Abstract

Abstract. The functions soil depends on the balances of its structure, nutrients composition as well as other chemical and physical properties. Conventional methods, used to determine nutrients content on agricultural soil were time consuming, complicated sample processing and destructive in nature. Near infrared reflectance spectroscopy (NIRS) has become one of the most promising and used non-destructive methods of analysis in many field areas including in soil science. The main aim of this present study is to apply NIRS in predicting nutrients content of soils in form of total nitrogen (N). Transmittance spectra data were obtained from a total of 18 soil samples from 8 different sites followed by N measurement using standard laboratory method. Principal component regression (PCR) with full cross validation were used to develop and validate N prediction models. The results showed that N content can be predicted very well even with raw spectra data with coefficient correlation (r) and residual predictive deviation index (RPD) were 0.95 and 3.35 respectively. Furthermore, spectra correction clearly enhances and improve prediction accuracy with r = 0.96 and RPD = 3.51. It may conclude that NIRS can be used as fast and simultaneous method in determining nutrient content of agricultural soils.

Abstract

An environmentally friendly packaging material that can be used in place of synthetic, non-green plastic packaging is biodegradable film. Therefore, this study aims to determine the effect of sorbitol plasticizer concentrations on the characteristics of biodegradable film produced from chicken claw waste. The treatments applied during the production process consisted of three sorbitol concentrations, including 0.5, 1, and 1.5%, repeated thrice. Characterization of biodegradable film comprised thickness, water content, water solubility, film swelling, mechanical properties, pH, water vapor permeability, oxygen permeability, and degradation tests. Analysis of variance  results showed that the sorbitol concentrations significantly influenced thickness value, but did not affect other characteristics. The best treatment was 0.5% sorbitol which generated thickness of 0.15 mm, WC of 13.97%, WS of 44.72%, swelling of 96.97%, tensile strength of 12.29 MPa, elongation of 22.23%, elasticity 58.53 Mpa, pH 7.5, WVP 9.26 g.m -1 pa -1 hour -1 , OP 1.52 g.m -1 pa -1 , and degradability for 14 days.

Abstract

The main purpose of this present study is to evaluate the ability of near infrared technology as an alternative method in determining and assessing quality parameters of meat product where in this case is frozen beef. At first, beef samples from chest and legs parts were sliced and taken at the amount of 100g per sample to be frozen. Then spectra data of beef samples were obtained using near infrared spectrophotometer (PSD IR i16) in wavelength range from 1000 to 2500 nm with optical gain 4x. Actual protein contents were obtained by Kjeldahl method and measured in triplicate. The near infrared spectra data were enhanced and improved by means of mean centering (MC) and baseline shift correction (BSC) methods. The results showed that protein content of frozen beef samples can be predicted rapidly with maximum correlation coefficient is 0.91. Heat properties of beef samples changes exponentially during freezing and thus, optimum freezing temperature and time can be predicted as well. Based on those obtained results, it may conclude that near infrared technology can assess frozen beef qualities rapidly and effectively.

Abstract

Farmers in Lieue Village, Darussalam District, Aceh Besar still use the handweeding method to control weeds in vegetable crops. This method takes a long time, making the weed control process less effective. In addition, the small amount of labor is not proportional to the area of vegetable crops, so the weed control method is less efficient. To overcome this, the partner community is offered a solution to the mechanical weed control method, namely by using a cultivator power weeder. The weed control tool offered is an engine-driven tool mounted on an iron frame with two iron wheels equipped with blades that function as soil cultivators and weed cutters. When the machine is turned on and running, the soil will be processed while cutting weeds and controlling weeds. The cultivatorpower weeder offered is an innovation developed by the Weed Management Laboratory of the Agrotechnology Study Program and the Agricultural Equipment and Machinery Laboratory of the Faculty of Agriculture, Syiah Kuala University. It is hoped that with this weed control tool, the weed control process in vegetable crops can be more effective and efficient and ultimately can increase the yield of vegetable crops of farmers in Aceh Besar.The results of the service showed that the service team had succeeded in making a power weeder cultivator as a mechanical weed controller using a driving machine. However, the tool that has been made turns out to be rather difficult to move. Therefore, wheels were added to the front to make it easier to move. This tool can be used for weed control in horticultural and food crops. To date, farmers have tried and used the power weeder cultivator as a mechanical weed controller to control weeds in vegetable crops in various target villages.

Abstract

Abstrak. Jeruk nipis kering berpotensi digunakan sebagai bahan alternatif dalam pembuatan infused water yang lebih aman dibandingkan jeruk nipis segar karena masa simpannya lebih panjang dan risiko pertumbuhan mikroorganismenya lebih rendah. Pengeringan turut berperan mempertahankan kualitas serta nilai gizi, sehingga produk tetap bermanfaat saat dikonsumsi. Penelitian ini bertujuan mengevaluasi pengaruh variasi suhu pengeringan terhadap mutu irisan jeruk nipis sekaligus menganalisis aspek biaya prosesnya. Rancangan penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan lima taraf suhu, yaitu 40C, 50C, 60C, 70C, dan 80C. Parameter mutu yang diamati meliputi kadar air, laju pengeringan, dan kadar vitamin C. Analisis ekonomi mencakup biaya tetap, biaya variabel, biaya total, biaya pokok pengeringan, dan rasio B/C. Hasil penelitian menunjukkan bahwa suhu pengeringan tidak berpengaruh nyata terhadap kadar air akhir, tetapi berpengaruh signifikan terhadap kadar vitamin C. Suhu 80C menghasilkan laju pengeringan tertinggi dengan waktu tercepat (420 menit), namun menurunkan kadar vitamin C lebih besar. Sebaliknya, pengeringan pada 40C mampu mempertahankan kadar vitamin C lebih tinggi, meskipun membutuhkan waktu lebih lama (25 jam). Analisis ekonomi menunjukkan nilai rasio B/C1, yang mengindikasikan bahwa proses pengeringan jeruk nipis kering layak secara finansial dan berpotensi untuk dikembangkan pada skala agroindustri kecil hingga menengah.The Effect of Temperature Variation on the Quality and Cost of Drying Lime Slices (Citrus aurantifolia Swingle)Abstract. Dried lime has the potential to be used as an alternative ingredient in the preparation of infused water, offering greater safety compared to fresh lime due to its longer shelf life and lower risk of microbial growth. The drying process also plays an important role in maintaining the quality and nutritional value of lime, ensuring that it remains beneficial for consumption. This study aimed to evaluate the effect of different drying temperatures on the quality of lime slices as well as to analyze the economic aspects of the drying process. The experiment was arranged using a Completely Randomized Design (CRD) with five levels of drying temperature: 40C, 50C, 60C, 70C, and 80C. The quality parameters observed included moisture content, drying rate, and vitamin C content. The economic analysis covered fixed costs, variable costs, total costs, unit cost of drying, and the B/C ratio. The results showed that drying temperature had no significant effect on the final moisture content but significantly affected the vitamin C content. Drying at 80C produced the highest drying rate with the shortest processing time (420 minutes) but resulted in a greater reduction of vitamin C. Conversely, drying at 40C retained higher vitamin C content, although it required a longer drying time (25 hours). The economic analysis indicated a B/C ratio greater than 1, demonstrating that the lime drying process is financially feasible and has the potential to be developed on a small- to medium-scale agroindustry.
