The objective of this research is to reduce the interfacial tension of sodium lignosulfonate (SLS). SLS formulation (1%) showed the interfacial tension of 2.34 mN/m. This value is still relatively large when compared to interfacial tention of required surfactant for enhanced oil recovery (EOR). The terms of surfactants that can be used in EOR must have ≤10-3 mN/m interfacial tension. The performance of SLS was expected to be improved by adding the epoxide compound and co-surfactants (1-octanol). Epoxide compound was made by reacting kapok oil with acetic acid and hydrogen peroxide with in-situ method. Temperature of epoxidation reaction was varied i.e. 60°C, 70°C and 80°C, while the time of reaction was varied from 15 to 90 minutes. The evaluation showed that equation of the reaction rate coefficient (k) for the epoxide was ????= 124,82 exp (−24,14/RT). The addition of the epoxide compound 0.5% w/w of the formulation SLS was able to reduce the interfacial tension value up to 9.95 x 10-2 mN/m. The addition of co-surfactant (1-oktanol) was varied between 0.1 and 0.4% of the total mass (SLS + epoxide + water formation). The lowest interfacial tension (2.43 x 10-3 mN/m) was obtained by co-surfactants addition of 0.2% w/w. Keywords: Sodium lignosulfonat, epoxidation kapok oil, co-surfactant, interfacial tension, enhanced oil recovery Penelitian ini bertujuan untuk menurunkan tegangan antarmuka dari sodium lignosulfonat (SLS). Pengukuran tegangan antarmuka yang telah dilakukaan pada formulasi sodium lignosulfonat atau SLS (1%) memiliki nilai tegangan antarmuka sebesar 2,34 mN/m. Nilai tegangan antarmuka dari SLS ini masih relatif besar jika dibandingkan dengan syarat surfaktan untuk perolehan kembali minyak bumi atau enhanced oil recovery (EOR). Syarat surfaktan sebagai agen EOR adalah memiliki nilai tegangan antarmuka sebesar ≤10-3 mN/m. Kekurangan dari SLS diharapkan dapat diperbaiki dengan penambahan senyawa epoksida dan kosurfaktan (1-oktanol). Senyawa epoksida dibuat dengan mereaksikan sabun minyak biji kapuk dengan asam asetat dan hidrogen peroksida secara insitu. Reaksi epoksidasi divariasikan pada suhu 60oC, 70oC, dan 80oC, sedangkan waktu reaksi divariasikan pada rentang 15 dan 90 menit. Persamaan konstanta laju reaksi untuk epoksidasi diperoleh sebesar ????= 124,82 exp (−24,14/RT). Penambahan senyawa epoksida 0,5% w/w pada formulasi SLS mampu menurunkan nilai Tegangan antarmuka hingga 9,95x10-2 mN/m. Penambahan kosurfaktan 1-oktanol divariasikan antara 0,1–0,4% dari massa total formulasi utama (SLS+Epoksida+Air Formasi). Nilai tegangan antarmuka terkecil diperoleh pada penambahan kosurfaktan sebanyak 0,2% w/w, yaitu sebesar 2,43x10-3 mN/m.

The phenomena of surface plasmon resonance (SPR) has been observed. SPR is reflectance curve as a function of incident angle in Kretschmann configuration. Surface plasmon is electromagnetic waves propagation in the interface area between metal and dielectric that can be excited by using attenuated total reflection (ATR) method. The result of experiment explains that the SPR angle on the thin film system of the prism/silver 1 and the prism/silver 2 is (42.8± 0,05)º with the reflectance value 0.32 and 0.44 respectively. On the prism/silver/silver nanoparticle system, it is obtained that SPR angle value is (4,29 ± 0,05) with the reflectance value 0.29 for the silver 1 and 0.31 for the silver 2. After the thin film system is added with 40% of formalin, SPR angle becomes (43,0 ± 0,05)º with the reflectance value 0.44. Then, after the thin film system is added with 100% of formalin, SPR angle becomes (43,2 ± 0,05)ºwith the reflectance value 0.4. The shifting SPR angle shows that SPR have capability as formalin sensor.

Predicting crypto prices is a challenge because the crypto market is very volatile and unpredictable. In this work, we present a crypto price prediction system that uses the regression method to plot curves on a historical crypto price dataset. The system consists of several stages, including data collection, data pre-processing, model training, prediction, and evaluation. Model performance is evaluated by comparing the predictions made by the model with actual prices and calculating metrics such as mean absolute error or mean squared error. The system is expected to help in deciding to buy, sell or hold owned crypto assets and the system used uses the Python programming language which is one of the languages which has machine learning features for the implementation of artificial intelligence (AI).

This study aims to analyze the digital transformation of educational administration at MTs Miftahul Jannah, Ngawi, in order to improve service quality and operational efficiency. In the digital era, educational institutions are required to shift from manual administrative processes to integrated digital systems to ensure transparency and data-driven decision-making. This research employed a qualitative approach using a field research design. Data were collected through in-depth interviews, focus group discussions (FGDs), and field observations involving the principal, administrative staff, and students. Data analysis followed the interactive model of Miles and Huberman, consisting of data reduction, data display, and conclusion drawing. The findings indicate that MTs Miftahul Jannah has successfully initiated digital transformation in financial administration by utilizing digital platforms such as Google Forms and AppSheet, which contributed to improved efficiency, accuracy, and responsiveness of administrative services. However, the transformation has not yet been fully integrated due to challenges related to unstable internet connectivity and limited digital literacy among human resources. The study implies that sustainable digital transformation in madrasah administration requires continuous capacity building, systematic training programs, and strengthened technological infrastructure. These efforts are essential to achieving a fully integrated digital education service system by 2029
