Judul: Risiko Usaha Diversifikasi Melon Hidroponik pada PT Rejo Sari Bumi Unit Tapos di Kabupaten Bogor
Abstrak: Melons are part of the horticultural sector is one of the sectors that have an important role in the national economy because it has a great contribution in the formation of the gross domestic product (GDP) and national enough prospective subsector to be developed because it has a fairly high economic value. Research objectives include identifying sources of risk facing production PT Rejo Sari Bumi Unit Tapos in pursuit of a wide variety of melon, analyzing the relationship between diversification efforts of melon with effort the production risk and provide press strategy is best for the company in order to reduce the risk of production going on. This research using the method of variant analysis tools, standard deviation and coefficient of variation, as well as the expected return. Risk of production sources on this company, among others, changes in the climate or weather conditions, pests and diseases, Labor's fault. Based on risk analysis on a single commodity which organised the company obtained the highest risk found in musk melon while the lowest is at sunny sweet melon. Risk diversification analysis results produce a combination of golden, sunny and sweet musk melon is the most low-risk diversification.

Judul: Diversifikasi sayuran organik sebagai alternatif mengatasi risiko usaha pada The Pinewood Organic Farm di Kabupaten Bogor
Abstrak: Risk is the possibility of adversity or loss, and refers to uncertainty that matters. Consequently, risk management involves choosing among alternative to reduce the effect of risk. One of indicator to know the existence of production risk is the fluctuation in productivity of brokoli, tomato, bayam hijau, and carrot. This study analyzes the risk of commodity production in the four selected in the Pinewood Organic Farm with a diversified approach to analyze the risk of production of more than one commodity. Fluctuations in production will lead to revenues received also fluctuates, will be calculated risks and confectionary risk through the implementation of risk management strategies. Risk analysis is a comprehensive step in the risk assessment process. This assessment begins with the calculation of odds, the value of expected return, until the value of the risk. The analysis tools is the variance (the variance), standard deviation (standard deviation), and the coefficient of variation (coefficient of variation). Measures of deviation is also aided by another measure, namely the calculation of the odds and expected return. The results of the risk analysis calculations show that the specialization of business spinach organic green vegetables have the highest risk level of the four commodities. Based on the comparison of the risk on the four organic vegetables broccoli, tomatoes, green spinach, and carrots are done Pinewood Organic Farm concluded that diversification can reduce risk. However, by diversifying no means eliminate the risk or create a risk to zero. Diversified production activities in the Pinewood Organic Farm has been effectively implemented by the company in an effort to deal with the risk. The strategy needs to be done by the company is to improve the management of the company, to cooperate or partner with other farmers and suppliers of organic vegetables.

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
