Pirolisis Gelombang Mikro Biomassa Tandan Kosong Kelapa Sawit (TKKS): Pengaruh Massa Absorber KOH dan Katalis Zeolit Alam terhadap Energi Produk
No full textThis study aims to investigate the effect of the KOH/TKKS ratio on the energy content and composition of three-phase pyrolysis products, with a fixed zeolite mass of 10 g. The pyrolysis process was conducted using 100 g of empty fruit bunches (TKKS) at 450 °C with a residence time of 15 minutes. The evaluation covered pyrolysis performance (yields of biochar, bio-oil, and gas), biochar properties (proximate analysis and energy content), bio-oil (energy content), and gas (composition via GC-TCD and energy content). The results show that increasing the KOH ratio accelerated the attainment of the target temperature from approximately 17 minutes (ratio 2:4) to 10 minutes (ratio 4:4) and promoted a higher gas fraction while reducing the bio-oil yield. The optimal condition for bio-oil production was achieved at a KOH/TKKS ratio of 2:4, yielding the highest bio-oil fraction of 29.3%. A higher KOH mass also increased the concentrations of CO, CO₂, and H₂ in the gas phase while decreasing the fixed carbon content in the biochar. The energy input during pyrolysis decreased significantly from 1513.11 kJ at the 2:4 KOH/TKKS ratio to 813.8 kJ at the 4:4 ratio, primarily due to the accelerated heating rate induced by higher KOH content. Despite this, the 2:4 ratio exhibited the highest energy conversion efficiency, as it produced the largest yield and energy content of bio-oil, contributing to a higher total energy output. These findings highlight the critical role of an appropriate KOH ratio in optimizing product distribution and energy efficiency in the pyrolysis process. The results underscore the potential of TKKS as a renewable energy source through microwave-assisted pyrolysis.Penelitian ini difokuskan pada pengaruh massa kalium hidroksida (KOH) sebagai absorber gelombang mikro terhadap performa proses pirolisis dengan massa zeolit 10 gram. Tahapan penelitian meliputi proses pirolisis tandan kosong kelapa sawit (TKKS) menggunakan gelombang mikro pada suhu 450 °C, kemudian dilakukan karakterisasi produk yang dihasilkan, yaitu biochar, bio-oil, dan gas. Hasil menunjukkan bahwa peningkatan massa KOH mempercepat pencapaian suhu target, meningkatkan produksi gas, menurunkan jumlah biochar, serta mengoptimalkan produksi bio-oil pada rasio KOH/TKKS sebesar 2:4. Penambahan massa KOH juga meningkatkan kandungan gas CO, CO₂, dan H₂, namun menurunkan kandungan volatile matter dan fixed carbon pada biochar. Evaluasi keseimbangan energi menunjukkan bahwa konsumsi energi menurun seiring bertambahnya massa KOH. Penelitian ini membuktikan bahwa pengaturan massa KOH berpengaruh signifikan terhadap distribusi produk dan efisiensi energi, serta memiliki prospek aplikasi dalam pengembangan energi berbasis biomassa limbah
Kajian teori kultivasi: Implikasi konten Boys’ Love terhadap kehidupan pribadi dan sosial Kaum Fujoshi dan Fudanshi di Indonesia
No full textThis study examines the implications of boys' love (BL) content on fujoshi and fudanshi in Indonesia who live amidst social and cultural values that oppose all LGBT activities. Specifically, this study aims to discover two things: the implications of BL content on the personal and social lives of fujoshi and fudanshi. This study uses a qualitative approach to produce data in descriptive form. Data were obtained using semi-structured interviews, participant observation, and document studies. The subjects in the study were fujoshi and fudanshi in various regions in Indonesia. The purposive sampling technique was used to obtain informant data. Inclusion criteria included heterosexual fujoshi and fudanshi as well as initially heterosexual fujoshi and fudanshi. After that, the data were transcribed verbatim and processed using data source triangulation techniques. The results of the study show several things. First, in personal life, BL content can foster homosexual tolerance for fujoshi and fudanshi. However, there is still an inner conflict with the social values and beliefs of fujoshi and fudanshi related to the view that LGBT activities are deviant. In addition, BL content can also make fujoshi and fudanshi better understand their sexual orientation. It can foster fujoshi and fudanshi sexual imagination which is contrary to the biological conditions of fujoshi and fudanshi in real life. Second, based on cultivation theory, BL content can cause changes in fujoshi and fudanshi social relations to a wider realm through the community. However, this can eventually lead to conflict between communities due to having different tensions.Penelitian ini mengkaji implikasi konten boys’ love (BL) terhadap fujoshi dan fudanshi di Indonesia yang notabenenya hidup di tengah nilai-nilai sosial dan budaya masyarakat yang menentang segala aktivitas LGBT. Secara spesifik, penelitian ini bertujuan untuk mengetahui dua hal, yakni implikasi konten BL terhadap kehidupan pribadi dan sosial fujoshi dan fudanshi. Penelitian ini menggunakan pendekatan kualitatif untuk menghasilkan data dalam bentuk deskriptif. Data diperoleh dengan metode wawancara semi-struktural, observasi partisipan, dan studi dokumen. Subjek dalam penelitian adalah fujoshi dan fudanshi di berbagai wilayah di Indonesia. Teknik yang digunakan dalam memperoleh data informan adalah teknik purposive sampling. Kriteria inklusi meliputi fujoshi dan fudanshi heteroseksual serta fujoshi dan fudanshi yang awalnya heteroseksual. Setelah itu, data ditranskripsikan secara verbatim dan diolah menggunakan teknik triangulasi sumber data. Hasil penelitian menunjukkan beberapa hal. Pertama, dalam kehidupan pribadi, konten BL dapat menumbuhkan toleransi homoseksual bagi fujoshi dan fudanshi. Meskipun di dalamnya masih ada pertentangan batin dengan nilai-nilai sosial dan kepercayaan fujoshi dan fudanshi terkait dengan pandangan bahwa aktivitas LGBT adalah menyimpang. Selain itu, konten BL juga dapat membuat fujoshi dan fudanshi lebih memahami orientasi seksualnya sendiri, serta dapat menumbuhkan imajinasi seksual fujoshi dan fudanshi yang sebenarnya bertolak belakang dengan kondisi biologis di kehidupan nyata. Kedua, berdasarkan teori kultivasi, konten BL dapat menyebabkan terjadinya perubahan hubungan sosial fujoshi dan fudanshi ke ranah yang lebih luas melalui komunitas. Meskipun di antaranya dapat menimbulkan konflik antar komunitas akibat memiliki tegangan yang berbeda

Double burden, ketimpangan gender, dan produktivitas kerja perempuan pemulung di Komunitas Pemulung Pasir Panjang Kota Kupang
No full textScavenging has been the object of scientific and academic research based on various scientific viewpoints worldwide. Still, the issue of the double burden that is experienced by women scavengers and its impact on gender inequality and women's productivity has received less attention. This research aims to explore further the effects of double burden or dual responsibility burdened by women scavengers in Komunitas Pemulung Pasir Panjang Kota Kupang, East Nusa Tenggara (NTT), to gender inequality and the productivity of women scavengers in that community. This research employed a qualitative approach including field observation and in-depth interviews. This research has found that the phenomena of double burden does not liberate women scavengers from the patriarchal chain that binds and restrains them, but instead makes them increasingly dependent on men in the economic and financial dimension of household life. In addition, they are caught in a dilemma between maximizing the option of working outside the home or taking care of their domestic work. As a consequence of the long-standing and strong internalization of a false awareness about women's natural duties, those women scavengers do not think of this as an injustice but rather an obligation that must be carried out properly and consistently.Pemulungan telah menjadi objek kajian penelitian ilmiah dari berbagai sudut pandang ilmu di seluruh dunia, tetapi isu double burden perempuan pemulung dan ketimpangan gender serta pengaruhnya bagi produktivitas perempuan kurang mendapat perhatian. Penelitian ini bertujuan untuk memperlihatkan pengaruh double burden atau dual responsibility yang dipikul oleh para perempuan pemulung di Komunitas Pemulung Pasir Panjang Kota Kupang, Nusa Tenggara Timur (NTT) bagi ketimpangan gender dan produktivitas perempuan pemulung di komunitas tersebut. Penelitian ini menggunakan pendekatan kualitatif meliputi observasi lapangan dan wawancara mendalam. Penelitian ini menemukan bahwa double burden tidak membebaskan perempuan pemulung dari lingkaran patriarki yang membelenggu mereka, tetapi justru membuat mereka semakin bergantung pada laki-laki. Selain itu, mereka berada dalam tekanan dilematis antara memaksimalkan pilihan bekerja di luar rumah atau mengurus pekerjaan domestik. Akibat internalisasi kesadaran palsu tentang kewajiban kodrati perempuan yang berlangsung lama, para perempuan pemulung di komunitas ini tidak merasa hal itu sebagai sebuah ketidakadilan melainkan tugas yang harus diemban sebagaimana mestinya

Error analysis of mathematics students in solving mathematical finance problems
No full textMathematical Finance is a course in the Mathematics Study Program. This course is highly useful in both the workplace and everyday life. However, the results of the student’s final exams (UAS) show unsatisfactory outcomes. This research is a descriptive qualitative study that aims to identify the types of errors in students' answers when solving Financial Mathematics final exams. The subjects of this research are students in the even semester of the Mathematics study program at Universitas Samudra. The data collection technique in this research is a test. The results showed that the standard errors found in students' answers were concept errors, namely errors due to students not understanding the concept, as well as procedural errors, which occurred when students had difficulty in linking concepts to the steps of the process. Additionally, there is a slip error that occurs when students are in a hurry to solve the problem, although this error is not dominant. This study concludes that a lack of conceptual understanding and procedural mainly causes students difficulties in Mathematical Finance. These findings contribute to the development of effective learning strategies and the creation of teaching materials by emphasizing the importance of understanding concepts and procedures in problem-solving

No full textThis study aims to analyze the effect of relative advantage and Electronic Word of Mouth (E-WOM) on consumer attitudes in online shopping with trust as a mediating variable. Given the rapid growth of e-commerce in Indonesia, understanding the factors that shape consumer trust and purchasing decisions is crucial for businesses and policymakers. This study uses a quantitative approach with a descriptive survey method. Data was collected through an online questionnaire from 114 respondents selected using the purposive sampling technique. The research model was analyzed using Structural Equation Modeling (SEM) with SmartPLS 4 to test the direct relationship and mediation between variables. The results show that relative advantage and E-WOM have a positive and significant effect on consumer trust, which in turn affects their attitude towards online shopping. The role of trust mediation strengthens the relationship between these factors and consumer attitudes, emphasizing that trust is the main determinant in shaping consumers' positive perceptions of e-commerce transactions. The implications of the findings of this study provide theoretical insights into the mechanism of consumer trust in e-commerce as well as practical recommendations for businesses to improve product advantage and manage customer reviews effectively. In addition, policymakers are encouraged to implement stricter regulations related to transaction security, data protection, and consumer rights to create a more trusted digital market ecosystem. Further research is suggested to expand the scope of demographics and add other variables, such as risk perception and user experience, to gain a more comprehensive understanding of consumer behavior in e-commerce.Penelitian bertujuan untuk menganalisis pengaruh keunggulan relatif dan E-WOM terhadap sikap konsumen dalam belanja online di Indonesia.
