(Drying Analysis of Sliced Spring Onions) Alamsyah, Rizal; Mahdar, Putiati; Mustika, Yang Dewi
Warta Industri Hasil Pertanian Vol 11, No 1-2 (1994)
Publisher : Balai Besar Industri Agro

The study was desiged to investigate drying characteristics of sliced spring onions (Allium porrum L.) using experimental dryer. The drying experiments were employed with fresh and blanched spring onions based on thin layer drying. The drying experiments were conducted using different drying temperature (46C,52C,and 62C),drying air velocity (3,5 m/s and 4,5 m/s)as well as the size of materrials (0.25 cm x 0.25 cm and 0.5 x 0.5 cm). The drying characteristics obtained were presented as curves i.e. the descrease of moisture content versus time, and drying rate versus moisture content.The drying rates of fresh spring onions were generally higher than those of blanched spring onions.

Rolling oil is one kind of the lubricants which is used for metal working especially for cold rolling mill (CRM), roll collant, roll oil and pickle oil.Mostly, lubricat based rolling oil was derived from mineral or synthetic oil where its source has been depleted. Castor oil has some advantages to be employed for lubricants or rolling oil based materials since it has high load wear index lubricity, and viscosity as well as low pour point. This research was aimed at investigating the production of rolling oil using castor oil with oxidation treatment. Chitosan was also used to know its effect on rolling oil characteristics. The method of rolling oil production was designed y adding NaHSO4 as catalyst into castor oil, dehydrating of castor oil at 200 C during three hour, cooling of castor oil at room temperature, dissolving buthylated hydroxy toluene (BHT), dehydrating oil (oxidation) at 100 C during 8 hours, addition of 1 %, 3 % and 5 % of chitosan solution into oil, and dissolving O-fenilfenol into oil with oxidation treatment showed better result in term of acid number, iodine number, viscosity, and density. The best result of experiments was showed for the oxidixed rolling oil with dehydrated treatment with 5 % chitosan aolution which has acid value 1,1 mg KOH/gr oil, iodine number 59,3 gr iod/100 gr oil, saponification value 196,9 mg KOH/g oil, viscisity 180, 6 cps, density 0,97 gr/ml. In coclusion higher chitosan concentration resulted lower acid and saponification value. On the Other hand higher chitosan concentration affected higher iodine number and viscosity.

(Production Biodiesel of Used Cooking Oil by Using Palm Sugar Bunches Ash as Catalyst) Alamsyah, Rizal; Hawani Lubis, Enny; Heryani, Susi

Research on production of used cooking oil by using palm sugar bunches ash as catalyst has been conducted. This research was aimed at investigating to the variation of transesterification time (2,3 and 4 hours) by adding 5% palm sugar bunches ash catalyst. The result of transesterification show the use of palm sugar bunches which is uncomposted give better result than the used of composted in tern of kinematic viscosity value. For other parameter (acid value, glycerol total contain, ester value) using either composted or non composted give biodiesel that meet biodiesel requirement No. 04-7182-2006. Based on the research, it could be concluded that 2 hours transesterifikation using non composted catalyst give biodiesel requirement whit yield of metil ester 87,90% and acid value 0,73 mg KOH/g, kinematic viscosity 2,39 cSt, glycerol total contain 0,128 (%b/b) and aster content 98,72 (%b/b). While a composted catalyst give kinematic viscosity value between 1,69 - 1,98, that is not meet biodiesel requirement (2,3 - 6,0 cSt).

(Additional Effects of Chitosan and Turmric Solution to Soup Noodle Quality) Alamsyah, Rizal; Susanti, Irma; Nurhayati, Lilis

Soup noodle is one kind of the noodle that prevered by a lot of Indonesian people. Sunch noodle has short shelf life due to easiness for deterioration. The prolong the shelf life of this noodle, chemical ingredients are commonly used as formalin solution taht is harmful for humankind health. There are some alternatives of natural preservatities such chitosan and turmeric that can be treated to substitute the chemical preservatities. This study was devoted to investigate the effect of natural preservatives chitosan and turmeric sollution addition on soup noodle quality. The experiments use soup noodle which immerses into: 15ppm, 45ppm and 75 ppm of chitosan solution. 1% and 1.5% of turmeric solution. The analysis of quality of soup noodle were conducted in term of visual deterorietion, pH, moinsture content, totalized titration acid, total plate count (TPC), and opganoleptic tests. The experiment showed that soup noodle which were immersed into 15 ppm, 45 ppm, and 75 ppm of chitosan solution as well as into 1% and 1.5% of tumeric solution keep noodle good only for less then 24 hours. The soup noodle in the next 24 hours has a bad smell, acid condition, and TFC value is not eligible to the SNI standard that 1.0 x 10-6 coloni/g.

(Design and Technical Testing for centrifuge for degumming and Vacuum Deodorizer for Palm kernel Oil (PKO)) Alamsyah, Rizal; -, Rienoviar; Mitha Mala, Dheni

Deodorizing and reaction time of degumming are some of the most important factors that can affect the quality refined vegetable oils or its derivatives. The results of unit operations in doedorizing and degumming give low viability of product especially produced by vegetable oils smallholder industry in Indonesia. To increase quality of those and income producer there is a need to enhance process by introducing appropriate equipments. This study was devoted in designing and testing centrifuge for degumming of crude vegetable oils (Palm kernel oil) and vacuum deodorizer using jet pump for refining oils. The maximum capacity of sentifuge constructed is 12 liters and it was equipped with four container and 1 horse power of induction motor. The performance test of centrifuge showed reaction time for degumming was two hours with maximum impurities or gums (7%). This reaction time is shorter than those of conventional degumming process using settling tank e.g all night reaction time. Deodorizer reactor has capacity of 40 liters oil processed, and it is generated with 1,1 hp of induction motor. steam from small boiler unit was introduced to the doedorized tank to reduces impurities and free fatty acid (FFA). The reactor was equipped with metal heater element of 5000 watt which immersed in silicon oil as heating medium and it was covered by insulator. The reaction temperature of deodorizing process was 160 degree celcius. Palm kernel oil quality processed by vacuum deodorizer tested e.g. free fatty acid (FFA) was 0,03%, peroxide number was 3,03 meq/kg, moisture content was 0,94%,anisidin number was 3,97, and color were yellow and red (0,4 and 7). It means that those results of refined palm kernel oil caracteristics meet the standard required.
