The number of economic needs is one of the fundamental aspects to support the survival of every individual in an area.  If seen in general, the cost of building the building and residential community still use building materials and installation costs are relatively higher.  With the advancement of technology has found a lightweight brick that has better strength, lighter, faster installation and environmentally friendly, so many people began to switch to using lightweight bricks.  For now the price of lightweight brick is still expensive, but this deficiency is covered with the speed of mounting and light weight so overall lightweight brick usage on certain patterns is very profitable.  The use of cement on lightweight bricks leads to high production costs.  With the above problems we have a breakthrough to replace the cement by using zeozolites containing silica compounds that resemble one of the cement compounds.  In this research, cement replacement with Zeolite is 20%, 40% and 60%.  Before use Zeolite was first activated using Fly Ash ratio of 65% Zeolite: 35% Fly Ash and 50% Zeolite: 50% Fly Ash, also activated using Ca (OH) 2 ratio 65% Zeolite: 35% Ca (OH) 2  And 50% Zeolite: 50% Ca (OH) 2.  Thus, there are 15 compositions including the control composition, each composition will be made up of 10 specimens.  Hypothesis testing using two way anova, tested is the effect of cement change treatment with Zeolite and comparison of Zeolite composition with Fly Ash and Ca (OH) 2 to compressive strength, absorption and cost. Keywords: Zeolite, Cement, compressive strength, Cost

Since World War II, U.S. agriculture has reduced production costs by substituting petrochemicals for labor. Adverse impacts from chemical intensive agriculture include increased pest levels, groundwater and surface water contamination, soil erosion, and concerns about harmful levels of pesticide residues. Sustainable farming programs such as integrated crop management (ICM) and organic farming encourage farmers to use systems that reduce the adverse impacts of chemical agriculture. However, before farmers adopt an alternative system, they must determine that economic benefits from the alternative farming activities exceed the costs incurred. Unfortunately, relatively few studies have compared the cost of organic crop production with conventional production systems. Results of these studies are mixed. In some studies, organic systems are more profitable than conventional systems with organic price premiums, but are not economically viable without price premiums. In one long-term study, the organic system was more profitable than a conventional one if the cost of family labor was ignored, but less profitable if it was included. In some studies, net returns were higher for ICM than for conventional or organic systems, but in others, they were higher. Results also vary on a crop by crop basis.

PCBN-inserts have a high potential in the cutting of hardened steel, cast iron and super alloys due to their high hardness and heat resistance. Nevertheless they have a high purchase price, which lowers the economic benefits for the end user compared to other cutting materials. This is caused by the high production costs of the inserts. The grinding of PCBN-inserts causes a major proportion of these costs as a result of the high grinding wheel wear. The primary wear mechanism is grain breakout followed by clogging of the grinding layer. This study shows that the efficiency of the grinding process can be increased significantly by applying low cutting speeds and high feed rates. In this case, splintering of the grinding grain is the main wear mechanism.

ABSTRACT UD. Prima Bhakti is a food industry that is engaged in processing cassava into cassava chips which are located at Jalan Kemuning, Karangligar Village, West Telukjambe District, Karawang District, West Java. This factory experienced problems in the system of controlling high production costs which impacted on rising selling prices. The occurrence of production costs swelling due to the lack of good cost management. The costing used by the company is currently based on past cost data which is then made an estimated cost that will occur. From the above problems carried out a study of the design of the cost of production through the approach of Activity Based Costing (ABC). Activity Based Costing method is a method of calculating costs that imposes first costs on activities, then on products based on the use of activity by each product. Activity Based Costing System method identifies the activities carried out, tracing the costs to these activities and then using various cost drivers to trace costs, activities to cost objects. Key words: Cassava chips, cost of production, activity based costing ABSTRAK UD. Prima Bhakti merupakan industri makanan yang bergerak di bidang pengolahan singkong menjadi keripik singkong yang beralamat di Jalan Kemuning Desa Karangligar Kecamatan Telukjambe Barat Kabupaten Karawang Jawa Barat. Pabrik ini mengalami permasalahan pada sistem pengendalian biaya produksi yang tinggi yang berimbas pada naiknya harga jual. Terjadinya pembengkakan biaya produksi dikarenakan belum adanya manajemen biaya yang baik. Penetapan biaya yang dipakai perusahaan saat ini didasarkan pada data biaya masa lalu yang kemudian dibuat taksiran biaya yang akan terjadi. Dari permasalahan di atas dilakukan suatu penelitian mengenai rancangan harga pokok produksi melalui pendekatan Activity Based Costing (ABC). Metode Activity Based Costing adalah metode kalkulasi biaya yang membebankan biaya pertama-tama pada aktivitas, lalu pada produk berdasarkan penggunaan aktivitas oleh setiap produk. Metode Activity Based Costing System mengidentifikasikan aktivitas yang dilaksanakan, menelusuri biaya keaktivatas tersebut dan kemudian menggunakan berbagai pemicu biaya (cost drivers) untuk menelusuri biaya, aktivitas ke objek biaya.

ABSTRACT Isoprene is a valuable petrochemical used for a wide variety of consumer goods, such as adhesives and synthetic rubber. We were able to achieve a high yield of renewable isoprene by taking advantage of the naturally high-flux mevalonate lipid synthesis pathway in anaerobic methane-producing archaea (methanogens). Our study illustrates that by genetically manipulating Methanosarcina species methanogens, it is possible to create organisms that grow by producing the hemiterpene isoprene. Mass balance measurements show that engineered methanogens direct up to 4% of total carbon flux to isoprene, demonstrating that methanogens produce higher isoprene yields than engineered yeast, bacteria, or cyanobacteria, and from inexpensive feedstocks. Expression of isoprene synthase resulted in increased biomass and changes in gene expression that indicate that isoprene synthesis depletes membrane precursors and redirects electron flux, enabling isoprene to be a major metabolic product. Our results demonstrate that methanogens are a promising engineering chassis for renewable isoprene synthesis. IMPORTANCE A significant barrier to implementing renewable chemical technologies is high production costs relative to those for petroleum-derived products. Existing technologies using engineered organisms have difficulty competing with petroleum-derived chemicals due to the cost of feedstocks (such as glucose), product extraction, and purification. The hemiterpene monomer isoprene is one such chemical that cannot currently be produced using cost-competitive renewable biotechnologies. To reduce the cost of renewable isoprene, we have engineered methanogens to synthesize it from inexpensive feedstocks such as methane, methanol, acetate, and carbon dioxide. The “isoprenogen” strains we developed have potential to be used for industrial production of inexpensive renewable isoprene.

Due to the lack of high standardization and specialization, the production scale of modular substation is difficult to meet the established requirements. Compared with traditional substation construction, there are still practical problems such as high production costs. Therefore, it is still difficult to promote modular substation. Considering the life cycle of modular substation project, Cost Breakdown Structure (CBS) and Engineering Breakdown Structure (EBS) of the modular substation were defined through literature reading and data analysis. Then use the life cycle cost mapping model to further determine the mapping relationship between CBS and EBS. Finally, the connotation and goal of the life cycle cost optimization of modular substation were proposed, which can effectively promote the cost management of modular substation projects and optimization.
