Abstract

The region in Indonesia is indicated to have many critical lands. Critical lands are lands that have experienced degradation so that the land cannot function properly. In other words, efforts to obtain benefits from the level of productivity that should not be comparable to the results of production. Therefore, efforts must be made to improve the land so that its productivity can recover. In the Curug sub-district, Bogor City, there are critical lands. This critical land is caused by steep land topology and high rainfall. One of the critical land areas is the Curug River watershed. The slope of the land on the side of the river exceeds a slope of 45ยบ. High rainfall causes the land to experience cracks accompanied by subsidence of the land surface. One of the handling efforts that can be carried out on an ongoing basis is integrated reforestation. Based on these problems, the aim of this community service (PKM) is to provide education regarding the dangers of critical land and cultivating critical land with durian seeds. This activity was carried out by a team consisting of source persons, lecturers and students from the Faculty of Earth and Energy Technology, Trisakti University. The PKM activity was attended by the Head of RW 13 and the Head of RT 3 in Curug Village and their staff. Apart from that, the PKM was attended by the men and women of RT 3 residents who actively participated in counseling activities and planting durian seeds along the areas along the river and other areas.

Abstract

One phenomenon that can occur when a polymer solution is injected into an oil reservoir is adsorption. Adsorption occurs due to interactions between polymer molecules and the reservoir pore surface. Adsorption causes some polymer molecules to be removed from solution. So, this process results in a reduction in the polymer concentration in the solution. In this study, an artificial neural network (ANN) model is used to estimate the adsorption of shrimp chitosan polymer on the surface of 40 mesh and 60 mesh sand grains. The ANN model can estimate adsorption more accurately than previous models. This is because previous models only predicted certain adsorption patterns, while the ANN model is able to predict adsorption with complex relationships. The comparison of the mean absolute relative errors (MAREs) of the ANN, Langmuir, Freundlich, Henry, and Harkins-Jura models is 5.7%, 15.9%, 14.6%, 15.2%, and 14.5%, respectively.

Abstract

Porang tubers contain glucomannan which is used in various industries. Porang is a biopolymer that has the potential to be applied in polymer flooding in oil reservoirs. In this research, a combination of porang and Xanthan gum was used for displacing oil in the laboratory. The samples analyzed varied with polymer concentrations of 2000, 4000, and 6000 ppm respectively for porang solution, Xanthan gum, and a mixture of porang and Xanthan gum. The salinity of the formation water used in this research was 6000, 12000 and 18000 ppm. The experiment aimed to observe the characteristics and performance of porang and Xanthan gum including testing for compatibility, viscosity, adsorption and sandpack flooding. Based on the test results, all samples were compatible. The application of a mixture of porang and Xanthan gum provided lower adsorption compared to the application of only Xanthan gum. The highest reduction in adsorption value given was 3.545 mg/gr. The highest viscosity and additional recovery factor were given by a mixture of porang and Xanthan gum with a concentration of 6,000 ppm and a salinity of 18,000 ppm, namely 284.72 cP and 16.1%, respectively.
