Abstract

Log ratio is one of the change detection techniques often used in SAR image-based flood inundation analysis where the differences in characteristics between its polarizations are expected to complement each other and provide optimal predictions. This research aimed to identify the characteristics of the output generated from various potential combinations utilizing log ratio change detection. The study utilized Sentinel-1 GRD IW dual polarization mode before and during the flood event  as its main datasource. Briefly, the data processing consists of preprocessing, collocation, and change detection, which were subsequently followed by analysis and evaluation. The analysis results indicated a highly significant difference in characteristics among the four outputs of log ratio change, where the combinations of VH1/VH2 and VV1/VV2 detected much smaller changes compared to the combinations of VV1/VH2 and VH1/VV2. The VV1/VH2 combination acts as a counterpoint to the VH1/VV2 combination, as the changes identified in VV1/VH2 showed a tendency towards positive values, whereas the opposite is true for VH1/VV2. The evaluation results show that the highest frequency of errors in detecting changes sequentially was observed in the combinations of VH1/VV2, VV1/VH2, VV1/VV2, and VH1/VH2.

Abstract

p-methoxycinnamic acid (pMCA) has activity as an anti- inflammatory and analgesic but is difficult to dissolve in water with a solubility of only 0.712 mg/mL at 25 oC. Poor solubility will result a low dissolution rate so that drug absorption becomes limited, affects the bioavailability, and causes therapeutic effect to become less optimal. The formation of co-crystals are able to improve the solubility properties and dissolution rate by physically modifying the active compound. Cocrystals are crystalline materials composed of two or more molecules at specific stoichiometric ratios to form non-covalent bonds. Both saccharin and nicotinamide can be use as coformers because saccharin and nicotinamide were able to increase the solubility and dissolution rate of active compounds due to the formation of non-covalent bonds. The results showed that the formation of cocrystals using the microwave radiation had a higher solubility and dissolution rate of pMCA compared to pure pMCA. The pMCA-nicotinamide cocrystal increased solubility 1.29 times higher than a single pMCA while the pMCA-saccharin cocrystal increased solubility only 1.26 times higher than a single pMCA. In the dissolution rate test, the pMCA-Nicotinamide cocrystal increased the dissolution rate 3.67 times higher while the pMCA-Saccharin only increased 3.55 times higher than a single pMCA. These results show that both cocrystals have better solubility and dissolution rate properties than pure pMCA so it can be said that forming cocrystals can increase the solubility and dissolution rate of pMCA. Based on this study findings, it can also confirm that formation cocrystal pMCA using nicotinamide coformers has agood solubility and dissolution rate than formation cocrystal using saccharin coformers.

Abstract

A series of N2-acyl salicylic hydrazides (S2-S6) and N-(substituted benzylidene) salicylic hydrazides (S7-S9) were synthesized from 2-hydroxybenzohydrazide (S1), using both microwave irradiation and conventional methods, and tested for its in vitro anticancer activity against human lung cancer cell, A549. The salicylic hydrazides were successfully synthesized in good yields (79–98%) and the in-vitro study results indicated that 3,4-dichloro-N'-(2-hydroxybenzoyl)benzohydrazide (S5) was most active among the tested compounds (IC50 value of 68.75 µM). In this work, we applied an integrated approach combining network pharmacology and computational analysis to explore how salicylic hydrazide derivatives affect tyrosine kinase–related pathways. The in-silico findings were in agreement with the in vitro results, indicating that compound S5 produced a docking score of –6.53468 kcal/mol. The findings of this research are expected to support further development toward identifying promising anticancer drug candidates derived from salicylic hydrazide derivatives.

Abstract

Technical Assistance Using Liquid Organic Fertilizer for Improving Small-Scale Rubber Production in Payaraman Barat, Kabupaten Ogan Ilir. Liquid organic fertilizer (POC) is getting more attention from users (researchers, farmers, planters and others) because of the various advantages it has. Its manufacture is not too difficult and can use local raw materials ( agricultural waste, market waste or potential household organic waste). One of the advantages is that it can reduce the cost of fertilization. POC can be used to improve soil fertility and it is hoped that in the end it will be able to increase the productivity of rubber plants. This community service activity aims to provide technical guidance on how to make POC in a simple way and then apply it to rubber plants, accompanied by sanitation of the garden environment by cleaning weeds. There are four waste materials or plant materials used to make POC, namely pineapple peel waste, papaya fruit, banana peel and water hyacinth. The material is fermented in a simple reactor made of a gallon or bucket of used paint that is perforated and fitted with a faucet. The fermentation process is assisted by black soldier flies which will come into the reactor by themselves. After two weeks it will begin to produce fermented liquid. After four weeks the liquid is dried in the sun until it turns dark brown and is ready to use. In this activity, doses of 10, 20, 30 or 40 mL of POC were dissolved into 1 liter. The results of the socialization showed that 15 members of the farmer group did not know about POC and were very interested in using it. Preliminary data (n=30) showed a fairly large variation in sap production (59.7±48.6 grams/tree). Some rubber stems do not release sap, and the highest can reach 142.9 grams/tree with an average of 41 to 83 grams/tree. The collection of results is carried out every week according to latex sales. After 4 weeks of application of POC pineapple peel production can reach 165 to 470 grams/tree.

Abstract

Mathematical and language literacy are fundamental competencies that support students' learning across various disciplines. One effective approach to enhancing mathematical literacy is the use of mathematical coding through spreadsheet software such as Microsoft Excel. This community engagement program aimed to improve the mathematical literacy and Excel-based coding skills of students at Junior High School 5 North Indralaya, Ogan Ilir Regency, Indonesia. The program was implemented through training and mentoring sessions conducted in the school's computer laboratory, involving 32 students who shared 16 computers. Students learned to apply Excel formulas and functions to solve mathematical problems. The training consisted of three sessions, each lasting two instructional hours, covering basic arithmetic, plane and solid geometry, and introductory statistics. Although the participants had not formally studied statistics, they successfully used Excel formulas to calculate the mean, median, mode, maximum, and minimum values. Program effectiveness was evaluated using pre-test and post-test assessments. The results demonstrated significant improvements in both mathematical literacy and Excel-based coding skills. All students showed better mathematical performance, as indicated by the increased number of correct answers across all mathematical problems. Coding proficiency also improved substantially; while only two students correctly answered the Excel coding questions in the pre-test, all participants answered them correctly in the post-test. These findings indicate that Excel-based mathematical coding is an effective instructional approach for strengthening mathematical literacy, computational thinking, and digital skills among junior high school students.

Abstract

Turmeric is a herbal remedy with a million benefits that has been used by Indonesians for centuries. Tenaru Village, one of the villages, produces a lot of turmeric annually in Gresik Regency. However, this turmeric is sold only as a cash crop or a simple product at a low price. This program aims to provide training for Tenaru village farmers to create innovative turmeric-based products to increase their selling value. Furthermore, this program aims to increase participants' understanding of safe food packaging as part of safe, high-quality food products. The program's success was evaluated quantitatively, showing a statistically significant increase in pre- and post-test scores. The qualitative assessment using Bloom's taxonomy analysis showed an increase in participants' abilities, from not knowing to being able to teach other people in that village. This indicates that the program has had a significant impact on participants' ability to develop innovative turmeric-based instant beverage products.
