Abstract

Edamame grade is determined based on edamame quality parameters with several parameters that are quite a lot. The process of deciding edamame grade is relatively complicated and challenging. To determine the edamame grade, an experienced expert in the field is needed. With limited grading experts, the design of expert systems for grading edamame can help users or companies to determine edamame grade. This study aims to design an expert system for determining edamame grade, which can determine the quality of edamame accurately. The Design of an expert system in this research uses the forward chaining method. The stages of designing an expert system include problem identification, knowledge acquisition, building a data flow diagram, compile the database, building a decision tree diagram, and developing a user interface. The results showed that the expert system has been verified and validated well. Verification test results show that all the menu buttons on the expert system application are functioning correctly. Then, the validation results also show that the edamame quality output produced by the expert system is compatible with the expert solution, meaning that the expert system's output data is by following with the results of the decision given by the expert. In testing the validation of determining the quality is appropriate. The results of the verification and validation of the edamame grading expert system show that the expert system has produced satisfactory outcomes. Expert system output is compatible with the solution provided by the expert.

Abstract

Viral Nervous Necrosis (VNN) disease is one of the major causes of failure in grouper aquaculture activities. The pathogens attack the central nervous system, eyes retina, and reproductive organs. When the rainy season starts, it may generate lower water quality for aquaculture, which becomes a suitable condition for VNN infections in fry cantang grouper. For this reason, there is an emerged need to do the detection of the existence of Viral Nervous Necrosis (VNN) pathogen fry cantang grouper cultured at the rain season. Data analysis was carried out in descriptive ways that aim to make data are presented by the actual situation without giving any treatment so that it can be easily discussed with existing theory to conclude. The examination on the presence of Viral Nervous Necrosis (VNN) disease on fry cantang grouper lived at rain season was conducted using two methods which are conventional PCR and Real-time PCR. From 20 samples of fry cantang grouper taken for this study, 5 samples were detected positive Viral Nervous Necrosis (VNN) its equal to the prevalence of 25%. Histopathological observation on fry cantang grouper infected Viral Nervous Necrosis (VNN) show the appearance of vacuoles on ganglion cell layer, inner nuclear layer, and pigment epitel, a sign of lysis on the liver, vacuoles on the brain, necrosa, and hypertrophy on the brain, and the appearances of melano macrophage center on the kidney. The average water quality in the pond was reported at the temperature of 29.2 0C, salinity 33 ppt, and pH 8.3

Abstract

The purpose of this study was to determine the effect of giving golden snail meat flour in broiler rations aged 2-5 weeks to the appearance of broiler chickens and to find out what level of golden snail meat flour can give the results of body weight gain, final body weight, feed consumption, and conversion best ration. This study used a Completely Randomized Design with 5 treatments and 3 replications for each treatment. The five treatments were rations without the content of golden snail meat flour as control and rations containing golden snail meat flour 5%, 10%, 15%, and 20%. The parameters observed were bodyweight gain, final body weight, feed consumption, and FCR (Feed Conversion Ratio). The data obtained were analyzed by analysis of variance. If between treatments showed a real difference, then proceed with Duncan's test. The results of the study of the addition of golden snail meat flour (Pomacea canaliculata) in broiler chicken rations had a very significant effect (P<0.01) on the research variables' weight gain, final body weight, and lower FCR. Whereas the consumption of rations had a significant effect (P<0.05). In treatment R2 (10%) gave better results than other treatments (R0, R1, R3, and R4). This means that the treatment of giving golden snail meat flour in the ration apparently can increase the weight gain of broiler chickens. This is because the golden snail contains quite high protein. From the results of this study, it can be concluded that the administration of golden snail meat flour (Pomacea canaliculata) in broiler rations has a very significant effect on increasing weight gain, final weight, and decreasing FCR and significantly influencing ration consumption.

Abstract

Maize is the primary food resource for livestock, mainly cultivated in the northern mountains, the central provinces, and the central highlands in Vietnam. By studying reliable reports and policies related to maize-based agricultural production in combination with interviews and focus group discussion methods conducted in Son La province, this study specifically analyzes the situation of maize production in Vietnam and impacts of policies for the specific case in Son La province. The research results show that, though the sharp decrease, maize has still been the main crop with an annual cultivation area of ​​over 30% of the country's agricultural land recently. However, maize is only modestly mentioned in some central policies, and no policy at the local level is reserved for maize production. In addition, maize is no longer a crop to attract local farmers’ and authority’ interest, especially since 2015, the transition in maize cultivation area on sloping land to arable land of fruit trees and many other crops has been carried out on a large scale due to some policies by the province, resulting in a sharp decrease in maize cultivated area and production. This might lead to limited results of substantial government policies on maize acreage expansion, maize cultivated area planning, or maize development strategy. Accordingly, some recommendations to improve the situation are provided.

Abstract

Payment for Environment/Ecosystem Services (PES) is a market-based approach toward the dual goal of poverty alleviation and forest conservation. In Vietnam, PES has been nationwide applied to the forest environment, namely Payment for Forest Environmental Services (PFES). Nevertheless, the PFES application in forest-based tourism is very limited. To enhance policy implementation in practice, this study analyses a case study in Sapa town, Vietnam. We find that the overlapping revenue of service providers is a substantial issue holding back PFES applications in tourism. Accordingly, we recommend two potential payers for tourism-PFES, including accommodation companies and ticketing companies (based on the revenue from entrance tickets). We then suggest a PFES payment level of 1 percent of total revenue from ticket sales and room charges. Moreover, the study also provides some recommendations to ensure the fairness and transparency in PES application, as well as factual, reflect of the nature of PFES during implementation.

Abstract

The problem for farmers in Suruh Village is having two types of farming which are cacao-goat integrated system farmer and cacao-goat non-integrated system farmer. Cacao-goat integrated system conducts cacao farming with goat livestock while for the cacao-goat non-integrated system does not conduct goat livestock. Farmer's interest is different in conducting cacao farming system. The aim of cacao-goat integration system is obtaining manure as organic fertilizer by the expectation to save fertilization cost so that farmer's income with the cacao-goat integrated farming system will be different with non-integrated one because seen from the maintenance cost because of manure. In this study, we dig pattern analysis information of the cacao-goat integrated farming system to find out cacao-goat integrated system and income difference of cacao-goat integrated and non-integrated systems so that it aims to find out the pattern difference of cacao-goat integration farming The research result shows that cacao-goat integrated system by the utilization of cacao waste (bark, leaf), intercropped plant (avocado, cassava, stink beans) as the animal feed of goat). Goat livestock produces feces that can be used as cacao compost fertilizer after 12 months of fermentation. The average income of the cocoa-goat non-integration farmer is USD 1,184.91/Ha/Year, while for the cocoa-goat non-integration farmer has the average income of USD 854,673/Ha/Year. There is a significant difference between cacao-goat integrated farming income and cacao-goat non-integrated farming income.
