Kasumba turate (Carthamus tinctorius Linn) or safflower is a traditional medicine used by South Sulawesians. Polyphenol compounds and antioxidant activity are active components of kasumbu turate. This component can be obtained through extraction. The goal of this study was to find the best conditions for extracting kasumba turate with high total phenol levels and strong antioxidant activity, as well as encapsulating the resulting extract. The ultrasonic assisted extraction (UAE) method was used to extract Kasumba turate with methanol, and the Responses surface Methodology method was used to optimize the extraction. Behnken Box Variations in composition solutions of 50, 60, 70, 80, and 90%, as well as time variations of 20, 30, 40, 50, and 60 minutes. A solvent ratio of was used for sample extraction 1: 1 using Methanol solvent and water, determined which is the best result of this variable, and continued by analyzing is a test analysis with Spectrophotometry, DPPH, and the best results of the variable are analyzed using Spectofotometry to see the content of flavonoid compounds in Kasumba Turate Flowers.

This study was conducted to determine the effect of the concentration ratio of Polyaluminium Choride (PAC) and Polydadmac coagulants on the coagulation and flocculation processes in river water treatment. The raw water used is raw water that is processed by IPA Taman Kota PT. XYZ namely Cengkareng Drain river water with a turbidity of 19.3 NTU and a pH of 7.22. This study uses the jar test method. The selected variables are variations in the concentration of PAC and polydadmac. The water produced from the jar test was tested for its turbidity and pH. This research was started by sampling raw water, then 1000 ml was put in each glass jar test tool. Then the flocculation process was carried out with a stirring speed of 200 rpm for 2 minutes. Followed by the coagulation process with a stirring speed of 40 rpm for 18 minutes. The process continued with sedimentation for 10 minutes. The optimum dose obtained was the combination of 20 ppm PAC and 0.4 ppm polydadmac with a turbidity value of 1.08 NTU or with a removal efficiency value of 94.40% and a pH value of 7.06.

Kalium hidroksida dibuat dari hasil elektrolisis kalium klorida (KCl). Kalium klorida diperoleh dengan cara impor dari Nanjing Jiayi Sunway Chemical Co, Ltd, China. Pabrik kalium hidroksida direncanakan akan berdiri pada tahun 2021 di Bangkalan, Madura, Jawa Timur, dengan sasaran dalam penjualan nanti adalah mengambil alih 60% pangsa pasar kalium hidroksida di dalam negeri. Untuk memenuhi kebutuhan tersebut, maka ditetapkan kapasitas produksi pabrik kalium hidroksida yang akan didirikan sebesar 15.000 ton/tahun. Kalium hidroksida terbentuk dengan reaksi elektrolisis memban pada reaktor elektrolisis. Elektrolisis sel membran menggunakan membran semipermiabel dari bahan hydrolyzed copolymer untuk memisahkan anoda dan katoda. Pada anoda KCl akan terionisasi menjadi ion K+ dan ion Cl-. Dimana ion K+ ini yang naninya akan berikatan dengan ion OH- yang merupakan hasil ionisasi H2O pada katoda. Sementara ion Cl- pada anoda akan bergabung membentuk gas klorin (Cl2) dan ion H+ pada katoda akan bergabung untuk membentuk gas hidrogen (H2). Kalium hidroksida yang keluar dari reaktor masih sangat encer sehingga perlu dipekatkan dengan double evaporator setelah itu larutan kalium hidroksida pekat yang keluar dari evaporator di kristalkan dengan Cryztalizer dan Rotary dryer agar didapatkan hasil granul kalium hidroksida. Saat ini kebutuhan pasar kalium hidroksida adalah industri kalium karbonat, industri pupuk, industri fosfat, industri kimia agro, baterai alkaline, industri tekstil dan industri sabun. Kebutuhan utilitas pada prarancangan pabrik ini antara lain, kebutuhan steam sebanyak 15.828,67 kg/jam , kebutuhan listrik sebanyak 853,155 kWh dan kebutuhan air sebanyak 418,96 m3/jam yang diperoleh dari pengolahan air sungai.

Chicken eggshells, commonly discarded as household and industrial waste, present a valuable opportunity for sustainable use due to their abundant quantity. This study explores the potential of utilizing chicken eggshells as a natural protein source to create eco-friendly skincare products, particularly peel-off gel masks, which can combat free radicals and enhance skin elasticity and moisture. The research focused on determining the optimal conditions for protein extraction from chicken eggshells using acetic acid solvent and varying extraction times. Response Surface Methodology (RSM) was employed to optimize these conditions. The protein extraction process involved testing the extracted protein for biuret reaction using spectrophotometry, determining protein content with Ultra Performance Liquid Chromatography (UPLC), and evaluating the physical properties of the resulting peel-off gel mask. The results indicated that both solvent concentration and extraction time significantly impact the yield of protein. The optimal conditions were found to be an acetic acid concentration of 0.5 M and an extraction time of 24 hours, which produced a yield of 5.064%. The RSM model validation showed a p-value 0.05, a desirability index of 0.887, and a predicted yield of 3.080%, with a deviation of 1.98% from the actual yield. These findings suggest that the model is accurate and reliable for further development of the peel-off gel mask. This approach not only provides a sustainable use for eggshell waste but also contributes to the development of high-quality, natural skincare products.
