Judul: Factors Affecting Rice Availability in West Java Province
Abstrak: Ketahanan pangan merupakan salah satu hal penting yang menjadi urgensi sebuah negara. Ketahanan pangan terdiri dari tiga pilar, yaitu ketersediaan pangan (food availability), keterjangkauan pangan (food accessibility), dan pemanfaatan pangan (food utilization). Salah satu pangan yang menjadi kebutuhan pokok masyarakat Indonesia adalah beras sehingga ketersediaan beras menjadi hal yang sangat penting. Provinsi Jawa Barat sebagai salah satu lumbung padi di Indonesia berperan penting dalam menopang ketersediaan beras nasional. Adapun produksi padi di Provinsi Jawa Barat mengalami fluktuasi dalam kurun waktu lima tahun terakhir dimana produksi padi di 19 wilayah kabupatennya jauh lebih besar dibandingkan dengan di delapan wilayah perkotaannya. Selain itu, luas areal panen padi dan jumlah konsumsi beras per kapita di Provinsi Jawa Barat juga mengalami fluktuasi. Tujuan dari penelitian ini, yaitu mengkaji perkembangan luas areal panen padi, jumlah penduduk, curah hujan, produktivitas lahan, jumlah konsumsi beras per kapita, dan produksi padi 27 kabupaten/kota di Provinsi Jawa Barat dengan statistik deskriptif menggunakan tools Stata 17 dan Microsoft Excel 2021, menghitung rasio ketersediaan beras 27 kabupaten/kota di Provinsi Jawa Barat dengan menggunakan indikator rasio ketersediaan beras berdasarkan Food Security and Vulnerability Atlas (FSVA), serta menganalisis faktor-faktor yang mempengaruhi ketersediaan beras di Provinsi Jawa Barat menggunakan metode analisis regresi data panel dinamis Generalized Method of Moments (GMM) dengan tools Stata 17. Adapun data penelitian ini adalah data sekunder 27 Kabupaten/Kota di Provinsi Jawa Barat periode tahun 2013 sampai dengan 2022 bersumber dari Badan Pusat Statistik (BPS) serta Dinas Ketahanan Pangan dan Peternakan Provinsi Jawa Barat. Hasil dari penelitian ini adalah berdasarkan range indikator rasio ketersediaan beras ketahanan pangan Provinsi Jawa Barat tahun 2013 sampai dengan 2017 mengalami surplus sedang, kecuali pada tahun 2015 mengalami surplus rendah, serta tahun 2018 sampai dengan 2022 mengalami surplus rendah, kecuali tahun 2020 mengalami defisit rendah. Adapun faktor-faktor yang mempengaruhi ketersediaan beras di Provinsi Jawa Barat, yaitu luas areal panen padi, jumlah penduduk, curah hujan, produktivitas lahan serta produksi padi., Food security is one of the important things that become the urgency of a country. Food security consists of three pillars, namely food availability, food accessibility, and food utilization. One of the staple foods for the Indonesian people is rice, so the availability of rice is very important. West Java Province as one of the rice barns in Indonesia plays an important role in sustaining national rice availability. The production of rice in West Java Province has fluctuated in the last five years where rice production in its 19 districts is much greater than in its eight urban areas. In addition, the rice harvest area and the amount of rice consumption per capita in West Java Province have also fluctuated. The objectives of this study are to examine the development of rice harvest area, population, rainfall, land productivity, total rice consumption per capita, and rice production in 27 districts/cities in West Java Province using descriptive statistics using Stata 17 and Microsoft Excel 2021 tools, to calculate the rice availability ratio of 27 districts/cities in West Java Province using rice availability ratio indicators based on the Food Security and Vulnerability Atlas (FSVA), and to analyze the factors affecting rice

Judul: Determinants of Food Security in The Rice-Producing Province in Indonesia for The 2019-2023 Period
Abstrak: Ketersediaan pangan yang melimpah seharusnya dapat menjamin ketahanan pangan suatu daerah karena kebutuhan pangan yang terpenuhi. Namun, provinsi penyumbang produksi padi di Indonesia belum dapat menjamin menjadi provinsi dengan ketahanan pangan paling baik. Hal ini disebabkan karena ketahanan pangan merupakan aspek multidimensi, sehingga ketahanan pangan suatu wilayah tidak dapat dicapai apabila hanya berfokus pada aspek ketersediaan pangan saja. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang mempengaruhi ketahanan pangan di provinsi penghasil padi di Indonesia selama periode 2019-2023. Metode yang digunakan yaitu analisis deskriptif, dan regresi data panel menggunakan metode Fixed Effect Model. Hasil analisis menunjukkan bahwa ketahanan pangan di provinsi penghasil padi Indonesia dipengaruhi oleh PDRB, jumlah produksi padi, IHK, jumlah penduduk, rumah tangga dengan akses air minum layak, dan pandemi Covid-19. Program Pemulihan Ekonomi Nasional (PEN) serta berbagai stimulus yang dijalankan Kementerian Pertanian telah mendukung peningkatan ketahanan pangan selama pandemi Covid-19., Abundant food availability should be able to guarantee food security in a region because food needs are met. However, the province that contributes the largest rice production in Indonesia cannot guarantee that it will be the province with the best food security. This is because food security is a multidimensional aspect, so food security in a region cannot be achieved if it only focuses on the aspect of food availability. This research aims to analyze the factors that influence food security in Indonesia’s largest rice-producing province during the 2019-2023 period. The analysis method used is descriptive, and panel data regression uses the Fixed Effect Model method. The analysis results show that food security in Indonesia's largest rice-producing province is influenced by GRDP, total rice production, CPI, population, households with access to adequate drinking water, and the Covid-19 pandemic. The National Economic Recovery Program (PEN) and various stimuli implemented by the Ministry of Agriculture have supported increasing food security during the Covid-19 pandemic.

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.
