Abstract

Coal mining activities carried out openly can have a negative impact on the environment. One of the environmental damages that occurs is the loss of habitat for soil-level insects. This research was conducted to identify the diversity of soil surface insect species in post-coal mining land of PT. Bukit Asam Tbk Tanjung Enim IUP Banko Barat at various ages of reclamation. Soil surface insect samples were collected using the pitfall trap method which was carried out for 1x24 hours. The results showed that the highest presence of soil surface insect species occurred in aged 6 years with a total of 128 individuals and was dominated by the order Hymenoptera. The species diversity index in post-coal mining land aged 6 years, namely 1.51, is classified as moderate. The lowest presence of soil surface insects occurred in aged 2 years with a total of 24 individuals. The species diversity index in post-coal mining land aged 2 years, namely 0.85, is relatively low. Thus, the research results show that the diversity of surface soil insects is influenced by the age of reclamation. The longer the land is managed, the higher the index of diversity of soil surface insect species in post-coal mining land.

Abstract

Program Gerakan Literasi Sekoalah (GLS) di SDN 1 Sumbersari Kota Malang sudah dilaksanakan. Akan tetapi, selain belum maksimal, belum ada yang mengelola tahapan program dengan baik. Tujuan program pengabdian ini untuk memberikan pendampingan sekolah khususnya pada Tim Literasi Sekolah (TLS) dalam pengelolaan program GLS. Metode pendekatan yang digunakan adalah memberikan sosialisasi, diskusi, workshop, praktik langsung, dan evaluasi. Hasil pendampingan dapat menunjukkan; 1) terbentuknya struktur organisasi TLS, 2) Program literasi yang disusun oleh TLS mampu memberikan informasi dasar keberlangsungan dan keterlaksanaan GLS di tahap pembiasaan, pengembangan, serta pembelajaran. Berdasarkan hasil, dapat disimpulkan bahwa adanya pendampingan TLS program-program leterasi menjadi lebih terstruktur dan terkelola dengan baik.

Abstract

Background: The high ability of community environmental literacy can form ideal environmental conditions, but indigenous peoples and urban communities have different understandings of environmental conditions. This study aimed to determine differences in the environmental literacy of indigenous peoples and urban communities on Lombok Island. Methods: The objects of this research are the indigenous people of Bayan Village, North Lombok, and the people of the Dasan Sari Environment, Mataram City, West Lombok: quantitative research methods, quantitative descriptive approaches, and survey research types. Data collection tools are observation, interviews, and questionnaires. Data analysis using SPSS, data analysis techniques by calculating the mean score of the questionnaire. Results: The study obtained a mean environmental literacy value for the indigenous people of Bayan Village at 214.37 and for the Dasan Sari Environmental community at 240.56. The results of the hypothesis testing in this study obtained a significance value greater than 0.05 and t-count < t-table. Conclusions: There was no real difference in environmental literacy between indigenous peoples and urban communities on Lombok Island.

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

Kekerasan pada komponen mesin yang terbuat dari baja, dapat diperoleh melalui proses perlakuan panas atau perlakuan permukaan. Proses peningkatan kekerasan menggunakan panas kemudian dengan dinginkan dengan media pedingin serta holding time yang ditentukan merupakan cara yang banyak dilakukan untuk baja karbon medium dan tinggi. Penelitian untuk memperoleh hasil kekuatan tarik dengan tujuan untuk mengetahui pengaruh media pendingin dan holding time pada proses perlakuan panas terhadap kekuatan tarik material ST 41. Metode penelitian yang digunakan eksperimen murni (true experimental) dengan analisa data menggunakan analysis of varians pada program minitab 16. Hasil penelitian menunjukkan variasi yang mampu memberikan pengaruh paling besar terhadap kekuatan tarik adalah holding time selama 15 menit dengan media pendingin air sebesar 64 kN. Hasil analisa untuk holding time memiliki pengaruh terhadap kekutan tarik dengan p-value sebesar <0,05 (nilai signifikan) sedangkan untuk media pendinginan tidak memiliki pengaruh terhadap kekuatan tarik dimana p-value sebesar >0,05 (nilai signifikan). Sehingga dapat disimpulkan faktor holding time berpengaruh terhadap kekuatan tarik dan untuk faktor media pendingin tidak berpengaruh terhadap kekuatan tarik secara signifikan.

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.
