Abstract

Rural agroindustry can absorb a relatively high labor rate, but the added value of the products is very low, resulting in low labor productivity. This research aims at describing the process of sugarcane into brown sugar and analyzing the added value of brown sugar agroindustry as well as its distribution in Bukik Batabuah Village, Canduang Agam Sub-district. The data were collected from six brown sugar processing home industries. This research found that there were three kinds of brown sugar namely saka kariang, saka gatah kuniang and saka gatah merah, which were only different in the time of cooking, storage process of tengguli, and heating of tengguli on saka gatah processing. These made the three types of brown sugar have different texture, taste, color and price. From their added value, saka kariang and saka gatah kuniang were classified as medium products, while saka gatah merah was classified as a low product. In addition, this research reveals that the smallest added value distribution was received by paid labors. Based on the findings, the following suggestions are recommended: (1) the brown sugar business should focus on developing a business of saka kariang processing; and (2) the added value of brown sugar could be enhanced by the use of effective and efficient production machinery, so that the added value distributed to the brown sugar agroindustry could be improved

Abstract

Using fruit branch for pepper shrub propagation is one of alternatives for an efficient pepper multiplication which usually uses underlayer cuttings. This research is aimed at finding the growth response of two pepper (Piper nigrum L.) cuttings to the administration of IBA (Indole Butyric Acid) and NAA (Naphthalene Acetic Acid). This research was conducted at the greenhouse of the Faculty of Agriculture, University of Sumatera Utara, Medan (± 32 m above sea level), from April to August 2017 using a factorial randomized block design with 2 factors, pepper branch cuttings (primary branch cuttings and secondary branch cuttings) and the administration of IBA and NAA (0+0 ppm, 2500+0 ppm, 0+2500 ppm, 1500+1000 ppm, and 1000+1500 ppm). The results show that the emerging shoot rate in the secondary branch cuttings was significantly faster than in the primary branch cuttings, but the volume of root in the primary branch cuttings is significantly larger than in the secondary branch cuttings. There was no significant difference in the administration of IBA and NAA on all observed variables. The highest interaction of shoot length was found in the primary branch cuttings with the administration of IBA 1500 ppm + NAA 1000 ppm and the highest percentage of root and root volume was found in the primary branch cuttings with the administration of IBA 2500 ppm + NAA 0 ppm.

Abstract

Red betel leaf (Piper crocatum) is a plant growing in tropical areas and previously known as an ornamental plant, but then later used as medicinal plant. Previous researches found that red betel leaves contain bioactive compounds such as alkaloids, flavonoids, tannins, and many more that have potential to be used as antioxidant. The extractions were carried out using variations of solvent types (ethanol, water, and ethyl acetate) and feed to solvent (F:S) ratios in g/ml (F:S=1:20, F:S=1:25, F:S=1:30). The best conditions from this research were the usage of ethanol as the solvent. In addition to its ability to extract the compounds potential as antioxidant and F:S ratio of 1:30, it could give highest yield of extract. Variation of solvent type and variation of F:S have significant effect on the value of antioxidant activity (IC50) of the red betel leaf sample.

Abstract

Ginger and turmeric can be used as feed additive in the quail’s rations. An active substance in this Zingiberaceae family has good benefits for animals, especially quails. A research on the Quail Performance at the Starter-Grower Period fed commercial feed with the addition of ginger and turmeric had been conducted over the past five weeks. The purpose of this research was to know the effect of feed additive (ginger and turmeric flour) on the quail’s performance since the starter period up to the grower period. The data were 240 two day old quails. The experimental design used was a Complete Random Design (CRD) with 4 treatments and 4 replications, i.e. P0: feed controls without any addition, P1: addition of 1% ginger flour; P2: the addition of 1% turmeric flour; P3: the addition of 0.5% ginger flour plus 0.5% turmeric flour. The observed variables were the consumption of rations, body weights, FCR, mortality and depletion. The results showed that each of the treatment was not significantly different or had no effect on the performance of quails at the starter-grower period. It is necessary to do similar research by increasing the percentages administered to each of the treatments, so that the effect of administering the feed additive; i.e. ginger flour and turmeric flour can be obtained.

Abstract

A strategic alternative step for the development of cultivation of feed crops is to optimize the use of dry land that has the potential for agricultural and livestock business. One of the forage plants that has good adaptation to less good soil condition and is a pioneer plant, Pueraria javanica legume, so it can be considered as a potential alternative forage as animal feed. The research aims at determining the effect of various levels of drought stress treatment on the plant hight, fresh matter production, dry matter production and root biomass of Pueraria javanica legume. The experiment was conducted in the Greenhouse of the Agriculture Faculty of Universitas Sumatera Utara. The experiment was carried out using a completely randomized design (CRD) with 3 treatments and 4 replications. The treatments were A1 (25% field capacity (FC)=144 ml/polybag, A2 (50% FC)=288 ml/polybag and A3 (100% FC)=576 ml/polybag. The results show that Pueraria javanica legume can survive and grow up to severe drought stress (25% FC) but the crop production does not increase when compared to the field capacity condition; besides, the legume cannot survive longer in drought condition. The volume of water supplied corresponding to the field capacity makes the plant growth better.

Abstract

Climate change is one of serious threats to the agricultural sector. In North Sumatra Province, climate change is characterized by shorter rainy season with higher rainfall. To overcome such climate change, it is necessary to provide irrigation that can accommodate excessive rain water and distribute it in times of shortage. Therefore, changes in rainfall will not be too influential on productivity. This is especially important for plants that need a lot of water like rice. To analyze the influence of irrigation in North Sumatra Province, the data were collected from 27 regencies/cities in 2011 – 2015 and were analyzed using a Simple Linear Regression analysis model. The estimation results show that irrigation can push the productivity variances. The irrigation regression coefficient of -0.133432 shows that each increase of irrigation area by 1% will decrease the productivity variation by 0.13 tons/ha

Abstract

The torch ginger (Etlingera elatior) is a herbaceous plant the flower of which is commonly used in feed to improve the quality of meat. This study was aimed at assessing the effects of giving commercial feed non-carcass portions of local ducks. The study was conducted at the Poultry Farm of Department of Animal Husbandry Djuanda University, Bogor, from June to August 2016. Twenty four 2-week-old male local ducks were used. Completely randomized design with 4 treatments and 3 replicates was used. The treatments consisted of 100% of commercial ration (R0), commercial ration + 2.5% of TGE solution (R1), commercial ration + 5% of TGE solution (R2), and commercial ration + 7.5% of TGE solution (R3). The feeding trial lasted 6 weeks after which the ducks were slaughtered and carcass weight, dressing percentages and carcass parts were measured. The percentage of non-carcass parts including head, neck, shank, liver, heart, gizzard, feathers, blood and intestines were also measured. No significant effect of treatments (P > 0.05) on all parameters measured were found. It was concluded that the inclusion of TGE solution in commercial ration up to 7.5% did not significantly affect the live weight, weight and percentages of non-carcass parts including blood, feathers, head, neck, shank, liver, gizzard, heart, and intestines.
