This study aims to determine the effect of giving Iles-iles synbiotic effervescent tablets to decrease blood sugar levels of hyperglycemic white rats and find out the lowest dose of effervescent tablets in decreasing blood sugar levels. This study used the Completely Randomized Design (CRD) with single factor (dose of Iles-iles synbiotic effervescent tablet) with 4 levels (dose 0.045 gram/day (½ normal dose), dose 0.09 gram/day (normal dose), dose 0.18 gram/day (2X normal dose) and Control (without treatment dose). The analysis carried out was blood sugar levels and rat body weight. The administration of Iles-iles synbiotic effervescent tablets can reduce blood sugar levels in white mice but does not affect changes in the weight of white mice. The biggest decrease in blood sugar levels in white rats for synbiotic month was obtained from the administration of a dose of 0.18 grams/day (normal 2X dose) which was as much as 49.16% The administration of effervescent tablets in the fourth week with a normal dose of 0.09 grams/200 grams of weight has been able to reduce blood sugar levels in white rats to normal levels.
Monolaurin is a monoacylglycerol, which can act as an emulsifier and antibacterial. Palm kernel oil is a monolaurin raw material that can be fractionated into palm kernel olein (PKOo) and palm kernel stearin (PKS). Therefore, this study prepares monolaurin through enzymatic glycerolysis of the PKOo-PKS blend. The effects of enzyme concentration, molar ratio of oil to glycerol, solvent to oil ratio, and reaction temperature on the products of glycerolysis were investigated. The best conditions were selected for further production, purification, and characterization of the monolaurin. The results showed that the best glycerolysis condition was obtained with an enzyme concentration of 10% w/w, an oil–glycerol molar ratio of 1:4, a solvent–oil ratio of 2:1 v/w, and a glycerolysis temperature of 40 °C with a stirring speed of 600 rpm based on the monoacylglycerol (MAG) concentration. The identification of the sample with FTIR and NMR indicated that the purified glycerolysis product is the monolaurin. The thermal analysis showed a large endothermic peak with a melting point of 35.56 °C. The purified monolaurin has a HLB value of 5.92, and an emulsion capacity and stability of 93.66 ± 1.85% and 89.54 ± 3.36%, respectively. The minimum inhibitory concentration (MIC) of the monolaurin for Escherichia coli FNCC 0091 and Staphylococcus aureus FNCC 0047 were at 500 ppm, and 100 ppm for Bacillus subtilis FNCC 0060.
Oil palm empty fruit bunches (OPEFB) can be used as raw material for Hydroxypropyl Methylcellulose (HPMC). HPMC can be used as a French fries coating to reduce oil uptake. This research aims to study the utilization of HPMC OPEFB as a French fries coating. This research consists of two stages. The first stage is cellulose extraction and HPMC synthesis. HPMC synthesis through alkalization, methylation, propylation, and neutralization. The second stage is the use of HPMC as a French fries coating with different concentrations (0, 1, 2, and 3%). Potatoes that have been peeled and washed, cut lengthwise with a thickness of about 0.5 cm. Further dipped in HPMC solution with different concentrations for 10 seconds, then carried out a frying pan. The HPMC from OPEFB is characterized by methyl and hydroxypropyl groups found at a wavenumber of 2891.30 cm -1 , a ring of pyranose at 995.79 cm -1 and hydroxyls (OH) groups at 3371.10 cm -1 . The coating of French fries with 3% HPMC OPEFB can reduce oil absorption by 16.09%. The higher the concentration of HPMC, will reduce the fat content but increase the moisture and the texture of French fries become softer. The preferred type of coating was HPMC 1%.
ABSTRAKProgram Kemitraan Masyarakat (PKM) dilaksanakan dengan mitra industri rumah tangga (IRT) Jahe Instan “Merapi Mantap" di Dusun Kinahrejo, Umbulharjo, Cangkringan, Sleman. Salah satu permasalahan yang dihadapi mitra adalah belum adanya mesin penggiling jahe dan belum adanya pengolahan limbah perasan jahe. Selama ini mitra selalu menggilingkan jahe ke pasar sehingga menambah biaya produksi. Selain itu limbah perasan jahe belum dimanfaatkan dan biasanya hanya dibuang di kebun. Oleh karena itu perlu dilakukan upaya untuk mengurangi biaya produksi dengan melakukan introduksi mesing penggiling jahe dan perlu dilakukan pelatihan untuk pengolahan limbah perasan jahe menjadi tepung jahe. Tujuan PKM ini adalah (1) introduksi dan pelatihan mesin penggiling jahe (2) pelatihan pengolahan limbah perasan jahe menjadi tepung jahe. Metode yang dilakukan menggunakan pendekatan partisipatif yang melibatkan mitra secara aktif, dengan tahapan pengadaan mesin penggiling jahe, pelatihan penggunaan mesin penggiling jahe dan pengolahan limbah perasan jahe menjadi bubuk jahe. Hasil kegiatan PKM ini adalah transfer teknologi tepat guna penggunaan mesin penggiling jahe dan pemanfaatan limbah jahe menjadi bubuk jahe dengan rendemen 18.5% dan kadar air sekitar 10%. Dampak kegiatan ini adalah adanya pengurangan biaya produksi untuk penggilingan jahe dan adanya produk tepung jahe yang dapat dimanfaatkan untuk berbagai produk. Dampak lingkungan yaitu dapat mengurangi pencemaran limbah. Kata kunci: mesin penggiling jahe; pengolahan limbah, bubuk jahe. ABSTRACTThis activity was implemented in domestic industry partners Jahe Instan "Merapi Mantap" in Kinahrejo Village, Umbulharjo, Cangkringan, Sleman. The problems is the absence of ginger grinding machines and the absence of ginger-based waste treatment. The partner always grinds ginger to the market so the cost of production increased. In addition, the waste of ginger squeeze is not utilized and usually only disposed of in the garden. The purpose of this activity is (1) introduction and training of ginger grinding machine (2) training of processing waste squeeze ginger into ginger powder. The method is carried out using a participatory approach, with the stage of making the procurement of ginger grinding machine, training the use of ginger grinding machine and conducting ginger squeeze waste treatment activities into ginger flour. The result of the activity is the transfer of appropriate technology regarding the use of ginger grinding machines and the utilization of ginger squeeze waste into ginger flour. The yield of ginger powder is 18.5% with water content about 10%. Impact of this activity is the reduction of production costs for ginger milling and the powder ginger as new product that can be utilized for various products. Environmental impacts can reduce waste pollution. Keywords: ginger grinding machine; waste treatment; ginger powder
