This Habit is Hard to Break: How to Incorporate Different Voices in STEM Information Literacy
Authors: Weaver Kari , Mercer Kate , Mutch Stephanie
Published: March 2024

This paper explores the connection between critical theory, information evaluation, and the instructional practice of critique for STEM students and librarian instructors. Using an emerging theory and instructional method, the authors examine how to more deeply include voices that have historically been excluded from STEM information critique. The foundational ideas, pedagogical approaches, and scaffolded curriculum used to engender a more inclusive approach to information within third- and fourth-year engineering design classes are discussed to contextualize the application of theory to the practical setting. Rooted in critical theory, this case considers how student information behaviors can ultimately perpetuate or subvert social structures and expectations.
Stop, Collaborate, and List ‘Em: Creating Local Metadata to Promote User Discovery of Minoritized Identities in a STEM Collection
Authors: Dhyne Paige J. , Nance Alyssa
Published: March 2024

Historical and modern scientific thought is dominated by the English language, colonized science, patriarchal norms, and Westernized “ways of knowing.” By making materials that lie outside that narrative discoverable (e.g., non-Western science, Indigenous/Aboriginal knowledge, women in science, etc.) we can assert that science is a global endeavor by representing diverse scientists on physical library shelves or ebook “shelves.” The Cataloging and Metadata Librarian and Science and Outreach Librarian at Furman University, a small liberal arts college, collaborated on a project to address discriminatory practices in the catalog records of a subset of the libraries’ STEM collection. Spurred by another project to update deprecated Cutters in Library of Congress call numbers, we assessed collection content with an eye to improve future collection development and created a local method for collocating DEI materials within an Alma consortium catalog. The intended goals of the project were to update the collection, improve metadata to increase discoverability, and develop an auditing process to use for other collections.
“Why the Silence?”: Giving a Voice to the Lived Experiences of STEMM Librarians
Authors: Magid Amani , Torres Ana
Published: March 2024

Inclusion, diversity, belonging, and equity (IDBE) are tenets discussed and developed in many universities and university libraries. Although there were studies on IDBE in libraries in general, the authors of this study were particularly interested in what Science, Technology, Engineering, Mathematics and Medicine (STEMM) librarians were facing or not facing regarding IDBE. We were unable to locate any known study focusing on STEMM librarians' lived experiences regarding IDBE. Thus, our study aimed to explore this area further. A survey consisting of multiple-choice, Likert and short-answer questions was sent to STEMM librarians via specific listservs. In this study, we use a grounded theory approach and analyze three of the questions in the survey. This study would particularly interest librarians who would like to ascertain the climate of IDBE and the intersection with social justice in STEMM Librarianship. Also, we provide strategies to improve the climate and provide a more inclusive, diverse, equitable and belonging environment for STEMM Librarians. Our data analysis shows that STEMM librarians who identify as People of Color encounter negative behaviors, experiences, and attitudes at a much higher rate than STEMM librarians who are white. In addition, many STEMM librarians who identify as white report white privilege awareness.
Forgetting, Memory and the Problem of Identity in Modern Culture: The Case of 'Apples'
Authors: Tuğcu Muhammed Said
Published: March 2024

Bu makale bireysel ve toplumsal düzeyde unutma, unutmayla bağlantılı olarak hafıza ve kimlik(sizleşme) sorunlarına odaklanmaktadır. Unutmanın modern kültüre özgü yaşam biçimlerinden kaynaklandığı varsayımıyla hareket edilmektedir.
Herhangi bir şeyin "gösteri"lmedikçe anlam kazanamadığının düşünüldüğü modern yeni medya kültüründe bireylerin eylemleri yalnızca içi boşaltılan ve hızlıca unutulan seyirliklerden ibaret olmaktadır. Bu iç boşaltma ve anlamsızlaştırma
tarihe, geleneğe, hafızaya ve kimliğe de benzer yollarla sirayet etmektedir. Kimlik; farklılıkların ve ayırt edilebilir özelliklerin ifade edilebilmesi için kullanılan bir terimdir. Bir kişi ismiyle, kökeniyle (geçmişiyle/hafızasıyla)
diğerlerinden ayrılabilir. Tüm bunların unutulması, farklılıkların silinmesi ve yeni kimliğin ayırt edilebilir yanlarının olmaması bireyi ve toplumu önemli bir kimlik sorunuyla karşılaştırmaktadır. Apples filmi hafızasını ve kimliğini
kaybeden bir toplumun portresini çizmektedir. Bu makale; sosyolojik film analizi yöntemiyle Apples filmini analiz etmektedir. Modern kültürde unutma, hafıza ve kimlik sorunu üzerine tartışmalar yürütmektedir. Öncelikli olarak unutma
meselesi üzerine yoğunlaşmakta, ardından unutmayla ilişkilendirilen hafıza ve kimlik konularına yönelmektedir.
The Relationship between Sophos and Philosophos in Plato and ‘Prophet’ as the Subject of the Event
Authors: Celilzade Hayyam
Published: March 2024

Çalışmamızda Platon’un felsefesinde önemli yer tutan bilge ve filozof kavramlarını ele alacağız. Bu iki kavramı birbiriyle irtibatı açısından değerlendirerek, Platon’un felsefe tanımına ulaşacağız. Fikriyat tarihinde Platon’un felsefesini
ve bu itibarla da bilge ve filozof kavramlarını Fârâbî’nin nasıl ele aldığını sorunsallaştıracağız. Bu bağlamda Fârâbî’nin Platon okumasının ne kadar isabetli olduğunu sorgulayarak onun nübüvvet kuramının bilge ve filozof arasındaki
irtibatın mahiyetini yakalayıp yakalayamadığına cevap arayacağız. Daha sonra Platon’un filozof kavramıyla ilahi kelamın mübelliği olan nebi arasında ne gibi farklılıkların olduğu üzerinde durarak akademik dünyamızda neredeyse yer
edinmiş filozof ve nebi benzerliğinin yanlış olduğunu göstereceğiz. Bu yanlışın nereden kaynaklandığını irdeleyerek nebinin filozofla değil bilgeyle benzerliğinin kurulabileceğine vurgu yapacağız. Ancak bu benzerliğin aynılık olup
olmadığına, asıl tekilliğin ve asıl hadisenin bilgeyle mi yoksa nebiyle mi alakalı olduğu sorusuna verilecek cevap üzerinden ulaşacağız. Yani Platon’un bilgeye verdiği merkeziliği Fârâbî’nin nebiye verdiğini ileri sürmek mümkün
müdür? Fârâbî’nin felsefesinde nebi, siyaset sahnesini kuran ve bu anlamda toplumsallaşmayı sağlayan bir figür olmakla birlikte ontolojisini nebiyi merkeze alarak mı inşa etmiş? Platon’un sadece ontolojisini değil bütün bir metafizik
sistemini bilgeyi merkeze alarak geliştirdiğini dikkate alırsak, nebiyi esas alarak yeni bir metafizik sistemin geliştirilmesi Fârâbî’nin felsefesinin de içerilerek aşılması anlamına mı gelir? İşbu soruları yanıtlamaya çalışacak
olan çalışmamızın akademiye katkı sağlayacağı kanaatindeyiz.

In Durian Tibarau, West Pasaman, there are 6 Micro Hydro Power Plants (MHPP) with a total installed capacity of 234.5 kVA or 187.6 kW, 3 Phase, 400 V, 50 Hz. The 6 MHPP are adjacent to each operating location. For this reason, it is necessary to analyze the interconnection load flow of the MHPP system, to see the initial conditions of the voltage state, load flow and power losses. The formulation of the load flow equation is based on the power system of 6 MHPP buses, 6 load buses and 12 line, 400 Volt voltage. Completion of load flow analysis using the Adaptive Newton Raphson method with an iteration process and application of the Electrical Transient Analysis Program (ETAP) 12.6. The results of the load flow research show that the bus that is close to the generator is at nominal voltage while the bus that is far from the generator has a voltage drop. The biggest line power losses occur in the difference in bus voltage values â€‹â€‹from the sending side bus to the receiving side bus. The total power generated by MHPP is equal to the total consumer load plus the total line power losses.

Terdapat permasalahan yang sering dialami oleh petani ketika menjelang panen padi yaitu adanya hama burung. Burung biasanya memakan biji-biji padi yang menyebabkan hasil panen berkurang. Umumnya petani menggunakan cara tradisional untuk mengusir hama tersebut yaitu dengan membentangkan benang atau membuat kentongan dari kaleng bekas. Cara tradisional tersebut kurang efektif dikarenakan jangkauan suara yang dihasilkan terbatas, juga membutuhkan waktu dan tenaga para petani. Alat pengusir hama padi ini adalah alat yang menimbulkan gelombang ultrasonic dengan frekuensi 2,5 â€“ 60 kHz yang dapat diatur sesuai dengan frekuensi pendengaran burung pemakan padi. Selain itu juga dapat membangkitkan suara burung elang yang merupakan predator alami bagi burung. Catu daya diperoleh dari energi panas matahari melalui panel surya. Aktivitas kendali alat dilakukan secara otomatis berbasis microcontroller ATMEGA 328P dan Integrated Circuit Real Time Clock sehingga pengguna dapat menentukan rentang waktu penggunaan alat. Alat pengusir padi ini telah diuji di area persawahan masyarakat di Desa Pernek Kecamatan Moyo Hulu, Sumbawa.

Published: March 2024

The efficiency of the photovoltaic system is very low ranging from 9-17% in areas with low irradiation while the investment costs are quite high. In addition, the power output of the photovoltaic system is highly volatile due to changes in irradiation due to weather and cloud movement, and temperature change. This research proposes the MPPT method based on ANFIS in the photovoltaic system for transient behavior analysis and system efficiency improvement. The results of the proposed method were compared with the MPPT Perthub & Observe (P&O) method. Each MPPT method was applied to a boost converter connected to a photovoltaic module with a capacity of 150 Wp to adjust the duty cycle using Simulink simulation in MATLAB. The irradiation and temperature data for 3 consecutive days were from Saturday to Monday, September 4 to 6, 2021. The simulation results show that the transient time of ANFIS MPPT is 6.23 times faster than that of P&O MPPT. The efficiency of ANFIS-based MPPT is higher than MPPT P&O. At 917.3 W/m2 of irradiation, the output power of the boost converters are 132.09, and 111.69 Watt for the ANFIS-based MPPT controller, and the P&O method MPPT, respectively.

The Effect of Drying Time on the Antioxidant Properties of Single Black Garlic Powder
Authors: Sari Rika , Herdyastuti Nuniek
Published: March 2024

Black garlic is a processed product derived from fresh garlic that generally has a taste and aroma that is less preferred. A drying process is employed to increase the attractiveness of consuming black garlic. This study aims to assess the impact of the drying time on the antioxidant activity and content of antioxidant compounds such as phenolics, flavonoids, and tannins in single black garlic. The drying time is expected to yield a single black garlic powder that is more convenient for consumption, whether in capsule form or as an addition to food products. With low moisture content, single black garlic powder has a longer shelf life and high antioxidant activity, potentially commanding a higher market value. In this research, the drying time was carried out on a single black garlic using an oven for 6, 12, 18, and 24 hours. The analysis of the total phenolic content (TPC), entire tannin content (TTC), and total flavonoid content (TFC) was determined using a Uv-Vis spectrophotometer, and each component was measured concerning gallic acid equivalent for TPC, quercetin for TFC, and tannic acid for TTC. Antioxidant activity was determined using the DPPH method, and the outcomes were expressed as IC50 values. The research shows that the extended drying time leads to an augmentation of the antioxidant compound in black garlic. Drying for 24 hours produces significant outcomes, showing potent antioxidant activity with an IC50 value of 37,019 ppm (powerful antioxidant category), total phenolic content value is 44,785 ± 0,033 mgGAE/g, total flavonoid content value is 32,033 ± 0,008 mgQE/g, and total tannins content value is 74,884 ± 0,057 mgTAE/g. Statistical analysis using a one-way ANOVA showed a significant influence of drying time on TPC, TFC, and TTC (p < 0,05). The longer the drying time, the higher the antioxidant activity and the content of compounds acting as antioxidants in black garlic powder.

Authors: Andrio David , Saputra Muhammad Ramadhan , Darmayanti Lita
Published: March 2024

Greywater is wastewater from domestic activities sourced from kitchens, bathrooms, and laundry water. Greywater discharged directly into the environment can cause a decrease in surface water quality due to its high organic content, nutrients, pathogenic bacteria, and detergents and surfactants. One method that can be used to remove organic and nutrient content is adsorption. The success of the adsorption process is determined by several factors, such as adsorbent type, dosage, contact time, and others. One adsorbent that has attracted the attention of many researchers in recent years is magnetic biochar. This study aims to remove chemical oxygen demand (COD), total suspended solids (TSS), oil, and grease from greywater with a magnetic biochar adsorbent made from palm shells. The study was conducted by varying the dose of 1.2–8.55 g/l and the contact time of 30–150 minutes. The results showed that increasing the dose and contact time can increase the removal efficiency of COD, TSS, oil, and grease. The best results were obtained at a dose of 8.55 g/l and a contact time of 150 minutes. The removal of COD, TSS, oil, and grease was 87.91%, 88.46%, and 99.96%, respectively.

The research was carried out with the aim of finding out the use of mangrove ecotourism as a learning resource, because almost all regions in Indonesia manage mangrove ecosystem areas into ecotourism. The data collection technique uses proportional random sampling, with descriptive quantitative research methods. The research subjects used in this research process were the population of junior high school students and junior high school science teachers, with a sample of 118 students and 22 science teachers. The instrument used in this research is a questionnaire. The results obtained from the science teacher questionnaire stated that 80.8% of teachers had never integrated mangroves in the science learning process, reinforced by the results of the student questionnaire which stated that 83.2% of teachers had never presented mangrove material in the classroom. In this way, science teachers should change the way they deliver material using the Argument Driven Inquiry (ADI) learning model to make it easier for science teachers to utilize mangrove ecotourism as a learning resource through the stages of the learning model syntax.

Pendidikan karakter merupakan upaya pembentukan peserta didik agar mempunyai karakter yang baik dan diwujudkan dalam perilaku keseharian. Salah satu karakter ideal yang dimiliki orang Indonesia dan patut diteladani adalah mandiri. Mandiri di sini berarti sikap dan perilaku yang tidak mudah tergantung pada orang lain dalam menyelesaikan tugas-tugas. Kurangnya kemandirian pada diri seseorang akan mengakibatkan orang tersebut memiliki kecenderungan untuk bergantung pada orang lain, kurangnya kreativitas, malas, kurang percaya diri dan tidak dapat memecahkan masalahnya sendiri. Dalam konteks proses belajar, terlihat adanya fenomena peserta didik yang kurang mandiri dalam belajar dan memiliki kebiasaan yang kurang baik dalam belajar, seperti: tidak betah belajar lama, belajar hanya menjelang ujian, membolos, menyontek dan mencari bocoran soal-soal ujian. Hal ini dapat menimbulkan gangguan mental setelah memasuki pendidikan lanjutan. Maka setiap lembaga pendidikan hendaknya memperhatikan hal ini dan menyiapkan pembinaan yang tepat agar peserta didik memiliki kemandirian yang baik. Salah satu proses belajar menuju kemandirian adalah dengan membantu melalui self-reparenting siswa. Self-repareting adalah suatu proses pengasuhan ulang diri sendiri. Melalui Self-reparenting seseorang membuat pilihan terhadap kehidupan untuk mengutamakan positif dan mengabaikan yang negatif, sehingga memiliki perasaan OK dan adanya perubahan dalam diri siswa tersebut. Berdasarkan hasi uji hipotesis, bahwa ada peningkatan karakter kemandirian belajar siswa. Hal tersebut dapat dilihat pada tabel 4.5, bahwa dapat diketahui nilai df adalah 35 dan nilai signifikan 0.000 < 0,05 artinya signifikan atau diterima. Kemudian pada tabel 4.7. bahwa diketahui nilai df adalah 29 dan nilai signifikan 0.000 < 0,05 artinya signifikan atau diterima. Ini menunjukkan bahwa layanan klasikal dengan teknik self-reparenting dapat meningkatkan karakter kemandirian belajar siswa di SMA dan SMP negeri Tarakan.

Diseases caused by pathogenic bacteria such as Aeromonas hydrophila are a major health concern. However, the use of red betel leaves (P. crocatum) can serve as a potential solution to this problem due to their antibacterial properties. This research aimed to study the antibacterial activity of red betel leaf extract (P. crocatum), the structure and character of the bacteria inhibited by the extract, and the bioactive components present in the leaves. The results of the disc test showed that the average zone of inhibition was 14.28 mm, while the MIC test results revealed that a dose of 100 mg/L could inhibit bacterial growth (bacteriostatic). Moreover, the crude extract of red betel leaf (P. crocatum) damaged the cell walls and cell membranes of A. hydrophila bacteria, thereby affecting their character and structure. The UV-VIS analysis of red betel leaf extract (P. crocatum) and FTIR analysis with 96% ethanol absorption indicated the presence of flavonoids, saponins, tannins, and alkaloids. These findings suggest that red betel leaves can be used as a natural remedy to fight bacterial infections caused by pathogenic bacteria such as Aeromonas hydrophila
