Abstract

The growth and production of cassava can be increased through various efforts, including the use of superior varieties, fertilization, the addition of organic materials, and the application of growth regulators (PGR). Naphthaleneacetic acid (NAA) and indole-3-butyric acid (IBA) are PGRs that have been widely documented to stimulate root initiation and development in cuttings. The application of aauxin mixtures on cassava cuttings followed by fertilization and the addition of organic materials is expected to improve the growth and yield of cassava. The aim of this experiment is to study the effects of the application of an NAA and IBA mixture (1:1) and the type of fertilizer on the growth and yield of the Garuda variety of cassava. This research is designed using a clustered randomized block method with three replications. The design used is factorial 2x3, consisting of two main treatment factors. The first factor is the combination of growth regulators NAA and IBA in a 1:1 ratio at three concentration levels, namely 0 ppm, 500 ppm, and 1,000 ppm. The second factor includes the type of fertilizer used, which is a single inorganic fertilizer and a combination of inorganic fertilizer with cow manure. Each experimental unit in this study consists of 10 cassava cuttings planted in an orderly manner with a planting distance of 1 meter x 1 meter between plants. The results of the experiment showed that the application of inorganic fertilizer produced plant growth and the number of productive roots equivalent to the use of inorganic fertilizer + cow manure. The application of a mixture of auxins NAA and IBA (1:1) at concentrations of 500 ppm and 1,000 ppm significantly increased the growth of shoots, the number and weight of productive roots of the Garuda variety cassava, but both treatments resulted in cassava growth and yield that were not different.

Abstract

Crude palm oil (CPO) productivity in Central Lampung Regency, at 2.25 tons/ha/year, remains below the national average of 3.90 tons/ha/year. One of the contributing factors is that oil palm plants are not growing optimally. This is reflected by the fact that the canopy cover is not dense or uniform. The objective of this study was to assess the dense or crown of oil palm trees using remote sensing technology from satellite imagery. In this study, Sentinel-2 imagery was used to oil palm canopy closure, and Landsat 8 imagery was used for land suitability analysis. The research method includes the vegetation index analysis by Normalized Difference Vegetation Index (NDVI), land moisture index by the Normalized Difference Moisture Index (NDMI), Land Surface Temperature (LST), and land suitability parameters. The results of the analysis are then macthed with the conditions of oil palm plants in the field. The results obtained from this study indicate that oil palm plantations in the Bekri District can be categorised into two discrete classes: Class S2 (sufficiently suitable) and Class S3 (marginally suitable). The total area encompassed by these classes is 8,903 hectares, with Class S2 covering 7,615 hectares and Class S3 covering 218 hectares. Moreover, the study revealed that 3,721 hectares were conducive to optimal plant growth with a dense crown, 765 hectares exhibited normal crown and growth, and 310 hectares displayed suboptimal growth with an indicated uniform dense crown. The overall accuracy rate of the study is 81.82%. There is a positive correlation between NDVI and NDMI values with a correlation coefficient (R2) of 0.8426, but there is a negative correlation between the NDVI and LST values with a correlation coefficient of -0.586.

Abstract

The utilization of technology in the agricultural industry is significantly growing recently. This is mostly due to its ability to enhance labor and land productivity, while simultaneously reducing production costs. The objective of this study is to examine the institutional performance and utilization of farm machinery (alsintan) by rice farmers, and to investigate the correlation between institutional performance and alsintan usage on the productivity and income of rice farmers. The study was carried out in two villages in the Central Lampung Regency, namely Rengas Village in Bekri District, and Trimurjo Village in Trimurjo District. Rice farmers in both villages actively utilized alsintan operated under the alsintan service unit (UPJA). The study findings indicate a strong and meaningful correlation between institutional performance and the utilization of alsintan with productivity and income level of tarmers. Alsintan technology directly impacted productivity and revenue with coefficients of 0.63 and 0.60, with confidence levels of 99.9% and 99.7%, respectively. Institutional performance indirectly affected them with a coefficient of 0.30 and a confidence level of 99.99%. The integration of enhancing institutional performance with the optimization of alsintan technology can foster the enhancement of other factors, such as human resource performance, group member involvement, and external environmental support. Keywords: Alsintan, Institutional, Optimization.

Abstract

Cassava is an important crop for carbohydrate production, primarily propagated through stem cuttings. Auxin has been proven for decades to be an effective material for increasing the rooting of cuttings. The combination of NAA and IBA is more effective than a single auxin and synergizes in promoting root growth. This study aimed to evaluate the growth and yield of cassava clones to different auxin concentrations of NAA+IBA mixture. The research used a randomized complete block design arranged in a factorial with 9 (3x3) treatments repeated 3 times. The first factor was the type of cassava clone, consisting of K1 = Garuda, K2 = Katsesart, and K3 = Roti, while the second factor was the concentration of NAA + IBA (1:1), namely A0 (0 ppm), A1 (1,000 ppm), and A2 (2,000 ppm). The results showed that clones responded differently to auxin concentration. Increasing the auxin concentration from 1,000 ppm to 2,000 ppm did not increase growth and yield, irrespective of clones. The application NAA + IBA (1:1) significantly increased fresh leaf weight, plant height, fresh stem weight, total number of roots, and number of storage roots as compared to the control at 8 months after planting (MAP). At 8 MAP, the Kasetsart clone produced higher growth and yield than Garuda and Roti clones, as indicated by the average plant height, total number of roots, and number of storage roots.
