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.

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.

AbstractPlants perceive and respond to volatile signals in their environment. Herbivore-infested plants release volatile organic compounds (VOCs) which can initiate systemic defense reactions within the plant and contribute to plant-plant communication. Here, for Ipomoea batatas (sweet potato) leaves we show that among various herbivory-induced plant volatiles, (E)-4,8–dimethyl–1,3,7-nonatriene (DMNT) had the highest abundance of all emitted compounds. This homoterpene was found being sufficient for a volatile-mediated systemic induction of defensive Sporamin protease inhibitor activity in neighboring sweet potato plants. The systemic induction is jasmonate independent and does not need any priming-related challenge. Induced emission and responsiveness to DMNT is restricted to a herbivory-resistant cultivar (Tainong 57), while a susceptible cultivar, Tainong 66, neither emitted amounts comparable to Tainong 57, nor showed reaction to DMNT. This is consistent with the finding that Spodoptera larvae feeding on DMNT-exposed cultivars gain significantly less weight on Tainong 57 compared to Tainong 66. Our results indicate a highly specific, single volatile-mediated plant-plant communication in sweet potato.

Sweet potato (Ipomoea batatas L.) is one of alternative food sources beside than rice. Sweet potatoes are contains minerals, nutrients, sources of energy, protein, vitamins A and C. Sweet potatoes have lower productivity than rice and cassava. The low productivity of sweet potatoes due to several factors, which one of them is a leaf scab disease caused by pathogens Sphaceloma batatas Saw. The purpose of this study is to determine the character of the anatomy of sweet potato leaf cultivars that resistant and unresistant to the intensity of leaf scab disease, as well as the correlations between the anatomy character of sweet potato leaves with leaf scab disease intensity. The method used in this study is an experimental method with factorial completely randomized design. The first factor is the character of the anatomy of four cultivars sweet potato leaves, Cangkuang and Sukuh cultivars (cultivars resistant), cultivars Cilembu and Beta (unresistant cultivars). The second factor is the inoculation treatment S. batatas Saw. The parameters were observed thickness of cuticle, epidermis, mesophyll, the size (length and width) stomata, density of stomata and trikomata as well as the intensity of the disease were analyzed using analysis of variance (ANOVA). To determine the correlation between the anatomy character leaves with disease intensity using regression correlation analysis. The results showed that Cangkuang cultivar has cuticle, epidermis and mesophyll thickest. Beta cultivars have stomata size of the longest and widest. Cilembu cultivar has the highest density of stomata. Sukuh cultivars has the highest density. The anatomy characters include of a thick cuticle, epidermis, stomata size (length and width), as well as the density of stomata and trikomata correlated with intensity of leaf scab disease.

Papaya (Carica papaya L.) and purple sweet potato (Ipomoea batatas L. Lam) are commonly used empirically as traditional medicines, including for malaria, malnutrition, fever and hemorrhagic fever. The purpose of this study was to determine the effect of differences in the concentration of ethanol solvents on the chromatogram profile and compound content. The research method began with maceration using 50%, 70%, and 96% ethanol, then thin layer chromatography test, and determination of total phenol and flavonoid levels with Elisa at λ of 750 nm and 415 nm, where the comparator used were gallic acid and quercetin . The results of total phenol levels obtained in papaya leaf extract were 3,493 mg GAE/gram and in sweet potato leaves the results were 4,786 mgGAE/mg. While the total flavonoid yield obtained from papaya leaf extract was obtained as much as 4,630 mg QE/gram and on sweetpotato which was 4,269 mgQE/mg. Characterisation of extract compound content was carried ouy by using Gas Chromatography- Mass Spectroscopy (GC-MS), where comparison of extracts used in extract combination samples are 50:50, 75:25, and 25:75. The results showed that ethanol extract contained alkaloids, flavonoids, saponins, tannins, and triterpenoids. Characterization by using GC-MS for single extract and combination extract of papaya leaves and purple sweet potato leaves obtained the main active compounds are Phytol, Neoheptadine, and n-Hexadecanoic acid.
