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. Key words: Cassava, cow manure, growth, IBA, NAA, yield

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

Background: Energy demand continues to increase along with population growth and human activities, while the availability of fossil energy in Indonesia is becoming increasingly limited. On the other hand, agricultural biomass wastes such as cassava stems, bamboo stems, coconut shells, and corn cobs are abundantly available but have not yet been optimally utilized as alternative energy sources.Aims: The aim of this research is to to evaluate the effect of combining biomass wastes of cassava stems, bamboo stems, coconut shells, and corn cobs using tapioca starch as a binder on the physical characteristics and energy value of biobriquettes, as well as to assess their conformity with briquette quality standards as an alternative fuel.Methods: This study produced biobriquettes from cassava stems, bamboo stems, coconut shells, and corn cobs using tapioca starch as a binder with two concentrations (7% and 10%). The biobriquettes were evaluated for physical and energy characteristics, including density, moisture content, compressive strength, shatter resistance index, calorific value, and burning rate, following SNI 01-6235-2000.Result: Evaluation of biobriquette quality based on SNI 01-6235-2000 shows that all treatments meet the requirements for density, moisture content, and Shatter Resistance Index, indicating good physical quality and mechanical durability. For calorific value, only treatments P2T1, P2T2, P3T1, and P3T2 meet the minimum SNI standard (? 5,000 cal/g), while P1T1 and P1T2 do not. Overall, the biobriquettes produced have the potential to comply with SNI 01-6235-2000 as an alternative fuel, although optimization of biomass composition is still needed to improve calorific value.Conclusion: The combination of cassava stems, bamboo stems, coconut shells, and corn cobs using tapioca starch as a binder was able to produce biobriquettes suitable as an alternative fuel. Treatments P2 and P3, particularly with a 7% binder concentration, met the calorific value requirement of SNI 01-6235-2000, indicating that a lower tapioca binder concentration is more effective and has strong potential for development as a renewable energy source based on biomass waste.

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

Corn (Zea mays) production generates a significant amount of agricultural waste, particularly corn stalks, which are often underutilized and may cause environmental problems if not properly managed. This study aimed to evaluate the performance and ergonomics of a slicer-type biomass chopper in processing corn stalks. The experiment was arranged using a completely randomized factorial design with two factors: machine rotational speed (1500, 2000, and 2700 rpm) and the number of input stalks (4, 5, and 6 stalks), with three replications for each treatment. The observed parameters included working capacity, fuel consumption, specific fuel consumption, losses, and ergonomic aspects. The results showed that the treatments significantly affected all observed parameters. The highest working capacity was obtained at treatment R3M6 (791.2 kg/h), while the lowest fuel consumption and specific fuel consumption were found at R1M4. The lowest losses were observed at R2M6 (1.118%). Overall, treatment R3M6 demonstrated the best performance by providing a balance between high productivity and acceptable fuel efficiency. Ergonomic evaluation indicated that the machine could be operated adequately, although higher operational levels may increase operator workload. Therefore, the slicer-type biomass chopper has strong potential for improving the utilization of corn stalk waste in a more efficient and sustainable manner.
