    Purpose of this research is to exploit the shell and palm fiber become the active charcoal, by looking at the influence of the ratio mixture composition and effect of activator. this Active charcoal application as adsorbent to the liquid waste of crude palm oil. Initial treatment, shells and palm fiber dried first at a temperature of 1200C and carbonized. charcoal mix shell and palm fiber activation chemically with a solution of H2SO4 by way of immersed in the solution for 24 hours. The best quality activated charcoal obtained from the comparison of the 75% shell, 25% palm fiber with activator H2SO4 that has a yield of 95.94%, 4.9% moisture content, ash content 6.13%, iodine number 916.594 mg / g. Activated charcoal mixture palm shell and palm fiber can be used as adsorbent liquid waste CPO, which is indicated by a decline in these parameters in the waste water contaminants in CPO, which is a 7.49 pH of 9, TSS of 660 ppm to 325 ppm,COD becomes 237,12 mg/L from1577.60 mg/L

    Tujuan dari penelitian ini adalah untuk mendeskripsikan: profil kematian ibu dan bayi baru lahir, (2) pelaksanaan program EMAS dari perspektif gender, dan (3) strategi komunikasi dalam melaksanakan program EMAS dari perspektif gender. Penelitian bersifat deskriptif kualitatif. Lokasi penelitian di Kabupaten Brebes. Informan penelitian ini ditentukan dengan purposive sampling. Data dikumpulkan melalui observasi, wawancara, studi dokumen dan Diskusi Kelompok Terarah. Analisis menerapkan sistem analisis model interaktif. Temuan menunjukkan bahwa tingkat kematian ibu dan bayi baru lahir masih tinggi. Itu sebabnya pemerintah daerah masih berjuang untuk meningkatkan kualitas kesehatan perempuan. Untuk mencapai tujuan mengurangi tingkat kematian ibu, strategi komunikasi dirancang khusus dalam setiap program baris melalui: (1) meningkatkan kualitas pelayanan klinis dan manajemen dengan memproduksi peraturan dan sosialisasi melalui berbagai forum dan media, menciptakan jaringan dan koordinasi dengan stakeholder terkait, memfasilitasi untuk menghasilkan buku handout dan lokakarya; (2) sistem rujukan darurat diimplementasikan dengan teknologi informasi berbasis selular disebut SIJARIEMAS, yang ternyata menunjukkan hasil yang tidak optimal; (3) strategi komunikasi dirancang dengan memberdayakan organisasi sosial dan keagamaan seperti komunikator kesehatan, pendidik dan motivator di mana ia masih mengidentifikasi beberapa kendala dalam menerapkan jalur komunikasi , yang menunjukkan bahwa angka kesehatan rendah, kepercayaan tinggi pada mitos dan persepsi bahwa melahirkan bayi adalah kodrat wanita dan budaya patriarki

    This research aims to find out the relationship of religiosity and emotional intelligence with juvenile delinquency. Subject of research is the students who sit in class VIII SMP Negeri 1 Kediri. The population was 997 people research but researchers only took a sample of 99 people. Research data collected by using the tools in the form of three scale corresponds to the number of variables is to study the scale of religiosity, emotional intelligence scale and the scale of juvenile delinquency. Of 99 pieces of the scale has been dispensed so as much as 86 pieces of the back. After checking the feasibility of such a scale, then the test is done by using correlation program SPSS version 16. The results showed that there is no relationship between religiosity and juvenile delinquency. Similarly, there is no relationship between emotional intelligence dan juvenile delinquency

    Besiq Bermai Forest is part of Kalimantan forests known for vast plant diversity. The present study aimed to investigate flora diversity, composition, and ecology in Besiq Bermai Forest to support the management of biodiversity and forest conservation. Thirteen plots were established with different sizes of plots (100 m x 20 m plots for trees; 40 m x 5 m plots for saplings; and 5 m x 5 m plots for understory). Data recorded included plant species name and individual number of each plant species. Data analysed were Shannon-Wiener diversity index, Relative Density, Relative Frequency, Relative Dominance and Important Value Index. The principal component analysis (PCA) was performed to determine relationship between edaphic components and flora occurrence. The results showed that there were 93 species of trees (belonging to 48 genera and 22 families), 112 species of saplings (belonging to 62 genera and 43 families), and 48 species of understory (belonging to 28 genera and 20 families). Shannon-Wiener diversity index (H') were 6.05, 6.25 and 3.26 for tree, saplings and understory, respectively. The most common family for tree and saplings in the forest ecosystem in this area was Dipterocarpaceae (Shorea spp). Species of tree with the highest importance value index were Dillenia excelsa, Syzygium sp. and Shorea parvifolia. The highest importance value index for species of saplings were Macaranga triloba and Shorea parvifolia; and for species of understory were Phrynium jagorianum. Ecological (edaphic) factors affecting the occurence and establishment of flora in Bermai forest were total N and C/N ratio. The present study has implication for the management of biodiversity and forest conservation

    A Brief Review on Thermal Behaviour of PANI as Additive in Heat Transfer Fluid

    Get PDF
    Since a decade ago, investigation on nanofluids has grown significantly owing to its enhanced thermal properties compared to conventional heat transfer fluids. This engineered nanofluid has been widely used in the thermal engineering system to improve their energy consumption by improving the thermal efficiency of the system. The addition of nano-size particles as additives dispersed in the base fluids proved to significantly either improve or diminish the behaviour of the base fluids. The behaviour of the base fluid highly depends on the properties of the additives material, such as morphology, size, and volume fraction. Among the variety of nanoparticles studied, the conducting polymers have been subject of high interest due to its high environmental stability, good electrical conductivity, antimicrobial, anti-corrosion property and significantly cheap compared to other nanoparticles. As such, the main objective of the present review is to provide an overview of the work performed on thermal properties performance of conducting polymers based nanofluids

    This paper investigates the influence of the electrolytic bath temperature on the morphology and physical properties of nickel (Ni) nanowires electrochemically deposited into the anodic alumina oxide porous membrane (AAO). The synthesis was performed using nickel sulfate hexahydrate (NiSO4.6H2O) and boric acid (H3BO3) as an electrolytic bath for the electrochemical deposition of Ni nanowires. During the experiment, the electrolyte bath temperature varied from 40°C, 80°C, and 120°C. After the electrochemical deposition process, AAO templates cleaned with distilled water preceding to dissolution in sodium hydroxide (NaOH) solution to obtain free-standing Ni nanowires. Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive Spectroscopy (EDX) and X-ray Diffraction (XRD) analysis were employed to characterize the morphology and physical properties of the synthesized Ni nanowires. Finding reveals the electrodeposition bath temperature significantly influences the morphology and physical properties of the synthesized Ni nanowires. Rougher surface texture, larger crystal size, and longer Ni nanowires obtained as the deposition bath temperature increased

    A preliminary study of human amniotic membrane as a potential chondrocyte carrier

    Purpose: To investigate the feasibility of using processed human amniotic membrane (HAM) to support the attachment and proliferation of chondrocytes in vitro which in turn can be utilised as a cell delivery vehicle in tissue engineering applications. Methods: Fresh HAM obtained from patients undergoing routine elective caesarean sections was harvested, processed and dried using either freeze drying (FD) or air drying (AD) methods prior to sterilisation by gamma irradiation. Isolated, processed and characterised rabbit autologous chondrocytes were seeded on processed HAM and cultured for up to three weeks. Cell attachment and proliferation were examined qualitatively using inverted brightfield microscopy. Results: Processed HAM appeared to allow cell attachment when implanted with chondrocytes. Although cells seeded on AD and FD HAM did not appear to attach as strongly as those seeded on glycerol preserved intact human amniotic membrane, these cells to be proliferated in cell culture conditions. Conclusion: Preliminary results show that processed HAM promotes chondrocyte attachment and proliferation
