Abstract

Optimization is the search for the optimal value of a problem with the help of one or more objective functions. Optimization problems are often found in everyday life and become important in the operation of a production system. The simplest optimization problem in the industrial world is solved using linear programming. Linear programming equations are made to solve optimization problems in the industrial world. In optimizing a problem, computational tools are needed to produce the optimal solution. Many computational tools are used, one of which is Excel Solver. Excel Solver is operated because many Microsoft Office users have this computing tool. Where everyone commonly uses Excel. The world of industrial Engineering needs someone who can solve optimization problems, especially since the current industrial era is getting more advanced. More skills are necessary for dealing with the Industrial Revolution 4.0 and Society 5.0, and it becomes a mandatory ability for an industrial engineer to solve this problem. Therefore, this community service activity is proposed with the topic: "Technique for Calling Millennials (TMKM) for Optimization Modules using Linear Programming with Excel Solver" to introduce optimization in the industrial world using existing optimization techniques and simple tools needed as applications in industrial engineering science. This community service activity was carried out in collaboration with Citra Blessing Tangerang High School. This activity is given to all students and teachers at SMA Citra Blessing Tangerang. The target audience for this activity is 50 participants. It is hoped that this activity can provide knowledge in the field of optimization and also provide an overview of industrial developments in the Industrial Revolution 4.0 era and in Society 5.0. Besides that, it also opens students' insights about the field of Industrial Engineering, especially opening students' insights about career prospects in the Industrial Engineering field.

Abstract

Kehadiran restoran cepat saji telah mempengaruhi pola makan masyarakat khususnya perkotaan karena ketersediaannya yang mudah dan variasinya. Penelitian ini bertujuan menganalisis preferensi konsumen terhadap restoran cepat saji di Indonesia dengan menggunakan analisis sentimen dan emosi berbasis aspek. Data penelitian diperoleh dari ulasan Google Review dan kuesioner dari 100 responden. Proses analisis meliputi pembersihan data, pembobotan TF-IDF, dan pemisahan data menjadi set pelatihan dan pengujian. Analisis sentimen berbasis aspek digunakan untuk mengidentifikasi sentimen positif dan negatif berbagai aspek layanan, sementara analisis emosi untuk mengukur jenis dan tingkat emosi pelanggan berdasarkan sentimen yang terdeteksi. Hasil visualisasi menunjukkan berbagai sentimen dan emosi yang terkait dengan setiap aspek atribut layanan restoran. Model Importance Performance Analysis (IPA) tiga dimensi digunakan untuk mengevaluasi hubungan antara tingkat kepentingan dan kepuasan hasil sentimen dan emosi pelanggan. Hasil analisis sentimen berbasis aspek menunjukkan bahwa sebagian besar restoran mendapat sentimen positif pada semua aspek. Pada hasil analisis emosi terlihat bahwa pada setiap sentimen positif akan selaras dengan emosi yang positif dan begitu sebaliknya. Temuan dalam penelitian ini diharapkan dapat memberikan wawasan berharga bagi para pengelola restoran untuk meningkatkan pengalaman pelanggan melalui pemahaman mendalam tentang sentimen dan emosi pelanggan.   Abstract The presence of fast food restaurants has influenced people's diets, especially in urban areas, due to their readily availability and variety. This study aims to analyze consumer preferences for fast food restaurants in Indonesia using aspect-based sentiment and emotion analysis. The research data was obtained from Google reviews and questionnaires distributed to 100 respondents. The analysis process includes data cleaning, TF-IDF weighting, and data separation into training and testing sets. Aspect-based sentiment analysis was used to identify positive and negative sentiments on various aspects of the service, while emotion analysis was applied to measure the types and levels of customer emotions based on the detected sentiments. The visualization results show the various sentiments and emotions associated with each aspect of the restaurant's service attributes. In addition, this study used a three-dimensional Importance Performance Analysis (IPA) model to evaluate the relationship between importance and satisfaction levels based on customer sentiments and emotions.  The results of aspect-based sentiment analysis show that most restaurants get positive sentiments on all aspects. The emotion analysis results demonstrate a correlation between any positive sentiment and positive emotions, and vice versa. The findings in this study are expected to provide valuable insights for restaurant managers to improve customer experience through an in-depth understanding of customer sentiments and emotions.

Abstract

Using earphones or earbuds while driving positively and negatively impacts the driver. Congestion is a condition that causes motorists to use these hearing aids. However, the use of hearing aids while driving can threaten the safety of drivers and other drivers. The Bumi Serpong Damai (BSD) area is an area with many motorcyclists, so it can be a reference for motorists to pay attention to the dangers of using earphones while driving. Using earphones while driving, motorcyclists often do not focus on road conditions. Moreover, motorists can be indifferent to signs and other motorists. Therefore, a study was conducted on the use of hearing aids by two-wheeled riders in the BSD area to reveal the underlying problems associated with the use of hearing aids when driving. This study was conducted through the distribution of questionnaires and data processing using the chi-square test and logistic regression. This study aimed to determine motorcyclists’ level of awareness about the dangers of using earphones while driving. The result showed that a relationship exists between the frequency of use and driving comfort; the dominant factor affected by using hearing aids while driving is a reduction in emotions due to traffic jams. This study recommends that the government address traffic congestion due to its strong impact on driver emotions. For motorcyclists, it is advised to keep the earphone volume low to maintain focus on traffic signs and surrounding sounds.

Abstract

Program Pengabdian kepada Masyarakat (PkM) ini berangkat dari rendahnya pemahaman masyarakat tentang manfaat tempe, meskipun tempe merupakan makanan tradisional Indonesia yang kaya gizi dan bernilai ekonomi. Sejak 2023, Fakultas Biosains, Teknologi, dan Inovasi (FBTI) serta Pusat Penelitian & Pengembangan Tempe (P3T) Unika Atma Jaya bekerja sama dengan Kampung Tempe Ciomas untuk mendorong inovasi pengolahan tempe. Tujuan utama kegiatan adalah meningkatkan pengetahuan dan keterampilan ibu-ibu WKRI (Wanita Katolik Republik Indonesia) Ranting Pangkalan Jati dalam memproduksi tempe sehat sekaligus memperluas pengenalan Kampung Tempe Ciomas agar penjualan produknya meningkat. Pelaksanaan program dilakukan melalui kolaborasi dosen dan mahasiswa dengan mitra. Workshop interaktif menjadi metode utama, di mana peserta dilibatkan langsung dalam praktik pembuatan tempe, didukung demonstrasi, diskusi, dan tanya jawab. Hasil evaluasi melalui kuesioner pre-test dan post-test menunjukkan peningkatan signifikan pemahaman peserta, meliputi mikroba fermentasi, manfaat gizi, hingga sejarah tempe. Analisis deskriptif memperkuat bahwa kegiatan ini efektif dalam menambah wawasan. Luaran program mencakup laporan, dokumentasi video yang dipublikasikan di Instagram Kampung Tempe Ciomas, serta artikel jurnal untuk mendukung keberlanjutan. Dokumentasi ini sekaligus berfungsi sebagai sarana promosi dan edukasi masyarakat. Dengan demikian, kegiatan ini diharapkan memberi dampak positif terhadap peningkatan gizi keluarga dan pendapatan masyarakat secara berkelanjutan.
