Abstract

Oil palm has the prospect of rapid development in Indonesia, which causes an increase in plantation area to continue. However, the problem that is still encountered is the low productivity and quality of crop production. The solution that can be used is the use of planting material derived from superior varieties. High-yielding varieties are assembled through hybridization of two varieties that have the desired superior properties. Observation of the flower development cycle is needed as the basis for the hybridization process. Flower development is not only influenced by genetic factors, but also by environmental factors, especially climate. Observations on plant responses are part of a phenological study. This research was carried out in April-August 2021 at Pabatu Gardens, PTPN IV with the aim of observing the flowering phenology of the DxP 540 NG and DxP Socfindo MT Gano varieties. The climatic conditions of the research location during the observation were an average temperature of 29°C, 80% humidity, and an average rainfall of 145 mm/month. The average time required for the DxP 540 NG variety of male and female flowers, the growth phase of the sheath until the outer sheath broke, was 40 days and 38 days, the outer sheath broke until the inner sheath burst was 15 days and 18 days, the inner sheath broke to full bloom was 12 days. days and 16 days, and in full bloom until the flowers are completely pollinated, namely 4 days and 6 days. The average time required for the DxP 540 NG variety of male and female flowers in the growth phase of the sheath until the outer sheath breaks are 32 days and 30 days, the outer sheath breaks until the inner sheath bursts are 16 days and 15 days, the inner sheath bursts to full bloom, namely 11 days and 15 days, and in full bloom until the flowers are perfectly pollinated, namely 4 days and 6 days. The total time required for flowering for the male and female DxP 540 NG varieties was 71 days and 78 days, while for the DxP Socfindo MT Gano variety, male and female flowers were 63 days and 66 days, respectively.

Abstract

Plantation of PT. Tidar Kerinci Agung (PT. TKA) is a company engaged in oil palm plantations with an area of 24,000 ha and has been certified by Indonesia Sustainable Palm Oil (ISPO). PT. TKA has a factory for Crude Palm Oil (CPO) processing, therefore the local community can sell their palm oil yield to the factory. However, the purchase of Fresh Fruit Bunches (FFB) from the community was constrained by the fact that many people use random seeds which reduce the quality of CPO, moreover the agronomic factors such as fertilization, rainfall, plant maintenance and harvesting on smallholder plantations which are the factors that can reduce the quality of CPO. The present study was conducted for 3 months, with the objective was to determine the comparison of the palm oil extraction rate between smallholder plantations and large-scale estate (PT. Tidar Kerinci Agung). The research method was a survey by purposive sampling to obtained data on oil palm production, especially in relation with oil extraction rate. The result showed that the oil extraction rate of CPO was 24.51% and it’s on Palm Kernel Oil (PKO) was 4.45% in large-scale estate (PT. TKA). It was higher than the oil extraction rate on smallholder plantations. The oil extraction rate of CPO and PKO in the high yielding, moderate yielding, and low-yielding smallholder plantations were CPO 20.55% and PKO 4.42%, CPO 21.50% and PKO 3.77%, and CPO 18.35% and PKO 4.34%, respectively.

Abstract

Ultisols are a marginal soil order which is widespread in Indonesia. However, due to the limitations the fertility of this soil, it is necessary to add organic matter beside inorganic fertilizers to support the growth of cacao seedlings. The objectives of this study were to determine the growth response of cacao seedlings due to the application of NPK and vermicompost fertilizers, as well as to determine the interaction effect and the best dosage of those fertilizers on the growth of cacao seedlings in Ultisols. This study was designed in a Completely Randomized Design (CRD) Factorial with two treatment factors. Treatment doses for NPK were 0 g/polybag, 0,5 g/polybag, and 1 g/polybag, while the doses for vermicompost treatment were 0 g/polybag, 12,5 g/polybag, and 25 g/polybag. Each of these factors was repeated three times, so 27 experimental units in total. Observational data were analyzed using analysis of variance and further analyzed by Duncan’s New Multiple Range Test (DNMRT) at 5% significance level for statistically significant results. The growth variables of cacao seedlings were seedling height, stem diameter, number of leaves, and leaf area index. The results showed that the best dose of vermicompost fertilizer to the growth response of cacao seedlings was 12,5 g/polybag. However, we found no interaction effect between NPK fertilizer and vermicompost to the growth of cacao seedlings in Ultisols

Abstract

Cacao plays an important role in the Indonesia economy. Therefore, its production and area expansion have to increase to achieve maximum cacao productivity by the quality and superior cacao clones. Shoot tip grafting is one of the propagation methods to obtain superior cacao plants by applying Plant Growth Regulators (PGRs). Research on the effect of several PGRs with various concentrations on cacao (Theobroma cacao L.) shoot tip grafting was conducted at the Integrated Innovation Farmer Group, Belubus, Sungai Talang Village, Guguak District, Lima Puluh Kota Regency, West Sumatra from February until June 2022. This study aimed to determine the interaction between PGR type and concentration on the grafting success and growth of cacao shoot tip grafted seedling. The research was designed by a Factorial Completely Randomized Design with three replications. The first factor was the type of PGR, i.e., synthetic PGR (BAP), young corn seed extract, shallot extract, and young coconut water. The second factor was the concentration of PGR, i.e., 0%, 25%, 50%, 75% and 100%. The results showed an interaction between PGRs with some concentrations on the number of shoots, shoot length, and leaf length on the grafted cacao seedling. The natural PGR from young coconut water at a concentration of 75% gave the best effect on the number of shoots (3.33 shoots) and shoot length (24.50 cm) of cacao seedling.

Abstract

It is necessary to redevelop cacao (Theobroma cacao L.) commodity due to the decrease of cacao planting areas in Indonesia since the last decade. One of the ways is by providing a growing medium to produce cacao seedlings with good quality, such as by adding ameliorant i.e., oil palm empty fruit bunch (OPEFB) biochar to marginal soil of Ultisols. This research aimed to study and obtain the best OPEFB biochar dose to improve the chemical properties of Ultisols and the growth of cacao seedlings. This research was conducted in the Experimental Field of the 3rd Campus Andalas University from August 2021 until February 2022 using a Completely Randomized Design (CRD) with 5 treatments of OPEFB biochar (0, 60, 90, 120, 150 tons/ha) and 4 replications, each experimental unit consisted of two plants, so that 40 plants were prepared in total. Data obtained were analyzed using F Distribution Test at 5% and further analyzed using Duncan’s New Multiple Range Test (DNMRT) for statistically significant results. The results showed that the application of OPEFB biochar at 120 tons/ha was the best dose to give significant results on the chemical properties of Ultisols (pH, organic carbon, total nitrogen, available phosphorus, exchangeable potassium) and several growth variables of cacao seedlings (stem diameter, leaf length, leaf width, shoot dry weight, and shoot-root ratio).Keywords: ameliorant, biochar, nursery, oil palm empty fruit bunch, Ultisols

Abstract

Aren palm (Arenga pinnata Merr) belongs to the palm tribe. The problem that is often encountered in aren palm plants is the low productivity of aren palm plants, this is allegedly because the seeds used are not superior seeds and cultivation techniques that are not yet appropriate. The low production of plants is thought to be due to the low knowledge of the community on the use of superior aren palm planting materials, where the cultivated aren palm is not considered superior properties, including the diversity of aren palm species that grow wildly is still high in one forest land, unclear identity of seeds used by farmers. Exploration is the first step in finding germplasm of aren palm plants that have the expected traits through breeding programs so that it is expected to be one of the solutions for the development of aren palm plants. This research will be conducted from May to October 2023 in community-owned aren palm plantations in 50 cities. The purpose of this research is to characterize the morphology of Aren plants in District 50 Kota and to see the level of diversity of aren palm plants in the area. The research method was survey method, with purposive sampling. The data collection technique is to observe the morphological parts of the plant in each sample. The data obtained were analyzed descriptively, while for the analysis of similarity the calculation of the NTSYS Ver 2.02 program was used. The results of the study obtained 4 clusters of palm plants from 3 villages namely Nagari Sungai Kamuyang, Sikabu-kabu and Mungo. Researchers obtained 15 samples of aren palm plants characterized by 19 characters, namely 10 characters have wide variability and 9 characters have narrow variability with a level of diversity ranging from 14% - 47%.
