Abstract

Palm oil contains carotenoid about 500-700 ppm.  Epidemiology study showed that carotenoids are beneficial for health, but most of carotenoids are destructed and loss during purification of palm oil, so need to be modified to minimize the loss and destruction of carotenoids.  One of the methods was to use NaOH to neutralize free fatty acid after degumming step.  The aim of this research was to determine optimum condition of deacidification process of palm oil to minimize the destruction of carotenoids.  This research used Central Composite Design (CCD).  Response surface model was applied to see influence of treatment to rendemen, free fatty acid and carotenoids contents of neutralized palm oil (NPO) with three variables of temperature, time, and consentration of NaOH.  This research showed the optimum condition of deacidification process of palm oil to minimize the destruction of carotenoids, i.e. temperature of 59oC, time 25 minutes, and NaOH 11.1% (16oBe).  In this condition the content of  NPO was 95%, with 0.16% of free fatty acid  and total carotenoids of 390 ppm.     Key words: palm oil, deacidification, carotenoid

Abstract

Deacidification is one of the steps in palm oil refining process which aims to separate free fatty acids formed during post-harvest handling. It is carried out using alkali solution such as NaOH (sodium hydroxide). Carotenoids in palm oil are affected by this step. Therefore, deacidification has to be controlled to minimize the destruction of carotenoids during processing. The objective of this research was to improve deacidification process in pilot plant scale so that the process can produce lower level of free fatty acids (FFA) and higher recovery of carotene in high yield neutralized red palm oil (NRPO). Characterization of physical and chemical properties of crude palm oil (CPO) such as moisture content, FFA and carotene contents, saponification number, iodine value, peroxide value, and color were determined before processing. Degumming was performed before deacidification process. The 17.5% excess of NaOH was obtained from the pilot plant scale deacidification trial. The optimization of deacidification time and temperature was carried out by using central composite design (CCD). Response surface method (RSM) was used to observe the influence of treatments on the FFA level reduction, carotene recovery, and NRPO yield. The result showed that the optimum deacidification condition was at 61 ± 2°C in 26 minutes, and at the 16°Be NaOH strength with 17.5% excess of NaOH. In this optimum condition, the process achieved 96.35% of FFA reduction, 87.30% of carotene recovery, and 90.16% of NRPO yield.

Abstract

Agile Unified Process (AUP) has been known as a suitable methodology for projects of software development of small to medium level. This methodology focuses on rapid iteration, release relatively small and often as possible, able to handle the changing needs of users, and involve users in the process of software development. However, little is known that the AUP can be effectively used for the requarement of the system needs less clear and less complete. This study reveals how AUP is a software development methodology that is most suitable for the needs of the system. At the beginning of the software development, it is very difficult for the client to specify what he needs. However, because the client is actively involved during the development of software, it can slowly improve the requarements of the system with the help of the development team. Phase in the AUP can be accurately followed and proved to be very useful and suitable for the requarements which less complete. The resulting software was successfully tested with the actual transaction. Design on a complete structured system while implementing only limited to the module and report only relates to the activities of service revenues. With the construction of this system expected revenue cycle services that exist in the company.Keywords: AUP, Accounting Information Systems, Revenue Cycle Services

Abstract

Monoasilgliserol (MAG) dari asam laurat merupakan salah satu produk turunan dari minyak nabati yang memiliki keistimewaan, berfungsi sehagai emulsifier, pengawet pangan, sanitizer, dan food supplement untuk meningkatkan imunitas tubuh. Penelitian ini bertujuan mencari kondisi optimum pembuatan monoasilgliserol dengan parameter komposisi MAG melaiui proses esterifikasi menggunakan enzim lipase imobil sebagai katalis. Metode esterifikasi enzirnatis kontinyu dilakukan pada reaktor packed bed sirkulasi. Rancangan percobaan optimasi pada penelitian ini menggunakan Central Composite Design dari Response Surface Methods (RSM). Suhu dan waktu reaksi merupakan faktor percobaan penelitian ini. Kondisi reaksi esterifikasi enzimatis kontinyu rnenggunakan rasio gliserol/asam lemak (5:1); rasio pelarut/substrat 8,8:1 dan residence time 23,57 menit. Hasil reaksi esterifikasi menggunakan RSM menunjukkan persamaan kuadrat optimasi MAG adalah Y= - 61,700 + 6,088 x1+3,259 x2 - 0,065 x12 + 0,017 x1x2 - 1,792 x22 dan menghasilkan MAG maksimum pada suhu dan waktu reaksi optimum 46,92°C (47±0,5)°C and 1,1 jam. Hasil validasi reaksi esterifikasi sebanyak lima kali ulangan menggunakan enzim lipase pada kondisi di atas menghasilkan rendemen 81,09±2,99% dengan komposisi MAG 83,15±3,51%. Koefisien keragaman untuk validasi rendemen dan komposisi MAG yaitu 3,69 and 4,25%. MAG memiliki sifat fisikokimia: bilangan asam 1,78±008%, bilangan peroksida 0,49±0,14 meq O2/kg MAG, kadar gliserol bebas 0,26%, dan memiliki kisaran titik leleh 53-53,5°C. Synthesis Optimization of Monoacylglyserol by Enzimatic Esterification.Monoacyglycerol (MAG) from lauric acid is a superior product derived from vegetable oil, which can be used as emulsifier, food preservative, sanitizer, and food supplement for increased human immunity. The aim of this research was to obtain the optimum conditions for monoacylglycerol synthesis based on MAG content using commercialized lipase. The Central Composite Design of Response Surface Methods (RSM) was used to arrange the experiments. Temperature and reaction time were the two variables investigated in the present study. Continuous enzymatic esterification was conducted in a circulated packed bed reactor with glycerol/oil molar ratio 5: I, solvent/substrate ratio 8.8:1 (wt/wt) and residence time 23.57 minute. The result showed that the quadratic equation for synthesis optimization of MAG was Y= - 61,700 + 6,088 x1+3,259 x2 - 0,065 x12 + 0,017 x1x2 - 1,792 x22 which produced maximum MAG at an optimum temperature of 46.92°C (47±0.5) °C and reaction time for 1,1 hour. Using the optimized conditions, lipase esterification, which was repeated five times, produced 81.09±2.99% yield with MAG content of 83.15±3.51%. Coefficients of variance for validation of the yield and MAG content were 3.69 and 4.25%, respectively. The MAG synthesized had the following physicochemical properties: acid value 1.78±008%, peroxide value 0.49±0.14 meq O2/kg MAG, free glycerol content 0.26%, and melting point 53-53.5°C

Abstract

This study investigates factors in the quality of local government financial reports, extending a previous study using five exogenous variables, namely commitment of management, human resources competencies, effectiveness of the internal auditor, quality of accounting system and the follow-up of audit findings from the Supreme Auditor (BPK). The research data population comprised 50 Spending Units in the area of Semarang local government. The data was collected by distributing questionnaires to all Spending Units, of whom 49 responded to questionnaires within the prescribed time. Partial Least Square (PLS) technique was used to analyze data processed using Smart PLS 3.0. The results show that the quality of the accounting system and follow-up the audit findings from the BPK have positive and significant impacts on the quality of local government financial reports. Other variables such as the commitment of management, human resources competencies and effectiveness of the internal auditor do not significantly affect the quality of local government financial reports.   Abstrak Penelitian ini bertujuan untuk menganalisis faktor-faktor yang mempengaruhi kualitas laporan keuangan pemerintah daerah.
