Natrium benzoat, kalium sorbat dan natrium sakarin merupakan bahan pengawet dan pemanis yang digunakan dalam makanan dan minuman. Telah dilakukan penentuan kadar natrium benzoat, kalium sorbat dan natrium sakarin (BENSORSAK) dalam saos sambal produksi industri rumah tangga dengan menggunakan Kromatografi Cair Kinerja Tinggi (KCKT). Kadar natrium benzoat untuk sampel A 2.577,33 mg/kg, sampel B 858,25 mg/kg, sampel C 1.905,88 mg/kg dan sampel D 2.295,83 mg/kg. Kadar natrium benzoat pada Sampel A, C dan D melebihi batas maksimal Menteri Kesehatan RI No 722 / IX / 88, yaitu 1 g/kg untuk asam benzoat atau garamnya. Kadar natrium sakarin yang terdapat pada sampel B 129,98 mg/kg dan sampel C 133,01 mg/kg masih dalam batas yang ditetapkan PerMenkes RI yaitu 0,5 g/kg. Sedangkan kalium sorbat tidak ditemukan dalam sampel saos sambal.

ABSTRAKThe objective of this research is to analize the effect of temperature on the output power of photovoltaic module. The applied method in this research is combination of fuzzy logic and neural network or it is always mentioned as neuro fuzzy method using Matlab software version 7.1. The used data in this research is time series data January 2015 to December 2015, its independent variable is temperature that affect the dependent varable, it is the output power of photovoltaic and based on the simultant that it is effect on the power. The research result shows that the temperature is very effect on the output power of photovoltaic. From this testing is analyzed base on the average error value following the membership function of trimf type is 0,15334. The membership function is that it has the least average error value, it is trimf type of 0,15334 with epoch of 50 and its membership function is 10. ABSTRACTPenelitian ini betujuan untuk menganalisis pengaruh temperatur terhadap daya keluaran modul fotovoltaik. Metode yang diterapkan dalam penelitian ini adalah pendekatan kombinasi logika fuzzy dan neural network (jaringan syaraf tiruan) atau disebut Model Neuro Fuzzy dengan menggunakan program Matlab versi 7,1. Data yang digunakan dalam penelitian ini adalah data time series yaitu Januari 2015 sampai Desember 2015, variabel independen nya yaitu temperatur berpengaruh terhadap variabel dependen nya yaitu daya keluaran pada modul fotovoltaik dan secara simultan berpengaruh terhadap daya. Hasil penelitian ini menunjukkan bahwa temperatur sangat berpengaruh terhadap daya keluaran fotovoltaik. Dari pengujian ini dianalisis dengan nilai error rata-rata berdasarkan fungsi keanggotaan tipe Trimf (Segitiga) adalah 0,15334, Fungsi keanggotaan adalah nilai error rata yang terkecil dengan fungsi keanggotaan Trimf (Segitiga) yaitu 0,15334 dengan epochs 50 dengan jumlah fungsi keanggotaan sebanyak 10.

A fuel cell stack (FCS) converts the chemical energy to be the electrical energy through an electrochemical process. One type of FCS is proton exchange membrane (PEM) with hydrogen and oxygen as the main chemical energy source. The PEMFCS has been applied widely for operating direct current (DC) loads. However, the optimum sizing of FCS, DC load and the other supported devices are not considered well, thus the system performance does not have function optimum fully. This paper present the FCS integrated by boosted DC-DC converter for running DC load. The optimum sizing of FCS and boosted DC-DC converter are explained to obtain the required number of FCS and boosted DC-DC converter. A simulation of the FCS integrated boosted DC-DC converter is conducted using SIMULINK MATLAB. The simulation results show that the FCS and boosted DC-DC converter have good performance in the operation of DC load.

Batik is also an Indonesian cultural heritage whose manufacturing process uses the method of dyeing cloth with wax to hold the dye. The cloth is coated with wax and then colored. In addition, a lot of batik waste is wasted and causes environmental pollution. This environmental pollution starts from the beginning of the production process, namely the selection of raw materials, wasteful use of raw materials, water, and energy to limited quality in the final stages of the production process which results in an increase in the quantity of failed products. Therefore, the Community Service Team wanted to use the waste generated from the batik production process to be used as wood putty. The socialization and practice held by the community service team can increase the income of the people in the Tanjong Rejo, especially mangrove batik craftsmen.
