Abstract

Coconut oil in West Kalimantan is still largely a traditional coconut oil because it has not gone through a refining process. To improve the quality of traditional coconut oil, the addition of activated charcoal can be used as an adsorbent so as to improve the quality of coconut oil. Activated charcoal can be made from materials that contain high carbon, one of which is a coconut shell. The purpose of this study was to determine the effect of adding activated charcoal to improving the quality of traditional coconut oil and the concentration of adding activated charcoal that produced the best characteristics of coconut oil. The research design used was a Randomized Block Design with one factor (coconut shell active charcoal concentration) 6 levels of treatment (0%, 1%, 2%, 3%, 4%, 5%) with 4 replications. The data obtained were analyzed using ANOVA (ɑ = 5%) if there was an influence followed by BNJ test (ɑ = 5%). The results showed that the addition of coconut shell activated charcoal with a concentration of 1% -5% to traditional coconut oil can significantly reduce free fatty acid levels. In addition, the addition of activated charcoal affects the sensory attributes of color and aroma to be better than the control (without the addition of activated charcoal). The best traditional coconut oil produced in this study is traditional coconut oil added with coconut shell activated charcoal with a concentration of 5% with chemical and sensory characteristics as follows: water content 0.138%, free fatty acid content 0.428%, saponification number 231, 9 mg KOH / g, color value 4,88, and aroma value 3,68.Keywords: adsorbent, activated charcoal, coconut oil, refining, coconut shell

Abstract

Syrup is an alternative processed food derived from fruits. Fruit syrup is produced from starfruit and pineapple juice formulations. This study aims to get the best quality of fruit syrup from starfruit juice extracts and pineapple. The study design used a Randomized Block Design with one treatment factor consisting of the ratio of starfruit and pineapple juice that is 3: 1; 2: 1; 1: 1; 1: 2; 1: 3 of a total of 300 mL of juice. The results showed that the more pineapple ratio added to the manufacture of fruit syrup, it can increase the pH value, vitamin C, total dissolved solids, viscosity, total sugar and sensory appearance

Abstract

Kue semprit adalah salah satu kue kering jenis biskuit berlemak dan termasuk dalam klasifikasi kue kering dengan teknik semprot. Tujuan penelitian ini untuk mengetahui kecenderungan mutu dari kue semprit dengan adanya substitusi tepung biji cempedak, serta mendapatkan substitusi terbaik dari tepung terigu dengan tepung biji cempedak berdasarkan karakteristik fisikokimia dan sensori. Penelitian dilaksanakan menggunakan Rancangan Acak Kelompok (RAK) satu faktor, yaitu substitusi tepung terigu dan tepung biji cempedak (P) yang terdiri dari 6 taraf perlakuan dengan 4 kali ulangan. Berdasarkan hasil penelitian dapat disimpulkan bahwa pemanfaatan tepung biji cempedak sebagai bahan pensubstitusi tepung terigu dalam pembuatan kue semprit berpengaruh terhadap kadar air, kadar abu, protein, dan karbohidrat, namun tidak berpengaruh terhadap kadar lemak kue semprit. Perlakuan terbaik diperoleh dari substitusi tepung terigu dengan 60% tepung biji cempedak dengan hasil uji karakteristik fisikokimia berupa kadar air 2,51%, kadar abu 1,48%, kadar lemak 30,28%, kadar protein 7,99%, dan kadar karbohidrat 57,74%.

Abstract

Solanum ferox Linn is one of the local agricultural products. Its local name is “terong asam”, the plant's shape is like eggplant but the fruit is round, orange with ripe and sour taste. The problem is that the fruit is easily damaged if left in its fresh. One of the innovations to increase the shelf life is to process it into processed dry sweetmeats. However, the amount of sugar that produces the best physicochemical characteristics of “terong asam,” dry sweetmeats is currently unknown. This study aims to obtain the concentration of sugar that produces the best physicochemical and sensory characteristics of “terong asam,” dry sweetmeats. The research design used was a randomized block design with one treatment, namely concentration of sugar, which consisted of 4 treatments and 6 replications. Analysis of physicochemical data using ANOVA (Analysis of Variance) and Honest Significant Difference (HSD) Test with a level of 5% significantly. Sensory data were analyzed by Kruskal Wallis test. Determination of the best treatment using the effectiveness index test. The results showed that the production “terong asam,” dry sweetmeats is recommended by using a 50% sugar concentration which the best sensory physicochemical characteristics of the sweets, namely water content (13.28%), pH (5.08), yield (26.49%), vitamin C (8.7mg/100g) with sensory characteristics of colour (3.17), taste (2.67), aroma (3.30), texture (3.20).
