Abstract

Indonesia is one of tropical countries with high humidity which makes it possible for various plants and microorganisms to grow properly. One of the microorganisms that shall grow well in Indonesia is be considered as fungi or mushrooms. They have several types including poisonous and edible mushrooms that shall be consumed by human beings. The purpose of this research is to make it easier to classify between the types of poisonous mushrooms and edible mushrooms which can be consumed by using the Naïve Bayes algorithm to get the accurate classification results. In this research, the Naive Bayes algorithm is used to classify the types of mushrooms by utilizing the Principal Component Analyst technique which serves to reduce the number of features applied in the dataset. The data collection technique used in the research is by documenting the official website of the UCI Machine Learning Repository whereas the Mushrooms dataset consists of 22 features and 1 class are applied. After classifying using Naïve Bayes with Principal Component Analyst, then the researcher is evaluating using the 10-Fold Cross Validation technique whereas the results obtained are pc = 10 and the classification result is be considered as 84%.

Abstract

This study aims to examine the influence of digital promotion, product quality, product prices, and business location on purchasing decisions for products produced by micro, small, and medium enterprises (MSMEs) in Pabean Udik village, Indramayu district. Pabean Udik village is located in a coastal area with relatively low levels of education and technological literacy. The study population includes MSME actors, community members, and stakeholders in the village. The measurement scale used is a Likert scale. If the model includes intervening or moderating variables, it can be analyzed using path analysis. Path analysis allows for the examination of direct and indirect relationships between variables. The analysis will help in making decisions based on hypothesis testing. The findings show that product quality has a positive effect on purchase decisions, product price does not significantly influence purchase decisions, digital promotion has a positive effect on purchase decisions, and business location does not significantly influence purchase decisions. Additionally, product quality, through business location, has a positive effect on purchase decisions, and product price, through digital promotion, also has a positive effect on purchase decisions. Digital promotion has the strongest influence on customers' purchasing decisions. To enhance the competitiveness of MSMEs in coastal areas, it is recommended to utilize digital promotions through platforms such as WhatsApp and Facebook. Additionally, programs for improving the digital literacy and skills of MSMEs' human resources are recommended to better adapt to social media and digital platforms. The aim is to increase their positive competitiveness in the market.

Untuk mengatasi masalah ini, kegiatan Pengabdian Kepada Masyarakat ini bertujuan untuk memberikan solusi yang dapat meningkatkan aspek legalitas Pelaku Usaha. Kegiatan ini menggunakan metode  Participatory Rural Appraisal (PRA) adalah metode partisipatif yang digunakan untuk mengumpulkan informasi dan memahami kondisi sosial, ekonomi, dan lingkungan Masyarakat. Tahapan kegiatan yang dilaksanakan dimulai dari survei mitra, identifikasi permasalahan mitra, dan dilanjutkan dengan tahap pendampingan mitra. Hasil pengabdian kepada masyarakat menunjukkan bahwa adanya pendampingan terkait pendaftaran Perseroan Perorangan ini memberikan pengetahuan serta keterampilan guna memberikan kepastian hukum bagi Pelaku Usaha untuk meningkatkan perekonomian dengan bekerja sama dengan pihak-pihak lain yang berkepentingan. Dengan adanya Perseroan Perorangan diharapkan mampu untuk mendorong UMKM menjadi usaha yang berdaya saing global karena dapat meningkatkan kepercayaan diri pelaku usaha untuk dapat semakin maju dan berkembang secara Nasional maupun Internasional. Dengan dilaksanakannya kegiatan pengabdian kepada masyarakat ini, Pelaku Usaha telah terdaftar sebagai Perseroan Perorangan sebagaimana terdaftar pada Kementerian Hukum dan Hak Asasi Manusia Republik Indonesia. Beberapa kelebihan perseroan perorangan yaitu dapat bersaing dengan Perseroan Terbatas pada umumnya, cocok untuk usaha mikro dan kecil, yang masih pemula serta mau mengembangkan usaha sendiri. Selanjutnya, pelaku usaha bertindak sebagai direktur, terakhir bahwa status badan hukum diperoleh setelah mendaftarkan pernyataan pendirian secara online. Kata kunci: legalitas usaha; pelaku usaha; perseroan perorangan; UMKM. Abstract The absence of legality in running a business can cause problems. Legality is needed to guarantee that a Business Actor carries out his business with full responsibility and has been registered with the Ministry in charge of MSMEs. To overcome this problem, this Community Service activity aims to provide solutions that can improve the legality aspects of Business Actors. This activity uses the Participatory Rural Appraisal (PRA) method, which is a participatory method used to collect information and understand the social, economic and environmental conditions of society. The stages of activities carried out start from partner surveys, identification of partner problems, and continue with the partner mentoring stage. The results of community service show that the assistance related to the registration of Individual Companies provides knowledge and skills to provide legal certainty for Business Actors to improve the economy by collaborating with other interested parties. With the existence of Individual Companies, it is hoped that it will be able to encourage MSMEs to become globally competitive businesses because it can increase the self-confidence of business actors to be able to progress and develop nationally and internationally.

Next, the business actor acts as a director, finally the legal entity status is obtained after registering the statement of establishment online. Keywords: business legality; business actors; individual companies; MSMEs.

Abstract

Analisis sentimen pada dataset berukuran kecil sering menghadapi masalah ketidakseimbangan kelas yang dapat menurunkan performa klasifikasi. Berbagai teknik penanganan seperti Synthetic Minority Oversampling Technique (SMOTE) dan Random Under Sampling (RUS) telah digunakan untuk meningkatkan performa, tapi aspek stabilitas model masih relatif jarang diperhatikan. Penelitian ini bertujuan untuk menganalisis performa dan stabilitas model klasifikasi sentimen pada dataset ulasan wisata berbahasa Indonesia yang berukuran kecil dan tidak seimbang. Selain itu, penelitian ini mengintegrasikan metrik stabilitas, yaitu Stability Sensitivity Index (SSI) dan Relative Robustness Score (RRS), yang masih jarang dieksplorasi dalam klasifikasi sentimen berbahasa Indonesia. Model yang digunakan adalah Logistic Regression dengan representasi fitur TF-IDF. Eksperimen dilakukan menggunakan tiga skenario, yaitu tanpa balancing, SMOTE, dan RUS, serta dievaluasi menggunakan 5-fold cross-validation. Hasil menunjukkan bahwa SMOTE menghasilkan F1-score tertinggi sebesar 0.926, sedangkan metode RUS memiliki stabilitas terbaik dengan standar deviasi terendah dan nilai RRS tertinggi. Temuan ini menunjukkan adanya trade-off antara performa dan stabilitas, di mana model dengan performa terbaik tidak selalu paling stabil. Penelitian ini memberikan kerangka evaluasi yang lebih komprehensif untuk klasifikasi sentimen pada dataset kecil dan tidak seimbang.
