Abstract

The need for plastic corresponds with the annual rise in population. Meanwhile, plastic waste that is improperly managed can negatively influence the environment. Therefore, a more promising alternative recycling process is needed to convert this waste into oil by cracking, and the process is possibly assisted by adding empty palm oil bunches. This study examines how modifications in the ratio of oil palm empty bunches to Polypropylene (PP) plastic waste influence the percent liquid produced by cracking and the heating value during the process. It is a completely randomized design (CRD) with variations in the ratio of plastic raw materials: oil palm empty fruit bunches 1:0, 1:1, 1:2, and 1:3 at a temperature of 450°C and 40 minutes duration. This resulted in liquid conversion from cracking of 80% at 1:1 of PP: TTKS 1:1. However, the addition of oil palm empty fruit bunches to polypropylene polymers does not affect the increase in the percent conversion outcomes. The results of the heat test analysis show the value of 6.681 MJ/kg and 1.512 MJ/kg. Keywords: Cracking, catalytic cracking, polypropylene plastic, biomass, alternative energy

Abstract

Cassava starch has been widely explored as film forming material, however its hydrophilicity restricts its application. Hydrophobic material such as modified starch can be used in the film elaboration to improve its quality. This study aims to examine the effect of modified cassava starch concentration on the physical, barrier, and mechanical properties of edible films. A completely randomized design was used with 5 concentrations of modified starch at 0%, 5%, 10%, 15%, and 20% and 4 repetitions to obtain a total of 20 experimental combinations. The ANOVA showed that the modified starch concentration affected the compressive strength, thickness, transparency, and solubility of the edible film, but has no effect on its water vapor transmission rate (WVTR). Usage of 20% modified starch gave the product with the best characteristics at 0.22 mm thickness, 89.45 N/m2 strength, 6.484%/mm transparency, 52.19% solubility, and 21.00 g/m2.hour WVTR.

Abstract

Purple yam tuber is known to contain a lot of bioactive components useful for human health. This study was conducted to utilize the tuber in form of purple yam flour for crackers processing and to understand the effect of purple yam flour concentration on the characteristics of crackers.  A completely randomized design was applied using several concentrations of purple yam flour (0, 10%, 20%, 30%, 40%, and 50%) and 3 replications. The concentration of purple yam flour affects volume expansion, color values (L*, a*, and b*) and anthocyanin content of the crackers, but did not affect its water content and texture. The higher concentration of purple yam flour decreased volume expansion, L*, b*, and overall acceptance of the crackers, but increased the anthocyanin content and a* values.  This research proposes that 30% purple yam flour shall be applied to partly substitute wheat flour in crackers processing.  At this concentration, crackers were accepted by the panelist (like it slightly) and has hardness value 287.2 gF, L* 70.35, a* 11.12, b* 20.18, 2.5% water, and anthocyanin content 179.6 mg cyanidin3-glucoside equivalent/g.

Abstract

This study aimed to determine the effect of yam starch and chitosan based-bioplastics packaging on the microbiological and sensory qualities of pempek during storage. This research was carried out by packing pempek using 2 different packaging: bioplastics and polyethylene plastic. Pempek in each group was stored for 0, 8, 16, 24, 48 hours at room temperature. The total of Staphylococcus aureus bacterial was determined using colony forming unit. Sensory quality was obtained by determination of color, texture and aroma of pempek using 5 skilled panelists. The result showed that the use of bioplastics packaging from yam starch and chitosan decreased the growth of Staphylococcus aureus bacteria in pempek compared to the use of polyethylene plastic packaging. The decrease in pH was in line with the growth of S.aureus that is higher in pempek packaged with polyethylene plastics. The use of bioplastics also maintained sensory qualities of pempek during storage better than polyethylene plastics

Abstract

Adsorben penelitian ini adalah zeolit, manganese green dan karbon aktif. Zeolit sebagai adsorben kesadahan air, penukar kation, dan penetralan pH dalam air. Untuk menyaring kekeruhan Manganese green berperan dalam hal tersebut. Karbon aktif menyerap ion logam berat Pb2+ serta menghilangkan bau, rasa dan warna. Karbonisasi sabut pinang efektif untuk penurunan konsentrasi TSS, bau, warna, pH, Fe, Pb serta mikroba. Sabut buah pinang mengandung flavanoid, alkaloid, hemiselulosa (32.98%), seluloasa (63.20%), lignin (7.20%), lemak (0.64%) dan pektin. Senyawa tersebut menjadi bahan dasar pembuatan karbon aktif.  Pengujian pH sebelum filtrasi 6.67 dan sesudah filtrasi 6.38. Pengujian parameter Total Suspennded Solid mimiliki hasil uji sebelum filtrasi 56 mg/L dan sesudah filtrasi 8 mg/L. Pengujian kadar konsentrasi Fe sebelum filtrasi adalah 2.6667 ppm dan sesudah filtrasi 2.4630 ppm. Pengujian kadar Mn sebelum filtrasi 1.7881 ppm dan sesudah filtrasi 1.3475 ppm. Hasil analisis mengalami penurunan kadar konsentrasi Fe dengan tingkat efektifitas sebesar 7.638 % dan Mn 24.640 %. Luas permukaan adsorben akan semakin besar dikarenakan kecilnya ukuran adsorben. Semakin besarnya luas permukaan adsorben maka semakin banyak pori yang terbentuk per satuan partikel adsorben. Bahan penyerap, ukuran butir, derajat keasaman, waktu serap, dan konsentrasi merupakan proses dalam penyerapan adsorpsi.
