Abstract

Slope length and steepness factor index (LS) is one of the parameters for the Universal Soil Loss Equation (USLE) to estimate soil erosion. Currently, several methods for LS analysis, i.e. Wischmeier-Smith, Moore-Nieber, and Desmet – Govers. This study aims to compare the Wischmeier-Smith method, Moore–Nieber method, and Desmet–Govers method to analyze LS in the watershed in Manokwari – West Papua. This research consists of 4 main stages, i.e. data inventory, watershed boundary delineation, LS analysis, and LS comparison. The research showed that the Wischmeier-Smith method gave a higher LS value than the Moore – Nieber method and the Desmet – Govers method. Meanwhile, the Desmet – Gover method gives a lower average LS value than the Wischmeier-Smith method and the Moore – Nieber method. Based on the T-test, the LS produced by the Wischmeier-Smith, Moore-Nieber, and Desmet–Govers methods has significant differences in analyzing LS in the watershed in Manokwari – West Papua. Keywords: Desmet – Govers, Moore – Nieber, Universal Soil Loss Equation, Watershed, Wischmeier-Smith

Abstract

The purpose of this study is to determine the suitability and productivity level of Bambara beans in the Special Region of Yogyakarta, especially to determine and examine the effect of the use of organic fertilizer from livestock manure on the growth and yield of Bambara beans. The implementation of the study involved a multi-location test of Bambara bean cultivation in three subdistricts, namely Tempel, Sedayu, and Cangkringan. In these three areas, manure was applied with 3 dose variations, namely 10 tons/Ha, 20 tons/ha and 30 tons/ha. The study was arranged in a Completely Randomized Design (CRD) where each treatment was carried out with 3 replication plots. The test results showed that the dose of manure was not significantly different from the production of Bambara beans. Therefore, a dose of manure of 10 tons/ha can be recommended to achieve higher economic benefits in Bambara bean cultivation. In addition, based on the evaluation of the growth phase and plant yield, the location of Bambara bean planting in Tempel gave higher yields compared to Sedayu and Cangkringan. Bambara bean cultivation in Tempel can produce 686.45 g/plot. Keywords: Bambara beans, Growth, Multilocation test, Organic fertilizer, Yield.

Abstract

Thermoplastic starch (TPS) is a biofilm made from starch and cellulose. The advantage of thermoplastic starch is easily degraded. TPS has weaknesses in high water affinity and low mechanical properties, so it is necessary to add polyvinyl alcohol (PVA) in making TPS packaging. The mechanical properties of TPS-PVA can be further improved by modifying it into a composite with coconut fiber cellulose. This research was purposed to produces a film containing cellulose from coconut fiber as a reinforcing material for film composites as well as to evaluate the biodegradation properties of the resulting film. It is known that the addition of 5% w/v coconut cellulose fiber is the formulation with the best yield when compared with the 1% and 3% w/v formulations. Applying TPS film to chilies can increase the shelf life of chilies. As a product that spoils quickly, one of the efforts made to maintain the quality of chilies is to use packaging made from TPS. Storing chilies at different temperature conditions using TPS-PVA film packaging with the addition of 5% w/v coconut fiber cellulose was able to maintain the shelf life and quality of chilies for 19 days at cold temperatures. Keywords: Chilies, Cellulose, Thermoplastic starch

Abstract

The landscape changes through the increasing built-up areas (settlements and industrial) have a potential impact on reducing the quality of agricultural land. Waste from anthropogenic activities (industrial and domestic) is the main source of heavy metals that can affect rice production in the fields. This study examines the quality changes of paddy fields (Oryza sativa L.) polluted by wastewater in Muara Bakti Village, Bekasi Regency. Wastewater's impact on paddy fields is known through heavy metal contamination analysis in soil and rice plants. Chemical analysis of soil, water and plants was completed by the Balai Penelitian Tanaman Sayuran (Balitsa) Laboratory, West Bandung. The results showed that heavy metal levels such as lead (Pb) and cadmium (Cd) in the paddy soil samples were above the threshold in soil, respectively more than 25 mg/l and 0.01 mg/l. In contrast, the rice plant samples, it was identified as containing heavy metals such as Cd and chromium (Cr). Pb content was not detected in the rice plants. Soil in Muara Bakti Village contained optimal nutrients that are still suitable for agriculture. However, heavy metal content detected in soil samples and rice plants requires special handling to prevent endangering the agroecosystem and human health. Keywords: Agroecosystem, Heavy metals, Paddy fields, Soil pollution, Waste

Abstract

PT. XYZ is a company that operating in the canned fish processing sector. In implementing the traceability system, traceback product still experiences obstacles so it cannot be implemented properly in the Company. This research was conducted to determine the traceability critical point which is a weakness of the traceability system being implemented. The method used is the FMECA (Failure Modes, Effects, and Criticality Analysis) approach, which is a development of the FMEA (Failure Mode Effect Analysis) method with the inclusion of the CA (Criticality Analysis) method to evaluate the effective level and efficiency of the traceability system being implemented. The results of the analysis showed that 43 possible failure points were identified, of which 2 points were in the unacceptable area, 3 points were in the undesirable area, 12 points were in the acceptable with revision area, and 26 points were in the acceptable without revision area. Traceability of canned fish products at fish canning companies has been going well with 5 critical points of traceability, namely the absence of information on the origin of the fish, not providing special coding for each fish received, not carrying out microbiological testing on the fish received, each fish received is not differentiated. The storage location is between each supplier, and no special records are made at the draining stage. Keywords: Critical analysis, Failure, FMECA, Traceability, Quality assurance.

Abstract

Soil tillage has both positive and negative impacts on soil quality and crop productivity. Efforts to reduce the negative impacts of intensive soil tillage are urgently needed. This study aims to analyze the impact of intensive soil tillage on soil fertility parameters (pH, available P, organic-C, soil compaction, aggregate stability, and soil biodiversity). This research was conducted in two land uses: agriculture and forest land. The research design was descriptive-explorative through surveys and direct field observations. The sample points were determined using stratified random sampling with 3 replications (24 samples). Parameters analyzed in this study were soil compaction, aggregate stability, soil pH, soil available-P, and soil biodiversity (total microbial, soil meso-and-macrofauna). The results showed that intensive tillage affected the soil microbial population, aggregate stability, pH, and available-P (p<0.05). The negative impact of intensive soil tillage reduced total soil microbes by 59.37%. The soil macro and mesofauna found at the study site were earthworms and mycorrhizae, which had a higher density on non-tillage land, with trees as the main vegetation. This encourages efforts to introduce conservation soil tillage to maintain soil biodiversity before more severe damage occurs. Keywords: Intensive agriculture, Soil degradation, Soil fertility, Soil quality, Soil structure.

Abstract

Rosella (Hibiscus sabdariffa L.) is known as a plant whose calyx contain high levels of antioxidant bioactive compounds and good inhibitory power against free radicals. However, other parts of the rosella plant have not yet been utilized for their antioxidant content and activity. The aim of this research is to compare the profiles of essential oils of parts of the rosella plant (seeds, leaves and flower petals) and their antioxidant activity. This research method begins with the process of extracting essential oils using the water-steam distillation method. Furthermore, the profile of the essential oil is known from the results of yield calculations and characterization using the GC-MS instrument. The antioxidant activity was tested using the DPPH method. The yield of essential oils obtained was 0.0107% for seeds, 0.0087% for leaves and 0.0136% for flower petals. GC-MS characterization shows that the most abundant chemical components contained in the essential oils of seeds, leaves, and flower petals are fatty acid compounds (2-propanoic acid, butanoic acid, hexanoic acid) and esters (neopentyl isobutyrate). The results of the antioxidant activity test showed the IC50 value for each essential oil, namely, seeds: 30.15 μg/ml, leaves: 171.27 μg/ml and flower petals: 126.58 μg/ml. The compound characteristics obtained showed the best results for rosella seed essential oil, this was supported by the fairly high antioxidant activity test results IC50 <50 μg/ml. Keywords: Antioxidant activity, Characterization, Essential oils, IC50, Yield.

Abstract

The objective of this study is to optimize the number of vanes equipped in the propeller of a mist blower's nozzle. Performance tests were conducted on the approved sprayer test bed, also known as a patternator, to measure several parameters, including effective spraying discharge, effective spraying width, spraying angle, effective spraying height, effective spraying range, droplet diameter, and droplet density. The vane number was optimized using the weighting method. The results indicate that increasing the number of vanes used is directly correlated with higher values of effective spraying width (ESW), spraying angle, effective spraying range (ESR), and droplet density. Conversely, it is inversely correlated with the value of effective spraying discharge (ESD), effective spraying height (ESH), and droplet diameter. The vane number was optimized using the weighting method. The most effective results in the mist blower performance test are achieved by using 12 vanes. This configuration produces droplets with a diameter of 195.44 ±9.68 μm and a density of 320 ± 17.44 droplets/cm2. The mist blower also has ESW of 136 ± 1.73 cm, ESH of 68.14 ± 4.19 cm, ESD of 4.41 ± 0.14 L/min, and ESR of 5.76 ± 0.04 m. Keywords: Agricultural spraying, Mist blower, Nozzle optimization, Performance evaluation, Vane number.
