The aim of this research identified the number of household industries in the food processing and knew the Good Manufacturing Practices(GMP) application of the household industry in the food processing in Kota Gorontalo. This research was carried out for 6 (six) month, in Kota Gorontalo. The household industry that was made the sample was household industry that was involved in the food processing. The method of the data collection was in this research carried out with the direct interview with used quisioner, the registration of the data that was related to the research from agencies, and observation that is observing directly the object of the research. The data that was gathered was edited afterwards was analysed with the descriptive method. Results survey the beginning showed the number of household industries of food processing in Kota Gorontalo totalling 7 (seven) industries with 90% of the kind of the end product is snack. The GMP application to the household industry of food processing in Kota Gorontalo most were carried out in accordance with the rules of GMP.. To receive certification must be carried out by the correction towards the layout regulation of the production, the cleanliness warning, the handling of the waste.

Diabetes mellitus was a degenerative disease with a high prevalence that happened in many countries. Several studies had been done to control diabetes by using such as green tea, mulberry leaftea, and their mixtures. The aim of this study was investigated the effect of black tea green tea mulberry tea and their mixtures on glycosilated hemoglobin and insulin level. This experiment used fourty two rats, aged2.5-3.0 months, 150-200 g bw. The rats were divided into 7 groups, each group consisted of 3 rats, namely; normally control group, negative control group, black tea group, green tea group, mulberry leaf tea group, black tea+mulberry leaf tea group and green tea+mulberry leaf tea group. The study was carried out for 16 days intervention. The dose of alloxan 125 mg/kg bw were given by intraperitonial. After blood glucose level >200 mg/dl, rats were given tea with dose I ml/day/100 g bw. The results were showed that toa treatments were not significantly (p>0,05) affected to glycosilated hemoglobin level [HbAlc) and insulin level from rats blood.

A series testing of the integrated design of biomass furnace and heat exchanger was conducted to see the performance using methods such as the effectivenes-number of transfer unit (e-NTU),  the efficiency as a function of Fin Analogy Number (h(Fa)) and the log-mean temperature difference (LMTD). The biomass furnace as a plant to generated heat produced value of energy 25,600W with the burning rated of corncob 7.03 kg/hour. The calculation of amount of heat transfer to the cold fluid in the tubes as function of fluid characteristic, mass rated of dry air in a longitudinal section was 11,285W. The effectivenes as the ratio of actual heat transfered to the absolute maximum heat that can be transferred in a heat exchanger was 0.90. The efficiency of heat exchanger as a clear measurement of performance system was 0.78. The efficiency as a function of fin analogy number, employed several variable as it function; such as the product of UA, minimum heat capacity rate (Cmin) and the capacity ratio (Cr). Another performance showed by correction factor with value of 0.5 indicated that the heat exchanger was not a pure of counter-flow but made of cross-flow in the single segmental baffle with turbulances pattern (Re: 8.524 > 6.000).ABSTRAKSerangkaian pengujian terhadap desain terintegrasi tungku biomassa dan penukar panas telah dilakukan untuk melihat performansinya menggunakan metode efektifitas-NTU (e-NTU), efisiensi sebagai fungsi dari fin analogy number (h(Fa)) dan beda temperatur rata-rata logaritmik (LMTD). Tungku biomassa sebagai pembangkit panas menghasilkan energi senilai 25.600W dengan laju pembakaran tongkol jagung 7.03 kg/jam. Perhitungan laju pindah panas ke fluida dingin dalam pipa sebagai fungsi dari karakteristik udara, laju massa melalui luas penampang laluan diperoleh sebesar 11,285W. Efektivitas sebagai rasio laju pindah panas aktual dengan panas maksimum yang dapat dipindahkan dalam sebuah penukar panas diperoleh sebesar 0,90. Efisiensi penukar panas sebagai ukuran jelas performansi sistem diperoleh sebesar 0,78. Efisiensi dalam hal ini adalah fungsi dari fin analogy number sedangkan fin analogy number merupakan fungsi dari beberapa variabel seperti hasil perkalian UA, laju kapasitas panas minimum (Cmin) dan rasio kapasitas (Cr). Performansi lainnya ditunjukkan melalui nilai faktor koreksi sebesar 0,5 menunjukkan bahwa penukar panas tidak sepenuhnya merupakan aliran-melawan melainkan terbentuk aliran-silang khususnya di dalam ruang antar sekat dengan pola turbulensi (Re: 8.524 > 6.000).

Traditional food products are no longer attractive to the public, so it needs innovation to ensure that the products have a functional value. The aim of this research is to produce fortified cornmeal with kersen (Muntingia calabura L.) leaf extract which has high antioxidant activity and consumer demand of organoleptics. This research used a completely randomized design with single factor at 6 treatment levels, soaking grits of corn on cherry extract with 0%; 10%; 20%; 30%; 40%; and 50% concentrations. The results of nutrient analysis showed that protein contents ranged from 7.59% ? 8.93%; fat 0.53%?0.96%; ash content 0.05%?0.12%; water content 11.6%?13.37%; and carbohydrate 77.24%?78.91%. The result of antioxidant activity showed that the higher concentration of kersen leaf extract added the higher also the antioxidant activity of fortified cornmeal, between 11.85?36.17%. Based on panelists? organoleptic test, most gave neutral response to like slightly for color, texture, aroma and overall grits, while for the panelists, while for taste they gave dislike slightly response.
