Abstract

Persalinan lama menyebabkan terjadinya komplikasi persalinan seperti perdarahan. danpartus lama. Salah satu sumber makanan yang mengandung kalori tinggi adalah madu dari kurma dan anggur merah serta air gula . Glukosa yang tinggi pada kurma dan anggur merah bermanfaat untuk tenaga. Serotonin ,tannin dan oksitosin pada kurma membantu kontraksi otot polos rahim pada persalinan .Madu dan anggur merah merupakan fruktosa dan glukosa sumber energi instan bagi tubuh. Tujuan penelitian untuk mengetahui manfaat madu kurma dan madu anggur merah pada lama persalinan kala I aktif, Jenis penelitian ini adalah quasi eksperimen dengan desain posttest only with control group design. Penelitian ini dilakukan di Puskesmas Secang II dengan populasi 60 ibu bersalin yang melahirkan pada bulan September sampai Nopember 2022 teknik pengambilan sampel total sampling dengam jumlah sampel kelompok intervensi ibu bersalin kala I aktif yang diberikan madu kurma dan kelompok kontrol ibu bersalin kala I aktif yang diberikan madu anggur merah jumlah 30 responden . Hasil penelitian terdapat perbedaan pemberian kombinasi madu kurma dan anggur merah terhadap lama persalinan kala 1 aktifp value 0,030. Nilai Z Score -2.164 pemberian madu kurma lebih efektif mempercepat lama persalinan kala 1 didaptkan juga mean madu kurma 22,3667 menit dibandingkan madu anggur merah mean 31,0833 menit. Madu kurma maupun madu anggur sama sama efektif walaupun ada perbedaan . Disarankan sebagai tambahan energy tambahkan kurma madu maupun madu anggur merah pada ibu bersalin untuk memperpendek waktu persalinan kala 1 aktif

Abstract

Mixed Hydroxide Precipitate (MHP), a metal precipitate with the dominant nickel and cobalt content in hydroxide compounds, can be leached as a lithium battery precursor. In this study, KMnO4 was used as an oxidant agent to increase the solubility of Ni and Co. The variation of the sulfuric acid concentration (0.5 - 1.5 M) as a leachate reagent, the concentration of KMnO4 (2.5 - 7.5 g/L), and the selective leaching temperature (60 - 80°C) were investigated. Solvent extraction using CYANEX 272 and D2EHPA was performed to separate the Ni, Co, and Mn. Atomic Absorption Spectrometry (AAS), Inductively coupled plasma mass (ICP-OES), and X-ray Fluorescence (XRF) were used to analyze the chemical compositions. At the same time, crystallographic analysis was observed with X-Ray Diffraction. It was observed that potassium permanganate increased the dissolution of Ni and Co to 91.3% and 85.4% but decreased the dissolution of Mn (37.53%) under the following conditions: 1.75 M sulfuric acid, 7.5 g/L potassium permanganate, and 60°C temperature. High purity of nickel crystal (99.64%) was observed with spontaneous nucleation due to the supersaturated nickel solution after solvent extraction with CYANEX 272. Thus, using permanganate ion as selective leaching of Ni and Co from Mn is promising.

Abstract

Biochar is a solid material produced by thermochemical conversion of biomass under oxygen-limited conditions. It has a wide surface and contains many pores so that it can be used as a material for making fertilizer. Biochar based slow release NPK fertilizer was formulated and developed to reduce nutrient leaching and greenhouse gas emissions. In this research, biochar which was a by-product of biomass gasification using oil palm empty fruit bunches was processed to make slow release biochar NPK fertilizer. Sources of nitrogen (N) were derived from urea, phosphate (P) from diamonium phosphate (DAP) and potassium (K) derived from potassium chloride (KCl). Zeolite was added as a matrix to improve fertilizer characteristics. All materials were formulated to make slow release biochar NPK fertilizer used for red onion (Allium sepa) plant applications. Several micronutrients were also added including Mg (MgSO4 fertilizer) and S (ZA fertilizer) to support plant growth. The characterization of fertilizer products was carried out by using SEM, BET etc. to determine physical properties including surface area, pore volume, morphology and composition. Furthermore, biochar NPK fertilizer was applied to the red onion plant which was a high-value crop in Indonesia. The application of NPK biochar fertilizer on red onion plant showed its superiority compared to commercial NPK fertilizers. In addition, the use of Magnesium and sulfur micronutrients could support the growth of red onion bulbs so that they produced more and bigger bulbs.*The paper has been selected from a collaboration with IPST and 7th ICFCHT 2019 for a conference entitled "Innovation in Polymer Science and Technology (IPST) 2019 in Conjunction with 7th International Conference on Fuel Cell and Hydrogen Technology (ICFCHT 2019) on October 16th - 19th at The Stones Hotel Legian, Bali, Indonesia"

Abstract

This study focuses on the synthesis and performance evaluation of silica membranes supported on ?-–alumina flat disks for bio–CNG (CO2/CH4) purification. The membranes were fabricated via a sol–gel method using tetraethyl orthosilicate (TEOS) as the silica precursor and cetyltrimethylammonium bromide (CTAB) as the templating agent. CTAB concentrations were varied from 0.01 to 0.09 M, while drying temperatures ranged from 80 to 120 °C. Characterisation through SEM–EDX, XRD, and gas permeation tests revealed that an increase in CTAB concentration produced a more uniform pore structure and enhanced CH4 flux. However, excessive CTAB led to over–templating, resulting in microcracks. The optimal membrane was obtained at 0.05 M CTAB and a drying temperature of 105 °C, yielding a separation factor (?- = 2.14) with stable structural integrity. Gas transport was dominated by Knudsen diffusion, favouring CH4 over CO2, with an experimental CH2/CO4 selectivity (?- = 3.21) exceeding the theoretical Knudsen value (1.66). This indicates that, in addition to Knudsen flow, microstructural factors such as pore interconnectivity and partial defects contributed to CH4 transport through the silica membrane. These findings indicate that silica membranes synthesised under optimised sol–gel conditions exhibit strong potential for efficient bio–CNG upgrading, supporting renewable, low–carbon energy applications.
