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

Bee pollen is one of the popular bee products besides propolis and honey. It contains good nutrition for the body and has been used to boost nutrition as a fortification or substitution ingredient in various food preparations such as biscuits. This study aims to determine the effect of storage time on the physical characteristics of a substituted biscuit with bee pollen. The experimental design was a Completely Randomized Design (CRD) with one factor as the storage time of days 0, 2, 5, 7, 9, 12, 14, 16, and 19. The result showed that the storage time significantly influenced the texture and weight change of substituted biscuits with bee pollen while the water content was not significantly affected.

Abstract

In this study, we aimed to investigate which components of cassava (Manihot esculenta Crantz) would be associated with the cassava tuber weight when infected with the Sri Lankan Cassava Mosaic Virus (SLCMV). We conducted multiple regressions to find associations between other cassava elements and tuber weights. This study was carried out in the Rukhak Kiri district in Battambang Province, located in northwestern Cambodia, in March 2019. We assessed two major varieties used in the region, namely, KU 50 and Rayong 7, using 90 samples—60 samples of KU 50 and 30 samples of Rayong 7. The results showed that the tuber weight of KU 50 was heavier than that of Rayong 7. In addition, the biomass of the stem, that is, the weight of all branches and leaves, were the sole strong factors associated with tuber weight for both KU 50 and Rayong 7. Moreover, as the tuber number declined, the tuber weight declined rapidly for Rayong 7. Overall, we concluded that SLCMV infection affects the biomass weight of cassava.

Abstract

Papaya is one type of fruit that is widely consumed and cultivated by the farmer. However, genetic analysis has not been carried out on various types of papaya available on the market. This aims to determine the genetic diversity of papaya plants that can become genetic resources to fullfil food needs and genetic resources for breeders. Genetic analysis was conducted by Random Amplified Polymorphic DNA (RAPD) method using 11 papaya varieties consisting of Calina, Bangkok, Red Pomegranate, Sunrise, Orange Lady, Red Lady, Taiwan, Arum, Miba, Golden, and Local and using 15 RAPD primers consisting of OPA-1, OPA-2, OPA-8, OPA-16, OPC-4, OPC-11, OPC-13, OPC-20, OPD-20, OPE-2, OPE-6, OPE-11, OPE-14, OPM-6, and OPY-15. PCR-RAPD results were translated into binary data and then cluster analysis was conducted using the Unweighted Pair-Group Method Arithmetic (UPGMA) method using the Numerical Taxonomy and Multivariate System (NTSYS) program. The PCR-RAPD results of 11 papaya varieties successfully amplified 8 out of 15 primers that formed 112 DNA bands with 85 polymorphic bands. Genetic diversity analysis showed the results at 90% similarity coefficient formed 9 groups. Group 1 consists of Bangkok and Sunrise varieties. Group 2 consists of Red Pomegranate and Arum varieties. Groups 3 to 9 consisted of Calina, Miba, Local, Golden, Orange Lady, Red Lady, and Taiwan varieties, respectively.

Abstract

Sungai Suci is a part of Bengkulu that is 400 meters above sea level. Sungai Suci is located in a coral coastal area with three ecosystems: the bamboo ecosystem and the sea pine ecosystem; soil arthropods are among the animals that inhabit those two environments. This study aims to look into the variety of soil arthropods in the ecosystem of Sungai Suci. Sampling bamboo and sea pine ecosystems was done by taking soil from the root areas of bamboo and sea pine. For each ecosystem, five soil samples are taken randomly as replication. The soil was placed in a smaller funnel and left for two weeks at room temperature 24ºC, and 12 hours of irradiation. Soil arthropods obtained from the three ecosystems were identified, and their numbers were recorded. The most common type of arthropod found in the three ecosystems was acarina. The study results showed that the diversity values of the bamboo and sea pine ecosystems, respectively, were 1.44 and 0.49; and. Dominance values for the bamboo and sea pine ecosystems, respectively, are 0.38 and 0.82. The evenness values of the bamboo and sea pine, respectively, are 0.56 and 0.18.

Abstract

This study aimed to assess the effect of rice green folder on growth performance in Khmer native x Hariana crossbred cattle. Twelve males of Khmer native x Harian crossbred cattle were assigned an initial body weight of 190±10 kg (IBW) with 62 days of feeding regimen and an average of 15 months of age. The dietary treatments were assigned in a completely randomized design (CRD), with three treatments of four replications, each containing four cows. Feeding treatments were as follows: 1) 100% commercial feed (Control), 2) 50% commercial feed + 50% natural grasses (NG-50), and 3) 50% commercial feed + 50% rice green folder (RGF-50). Cows were fed at 1.5% Body weight of dry matter (DM). The results indeed showed that the initial body weight (IBW) and final body weight (FBW) were non-significantly different (P>0.05). The Control group consumed the total feed intake between the groups NG-50 at 6.58 kg and 6.85 kg, which were similar amounts but higher than RGF-50, which was 5.79 kg daily a head (linear increased <0.05). Nevertheless, average daily gain (ADG) in Control, NG-50, and RGF-50 was linearly increased (P<0.05) as the ADG was 0.58, 0.46, and 0.39kg/head. FCR in the NG-50 and RGF-50 were in the same row and higher than Control, with the precious value in both NG-50 and RGF-50 at 14.90 higher than 11.45 Control (P<0.001).  In conclusion, RGF-50 was a suitable roughage supply for feedlot cattle and could improve economic effectiveness. Thus, RGF was recommended for further study.

Abstract

The percentage of the population living in poverty in Bengkulu Province was not affected by the pandemic and even tended to decrease. This is contrary to the findings of studies on the impact of the pandemic on income, poverty, and food security. One way to determine the impact of the pandemic on food security is by comparing the conditions before and after the pandemic. Based on the descriptive analysis results, the food Security Index in some districts increased steadily throughout the period, but others fluctuated. Some districts experiencing fluctuations include Rejang Lebong, Seluma, and Mukomuko. The Food Security Index of other districts, including Bengkulu City, tends to increase. Only the Food Security Index of Kepahiang and Bengkulu Tengah districts shows a tendency to decrease. The results of the paired sample t-test indicate a significant difference in the food security index among districts and cities in Bengkulu Province between before and after the pandemic. This finding aligns with the descriptive analysis results that show a difference in the food security index among districts and cities in Bengkulu Province. Further analysis was conducted by considering these three aspects. However, the three aspects yielded different results in the paired sample t-test. Only in terms of food quality, the paired sample t-test results showed a significant difference in quality index between before and after the pandemic, supported by a p-value of (0.032) < alpha 5%.
