Judul: Green Consumption Behavior of Indonesian Young Consumers: The  Role of Knowledge, Responsibilities, and Attitudes towards the Environment
Abstrak: Konsumsi merupakan salah satu penyebab masalah lingkungan yang harus segera diatasi. Konsumen sebagai pelaku utama kegiatan konsumsi memiliki tanggung jawab utama dalam aksi penyelamatan lingkungan. Tujuan penelitian ini adalah untuk menganalisis pengaruh pengetahuan lingkungan, tanggung jawab lingkungan, dan sikap lingkungan terhadap perilaku konsumsi hijau di kalangan konsumen muda Indonesia. Penelitian ini menggunakan mix methods dengan metode pengumpulan data berupa survei online¸ wawancara mendalam, dan observasi. Sebanyak 328 responden terlibat sebagai contoh dalam penelitian menggunakan teknik voluntary sampling. Analisis data dilakukan secara deskriptif dan SEM menggunakan bantuan aplikasi SPSS 25.0 dan LISREL 8.80. Hasil penelitian ini menunjukkan pengaruh yang positif signifikan pengetahuan lingkungan terhadap tanggung jawab lingkungan, sikap lingkungan, dan perilaku konsumsi hijau. Tanggung jawab lingkungan berpengaruh positif signifikan terhadap sikap lingkungan. Sikap lingkungan berpengaruh positif signifikan perilaku konsumsi hijau. Pengetahuan, tanggung jawab lingkungan, dan perilaku konsumsi hijau konsumen muda Indonesia berada pada kategori sedang sedangkan sikap lingkungan berada pada kategori tinggi. Dengan demikian perlu peningkatan pengetahuan dan tanggung jawab konsumen terhadap lingkungan untuk mendorong peningkatan perilaku konsumsi hijau., Consumption is one of the causes of environmental problems that must be addressed immediately. Consumers as the main actors in consumption activities have the main responsibility in environmental saving actions. The purpose of this study was to analyze the effect of environmental knowledge, environmental responsibility, and environmental attitudes on green consumption behavior among young Indonesian consumers. This study uses mixed methods with data collection methods in the form of online surveys, in-depth interviews, and observations. A total of 328 respondents were involved as a sample in the study using voluntary sampling technique. Data analysis was carried out descriptively and SEM using SPSS 25.0 and LISREL 8.80. The results of this study indicate a significant positive effect of environmental knowledge on environmental responsibility, environmental attitudes, and green consumption behavior. Environmental responsibility has a significant positive effect on environmental attitudes. Environmental attitudes have a significant positive effect on green consumption behavior. Knowledge, environmental responsibility, and green consumption behavior of young Indonesian consumers are in the medium category while environmental attitudes are in the high category. Thus, it is necessary to increase consumer knowledge and responsibility towards the environment to encourage an increase in green consumption behavior.

Judul: Analysis of Perceptions Analysis and Factors Affecting the Implementation of Green Consumption Behavior in Little Talk Coffee Shop Consumers
Abstrak: Meningkatnya model bisnis indsutri pangan di Indonesia yang perlu didisrupsi dengan menghadirkan inovasi yang lebih ramah lingkungan seperti substitusi bahan kemasan yang tidak ramah lingkungan. Konsumen bijak sebelum melakukan pembelian suatu produk akan memikirkan terlebih dahulu dampak dari produk yang dikonsumsinya. Penelitian ini bertujuan untuk mengdentifikasi persepsi konsumen (generasi Z) terhadap produk hijau yang disajikan di kedai kopi Little Talk dan menganalisis pengaruh pengetahuan lingkungan, sikap lingkungan dan produk hijau terhadap penerapan perilaku konsumsi hijau ketika mengunjungi kedai kopi Little Talk. Metode analisis data yang digunakan dalam penelitian ini adalah analisis deskriptif kuantitatif dengan skala likert dan Structural Equation Modeling - Partial Least Square (SEM-PLS) dengan bantuan software SmartPLS4. Hasil penelitian menunjukkan konsumen (generasi Z) setuju dengan produk hijau yang disajikan oleh kedai kopi Little Talk. Berdasarkan hasil pengujian hipotesis sikap lingkungan berpengaruh signifikan terhadap produk hijau dan perilaku konsumsi hijau, sedangkan pengetahuan lingkungan tidak berpengaruh signifikan terhadap sikap lingkungan, produk hijau, dan perilaku konsumsi hijau. Dengan demikian perlu peningkatan pengetahuan konsumen (generasi Z) terhadap lingkungan untuk mendorong peningkatan perilaku konsumsi hijau., The increasing business model of the food industry in Indonesia needs to be disrupted by presenting more environmentally friendly innovations such as substituting packaging materials that are not environmentally friendly. Wise consumers before purchasing a product will first think about the impact of the products they consume. This study aims to identify consumer perceptions (generation Z) of green products served at Little Talk coffee shops and analyze the influence of environmental knowledge, environmental attitudes and green products on the application of green consumption behavior when visiting Little Talk coffee shops. The data analysis method used in this research is quantitative descriptive analysis with a Likert scale and Structural Equation Modeling - Partial Least Square (SEM-PLS) with the help of SmartPLS4 software. The results showed that consumers (generation Z) agree with the green products served by Little Talk coffee shops. Based on the results of hypothesis testing, environmental attitudes have a significant effect on green products and green consumption behavior, while environmental knowledge has no significant effect on environmental attitudes, green products, and green consumption behavior. Thus, it is necessary to increase consumer (generation Z) knowledge of the environment to encourage increased green consumption behavior.

Judul: Penyusunan Overlap Graph menggunakan Suffix Tree pada DNA Sequence
Abstrak: The DNA sequence assembly is very important in genome analysis. This step aims to reconstruct contigous DNA fragment (contigs) from short fragment by concatenating fragments based on the overlap region among them. This method employs overlap graph for solving the problems. In this graph, nodes represent fragments and edges represent overlap. This research developed a software for constructing overlap graph using suffix tree. The evaluation was conducted by measuring the number of nodes, number of edges, and the execution time in many values of minimum overlap. The minimum overlap is defined as the minimum length of substring which is considered as the overlap region between two fragments. The evaluation results showed that the number of nodes, the number of edges, and the execution time were increased with the decreasing of the minimum overlap value.
