Abstract

Empty fruit bunches (EFB) are  solid wastes  produced in large quantity from palm oil industry. Thus, the wastes could cause serious problem to environment. The application of EFB as main component for composting process along with chicken dung is desirable. This research used the EFB combined with chicken dung, POME (Palm Oil Mill Effluent) and EM-4 in order to accelerate the composting process. Control’s sample was made using POME as an activator without EM-4. Quality of compost was determined according to its pH, water content and C/N ratio  at each 5 days for  30 days composting period.  The water content from the samples were determined using gravimetric method while total of N  were determined using Kjehdal method. The result showed that co-composting of EFB and chicken dung    using POME and EM-4 as the activators didn’t have significance difference  on the control’s sample with the value of P>0,05. Meanwhile, the value of pH, water and C/N ratio of composting products were respectively 7, 40-50% and 17-19 after 30 days composting period

Abstract

The demand for petroleum has increased recently due to the increase of world population, industries andtransportation. Biodiesel (fatty acids methyl esters) has become attractive because of high price of petroleum,limited recourses of crude oil, and environmental concerns. Most biodiesel is produced by transesterification oftriglycerides of refined/edible type oils using methanol and homogeneous catalyst such NaOH and KOH. The useof heterogeneous calcined CaCO3 catalyst, has advantages such as the ease of phase separation betweencatalyst and biodiesel. This paper presents factors affecting the synthesis of biodiesel from crude palm using thecalcined CaCO3 catalyst . The synthesis is carried out by two steps, the acid-catalyzed pre-esterification of free-fatty acid and followed by base-catalyzed transesterification of triglycerides. A study of optimizing the reactioncondition of the esterification followed by transesterification of crude palm oil (CPO) is performed to obtainmaximum production of biodiesel. Under conditions of catalyst calcination temperature of 9000C, reactor time of1.5 hours, catalyst dosage of 1,5%, reaction temperature of 700C and methanol/oil molar ratio of 9 : 1, the oilconversion is 74,6%. The as-synthesized biodiesel meets the requirements of Indonesian National Standard (SNI)for biodiesel.

Abstract

Dahlia is a floriculture plant with tuber that rich of inulin. Inulin is soluble in hot water and it will settle on cool temperature in alcohol. Extraction of result from 100 g dahlia tuber taken from Bukittinggi, West Sumatra is 4% inulin (w/w dahlia tuber). Inulin flour produced is white gray. Qualitative tests with Seliwanoff and Nelson-Somogyi methods shows that inulin positive contained of fructose and reducing sugar. Extracted result of inulin can be converted into levulinic acid using acid catalyst at high temperature. In this experiment, production of levulinic acid will bundle with variate temperature, reaction time and catalyst concentration of hydrochloride acid. The reaction of inulin convertion was done in ampul that burned in oven. Conversion result of 5% inulin to be levulinic acid on heating 150 o C hydrochloride acid concentration 0,1 M about 25 minutes was 12,33% (w/w inulin). On heating 170 o C hydrochloride acid concentration 0,1 M about 15 minutes is 26,25% (w/w inulin), while on heating 150 o C hydrochloride acid concentration 1 M about 15 minutes is 32,28% (w/w inulin). Experiment result showed that concentration of glucose, levulinic acid and formiat acid increase with increasing in reaction reaction temperature while fructose concentration decrease from 55,14 mg/mL to be 0,12 mg/mL. The longer time reaction and the higher concentration of catalyst hydrochloride acid, the lower concentration of glucose and fructose and the larger concentration of levulinic acid and formic acid.

Abstract

The composting process using  oil palm solid wastes (EFB),  palm oil mill effluent (POME), fern tree using effective microorganism 4 (EM 4) has been  conducted and this would facilitate  reduction of  the wastes from palm oil industry. The aim of this research was to find the best formulation using oil palm wastes, ferns, and EM 4 in producing a composted  material. The quality of compost was determined according toits pH, water content and C/N ratio at each 5 days for 30 days composting period. The water content of sample was determined using Gravimetri methode, while total-N was analyzed by Kjeldahl methode. The result indicated  that  co-composting of EFB andferns  using POME and EM-4 as the activators didn’t have  significance difference compared with that of  the composting products with the value of P>0,05. The value of pH, water and C/N ratio of composting products were respectively 7-8, 40-60% and 1314, following 30 days composting period.

Abstract

The utilization  of  Manihot esculenta  to produce  platform chemical such as    levulinic acid  (LA)    has  been  studied    in  detail to  optimize    the  LA  production. The  LA production from  Manihot esculenta  was  monitored  using    reaction times  of  the hidrolysis reaction (3-85 min.),    the reaction temperatures  (150˚C, 170˚C,  and 190˚C), and  concentrations  of sulfuric acid as the catalyst  (1%,  3%,  and 5%).  The  products obtained  were  then  characterized using  high performance  liquid  chromatography (HPLC)    to determine the contents of gl ucose,  hydroxymethylfurfural  (HMF)    and LA. The result showed that  the LA production increased with  the  rise    of temperature  and catalyst concentration, whereas the    glucose and HMF  production decreased with    the rise  of temperature and catalyst concentration. The highest  production    of LA reached approximately 50% (based  on initial concentration of biomass) at reaction temperature of 170˚C and 5% of sulfuric acid concentration for 70 minutes of reaction time.

Abstract

Mangan oksida hasil sintesis menggunakan metode sol-gel dengan perbandingan prekursor KMnO4 dan maltosa (4: 1). Karakterisasi struktur mangan oksida menggunakan difraksi sinar-X untuk menentukan struktur, tingkat kristalinitas dan tingkat kemurnian, Scanning Electron Microscopy (SEM) untuk menentukan morfologi dan ukuran partikel, dan luas permukaan dengan metode metilen biru. Hasil menunjukkan bahwa mangan oksida hasil sintesis merupakan campuran mangan oksida berongga type cryptomelane dan hausmanite, adapun karakterisasi dengan SEM menunjukkan partikel mangan oksida berbentuk seperti gumpalan-gumpalan awan dengan ukuran partikel + 1 μm dan luas permukaan 10,716 m2/g. Penelitian ini bertujuan untuk mempelajari kemampuan mangan oksida sebagai katalis pada proses oksidasi fenol. Oksidasi fenol dilakukan pada variasi suhu reaksi (300C, 400C, 500C dan 600C) dan waktu reaksi (30, 60, 90, 120, 150 dan 180 menit). Hasil optimum menunjukkan bahwa katalis mangan oksida sebanyak 0,1 g dapat mengoksidasi fenol pada konsentrasi 100 ppm sebesar 92,7% pada suhu 600C di menit ke-150. Kajian kinetik menunjukkan bahwa oksidasi fenol mengikuti orde satu dengan energi aktivasi sebesar 2,19 kJ/mol.

Abstract

Saat ini, pelepah kelapa sawit merupakan limbah pertanian yang belum dimanfaatkan secara optimal. Pada penelitian ini, limbah pelepah kelapa sawit dikonversi menjadi kompos dengan cara fermentasi. Proses pengomposan dilakukan menggunakan kombinasi bioaktivator lokal ditambah kotoran ayam yang berfungsi menyediakan nutrisi bagi bioaktivator. Bioaktivator sebagai starter yang digunakan merupakan kombinasi dari dua Isolat yaitu Pseudomonas stutzeri (LBKURCC 54 dan 59) yang disubkultur pada Nutrient Broth dan difermentasi selama 7 hari menggunakan media bibit. Substrat diinokulasi 10 % starter dari total bahan. Untuk mempelajari kemampuan bioaktivator lokal dalam mendegradasi pelepah kelapa sawit dilakukan variasi sebagai berikut: (1) sampel dengan dan tanpa starter (2) sampel dengan dan tanpa pembalikan.

Abstract

Ferns weed is a plant that is widely available in the oil palm plantation that grows as a parasite on the trunks of palm oil and will result in decreased quality of fresh fruit bunches, These ferns can be used as compost material because it contains enough nutrients.The composting process is done by adding chicken manure and effective microorganism (EM-4) as well as liquid waste palm oil mill (LCPMKS) as an activator.Analysis of compost quality is determined by the parameters water content, pH and C/N ratio for 30 days and analyzed every 5 days composting time.The results showed that the addition of EM-4 activator on kompostidak mixture gives a real difference to the control sample on the value of C / N ratio with a P value> 0.05The compost produced memliliki pH value, water content and C/N ratio, respectively for 8, 40-52% dan17-19 after 30 days of composting time.
