Abstract

Indonesia is facing the problem of low productivity of cattle. To increase the productivity of cattle producer, it can actually be done by relocating the cattle to the comfort zone by observing the physiological response. The purpose of this research is to evaluate the effects of misting cattle’s environment by using water sprinkler on the physiological response and the microclimate of the cattle’s shed. The design used was a paired T-test for physiological and microclimate response variables with 5 replications and a completely randomized design to determine the difference between body surface temperatures. The observations were conducted before water misting and after water misting. The results showed that treatment of misting water in the afternoon significantly decreased (P<0.05) the variables of cage temperature, humidity, temperature humidity index, rectal temperature, respiratory rate, and heart rate. Water misting in the afternoon in cattle produced a good effect on all physiological response variables. Keywords: beef cattle, pen microclimate, physiological responses, water sprinkler

Abstract

Sorghum is a multifunctional crop as a source of food, feed, and alternative energy. Plant breeding using the radiation mutation technique was applied to improve the characteristics of sorghum according to its purpose. This study evaluated the agronomic and fiber characteristics of selected sorghum mutant lines. Eight sorghum mutant lines were observed in this study (GHP-2, GHP-3, GHP-4, GHP-5, GHP-7, G-5, P-341, and P36.M10). Pahat and Bioguma sorghum varieties were used as control. Compared to eight selected mutant lines, Bioguma variety was the tallest plant. Except for P-341, all selected mutant sorghum lines produced lower plant biomass than Bioguma. The highest sugar content was produced by G-5 and P-36.M10. There are no significant differences in seed production per panicle. The lowest fiber fractions in the leaf and stem were produced by GHP-3 and G-5 mutant lines, respectively. Based on our findings, the P-341 sorghum mutant line can be used as forage sorghum because it produces high biomass and relatively low fiber content. The G-5 mutant line can be projected as an alternative energy source due to its high stem sugar content. Keywords: agronomy, fiber, mutant, sorghum

Abstract

In 2021, the realization of livestock transported by KM Camara Nusantara livestock ships only reached 67.73%, with the realization of shipping at 78.74%. Based on these conditions, this study aims to measure the effectiveness of implementing livestock ships and the factors that affect them. The method used was to calculate the weight of factors considered to affect using the Analytical Hierarchy Process. Data were obtained from questionnaires, interviews, and literature reviews. Respondents were stakeholders and users of livestock transportation vessel services, which include the NTB and NTT Provincial Livestock Offices, Bima Regency Livestock Office, the Ministry of Transportation, shipping operators, and business actors. The results are priority weights on benefit criteria (0.2648), number of livestock (0.2578), regulation (0.1716), and route (0.1541). Meanwhile, priority weights on the subcriteria of the number of livestock transported (0.2224), availability (0.1064), price disparity (0.0889), mileage (0.0677), and transportation socialization (0.0667). Based on the calculation of the weight of criteria and subcriteria, the effectiveness of implementing KM Camara Nusantara livestock vessels reached 78%, which is at the level of achievement that is quite effective. In general, to improve the effectiveness of KM Camara Nusantara livestock transport ship services, factors that need to get priority are the availability of transported livestock, the achievement of benefits, and supporting regulations. The subfactors that need priority are the number of livestock transported, availability, price disparity, mileage, and transportation socialization.

Abstract

Efforts to fulfill food consumption tend to pay little attention to ecosystem sustainability. Permaculture is an agricultural system that designs landscapes resembling natural ecosystems so that they can produce food and prioritize the principle of sustainability. However, as the population increases, permaculture must be reviewed to meet food consumption. This research is a case study in YS Permaculture that implements a permaculture farming system to meet the food consumption needs of the foundation's community. The purpose of the study is to identify the principles of permaculture in the empirical conditions of the foundation and formulate a development strategy to meet the food consumption of the foundation community. This research uses a qualitative descriptive method using an in-depth interview method with foundation management. Based on the identification of 12 permaculture principles, one principle still needs to be implemented optimally, namely, using and respecting renewable resources and their functions. Strategic steps that can be taken to increase the productivity of food commodities and fulfill food consumption are the extensification of permaculture gardens and the implementation of regenerative agriculture that integrates artificial intelligence, machine learning, and precision agriculture. The strategy of fulfilling food consumption for the foundation community through permaculture requires cooperation with various parties, including the government and academics, related to strengthening food security while still paying attention to environmental and social aspects. Keywords: environmental impact, food productivity, development strategy, permaculture, social impact

Abstract

Refined palm oil contains contaminants such as 3-monochloropropane diol ester (3-MCPDE) and glycidyl ester (GE) which are formed from diacylglycerol (DAG) and chloride (Cl) as precursors during processing. There is a need to control the levels of precursors especially during the bleaching stage using selected bleaching earth (BE). Reducing the number of precursors after the bleaching stage will minimize the formation of 3-MCPDE and GE in bleached palm oil (BPO) for the next refinery stage. The research consisted of three stages: (1) characterization of raw materials consisting of CPO, BE types 1, 2, 3, 4, and 5; (2) study on the effect of BE type; and (3) study on the concentration effect of selected BE for reducing DAG and Cl by chemical analysis of oil quality. The results showed that degummed palm oil (DPO) contained DAG of 6.70%, free fatty acid 5.66%, carotene 424.31 mg/kg, P 20.30 mg/kg, and Fe <0.021 mg/kg. The five types of BE have different physicochemical properties on which the effect will be seen on BPO. The second stage results showed that BE-4 was selected as the most potential BE. Using BE-4 of 2.5% was proven to reduce total Cl as 3-MCPDE precursors in the resulted BPO sample. The Cl level decreased to 3.05 mg/kg with the largest decrease percentage of 55.80% compared to DPO sample. BE-4 concentration of 2.5% has been able to withstand and prevent the increase of DAG as a precursor to GE contaminants during bleaching process. Keywords: 3-monokloropropanadiol ester, chloride, diacylglycerol, glycidyl ester, palm oil

Abstract

Limitations of cuttings become an essential problem in the expansion of cassava plantations. One strategy that can be taken is to reduce the length of the cuttings and increase the plant population to increase the area planted and produce more stems per unit area for the next growing season. This study aimed to determine the effect of cutting length and plant population per hectare on the growth and production of cassava stems. The research was carried out at the Jambegede Agricultural Technology Research and Assessment Installation in February–December 2020. The treatment consisted of two factors, namely three levels of cutting length (2, 4, and 10 buds/cutting) and three levels of the population (10,000, 30,000, and 40,000 plants/ha). The experiment used the Malang-4 variety and was applied to a completely randomized split-plot experimental design of three groups with the population as the main plot and the number of buds as sub-plots. The results showed that the number of buds/cutting increased the number of growing plants, one and three-month plant height, the number of viable stems, the length of unfit stems for seedlings, and decreased the percentage of dead plants. On the other hand, plant population/ha increases the percentage of dead plants, stem length unsuitable for seeds, and number of stems suitable for seeds. The interaction between the number of buds/cutting and the population was seen in the diameter of the three-month-old stems, the number of stems unsuitable for seedlings, the number of plants grown, the number of dead plants, and the number of plants harvested. Keywords: cassava, length of cuttings, number of buds, plant population, stem production

Abstract

Eco-enzymes are one of the potential sources for obtaining amylolytic bacterial isolates. The study aims to screen amylolytic bacteria from eco-enzymes, characterize semi-purification amylase, and identify amylolytic bacteria molecularly using the 16S rRNA gene. Screening for amylolytic bacteria was carried out by measuring the amylolytic index on a Nutrient agar medium containing 1% tapioca starch. The amylolytic isolate which had the highest index and was non-pathogenic was selected for the amylase characterization process. Testing of amylase activity was carried out using the Bernfeld method while the protein enzymes were measured using the Bradford method. The extracellular extract was concentrated using ammonium sulfate precipitation. PKL2 is gram-positive bacteria that was derived from eco-enzymes with the highest amylolytic indexes of 1.77, which were not pathogenic on the blood agar test. Optimum amylase was produced by PKL2 at the stationary phase at 21 h. The optimum pH and temperature of the amylase activity were observed to be 7.0 and 50°C, respectively. The amylase enzyme from PKL2 increased its purity 1.82-fold upon precipitation of ammonium sulfate at a concentration of 60%. Identification of bacteria based on molecular identification showed that PKL2 obtained was putatively identified as Bacillus amyloliquefaciens. Keywords: Amylase activity, Bacillus amyloliquefaciens, eco-enzyme, optimum pH

Abstract

Bagasse is one of the by-products of granulated sugar industries or processed beverages that become waste in the environment. The bagasse will be overgrown by cellulolytic bacteria that produce cellulase enzymes. This study aims to isolate, characterize, and measure bacterial cellulase activity qualitatively and quantitatively. The research phase included isolation and characterization of bacteria, qualitative cellulase activity test, preparing standard curves and bacterial growth curves, crude extract cellulase production, constructing standard glucose curves, quantitative enzyme activity tests, and data analysis. Six isolates with macroscopic characteristics varied in color, elevation, margins, and colony shape; three bacillus isolates, one short bacillus isolate, and two cocci isolates were obtained. All isolates showed positive test results of amylum, triple sugar iron agar, and catalase; five citrate-positive isolates, and three motile-positive isolates. From the cellulase qualitative test, two bacterial isolates had the highest cellulolytic index, namely AT1 (1.79) and BAW3 (1.72) on 0.5% CMC media. The quantitative cellulase test results of the two selected isolates were 0.01176 U/mL for AT1 and 0.01170 U/mL for BAW3, both of which are still classified as low degradation capabilities. Keywords: cellulase activity, cellulolytic index, Sugarcane waste
