Abstract

This research aimed to identify polymorphism of the GH gene in Sikumbang Jonti ducks using the PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism) method as a candidate for genetic marker selection. This research used 123 blood samples of male and female Sikumbang Jonti ducks. The ducks were eight weeks old and kept intensively at the UPT Fakultas Peternakan Universitas Andalas. Blood samples of Sikumbang Jonti ducks were taken through the brachial vein as much as ± 2 mL. The Genomic DNA Purification Kit (Promega) protocol isolated DNA from blood samples. A pair of primers F amplified the total DNA: 5'-GGA CAG CCT GAG GAA AGA GT-3 'and R: 5'-GTG GAA GGT GGG GAG ACT TC-3', which produced a fragment region of the GH gene exon 3 with a cut region of part intron two and part intron 3 with a primary length of 833 bp. The amplified product was restricted by the enzyme TasI which recognizes the cutting site (↓AATT). Based on the restriction results, two (2) genotypes were obtained, namely homozygous (-/-) as many as four (4) and homozygous (+/+) as many as 119. The analysis of restriction products included the allele frequency, namely the allele (+) of 0.98 and the allele (-) of 0.02, and genotypes frequency of homozygous (-/-) of 0.03 and homozygous genotypes (+/+) of 0.97. The diversity of the GH gene is in the Hardy-Weinberg equilibrium. Based on the research results, it can be concluded that there is diversity in the GH gene of the Sikumbang Jonti duck, and it is in the Hardy-Weinberg equilibrium, so it can be used as a candidate for the genetic marker of ducks.

Abstract

Melon is one of the horticultural commodities with relatively high economic value and is profitable to cultivate as a source of income for farmers. With the increasing demand for melons, melons are widely cultivated in Bengkulu. Pests and diseases are one of the most disturbing problems in melon cultivation. Plant parasitic nematodes are one of the pests of melon plants that are not paid enough attention to by farmers due to a lack of knowledge about nematodes. Losses caused by nematode attacks on melon plants resulted in decreased production. Information about the types of nematodes is crucial to design an effective control strategy. This study aims to identify the diversity and density of nematode populations on melon plants in the city of Bengkulu. Observation of nematode attacks was carried out directly by observing all parts of the melon plant, especially the roots, and identifying and counting nematode populations. Observation parameters included attack symptoms, types of nematodes, and nematode population densities. This research has been carried out with the results: Symptoms of attack on the ground: stunted plants, languishing, quickly wilted. The symptoms of attack in the soil: Root galls, root wounds, and root rot. There are four types of nematodes, namely Genus: Paratylenchus sp, Meloidogyne spp., Rotylenchulus sp., and Helicotylenchus sp., Paratylenchus sp. population density 131.6; Meloidogyne spp. 86.5 Rotylenchulus sp. 69.7 and Helicotylenchus sp. 47.8.

Abstract

Increased price volatility can increase investment risk and, at the same time, reduce investment. Food price volatility will have different effects on surplus and deficit households. Instead of investing, uncertainty in food prices can be a significant barrier for many deficit households to escape poverty. On the other hand, surplus households can save. Agricultural price shocks and volatility threaten the poorest people's access to food and economic welfare. The detrimental welfare impact on the consumers outweighs the gains to producers increasing the number of poor and in the depth of poverty. Decreased income in already low-income countries might result in malnutrition, death, and withdrawal of children from education. There is a substantial correlation between a country's food production index, poverty level, degree of urbanization and the risk that it will experience food riots, given the empirical evidence that shocks to agricultural prices can spark civil unrest and wars, as well as the devastating effects that civil wars and other forms of violence have on economic growth.

Abstract

National food security requires grain for food adequacy, which is then processed into rice as a cereal product, one of the most dominant food commodities for the majority of Indonesian people. The analysis of the ratio normative consumption per capita to cereal production shows that 39.66% of districts in Indonesia experience a deficit in food availability, partly due to population growth which an increase has not matched in cereal production. The purpose of this research is to perform forecasting on the amount of grain production as a reference in formulating a strategy for supplying grain to the population to fulfil the staple food consumption needs of the Indonesian population. This research method uses secondary data on grain production in Indonesia with a range of 2000-2021, and forecasting is carried out until 2024. The data source comes from the Central Statistics Agency (BPS), and data processing uses SPSS (Statistical Package for Social Science). Forecasting techniques use four methods: simple moving average, weight moving average, exponential smoothing and double exponential smoothing. Forecasting results for grain production in 2000-2024 were below actual production, and the peak of production increase occurred in 2017 and then decreased production until forecasting in 2024. The lowest values ​​for MAD, MSE and MAPE were for forecasting results using the WMA method.

Abstract

Favoured by Indonesian citizens, Cyprinus carpio production decreased over time due to diseases caused by Aeromonas hydrophila in the aquaculture process.  Antibiotics are often used to manage the disease on media, but they could cause resistance to the bacteria.  Herbs were used as the alternative for these antibiotics.  This experiment aimed to find the effect of Anredera cardifolia extract on the kidney histopathology of C. carpio infected by A. hydrophila.  The dosage used in this experiment was 200ppm, 400ppm, and 600ppm for each treatment with three repetitions.  There was also negative and positive control.  The bacteria density used for the positive control was 107 cells/ml.  After infection, kidney tissue was taken three days post-recovery.  Descriptive analysis was used to analyse the kidney histopathology, while to determine the level of the damage carried out by the bacteria, we used the scoring level.  This research showed that treating A. cordifolia affects the kidney histopathology of C. carpio infected by Aeromonas.  The damaged tissue found was necrosis, edema, and congestion.  The best dose used to improve the damaged kidney tissue on C. carpio was treatment B (400ppm), indicated by the scoring results for minor damage; the structure showed the tissue figure looked similar to the normal tissue.

Abstract

The main objective is to investigate the effect of DCfCaP-substitute concentrate on growth performance and feed efficiency in Thai native x Lowline Angus crossbred cattle. The average initial body weight (IBW) was assigned 97±18.5 kg and 1-year age, 12 females of  Thai native x Lowline Angus crossbred cattle. Dietary treatments were designed in a completely randomized design (CRD) to receive three feeding treatments, four replications per treatment with one cow per replicate. The feeding treatments were administered as follows: T1=100% concentrate + 0% DCfCaP (control), T2=67% concentrate + 33% DCfCaP, and T3= 33% concentrate + 67% DCfCaP on dry matter basis (DM). The results indeed showed that the initial body weight (IBW) and final body weight (FBW) were non-significantly different (P>0.05). The average daily gain (ADG) in T1 and T2 was 0.53 kg/day and 0.48 kg/day, and representative superscripts were in the same row, but there were differences in T3 was  0.05 kg/day (P<0.001). T1 used feed intake higher than T2 and T3 (P=0.003). So far, the feed conversion ratio (FCR) in groups T1 and T2 were non-different except T3 (P<0.001). In conclusion, DCfCaP could substitute concentrate up to 33% in the diet without being effective in Thai native x Lowline Angus crossbred cattle. Therefore, DCfCaP is recommended because it is an alternative source of animal feed and could contribute to controlling environmental contamination. So DCfCaP is recommended to supply to cattle.
