Abstract This study aims to evaluate the milk lactose, specific gravity, and mineral of Etawa Crossbreed Dairy Goat (ECDG) fed with palm kernel cake-based concentrate (PKCC), tithonia (Tithonia diversifolia), sweet potato leaves, (Ipomoea batatas L.), and Gamal (Gliricidia sepium) as a source of roughage. The design of the experiment used was a completely randomized design (CRD) with four treatment rations and four replications. Treatment formulations are as follow A). 100% basal ration (BR); B). 50% BR + 50% Concentrate Based Palm Kernel Cake (CPKC) + tithonia; C). 50% BR+ % CPKCC + sweet potato leaves; D).50% BR + 50% CPKC + Gamal (Gliricidia sepium). The ratio of concentrate and roughage is 50:50. The concentrate ratio consists of 30% palm kernel cake, 40% tofu waste, 20% rice bran, 9 % corn, and 1% mineral. The parameters were milk lactose, specific gravity, and mineral of milk. Data were analysed by Analysis of Varian (ANOVA) and DMRT (Duncans Multiple Range Test) according to Steel and Torrie (2002). The results showed that the treatment had no significant effect (P> 0.05) on lactose, specific gravity, and mineral of milk. From this study, it can be concluded that the use of PKC, titonia, sweet potato, and gamal can replace basal ration without affecting the quality of milk (lactose, specific grafity and mineral)

Abstract. Arief, Rudimansyah, Sowmen S, Rizqan RP. 2020. Milk production and quality of Etawa crossbreed dairy goat that given Tithonia diversifolia, corn waste and concentrate based palm kernel cake. Biodiversitas 21: 4004-4009. The research aims to evaluate the production and quality of goat milk of Etawa crossbreed dairy goat (ECDG) which is fed by Tithonia diversifolia (T), corn waste (CW), and concentrate-based palm kernel cake (CBP),. The experimental design used in this study was a completely random design (CRD) with four times treatment rations and five times replications. There are five treatments used in this research which are; treatment A used 60 % T + 40 % tofu-dregs; B used 60 % T + 20% tofu-dregs + 20% CBP; C used 45 % T + 15% CW + 20% tofu-dregs + 20% CBP; D used 30 % T + 30% CW + 20% tofu-dregs + 20% CBP. The data were analyzed by Analysis of Varian (ANOVA) and Duncan's Multiple Range Test (DMRT) for further tests. The parameters measured were milk production and milk quality, which covers dry matter, water content, protein, fat, solid non-fat, and lactose. The result showed that the treatment gave no significant effect (P> 0.05) of milk production, dry matter, protein, fat, solid non-fat, and lactose. The study concluded that the use of T. diversifolia, corn-waste, and CBP could maintain milk production quality.

The Impact

The study aimed to evaluate the effects of process parameters (time and raw material weight (RMW)) of conventional (boiling for 10–45 min) and microwave-assisted (2–8 min) aqueous extraction on the color quality (i.e., lightness (L*), chroma (C*), and hue (H°) of anthocyanin –based colorants of red and Inubi sweet potato (Ipomoea batatas L.) leaves. Using response surface methodology, it was found that RMW and boiling time (BT) and microwave time (MT) generally had a significant (p < 0.05) effect on the color quality of the extract from both extraction methods. The effects were found to vary depending on the extraction method and variety of the leaves used. Both extraction methods produced a brown to brick-red extract from the Inubi variety that turned red-violet to pink when acidified. The red sweet potato leaves produced a deep violet colored extract that also turned red-violet when acidified. It is recommended that the anthocyanin content of the extracts be measured to validate the impact of the methods on the active agent. Nevertheless, the outcomes in this study may serve as baseline data for further studies on the potential of sweet potato leaf colorants (SPLC) as a colorant with functional properties.

Sweet Potato Leaves

Phytochemical-enriched edible greens, sweet potato leaves (Ipomoea batatas L.), have become popular due to potential health benefits. However, the phytochemical contents in sweet potato leaves and their subsequent change over harvest stages and growth condition are mostly unknown. In this study, the anthocyanin profile and content in leaves of four sweet potato cultivars, i.e., white-skinned and white-fleshed Bonita, red-skinned and orange-fleshed Beauregard, red-skinned and white-fleshed Murasaki and purple-skinned and purple-fleshed P40, were evaluated. Fourteen anthocyanins were isolated and identified by HPLC-MSI/MS. The most abundant was cyanidin 3-caffeoyl-p-hydroxybenzoyl sophoroside-5-glucoside, which comprised up to 20% of the total anthocyanins. Of the young leaves (1st and 2nd slip cuttings), Bonita contained the highest anthocyanin content followed by P40. Of the mature leaves (vine stage), Beauregard had the greatest anthocyanin (592.5 ± 86.4 mg/kg DW) and total phenolic (52.2 ± 3 mg GAE/g DW). It should be noted that the lowest anthocyanin and total phenolic content of shoots were found in P40, while tubers of P40 contain the highest content of each. Furthermore, the increase in leaf anthocyanin content over the growth stages that was observed in three of the cultivars but not in P40. No significant difference of anthocyanin content was found in Beauregard leaves grown in the high tunnels when compared with that in the open field. This study demonstrated for the first time that anthocyanin levels were significantly changed in response to various growth stages but not high tunnel condition, indicating that the effect of anthocyanin biosynthesis in sweet potato leaves is highly variable and genotype specific.

Fast Prediction

Taro (Colocasia esculenta (L.) Schott) and sweet potato (Ipomoea batatas (L.) Lam.) are important food crops worldwide, whose productivity is threatened by climatic constraints, namely drought. Data calibration, validation, and model development of high-precision near-infrared spectroscopy (NIRS) involving multivariate analyses are needed for the fast prediction of the quality of tubers and shoots impacted by drought stress. The main objective of this study was to generate accurate NIRS models for quality assessment of taro and sweet potato accessions (acc.) subjected to water scarcity conditions. Seven taro and eight sweet potato acc. from diverse geographical origins were evaluated for nitrogen (N), protein (Pt), starch (St), total mineral (M), calcium oxalate (CaOx), carbon isotope discrimination (Δ13C), and nitrogen isotopic composition (δ15N). Models were developed separately for both crops underground and aboveground organs. N, Pt, St, and M models could be used as quality control constituents, with a determination coefficient of prediction (r2pred) between 0.856 and 0.995. δ13C, δ15N, and CaOx, with r2pred between 0.178 and 0.788, could be used as an informative germplasm screening tool. The approach used in the present study demonstrates NIRS’s potential for further research on crop quality under drought.
