The Effect of Giving Aloe Vera Growth Regulators to Entres on the Success of Grafting Honey Mango Seedlings (Mangifera Indica)

Umar Husein Abdullah — 2024-08-30

This study aims to influence the administration of Aloe vera Plant Growth Regulators (PGR) on scions on the success of grafting of Honey Mango seedlings with concentrations of 2, 4, and 6 grams. The parameters observed were: Plant height was measured using a ruler by measuring from the ground surface to the tip of the highest stem. Stem diameter was measured at a height of 1 cm above the ground surface using a digital caliper. The number of leaves counted were leaves that were fully open. The calculation of the number of leaves was carried out since two weeks after planting. Stem diameter measurements were carried out since two weeks after planting and then measured once a week for seven weeks. To see the factors that affect the Treatment (M0, M1, M2, and M3) on Plant Height, Stem Diameter and Number of Leaves, multiple linear regression was used. In addition to the PGR factor, factors such as weather, nutrients and soil type greatly affect plant growth (Saputro et al., 2017; Sipayung et al., 2024). It can be seen that the M3 treatment (6 grams of PGR) had a greater effect (50.7%) compared to the M0, M1, and M2 treatments. This indicates that the more plant growth regulators given to the plants, the greater the R square value. This is in accordance with the research of Prabawa et al., (2020) which stated that soaking natural plant growth regulators had a significant effect on the viability and vigor of expired pagoda mustard seeds, and the treatment of coconut water with a concentration of 50% (Z2) gave the best effect.

Response of Potato Growth And Yield On First Generation (G1) In Various Planting Media Compositions

Muhsanati Muhsanati — 2024-08-30

Potato is a horticultural commodity that contains carbohydrates, protein and other nutrients. Potatoes have the potential to be developed to support diversification and food security programs. This research aims to find out the suitable planting media, so that it can overcome the limitations and provide quality potato seeds. The research was conducted in March- August 2024 in Alahan Panjang, Solok. The treatments were several

compositions of cocofiber (CF) and cocopeat (CP) planting media arranged in a completely randomized

design with 6 treatments and 4 replications, namely the composition; CF 100%, CP 100%, CF 20%+CP

80%, CF 40%+CP 60%, CF 60%+CP 40%, and CF 80%+CP 20%. The data obtained were statistically analyzed using the F test and DNMRT further test at the 5% level. The results showed that in general the use

of 100% cocopeat plant media was the best composition, while Cocopeat 80% + Cocofiber 20%, gave the best

growth of plant height, number of leaves, stem diameter and number of branches

Correlation Analysis Between Watering Interval, Stem Height, Stem Diameter, And Number Of Leaves In Jackfruit Seedlings (Artocarpus Heterophyllus Lamk)

Umar Husein Abdullah — 2024-08-30

Meanwhile, the study entitled Correlation Analysis Between Watering Interval, Stem Height, Stem Diameter and Number of Leaves in Jackfruit Seedlings (Artocarpus Heterophyllus Lamk) is guided by the amount of watering of 100 ml which is based on the recommendation for the use of the best liquid fertilizer from the research of Mamik et al., (2020). The research will be carried out in the closed room experimental garden of the Plantation Management Study Program, Politeknik Indonesia Venezuela located in Cot Suruy Village, Ingin Jaya District, Aceh Besar Regency, from May 2024 to July 2024. The temperature in the experimental garden is set at 25^oC – 28^oC. To see the correlation analysis between the Watering Interval, Stem Height, Stem Diameter, and Number of Leaves in Jackfruit Seedlings (Artocarpus Heterophyllus Lamk) bivariate correlation analysis was used. There is a relationship between plant height, stem diameter, and number of leaves. There is no relationship between the length of the watering interval and the variables of plant height, stem diameter, and number of leaves. Table 6 shows that there are no variables that are strongly related and have a significant effect on the watering interval, plant height, stem diameter, and number of leaves. The decreasing amount of water causes plants to be unable to grow normally.

Chemical Content Study of Salak Sidimpuan (Salacca sumatrana Becc.) Fruit Based on Altitude

Rasmita Adelina Harahap — 2024-08-30

Salak can grow well in the lowlands at an altitude of 200 m above sea level to an altitude of 700 meters above sea level with a wet climate type. The desired environment has a pH of 5-7, rainfall of 1500-3000 mm per year with a dry season of four to six months. The purpose of this study was to determine the differences in soluble sugar content, vitamin C content and total titratable acid of Sidimpuan salak fruit (Salacca sumatrana Becc) based on the three classifications of altitude. This research has been carried out in West Angkola District in three locations with an altitude of 500-650m above sea level, Padangsidimpuan Hutaimbaru in 3 garden locations with an altitude of 400-500 m above sea level and South Angkola there are 3 with an altitude of 200-300 m above sea level, starting in August to September 2021. Based on the results of this study, it is concluded that the difference in altitude of the place does not significantly affect the dissolved sugar content and vitamin C of Sidimpuan salak fruit but the altitude of the place has a significant effect on the total titratable acid of salak fruit, namely 1.4011% in West Angkola and 0.9822% Padangsidimpuan Hutaimbaru sub-district and South Angkola 1.2644%.

The effect of applying liquid organic fertilizer Bamboo Shoots for Growth of Jackfruit Seedlings (Artocarpus heterophyllus lamk)

Sofia Keumalasari — 2024-08-30

This study aims to influence the administration of applying applying liquid organic fertilizer Bamboo Shoots on the success of grafting of Jackfruit Seedlings with a certain amount of concentration. This research used Randomized Block Design factorial with 5 treatments and 5 replications to obtain 25 experimental units with the order of treatment, namely N0 = No, Bamboo Shoot POC, N1 = Giving POC Bamboo Shoots 20 ml/seed, N2 =Providing POC Bamboo Shoots 30 ml/seed, N3 = Giving Bamboo Shoot POC 40 ml/seedling, and N4 = Giving Bamboo Shoot POC Bamboo 50ml/seed. The parameters observed were: plant height, number of leaves and

percentage of live plants. Plant height is measured by measuring from the basestems to the youngest shoots or leaves of growing plants using a ruler. The number of leaves is calculated by counting all the leaves which has developed and opened perfectly on the jackfruit plant which grow. Percentage of live

plants was carried out by counting the number of plants survival to the total number of plants planted. Observations were made at the age of 15, 30 and 45 days after plant. The research results show that the application of liquid organic fertilizer bamboo the best treatment obtained in N2 treatment (POC

bamboo shoots 30 ml/seed) aged 15 to 45 days after plant.
