governments.

Quality service plays an important role in shaping customer satisfaction, but it is also closely related to creating profits for the company. The purpose of the study is whether service quality affects customer satisfaction, whether price affects customer satisfaction and whether service quality and price affect customer satisfaction. The analysis method used is descriptive analysis and multiple linear regression. This research was conducted in relation to the context (implementation of service quality, price and customer satisfaction). In addition, the theoretical gap (detailed perspective on each dimension) left by previous research. The results showed that service quality and price affect customer satisfaction at Café Gartenhutte Trawas. Quality and price show a multiple correlation 0.809 which shows a strong relationship between the independent variable and the dependent variable. This research has implications for businesses that should use their websites to convey information and offer the best customer service to increase perceived value.
