Abstract

Rice Blast has been known as the main disease on paddy which has high severity leading to economic loss. Exploring rice resistance can be an effective way to improve productivity and prosperity toward this staple crop. This study aims to determine several local varieties which have potential for productions and resistances. This study used factorial randomized block design (RBD) consisting of 2 factors including plant spacing (25 x 25 cm; 25 x 30 cm; 25 x 40 cm); Upland rice variety MSP 17, Sigambiri Merah, Hamparan Perak and Kambiri Lumat. The results of the study reveal that variety has a significant effect on disease intensity especially Sigambiri Merah but not on Kembiri Lumat. However, there is no significant effect of spacing on blast intensity except in grain weight. Conclusion of this research was the varieties (V) selection of red upland rice is the best strategy to improve rice resistance toward blast disease. Keywords:  Disease density, Paddy, Staple Crop.

Abstract

Indonesia is a country that has a very large water area which is a large potential resource to be utilized for national development. This condition affects the strong weak economic activities of the village. The purpose of the study is to find out how much the income of labor fishermen in Tebing Tinggi Village, Tanjung Beringin District, Serdang Bedagai Regency and to find out what factors affect the income of labor fishermen in Tebing Tinggi Village, Tanjung Beringin District, Serdang Bedagai Regency. This research was conducted in Tebing Tinggi Village, Tanjung Beringin District, Serdang Bedagai Regency, North Sumatra Province. This location was chosen intentionally (Purposive). The population in this study was 546 labor fishermen, the determination of the sample in this study used Arikunto's theory, namely if the total population was less than 100 people, then the number of samples was taken as a whole. But if the population is larger than 100 people then it can be taken 10-15% and 20-25% of the total population. The samples in this study were taken as much as 10% of the total population, so the number of samples in this study was 55 labor fishermen. Data collection techniques use primary data and secondary data, data analysis techniques in research use income analysis and multiple linear regression analysis. The results of the research on the working capital costs of labor fishermen amounted to Rp. 244,894/month, with an income of Rp. 4,128,386/month with an average of 12 trips a month of fishing. The results of multiple linear regressions that the working capital variable and the catch variable have a significant effect on the income of labor fishermen while the time variable at sea and experience variables do not have a significant effect on the income of labor fishermen in Tebing Tinggi Village, Tanjung Beringin District, Serdang Bedagai Regency.

Abstract

The high population will have an impact on the food crisis and poverty if it is not balanced with food security. The Indonesian government must be able to formulate a national food policy that can improve food security. The food policy includes the availability of food Supplies in good quantity and quality as well as affordable food prices by the community and safe for consumption. The purpose of this study is to examine the synergy of the national food security system. This type of research is qualitative research with the aim of explaining the phenomenon by reviewing existing data. Data sources are obtained through bibliographic data from manuscripts obtained from Google Scholar and analyzed using the Systematic Literature Review (SLR) which is a method that uses previous evidence-based evidence through reviews, evaluations, structured evaluations, classifications and categorizations. Based on the results of the review, the results of this study include: implementing good governance as a challenge and solution to food security; food security stability also affects price and distribution policies; increasing rice production will make a major contribution to rice production. Superior rice varieties will increase food security and reduce poverty; food distribution is still not optimal so that availability in each region and prices in each region vary.

Abstract

This research was conducted with the aim of determining the vitamin content, micro-macro nutrients, and physicochemical properties contained in the leaves of the Surat Dibata plant (Macodes petola). The analysis procedure included qualitative and quantitative vitamin tests using the DCPIP method and UV-Vis spectrophotometry, analysis of micro-macro nutrients using AAS, and measurement of water content, ash, pH, and water-soluble organic compounds based on the AOAC standard method. The test results showed that qualitatively these leaves contain vitamins C, B1, and E, with concentrations (mg/100 g) of 47.8; 1.02; and 0.99, respectively. Meanwhile, for micro-macro nutrients such as Fe, Zn, Mg, and Ca, quantitative results showed levels (mg/kg) of 47.2; 30.7; 212.3; and 433.7, respectively. Furthermore, the detected water content was 79.22%, the ash content was 10.15%, the pH was 5.8, and the water-soluble organic compound content reached 66.6%. Overall, this data shows that Surat Dibata leaves have great potential as a natural source of nutrients and phytochemicals that support the development of herbal products and environmentally friendly agriculture.

Abstract

This study, entitled Identification of Secondary Metabolite Compounds in the Stems and Leaves of Surat Dibata (Macodes petola) Using Gas Chromatography Mass Spectrometry (GCMS) aims to determine the compounds and their concentrations of secondary metabolites present in the stems and leaves of Surat Dibata (Macodes petola) using Gas Chromatography Mass Spectrometry (GCMS). The methods used in this study include maceration extraction to identify secondary metabolite compounds and Gas Chromatography Mass Spectrometry (GCMS) to determine the concentrations of these compounds in the stems and leaves of Surat Dibata (Macodes petola). The results of the study showed that the extraction identified secondary metabolite compounds such as steroids in the stems and flavonoids, steroids, and tannins in the leaves. Based on the results from the GCMS analysis, the stems were found to contain 0.63% steroids, while the leaves contained 0.002% flavonoids, 0.002% tannins, and 2.215% steroids.
