EFEKTIVITAS PROGRAM KAWASAN RUMAH PANGAN LESTARI (KRPL) DALAM MENDUKUNG KETAHANAN PANGAN RUMAH TANGGA SELAMA PANDEMI DI KOTA KEDIRI
Get PDFThe KRPL (Sustainable Reserve Food Garden) program is an alternative in realizing food self-sufficiency to achieve food security during the Covid-19 pandemic. This study is to determine the impact of the KRPL program on household food expenditure patterns, food consumption patterns, and consumption levels by using a questionnaire interview method in 8 active KRPL groups in the city of Kediri with a total of 80 respondents. The result of this study indicates that as much as 70% of the harvest in process for the food and nutritional needs of the family, 38.75% think that the yields from their yards can meet their food needs. The yields of each KRPL are different due to several factors, namely, the area of land, the awareness of group members, the weather, and the desire of the members to plant types of plants. From the amount of harvest, it can be seen that the level of success of the KRPL program has a positive impact on household food consumption patterns. A yard or harvest yields are still dominant for household consumption. This condition supports the main concept of the KRPL program, namely to strengthen household food security

Pengaruh Harga Bahan Pangan Terhadap Inflasi Di Indonesia
Get PDFAbstractThis study aimed to analyze the effect of food prices on the development of inflation in Indonesia. Indonesia's inflation showed a declining pattern in 2017 to 2021. An analysis of the effect of food prices on inflation is needed to evaluate changes in food prices that cause and contribute to inflation. Food prices fluctuate in the midst of the Covid-19 pandemic in 2020 to 2021 because regional restrictions and mobility can affect the distribution process and availability of food ingredients. Food consumption had a fairly large proportion of total household consumption in developing countries, so changes in food prices would have an impact on economic conditions through demand and supply mechanisms. The analytical method used was multiple linear regression. The data used in the multiple linear regression analysis was secondary data consisting of food prices, namely rice, chicken meat, beef, chicken eggs, shallots, garlic, red chilies, cayenne pepper, cooking oil, granulated sugar and inflation for the July period. 2017 to July 2021. The results of the analysis explained that food ingredients shallots, rice, beef, and cooking oil had a significant effect with a negative coefficient direction on inflation, namely deflation tends to occur in food price movements. Garlic, chicken meat, and sugar had a positive effect on increasing inflation.Keywords: Price, Inflation, Commodit
