Publisher : Kementerian Perindustrian

The quality of rubber cup lump is ditermined by several factors, one of them is the latex coagulant. The type of latex coagulant also affects the coagulating time. Liquid smoke is one of the most recommended latex coagulants due its save and effective operation. Deorub, the most popular liquid smoke, is made from shell of oil palm kernel. There are still many alternatives of liquid smoke materials that may have lower economic values. This study was aimed to evaluate and compare the performance of three liquid smokes produced from three alternative materials namely galam wood, rubber wood, and oil palm frond as latex coagulants. This study was performed using groups random design with two factors, namely type of coagulants and the concentrations (10% and 5%). Evalution was performed on the speed of coagulating time and also the quality of rubber cup lumps resulted by the tested coagulants, such as water content, rubber dry weight, ash content, and also the value of sensory quality (smell, color, texture, and the bubble). Liquid smoke resulted from oil palm fronds showed the best performance due to itâ€™s lowest pH value (2.5) and the shorthest coagulating time (40 min) at concentration of 10%, which produced rubber lumps with rubber dry weight of 99.86% and ash content of 0.83%. Meanwhile, the highest yield of liquid smoke was resulted from galam wood (10%) with coagulating time of 72 minutes.

Kalakai (Stenochlaena palustris) is a fern that lives wildly in nature. High iron content in the diet underlies the use of kalakai plants as a natural iron fortifying food for growing children. The purpose of this study was to determine the best formulation of baby porridge flour meeting the Indonesian National Standard (SNI). Kalakai was selected as a Fe fortifying material due to its high content of Fe. Three formulations (A, B, and C) were produced from three different flours (cassava nagara, kalakai, and young banana), and the formulated samples were tested. Formula A was 55 (cassava) : 5 (kalakai) : 40 (banana); formula B was 57:3:40; and formula C was 59:1:40. Those three formulations were compared with a control which was made from cassava nagara flour and banana flour with ratio of 60% and 40% (without kalakai). The results showed that the best formula was the A formulation, with a ratio content of 55:5:40. This formula had 0.90 g/ml of kamba density, 2.04 of water absorption index, 6.62% of moisture content, 3.02% of ash content, 0.67% of fat content, 2.41% of crude protein, and 4.48 mg/100g of Fe level.

AbstrakAntioksidan memiliki peran penting dalam mengurangi potensi terjadinya penyakit degeneratif. Penelitian ini bertujuan menambahkan sumber antioksidan bioflavonoid dari ekstrak patikan kebo (Euphorbia hirta L) pada gula semut aren. Ekstrak padat patikan kebo diperoleh melalui proses refluks sampel kering pada pelarut etanol 96% yang dilanjutkan proses evaporasi. Penambahan empat tingkat konsentrasi ekstrak (0,5%; 1,0%; 1,5%; 2,0%) diuji pengaruhnya terhadap karakteristik sensori (scoring dan hedonik) dan kimia (kandungan bioflavonoid, kadar air, kadar abu, dan gula pereduksi). Keberadaan bioflavonoid (myricitrin dan quercitrin) dianalisis melalui metode kromatografi lapis tipis (KLT), sedangkan konsentrasinya dianalisis secara teoritis berdasarkan kandungan myricitrin dan quercitrin pada ekstrak etanol 96% dari hasil penelitian sebelumnya. Hasil pengujian perbedaan konsentrasi ekstrak menunjukkan pengaruh nyata terhadap mutu sensori (rasa, warna, dan aroma). Semakin tinggi konsentrasi ekstrak yang ditambahkan, semakin menurunkan mutu sensorinya. Aspek mutu sensori, antara rasio 0,5% dan 1,0% tidak berbeda signifikan dan masih menunjukkan daya terima yang baik, namun rasio 1,0% memiliki kandungan bioflavonoid yang lebih tinggi. Penambahan 1,0% ekstrak patikan kebo direkomendasikan sebagai tingkat yang tepat, yaitu mengandung bioflavonoid myricitrin dan quercitrin masing-masing sebesar 3,8 mg/g dan 1,0 mg/g gula semut. Analisis biaya menunjukkan harga pokok produksi untuk penambahan ekstrak 1,0% adalah sebesar Rp110.000,00/kg.Kata kunci: bioflavonoid, Euphorbia hirta, gula semut aren, myricitrin, quercitrin AbstractAntioxidant plays important roles in the reduction of degenerative diseases. This study aimed to formulate bioflavonoid antioxidant from Euphorbia hirta on granulated palm sugar. Extract of E. hirta was obtained by reflux extraction with 96% ethanol. Granulated palm sugars fortified with four concentration levels of E. hirta extract (0.5%; 1.0%; 1.5%; 2.0%) were evaluated for the sensory and chemical characteristics including water content, ash content, reducing sugar, and the presence of bioflavonoid. The content of bioflavonoids (quercitrin and myricitrin) were also calculated based on the content of those compounds in the ethanol extract as identified in the previous study. The presence of bioflavonoid was identified by thin layer chromatography test. Statistical analysis showed that addition of different concentration level of extract to the sugar significantly affect the sensory characteristics. Higher concentration of extract decreased the sensory level. Nevertheless, between concentration of 0.5% and 1.0% were not significantly different, and surely, the higher concentration will provide higher bioflavonoid content. Addition of 1.0% E. hirta extract was recommended due to the higher content of quercitrin and myricitrin (3.8 mg/g and 1.0 mg/g, respectively) with the adequate sensory characteristic. Production of granulated palm sugar fortified with 1.0% E. hirta extract required IDR110,000.00/kg.Keywords: bioflavonoid, Euphorbia hirta, granulated palm sugar, myricitrin, quercitrin

The selective conversion of 2-methylfuran (2-MeF) to 1,4-pentanediol (1,4-PeD) over bimetallic nickel-tin alloy catalysts in the ethanol/H2O solvent mixture was studied. By using bulk Ni-Sn(x); x = 3.0 and 1.5 catalysts, a maximum yield of 1,4-PeD (49%) was obtained at 94% conversion of 2-MeF. The dispersion of Ni-Sn(x) on the aluminium hydroxide (AlOH) or g-Al2O3 supports allowed to an outstanding yield of 1,4-PeD (up to 64%) at 433 K, 3.0 MPa of H2 within 12 h. Ni-Sn(3.0)/AlOH catalyst was found to be reusable and the treatment of the recovered Ni-Sn(3.0)/AlOH catalyst with H2 at 673 K for 1 h restored the catalyst’s original activity and selectivity.

Selective hydrogenation of dodecanoic acid over supported bimetallic Ni-Sn alloy catalysts into dodecane-1-ol is demonstrated. Bimetallic nickel-tin supported on titanium oxide (Ni-Sn(1.5)/TiO2) and gamma-alumina (Ni-Sn(1.5)/g-Al2O3); 1.5 = Ni/Sn molar ratio) were synthesized via hydrothermal method in a sealed-Teflon autoclave reactor at 150 oC for 24 h, then followed by reducing with hydrogen gas at 400 oC for 1.5 h. The synthesized catalysts were characterized by means of XRD, IC-AES, N2-adsorption (BET method), H2-chemisorption, and NH3-TPD. Bimetallic Ni-Sn(1.5)/TiO2 catalyst was found to be effective for hydrogenation of dodecanoic acid (>99 % conversion) to dodecane-1-ol (93% yield) at 160 oC, 30 bar H2, and 20 h and the highest dodecane-1-ol (97 % yield) was obtained at initial pressure of H2, 50 bar. An increase of reaction temperature slightly enhanced the degree of hydrodeoxygenation of dodecanoic acid to produce dodecane over both Ni-Sn(1.5)/TiO2 and Ni-Sn(1.5)/g-Al2O3 catalysts.
