Efektifitas Penambahan Curd Kefir terhadap Mutu Sabun dan Daya Hambat Pertumbuhan Escherichia coli pada Sabun Alami Berbahan Dasar Tallow

The ban on using triclosan as an antiseptic in bath soap in various countries has given rise to new ideas to apply natural ingredients as an alternative. Curd kefir, as a natural ingredient, can be used as an alternative antiseptic. In this study, the manufacturing of tallow-based soap has been developed by adding kefir curd as an antiseptic to improve the soap's quality and inhibit the growth of Escherichia coli. The results showed no significant difference in the soap's free alkali content, saponification number, and hardness. The inhibition of the growth of Escherichia coli increased with the rise of kefir curd concentration.The ban on using triclosan as an antiseptic in bath soap in various countries has given rise to new ideas to apply natural ingredients as an alternative.

RADIO PROPAGATION MODELING OF JOS SUBURBS AT 900MHZ USING AN ADAPTIVE NEURO-FUZZY INFERENCE SYSTEM

This study investigates radio propagation modeling of the suburbs of Jos, Nigeria, at an operating frequency of 900MHz, using an Adaptive Neuro-Fuzzy Inference System (ANFIS) Technique. Path loss values computed based on received power measurements obtained from Base Transceiver Stations situated across the suburbs of the city were used to train, validate and test the ANFIS model for capacity to predict path loss. Results indicated that the ANFIS model with a Root Mean Square Error (RMSE) value of 4.74dB offers an improvement in prediction accuracy over the COST 231 Hata model, which has an RMSE value of 5.90dB

Uji Daya Simpan Inokulum dan Ketahanan Lactobacillus plantarum terhadap pH Rendah sebagai Agensia Direct Fed Microbials untuk Ternak Ruminansia

Direct Fed microbials (DFM) is a product of non-pathogenic live microorganisms that is beneficial when given to humans or livestock to improve livestock health, feed conversion efficiency and perfomance by suppressing pathogenic microorganisms in the digestive tract and influencing the balance of intestinal microbes. This study aims to provide information about the potential of Lactobacillus plantarum FNCC 0020 as a DFM agent. This study used a descriptive experimental method. Parameters observed included resistance tests to acid pH (5, 3, 2), pH 7 were also tested to determine resistance to neutral pH. The ability of Lactobacillus plantarum FNCC 0020 to survive at room temperature with different incubation times (5, 7, 10 days) were also tested to determine the storability of Lactobacillus plantarum FNCC 0020 inoculum at room temperature.. The results showed that Lactobacillus plantarum FNCC 0020 had resistance to the lowest pH (2) and also survived at neutral pH (7) with a total colony of 2.25 x 108 and .3 x 107 CFU mL-1, respectively. Lactobacillus plantarum FNCC 0020 inoculum can be stored at room temperature for up to 10 days and still has a total colony of 3.8 x 107 CFU mL-1.Direct Fed microbials (DFM) merupakan suatu produk mikroorganisme hidup non patogen yang menguntungkan jika diberikan pada manusia atau ternak untuk memperbaiki kesehatan ternak, efesiensi konversi ransum dan laju pertumbuhan dengan cara menekan mikroorganisme patogen dalam saluran pencernaan dan mempengaruhi keseimbangan mikroba usus. Penelitian ini bertujuan untuk memberikan informasi tentang potensi Lactobacillus plantarum FNCC 0020 sebagai agensia DFM. Penelitian ini mengunakan metode eksperimen secara deskriptif. Parameter yang diamati meliputi uji ketahanan terhadap pH asam ( 5, 3, 2), pH 7 juga turut diujikan untuk mengetahui ketahanan pada pH netral. Kemampuan Lactobacillus plantarum FNCC 0020 bertahan pada suhu ruang dengan lama waktu inkubasi berbeda (5, 7, 10 hari) juga diuji untuk mengetahui daya simpan inokulum Lactobacillus plantarum FNCC 0020 pada suhu ruang. Hasil penelitian menunjukkan bahwa Lactobacillus plantarum FNCC 0020 memiliki ketahanan terhadap pH terendah (2) dan masih bertahan pula pada pH netral (7) dengan total koloni 2.25 x 108, dan 1.3 x 107 CFU mL-1 secara berturut – turut. Inokulum Lactobacillus plantarum FNCC 0020 dapat disimpan pada suhu ruang hinga 10 hari masih memiliki total koloni 3,8 x 107 CFU mL-1

Weight Loss Corrosion Study of Some Metals in Acid Medium

This research was undertaken to examine the corrosion behavior of some metals in different acid solutions using weight loss technique. The magnitude of corrosion of these metals in 0.5 – 3.0 M of solutions of HCl, H2SO4, and HNO3 was studied for an exposure period of 100 minutes (at 20 minutes interval). Rate of corrosion in metals followed this order: zinc > galvanized iron > copper >, while rate of corrosion in aqueous media followed this order: HNO3 > H2SO4 > HCl. It has been obtained that concentration increase leads to increase in rate of corrosion. Further study on the corrosion kinetics has revealed that the rate of reaction of the metals increases with increase in solution concentration, while the half life decreases with increase in solution concentration
