Abstract

Rice (Oryza sativa L.) is one of the main food commodities in Indonesia and has a strategic role in national food security. High quality rice production is a major factor in meeting the increasing consumption needs of the community. However, agricultural conditions in Indonesia still face various challenges, especially in rainfed rice fields which are highly dependent on rainfall and often experience problems in crop production. This research was conducted in Prabu Menang Village, East Merapi District, Lahat Regency, South Sumatra Province, from January to April 2024. The method used was quantitative research with a split plot design. The main plot was a combination of fertilizers consisting of three treatments: (1) NPK (300 kg/ha), Urea (150 kg/ha), and LOF (Liquid Organic Fertilizer) (25 ml/L) ; (2) NPK (300 kg/ha) and Urea (150 kg/ha) fertilizer; and (3) LOF (25 ml/L). The subplots consisted of two rice varieties, Nutri Zinc and Inpari 32, so there were 6 treatment combinations repeated 4 times, resulting in a total of 24 units experimental . This study aimed to analyze the effect of fertilizer combinations on the growth and yield of Nutri Zinc and Inpari 32 varieties in rainfed fields. The results showed that the combination of fertilizers had significant effect on plant height and number of tillers. Inpari 32 variety was with superior higher plant height and more tillers than the Nutri Zinc variety. The combination of NPK, Urea, and LOF fertilizers with the Inpari 32 variety produced the highest productivity of 4.67 tons/ha, while Nutri zink variety with the same fertilizer is 4.41 tons/ha. The combination of NPK and Urea fertilizers with the Inpari 32 variety is 4.60 tons/ha and Nutri zink variety is 4.35 tons/ha. The use of LOF alone resulted in a lower number of tillers and productivity, 3.92 tons/ha for Inpari 32 variety and 3.66 tons/ha for Nutri Zink variet.

Abstract

Kemampuan berbicara merupakan salah satu dari empat keterampilan berbahasa. Berbicara merupakan keterampilan produktif dalam artian pembicara menghasilkan bunyi bahasa dan komunikasi dalam dua arah. Pembicara dan pendengar dapat menegosiasikan arti dari apa yang mereka katakan. Era industri 4.0, kemampuan berbicara dan mengemukakan sebuah masalah di depan umum sangat penting karena informasi yang didapatkan tidak lagi terbatas. Oleh karena itu, untuk menghindari kesalahpahaman terhadap isi informasi, diperlukan kemampuan berbicara di depan umum. Kemampuan tersebut membantu seseorang untuk mencari dan memahami informasi dengan benar. Selain itu, kemampuan berbicara di depan umum juga mengajarkan cara meyakinkan orang lain untuk mendapatkan informasi yang benar dan berguna untuk yang membutuhkan. Tulisan ini membahas tentang keterampilan berbicara mahasiswa di depan masyarakat Desa Burai mengenai pengelolaan sampah di daerah rawa. Para mahasiswa didorong untuk melatih kemampuan berbicara mereka dengan topik permasalahan mengenai pembuangan sampah masyarakat di daerah rawa melalui teknik wawancara. Metode kegiatan dimulai dari kegiatan pendampingan oleh dosen pendamping dimulai dengan pendahuluan, pemberian materi, dan evaluasi kegiatan. Hasil yang didapatkan bahwa mahasiswa dapat meningkatkan kemampuan berbicara di depan umum dengan rasa percaya diri dan termotivasi, tanpa harus takut mengemukakan pendapat atau butir pertanyaan yang dapat menyinggung masyarakat. Kata kunci: Desa Burai, kemampuan berbicara, rawa, wawancara

Abstract

Padang City is the largest city on the west coast of Sumatra Island and the capital of West Sumatra Province, Indonesia (BPS Padang City, 2024). Surrounded by hills at an altitude of 1,853 meters above sea level, Padang covers an area of 1,414.96 km². The city had a population of 928,541 in mid-2023, comprising 11 sub-districts, 104 villages, and 19 small islands. Padang is the core city of the Palapa metropolitan area. This study aims to determine the comparison of surface temperatures in Padang City from 2014 and 2024. This research method consists of image data obtained from the USGS Explorer site consisting of Landsat 8 satellite images dated August 15, 2014 and January 23, 2024 and Band 10 and Band 11, and the administrative map of Padang City obtained from the boundaries of the Regency/City of the Population and Civil Registration Office (Dukcapil) of Padang City. The results of this study are that the land surface temperature in the Padang City area has increased over a period of ten years along with the increase in built-up land and land use due to human activities. The increase in built-up land surface temperature and land use is spatially distributed in eleven sub-districts with an average temperature of >25.9 OC. In line with the increase in land surface temperatures caused by changes in temperature class ranges, nine areas in Padang City have a high potential to become sources of urban heat islands: Koto Tangah, Nanggalo, Kuranji, North Padang, West Padang, East Padang, South Padang, Lubuk Begalung, and Bungus Teluk Kabung Districts. Spatially, these nine areas are adjacent to each other or connected to one another.
