Oil palm Plantation at Muaro Jambi, Jambi province already aged over 25 years, so these plants are not productive anymore and needs to be rejuvenated. By doing rejuvenation means farmers will lose income while waiting for the palm oil crop production for 3-4 years. Intercrop between oil palm plantations have great resulted in improved land productivity, increase farmers' income as well as the main crop of palm maintained. Technological innovation between plants can be carried out on an oil palm plantation aged 1 to 3 years or before the plant produces. The aim is to optimize land use oil palm replanting with horticultural crops through the provision of organic matter and MPHP (Silver Black plastic mulch). The activities carried out in Mekarsari Makmur Village Muaro Jambi District. Horticultural crops that are cultivated eggplant, beans, bitter melon, squash and cucumber. The draft assessment used was a factorial randomized block design with two factors, namely: MPHP (MPHP Without and With MPHP) and the provision of organic material (Without organic fertilizers, Manure, Compost and manure + compost). For all commodities, the highest production was obtained at treatment MPHP use and manure, ie 20.9 tonnes of beans/ha, 8.99 tons of cucumbers/ha, 5.95 tons of squash/ha, 1.17 pare ton/ha and 6 , 8 tons of eggplant/ha

Lindiana, et al.Â Rice Cultivation Images by Local Farmers in Pemulutan District, Ogan Ilir, South Sumatra. JLSO 5(2):153-158.Â Plans and efforts in increasing rice productivity at riparian wetlands can be commenced by introducing relevant technologies; however, the selected technologies should be based on real needs or problems faced by local farmers. As a pre-requisite, if the needs and problems are not comprehensively understood, government intervention to introduce new technology may not be effective since the technology may not be relevant or affordable to local farmers. Objectives of this research are to analyze characteristics of the wetlands, farmerâ€™s adoption capacity, and technological preferences. The research was conducted in five villages at Pemulutan District. Qualitative Grounded Theory and Quantitative Survey were employed through dialogues with 100 local farmers.Â Results of the research indicated that any effort to increase riparian wetland productivity should consider the unpredictability of flood occurrences and prolonged drought. These unfavorable conditions have limited local farmers to only grow rice once per year. Local farmers were almost solely depending on rice and cultivation of other crops were rarely observed, except limited vegetables grown on elevated border of paddy fields.

Heriyanto et al, 2018. Analysis of the Production Factors of the People's Palm Oil According to the Land Typology in Indragiri Hilir Regency, Riau Province. JLSO 7(1):14-25.Â Palm oil commodities are one of the plantation sub-sector commodities that increase the income of farmers and the community, provide processing industry raw materials that create added value. The land cultivated by independent oil palm farmers consists of land land, tidal peatlands, coastal peatlands and coastal land. The difference in typology of this land will contribute to different production. The research aimed to analyze the oil palm production and the dominant factor affecting oil palm production according to the typology of land in Indragiri Hilir Riau Province. The data were analyzed using descriptive statistics and built multiple regression models with the dummy variable method of Ordinary Least Square (OLS). The results of the study showed that the production of oil palm cultivation on land is the highest compared to the typology of tidal peatland, coastal peat and coastal land. The dominant factors affecting palm oil production in Indragiri Hilir Regency were the amount of fertilizer use, labor, age of plants, herbicides and dummy typology of land. In order to obtain optimal production, this study recommended doing oil palm farming in accordance with the correct cultivation techniques in accordance with the characteristics of land typology. Besides that the use of balanced fertilizer (elements of N, P, and K) in accordance with the recommended needed to be applied.

Nugraha et al, 2019.Â Solubilization of Inorganic Phospate by Burkholderia spp. Associated with Oil Palm Rhizosphere in Mineral Acid Soil. JSLO 8(1):86-93.Phosphate Solubilizing Bacteria (PSB) play important role by enhancing phosphate availability bounded with Al3+ orÂ Fe3+ in acidic soils to oil palm plants through release the inorganic phosphate by enzyme or organic acids solubilization. The aims of this study were to isolate of PSB from oil palm rhizosphere and to conduct a comparative analysis of the solubility inorganic phosphates source by selected PSB. The ability of 15 selected PSB to grow and solubilize aluminum phosphate (AlPO4) and iron phosphate (FePO4) was examined and identified. The highest phospate solubilising efficiency showed K3.1 isolate with phosphate solubilization index 3.2 on NBRIP media. Quantitative analysis revealed that isolate K3.1 solubilized 53.52 mg/mL phosphate in 5 days after being inoculated in AlPO4 containing liquid medium, isolate A4 solubilized 63.45 mg/mL phosphate in 5 days after being inoculated in FePO4 containing liquid medium accompanied by a decrease in pH of the growth medium. Based on the 16s rRNA gene sequence analysis, isolate K3.1 and A.4 were closely related to Burkholderia arboris and Burkholderia gladioli. This potential isolates can be used in order to make oil palm crops more sustainable especially on marginal soil with low pH and less dependent on inorganic P fertilizers.Â

Corn plant is suitable to cultivate on suboptimal land due to itâ€™s resistance to acid and dry soil. The objective of the research was to determine the effect of time soaking corn kernels and addition of water to corn flour on characteristics of instant corn rice. Corn that is used is from the farmers of Arisanjaya village (the area of suboptimal land agriculture). The research used a Factorial Completely Randomized Design with two treatment factors and three replications. The observed treatment factor was soaking time (A1: 6 hours, A2: 12 hours, A3: 24 hours) and the addition of water (B1: 80%, B2: 90%, B3: 100%). Observed parameters were physical (color, texture and length of serving), chemical (moisture, ash) and sensory characteristics with hedonic test (texture, color and flavor). The results showed that the soaking time had significant effect on lightness, chroma and ash content of instant corn rice. The addition water had significant effect on the chroma of instant corn rice. The interaction between the soaking time and addition of water had significant effect on the chroma of instant corn rice. The treatment A1B3 (6 hour soaking time and the addition of water 100%) was the best treatment with the average color values (49.77% lightness, 21.40% chroma, 65.200 hue), 76.73 gf cooked corn rice texture, 9.67 minute length of serving, 4.36% moisture content, 1,01 % ash content, the average value of hedonic test (2.20 texture, 2.56 color, and 1.88 flavor).

Waluyo, Alkasuma, Susilawati, Suparwoto. 2012Â Spatial Inventory of Potential Competitiveness Swamp Land for Agricultural Development in South Sumatra. J. Lahan Suboptimal 1(1):64-71.Â Swampy marsh land has great competitive advantage for farmland development.The purposes of this study were 1)to identify the spread of potential swampy marsh land for food crops in major production centers; 2)to understand thecontent, quantity,and distribution of minerals essential for health in the low lands of South Sumatra. Data were collected through some surveys using transects (toposequen), including delineation of maps, flooding/ground water, state of the microrelief, soilbase material, land use, and land surface condition. Ground observations were based on the Soil Survey Manual. The results indicated that Sungai Pinang and Rantau Panjang has three types of swampy land, namely shallow swampy marsh, mid marsh low lands, and swamps in the low lands. Swampy marsh as the potential competitiveness for its antioxidant mineral deposit (Fe, Mn, Cu, Zn, and Se) can produce good functional food products such as Padi seputih, Pelita Rampak, Ketan Sinde, Padi Petek. These varieties have considerably high antioxidant mineral. Therefore, the use of swampyland must be directed. Shallow and intermediate wetlands can be used for rice, pulses and vegetables whereas deep wetlands are suitable for fishing.
