Juwita Y, Karman J, Hutapea Y, Suparwoto S. 2020. Suitability of rubber plantation land intercropped with corn (Zea mays L) plants in Kelurahan Betung. Jurnal Lahan Suboptimal: Journal of Suboptimal Lands 9(1): 73-79.Rubber is one of the leading commodities of plantations in South Sumatra, especially in Banyuasin District. The opportunity for unused footpath land is a big potential in increasing farmers' income. In Betung Village, besides rubber, the community also raises livestock such as cows. This study aimed to provide information on the actual soil fertility status and see the suitability of the land in the study area when planted with corn plants, as well as the recommendations for the needed technology. The study used a survey method and the soil samples were taken using purposive random sampling method by determining the point diagonally and analyzed in the laboratory. The results of the study showed that the land suitability class at the location was according to the marginal with the limiting factors of water availability (rainfall) and nutrient retention (KB and pH). To obtain optimal corn production results, it is recommended to prepare a rainwater collection area and the addition of lime and organic matter.

Abstract

Scilab software is utilized for solving physics cases in two dimensional wave equations. This study aims to obtain a frequency mode simulation on the circular membrane so that it can display the wave pattern of each frequency mode. The method is to compare the simulation results with the normal mode circular membrane in each mode in to the theoretical calculation. The simulation has been done by utilizing the physics concept in a wave equation involving cos θ. The function of the wave equation is , assuming that r is the radius of the circle membrane. The value of the vibration  frequency mode in theoretical are f01 = (200.6 ± 2.0) Hz, f11 = (319.7 ± 3.1) Hz,  f21 = (428.5 ± 4.2) Hz. By using the Scilab program application, the results obtained show that the results frequency mode simulation f01, f11, dan f21 are similar to the normal mode in theoretical calculation. Thus, the simulation can be used to visualize waves of two dimensions in vibration and wave learning.

Abstract

The spectral induced polarization (SIP) method can provide apparent complex resistivity based on measurements of multi frequency. SIP method also can provide more detail information about physical properties of rocks and minerals because SIP can give spectral parameters or Cole-Cole parameters such as, changeability (m), time constant (?) and frequency dependence (c). An Experimental study in laboratory has been conducted to knowing the SIP response of some test sample. The measurement system is built with digital oscilloscope Pico ADC-100 as device for sampling the input and output voltage. Amplifier is used to doubled up the signal and input differential. The range frequency of measurement is 10?2 Hz - 103 Hz. Porouspot Cu ? CuSO4 is used to minimize the polarization at potential electrode. A Matlab listings is used to calculate the response of impedance and phase. The result from calibration that used the parallel circuit RC indicate that the measurement system was good. SIP response of porous model indicate that the response form an asymptotic resistivity, and the peak of phase is in the range frequency where the dispersion happen. The result also indicate that resistivity of small grain size model is larger than the big grain size model. Result from sample of mineralized rocks did not indicate a perfect SIP response, it is influenced by the contact between mineral and water was minimum.

Waluyo, Alkasuma, Susilawati, Suparwoto. 2012 Spatial Inventory of Potential Competitiveness Swamp Land for Agricultural Development in South Sumatra. J. Lahan Suboptimal 1(1):64-71. 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.

Suparwoto et al, 2019. The Growth and Production Three Rice Superior Varieties in Swampy Lands  at the Jambu Ilir Village, Ogan Komering Ilir District. JLSO 8(1):39-46.The assessment was carried out in Jambu Ilir Village, Tanjung Lubuk District, Ogan Komering Ilir Regency, South Sumatra, starting in the dry season of 2018. Varieties exhibited were 2 superior varieties  and 1 comparative variety, Mekongga. The aim of the study was to obtain information on the growth and production of Inpari 30 and Inpara 8 varieties that were adaptive and had high production on lebak lands. The study was designed by observation method, spacing of legowo 2: 1 (50x25x12.5 cm), seedling age 35 days after seedling, 2-3 seeds / holes. The dosage of fertilizer used is 150 kg Urea, 100 kg SP-36 and 100 kg KCl / ha. The variables observed were: plant height, number of productive tillers, number of grain per panicle, number of filled grains per panicle, and grain yield per ha. The data obtained was arranged in tabulation and analyzed by statistical tests, namely the test of the mean value (test-t). The results showed that the plant height of the varieties exhibited was classified as low to moderate with the number of productive tillers classified as moderate. Inpari 30, and Inpara 8 can adapt well in lebak lands with a production of 5.1-5.3 tons GKP / ha higher than Mekongga as a comparison variety and are highly favored by farmers.
