Abstract

Medicinal plants ant nests or simbagh utak (Hydnophytum formicarum) are found in the Bengkulu area south of Bengkulu province. Simbagh utak tubers (H. formicarum) can empirically treat headaches, bruises and aches. H. formicarum also has cytotoxic, antioxidant and antibacterial activity. The purpose of this study was to determine the antidiabetic activity of the ethanolic extract of the medicinal plant simbagh utak (H. formicarum) against alloxan-induced mice, and Phytochemical Test to determine the content of secondary metabolites contained in the extract. The extract was obtained by maceration by soaking simbagh utak powder (H. formicarum) with 96% ethanol as solvent. The solvent contained in the ethanolic extract of simbagh utak (H. formicarum) was evaporated using a rotary evaporator to obtain ethanolic extract of simbagh utak (H. formicarum). Furthermore, the ethanolic extract of simbagh utak (H. formicarum) was tested on mice that had been induced by alloxan. The results showed that after the ANOVA and T-student statistical tests were carried out, it could be stated that the tuber extract of the Simbagh Utak (H. formicarum) plant was seen to be very significant in reducing blood sugar levels of male mice (Mus musculus) that had been induced by alloxan at a dose of 0.7056 g. /kg BW, and tuber extract of H. formicarum contained flavonoid and phenolic compounds. Flavonoid and phenolic compounds can act as free radical scavengers.

Abstract

Red Palm Oil Olein (RPOO), obtained from Crude Palm Oil (CPO) processing, can be a potential source of provitamin A due to its high carotene. Water degumming and Alkali refining are alternative methods that are not widely used to remove gum and Free Fatty Acids (FFA) in making RPOO with relatively low heating temperatures. This study aims to determine the effect of increasing the amount of NaOH during neutralization on RPOO yield, FFA levels, β-carotene content, vitamin A, and preference level for RPOO. This study used Complete Randomized Design (CRD) with one treatment factor, namely variations in the addition of the amount of NaOH. The results showed that the variation of the addition of NaOH had a significant effect on decreasing FFA RPOO to range from 0.24 to 0.07. The content of β-carotene produced ranges from (635.87 to 645.54 ppm) and the content of provitamin A ranges from (105.97 to 107.59 μgRE). In addition, the RPOO yield decreased with an increase in NaOH use, ranging from (53.24 to 42.26%). Organoleptic tests showed that adding NaOH significantly affects the level of liking for the color and aroma of RPOO. Increasing the use of NaOH in alkaline refining could produce RPOO with good quality, but at the same time, it could reduce the yield of RPOO produced.

Abstract

Fisheries products in Bengkulu Province are still not to be classified well, so it may be considered not necessary to develop the discourse of product quality assurance. Regardless, the demands of globalization require each manufacturer to think ahead about the quality of the product "deserves" to be marketed, both in terms of the beneficial, characteristic, and image. Consumers have ample opportunity to get a product that is "inappropriate" according to his preference, one of which is through the use of brand equity as a guarantee of product quality as measured by the consumer response to price and product. The purposes of this study are: (1) to explain the relationship between the beneficial variables, characteristic, and the image of the brand equity variables, and (2) to analyze consumer response to the presence of the brand. From the results of this study also noted that the level of consumer preferences towards brand used by trader fresh fish is high in the city of Bengkulu. Assessment is based on expediency consumer brand presence (beneficial), the specific features that exist on the brand/merchant customer fresh sea fish (characteristic), and the picture attached to the brand (image). Based on the results of the Pearson test is known that the beneficial variables and the use of brand image on fresh fish merchant in the city of Bengkulu has a positive relationship to brand equity inherent in the product. Furthermore, it’s also obtained information that the consumer response to the presence of a brand that is used by trader fresh fish in the city of Bengkulu as a guarantee of quality is very good.

Abstract

Dewasa ini, nanopartikel mendapatkan perhatian istimewa di kalangan para peneliti termasuk pemerhati lingkungan karena nanopartikel memiliki luas permukaan yang sangat besar sehingga bisa dimanfaatkan lebih lanjut untuk berbagai keperluan. Penelitian ini bertujuan untuk membuat nanopartikel perak secara biosintesis menggunakan ekstrak buah anggur beserta aplikasinya sebagai pereaksi dalam mendeteksi logam berat berbahaya, khususnya merkuri (II). Buah anggur diekstraksi menggunakan air pada suhu 80°C. Setelah dicampur dengan prekursor perak nitrat, reaksi pembentukan nanopartikel perak dipercepat dengan memanfaatkan sinar matahari sebagai energi panas alami. Nanopartikel perak yang terbentuk memiliki puncak absorbansi pada panjang gelombang maksimum 420 nm, dan selektif terhadap ion merkuri (II), yang ditandai dengan berubahnya warna nanopartikel perak tersebut dari coklat kekuningan menjadi bening. Selanjutnya, kamera digital dimanfaatkan untuk menganalisis konsentrasi ion merkuri di dalam sampel. Keakuratan metode citra digital ditentukan dengan membandingkan hasil pengukurannya terhadap metode Spektrofotometri UV-Vis. Secara umum, metode citra digital dengan nanopartikel perak sebagai reagen deteksi ion merkuri dapat digunakan dengan kinerja mumpuni. Konsentrasi ion Hg (II) dari sampel lingkungan yang dianalisis menggunakan metode yang dikembangkan ini berada di bawah ambang batas yang diperbolehkan oleh Permenkes RI No. 492 tahun 2010, sehingga air lingkungan yang dianalisis masih layak dipergunakan untuk kebutuhan rumah tangga.
