Abstract

Avocado fruit with the Latin name Persea Americana Mill comes fromMexico and Central America. Avocado plants can grow to reach a height of 20 meters. The demand for and consumption of avocados continues to increase day by day. The more people demand avocado fruit, the more quality avocado seeds are needed. One way to get quality seeds is by vegetative propagation by grafting. Growth on shoot grafts can be accelerated by using Cytokinin growth regulators (BAP). The research was conducted in the Cipedak Avocado Plant Propagation Garden, Jagakarsa District, South Jakarta from January 2022 to March 2022. The research aims to determine the ef ectiveness of the concentration and soaking time of cytokinin growth regulators (BAP) on the growth of cipedak avocado shoots (Persea americana mill). The study was conducted using a randomized block design (RBD) consisting of 9 treatments with 3 replications, namely concentrations of 200 ppm, 400 ppm, 600 ppm, and control. From the results of the study, there was an interaction between concentration and soaking time on the percentage of live shoot grafting (%), percentage of fallen leaves (%), increase in shoot length, bud break age and rootstock diameter at 6 WAP, the ef ect of dosing and soaking time The optimum cytokinin zpt is in the S2T3 treatment.

Abstract

Source of Gross Domestic Product (GDP) for the Indonesian among other things that are important isfrom plantation sector. Export-oriented domestic plantation companies, their performance is determined by their productivity and is influenced by many internal and external factors. It is necessary to study role of investment inplantations on gross domestic product and on productivity. Investment policies are needed for sustainable longterm plantation development. This research was purposive by collecting secondary data on the annual time series of Indonesian plantations from 1990 to 2021, using the OLS linear regression data analysis method. The investment variable as an independent variable is regressed against two independent variables, namely plantation GDP and plantation productivity. The conclusion of his research is that investment in plantations has a significant effect and positive on plantation GDP and on plantation productivity. The findings obtained are that Investment plays a large and very strong role in the formation of Plantation GDP and Plantation Productivity and is predicted to take placeinthelong term effect. Further research is suggested to study more deeply the forms and sources of effectiveinvestment.

Abstract

In this study, the research aimed to determine the optimal combination of fermentation duration and material dosage for making turi liquid organic fertilizer. The study was conducted at the Laboratory of the Faculty of Agriculture, Borobudur University, and further tested at the Laboratory of the Department of Soil Science and Land Resources, Bogor Agricultural Institute. The research compared different combinations of fermentation duration and material dosage using five parameters: C-Organic, pH, N, P, and K. The results showed that the best combination was a fermentation time of 7 days with a 1:1 material dosage of turi leaf to brown sugar. This combination had a higher organic content compared to a fermentation time of 7 days with a 2:1 material dosage. Additionally, a fermentation time of 10 days with a 2:1 material dosage had a higher organic matter content compared to a 1:1 material dosage. Overall, a fermentation time of 7 days and a 1:1 material dosage were found to be the best for making turi leaf organic fertilizer
