Abstract

Earthworm (Lumbricus rubellus) is known to contain proteins making it suitable for alternative high-protein resources for  feed or animal food. Exctraction of proteins from earthworms is not an easy task and it requires multiple steps for purifying the protein extract. Furthermore, the extraction of earthworm protein is considered as uneconomical due to high operational cost. Therefore, altering the process is necesarry to enhance the extraction. The objective of this research is to optimize the solubility of protein from earthworm juice. The design used in this research is a completely randomized design consisting of two factors which are A (earthworm concentration) and B (extraction time). The results show that solubility of protein was 28.12% and the soluble solid was 67.63%. The optimum process includes earthworm concentration of 15% and extraction time of 90 minutes.

Abstract

Abstrak Penelitian ini bertujuan untuk mengetahui pengaruh waktu dan gaya tekan terhadap kekerasan dan waktu larut tablet effervescent dari serbuk wortel. Penelitian dilakukan menggunakan rancangan acak kelompok yang disusun faktorial dengan dua faktor, yaitu gaya tekan (F) dan waktu (T). Parameter yang diuji adalah kekerasan, waktu larut dan total karoten tablet effervescent. Hasil analisis kekerasan didapatkan rerata 0,98 kg/cm2 sampai dengan 1,11 kg/cm2 . Hasil analisis waktu larut didapatkan rerata 55,12 detik sampai dengan 63,61 detik. Analisis ragam kekerasan dan waktu larut menunjukkan ada pengaruh nyata dari waktu (T) dan gaya tekan (F), namun tidak ada interaksi. Hasil analisis total karoten didapatkan rerata 13,37 μg/g sampai dengan 14,01 μg/g. Analisis ragam total karoten menunjukkan tidak adanya pengaruh antar faktor, yang menunjukkan bahwa waktu dan gaya tekan tidak mempengaruhi nilai total karoten tablet effervescent dari serbuk wortel. Pemilihan perlakuan terbaik didapatkan dari perlakuan F1T3, yaitu dengan proses pengepresan pada total tekanan sebesar 1250 kg/cm2 dan waktu 15 detik. Dari perlakuan tersebut didapatkan nilai kekerasan sebesar 1,06 kg/cm2 , waktu larut 56,93 detik dan total karoten sebesar 14,10 μg/g.Kata Kunci : Effervescent, Kekerasan, Total Karoten, Waktu Larut, dan WortelAbstract This research was purposed to find the effect of time and compression force on hardness and soluble time of effervescent tablet from carrot’s powder. This research used grop random design that was arranged factorial by two factors, that are compression force (F) and pressing time (T). Parameters tested are hardness, soluble time dan total carotene. The result of hardness tablet analysis was reached average value 0.98 kg/cm2 until 1.11 kg/cm2 . The result of soluble time tablet analysis was reached average value 55.12 second until 63.61 second. The hardness and Soluble time of analysis variant tablet showed that founded a real different from pressing time (T) and compression force (F), but there is no interaction. The result of total carotene analysis was reached average value 13.37 μg/g until 14.01 μg/g. The total carotene of analysis variant tablet showed that there was no real different from pressing time (T) and compression force (F), that mean those factors didn’t influince value of total carotene effervescent tablet from carrot’s powder. Best treatment was reached from F1T3, that used 1,250 kg/cm2 compression force on 15 second. That treatment has 1.06kg/cm2 hardness value, soluble time 56.93 second and value of total carotene is 14.10 μg/g.Keywords : Carrot, Effervescent, Hardness, Total carotene and Soluble Time

Abstract

Macroalgae as the marine renewable biomass has great potential for production of bioenergy and bioproduct with integrated biorefinery concept. However, high lignin content may hinder the valorization. Same conditions applied for the macroalgae in Indonesia which has the great opportunity to explore more in the bioenergy field. This study aimed to investigate potential application of macroalgae as substrates for bioenergy production, specifically with anaerobic digestion (AD) technology. Anaerobic digestion as the one of the ways to transform macroalgae into biogas. This review analyses the latest study’s results from the view of composition, degradation, and the biorefining pathways. The biomass is constructed from lignocellulose compounds and have thick cell wall that be the main drawbacks for the biochemical conversion technology. Various enhancement pathways have been studied i.e., pretreatment methods to enhance the accessibility for microorganisms, reduce the outer cell wall thickness, and co-digestion with addition of other substrates to balancing the nutrition and providing the stable condition for AD system. In term to have more feasibility from economic view, the strategy is put in the biorefinery concept to have more valuable-added products. The decrement of energy input, higher of energy output and yield of outcome along with some products being produced are expected to gain from the proposed ways. Those information will provide new research directions and solutions for converting Indonesia marine macroalgae using AD technology.

Abstract

In this study, bioethanol production was carried out at a high temperature (40 0C) using Kluyveromyces marxianus in sugar cane molasses media with a study of combinations in fermentation conditions in the form of inoculum concentration and agitation speed. This study investigated the effect of inoculum concentration and agitation speed on bioethanol production. This study used a factorial randomized block design with two factors: inoculum concentration (with levels of 5%, 10%, and 15% (v/v)) and agitation speed (with levels of 100, 150, and 200 rpm). The results showed that the interaction of inoculum concentration and agitation speed significantly decreased pH, total sugar consumption, total reducing sugar  (TRS) consumption, and total dissolved solids (TDS). However, an increase in cell optical density (OD), ethanol concentration, and ethanol yields was evident from all treatments. The best treatment was from a combination of 10% inoculum with an agitation speed of 150 rpm, giving the highest ethanol concentration of 3.44% and ethanol yields of 89.91%.

Abstract

A field experiment to examine the effect of weeding and reducing the number of branches on tomato plants (Lycopersicon esculentum Mill.) on weed diversity and density was carried out in the Griya Santa research area, Lowokwaru District, Malang City with andosol soil type. This experiment was designed in a factorial randomized block design (RBD) with 2 factors and 3 replications. The first factor is: the weeding period (P) which consists of 3 weeding periods, i.e. without weeding (P0), 2 times weeding at 30 and 58 days after planting (P1) and 3 times weeding at 30, 44 and 58 days after planting (P2). The second factor was: pruning the number of tomato plant branches (W) which consisted of 3 levels, namely: Without pruning branches (W0), Pruning branches leaving 2 branches (W1) and Pruning branches leaving 4 branches (W2). All treatment plots were repeated 3 times. The experimental results showed that at 30 DAP (P0W0) there were 2 dominant weeds namely Portulaca oleraceae and Cyperus rotundus. At 44 DAP it showed that there were also 2 dominant weeds namely: Ricinus communis and Cyperus rotundus. The most dominant P2W0 weed treatments were Ricinus communis and Ageratum conyzoides. The P0W1, P1W1, P0W2, and P1W2 treatments had weed species: Ricinus communis and Cyperus rotundus. The dominant weeds found in the P2W1 and P2W2 treatments were Ricinus communis and Portulaca oleraceae.
