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

Natural ingredients are the people's choice and are a healthy lifestyle in consuming food. One of the servings of functional drinks from natural ingredients is by effervescent tablets. The most natural ingredients used as the main ingredients of effervescent tablets are fruits, rhizomes, rind, leaves, and seeds. The most active compounds found in effervescent tablets from natural ingredients are antioxidant compounds (phenolic, flavonoids, tannins, saponins, and anthocyanins), vitamins (A, B1, B2, C, and D), and minerals (potassium, sodium, iron, and magnesium). The method most widely used to produce effervescent tablets is the wet granulation method. Other methods used are the dry granulation method and direct compression. The formulation of effervescent tablets consists of acid, base, binder, lubricant, filler, and sweetener components. The most widely used formulations of natural effervescent tablets are citric acid, sodium bicarbonate as a base, polyvinyl polydone (PVP) as a binder, PEG 6000 as a lubricant, lactose as a filler, and aspartic acid as a sweetener. The production of effervescent tablets from natural ingredients is the development of ways to consume functional drinks that are more practical and beneficial to health.

Abstract

Sago (Metroxylon sagu Rottb.) is a potentially starch source crop. However, in West Kalimantan the use of sago is still limited. There is lack information about sago starch characteristics in relation to growth stages of the palm. Therefore, this study was aimed to observe the characteristics of sago starch extracted from the trunk at variatious growth stages. Sago trunks were taken from Sui Bemban and Sui Ambawang villages, Kubu Raya regency, West Kalimantan. They were classified into four different physiological growth stages, namely dewasa (9 yr), jantung (10 yr), rusa (11 yr), and bunga (12 yr old). The starch was extracted in laboratory and then dried at 50 °C. Dried sago starches were analyzed for their chemical compositions (moisture, fat, protein, ash, carbohydrate, fibre, and amylose contents), physical cha- racteristics (colour and the granule form), functional characteristics (water absorpsion, oil absorpsion, swelling power, and solubility). Pasting properties were  characterized by Brabender amylograhpy. Results indicated that chemical composition and physical characteristics of the sago starches extracted from 9-12 year-old trunks were not signifi- cantly differrent. The highest rendement obtained from 10 – 11 year-old trunks. Amylose content was 41.8 % which was categorized as high. Functional characteristics as shown by the amylograph revealed that sago starch has type-C curve. Starch extracted from 9 yr old trunk gave the highest paste viscosity which was the most suitable for for use in product that needs a strong gelling property.ABSTRAKSagu (Metroxylon sagu Rottb.) sangat potensial sebagai sumber pati, namun di Kalimantan Barat pemanfaatan sagu sebagai sumber pati masih terbatas. Belum ada informasi mengenai hubungan tahap pertumbuhan dengan sifat-sifat pati sagu yang dihasilkan. Penelitian ini bertujuan untuk mengetahui karakteristik pati sagu pada beberapa tahap pertumbuhan. Tanaman sagu diperoleh dari Desa Sui Bemban dan Sui Ambawang Kecamatan Kubu Kabupaten Kubu Raya Kali- mantan Barat. Tanaman dikelompokkan menjadi empat fase yaitu dewasa (9 tahun), jantung (10 tahun), rusa (11 tahun), dan bunga (12 tahun). Pati sagu diekstrak di laboratorium kemudian dikeringkan pada suhu 50 °C. Pati kering dianalisa komposisi kimia (kadar air, lemak, protein, kadar abu, karbohidrat, serat kasar, dan amilosa), sifat fisik (warna dan ben- tuk granula), sifat fungsional (daya serap air, daya serap minyak, swelling power, dan solubility). Sifat amilografi dinali- sis dengan Brabender amylograhpy. Hasil penelitian menunjukkan bahwa sifat kimia dan fisik pati sagu yang diekstrak dari batang sagu umur 9-12 tahun tidak berbeda nyata. Batang sagu berumur 10-11 tahun memberi rendemen tertinggi. Kadar amilosa mencapai 41,8 %. Kurva amilografi menunjukkan bahwa pati sagu mempunyai kurva amilogram tipe-C.

Abstract

Traditional coconut oil is coconut oil that is produced for generations in a simple way. This coconut oil cannot last long without purifying. This oil is produced by heating so that the quality of the oil decreases. Improving the quality of thisoil can be done by adding extract of ethanol pandanus fragrant which is easily obtained and contains natural antioxidants. This study aims to determine the characteristics of traditional coconut oil after the addition of ethanolic extract of pandanus fragrant leaves. The study was conducted following a randomized block design (RBD) of one factor, namely the concentration of ethanol extract of pandanus leaves consisting of 6 levels of treatment, namely p1 = 0,00%, p2 = 0.02%, p3 = 0.04%, p4 = 0.06%, p5 = 0.08%, and p6 = 0.10% , with 4 replications.  Data were analyzed by ANOVA test and further tests using BNJ test with a level of 5%. The results showed that the best treatment was obtained at the ethanol extract concentration of 0.10% pandanus fragrant leaves that produce coconut oil with a water content of 0.128%, free fatty acid content of 0.489%, and a saponification rate of 229.22 mg KOH/g of oil. The highest descriptive sensory characteristics of traditional coconut oil are yellowish green (4.48) and slightly pandanus (3.20)

Abstract

The aims of this research is to determine the powder properties of aloe vera powder in different amount of cassava maltodextrin addition. The total soluble solid in aloe vera extract before spray drying was adjusted to the total soluble solid as 20%, 25%, and 30% (w/v) by adding the appropriate amount of cassava maltodextrin as carrier agents. The results showed that all aloe vera powder has the water activity in the range of safe water activity for dried food (0.32-0.38). The highest cassava maltodextrin added produce aloe vera powder with the lowest water content (4.49%). The addition of cassava maltodextrin increased brightness, reduced the water content, decreased the cohesiveness between powder particles and increased the flowability of the aloe vera powder. More of cassava maltodextrin addition caused a decrease in solubility and wettability time on aloe vera powder. The aloe vera powder particle had a round shape and uniform size. The higher cassava maltodextrin addition made a larger size of aloe vera powder particle.
