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 1) Implementing good governance as a challenge and solution to food security; 2) Food security stability also affects price and distribution policies; 3) Increasing rice production will make a major contribution to rice production. Superior rice varieties will increase food security and reduce poverty; 4) Food distribution is still not optimal so that availability in each region and prices in each region vary.

Abstract

Former nickel mine lands often have low soil quality and do not support the growth of revegetation plants. This study aims to evaluate the effect of humic substances and compost on improving the quality of post-nickel mine soil and plant growth media. The experiment was conducted using a completely randomized design in a factorial pattern with three levels of humic and compost treatments, as well as a combination of both, applied to nickel post-mining soil. The results showed that the addition of compost significantly increased the cation exchange capacity (CEC) and availability of nutrients (Ca, Mg, K, Na) in the soil. The addition of humic materials had relatively no significant impact on increasing CEC, but could increase phosphorus levels in the soil. In addition, compost and the combination of compost with humic materials can reduce available heavy metal Cr, although it causes an increase in Ni heavy metal levels in the soil. The results of this study make a significant contribution to the rehabilitation of ex-mining land in a sustainable manner, especially the use of humic materials and compost as a strategy to improve soil quality and increase agricultural productivity. The use of these organic materials is proven to be effective in improving the physical, chemical and biological properties of degraded soils, so it can be a more environmentally friendly approach compared to the use of synthetic chemicals

Abstract

The Cirata Reservoir, an important water reservoir in West Java, plays a key role in hydropower generation, irrigation, and flood control. However, increasing sedimentation poses a significant threat to the reservoir’s functionality. This study maps the bottom topography and evaluates flood risks from sedimentation through bathymetric mapping and water level rise simulations. Data was collected from 22 sampling points using Deeper Sonar Pro+, providing precise depth measurements. Depths ranged from 2.1 m to 45.9 m, with an average of 22.4 m and a standard deviation of 13.46 m. The deepest areas are located in the center and near the Citarum River, while shallower areas are found at the estuaries of the Cibalagung and Cisokan Rivers due to sediment deposition. Simulations of water level rise using bathymetric and NASADEM data showed that a rise of up to 15 m would inundate the western, southern, and southwestern regions of the reservoir. Although the total volume of the reservoir is not determined, these findings underscore the need for effective sediment management to sustain the reservoir’s capacity and ecological functions. Further studies are required to estimate the reservoir’s volume and model long-term sedimentation risks to support the Cirata Reservoir's sustainability.
