Abstract

The evaluation of photosynthetic pigments composition is an essential task in agricultural studies. This is due to the fact that pigments composition could well represent the plant characteristics such as age and varieties. It could also describe the plant conditions, for example, nutrient deficiency, senescence, and responses under stress. Pigment role as light absorber makes it visually colorful. This colorful appearance provides benefits to the researcher on conducting a nondestructive analysis through a plant color digital image. In this research, a multispectral digital image was used to analyze three main photosynthetic pigments, i.e., chlorophyll, carotenoid, and anthocyanin in a plant leaf. Moreover, Convolutional Neural Network (CNN) model was developed to deliver a real-time analysis system. Input of the system is a plant leaf multispectral digital image, and the output is a content prediction of the pigments. It is proven that the CNN model could well recognize the relationship pattern between leaf digital image and pigments content. The best CNN architecture was found on ShallowNet model using Adaptive Moment Estimation (Adam) optimizer, batch size 30 and trained with 15 epoch. It performs satisfying prediction with MSE 0.0037 for in sample and 0.0060 for out sample prediction (actual data range -0.1 up to 2.2).

Abstract

Selection of varieties and number of seedlings per hole in rice plants is closely related to the shape of canopy, the rate of plant growth and the age of plant which determine the ability of plants to intercept and absorb solar radiation intensity. This research aimed to improve the Radiation Use Efficiency of rice by selecting plant canopies based on varieties and number of seeds per hole. Research was conducted from November 2015 to May 2016, in Landak Regency, West Kalimantan. A Split Plot Design with three replications was adopted to evaluate three varieties (Sembada-168, Inpari-30, and local varieties) as main plot, and the number of seedlings per planting hole (one, three, five, and seven seedlings per planting hole) as sub plot. Result showed that there was no interaction between varieties and the number of seedlings per hole to Radiation Use Efficiency (RUE) on rice. RUE on local variety was lower than Sembada-168 and Inpari-30. One seedling per hole had higher RUE than seven seeds with value of 3.36 and 2.17 % respectively. The number of seedlings showed that RUE of one and three seedlings per hole were higher than seven seedlings per hole.

Abstract

Padi (Oryza sativa L) menjadi komoditas yang berkontribusi dalam mendukung sektor pertanian di Indonesia. Salah satu daerah yang memiliki potensi besar budidaya padi adalah Kabupaten Nagekeo, Provinsi Nusa Tenggara Timur. Namun, terdapat tantangan utama dalam pengembangan potensi tersebut yaitu penurunan produksi padi akibat keterbatasan lahan. Oleh karena itu, tujuan dari penelitian ini adalah menerapkan sistem tanam jarak jajar legowo 2:1 yang dapat mengatasi permasalahan serta mengevaluasi dampaknya terhadap produktivitas dan keberlanjutan pertanian di wilayah tersebut. Metode ini tidak hanya meningkatkan penetrasi sinar matahari dan sirkulasi udara, tetapi juga memaksimalkan penggunaan teknologi pertanian modern dalam proses monitoring dan pengelolaan tanaman. Hasil implementasi tersebut menunjukkan adanya dampak positif yaitu peningkatan hasil panen serta mengurangi sumber daya pertanian. Hal ini ditunjukkan dari hasil panen padi yang meningkat setelah diimplementasikan sistem tersebut hingga 7 ton. Lalu, sistem tanam jarak jajar legowo dapat menurunkan penggunaan bibit padi hingga 50% yaitu dari 30 kg menjadi 15 kg. Adanya penelitian tersebut diharapkan dapat meningkatkan produktivitas pertanian di daerah Nagekeo.
