Abstract

Separation of titanium dioxide (TiO2) from ilmenite Bangka has been done byleaching processusing HCl. Before the leaching process, ilmenite was roastedat 900oC for pre-oxidation (preliminary - oxidation). Leaching process carried out by variation of HCl concentration and Fe0reducing agents. While the re-deposition of dissolved Ti4 +ionachieved by hydrolysis - condensation using 2- propanol - H2O solvents.Leaching the pre-oxidazed ilmenite shows the phase change of  pseudobrokite (Fe2TiO5 ) into hematite ( Fe2O3) and synthetic rutile ( TiO2 ). Formation of the synthetic rutile was characterized by the loss of intensity of Fe2TiO5 at 26.65 º and the increasing intensity of rutile TiO2 at 27.49 º.The dissolution rate of both titanium and iron wasfound to be increased, generally, by increasing acid concentration in case of HCl as well as by increasing ilmenite:Fe0 ratio. Precipitation ofthe dissolved titania with 2-propanol -H2Oof 8:2(v /v) produced anataseTiO2 due to the hydrolysis and condensation of Ti-tetraisopropoxide complexes.

Abstract

Research on the preparation and characterization of sulfonated polystyrene (PST) /chitosan vanillin (KV) composite as electrolyte membranes has been conducted in order to investigate the effect of PST and KV composition  to its chemical and physical properties. Polystyrene was modified by sulfonation reaction to produces PST, meanwhile chitosan was modified by schift base reaction to produces KV. The composite membranes were prepared by casting method and were characterized in order to identify the functional groups contained in the composite, the cation exchange capacity (CEC), the Swelling Degree (SD), the thermal properties and the morphology. The peak of imine vibration in the FTIR spectrum indicates that the chitosan vanilin was succesfully synthesized. Meanwhile, the peak of sulfonate vibration indicates the product of sulfonation on polystyrene. The result of CEC analysis shows that the addition of sulfonate groups on polystyrene and the addition of phenolic groups on chitosan increase the CEC value. The increasing of PST and KV concentration in membrane enhance the CEC value. However, the increasing of PST concentration in membrane composition even decrease the Swelling Degree of membranes. Meanwhile, the increasing of KV concentration increase the swelling degree of membranes. Thermal analysis shows that the thermal decomposition of membranes occurs in three stages i.e. the dehydration of water molecules, the degradation of the subtituen groups and the plasticizer and the degradation of the back bone of chitosan and polystyrene.

Abstract

The aims of the research are to prove that at certain conditions the reaction between Br2 with CH3COOH is similar to enzymatic reaction, and the value of   calculated from the Espenson equation is different with value calculated by integral method. The experiments were performed at various concentrations of CH3COOH. The reaction studied by spectroscopic method by record the changes in absorbance of Br2 at 400 nm (theabsorbance index is 160 M-1 cm-1) in each definited time range. Data were analyzed with integral equations and the reaction order was determined base on the value of regression coefficient which must be close to 1 or -1. The reaction is said to be similar to the enzymatic reaction if the order of the reaction at initial is different with the order value at the end of reaction. Data were also analyzed using Espenson and integral equation (for comparison). The results showed that at concentrations of CH3COOH 0.00150 M, 0.00100 M, and 0.00075 M and 0.00300 M Br2 the reaction is similar to enzymatic reactions. Meanwhile, at different concentrations of CH3COOH,  the κ value obtained from Espenson equation is different with the value calculated by integral method.

Abstract

Pembinaan anak yang berkonflik dengan hukum dibedakan dengan pembinaan terhadap warga binaan pemasyarakatan dewasa karena anak tidak sama dengan orang dewasa. Oleh karena itu, Lembaga Pembinaan Khusus Anak (LPKA) harus memisahkan ruangan antara anak-anak sesuai klasifikasi umur agar mereka tidak menjadi korban bullying, pelecehan, atau kekerasan lainnya. Penelitian ini bertujuan untuk menganalisis konsep usia di LPKA di Indonesia. Metode yang digunakan dalam penelitian ini adalah yuridis empiris dengan pendekatan yuridis sosiologis, yang mengidentifikasi dan mengkonsepsikan hukum sebagai institusi sosial yang nyata dan fungsional dalam sistem kehidupan hukum. Selain itu, pendekatan perbandingan (comparative approach) digunakan untuk membandingkan peraturan perundang-undangan di Indonesia dengan peraturan di negara lain. Hasil penelitian menunjukkan bahwa konsep usia anak yang menjadi kebijakan di LPKA di Indonesia didasarkan pada beberapa peraturan, termasuk Undang-Undang No. 4 Tahun 1979 tentang Kesejahteraan Anak pasal 1 ayat 2, Undang-Undang No. 35 Tahun 2014 (perubahan atas UU No. 23 Tahun 2002) tentang Perlindungan Anak pasal 1 ayat 1, Konvensi tentang Hak-hak Anak pasal 1, dan Undang-Undang No. 11 Tahun 2012 tentang Sistem Peradilan Pidana Anak.

Abstract

Condition-Based Monitoring (CBM) merupakan metode pemeliharaan prediktif yang mengandalkan pemantauan parameter operasional untuk mendeteksi dini potensi kerusakan. Penelitian ini mengembangkan model CBM multi-parameter untuk memantau kondisi pompa sentrifugal pada sistem distribusi air bersih. Parameter yang diamati mencakup getaran, suhu, dan tekanan, yang dikumpulkan secara berkala dari empat unit pompa. Pengukuran dilakukan menggunakan vibration meter, infrared thermometer, dan manometer. Data dianalisis untuk mendeteksi tren degradasi dan anomali operasional. Hasil penelitian menunjukkan bahwa suhu dan tekanan pada beberapa pompa mengalami fluktuasi, sedangkan nilai getaran tetap berada dalam ambang batas aman. Pompa dengan suhu dan tekanan tidak stabil berpotensi mengalami degradasi performa yang lebih cepat. Penerapan CBM memungkinkan deteksi dini terhadap potensi kegagalan, sehingga dapat mengurangi risiko downtime dan meningkatkan efisiensi pemeliharaan. Studi ini menekankan pentingnya pemantauan berbasis kondisi dalam menjaga keandalan sistem distribusi air bersih, terutama di lingkungan pendidikan yang memiliki keterbatasan anggaran pemeliharaan. Penelitian ini merekomendasikan pemantauan jangka panjang serta analisis lebih lanjut terhadap hubungan antara performa pompa dan konsumsi energi.

Abstract

The conventional agricultural system that is applied tends to use chemicals such as pesticides, on the one hand, providing various positive impacts, including increasing productivity quickly, meeting food needs efficiently, and helping food insecurity as often occurs in India. Sustainable agricultural systems are aimed at reducing environmental damage, maintaining agricultural productivity, increasing farmers' income and improving the stability and quality of life of rural communities. Three big indicators that can be seen are that the environment is sustainable, the economy is improving (prosperous), and it is socially accepted by the farming community. Other negative impacts on conventional agricultural systems include decreasing soil quality, giving rise to new pests and diseases, environmentally friendly microorganisms becoming extinct, toxic chemicals threatening the condition of the biosphere in the food chain. The concept of organic farming that is applied ideally is based on optimal, balanced, efficient management of land, water and land, so that existing biodiversity is one of the external efforts to provide a positive impact. In writing this literature review, the sections that will be discussed include the application of conventional agricultural systems that occur in India, suggestions and improvements that can be implemented based on potential such as modeling greenhouse gas emissions from agriculture, GHG (Greenhouse Gas) mitigation from agriculture, absorption of element C in agricultural soil, conservation agriculture, reducing nitrous oxide emissions, economic implications of greenhouse gas mitigation, and the use of butterfly pea flower kombucha in agricultural aspects
