Lontar palm (Borassus flabeliffer L.) fruit is one of the specific tropical fruits from East Nusa Tenggara province (NTT)-Indonesia that is rich in functional compounds such as beta-carotene as an antioxidant and food fiber. However, the utilization of these fruits is still limited due to the streroidal saponins and pholifenol content that makes them taste bitter and less favored by consumers. Therefore, one alternative that can be done is by enriching them into ice cream products. The production of Ice cream cannot go through with high heating processing so that the antioxidants extracted from lontar palm mesocarp can be in a stable condition. The aim of this study is to investigate the effect of ice cream on the acceptability values of the hedonic test, determining of fiber and beta-carotene content and evaluating antioxidant activities fortification from the lontar's mesocarp. The amount of lontar mesocarp for fortification (F) were 30%, 40% and 50% of the wet weight with the combination of some variation of milk treatment such as full cream milk, sweetened condensed milk, and liquid soy milk. The acceptability of the product was tested using hedonic test against color, aroma, texture, and flavor parameter. Antioxidant activity was performed by determination of the DPPH value (1.1-diphenyl-2picryhydrazil radical-scavenging), dietary fiber using enzymatic-gravimetric methods and UV-Vis spectrophotometers to analyze the content of beta-carotene. The results showed that on the acceptability test, the most preferred samples valued by panelists were the fortification, F1 treatment (30%) with the content of β-carotene of full cream milk was 2212.44 ± 11.82 μg /100 mg, dietary fiber was 8.95 ± 0.05%, and antioxidant activity was 45.54 ± 0.36%.

Angkak, commonly used for food colorant and flavor enhancers in oriental cuisine, is the result of fermentation by Monascus purpureus on steamed rice. In addition to producing pigments Monascus purpureus, Angkak also produces mycotoxins, citrinin, which is hepato-nephrotoxic. Biosynthesis of pigment and citrinin is following a polyketide synthase pathway and then subdivides to form pigment or citrinin. Fatty acids and amino acids are known to be the precursors of red pigment formers in their biosynthetic pathways. The purpose of this research was to know the effect of addition of lauric fatty acid and amino acid glycine on steamed rice substrate to the color characteristic and citrinin level by M. purpureus JK9A. The amount of fatty acid and glycine was respectively 0.5% and 1% (w/w). Fermentation was carried out for 14 days and every two days the solids content of fermented products, pH, number of cells, colors, pigments dissolved in water were measured. The level of citrinin was tested at the end of the fermentation period (14th day). There was no significant difference between treatments for the solids content of about 23 ̶ 29% and the number of cells 6.32 ̶ 6.56 logCFU/g. While the pH value, color and water-soluble pigments were significantly different between treatment and control. The ˚hue values of glycine and combination of lauric-glycine were 16.11 and 15.33, respectively, lower than controls (22.76). The highest A500nm/A400nm ratio was in the combination treatment of lauric-glycine and the lowest levels of citrinin also in the treatment of lauric-glycine combination. This study noticed that the addition of lauric or glycine and its combination in rice media for Monascus purpureus JK9A fermentation proved to increase the biosynthesis of red pigment (46.34%) and decrease citrinin level up to 49.97%.

Java contributes 63.7% of national sugar production, in which 55.6% is produced by the farmer from 312,973 ha of sugarcane area (65.6% of Indonesia’s cane crop area). Farm labor in Java was very limited in the past two decades, so was needed mechanization. Howeveer, the size of agricultural machines were not accordance with the size of land, the limited of spares, and was not optimally managed. This research aimed to calculate operational cost of farm machinery (hand tractor) on the cane cultivation activities up to 6-month cane growth period. This study was carried out at Comal, Center of Java at alluvial land 8 mdpl and at Pasuruan, East Java at alluvial 10 mdpl. From each location, 2 plots of 0.1 ha were observed. The treatments were manual and machine cultivation with 3 replications. The observed agrotechnical parameters were the bud emergence, number of stalk, clump, stalk height and diameter, and operational cost of using machinery. The agrotechnical result using t-test (95% confidence rate) showed no significance among treatments. Other results revealed that using machinery for fertilizing, soil heaping up, and soil moving (gulud) in Pasuruan can substitute manual daily worker (HOK) for 6 HOK, 12 HOK and 20 HOK, respectively, using tractor by 7 hours/day. Meanwhile in Comal, using machinery for fertilizing, soil heaping up, and soil hilling up (gulud) can substitute manual daily worker (HOK) for 9 HOK, 16 HOK, and 20 HOK, respectively. The cost analysis indicated the 35.54% reduction of using machinery compared to the manual expense. This study revealed that the machinery could substitute the manual worker for cane cultivation.

In order to determine soil characteristics and above-ground and below-ground carbon sequestration potential of wheat, a systematic random sampling method was employed to select 5 samples from 50 fields situated in Khorasan-Razavi Province, Iran during 2015. The experimental design was a completely randomized design with three replications. The ash method was used to determine the carbon sequestration conversion coefficients in spikes, stems, leaves and roots. Then, greenhouse gases (such as CO2, N2O and CH4) emission were calculated using emission coefficients. The average organic carbon, total nitrogen, available phosphorus, available potassium, soil bulk density, pH and electrical conductivity were found to be 0.98%, 0.02%, 27.07 ppm, 341.32 ppm, 1.37 g.cm-3, 7.81 and 1.42 dS.m-1, respectively. The maximum (52.0%) and minimum (31.99%) conversion coefficients were related to spikes (seeds included) and roots, respectively. In addition, the total carbon sequestration was 8.25 t.ha-1 so that the maximum (4.28 t.ha-1) and minimum (0.35 t.ha-1) values were found in stems and roots, respectively. The total global warming potential (GWP) of wheat was recorded as 2377.86 kg CO2 –equiv. per ton of seed. The first contributing factor was nitrogen fertilizers, accounting for 1331.30 kg CO2 –equiv. per ton of seed.

Tamarillo is an underutilized fruit in Indonesia, despite the fact that it contains two pigments (anthocyanin and carotenoid) with different properties (polar and non polar). Besides, there is a scarce information about extraction of anthocyanin and carotenoid of Tamarillo using sonication extraction. This study was aimed to investigate the comparison of extraction methods of sonication with maceration on antioxidant potency of anthocyanin and carotenoid of Tamarillo. Two pigmen types (anthocyanin and carotenoid) were extracted using two different methods (sonication and maceration). The parameters of analysis were yield, antioxidant activity (DPPH) with IC50, Ferric Reducing Antioxidant Power (FRAP), anthocyanin total, carotenoid total, phenolic total and scanning electron microscope of cover cell of material. The antioxidant potencies for both anthocyanin and carotenoid by sonication method were higher than those of obtained by maceration method. The results showed that both sonication and maceration were suitable for extraction of anthocyanin and carotenoid from Tamarillo.

This study was aimed to examine effect of inoculation with Arbuscular Mycorrhizal Fungi (AMF) and intercropping with several mungbean varieties on yield components of red rice grown under aerobic irrigation technique. The experiment was carried out in a pot in the plastic house from June to September 2017. The experiment was designed using Completely Randomized Design with two treatment factors arranged factorially, i.e. AMF inoculation (M0= without, or M1= with AMF inoculation) and mungbean varieties (V) grown together with red rice plant (V1= Kenari, V2= Vima-1, V3= Vima-3, V4= Merak, and V5= No. 129 ). Each treatment combination was made in triplicate. The results indicated that inoculation had a significant effect in increasing filled panicle number, number of filled grains, and dry grain yield per pot, while decreasing percentage number of unfilled grains. For the rice plants incoluated with AMF, intercropping with mungbean of Kenari and Merak varieties produced similar or higher number of filled panicles compared to those without intercropping. In contrast, for the rice plant without inoculation with AMF, intercropping resulted in lower amount of filled panicles than those without intercropping.

Industrial wastewater treatment using Sequencing Batch Reactor (SBR) can improve effluent quality at lower cost than that obtained by other biological treatment methods. Further optimization is still required to enhance effluent quality until it meets standard quality and to reduce the operating cost of treatment of high strength organic wastewater. The purpose of this research was to determine the effect of pretreatment (pH adjustment and prechlorination) and aeration time on effluent quality and COD removal rate in tapioca wastewater treatment using SBR. Pretreatment was done by (1) adjustment of tapioca wastewater pH to control (4.92), 7, and 8, and (2) tapioca wastewater prechlorination at pH 8 during hour using calcium hypochlorite in variation dosages 0, 2, 4, 6 mg/L Cl2, SBR operation was conducted according to following steps: (1) Filling of pre-treated wastewater into a bioreactor during 1 hour, and (2) aeration of the mixture of tapioca wastewater and activated sludge during 8 hours. Effluent sample was collected at every 2-hours aeration for COD analysis. COD removal rate mathematical formula was got by first deriving the best fit function between aeration time and COD. Optimum aeration time resulting in no COD removal rate. The value of COD effluent and its removal rate in optimum aeration time was used to determine the recommended of operation condition of pretreatment. Research result shows that chosen pH operation condition is pH 8. Prechorination can make effluent quality which meets standard quality and highest COD removal rate. The chosen Cl2 dosage is 6 mg/L.
