“…Dibandingkan dengan penelitian lain, bobot gabah hampa pada penelitian ini tergolong tinggi. Telah banyak peneliti yang mengkaji penyebab tingginya gabah hampa pada tanaman padi yakni varietas yang digunakan (Dulbari et al, 2018), seringnya kejadian hujan pada saat pembungaan (Purwono et al, 2021), tingkat ketersediaan N (Chairunnisak et al, 2018), serangan penyakit (Subiandi et al, 2019), kekeringan (Tubur et al, 2012;Antralina et al, 2019), ketidakseimbangan sink-source (Ichsan et al, 2021), dan suhu tinggi (Chen et al, 2017).…”

Penelitian ini dilakukan untuk mempelajari pengaruh jarak tanam dan dosis nitrogen (N) terhadap pertumbuhan dan hasil padi ketan grendel (Oryza sativa L. var glutinosa). Penelitian dilaksanakan di Desa Jatisari, Karawang, Jawa Barat yang berada pada ketinggian 25.6 m dpl pada Januari-Juni 2022. Penelitian menggunakan rancangan split plot dengan dua faktor yaitu jarak tanam sebagai petak utama (20 cm x 20 cm, 25 cm x 25 cm, 30 cm x 30 cm, dan 40 cm x 40 cm) dan dosis N sebagai anak petak (0, 45, 90, 135, dan 180 kg N ha-1). Kombinasi perlakuan diulang sebanyak 3 kali. Hasil penelitian menunjukkan bahwa jarak tanam 40 cm x 40 cm dan dosis N 180 kg N ha-1 merupakan kombinasi terbaik karena dapat meningkatkan tinggi tanaman, jumlah anakan, warna daun, jumlah anakan produktif, bobot kering sampel, bobot gabah hampa, jumlah bulir per malai, dan hasil ubinan (GKP) yang lebih tinggi dibandingkan dengan perlakuan lain. Dengan demikian, jarak tanam dan dosis tersebut direkomendasikan untuk dikaji lebih lanjut dalam rangka mendukung produktivitas padi ketan grendel. Kata kunci: dosis rekomendasi, jarak tanam, komponen hasil, pemupukan nitrogen

“…Elevated temperatures, for instance, can negatively impact yields by reducing pollen fertility [13], diminishing the weight of a thousand grains by 4.6%, and decreasing the harvest index by 20% [14]. Exposure to wind and rain can similarly influence rice production by causing paddy plants to lodge [15], thereby affecting grain weight and increasing the proportion of empty grains [16]. Numerous studies have demonstrated that integrating meteorological data with satellite imagery enhances the performance of crop yield prediction models [17] [18].…”

In the era of modern agriculture, satellite imagery has been widely used to monitor crops, one of which is paddy. This paper tries to describe the vegetation indices, climate, and soil index features related to paddy plants and curates a collection of satellite imagery on the Google Earth Engine (GEE). This paper reveals how GEE can be used to collect and process multimodal satellite imagery to form a precision agriculture dataset. The objective of this study is to establish a comprehensive precision agriculture dataset by leveraging multimodal satellite imagery to monitor paddy crops. The data collected as a dataset originates from 306 locations in Karawang Regency, Indonesia, during the 2019-2020 period. In the first step, we identify the relevant features essential for paddy crop analysis. Subsequently, we carefully select image collections within GEE based on these features. Afterward, we perform data acquisition and necessary preprocessing through the Google Colab environment. The results showed that satellite imagery from Sentinel-2 outperforms Landsat 8 in terms of spatial and temporal resolution. Apart from that, the generated dataset successfully captures the growth patterns of paddy plants.

“…The negative impact of climate change on crops generally through the changing rainfall and strong wind in annual crops (Dulbari et al, 2021;Purwono et al, 2021;Agusta et al, 2022), heavy rainfall and temperature in perennial crops (Santosa et al, 2018;Sianipar, 2021). Gunathilaka and Tularam (2016) noted that the adverse effect of climate change on the tea industries is increasing temperature, drought, and excess rainfall.…”

Climate change, i.e., changing rainfall refers to drought and excess rainfall, is known to affect the growth and yield of tea production in many regions. However, research on the impact of climate change on tea plantations in Indonesia is still limited. The study aimed to evaluate the impact of changing rainfall on the productivity of tea plantation at Cianjur, West Java. The data was collected from interviews, field data, and company records from April to July 2022. The results showed that changing rainfall of both limited rainfalls during El Nino and excess rainfall during La Nina affected the tea production. Annual tea productivity declined during both climatic events. Shortage of water during El Nino primarily reduced crop growth, while excess rainfall during La Nina reduced the capacity of tea pickers and increased labor for crop maintenance. Failure to adapt to the direct and indirect impacts of climate change could contribute to declining tea production in Indonesia. Thus, comprehensive action is needed including capacity building in human resources, water management, and microclimate adaptation such as shading plants and tolerant clones to sustain tea production under climate change events.
