Abstract

Nanopartikel memiliki ukuran yang sangat kecil yaitu 1-100 nm nanopartikel dengan mudah keluar dan masuk ke dalam sel tubuh tanpa menggangu kerja sel sebab ukuran nanopartikel sangat kecil. Nanopartikel biasanya dibuat dengan metode fotokimia, elektrokimia, radiolytic, sonolytic dan bioreduksi menggunakan produk alami. Aging ialah pergantian manusia yang disebabkan oleh aspek umur, psikologi, serta sosial. Pada biasanya aging dimaksud bagaikan pergantian raga manusia. Pergantian raga bisa dihambat dengan salah satunya memakai anti aging semacam obat ataupun kosmetik. Pada proses ini diambil pada cream dengan bahan emulsi yaitu campuran dua cairan yang sulit menyatu seperti air dan minyak. Emulsi yang diinginkan adalah memiliki sifat tidak berubah menjadi lapisan-lapisan, tidak berubah warna, dan tidak berubah konsistensinya selama penyimpanan untuk emulsi yang tidak stabil dapat disebabkan oleh beberapa hal antara lain komposisi bahan yang tidak tepat, tidak sesuainya rasio antara fase terdispersi dan fase pendispersi. Pada proses nanopartikel aktivitas antiaging pada crem menggunakan bahan emulsi ini jika ditambah menggunakan nanopartikel silver maka cream ini akan menjadi lebih baik karena memiliki konduktivitas listrik yang besar sebagai pembunuh bakteri sehingga bisa mencegah kotoran maupun kekerutan pada kulit. Tujuan penelitian ini untuk mengetahui keefektifan bahan emulsi jika digunakan pada cream dan nanopartikel silver. Metode penelitian yang digunakan adalah studi literatur karena mengolah data dari kumpulan artikel.

Abstract

This study investigated the flow and sedimentation patterns at a series of check dams on the Kuranji River. A physical model was built in the laboratory at a specific scale to simulate field conditions. The models were built using an approach to existing conditions with a dam height scale of 1:125 while the check dam spacing was 1:300 while the field condition spacing between check dams of scenario 1 (89.00 cm), scenario 2 (94.00 cm), scenario 3 (200 cm). All models were conducted in a 40 x 40 cm rectangular open channel in the laboratory of Fluid Mechanics and Hydraulics, Faculty of Engineering, Andalas University, Padang. Sediment material was used from the Kuranji Trunk. Furthermore, each experiment with variations in flow discharge was observed and measured the sediment distribution pattern before and after the check dam building. From the test results, it was found that the sediment balanced condition ranged from 10-19 minutes after the water came out of the dainhole. Sediment distribution patterns are influenced by two main factors, namely the distance between check dams and flow discharge. The use of too far a distance results in sediment having a greater chance of moving away downstream, on the other hand, with a close distance between check dams, the sediment distribution moves not too far. Discharge variations affect the scouring depth. The greater the flow discharge, the greater the energy to scour and carry the greater sediment.

Abstract

This study compares evapotranspiration (ETo) values obtained from direct field observations with estimates from empirical models at different elevation. The empirical models used are Modified Penman, Penman-Monteith, Blaney-Criddle, Hargreaves, and Radiation. This research was conducted in the Batang Kuranji Watershed, specifically in Pauh Subdistrict (174 m above sea level) and Nanggalo Subdistrict (18 m above sea level), from August 6th to August 31st, 2023. Daily temperature, humidity, wind speed, and solar radiation data, collected using Thermo-Pro devices and from relevant agencies, were used as input for the empirical models. Three field experiments were carried out in the form of: evaporation plots, evapotranspiration plots without infiltration influence, and evapotranspiration plots with infiltration influence. Furthermore, the observed ETo values in the field were 90.67 mm/month in Nanggalo and 90.00 mm/month in Pauh. The empirical models produced estimates comparable to field observations. Analysis of the coefficient of determination (R²) revealed that the Modified Penman empirical model was the most suitable with field experiments and showed a very strong relationship (R² = 0.96). The results of this study can be used as a basis for managing rice irrigation water and developing better ETo prediction models, especially in the Batang Kuranji Watershed. The authors identify areas needing further research to enable the model's use for calculating evaporation across an entire growing season.

Abstract

Indonesia has high rainfall, which often causes flooding. Large volumes of rainwater cause sediment in river channels to move from upstream to downstream. The shape of rivers in Indonesia tends to bend, so the researcher conducted a study of the turning channel using a check dam structure with three placement conditions, namely before the bend, in the middle of the bend, and after the bend. This research was conducted at the Fluid Mechanics and Hydraulics Laboratory, Department of Civil Engineering, Faculty of Engineering, Universitas Andalas, Padang. This study aims to determine the impact of sediment on erosion caused by the placement of check dams on river bends and to determine the distribution of sediment due to changes in the position of Check Dam buildings on river bends. A 12.8 m long channel, made of 5 mm acrylic, with a cross section of 0.4 m x 0.4 m and a bend angle of 120o, was used in the experiment. Researchers measured flood discharge and sediment distribution for each of the three check dam positions. The study showed that the sediment distribution varied significantly depending on the location of the check dam. The researchers observed that the most balanced sediment distribution, with relatively equal deposition on the inner and outer sides of the bend, occurred when the check dam was placed after the bend. Based on these findings, they recommend placing check dams after bends in meandering rivers to minimize erosion and promote a more balanced sediment distribution.

Abstract

The subject of Chemistry is still relatively unfamiliar among junior high school students because it is still part of the broader Science subject taught at that level. This is also the case at SMPN 28 Bengkulu Utara, where students are still unfamiliar with chemistry. To introduce chemistry and create a positive impression of the subject among students at SMPN 28 Bengkulu Utara, an outreach activity was conducted focusing on interesting chemical phenomena — in this case, the phenomenon of quantum fluorescence.During the activity, explanations were given about the meaning of fluorescence, the causes behind it, and its applications in everyday life. The outreach activity also included demonstrations of the fluorescence phenomenon. Participants engaged in the event enthusiastically, as seen through the students' active participation. This activity is expected to help participants become more familiar with chemistry, a subject that has long been considered difficult, intimidating, and abstract.
