Judul: The Effectiveness of the Empowerment Program and Relationship with the Household Empowerment of Farmer Group Members during the COVID-19 Pandemic
Abstrak: Pandemi COVID-19 turut berdampak terhadap pelambatan distribusi hasil pertanian termasuk kopi dan pecapaian tujuan program pemberdayaan. Penelitian ini bertujuan untuk menganalisis efektivitas program pemberdayaan dan hubungannya dengan keberdayaan rumah tangga anggota kelompok tani pada masa pandemi COVID-19. Data primer diperoleh melalui wawancara terstruktur menggunakan kuesioner terhadap 30 petani. Data sekunder diperoleh dari BPS dan lembaga terkait. Data kualitatif dikumpulkan melalui wawancara mendalam dengan informan dan observasi lapang. Uji korelasi rank spearman digunakan untuk menganalisis hubungan antar variabel penelitian. Hasil penelitian menunjukkan bahwa terjadi penurunan pada aktivitas program pemberdayaan pada masa pandemi dan keberdayaan anggota kelompok tani di Kelompok Tani Mekar Wangi Jaya juga semakin berdaya. Semakin efektif program pemberdayaan, maka rumah tangga anggota kelompok tani pada masa pandemi COVID-19 semakin berdaya., The COVID-19 pandemic has hampered the distribution of agricultural products, including coffee beans and influenced the achievement of empowerment program. This study aims to analyze the effectiveness of the empowerment program and its relationship with household empowerment of farmer group members during the COVID-19 pandemic. Primary data were obtained through structured interviews using questionnaires to 30 farmers. Qualitative data were collected through in-depth interviews with informants and field observations. Rank spearman correlation test was used to analyaze correlations between the research variables. The results showed that there was a decline in empowerment program activities during the pandemic and the power of farmer group members at the Mekar Wangi Jaya Farmers Group also decreased. Farmer group empowerment program has positive correlation with power and welfare of the farmer group member.

Judul: Social Capital, Economic Coping Strategy and Family Well-Being of Vegetable Farmer during the Covid-19 Pandemic
Abstrak: Dampak pandemi bagi petani sayuran yaitu menurunnya pendapatan yang mengganggu tingkat kesejahteraan keluarga petani. Tujuan dari penelitian ini adalah menganalisis pengaruh modal sosial dan strategi koping ekonomi terhadap kesejahteraan keluarga petani sayuran. Penelitian ini merupakan penelitian deskriptif dan penarikan contoh dilakukan dengan cara two stage random sampling. Lokasi penelitian ini adalah Desa Paniaran, Kecamatan Siborong-borong, Kabupaten Tapanuli Utara, Provinsi Sumatera Utara. Subjek dalam penelitian ini adalah istri sebanyak 85 orang. Data dikumpulkan melalui wawancara dengan alat bantu kuesioner. Data dianalisis dengan analisis jalur menggunakan aplikasi SPSS 25. Hasil analisis menunjukkan bahwa modal sosial memiliki pengaruh tidak langsung terhadap kesejahteraan subjektif, yaitu melalui strategi koping ekonomi dan melalui kesejahteraan objektif. Strategi koping ekonomi memiliki pengaruh negatif tidak langsung terhadap kesejahteraan subjektif. Pengaruh tidak langsung ini melalui kesejahteraan objektif. Peningkatan kesejahteraan dapat dilakukan dengan cara menurunkan jumlah strategi koping ekonomi dan meningkatkan modal sosial., The impact of the pandemic for vegetable farmers is the decline in income which disrupts the well-being level of the farmer family. The purpose of this study was to analyze the effect of social capital and economic coping strategies on the well-being of vegetable farmer families. This research is a descriptive study and sampling was done by means of two stage random sampling. The location of this research is Paniaran Village, Siborong-borong District, North Tapanuli Regency, North Sumatra Province. The subjects in this study were 85 wives. Data are collected through interviews with a questionnaire tool. The data are analyzed by path analysis using the SPSS 25 application. The results of the analysis show that social capital has an indirect effect on subjective well-being, namely through economic coping strategies and through objective well-being. Economic coping strategies have an indirect negative effect on subjective well-being. This indirect effect is through objective well-being. Well-being improvement can be done by reducing the number of economic coping strategies and increasing social capital.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
