Abstract

Processing of palm kernels at the kernel station of the palm oil mill still has a loss of kernel oil in the bulk silo kernel. This oil can be used as a raw material for solid soap. This study aims to determine the characteristics of solid soap resulting from core oil losses in terms of physical, chemical and organoleptic parameters and to obtain the right concentration of NaOH and fragrance oil volume to produce solid soap according to SNI 06-3532-2016. This study used a completely randomized design (CRD) with 2 factors, namely the concentration of NaOH and the amount of fragrance oil. The variables observed were water content test, foam stability, free alkaline content, pH level, and organoleptic test. Solid soap characteristics are : moisture content 10.22% - 39.17%, foam stability 45.93% - 69.4%, free alkaline content 0.16% - 0.42%, pH 9 , 86 - 13,31. Panelist acceptance rates for texture 3 - 4.05, color 3.3 - 4.05, aroma 3.1 - 3, 85 and oerall 3.35 - 4, 05.Soaps made with 20% NaOH and 2 ml fragrance oil has met SNI 06-3532-2016

Abstract

This research aims to determine the performance influence of sachets on various sizes of bags and the weight of coffee to the characteristics of the brew of coffee bags. The study uses a completely random design with 2 treatment factors, the first factor of the volume of contents in the bag and the second factor of the packaging bag size. Analyzed With ANOVA dan when the effect is noticeable. It will be followed by using a DMRT at  5%. significant levels. The research at moisture and ash content is suitable for the raw material of coffee bags. Coffee Sari qualified SNI is on the treatment of the volume of 1/4 content and small bag size with a yield of 22.02% coffee juice. The results of the analysis on the missing coffee weight test were obtained the highest value found in the volume of the 1/3 content with a large bag size resulted in 2.73 grams of lost coffee weight. The lowest value is on the 1/2 content volume and the medium size is 0.17 grams. The sensory test was derived that the panelists preferred it to the size of a large bag and the appropriate volume of contents to fill the bag with a volume of 1/3.Keywords: Bag size and coffee weight, Coffee characteristics.

Abstract

Biopulping is fungal pretreatment of wood chips to reduce unused chemical composition of material in pulping. Preliminary study showed that pretreatment of Phanerochaetachrysosporium to Acacia mangium Willd can reduce lignin and improve holocellulose and cellulose content of the material. Fiber dimension recognized as other important factor for paper properties. The question is how the integrity and dimensions of the wood fiber that has been pretreated with the fungus. The objectives of present study were to know effect of pretreatment of P. chrysosporium to the integrity and dimensions of the fiber. The P. chrysosporium was cultured for 14 days in growth medium, and inoculated to wood chips 5% (w/v) and incubated for 0, 15 and 30 days. The inoculated wood chips were chipped into 1 mm x 1 mm x 20 mm and macerated using franklin solution at 60 oC for 48 hours. Forty fibers from each incubated time were analized their physical damages using a light microscope at a 400 magnification. The inoculated fibers were measured theirs dimensions. The physical damage percentage of fibers pretreated using P. chrysosporium was 0%. Length and wall thickness of the pretreated fibers were can be categorized as middle class and thin fibers, respectively.

Abstract

Antioksidan merupakan senyawa yang dapat mencegah terjadinya oksidasi. Tumbuhan merupakan sumber antioksidan alami. Salah satu tumbuhan yang memiliki kandungan antioksidan tinggi adalah bunga kecombrang (Etlingera elatior). Enkapsulasi merupakan proses pelapisan suatu zat dengan bahan lain. Proses ini dilakukan untuk melindungi senyawa aktif yang sensitif terhadap panas. Salah satu jenis matrik yang banyak diteliti untuk melindungi bahan aktif adalah maltodekstrin. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi matrik terhadap uji fisik dan kimia enkapsulasi antioksidan ekstrak kelopak bunga kecombrang dan mengetahui konsentrasi matrik terbaik pada proses enkapsulasi antioksidan ekstrak kelopak bunga kecombrang. Rancangan penelitian yang digunakan adalah Rancangan Acak Kelompok (RAK) dengan satu faktor yaitu konsentrasi matrik yang terdiri dari 5 taraf perlakuan (5%, 10%, 15%, 20%, dan 25%). Setiap perlakuan diulang sebanyak tiga kali sehingga diperoleh 15 satuan percobaan. Parameter yang diamati meliputi kadar air, warna, vitamin C, polifenol, dan aktivitas antioksidan, serta menentukan konsentrasi matrik terbaik berdasarkan hasil perhitungan efisiensi enkapsulasi antioksidan. Analisis data dilakukan dengan menggunakan uji ANOVA dan DMRT. Hasil penelitian menunjukkan bahwa konsentrasi matrik pada enkapsulasi antioksidan kelopak bunga kecombrang memberikan pengaruh yang nyata terhadap kadar air, warna, vitamin C, polifenol, dan aktivitas antioksidan. Peningkatan konsentrasi matrik menghasilkan penurunan kadar air (dari 6,67% menjadi 4,83%), warna yang lebih cerah (dari 54,41 menjadi 65,20), aktivitas antioksidan yang lebih kuat (dari 98,31 ppm menjadi 68,66 ppm), dan peningkatan vitamin C (dari 1,22 mg/100g menjadi 2,51 mg/100g) dan polifenol (dari 5,83 mg GAE/g menjadi 8,36 mg GAE/g). Berdasarkan perhitungan efisiensi enkapsulasi antioksidan, konsentrasi matriks terbaik diperoleh sebesar 25% dengan nilai efisiensi sebesar 91,67%.
