  • Characteristics of Self Compacting Concrete (SCC) by the Silica Fume as
           Portland Cement Substitute

    • Authors: Herliati Rahman, Puput Dwi Rahayu
      Abstract: Self-compacting concrete (SCC) is a type of concrete that can flow by itself and can self-compact without using a compactor such as a vibrator. This study aims to observe the effect of cement substitution with silica fume on the compressive strength of concrete. The researchers expect a compressive strength of Self Compacting Concrete up to 500 kg/cm2, although silica fume substituted some portland cement. In order to reduce water use while maintaining the slump flow value of 60±2 cm, a superplasticizer was added at the fixed composition of 1.2% (w/w). The experimental design of silica fume as a cement substitute with a variation of 0%, 5%, 10%, and 15% (w/w). The concrete compressive strength test is carried out under the ASTM C234 standard, while the slump flow value refers to the ASTM C494 standard and the British Standard 5075. Although there was no compressive strength of 500 kg/m2 for all types of cement obtained, it shows that the highest compressive strength of SCC concrete was in the type of OPC cement at 28 days of age.

  • PERBANDINGAN AKTIVITAS EKSTRAK DAUN TAPAK DARA (Catharanthus Roseus) DAN
           TBHQ SEBAGAI ANTIOKSIDAN MINYAK GORENG TERHADAP FOTOOKSIDASI UV-C

    • Authors: Akhmad Al-Bari, Romadhiyana Kisno Saputri
      Abstract: Cooking oil is one of the sources of human energy with a total consumption of 290 million tons/year by the public. The largest use of cooking oil is the household sector which generally gets its oil from traditional markets. The oil that is traded in the market is often not covered properly so that it is easily exposed to sunlight. The light that hits the oil can cause damage, including the formation of peroxide compounds. Efforts to overcome the damage include adding natural antioxidants as an alternative to synthetic antioxidants. This study aims to determine the impact of 254nm ultraviolet photooxidation on the containment of oil oxidation by the addition of tapak Dara leaf extract and TBHQ. The oil was photo oxidized with variations of 1, 3, 6, and 12 hours to determine the hold. To determine the quality of the oil, three parameters of sample testing were carried out, namely free fatty acid content, peroxide number, and water content. The results of photooxidation showed that cooking oil with tapak Dara leaf extract had lower holding activity than TBHQ. This value was measured on the peroxide number and free fatty acid content, while the measurement of the water content of the measured containment activity was better with a value that met SNI, namely <0.1%

           sebagai Agen Pengkelat Ion Logam Tembaga

    • Authors: Muhsinun Muhsinun, Fena Prayunisa
      Abstract: One of the way to recycle heavy metals in the prevention of environmental pollution is by using a solid-liquid extraction method through the impregnation mechanism of chelating agent in the adsorbent to increase its ability to bind heavy metal ions. In this study, the impregnation of fatty hydroxamic acids (FHA) successfully carried out on active natural zeolite (ZAA). This is has been done to increase the maximum adsorption capacity of ZAA towards heavy metals. The purpose of this study was to examine the adsorption ability of FHA impregnated onto ZAA as a chelating agent in copper metal ions by using column chromatography. This column contains FHA, which synthesized from crude rice bran oil and impregnated onto ZAA. There are several parameters were investigated, they are, the effect of FHA concentration, mass of FHA-ZAA resin and pH of the metal ion sample. From this study, the concentration of FHA impregnated on the zeolite surface reached 41.60%. The optimum conditions for Cu(II) adsorption by FHA-ZAA were as follows: mass ratio of FHA-ZAA resin with Cu(II) concentration (g : ppm) was 1:100 and the optimum condition of Cu(II) ion was at pH 5

    • Authors: Alfiah Alif, Dyah Iswantini, Henny Purwaningsih, Novik Nurhidayat, Amalyah Febryanti
      Abstract: Benzene is one of the harmful compounds which can affect both healthcare and environmental quality. Conventionally the effort of detecting this compound still requires several sample pre-treatments, contributing to a long analysis time and sophisticated instrumentation. Therefore, this study was aimed to determine the potency of bacteria as the bioreceptor for detecting benzene electrochemically. The bacteria isolate was immobilized on the working electrode surface. Four bacteria isolates from the petroleum sample were evaluated. The results showed that isolate II produced high oxidation and reduction peak currents as much as 150 µA and -490 µA respectively. The selected bacteria showed characteristics to Pseudomonas sp. physiologically. Since the bacteria can degrade benzene, thus hypothetically it can produce benzene dioxygenase. Through the catechol formation, 3 mM benzene produced 108.7 µA after 11.4 s from the starting scan. This result suggested that the excreted enzyme from the selected bacteria could react with benzene enzymatically.

  • Docking Molecular dari Kompleks Zn(II)Amina (Prolin)dithiokarbamat
           terhadap Reseptor Estrogen-α

    • Authors: Rizal Irfandi, Ruslang Ruslang, Indah Raya, Ahamd Yani, Muhammad Nasir, Nurcaya Nurcaya, Sulistiani Jarre
      Abstract: Estrogen-α (ER-α) is a major target in cancer therapy. Targeting the ER-α target protein is known to slow the proliferation of breast cancer cells. The purpose of this study was to determine the interaction of the complex compound Zn(II)Prolinedithiocarbamate against the Estrogen-α Receptor. The Zn(II)Prolinedithiocarbamate complex was predicted canonical SMILE by Cheminfo online application (O=C(O)C1CCCN1C2S[Zn]S2) and modeled with online corina to obtain a three-dimensional structure. The structure of the complex compound Zn(II)Prolinedithiocarbamate interacted with Estrogen receptor alpha protein to test its potential anticancer activity. Molecular docking results show the interaction of the Zn(II)Prolinedithiocarbamate complex with the Estrogen- receptor on the amino acid residues ARG394, LEU387, GLU353, LEU346, LEU349, and PHE404. The Zn(II)Prolinedithiocarbamate complex interacts directly with ER-α in the estrogen region which causes the failure of the interaction between estrogen and the estrogen receptor, so it can be predicted that the Zn complex has activity as an ER-α inhibitor and has the potential to be developed in the treatment of breast cancer.

  • Perbandingan Efektivitas Bioadsorben Berbagai Serbuk Kulit Buah Terhadap
           Logam Pb Dari Limbah Cair Laboratorium Farmasi

    • Authors: Hesty Nuur Hanifah, Ginayanti Hadisoebroto
      Abstract: Pharmaceutical laboratory liquid waste is a source of heavy metal contaminants that can be harmful to living things if not treated properly. One of these heavy metals is lead (Pb), which if accumulated in the body can cause kidney disorders, nerves and even death. Utilization of bioadsorbents derived from biomass in the form of fruit peels can be a solution because they generally contain compounds that have functional groups that can bind to metals. The purpose of this study was to reduce Pb levels in liquid waste using a biomass waste adsorbent made from five) kinds of fruit peel powder, namely jackfruit peel, salak, durian, banana and watermelon.. The adsorption process must be carried out under optimal conditions, by varying the pH factor, immersion time and mass of the bioadsorbent powder. Measurement of Pb levels was carried out using Atomic Absorption Spectrophotometer (AAS) at a wavelength of 283.3 nm. The results showed that the highest adsorption effectiveness was obtained using jackfruit peel powder, which was 94.74%,. While the lowest adsorption effectiveness was using banana peel powder, which was 57.29. The adsorption effectiveness of watermelon, salak and durian peel were 91.52%, 90.5% and 63.74%, respectively.

      Abstract: Acute Respiratory Infection (ARI) is an acute inflammation of the upper or lower respiratory tract caused by bacterial, viral, fungal and other parasitic infections. Lemon peels have been reported to contain beneficial compounds such as phenolic compounds and flavonoids. Flavonoids have been reported to have antioxidant, antibacterial, antiviral, anti-inflammatory, anti-allergic and anticancer activities. The review was conducted to select the orange peel from the best type of orange that can be used as an inhaler for people with ARI. National and international journals were selected based on the keywords citrus peel, antibacterial and antiviral. The chemical components reported in the essential oils of various citrus peels were determined and correlated with their related activity as antibacterial and antiviral. This systematic review shows that compounds that have the potential as antimicrobial, antibacterial and antiviral are flavonoids and limonina, these compounds are widely contained in the essential oil of lemon peel. The conclusion of the review shows that lemon peel essential oil has the potential as a raw material for anti-ARI drugs.
