Laser inframerah sering diaplikasikan pada tanaman, salah satunya pada tanaman padi. Padi (Oryza sativa L.) merupakan tanaman yang hasil panennya menjanjikan untuk masyarakat Indonesia, namun tidak semua padi dapat dipanen dan tidak semuanya dapat dipasarkan. Karakteristik padi yang baik untuk dipasarkan dan dikonsumsi terdapat pada tinggi dan jumlah anakan produktif tanaman padi sesuai dengan perlakuan tertentu. Tujuan penelitian ini adalah menganalisis pengaruh laser inframerah terhadap tinggi dan jumlah anakan produktif tanaman padi. Penelitian ini dilakukan pada sawah seluas 5 m2 di Desa Ngoran, Kecamatan Nglegok, Kabupaten Blitar. Tanaman padi pada penelitian ini berjenis Inpari 13 yang berumur 48 hari setelah sebar (HSS). Karakteristik data panjang gelombang infrared memiliki rata-rata sebesar 497,53 micrometer serta pada data tinggi batang padi memiliki rata-rata sebesar 56,845 cm. Pola hubungan antara panjang gelombang infrared dengan tinggi batang padi menunjukkan korelasi yang positif. Artinya, jika panjang gelombang infrared bertambah maka tinggi batang padi akan bertambah. Jika panjang gelombang infrared bernilai 0 maka tinggi batang padi sebesar 55,226 cm, dan jika panjang gelombang infrared naik 1 satuan maka tinggi batang padi akan naik sebesar 0,03. Pengujian asumsi residual IIDN residual data tinggi batang padi memenuhi asumsi identik, independen, dan berdistribusi normal

BIOKIMIAWI RIZOSFER BIBIT ROTAN PADA PEMUPUKAN NITROGEN DARI SUMBER BERBEDA
Full text linkRoot and soil interactions will alter the biochemical status of the rhizosphere, the acquisition of nutrients and impacted to plant growth. The biochemical of the rhizosphere is strongly influenced by the agriculture input e.g. fertilizer, herbicides and farm management system. Application of fertilizers, their effects are robust and difficult tobe quantified. The effect of fertilizer on the biochemical status rhizosphere and plant growth is different depending on the type of fertilizers, growth media, plant species, and also the environment condition, while the effect on plants will be specific to each plant. This research investigated on the effect of N inorganic fertilizer inputs from two sources namely Urea (CO(NH2)2) and Ammonium Sulfate or ZA ((NH4)2.SO4), and different fertilization method (homogenous and localized). Experiments showed application of N-Urea and N-ZA fertilizers reduced the rhizosphere pH until 1,4 point. However, acidity of the rhizosphere reduced microorganism colonies and respiration rate

Full text linkBiodiversity is an important part of the agricultural ecosystem (agroecosystem) and diversity is determined by the environment and the application of pesticides in the field. Research on the diversity of arthropods in shallot cultivation with different intensities of pesticide application aims to determine the types and populations of arthropods in shallot cultivation on land with different intensities of pesticide application. The research was conducted in the village of Soulowe, which is the center of shallot plants in Sigi Regency, with a massive and intensive application of pesticides, from December 2019 to March 2020. Sampling was carried out using absolute methods (direct observation) and relative methods (Pitffal Traf and Jaring Ayun). The results of the identification carried out in the Unisa and Untad Palu laboratories found that the diversity of arthropods in low-intensity areas of pesticide application was more than that of medium and high applications. There are 7 orders and 13 families, namely Oxyopidae, Grillotalpidae (Ordo Araneae), Scarabaeidae, Coccinellidae (Order Coleoptera), Forficuloidea (Order Dermaptera), Agromyzidae, Muscidae (Order Diptera), Formicidae, Apidae (Order of Hymenoptera), Noctuidae (Order of Hymenoptera) and Acrididae, Gryllidae andTotigonidae (Order Orthoptera). The level of diversity, evenness and family wealth as well as the abundance of arthropod individuals were higher in land with low pesticide application intensity than medium and high pesticide application
