Abstract

This article aims to describe a new paradigm of sustainable community service. The background is the phenomenon is that there is no mutualism symbiosis of various parties and the key actors of empowerment in fulfilling the needs, challenges, and implementation of the community, either directly or indirectly. The method used in this article is literature studies and from various experiences of the author in doing community service. To run and understand the new paradigm of community service, there are at least three models that can be used, namely triple helix, quadruple helix, and quintuple helix. The dynamics of community empowerment require innovations that support sustainable development. The quintuple helix model is relevant for viewing current and future conditions.

Abstract

Abstract A cooperation between higher education institution, industry and local government is important to overcome problems in rural poor areas through empowerment and financial support for various programmes to increase competencies and welfare of poor farmers. In this paper, an example of the cooperation is a development of Kawasan Ekonomi Masyarakat (KEM) Kelurahan Batu Bersurat and Kampung Bantalan Propinsi Riau in 2014-2016 through Corporate Social Responsibility and Small Medium Enterpreneur and Partnership Program (CSR & SMEPP) PT Pertamina with Forum Layanan Iptek untuk Masyarakat (FLipMAS) Batobo Wilayah Riau-Kepulauan Riau and local governments. The empowerment program that has been carried out was a development of marginal lands at both KEM for agriculture, freshwater fishery and animal husbandry, such as chili cultivation, patin fish cultivation and Balinese cow husbandry. A mentoring strategy by FLipMAS BATOBO at both KEM generally comprises principles of empowering society, group, networking, and sustainability. The results of effective mentoring showed an increase of the farmer’s income to more than 80% from the initial condition, and a change of farmers character that is willing to help poor people and orphans in their areas. This could indicate an achievement of the cooperation between the institution, industry and government in empowering society in rural poor areas.

Abstract

Duri steam flood is the largest hot steam injection project in Indonesia, facing challenges in preventing production declines. Objective project is showed decrease in production due to crustal deposition (scale). The Stiff and Davis method shows a Stability Index of 1.43, with a tendency for scale formation, especially CaCO3, in accordance with the Ryznar method. Increasing the production of x, yz layer wells in the Duri field, designing acidification stimulation with a pumping pressure of 400 psi, an injection rate of 2 bbl/minute and an acid volume of 600 gallons, after that comparing the performance of hydrochloric acid and carboxylic acid. Analysis showed that hydrochloric stimulation resulted in a significant increase in production of 115 BFPD / 8 BOPD (42% increase), while carboxylate stimulation showed a slower increase of 40 BFPD / 3 BOPD (24% increase). An economic evaluation shows chloride acidification produces an annual NPV gain of $48,002, compared to carboxylate acidification with an annual NPV gain of $22,554. Thus, chloride acidification proved to be economically profitable for the x, yz layers in the Duri field. This study highlights optimal acid stimulation strategies to mitigate scale-related production challenges in steam flood projects.

Abstract

Nitrocellulose is an important compound in the chemical industry, which has various crucial applications, such as the main ingredient for making quality paint, ink, and coating formulations in the printing process, as well as a propellant (explosive). Nitrocellulose as a raw propellant material is currently very popular. In this research, pineapple leaf waste has been processed as a raw material for making nitrocellulose through a nitration process. The research aims to determine the effect of the nitration process's length and the nitrating acid's composition on nitrocellulose's nitrogen content. Before the nitration process, an initial process is carried out, namely pre-treatment of pineapple fiber to obtain fiber with a cellulose purity of >92%. In the nitration process, the ratio of titrating acid (H₂SO₄:HNO₃) used is 1:3, 1:2, 2:1, 7:3, and 3:1 with a nitration time of 30, 60, 90, and 120 minutes. The results obtained in this research were that the pre-treatment process was able to increase the purity of cellulose in pineapple fiber by up to 93%. Then the 2:1 titrating acid formulation (H₂SO₄:HNO₃) is the best acid ratio formulation. Meanwhile, the optimum time for nitration is 60 minutes, with a nitrogen content in nitrocellulose of 12.73%. Fourier Transform Infrared (FTIR) analysis shows that there has been an exchange of hydroxyl groups in nitrocellulose with nitro groups, which is indicated by the presence of a peak indicating the nitro group. Apart from that, the burning test also showed that nitrocellulose can be burned faster than cellulose
