Implementasi Penilaian Daur Hidup Produk Susu Sapi Segar (Studi Kasus Koperasi Peternak MJM)

The growth of the milk industry in Indonesia is increasing every year. This is due to population growth, Indonesian income increasing, and their awareness of consuming milk benefit. Milk production in Indonesia comes from small and medium-term farmers, requiring Koperasi to improve the quality of dairy products in Indonesia. Koperasi Mitra Jaya Mandiri (MJM) consists of dozens of small local farm which all activities are still done manually. Activities of Koperasi MJM, farmers and milk transportation have an impact on the environment. The objective of this research is identify inputs, outputs and environmental impacts in the production of 1 kg of fresh milk (case study of Koperasi MJM). The methods used are life cycle assessment (LCA) with three impact categories: global warming (GWP), eutrophication potential (EP) and acidification potential (AP). The boundary of LCA study is "cradle to gate", which include: feed production, dairy farming activities, transportation of milk to Koperasi, cooling of milk in Koperasi and transportation of milk to factory. Based on LCA results, the environmental impact of GWP, EP and AP 1 kg of Koperasi MJM fresh milk equals 3.45 kg CO2 eq, 0.018 kg PO43- and 0.0208 kg SO2 eq. The stage of dairy farming activities has the highest environmental impact in these three categories. Environmental impact reduction can be done by processing feces of cow, or choosing feed additive that more environmentally friendly.

PENGEMBANGAN MODEL BAHAN AJAR BERORIENTASI MICRO DIDACTIC YANG MEMUAT PEMAHAMAN KONSEP PERTIDAKSAMAAN LINEAR DI SEKOLAH MENENGAH PERTAMA

AbstractThe concept of inequality is a prerequisite for solving problems in other mathematical contextssuch as in linear programming, expressing the domain of functions, compiling trigonometricequations, and also optimizing geometric analytic. However, the teaching materials for thistopic is very few and there are also some misconceptions of students in solving linearinequalities. One of the alternatives for this problem is to develop a teaching material modelwith a didactic micro-orientation which contains an understanding of the concept of linearinequality based on NCTM (National Council of Teachers of Mathematics).

Environmental Remediation Full-scale Implementation: Back to Simple Microbial Massive Culture Approaches

Using bioaugmentation and biostimulation approach for contaminated soil bioremediation were investigated andimplemented on field scale. We combine those approaches by culturing massively the petrophilic indigenousmicroorganisms from chronically contaminated soil enriched by mixed manure. Through these methods, bioremediationperformance revealed promising results in removing the petroleum hydrocarbons comparatively using metabolite byproduct such as biosurfactant, specific enzymes and other extra-cellular product which are considered as a difficult taskand will impact on cost increase

Crude Oil Biodegradation Potential using Acinetobacter baumannii CYA20 and Bacillus subtilis CYA27 from the Bekasi Coast, Indonesia

The pollution of coastal areas caused by oil spills is an environmental issue that needs further attention. Crude oil contains persistent organic pollutants (POPs) that are difficult to degrade. This study aimed to isolate bacterial strains capable of degrading crude oil from the Bekasi coast through bacterial isolate characterization and crude oil biodegradation tests using a crude oil-enriched microcosm model. Two strains with higher TPH degradation values were selected among the isolated bacteria, namely CYA20 and CYA27, which specifically showed values of 46% and 66%, respectively. These strains were tolerant to NaCl concentrations of up to 4% and 12%, respectively, and they were also tolerant to pH values ranging from 5 to 9 and temperatures between 10°C and 50°C.  Both strains were shown to utilize POPs, such as phenanthrene and fluorene, produce biosurfactants, and exhibited an emulsification activity in paraffin ranging from 0.373 to 0.533. Phylogenetic analyses identified these bacterial strains as Acinetobacter baumannii CYA20 and Bacillus subtilis CYA27, respectively. The results of this study indicate that these isolates could be developed as biodegradation agents for the bioremediation of crude oil-contaminated environments

Adaptation Selection of Plants for Utilization in Phytoremediation of Soil Contaminated by Crude Oil

The research on adaptation selection for utilization in phytoremediation of soil contaminated by crude oil using four type plants, such as Helianthus annuus, Paspalum conjugatum, Sorghum bicolor, and Tagetes erecta were conducted. The adaptability of four types of plants  on crude oil contaminated soil at total petroleum hydrocarbon (TPH) level at 0, 3, and 6% were observed and evaluated to their morphological and anatomical responses. Parameters observed were vegetative growth of plants including growth precentage, plant height, number of leaves, root length, root dry weight, shoot dry weight, root/shoot ratio, total dry weight, and stomatal density for 9 weeks cultivation in screen house. The results show that increasing in TPH level caused in significant reductions on morphological of four plants, such as percentage of plant growth, plant height, number of leaves, root length, root dry weight, shoot dry weight, and total dry weight. In contrast, the increasing in TPH level caused to increasing in root/shoot ratio. The four types of plants studied were effective to be used as plants for phytoremediation of petroleum contaminated soil. The plants of P. conjugatum and S. bicolor are recommended as phytoremediators for further studies

Anaerobic Decomposition Process Characteristics of Various Sizes of Garbage in a Lysimeter System

Garbage is produced daily in significant quantities especially in densely populated areas, creating serious environmental problems. On the other hand, the garbage has a high organic content and is a potential resource for producing renewable energy in the form of biogas. The implementation of an integrated approach to the environmental management gives hope to create a win-win solution to solve the strategic problem.  The research work aims to characterize the biodegradation process of garbage in a lysimeter system. The lysimeters were intended to simulate the real conditions of landfill. The experiments were performed using 5 lysimeters filled with various sizes of garbage, consisting of powder (A), 0.1 – 0.9 cm (B), 1.0– 1.9 cm (C), 2.0 – 2.9 cm (D) and original shape (E). Observations were conducted for duration of 150 days focusing on the alteration of the fed material and the products of the conversion process. The research results showed that the process of biodegradation is unique to each garbage size variation. In the beginning phase, the biogas was dominated by methane gas (CH4) in lysimeter A, while CO2 was predominant in the other lysimeters. The smaller size of the garbage the larger volume of biogas was produced. In opposite, the larger size garbage was biodegraded, the faster garbage volume reduction and the higher leachate production will be.
