Selenization process in simple spray-coated CIGS film

The synthesis process to produce a decent thin-film CIGS layer with simple, easy, and low-cost are essential factors in CIGS solar cell technology. This study synthesized a thin layer of CIGS by a simple spray coating method and selenization process. The temperature substrate and distance between the nozzle and target are controlled to provide an even thickness coating. A one-stage selenization was carried out with temperature variations of 350, 400, and 500 °C and a three-stage selenization process as the comparison was made at 400 and 520 °C. The surface morphology, thickness, and optical properties of CIGS films were investigated as a function of the temperature of selenization. The complete CIGS solar cell prototype consists of a window, buffer, and CIGS absorber layer. The buffer layer used is ZnS deposited by the chemical bath deposition method, while the window layer of ZnO is deposited by the spin coating method. The SEM characterization showed a thinner layer of CIGS as temperature, and the heating rate of the selenization increased. The increasing selenization temperature also affects the Selenium deficiency that causes low Ga/(In + Ga) content and increases the bandgap energy. By the grain growth model and the kinetic study yielded estimated activation energy, which one step selenization of the process is higher than the three steps of the selenization process. PV82QJC8Y

PEMBERDAYAAN KELOMPOK TANI MELALUI TEKNOLOGI FERMENTASI PENGOLAHAN ECENG GONDOK UNTUK PAKAN UNGGAS DI DESA TERSIDILOR KECAMATAN PITURUH KABUPATEN PURWOREJO

ABSTRAKMakalah ini menyampaikan uraian tentang proses  penumbuhan pengetahuan dan ketrampilan tentang pengolahan eceng gondok  yang difermentasi untuk pakan unggaskepada Kelompok  tani  Maju Bersama yang merupakan satu satunya kelompok tani yang mengelola tanaman pangan dan unggas (ayam dan bebek) di TersidiLor  Kecamatan Pituruh Kabupaten Purworejo. Tujuan pengabdian ini adalah pemberdayaan kelompok tani  dengan memberi pemahaman dan keterampilan kepada masyarakat melalui penyuluhan dan pelatihan, agar memiliki kemampuan untuk mengembangkan potensi yang dimiliki dalam bidang pertanian dan peternakan. Rangkaian kegiatan yang dilakukan sejak Kuliah Kerja Nyata Tematik Universitas Muhammadiyah Purworejo di laksanakan selama 1 bulan yang  terdiri dari (1) orientasi lokasi, (2) persiapan dan perencanaan penyuluhan dan pelatihan , (3) kegiatan pelatihan, (4) pengamatan hasil pelatihan, dan (5) evaluasi terhadap pelatihan. Pengumpulan data dari kajian ini dilakukan dengan metode observasi dan wawancara  terhadap  mitra yaitu anggota  kelompok tani maju bersama berjumlah 15 orang yang menjadi peserta kegiatan. Berdasarkan dari hasil evaluasi dan pembahasan, maka dapat disimpulkan bahwa anggota kelompok tani maju bersama di  desa tersidiLor diKecamatan Pituruh kabupaten Purworejo antusias dan menyadari bahwa eceng gondok dapat dimanfaatkan apabila diberi sentuhan teknologi fermentasi  khususnya untuk pakan ternak unggas seperti ayam dan bebek. Salah satu bagian penting dari kegiatan ini adalah peserta mengetahui bahwa eceng gondok dengan tambahan konsentrat, EM4/tetes tebu yang difermentasi dengan takaran sesuai dapat  menambah  pengetahuan dan ketrampilan dari bidang pertanian dan peternakan.Disisi lain diharapkan bahwa dengan tambahan pakan eceng gondok yang difermentasi menjadi cadangan pakan unggas dan dapat menambah penampilan dan produksi telur pada unggas . Kata kunci : eceng gondok; fermentasi; pakan ungags; kelompok tani. ABSTRACTThis paper provides a description of the process of growing knowledge and skills to the Maju Bersama farmer group, which is the only farmer group that manages food crops and poultry (duck and chicken) in Tersidi Lor, Pituruh District, Purworejo Regency regarding the processing of fermented water hyacinth for poultry feed. The purpose of this service is to empower farmer groups by providing understanding and skills to the community through counseling and training, so that they have the ability to develop their potential in agriculture and animal husbandry. The series of activities carried out since the Purworejo Muhammadiyah University Thematic Real Work Lectures were carried out for 1 month consisting of (1) location orientation, (2) counseling and training preparation and planning, (3) training activities, (4) observation of training results, and (5) evaluation of training. Data collection from this study was carried out using observation and interview methods with partners, namely members of the Advanced Farmer Group, totaling 15 people who were participants in the activity. Based on the results of the evaluation and discussion, it can be concluded that the members of the farmer group in the tertiary village of Lor in the Pituruh District, Purworejo Regency, are enthusiastic and realize that water hyacinth can be used if given a touch of fermentation technology, especially for poultry feed such as chickens and ducks. An important part of this activity is that the participants know that water hyacinth with additional concentrate, fermented EM4/sugar molasses at appropriate doses can increase their knowledge and skills in agriculture and animal husbandry. poultry feed and can increase the appearance and egg production in poultry. Keywords : water hyacinth; fermentation; poultry feed; farmer group

Analisis Kinerja Keuangan Perbankan Syariah Di Indonesia Sebelum Dan Selama Masa Pandemi Covid-19

Tujuan dari penelitian ini untuk menganalisa kinerja keuangan perbankan syariah di Indonesia baik sebelum maupun selama masa pandemi covid-19 yang diukur dengan menggunakan rasio CAR, ROA, NPF, BPO, NOM dan FDR. Analisis data yang digunakan termasuk dalam jenis kuantitatif. Sumber data yang digunakan berupa statistik perbankan syariah bulanan tahun 2017-2022. Populasi dalam penelitian ini adalah seluruh bank syariah di Indonesia yang terdaftar pada Otoritas Jasa Keuangan (OJK) pada periode 2017-2022. Metode analisis yang digunakan yaitu statistic deskriptif dan uji beda paired sample t-test. Hasil penelitian menggunakan uji beda paired sample t-test menunjukkan adanya perbedaan yang signifikan pada rasio CAR, ROA, NPF, BOPO, NOM dan FDR sebelum maupun selama masa pandemic covid-19 di Indonesia

Proceedings of the 3rd International Conference on Community Engagement and Education for Sustainable Development

This proceeding contains articles on the various ideas of the academic community presented at The 3rd International Conference on Community Engagement and Education for Sustainable Development (ICCEESD 2022) organized by the Universitas Gadjah Mada, Indonesia on 7th-8th December 2022.  ICCEESD is a biannual forum for sharing, benchmarking, and discussing HEI’s activities in developing Education for Sustainable Development towards community engagement. Education for Sustainability as a teaching strategy for resolving community challenges through formal, informal, or non-formal education is expected to benefit from various community service best practices by academics, researchers, and students. The 3rd ICCEESD has “Strengthening Education for Sustainability Towards Better Community Engagement” as its theme this year. It is expected that the 3rd ICCEESD will provide a forum for the presenters and participants to exchange best practices, policies, and conceptual implementation of Education for Sustainability towards better community engagement and explore ideas to address community needs.  Conference Title: 3rd International Conference on Community Engagement and Education for Sustainable DevelopmentConference Theme: Strengthening Education for Sustainability Towards Better Community EngagementConference Acronyms: ICCEESD 2022Conference Date: 7th-8th December 2022Conference Location: Grand Rohan Jogja Yogyakarta, IndonesiaConference Organizer: Universitas Gadjah Mada, Indonesi
