Study of Zno:Ga Thin Film Structure With Variation of Plasma Power Using the DC Magnetron Sputtering Method Putut Marwoto; Budi Astuti; Sugianto Sugianto
Journal of Natural Sciences and Mathematics Research Vol 4, No 2 (2018): December
Publisher : Faculty of Science and Technology, Universitas Islam Negeri Walisongo Semarang

ZnO:Ga thin films grown on a corning glass substrate by the DC Magnetron Sputtering method have been successfully grown. The purpose of this study was to study the effect of plasma power on the resulting thin film structure. The quality and structure of the films were studied using X-ray duffraction (XRD), and scanning electron microscopy (SEM). Based on XRD characterization, it was found that the ZnO:Ga thin film has a hexagonal wurtize structure on the C-axis with orientation planes (002) and (101). The quality of the resulting thin films can also be seen from the value of full-width at half maximum (FWHM) in the orientation plane (002) which increases with increasing plasma power during the growth process from 0.13°- 0.16°. The larger the FWHM value, the smaller the crystal grain size so that the structure becomes less good. This is supported by the surface morphology of the film which is less dense when the plasma power increases. ©2018 JNSMR UIN Walisongo. All rights reserved.

This work investigated the effect of post-annealing treatment on the fabrication of zinc oxide (ZnO) thin film by spraying deposition method. Based on SEM analysis, the annealed ZnO thin film at 400˚C presented better uniformity as compared to the non-annealed film. Further measurement by UV-Vis revealed that the lowest optical band gap energy (Eg) (3.22 eV) was achieved by 400˚C sample. These results confirmed that post-annealing treatment enhanced the optical and morphological properties of the fabricated ZnO thin film.

The reduced graphene oxide (rGO) and metal (Cu,Zn)-oxide composites were prepared using a one-step hydrothermal technique. The role of (Cu,Zn)-oxide on the physical and electrochemical properties of the composite was investigated. The composite consists of various shapes of ZnO nanoflowers and micro-spheres, as well as Cu-oxide nanoflakes and octahedron-like shapes. The (Cu,Zn)-oxides were formed in between the rGO layers and observed in the rGO-ZnO, rGO-CuO, and rGO-CuO-ZnO composites. The presence of ZnO, CuO, and rGO within the composite structure is also confirmed by the analyses of crystal structure, microstructure, and surface functional groups. Some excess impurities remaining from the surfactant give considerable differences in the electrochemical performance of the composites. The specific capacitance values of the rGO, rGO-ZnO, rGO-CuO, rGO-(0.5CuO-0.5ZnO), and rGO-(0.25CuO-0.75ZnO) composites are 9.32, 58.53, 54.14, 25.21, and 69.27 F/g, respectively. The formation ofa double metal-oxide structure as well as their insertion into the rGO sheet can significantly improve the electrochemical properties of the supercapacitor.

Isu pangan merupakan persoalan krusial bagi seluruh lapisan masyarakat termasuk masyarakat perkotaan. Pemenuhan kebutuhan pangan dapat dilakukan dengan bertanam atau berternak. Urban farming atau pertanian perkotaan merupakan salah satu kunci pemberdayaan untuk ketahanan pangan berkelanjutan. Budidaya akuaponik merupakan sistem terintegrasi antara akuakultur dan hidroponik, limbah budidaya ikan berupa sisa metabolisme dan sisa pakan dimanfatakan untuk pupuk tanaman. Akuaponik dapat dilakukan dalam skala besar ataupun kecil. Keterbatasan lahan di Kelurahan Kalisegoro Kecamatan Gunungpati, Kota Semarang menyulitkan masyarakat melakukan kegiatan bercocok tanam secara konvensional. Tujuan dari kegiatan pengabdian ini adalah untuk memberdayakan warga Kalisegoro dalam memahami konsep urban farming, khususnya akuaponik, dan terampil menerapkan teknologi akuaponik. Metode yang digunakan adalah (1) participatory urban appraisal, (2) participatory technology development, yaitu workshop pemanfaatan teknologi tepat guna berintegrasi ilmu pengetahuan dan kearifan lokal yaitu akuaponik, (3) pendekatan sosialisasi melalui pendampingan dalam membuat dan merawat akuaponik sampai berhasil. Hasil pengabdian menunjukkan peningkatan pemahaman peserta pengabdian terkait konsep hidroponik dan akuaponik, terampil menyemai bibit tanaman hidroponik, terampil mendesain instalasi akuaponik, terampil menghitung nutrisi yang diperlukan dan terampil merawat akuaponik.

The essential 21st-century skills, including collaboration, communication, creativity, and critical thinking, are valuable when combined with computational thinking (CT) skills. Teachers at Sekolah Indonesia Kuala Lumpur (SIKL) need to be capable of implementing CT in their teaching. Since CT is relatively new to the learning environment at SIKL, the implementation of CT in science education needs to be strengthened, particularly for science teachers at SIKL. The issue to be addressed is empowering teachers to implement CT in science teaching at SIKL. The partner’s problem-solving method is based on a facilitation-based Action Learning model. This facilitation-based action learning is divided into three stages: preparation, implementation, and evaluation. The activities include programmed workshops and discussions to understand CT, its importance as a fundamental skill across subjects in today’s and future digital era, and the need for SIKL teachers to acquire foundational CT skills. In addition to workshops and discussions, support was provided in the form of workshops for practicing CT integration and evaluating it within science education. This activity involved 30 SIKL teachers from various levels and subject areas. Before the training, only 45% of participants understood CT concepts, and only a few had applied CT, but afterward, 80% of teachers were able to integrate CT into their teaching. Intensive support in planning, implementing, and evaluating CT-based learning had a significant positive impact. Despite challenges due to the participants' diverse educational backgrounds, the facilitation-based Action Learning method proved effective in addressing these differences and enhancing active participation. This initiative is expected to serve as a starting point for broader CT implementation within SIKL.

Sumurrejo, Gunungpati, is one of the fostered villages of the Mathematics and Natural Sciences Faculty, Universitas Negeri Semarang, which is located about 8 kilometers from the Unnes Sekaran Campus. This village has several potentials, including UMKM for making tempeh which have been fostered by FMIPA for the last three years. This village is geographically quite strategic because it is traversed by inter-district roads which are quite busy. Seeing the potential and current technological changes, UMKM in Sumurrejo can continue to be developed through digital media. One of the solutions offered by the FMIPA Unnes community service team is through digital marketing socialization and training on the creation and management of online stores. In this activity, socialization was carried out to all UMKM owners in Sumurrejo, as well as training on the creation of an online store for youth organizations in Sumurrejo. The online shop managed by youth organizations is expected to be able to become a job for local youth and help marketing UMKM products in Sumurrejo.
