Abstract

Biocomposite is an innovation of renewable material in engineering made from the bark fiber of waru (Hibiscus tiliaceus, the bark is environmentally friendly and has the potential to be developed. The purpose of this study is to modify biocomposite by adding methacryloxypropyltrimethoxysilane-coupling agent on waru bark fiber (Hibiscus tiliaceus) as an effort to improve tensile properties. Waru bast fibers, as reinforcement, were prepared by alkali procces using 6% NaOH solution for 120 minutes and then added 0.75% coupling agent and  ordered using continous fibers with 0°/0°, 0°/90° and 45°/45° orientation. After that, the Biocomposites  were formed with a polyester matrix using Vacuum Pressure Resin Infusion (VAPRI) method. The results of SEM tested showed the quality improvement of the bonds bringing significant impact on the tensile properties of the waru bark biocomposite. On the continous fiber 0°/90° orientated  showed that the highest strength was 401.368 MPa, while biocomposites with 45°/45° orientation has lowest tensile strength of 65.243 MPa

Abstract

Gerandong currently is illegal vehicles circulating in the community, namely motor vehicles used for mobile rice mill facility by people who operate on the highway. The problem faced is the need for cheap transport of agricultural field of the community, while there are low-tech impact on the feasibility of operating licenses as a vehicle that runs on the highway, security levels, and pollution. Based on these problems Gerandong vehicle license ban needs to be solved in a comprehensive and integrated from upstream to downstream, in order to provide economic benefits, the development of science and technology for society, and safe for the environment. Gerandong management regulations are needed to ensure legal certainty, clarity of responsibility and authority of the government, and the role of society and the business world, so gerandong as an alternative vehicle for agriculture are proportional to run effectively and efficiently.

Abstract

Law as a social construction instrument should be able to improvesocial system and face the challenge of this changing era. However,what happens in our society nowadays shows that people tend to haveless trust to law. It is proven by opponents of inadequate quality of lawas the agent of social construction and the substantive justice.Additionally, the anxiety of legitimating crisis occurs. Law as a media ofsocial construction, which is aiming at creating fair and prosperoussociety, seems problematic to be accepted. In this case, realizing thecause of people’s problems in interpreting and accepting the purposeof law as a social construction instrument becomes the importantmatters. The level of people’s education leads to the low law awareness.The education systems, the pattern of regulations socialization, thelimitation of public information access may lead to low recognitiontoward law. Regarding the problems abovementioned, educationbecomes one of alternative solution. It is expected that the higherpeople’s law awareness, the lower people’s opportunity to break thelaw. Thus, public education may promote the implementation ofconstruction of modern society.

Abstract

The scarcity of fuel oil in the future needs to be anticipated by preparing alternative energy. One of the alternative energy sources developed is Jatropha. However, the development of Jatropha should use marginal land as a cultivation area, like a dry land, because the food crops and horticulture use productive land for cultivation. Furthermore, Jatropha development through breeding is an effort to obtain superior varieties as biodiesel producers. This study aimed to determine the best phenotype characteristics of hybrid Jatropha plants as superior candidate trees. This research applied a descriptive qualitative method to determine the characteristics of Jatropha crossing results. The Jatropha characterization was conducted at the experimental garden of Kedung Pengaron Village, Kejayan Sub-district, Pasuruan Regency. The experimental garden was included dry land for Jatropha cultivation. The result showed ten selected genotypes of hybrid Jatropha were found, including 05.01.01, 05.01.02, 05.02.02, 05.02.09, 05.03.17, 05.03.16, 05.04.16, 05.04.15, 06.01.02, 06.01.15. These were based on the two-phase observations, consisting of vegetative and generative observations. The plants’ morphological characters were observed, comprising the stems, leaves, flowers, fruits and seeds. In the vegetative phase, diversity was found in the number of leaves, leaf length and age of flowering, while in the qualitative phase, the shoot colors were more diverse. Moreover, less variations were figured out in the color character of the petiole and the number of shoots. These ten genotypes of hybrid Jatropha are the best genotypes that are resistant to drought with selected agronomic characters.
