Abstract

Research has been carried out on the preparation of active natural zeolite impregnated with nickel followed by activity testing through the hydrocracking catalytic reaction of n-Hexadecane. Active natural zeolite was obtained from PT Prima Zeolita Yogyakarta. The nickel concentration in the zeolite sample was carried out by ion exchange method with [Ni(NH3)6]2+ precursor solution with a concentration of 0.06M. The nickel content of the catalyst was determined by Atomic Absorption Spectrophotometer (AAS). The hydrocracking reaction used a fixed bed reactor system. Ratio of feed (n-Hexadecane) : catalyst = 3 : 1 (in gram). Catalysis study also carried out at various temperatures, from 315oC - 450oC at  certain nickel content.  The results of the catalytic reaction at each temperature after passing through the cooling system there was a liquid fraction that had been successfully accommodated then weighed and determined the percent of conversion. Furthermore, for the determination of Ea and the order of the reaction using linear regression calculations. The results showed that the catalytic reaction using an active natural Ni-Zeolite catalyst in the n-Hexadecane hydrocracking process resulted in different conversion results depending on the temperature of the catalytic reaction. The largest conversion was obtained at a temperature of 450oC, which was 35.18%. The reaction order was the first-order reaction (n=1). Meanwhile, the activation energy or activation energy (Ea) of the catalytic reaction in the n-Hexadecane hydrocracking process using a natural Ni-Natural zeolite catalyst with a nickel content of 2.0% (w/w) was 127.071 kJmol-1.

Abstract

Industry of tofu and tempe continues to grow in the city of Jayapura. In the Kali Acai area there are at least four tofu and tempe processing plants. In its processing, the industry also produces by by side products in the form of solid and liquid waste. The lack of knowledge and the high cost of liquid waste processing equipment make the factory managers generally immediately dispose of the liquid waste to Kali Acai without processing it first. This can cause the waters of Kali Acai and the surrounding environment to become contaminated. To overcome this problem, socialization and training for managers and employees of the tofu and tempe factory were conducted at Kali Acai times, especially the Ojolali tofu tempe industry about processing liquid waste in a simple way by utilizing coconut shells so that disposed liquid waste is safer and environmentally friendly. The stages of activities carried out included: location surveys and partner selection, preparation of tools and materials, implementation of activities, evaluation and reporting. The implementation of the activity consisted of delivering material, making activated charcoal and processing wastewater using activated charcoal for. Activated charcoal is made from coconut shell with a closed system while the active charcoal application for processing wastewater uses an adsorption technique. The evaluation was carried out through questionnaires for the participants. The results of the activity showed that activated charcoal was able to adsorb color and acid from liquid waste. This is indicated by the change in color from cloudy white to be rather clear and able to increase pH from 5,04 to 7,45 so that it is safer for the environment. In general, the implementation of service activities went smoothly and successfully which was demonstrated through the enthusiasm of the participants and the results of the questionnaire analysis which was filled out by the participants. Keywords: activated charcoal, coconut shell, liquid waste treatment, tofu and tempe waste

Abstract

Sago is a plant that has high nutritional value if it is processed according to production standards. Sago contains the Glycemic Index so it is very good for health, especially for diabetics. The process of making sago snack production in the form of training conducted in Yabansai Village, Heram District, Jayapura City. The method used was the participatory observation method of the object where the lecturer team implementing the activities and the training participants observe and were directly involved (face to face) in each step of their work. In addition, interviews were conducted with community service supervisors with target fields who were PKK mothers who had spare time and had not yet been used to produce something of added value to their family's economy. The activity began with a lecture related to the health benefits of sago as well as a lecture on the implementation instructions for the process of making sago snacks from the preparation of ingredients to the mixing and frying process of snack ingredients and ending with packaging. The end result of this activity provides benefits for activity participants to know and understand that the sago material consumed can be beneficial for health. Participants were also motivated to make sago snack businesses both individually and in partnership to open jobs, especially for those who have spare time and have been wasted so far. Participants understood that if a business wants to grow, it must have a permit from BPOM and a halal certificate from MUI. The important thing that impacts at least two things, 1) preservation of the source of sago material (sago tree) as a typical plant that is only found in certain areas.2) the use of sago raw materials to become a snack product with high economic value and in turn it can create jobs for the general public. Keywords: Sago; health; snacks; participants; motivated; business unit

Abstract

The use of formalin and borax as food preservatives is prohibited by the government, because this material is toxic (poison).However, some survey results indicate that several types of food ingredients in traditional markets and other food traders still contain formalin and borax. Therefore, it is necessary to introduce to the general public  how to identify formalin and borax use simple materials and tools. Qualitative test of formalin content in food was used fehling A and fehling B solution. While the qualitative test of borax content was used in turmeric which was prepared in the form of tumeric paper. Activities between speakers and trainees were held face-to-face and the practice of identifying food ingredients containing both formalin and borax were carried out directly in the laboratory. From the results of the activities that had been carried out, it can be concluded that although the ingredients for identification of formalin and borax in food ingredients obtained from simple ingredients, cheap and easy to obtain such as fehling A and fehling B and turmeric in the form of tumeric paper, but they can identify food ingredients contains formalin and borax. Fehling A and Fehling B solutions can identify qualitatively with significant results between that contain  and  not  contain formalin. Similarly, tumeric paper can identify qualitatively with significant results between that contain and not contain borax in food ingredients. Participants were very motivated to apply the results of this activity to the community where they live especially after seeing the results of qualitative tests using fish purchased at the Hamadi traditional market during this service. Qualitative test results using fehling A and B solutions identified red snapper purchased at the traditional Hamadi market using preservatives from formalin.Keywords: Formalin, Borax, Preservatives, Fehling A, Fehling B, Turmeric
