Soil erosion sensitivity of rubber plant, oil palm, and teak in Ogan Komering Ilir District

Soil erodibility was the ease with which soil erodes. The study aimed to determine the value of soil erodibility on rubber, oil palm, and teak land at PT Waimusi agroindah. The method used was a very detailed survey, assisted by digital maps. Soil samples were taken based on the study area. Soil samples were taken at 0–30 cm deep and topsoil for soil permeability analysis as well as the completeness of the tools and materials needed. The calculation of the value of soil erodibility on rubber, oil palm, and teak land has moderate criteria. The equation of these criteria in quantitative numbers for oil palm land has a value of 0.18, which was higher than rubber land at 0.15 and teak land at 0.13. While on forest land, the soil erodibility value was 0.04, so it falls into very low criteria. The conclusion of this research was that rubber, oil palm, and teak land obtained soil erosion sensitivity values with moderate criteria, and the results of soil erosion sensitivity values on forest land were classified as very low. This research was one of a series of several factors used to determine the potential for land erosion. Further research needs to be done so that the potential for erosion could be determined from all the factors that affect the potential for erosion.

Prediksi Jumlah Produksi Kelapa Sawit di Indonesia Menggunakan Algoritma Backpropagation

Indonesia is a country that has advantages in the agricultural sector which has the largest plantation and agricultural areas in ASEAN, one of which is oil palm plantations. Indonesia is one of the largest crude palm oil (CPO) business players in the world. More and more palm oil mills and oil palm land are being converted to oil palm cultivation, because oil palm plantations are more beneficial for farmers and palm oil processors. Palm oil plantations are still trying in several ways to maintain stable market demand, one of which is by increasing palm oil production, because palm oil is the main source of other product derivatives. Palm oil production fluctuates every month, but the ups and downs are caused by many factors, namely climate, rainfall, soil fertility, selling prices, and others. Reduced production has a direct impact on the income of farmers and workers in the sector, which in turn can cause economic instability. Actions are needed to ensure the continuity of this industry, one of which is by making predictions. One prediction technique is the Backpropagation artificial neural network. The prediction model can provide very accurate estimates of palm oil production at the provincial level. By analyzing historical data, this research can identify patterns that can help predict future palm oil production. The urgency lies in the strategic role of palm oil in the Indonesian economy.

Another objective is to determine the highest SDGs that contribute to the achievement of SDGs by examining 13 SDGs out of 17 SDGs analyzed using Principal Component Analysis (PCA) to estimate composite SDGs index. The survey was conducted in 7 provinces in Indonesia which are oil palm centers in Indonesia. Data was obtained from interviews with 3060 smallholder oil palm farmers divided into 3 strata based on the area of oil palm land owned. The results showed that the SDG composite index of smallholders reached 77.57 %, which informed that smallholder oil palm had reached 77.57 % of the 2030 SDGS target. This achievement is greater than the national achievement which reached 70.16 %. Of the 13 SDGs analyzed, SDG17 achieved the weakest followed by SDG5. While the highest achievement was obtained by SDG1 which was followed by SDG6 and SDG8. In the future, more comprehensive cross-sectoral research related to the achievement of SDGs, especially related to the impact of government policy interventions on the achievement of SDGs.

Lead and cadmium content in soil, oil palm fiber, and palm kernel in the oil palm plantation with mulch application

Solid waste in palm oil mills is waste that has the potential to have a negative impact on the environment if not used properly. One of the solid wastes from palm oil mills is empty fruit bunche (EFB) which can be used as mulch on oil palm land. The mulch and inorganic fertilizer used can contain heavy metals, such as Pb and Cd. This study was aimed to assess the heavy metal content of Pb and Cd in the soil, fibers and kernels of oil palm fruit. This study evaluated the Pb and Cd content in the soil at depths of 0 – 20 cm and 20 – 40 cm, palm fiber and palm kernel. The results showed of the study showed that the Pb and Cd content of soil on land applied with inorganic fertilizer was greater than the Pb and Cd content of soil on land applied with mulch, where on land applied with mulch the level of Pb contamination was in the very slightly contaminated category, while Cd was in the quite polluted category, and inorganic fertilizer land is heavily polluted. On land where mulch was applied, the Pb and Cd content of fiber and kernel was smaller than the Pb and Cd content of fiber and kernel on land where inorganic fertilizer was applied.

Analisis Kendala Program Peremajaan Sawit Rakyat (PSR) terhadap Potensi Pertumbuhan Ekonomi Petani Sawit Rakyat.

This study aims to analyze the effect of the community oil palm replanting program on the economic growth of community oil palm farmers in Batu Bara Regency. This research uses quantitative methods with multiple linear regression analysis techniques. Primary data was obtained from 75 respondents of smallholder oil palm farmers in Batu Bara District. The results showed that administration and human resources have a positive and significant influence on the economic growth of smallholders. Meanwhile, oil palm land, facilities and infrastructure, and sustainability have no influence on the economic growth of smallholders. This study implies that it is important to increase training and technical support for assistants and smallholders. The government needs to provide financing and incentives to encourage farmers' participation in the smallholder oil palm replanting program. A holistic economic growth strategy is needed, such as diversification of oil palm products, improvement of the value chain, and integration with other sectors. It is necessary to build strong cooperation with relevant stakeholders to improve program implementation and maximize economic benefits for smallholders.

Karakteristik Kimia Tanah pada Areal Kelapa Sawit dan Nilai Konservasi Tinggi (NKT) di Kabupaten Tapin, Provinsi Kalimantan Selatan

In the practice of oil palm plantation management, land clearing and cultivation using heavy equipment will change soil conditions from anaerobic to aerobic. This condition will cause sulfide compounds contained in the soil, or commonly referred to as pyrite (FeS2) to undergo an oxidation process that can cause the formation of sulfuric acid compounds (H2SO4) which when dissociated will release H+ ions in the soil solution, thus increasing soil acidity. In addition, improved drainage will also lead to a high likelihood of plant nutrients being leached from the soil. On the other hand, the HCV areas will be left unmanaged by maintaining the original vegetation adjacent to the oil palm plantations. So there are two different land management systems between oil palm land and HCV areas which in theory will have different land characteristics, one of which can be seen from differences in soil chemical characteristics. The purpose of this study was to determine the differences in the characteristics of several soil chemical properties including pH, C-organic, Al-dd and P-available in oil palm land and HCV areas. This research is a field research using survey method. Sampling in the field was carried out by purposive sampling at PT Kharisma Inti Usaha, Tapin Regency, South Kalimantan Province. Soil samples used in this study were soil samples at a depth of 0-30 cm and 30-60 cm on oil palm land and HCV areas where each land was taken as many as 10 sampling points, so that the total sample points amounted to 40 sampling points. The results showed that the characteristics of soil acidity (pH), carbon (C-organic), aluminum (Al-dd) and phosphorus (P-available) on oil palm land were lower than HCV areas in PT Kharisma Inti Usaha Tapin Regency.

Potential and role of bird diversity in various oil palm land cover of PT Selatan Agro Makmur Lestari, South Sumatra

The change in the development paradigm to a “green economy” requires the management of oil palm plantations (as one of the national strategic industries) to make more use of biodiversity in increasing its productivity. In addition to reducing production costs (the use of chemical fertilizers, chemical pest and weed control), optimizing the use of biodiversity in oil palm agrosystems will be able to realize the management of oil palm plantations in a sustainable and environmentally sound manner. This study aims to identify the potential for species diversity and the role of birds in oil palm plantation agrosystems. Data collection on the potential for species diversity was carried out on six types of oil palm plantation land cover at PT Selatan Agro Makmur Lestari, South Sumatra with the transect line method along 1 km with a width of 50 meters. As for the role of various types of birds in the ecosystem, a literature review is carried out. The highest number of species and individuals was found in shrubs as many as 19 species and 69 individuals. On the other hand, the lowest number of species and individuals was found in smallholder oil palm plantations-II with 6 species and 16 individuals. In terms of the number of individuals, cave swiftlet (Collocalia linchi) was the largest species with 58 individuals, while cerulean kingfisher (Alcedo coerulescens), pink-necked green pigeon (Treron vernans), and white-headed munia (Lonchura maja) were the species with the fewest individual encounters. (only 1 individual). Based on the literature review, the types of birds found at the research site have four ecological roles. There are insect pest controller, seed dispersers, predator, and weed controller. Further research is needed to examine more deeply the role (quantitative ecology) of each bird species in oil palm agrosystems.

Differences in Rubber Plant Production in Swamp and Land in North Sumatra

This study aims to analyze the differences in the production of rubber planting in swamp land and land in North Sumatra. Rubber plants are one of the mainstay commodities in North Sumatra Province along with oil palm plantations. It's just that lately many rubber farmers are converting rubber land to oil palm land. This causes the production and price of rubber commodities to fluctuate. One way to prevent this is to plant rubber in swampy soil. This research uses descriptive qualitative research. Collecting data by observation, interviews, document analysis, literature study, especially using previous research data. The results of this study indicate that there has been a decline in rubber production during the last ten years due to the conversion of rubber land to oil palm land whose main consideration is economic motives, both the increasing price of palm oil and decreasing rubber prices. It's just that, at the same time, rubber plantations have started in swamps that were previously untouched. However, the results are not quite satisfactory compared to rubber plants in dry land. Further research is needed on the factors that influence it and solutions to these problems

The termites were sampled using the transect method. Data were analyzed using ANOVA and LSD test at 5% level of significance. Six termites genera were found acroos five typologies of oilpalm (old oilpalm, young oil palm, shrub/grass, cassava and swamp land), i.e. Globitermes, Odontetermes, Macrotermes, Hypotermes, Schedorhinotermes and Bulbitermes. However, it was estimated that three more other genera would be found if the number of samples (typology) was increase (extrapolated). There were differences in the diversity of termites accros oilpalm typologies (five genera in old oilpalam, four genera in young oilpalm, two genera in cassava, and only one genus in shrub/grass. The relative abundanceof termites was highest in the old oilpalm (18 counts), followed by young oilpalm (14 counts), cassava (5 counts) and shrub/grass (3 counts). The ranking of termites relative abundance had an exponential pattern, with Macrotermes and Bulbitermes being the most and the least abundance genera, respectively. Environmental factor that effect the richness of the termite genus are humidity, wood volume and litter weightand environmental factor that effect distribution and frequency of termite findings are influenced by frequency of termite findings are influenced by the level of canopy cover, humidity, wood volume, litter weight and litter organic C.

Workload analysis on the operation of a type II pivot trailer on a hand tractor using tire wheels in oil palm plantations

In general, several oil palm fields in Indonesia have different slopes, so that the path on the land is difficult for farmers to pass in the process of transporting palm fresh fruit bunches (FFB). The slope of the land and the difficult path causes a lot of workload incurred by farmers. The pivot II type trailer which is the development of the pivot type trailer is expected to reduce the workload of farmers in transporting the oil palm FFB. The purpose of the study was to analyze the operator’s workload on the operation of a pivot II type trailer using a hand tractor using tires as a drive in oil palm plantations. Analysis of workload when operating a pivot II trailer using the heart rate method on three subjects with various variations in trajectories, turns and trailer loads. The results of this study indicate that the qualitative workload level of operators O1, O2, and O3 in operating a pivot type II trailer on oil palm land, both on flat land, sloping land 10° and sloping land 30° has a workload level of “Light” category. Meanwhile, the operators’ quantitative total energy cost (TEC)’ workload levels for slope 0°, 10°, and 30°, respectively, are 1.31, 1.48, and 1.67 kcal/kg.hour. The operator’s workload level on the pivot II type trailer is better when compared to the initial pivot type trailer before modification.
