Abstract

Perubahan iklim merupakan ancaman bagi kegiatan budidaya pertanian termasuk budidaya tanaman padi Indonesia. Padi merupakan tanaman serelia yang sangat peka terhadap indikator perubahan iklim sehingga dapat menyebabkan perubahan hasil. Maka dari itu penelitian ini dilakukan untuk mengetahui besarnya perubahan curah hujan dan suhu serta korelasinya dengan produktivitas dan produksi padi di Kabupaten Garut. Penelitian dilakukan dengan metode deskriptif kuantitatif menggunakan analisis regresi, korelasi, dan klimogram yang masing-masing untuk mengetahui pola trend dari perubahan curah hujan dan suhu udara, pengaruh peruhaban curah hujan dan suhu udara terhadap produksi dan produkstivitas tanaman padi, serta kombinasi perubahan curah hujan terhadap suhu udara. Analisis korelasi dilakukan secara temporal selama periode 1982 hingga 2018 dan secara spasial untuk 42 kecamatan di kabupaten Garut. Data yang digunakan meliputi data iklim dan data budidaya tanaman padi yang diperoleh dari Dinas Pertanian, LAPAN, BPS, dan BMKG Kabupaten Garut pada tahun 1982 hingga 2018. Hasil penelitian menunjukkan bahwa di Kabupaten Garut terjadi trend peningkatan curah hujan sebesar 485 mm dan peningkatan suhu udara sebesar 0,2 oC serta pergeseran klimogram dari kiri ke arah kanan yang mengindikasikan perubahan curah hujan yang lebih besar dan perubahan suhu yang relatif kecil. Korelasi secara temporal antara curah hujan dengan luas panen dan produksi padi adalah signifikan dengan koefisien korelasi masing-masing sebesar 0,470 dan 0,385. Korelasi temporal antara suhu udara dengan luas panen, produktivitas, dan produksi padi adalah sigfinikan dengan koefisien korelasi masing-masing sebesar 0,424, 0,420 dan 0,423. Koefisien korelasi secara spasial antara curah hujan dengan produktivitas dan produksi padi di 42 Kecamatan Kabupaten Garut masing-masing berkisar antara 0,350–0,590 dan 0,390–0,794. Koefisien korelasi secara spasial antara suhu udara dengan produktivitas dan produksi padi masing-masing berkisar antara 0,572–0,648 dan antara 0,400–0,790. Fakta ini menunjukkan bahwa perubahan curah hujan dan suhu udara berpengaruh signifikan terhadap produktivitas dan produksi padi di Kabupaten Garut.

Abstract

The development of high-yielding hybrid maize is a strategic step to address global food demand amidst climate change. This study evaluates the agronomic performance of 14 maize genotypes—10 newly developed F1 hybrids and 4 commercial checks—under two planting densities (95,000 and 55,000 plants/ha) across three agroecosystems (lowland, midland, and highland). The objectives were to identify superior and adaptive genotypes and analyze genotype × environment interactions using AMMI and GGE biplot methods. Genotype G12 exhibited the highest yield (338.4 g/plant) at high density, especially in the highland, but showed poor stability. In contrast, G5 demonstrated consistent performance and stability across environments. This study highlights G5’s potential for broad adaptation and provides insights for breeding programs targeting maize productivity in diverse agroecosystems.

Abstract

Sumedang Regency is one of the regions in West Java with relatively low rice production compared to Karawang, Indramayu, and Subang Regencies. The low productivity of rice farming in Sumedang presents an opportunity to introduce functional food crops as an alternative source of income for rice farmers. This study aims to analyze the characteristics of rice farmers and their current farming practices, as well as to examine their interest and likelihood of cultivating hanjeli as an alternative crop. A descriptive statistical approach was employed, using survey and questionnaire methods distributed to 65 respondents in Buahdua District, Sumedang Regency. The results indicate that the majority of rice farmers are male, aged between 40–60 years, and married. Most have completed elementary school, do not own land, and cultivate less than 0.5 hectares. Their average farming income is IDR 1.4 million per month, with an average monthly production cost of IDR 1.8 million. The findings reveal that the interest of rice farmers in cultivating hanjeli remains low. Most farmers are not yet confident in the economic potential of hanjeli as a supplementary income source. However, a small number of farmers show a potential willingness to adopt hanjeli cultivation, suggesting that with proper intervention and market support, adoption could increase over time.

Abstract

Climate change occurred in Karawang Regency due to extreme weather events, which are included in the El Nino climate anomaly phenomenon. The existence of extreme weather events in Karawang Regency has decreased rice production, which is a climate-dependent crop. Based on this problem, a study was conducted to analyze the identification of extreme weather changes and correlation analysis of rice crops in Karawang Regency to see the magnitude of extreme weather changes and the influence of extreme weather elements on rice crops. The method used is a quantitative descriptive method by analyzing extreme weather changes, correlation analysis of extreme weather elements on rice plants (production, productivity, and harvest area), and correlation graphs of extreme weather elements with rice plants. Data was obtained from BPS, BMKG, and the Karawang Regency Agriculture and Food Security Office. The results showed that Karawang Regency experienced extreme weather changes due to climate change, namely an increase in the average maximum rainfall (1.78 mm), an increase in maximum temperature (0.76 °C), a decrease in minimum temperature (-0.57 °C), a decrease in wet spell for 3 days, and an increase in dry spell for 10 days. The impact of extreme weather change, namely the wet spell element, has a real significant correlation with a moderate level to a decrease in rice production and productivity.

Abstract

Job's tears is a cereal crop that has beneficial nutrients. Potassium is known to affect the growth and yield of cereal crops, but there has been limited study on whether potassium affects the nutrition and physical quality of Job’s tears seeds.  This study aimed to analyze the effect of K fertilizer on the nutritional content and physical quality of Job's tears seeds. This research was conducted from January to May 2024 at Ciparanje Experimental Field, Faculty of Agriculture, Universitas Padjadjaran, Sumedang, Indonesia. This experiment used the Randomized Block Design (RBD) method with six treatments and four replications. Various doses of K fertilizer (KCl) were tested, i.e., 0, 62.5, 125, 250, 375, and 500 kg/ha KCl. The measured nutritional content was the extraction rates of carbohydrate, protein, lipid, calcium, and potassium, while the physical quality was represented by the weight of husked grain, size of seeds, and seed hardness. Results showed that potassium increased the extraction rates of carbohydrate, protein, lipid, calcium, and potassium. Potassium also increased the weight of husked grain and size of seeds. A dosage of 500 kg/ha KCl resulted in the best nutrition, weight of husked grain, and size of seeds.
