Abstract

Sugarcane (Saccharum Officinarum L) is one of the potential plants and has sufficient economic values with an important role as a source of economic growth in Indonesia. Sugarcane land suitability index in Arasoe, Bone. Sugarcane plantations using a parametric approach and analyzing the relationship between land characteristics and sugarcane production at the study location. This research was performed in 9 (nine) unit lands produced from overlapping slope maps, soil type maps, and PT Arasoe sugarcane map with sugarcane production high (> 50 tons/ha), moderate (40-30 tons/ha), and low (<30 tons/ha). This research took place between July - November 2019. To calculate the land suitability index (IKL) used the parametric method with the Khiddir equation (1986), to evaluate the relationship between IKL and sugarcane productivity using Pearson correlation analysis. Research shows that the value of IKL ranges from 31.56 to 42.43 and classified according to marginal (S3) with limited factors are climate and base saturation. The relationship between IKL and sugarcane productivity was statistically significant as evidenced by the Pearson correlation coefficient r> 0.4 (p <0.05) which showed that along with the increase in IKL, sugarcane productivity also increased significantly.

Abstract

The soil susceptibility increases in line with decreased soil stability and the ability of soil to pass water which, affected by the soil's physical characteristics. The research aims to analyze the physical properties of soil that affected landslide events in South Makale. This research using the method of comparative analysis by comparing the soil characteristic in the landslide and non-landslide areas. The soil has 6 class textures namely silt loam, loam, clay loam, silty clay loam, silty clay, and sandy clay loam. Soil Permeability ranges 0.22-6.98 cm/h (slowly-rather quickly). On the non-landslide areas, soil permeability is relatively low with values of 0.55 to 0.72cm/hour. The soil liquid limit value on the landslide area reached the value max of 67.7%, with the plasticity index value max 21.77%. The liquid limit in the non-landslide area reached a value max of 45.0% with a plasticity index value max 8.56%. Soil with silt and clay fraction dominant have a relationship with the landslide event. Soil with the silt and clay fraction dominant causes a decrease in the permeability value and affects the increase in liquid limit value and soil plasticity index.

Abstract

Oil palm (Elaeis guineensis Jacq) is one of the important commodities in Indonesia and has bright prospects for development. The increase in demand for palm oil per year continues to increase, this is evidenced by the increase in CPO production from 2011 to 2015 increased by around 5.38 to 8.42 percent per year. The increase in oil palm production is allegedly related to weather effects such as rainfall in a certain period. This research is indispensable as a basis for predicting and evaluating the production and fresh fruit of oil palm in relation to climate elements. The dependent variable data used in this study were primary data on the production of fresh fruit bunches for oil palm PTPN Wilayah XIV as Asera plantation unit. While the independent variable data used are air temperature, rainfall, and solar radiation (2013-2015) which are analyzed using the correlation test by analyzing the degree or closeness of the relationship between climatic factors including air temperature, rainfall, and solar radiation with oil palm production in North Konawe Regency and knowing the form of the relationship between the two variables using a scatter diagram. The results of the analysis show that temperature and oil palm production have a very strong positive relationship with a correlation coefficient of 1.0. Rainfall and oil palm production have a moderate positive relationship with a correlation coefficient of 0.6, solar radiation and oil palm production in North Konawe have no relationship during 2013-2015, but solar radiation is closely related to rainfall and temperature variables.

Abstract

As the population continues to increase in an area, land requirements will also increase. The consequence will be that the population pressure on agricultural land is quite large and will ultimately reduce the output of agricultural production in the region. If this is allowed to continue it is not impossible that the production is not proportional to the food needs of the population. Thus it will cause the carrying capacity of agricultural land to be smaller.The purpose of this study is to analyze the effect of the carrying capacity of agricultural land (rice fields) on production results in Waeapo District, Buru Regency. The research method used was survey research with quantitative descriptive methods. Quantitative descriptive is an activity that is directed to measure or explain carefully certain phenomena or symptoms that are intended to test the truth in the field. The results showed that there were 3 (three) villages namely Savanajaya Village, Waetele Village and Waenetat Village whose carrying capacity of agricultural land (paddy) experienced a deficit (exceeded), while 3 (three) other villages namely Waekerta Village, Waekasar Village and Desa Wanareja carrying capacity of agricultural land has a surplus (sufficient). Thus there is a balance between land needs and the ability of land to provide food (especially rice) to meet the needs of residents in Waeapo District

Abstract

ABSTRACT The implementation of Jeneberang watershed management is a watershed management priority plan that has been determined by the Government. However, there is no common ground and commitment between the government and all stakeholders, so there are still various problems in the upstream Jeneberang watershed. This study aims to determine the management strategy in the upstream area of ​​the Jeneberang River Basin and to analyze the factors that determine the success of the Jeneberang watershed management strategy. This research uses qualitative and quantitative methods with descriptive analysis techniques and SWOT-AHP analysis. The results of this study explain that the Jeneberang watershed is in the critical category and a priority national watershed in handling. So that it requires the handling of all stakeholders to work together. All stakeholders have the same management goal, which is to maintain sustainability, balance the ecosystem, and help community welfare. However, due to lack of coordination between all stakeholders and budget constraints. The results of the SWOT – AHP analysis show that the success factors in managing the Jeneberang watershed are: 1. Requiring commitment of all stakeholders and providing incentives, education, opening jobs, training and assistance to communities who maintain the sustainability of the upstream Jeneberang watershed. 2. Maximizing and prioritizing the management of the Jeneberang watershed so that erosion and flooding does not occur. 3. Land conversion occurs around the Jeneberang watershed so that it requires intensive handling and supervision from all parties who manage the Jeneberang watershed.

Abstract

Pupuk organik akan menjadi pilihan pupuk yang paling potensial dan ramah lingkungan untuk pertanian masa depan. Diversifikasi pupuk organik dilakukan dalam rangka memanfaatkan sumber daya alam yang melimpah dan dapat bernilai ekonomis yang tinggi. Salah satu sumber daya alam yang cukup melimpah adalah limbah padat tambak udang superintensif yang memiliki dampak yang buruk terhadap lingkungan apabila tidak dikelola dengan baik. Namun dibalik itu limbah tersebut dapat dimanfaatkan menjadi pupuk organik melalui pengomposan. Penelitian ini bertujuan untuk mentransformasi limbah tambak udang menjadi pupuk organik. Penelitian ini dilaksanakan selama dua bulan yakni dari bulan maret sampai mei 2020. Pelaksanaan penelitian dimulai dengan pengambilan sampel limbah tambak udang, analisis awal sampel, pengeringan, penghalusan, pencampuran bahan pengomposan, pengomposan, panen, analisis akhir sampel yang telah di komposkan dan penyajian data. Berdasarkan hasil analisis sesudah dan sebelum pengomposan, terjadi peningkatan kadar organik dan unsur hara makro dari limbah tambak udang yang telah dianalisis adalah C meningkat sebesar 352.2%, N meningkat sebesar 217.6%, Rasio C/N meningkat sebesar 41.6%, P2O5 meningkat sebesar 298%, dan K2O meningkat sebesar 615.3%. Berdasarkan hasil tersebut terjadi peningkatan yang sangat signifikan terhadap kandungan bahan organik dan unsur makro dari limbah tambak udang. Nilai unsur hara makro dari limbah tambak udang setelah dikomposkan telah memenuhi standar baku mutu pupuk organik padat namun kasar C-Organik masih belum memenuhi sehingga pada penelitian selanjutnya masih perlu dilakukan pengkajian untuk peningkatan kadar C-Organik.

Abstract

Coffee is one of the mainstay of plantation commodities that has a significant contribution to the Indonesian economy, namely as a source of export foreign exchange, a source of income for farmers, a producer of industrial raw materials and job creation. The high public interest in coffee drinks has made the existence of coffee plants a highly competitive plant, so that land suitability for coffee plants needs to be done. The method used in the coffee land suitability analysis is based on square root and ridha (the latest parametric approach). The results showed that the land suitability class using the square root method was N1 at all observation points of the soil profile. There are limiting factors for soil depth and pH of H2O (profiles 1, 2, 3, 4, 5 and 6) and salinity (profiles 1, 2 and 3) in Robusta coffee, while the land suitability class obtained using the Rabia method is the profile observation point. 2 and 3 are classified into N1 (not suitable at this time) with limiting factors for soil depth, pH H2O and salinity, while at the observation point profiles 1, 4, 5 and 6 on Robusta coffee are classified into S3 (according to marginal) with limiting factors. Soil physical characteristics (soil depth and pH H2O).
