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

Negara Indonesia ialah negara yang berkembang pada sektor agraris. Pembangunan pertanian di Indonesia diarahkan pada sasaran utama yaitu peningkatan produksi pangan rakyat yang terus meningkat sejalan dengan pesatnya pertumbuhan penduduk. Satu diantara cara untuk meningkatkan produksi ialah dengan meningkatkan kesuburan tanah. Tanah yang subur semakin berkurang di Indonesia, lahan yang tersedia sudah berkurang kesuburannya karena sudah dimanfaatkan dalam waktu yang cukup lama dengan pengguanaan pupuk anorganik yang berlebihan. Satu diantara cara untuk memperbaiki kesuburahan lahan ialah dengan menggunakan sistem pertanian organik. Tujuan penelitian ini ialah untuk mengetahui pengaruhi pemberian dosis pupuk hijau paitan (Tithonia diversifolia) dan krinyu (Chromolaena odarata) guna meningkatkan hasil tanaman brokoli. Penelitian dilaksanakan di kebun percobaan Cangar Fakultas Pertanian. Penelitian  menggunakan Rancangan Acak Kelompok Faktorial yang terdiri dari 2 faktor dan 3 ulangan. Faktor pertama yakni dosis pupuk hijau paitan dan faktor kedua yakni dosis pupuk hijau krinyu. Data yang diperoleh dianalisis menggunakan analisis ragam (ANOVA), jika terdapat pengaruh nyata dilanjutkan dengan uji BNT 5%.  Hasil penelitian menunjukkan bahwa perlakuan dosis pupuk hijau paitan dosis 6 ton ha-1 dapat meningkatkan penambahan jumlah daun, luas daun, index luas daun, bobot segar, bobot kering. Pada parameter panenl dosis pupuk hijau paitan juga meningkatkan diameter bunga dan bobot segar bunga tanaman brokoli yakni 10, 44 cm per tanaman dan 213 g per tanaman.

Abstract

Roses is one of popular and widely cultivated commodities in Indonesia. Based on usefulness, roses can be classified into cut flowers, potted flowers and garden elements. Roses used as garden ornamental plants because it is able to improve aesthetics of garden and create comfortable atmosphere for visitors garden. The purposes of the research was to study the effect and obtain the level of pruning and appropriate concentration of foliar fertilizer for growth and flowering of roses. The hypothesis of the research were to get  influence and get right level of pruning and foliar fertilizer concentration that can increase growth and flowering of roses. The research was conducted in March to June 2018 at Venus Orchid and Nursery, Malang. Split Plot Design with 3 repetition, foliar fertilizer as main plot and prunning as sub plot. Parameters observed included growth and flowering roses. Growth variables include number of shoots (shoots), length of branches (cm), time of budding (hsp), number of leaves (strands), and leaf area (cm2). Flowering variables include the number of flowers (flower per plant), the length of the stalk flower (cm), the diameter of the flower (cm), time of flowering (hsp), time of blooming (hsp), and vase life (day). The results showed that 1500 ppm concentration of foliar fertilizer with hard pinch 1 pruning was able to increase 34.47% of the branch length, accelerate the emergence of branch buds 70 days, increase 3.66 flowers and accelerate 14.16 days when flowering on roses compared to treatments without pruning and foliar fertilizer

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.) adalah tanaman pangan pokok sebagian besar masyarakat Indonesia. Salah satu faktor penghambat yang mengurangi hasil padi hingga 50% adalah gulma. Saat ini gulma dikendalikan dengan cara manual, mekanis dan kimiawi yang membutuhkan tenaga kerja tinggi dan tidak ramah lingkungan. Sebagai alternatif, Sistem Padi Kompleks yang menggunakan itik untuk mengendalikan gulma dapat diterapkan. Tujuan penelitian yaitu untuk mempelajari pengaruh jumlah itik terhadap pertumbuhan dan hasil padi varietas Rajasa-01 serta pengaruhnya terhadap gulma. Penelitian dilaksanakan bulan Januari sampai Mei 2022 di Desa Sukorejo, Gondanglegi, Kabupaten Malang, Jawa Timur. Penelitian disusun menggunakan Rancangan Acak Kelompok 6 kali ulangan; D0: penyiangan manual; D1: 1 ekor per 20 m2; D2: 2 ekor per 20 m2; D3: 3 ekor per 20 m2. Variabel meliputi tinggi tanaman, jumlah daun, jumlah anakan, jumlah anakan produktif, Summed Dominance Ratio, berat kering gulma, berat gabah per rumpun, berat gabah kering panen per m2, berat kering total tanaman, dan berat 1000 butir. Data ditabulasi dengan Microsoft Excel, dianalis dengan tabel Sidik Ragam, dan menggunakan Beda Nyata Terkecil. Hasil penelitian menunjukkan bahwa semua variabel berbeda nyata kecuali berat 1000 butir. Penggembalaan itik sebanyak 2 ekor per 20 m2 menghasilkan gabah kering panen sebesar 620,51 g.m-2, sehingga meningkatkan produksi padi varietas Rajasa-01 hingga 36,65% daripada perlakuan penyiangan manual, 25,22% daripada penggembalaan itik 1 itik per 20 m2, dan sebesar 21,86% dibandingkan penggembalaan 3 itik per 20. Penggembalaan itik sebanyak 1000 ekor per hektar dapat mengurangi kerapatan populasi gulma dan waktu muncul gulma.

Abstract

AbstractThis experiment aims to know the solar energy efficiency of four clones of cocoa that cultivated under three different shading plants. This experiment has been done from September until December 2013 located at Kaliwining Experiment Farm with characteristic 45 m above sea level, soil type is low humic gley, soil texture is silty clay loam, and climate classification type D based on Scmidht and Fergusson Classification. This experiment used Nested Design as Experimental Design with species of shading plant as main plot which are Teak (Tectona grandis L.), Krete (Cassia surattensis (Burm.) F.), Lamtoro (Leucaena leucocephala L.) and Cocoa clones as sub plot which are Sulawesi 1, Sulawesi 2, KKM 22, KW 165. The observation of solar energy efficiency consists of daily solar radiation intensity, solar radiation intensity above plant, solar radiation intensity under plant, and also plant total dry weight. The experimental result showed that there is differences (heterogenity) between shading location based on homogenity test by Bartlett Method. There are some interaction between the kind of shading plant and clones in parameter of interception efficiency, absorbtion efficiency, the efficiency of solar energy that caught by plant, and solar energy conversion efficiency. The efficiency of solar energy that caught by plant will affect the solar energy conversion efficiency with R2 = 0,86.  Keywords : Solar Energy Efficiency, Cocoa Clones, Shading Plant, Nested Design, Bartlett Method
