Bioactive compounds and antioxidant capacities of “Phulae” and “Nanglae” pineapple (Ananas comosus L. Merr) which are important geographical indications of Chiang Rai, Thailand were investigated. Two pineapple varieties were collected at 20-40 % yellow peel colour. Total soluble solids (TSS), titratable acidity (TA), total polyphenols, β-carotene, vitamin C and antioxidant capacity (ferric redu...

Teluk Kendari merupakan urat nadi perekonomian penting di Kota Kendari. Sedimentasi menjadi isu utama yang dapat mempengaruhi luasan termasuk aktivitas berlangsung kawasan tersebut. tinggi ditunjukkan dari tingginya nilai Total Suspended Solid (TSS) suatu perairan, sehingga perlu dilakukan pemantauan TSS secara periodik untuk mendukung upaya penanganan sedimentasi. Penelitian ini bertujuan meng...

The chemical and biological stability of wine are very dependent on pH value, hence winemakers believe that plays a critical role in fermentation final quality. This paper optimized assessed the influence different physicochemical parameters must prepared from hot water extract leaf Broom-cluster Fig (Ficus capensis) with Saccharomyces cerevisiae, ameliorating to 22 oBrix using table sugar addi...

The aim of this study was to determine the effectiveness of natural flocculants to reduce solids and nutrient loads in dairy cow wastewater using solid-liquid separation; chitosan was used as a model. Its use efficiency and optimum application rate were determined using flushed dairy cow manure of varied strengths - 0.4%, 0.8%, 1.6%, and 3.2% total solids (TS) content. Treatments consisted of n...

In order to improve the resistance of apples stresses (abiotic stresses) during hot and dry summers enhance their productivity marketability, Anna apple trees were treated with aminoethoxyvinylglycine (AVG), 1-methlcyclopropene (1-MCP), naphthalene acetic acid (NAA), alone, or in combination, two successive seasons. All treatments significantly increased yield per tree, average fruit volume, di...

Penelitian ini bertujuan untuk menentukan konsentrasi logam berat, suhu, pH, konduktivitas listrik, total padatan terlarut (TDS) dan tersuspensi (TSS) pada sampel air muara Sungai Batang Arau. Nilai berat diukur menggunakan alat inductively coupled plasma (ICP), suhu termometer, pH meter, listrik konduktiviti TDS TSS ditentukan metode gravimerti. Dari hasil penelitian diperoleh nilai rata-rata ...

The present study was conducted on five ber (Ziziphus mauritiana Lamk) cultivars (Komethry, Pakstany, Um-sulaem, Toffahy and Peyuan) grown in Saudi Arabia during 2005 and 2006 seasons. The aim of the present study was to investigate fruit properties (fruit weight, length, diameter, shape, specific gravity, seed weight, pulp percentage, total soluble solids (TSS), acidity percentage, TSS/acid, v...

A circular gravity-phase separator using coalescing medium with cross flow was developed to remove oil and suspended solids from wastewaters. Coalescence medium in the form of inclined plates promotes rising of oil droplets through coalescence and settling of solid particles through coagulation. It exhibits 22.67% higher removal of total suspended solids (TSS) compared to separators without coa...
