(The Influence of Extraction Temperature Treatment on Cocoa Butter Quality Characteristics) Lukman Junaidi; Agus Sudibyo; Tiurlan F.Hutajulu; Dede Abdurahman

Research on the influence of Extraction Temperature Treatment on Cocoa Butter Quality Characteristics gas been conducted. The study was focused on the effect of treatment of the extraction temperature range when conducted hydraulic pressing on cocoa nibs. The variation of temperature range was chosen at: 40'-50'C: 50'-60'C: 60'-70'C: 70'-80'C: 80'-90'C. The research showed that treatment of extraction temperature level give an influence on the cocoa butter quality characteristics e.g: moisture content, FFA, sapnification value, iodine number and refrective index. The results showed that moisture content of cocoa butter extracted decrease with increasing of ectraction temperature, while FFA, saponification value, iodine number and refractive index increase with increasing of extraction temperature.The treatment of extraction temperature level also give influence on the proportion of fatty acid type (saturated fatty acid and unsaturated fatty acid) on coca butter. The proportion of total unsaturated fatty acids tend to decrease with increasing of extraction temperature. On the other hand the proportion of total saturated fatty acids and yield of extraction tend to increase with increasing of eextraction temperature.

(Techno-economic Analysis of Small Scale Poultry Feed Industry) Lukman Junaidi; Rizal Alamsyah; Mochamad Noerdin NK; Tiurlan F. Hutajulu

Techno-economic analysis was conducted to evaluated to evaluate the financial viability of small-scale pourly feed industry. the analysis was based on three scale of capacity. that is: 4 tones, 2 tones, and 300 kg feed per day. the result of analysis shown that the viability of the pourtry feed industry was not sensitive to changes in the investment cost. however, the viability of the poultry feed industry was very sensitive to changes in the raw materials cost and feed price.

(Antioxidants : Mechanism of Action and Its Function in Human Body) Hendra Wijaya; Lukman Junaidi

Antioxidant could be defined by several means. Antioxidant is a substance that could postpone and delay oxidation of molecule substrate in human body ,i.e ; protein ,carboydtrate,lipid and DNA, by oxidant. antioxidant that works in the human body's biological system is called a biological antioxidant Biological antioxidants can be grouped into :1) enzymatic antioxidants (endogenous) ,2) non-enzymatic antioxidants (endogenaous) and, 3) antioxidants from food (exogenous0.Enzymatic antioxidants (endogenous) include superoxide dismutase ,catalase ,glutathione peroxidase, glutaredoksin, tioredoksin, peroksiredoksin ,and coenzyme q10.non-enzymatic antioxidants (ENDOGENOUS) are carotenoids,vitamin E and vitamin C those antioxidants are able to work in hydrophobic and hydrophilic cellular environment so as to from a strong network of cooperation in preventing the occurrence of oxidative damage .some of the functions of antioxidants in the human body that can be expressed are ; preventive defense the human body against oxidants ,strong defense system against free redicals ,prevent the occurrence atherosclerosis in blood vessels,regulation of metabolism such as disabling lipoksigenase.

(The Effectiveness of Bamboo Charcoal as a Cigarette Smoke Filter) Lukman Junaidi; Hendra Wijaya

Research on effectiveness effectiveness of using bamboo charcoal for cigarette smoke filter has been conducted .the aim of research was to investigate the characteristics of bamboo charcoal as a cigarette smoke filter .the results show the type of bambo charcoal andong and betung as well as particle size give no significance influence on benzene and chloroform adsorption ,while in contrarily give significance influence on significance influence on benzene and chloroform adsorption,while in contrarily give significance influence on 0idium adsorption .usingthe cigarette filter added with bamboo charcoal andong and betung could increase 90% tar adsorption in cigarette smoke compare to tar adsorption by cigarette filter without bamboo charcoal added .while bamboo charoal filter andong and betung could increase nicotine adsorption in cigarette smoke only 45% and 19% respectively compare to tar adsorption by cigarette filter without bamboo charcoal added. The size of mesh of bamboo charcoal filter andong and betung give same level of influence on tar and nicotine adsorption.the lower the size of mesh the higher the effectiveness on tar and nicotine adsorption.

(The Study on The thermal Energy Consumption and Effisiency in Coconut Oil Processing Using HOID Technology) Lukman Junaidi; A S Tariq; Yang Yang Setiawan; Dadang Supriatna

The study on the thermal energy consumption and efficiency in coconut oil processing using HOID technology was conducted to evaluate the performance of the thermal energy efficient fumace. the preliminary comsubtion experimental conducted to examine the thermal capacity of the system, indicated that the system could be used to fry minimum of 2 tons coconut meat per 8 hours operation. The frying capacity of the furnace was influenced significanrtly by the ration of the fresh coconut meat to coconut oil and the amount of coconut oil that should be replaced. The higher the ration will result in the higher of the frying rate. The result of experiment showed that the maximum thermal efficiency of the fumace was around 70% this maximum efficiency could be achieved if the loss of the thermal energy from the system could be made minimally, espencially loss due to the sensible heat in the dry flue gas and loss due to the incomplete combustion of fuel resulting in carbon monoxide in the flue gas. The average thermal efficiency of the system was 54%.
