Pengaruh berbagai dosis pupuk organik cair urin sapi terhadap pertumbuhan semai durian (Durio zibethinus Murr) di lapangan

Cow urine is an alternative to increase the availability, adequacy, and efficiency of nutrient uptake for plants containing microorganisms so that it can reduce the use of inorganic fertilisers (N, P, and K) and increase plant yields to the maximum. The application of liquid organic fertiliser must pay attention to the concentration or dose applied to the plants. This research aims to determine the effect of various concentrations of liquid organic fertiliser made from cow urine on the growth of durian seedlings. This research was carried out for three months, from February to May 2023, at the Arboretum of the Faculty of Forestry, Tadulako University. This research used a completely randomised design (CRD) method consisting of five treatments. M0 = control, M1 = (150 ml POC: 850 ml water), M2 = (200 ml POC: 800 ml water), M3 = (250 ml POC: 750 ml water), and M4 = (300 ml POC: 700 ml water). The five treatments were repeated six times, so the total experimental units were 30. The parameters observed in this research were the increase in seedling height, the increase in the number of seedling leaves, and the increase in seedling diameter. Research data was analysed using analysis of variance. Further tests were carried out using the Honestly Significant Difference (BNJ) test at the 5% level. The results of the variance analysis showed that the application of various concentrations of liquid organic fertiliser made from cow urine had a significant effect on the increase in height, the number of leaves, and the diameter of durian seedlings. Based on the results of the BNJ test at the 5% level, it shows that the average increase in seedling height, number of leaves, and diameter of durian seedlings in the M4 treatment was significantly different from the M3, M2, M1, and M0 treatments. The average increase in height of durian seedlings is M4 = 5 cm, M3 = 4.66 cm, M2 = 4 cm, M1 = 2.91 cm, and M0 = 2.08. Average increase in number of leaves: M4 = 4 pieces, M3 = 3.33 pieces, M2 = 2.66 pieces, M1 = 2.16 cm, and M0 = 1.83. Average increase in diameter: M4 = 1.21, M3 = 1.03, M2 = 0.73, M1 = 0.45, and M0 = 0.28

Tinjauan kebijakan penyediaan kawasan hutan untuk pembangunan food estate

The problem of food security in Indonesia has become an endless polemic from the era of President Soekarno's regime until now; providing food for all Indonesian people has still experienced many obstacles. Indonesia still needs help from other countries to meet people's basic needs by importing food from neighboring countries, such as rice imports from Thailand and soybeans, sugar, and garlic imported from foreign countries. Indonesia, as an agricultural country that should have a good level of food security, is still far from sufficient to meet food needs in its own country; this is what encourages the government to implement regulations that are expected to increase the level of food supply. The government has carried out various projects to answer challenges that continue to this day, from the Mega Rice Project in the Soeharto era to the formation of the Me-rauke Integrated Food and Energy Estate (MIFEE). In 2015, a 500,000-hectare food estate in Kalimantan was announced. In 2020, the issue of food security rose to the surface again due to the Covid-19 pandemic. This article explores the historical study of food estate discourse carried out by the government. It compares it with a critical review of the concept of food in Indonesia, the implementation of food estates, and food security from a literature review

Pelaksanaan good agricultural practices dan penerapan skema fair trade pada perkebunan kopi rakyat Jawa Tengah

The implementation of Good Agricultural Practices (GAP) on smallholder coffee plantations in Central Java is considered a solution that has the potential to increase coffee production while protecting biodiversity and achieving sustainable plantations. Several preliminary studies show that implementing GAP is directly proportional to the productivity of crops and prevents monoculture plantation methods, which are detrimental to the environment and productivity. Apart from that, another problem being addressed is the low welfare of coffee farmers in Central Java due to the low purchasing price of coffee and the dominant export in the form of raw coffee beans. This province can take steps by introducing a fair trade scheme for coffee farmers who are members of cooperatives or farmer groups. By implementing fair tradeprinciples, farmers' welfare can increase through equal welfare distribution between farmers and sellers, price transparency, new business opportunities, decent wages for workers, and environmentally friendly production and sales processes. Through analysis of the two problems above, this article aims to provide a deeper understanding of the importance of implementing GAP and fair trade schemes in increasing the productivity and welfare of coffee farmers in Central Java, as well as contributing to the development of sustainable and environmentally sound coffee plantations in Indonesia
