Abstract

Telah dilakukan penelitian pemanfaatan kaolin Tatakan, Kalimantan Selatan dengan mentransformasi kaolin menjadi zeolit. Zeolit disintesis dari kaolin dengan proses hidrotermal. Sebelum dilakukan sintesis, kaolin terlebih dahulu diubah struktur berlapisnya menjadi amorf dengan proses metakaolinisasi pada temperatur 800 ºC selama 3 jam. Proses hidrotermal menggunakan autoclave dilakukan pada temperatur 100 ºC selama 24 jam dengan variasi konsentrasi NaOH yaitu 3, 5 dan 7M. Hasil analisis XRD, FTIR dan SEM menunjukkan zeolit yang terbentuk adalah zeolit LTA, sodallite dan Na-X.  Kata kunci : sintesis, kaolin, zeolit, konsentrasi NaOH

Abstract

Clean water is a fundamental requirement for human life. People depend on easy and safe access to clean water to fulfill their daily needs. Palangka Raya is the capital city of Central Kalimantan Province and is also affected by the process of moving the National Capital City (IKN) to Kalimantan. The population growth rate is increasing every year, accompanied by an increasing number of settlements in Palangka Raya. Its area is mostly peatland, so its surface water affects the well water used by many newly established settlements as a source of clean water for its citizens. In this service, the method is sampling residential healthy water, analyzing water samples, and counseling residents. Water analysis shows that healthy water is quite suitable for hygiene and sanitation purposes but not for consumption according to clean water quality standards based on Permenkes No. 32 of 2017. The results of the socialization showed an increase in the level of understanding of residents on healthy water quality. This activity is expected to help the government improve the Casadova residents' health. It is expected to increase the knowledge and awareness of residents about the proper use of well water and maintaining the quality of healthy water.

Abstract

The world's population has reached 7 billion or doubled from the previous half-century and continues to increase every year. This increase in population is directly proportional to the increase in electrical energy consumption. Electricity needs in Indonesia are mostly met by Steam Power Plants. Unfortunately, the use of coal as an energy source in Steam Power Plants can cause environmental pollution, namely the waste generated by fly ash and bottom ash. However, even though it is classified as hazardous materials, silica (SiO2) and alumina (Al2O3) content in the waste are high enough so that it can be used for the synthesis of aluminosilicate-based materials. The ash waste in this study was obtained from the Steam Power Plant in Kapuas Regency, Central Kalimantan Province which was tested according to the ASTM D93-10 standard. The composition of SiO2, Al2O3, Fe2O3, and CaO in fly ash was 56.44; 31.31; 0.51; 0.78%. The compositions of SiO2, Al2O3, Fe2O3 and CaO in the bottom ash were 66.66; 17.09; 0.31; 5.40%. Based on its composition, fly ash and bottom ash are classified as type F ash. In addition, fly ash and bottom ash have SiO2/Al2O3 ratios of 3.90 and 1.80, respectively. It can be concluded that fly ash and bottom ash has the potential to be used as basic materials for the manufacture of aluminosilicate-based materials such as geopolymers, zeolites, and others.

Abstract

Ultraviolet (UV) merupakan radiasi matahari yang masuk ke bumi sekitar 10%. Berdasarkan panjang gelombangnya, radiasi UV dikategorikan menjadi tiga jenis yaitu UV-A dengan rentang 400-320 nm dan UV-B memiliki rentang 320-280 nm, serta UVC pada rentang 100-280 nm. Radiasi sinar UV dapat memberikan beberapa manfaat bagi kehidupan. Namun, radiasi sinar UV yang berlebihan pada kulit manusia dapat menyebabkan penurunan kualitas kesehatan kulit manusia itu sendiri. Sehingga, perlu adanya penggunaan tabir surya untuk mengurangi dampak negatif dari sinar UV. Salah satu dari senyawa organik yang dapat dijadikan sebagai bahan tabir surya yaitu senyawa kumarin. Pada penelitian ini, dilakukan permodelan optimasi geometri dan spektra UV dengan menggunakan metode semi-empiris Austin Model 1 (AM1). Data spektrum UV yang dihasilkan dari permodelan menunjukkan bahwa ketiga senyawa turunan kumarin tersebut memiliki puncak absorpsi pada panjang gelombang 263 nm dan 345 nm untuk senyawa A, 266 nm, 311 nm, dan 360 nm pada senyawa B, serta 271 nm, 314 nm, dan 363 nm untuk senyawa C. Ketiga puncak serapan senyawa turunan kumarin tersebut berada pada rentang UV A, UV B, dan UV C, sehingga dapat diprediksikan bahwa ketiga senyawa tersebut dapat digunakan sebagai tabir surya anti UV-A, UV-B, dan UV-C.

Abstract

Coordination compounds are compounds consisting of a metal atom as a center surrounded by ligands, which are important in applications such as catalysts and pharmacological sensors. Salophen, as one of the organic ligands, is capable of forming complexes with various metal ions. This study uses a computational chemistry approach to model the geometry, electronic properties, and bond vibrations of compound complexes between salophen and Zn(II), Cd(II), and Hg(II) metal ions using the PM6 semiempirical method. Modeling results show that the metal ion radius affects the dihedral angle of salophen, with the largest angle occurring in the complex with Hg(II) ions, while the complex with Cd(II) ions tends to be close to planar. FTIR analysis shows that the vibrational pattern is influenced by the bond length of salophen with metal ions. In addition, the HOMO-LUMO gap energy of the three complexes is also slightly different, with the Zn-salophen complex having the smallest Egap of 0.25709 eV.

Abstract

Abundant coal reserves make this material a substitute fuel choice, especially for industry. The use of coal carries a high risk due to incomplete combustion and produces fly ash products. Fly ash cause pollution and health risks as well as environmental contamination when they are released, deposited, or leached into the ecosystem over short or long periods of time. The high content of silica and alumina in fly ash can be utilized and modified into new materials with added value. This research aims to modify the surface of fly ash using stearic acid as a hydrophobic inorganic material. Fly ash from Asam-asam Coal Power Plant was characterized by using XRD and modified by immersing in stearic acid (2,4,6, and 8%) and 98% ethanol. The result showed that the contact angle increases when fly ash is modified on the surface using stearic acid. The contact angle increases with increasing stearic acid concentration. The highest contact angle was obtained at a stearic acid concentration of 8%, and the lowest at 2% was about 112.9 and 102.2, respectively. The fly ash composition was primarily silica and alumina, which were crystalline, as confirmed by XRD. These findings provide several aspects of fly ash and its potential as a candidate material for environmental remediation and waste management.

Abstract

Sinar UV merupakan salah satu gelombang elektromagnetik yang dipancarkan oleh matahari. Paparan sinar ultraviolet berlebih dapat menyebabkan dampak buruk bagi kulit, terlebih UV A dan UV B yang memiliki kecenderungan lebih tinggi untuk menyebabkan kerusakan pada kulit. Kuersetin merupakan salah satu senyawa golongan flavonoid yang dapat mengalami modifikasi pada struktur cincin benzenanya membentuk beberapa senyawa turunan kuersetin. Modifikasi struktur cincin benzena kuersetin memberikan pengaruh pada kemampuan kuersetin dalam menyerap sinar UV. Pada penelitian ini dilakukan permodelan struktur dan spektra UV pada tiga senyawa turunan kuersetin melalui metode semi empiris untuk mengetahui sifat dan efektivitas turunan kuersetin sebagai senyawa pelindung radiasi ultraviolet (UV). Studi komputasi yang dilakukan menggunakan Austin Model 1 (AM1) yang dapat memprediksi absorbtivitas UV pada senyawa. Hasil penelitian yang telah dilakukan menunjukkan bahwa modifikasi senyawa kuersetin dengan gugus alkil (metil) pada senyawa 1, 2, dan 3 berpengaruh terhadap panjang ikatan, sudut dehedral, dan energi gap HOMO LUMO 3 senyawa turunan kuersetin tersebut. Data spektrum UV yang dihasilkan melalui pemodelan transisi elektron menunjukkan bahwa ketiga senyawa turunan kuersetin memiliki puncak absorpsi yang terletak pada wilayah UV-A. Ketiga senyawa turunan kuersetin tersebut memiliki potensi sebagai pelindung dari sinar UV-A.
