Sweden maintained its neutrality in response to its history, including during the Napoleonic wars, by adopting “neutrality” as its official policy in 1834. This neutrality was upheld during both World Wars to protect trade interests. During the Cold War, Sweden chose the path of peaceful diplomacy and rejected military alliances. But Sweden experienced concerns over the Russia-Ukraine conflict and Russia's intervention in Crimea. In May 2022, Sweden eventually applied for NATO membership in response to Russia's invasion of Ukraine in February 2022. This research aims to understand the reasons behind Sweden's decision to join NATO. The factors behind Sweden's decision to join NATO are analyzed using qualitative research methods and through the lens of Threat Perception concept. This research discusses the factors behind Sweden’s decision to join NATO through five dimensions from the Threat Perception concept: structural, geopolitical, historical, socio-cultural, and economic. This research indicates that these five dimensions influenced Sweden's decision to join NATO. Firstly, Swedish ministers and political parties in Sweden played a role in the decision-making process. Secondly, Sweden's geographical location and the rising activities in the Baltic Sea also influenced its decision. Thirdly, Sweden's historical relationship with NATO compared to its relationship with Russia also influenced the decision. Fourthly, the ethnic, cultural, and religious composition of people in Sweden, along with policymaker adoption, are believed to have played a significant role in Sweden's foreign policy formation. Finally, the economic benefits of joining NATO were also considered by Sweden.Swedia telah menjaga netralitas sebagai respons terhadap sejarahnya, termasuk perang Napoleon, dengan mengadopsi kebijakan resmi pada tahun 1834. Netralitas ini dipertahankan selama kedua Perang Dunia untuk melindungi kepentingan perdagangan. Selama Perang Dingin, Swedia memilih jalur diplomasi damai dan menolak aliansi militer. Namun, Swedia mengalami kekhawatiran atas konflik Rusia-Ukraina dan intervensi Rusia di Crimea. Pada tahun 2022, Swedia akhirnya mengajukan keanggotaan NATO sebagai respons atas invasi Rusia ke Ukraina pada bulan Februari 2022. Penelitian ini bertujuan untuk memahami alasan di balik keputusan Swedia untuk bergabung dengan NATO. Faktor-faktor yang mendorong keputusan Swedia untuk bergabung dengan NATO dianalisis menggunakan metode penelitian kualitatif dan melalui lensa konsep “persepsi ancaman”. Studi ini membahas faktor-faktor tersebut melalui lima dimensi: struktural, geopolitik, sejarah, sosial-budaya, dan ekonomi. Temuan penelitian menunjukkan bahwa kelima dimensi tersebut memengaruhi keputusan Swedia untuk bergabung dengan NATO. Pertama, Menteri dan partai politik di Swedia berperan dalam proses pengambilan keputusan Swedia bergabung dengan NATO. Kedua, lokasi geografis Swedia dan aktivitasnya di Laut Baltik juga memengaruhi keputusan tersebut. Ketiga, hubungan historis Swedia dengan NATO dibandingkan dengan hubungannya dengan Rusia juga memengaruhi keputusan tersebut. Keempat, komposisi etnis, budaya, dan agama di Swedia, bersama dengan adopsi kebijakan oleh pembuat kebijakan, diyakini memainkan peran penting dalam pembentukan kebijakan luar negeri Swedia. Terakhir, manfaat ekonomi dari bergabung dengan NATO juga dipertimbangkan oleh Swedia.

PT. Pebana Adi Sarana targets monthly production operations of 20,000 tons/month while actual production is only around 15,000 tons/month, which means that the production target has not been achieved. The factors that cause the failure to achieve the production operation target can be due to ineffective equipment performance, Low equipment performance is one of the things that cause production not to be achieved, so it needs to be studied. The purpose of the study to be achieved is to analyze the actual productivity of loading and unloading equipment and transportation equipment after repairs and conduct improvement analysis using the Quality Control Circle (QCC) method. The data taken for the research is in the form of Excavator and dump truck cycle time data, effective working time, tool specifications. The actual productivity of loading and unloading equipment and transportation equipment at PT. Pebana Adi Sarana for dump trucks of 19,146 tons/month. trucks are 16,351 tons/month while for the Quality Control Circle (QCC) method. The company only needs to carry out the number of tools needed for 3 units of Scania p380 dump trucks and 1 unit of komatsu PC 300 excavator with a production of 21,295 tons/month has exceeded the production target set by the company.

In today’s era, social media has become a driving force for increasing digital entrepreneurship. Businesses are utilizing social media sites such as Instagram, TikTok, LinkedIn, or even Facebook to brand their companies or products and interact with clients. This is great news for businesses, especially SMEs, to have low-cost access to key markets worldwide. One evident trend is the emergence of social commerce – business-to-consumer commerce without intermediaries, exclusive of other e-commerce models. However, the adoption of social media in digital entrepreneurship comes with several challenges, such as changes in algorithms that can affect content visibility and risks related to data security and user privacy. Nevertheless, social media remains useful in terms of analytics to support strategic decisions. This study shows the value of social media for entrepreneurship and technologies that help improve content personalization and consumer behavior analysis, such as artificial intelligence and big data. This study attempts to fill the gap in the literature by looking at the differences in the outcomes of social media use in developing and developed countries and the outcomes of new technologies on digital business ventures.
