Published: June 2022

Abstract
Biodegradable foam (biofoam) packaging is a prospective packaging material that could developed from starch. Canna as a starch sources tuber of 93.30% consist of amylose content of 42.40% and amylopectin 50.90% is not utilized optimally. Nevertheless, starch-based foams are brittle, hydrophilic and rigid. Natural fiber-based material such a rice straw could be added as a cavity filler; thus, obtained a strong and sturdy product. The method used for producing biofoam was the baking process at a temperature of 170°C for 15 minutes. The aim of this study was to determine the effect of canna starch and rice straw fiber proportion on biofoam quality. The formulations used between canna starch and rice straw fiber were 4:0, 3:1, 2:2, and 1:3. Treatment with a ratio of 2:2 showed the best biodegradability for an average solubility and degradation of 18.900% and 82.693%, respectively. Meanwhile, the density parameter obtained from treatment with ratio of 1:3 of 0.225 gr/cm3 as the lightest density due contains more straw fiber. The results of the SEM test showed that the dough was not homogeneous, and no cavity formed in the biofoam structure. In addition, the results of the FTIR showed there was not alteration in the compound content from biofoam produced.

Abstract
A study was carried out at the University of Zimbabwe Farm, to assess and quantify the correlation between plant canopy height and biomass in the rangelands of Zimbabwe. Two range sites, bush grassland and grassland, were selected and three paddocks within each range site were sampled. Four 25 m long transects were drawn in the four cardinal directions from the paddock center. Five 0.25 m2 quadrants were located at 5 m intervals on each transect line. Common plant species in both bush grassland and grassland range sites were Sporobolus pyramidalis, Hyparrhenia filipendula, Cynodon dactylon, and Eragrostis curvula. There was a significant (P<0.05) linear relationship between plant height and biomass for both range sites. There was a significant (P>0.05) quadratic relationship between plant height and biomass for grassland but not for the bush grassland. Pearson Correlation Coefficient (r) was 0.929 for grassland and 0.717 for bush grassland. The regression equation was y = 15.82x – 0.02x2 for bush grassland and y = 15.88x – 0.27x2 for grassland. The coefficient of determination (r2) for grassland was 0.863 and 0.514 for bush grassland. Variation in plant height explained 86.3% of the variation in biomass for grassland and 51.4% for bush grassland accordingly.
A comprehensive review on power tillers usage – bottlenecks and prospects in India
Authors: R Krishnadas , R Renganathan 
Published: June 2022

AbstractAgriculture mechanization is essential to increasing agricultural productivity and lowering production costs via timely agricultural operations.. The vast majority of farmers in India (86 percent) are small and marginal. Due to their limited financial resources, they are unable to acquire heavy machinery like tractors and tractor-drawn implements. Power tillers, on the other hand, are less expensive and more adaptable tools that may be used for a wide range of farm tasks. Since power tillers are more suited to small-scale farms than tractors, they have been a key component of the plan. Plows and dry-tillage machines, as well as weeding and intercultural tasks, pesticide application (such as spraying and dusting), crop harvesting (such as thinning), and post-harvest handling (such as bagging) may all be accomplished with the help of power tillers. It is easy to maintain, and the operator does not require any special training to fix it on the spot. A variety of external attachments are available, or can be constructed, depending on the nature of the task at hand for the purposes of creating a realistic picture of India’s power tiller market and examining previous studies on the topic, this research was carried out to determine the current state of the power tiller in India and to determine the potential for growth in the future as well as any obstacles that may stand in the way of widespread adoption. The study shows that a power tiller can accomplish agricultural chores in a timely way, with higher production and less drudgery, thanks to its adaptability.

Abstract
The goal of the retrofit at Zamrud substation is to transform a 28 MVA power transformer’s neutral point grounding system from direct grounding to grounding using a 20 Ohm Neutral Grounding Resistor (NGR). The amount of short-circuit current produced will fluctuate with the installation of NGR. It is necessary to re-setting the Ground Fault Relay (GFR) on Zamrud substation. To estimate the value of the short-circuit current after installing the NGR, the impedance matrix approach is used to calculate it. According to the results, LG’s largest short-circuit current is 397.83 A and its smallest is 313.55 A. Meanwhile LLG has a maximum short-circuit current of 5.334.30 A and a minimum short-circuit current of 943.31 A. Therefore, after NGR installation, the value of the relay setting is as follows: GFR pickup current on the transformer grounding GFR relay is 234.29 A, GFR pickup current on the neutral feeder 1 is 19.96 A, GFR pickup current on the neutral feeder 2 is 30.42 A, and GFR pickup current on the neutral feeder 3 is 38.40 A.

Abstract
For decades, Indonesia’s Economic Development had achieved great high growth rates by using more labor input, capital investment, physical and human, and fostering competition. Over time, Indonesia’s energy intensity, which historically always been high compared to other industrialized economies. This study aimed to analyze decomposition factors of energy consumption by analyzing the link between the other nine factors and household energy use. The Logarithmic Mean Divisia Index were used to identify the determinant variables that drove a household’s energy usage. This study used a Time-series VECM model for prediction model analysis. The Logarithmic Mean Divisia Index (LMDI) and decomposition index were used to identify the determining technological, economic, and social factors driving a household’s energy consumption evolution. We analyzed the outcomes after applying the LMDI. We provided econometric individual time series VEC models, which we used for three targeting models: social, economic, and technical factors. We discovered that economic variables were the most significant factors that aggravated the change in household energy consumption based on LMDI. Technical factors, on the other hand, were the lowest. We found that the government might reduce its energy use over time by improving technological factors. Energy efficiency had been a cornerstone in managing growing energy use. The declining relevance of fewer labor-force in the previous decade was reflected in the negative indication of social factors at home. We discovered that the models were more stable while using Time Series VECM.

AbstractSocial forestry is one of the programs delivered by the Indonesian government to distribute forest ownership to society. The program consisted of village forest, customary forest, community forest, a people forest plantation, and partnership for forestry. This study merely focused on the community forest in Indonesia. The purpose of this research is to analyze the context and problems during the implementation process of permit delivery for community forests in Gunungkidul, Yogyakarta, Indonesia. A qualitative method was used in this research to understand the case of community forests in the study site. Data were collected using an interview, non-participant observation, and secondary document. We find that many groups of farmers have not received the permit for forestry management because of regulatory constraints. The problems are induced by many policies in the forestry sector regulating various forms of forest management permits contradicting the principle of the decentralized forest management policy. We recommend to the government to simplify the process of forest permit management, especially for the community forest.

Abstract
Oil palm has become the main plantation commodity in Riau Province, Indonesia. As the province with the largest oil palm plantation at around 2.7 million hectares, Riau Province has 19% of Indonesia’s total oil palm plantation area. In the midst of environmental issues such as forest fires or using hazardous chemicals, companies or individuals who own oil palm plantations are trying to obtain sustainability certification from the Roundtable of Sustainable Palm Oil (RSPO). However, many companies have not obeyed the correct principles and criteria for sustainable palm oil production, especially in the perspective of using pesticides in oil palm plantations. Based on those problems, this study was to carry out an in-depth examination of the data available from the Plantation Office and Environment-Forestry Office of Riau Province. As a result, we discovered that 70% of the pesticides used were classified as hazardous pesticides, according to the World Health Organization (WHO). In addition, it was also found that oil palm companies used glyphosate and paraquat as the active ingredient in pesticides, which have been banned in many countries due to environmental issues. By this finding, the commitment of oil palm companies to achieve sustainable agriculture in using appropriate and environmentally friendly pesticides needs to be questioned‥

Published: June 2022

AbstractCrude Palm Oil (CPO) manufacturing in palm oil processing plants produces by- products known as palm oil mill effluent (POME). POME can improve the physical and chemical properties of the soil because it contains nutrients N, P, K, Mg, and Ca. One of the companies that have processed and utilized POME is PT X, Lampung Province, Indonesia. This study was conducted to analyze the strengths, weaknesses, opportunities, and threats (SWOT) of the effect of using POME on oil palm plantations for waste quality, physical soil conditions, soil chemical conditions and productivity of oil palm plants. The methodology of the research was using descriptive statistical methods of the secondary data and SWOT analysis. The results showed that the palm oil effluent applied in the PT X complied with the national quality utilization and waste management standards. The POME application has a beneficial effect on soil conditions. The involved area had higher pH, N, P, K, Ca, and Mg than control, but C- Organic and CEC in the application area were lower. Furthermore, the application of palm oil effluent tends to increase crop productivity in a range of 7.57 - 63.23%. The primary strategy obtained from the SWOT analysis is that it is necessary to conduct an intensive assessment and to implement appropriate and proper management and application. This recommended strategy is to get the value of the application of palm oil liquid waste suitable for a long-term sustainable waste application for soil and plants to improve the physical and chemical properties of the soil optimally.
