Abstract

Tanaman pangan khususnya padi, selama ini ditanam lebih dominan pada lahan sawah, sedangkan pada lahankering pemanfaatannya belum optimal. Maka dinilai penting untuk meningkatkan pemanfaatan lahan kering untukusahatani padi gogo (Oryza sativa L.). Pemanfaatan lahan kering untuk padi gogo (Oryza sativa L.) dapat dilakukandengan memanfaatkan lahan perkebunan kelapa dalam (Cocos nucifera L). Tujuan dari penelitian ini yaitu untukmengidentifikasi VUB padi gogo yang adaptif pada lahan dibawah tegakan kelapa dalam. Penelitian ini dilaksanakanpada lahan milik petani seluas 2 ha di Desa Ataku, Kecamatan Andoolo, Kabupaten Konawe Selatan Propinsi SulawesiTenggara dan dilaksanakan pada musim kemarau (MK) bulan Mei sampai dengan Oktober 2018. Kajian menggunakanrancangan acak kelompok (RAK) dengan 4 ulangan (lahan petani sebagai ulangan) dengan luas masing-masing yaitu 0,5ha dan empat perlakuan varietas padi gogo yang terdiri dari 3 VUB (varietas unggul baru) padi gogo yaitu InpagoUnsoed 1, Inpago 8, Inpago 12 serta varietas Dodokero yang sering ditanam petani setempat yang digunakan sebagaipembanding. Hasil penelitian menunjukkan bahwa VUB Inpago 12 juga dapat beradaptasi pada lahan yang ternaungikelapa dalam (Cocos nucifera L.) yang ditunjukkan dengan pertumbuhan dan hasil panen lebih tinggi dari varietas padigogo yang lain dengan produktivitasnya mencapai 3,45 ton/ha GKG.Kata kunci : Lahan kering, Inpago 12, Konawe Selatan, Adaptif

Abstract

Plant secondary metabolites are unique sources for pharmaceuticals and food additives. Orange jessamine (Murraya paniculata) contains secondary metabolite that is beneficial to human health including lowering blood cholesterol levels, anti-obesity, and has the antioxidant capacity. Leaves of orange jessamine have several chemical constituents including L-cadinene, methyl-anthranilate, bisabolene, β-caryophyllene, geraniol, Carene, 5-guaiazulene, osthole, paniculatin, tannins, eugenol, citronelled, coumurrayin and coumarin derivatives. This study aimed to determine the correlation between leaf concentrations of N, P and K with leaf bioactive compounds following chicken manure application to the plants. The experiment was conducted at IPB Experimental Station at Cikarawang, Bogor (6o30' - 6o45' S, 106o30'-106o45' E) from March to November 2014 (250 m above sea level). The study used a randomized block design (RBD) with rates of chicken manure as a treatment, i.e. 0, 2.5, 5 and 7.5 kg per plant. Chicken manure was applied at 30 months after planting (MAP). Leaves were harvested by pruning the plants to a height of 75 cm above the soil surface. The results showed that the optimum rates of chicken manure to produce maximum fresh and dry leaf weight were 3.1 kg and 6.5 kg per plant, respectively. This rate was sufficient for leaf production at the first harvest (34 MAP) but was insufficient for the second harvest (38 MAP). K concentration of the leaves from different positions within the plant and leaf age positively correlated with leaf dry weight (P <0.01), but negatively correlated with total flavonoid content (P <0.01). Leaf P concentration was negatively correlated with dry weight of the 5th young leaves, or mature leaves from all positions. Leaf K concentration was categorized very high (3.59-4.10%), whereas leaf P concentration was high (0.28-0.29%) to very high (0.33-0.35%). The 5th mature leaves determined plant K requirements.Keywords: antioxidant, bioactive compounds, leaf position, organic, NPK leaf concentrations

Abstract

A bio-industrial farming system is a system that optimally manages and utilizes all biological resources, including biomass and organic agricultural waste, for the welfare of the community in an ecosystem in harmony. Integrating plants with livestock is one way to utilize all the waste produced from corn and cattle optimally, so it is a solution in providing organic fertilizer and feed during the dry season. This study aims to determine the perception, level of adoption, and adoption trend on the Bioindustrial Agriculture Model based on beef cattle integrated with corn at the farmer level. The research was conducted from August to December 2019 in Pangan Jaya Village, Lainea District, South Konawe Regency. Data was collected through interviews with 30 farmers with a structured question guide (questionnaire). Data were analyzed descriptively. The results showed that farmers positively perceive the technological innovation of corn and livestock. Farmers consider technological innovation in the Bioindustrial Agricultural Model profitable, uncomplicated, easy to try and see the results, does not conflict with local traditional values, and is by community needs. The level of adoption of technological innovations in the Bioindustrial Agriculture model is in the high category, reaching 67.14%. The adoption trend indicates that some technology components that farmers have not adopted will be adopted in the next growing season. Keywords: technological innovation, organic fertilizer, feed, and questionnaire
