Abstract

This research aims to develop and evaluate a stakeholder engagement model in development planning in Bina Baru village, Sidenreng Rappang Regency through the ‘Ladda-Ladda’ approach. The model aims to improve community participation and coordination between the government and the community in the village development planning process. Qualitative research methods were used, with participant observation and in-depth interviews as the main data collection techniques. Data analysis was conducted through thematic coding to identify patterns and emerging themes related to stakeholder engagement. The research findings show that the implementation of the ‘Ladda-Ladda’ model has succeeded in increasing the active participation of the community, which is reflected in their increased involvement in expressing their aspirations and participating in village deliberations. This strengthens social relations and trust between the community and the government, resulting in a more relevant and inclusive development plan. Theoretically, this study contributes to the literature on village development by integrating the concepts of community participation and coordination theory into a model that can be applied in different villages. However, this study has limitations in generalizing the results because the study was conducted in only one village. In addition, the implementation of this model requires significant time and resources, especially in building community participation capacity. Further research is needed to test the effectiveness of this model in a broader context and to develop more efficient strategies for its implementation.

Abstract

Geothermal silica waste offers convenient, economical, and environmentally friendly material with high hydrophobicity to produce thin films. Silica-thin films from geothermal waste using the sol-gel method, though, no addition of AgNO3 was conducted for antibacterial functions. This study aims to produce silica-thin films from geothermal waste with the addition of AgNO3 and analyze the antibacterial activity. The procedures carried out in this research were (i) an acid leaching process using HNO3; (ii) the production of silica thin film with and without the addition of AgNO3; (iii) thin film characterization including a water contact angle measurement (WCA), XRF, FTIR, XRD and SEM-EDX on silica thin film samples with and without the addition of AgNO3; and (iv) antibacterial activity test. The results show the optimum HNO3 concentration for the acid leaching process was 20%, yielding 99.08% SiO2 by mass. The WCA of the silica thin film in the presence and absence of AgNO3 reached a value of ±160°, indicating the addition of AgNO3 did not decrease the contact angle of the silica thin film. This research employed smart deconvolution of IR Spectra using Fityk software which reveals a higher area ratio for Si-O-Si relative to Si-OH. Furthermore, it was observed that the silica thin films exhibited an amorphous morphology, both without and with the addition of AgNO3, with Ag discovered to be dispersed on the thin film. However, despite the presence of Ag, both TF20 and TF20+Ag samples were found to be ineffective in inhibiting bacterial growth, as evidenced by bacteria-free zones on the samples.

Abstract

MDMA (3,4-Methilendioxymethamphetamine) atau sering dikenal ekstasi yaitu senyawa turunan amfetamin yang dapat menyebabkan rasa senang berlebihan dan biasanya banyak digunakan pada festival musik dansa atau diskotik. Penggunaan MDMA dapat memepengaruhi resiko kesehatan yang serius diantaranya dalam jangka pendek menyebabkan hipertermia, kejang, aritmia, hiponatremia, rhabdomiolisis dan kerusakan jangka panjang pada sistem saraf pusat. Salah satu metode untuk mengidentifikasi adanya senyawa MDMA yaitu menggunakan tes warna dan GCMS “Gas Chromatography-Mass Spectrometry”. Uji tes warna merupakan uji screening untuk mengatahui ada tidaknya senyawa MDMA dalam sampel dengan menggunakan reagen marquis. Sedangkan GCMS yaitu instrumen yang dapat digunakan untuk mengetahui kandungan suatu senyawa dalam sampel dengan membandingkan waktu retensi antara senyawa yang belum diketahui dengan waktu retensi referensi. Pada penelitian ini, penulis melakukan identifikasi barang bukti tablet menggunakan analisis tes warna dan GCMS. Hasil yang diperoleh pada uji tes warna yaitu terjadi perubahan warna dari merah menjadi hitam. Kemudian dilakukan uji konfirmatif menggunakan metode GCMS. Hasil yang diperoleh yaitu pada spektra GC terdapat dua puncak yang menonjol yaitu MDMA dan kafein dengan waktu retensi berturut-turut yaitu 10,875 menit dan 13,341 menit. Hasil ini sesuai dengan Library W10N11. Berdasarkan hasil pengujian tersebut, dapat disimpulkan bahwa sampel barang bukti tablet merah merupakan psikotropika golongan 1 yaitu ekstasi/ MDMA.

Abstract

Nanopowder pigments of CeO2 and CeO2:Fe were synthesized by precipitation method at a moderate calcination temperature of 500oC. The pigments exhibited pale yellow for CeO2 nanopowder and brick red for CeO2:Fe nanopowder. Both pigments possessed mesoporous and cubic fluorite structures of CeO2. The incorporation of Fe into CeO2 reduced crystallite size and increased surface area. Moreover, it widens bandgap energy and significantly improved the absorption property of CeO2 nanopowder.
