Abstract

The extremely low frequency (ELF) magnetic field exposure technology for food processing and preservation is a future technology that produces better food quality. This research aims to examine the exposure of extremely low frequency (ELF) magnetic field waves to pasteurized cow milk and its effect on pH, chemical content, total microbial count, and sensory tests. This research was carried out by exposing ELF waves of 834.8 micro Tesla (μT) for 90 minutes to fresh milk and pasteurized milk. Samples were stored at room temperature then observed at 0, 2, 6, and 21 hours. Each treatment was repeated three times. The results showed that exposure to ELF waves had no effect on chemical content (P<0.05). The pH measurement shows that exposure to ELF waves could maintain the pH value. The total microbial count showed that exposure to ELF waves had an effect on reducing the total microbial count. The organoleptic test showed that pasteurized milk exposed to ELF waves had a smaller level of change. Based on observations, exposure to ELF waves has the potential to be developed in pasteurization, storage of cow milk, and retain its nutritional content. Keywords: Cow milk, Exposure, Extremely low frequency, Influence, Pasteurization.

Abstract

Mango (Mangifera indica L) is one of commodities with high food loss rate due to the characteristics of mango, which is easily spoiled and difficult to store. One of the strategies to reduce mango food loss caused by post-harvest handling is the diversification of mango products. Mango flour can be developed to minimize mango food waste and enhance its added value. This study aimed to determine the optimum formulation for making mango flour. The study used Response Surface Methodology (RSM) type Central Composite Design (CCD) to optimize mango flour yield, using three factors: rice flour concentration (X1: 2 5%), maltodextrin concentration (X2: 2-5%), and tapioca flour concentration (X3: 2-5%). The significance of response was carried out using analysis of variance (ANOVA) at the 95% confidence level (p<0.05). The linear model was the model suggested by software. Model analysis showed that rice flour and tapioca flour concentration significantly affected mango flour yield, while maltodextrin did not have a considerable impact. Based on the results of this study, the optimum conditions in making mango flour were found using rice flour concentration of 4.94%, maltodextrin concentration of 2.25%, and tapioca flour concentration of 4.88% to produce mango flour yield of 20.9578%. Keywords: Mango flour, Optimization, Response surface methodology, Yield.

Abstract

Koro pedang (Canavalia ensiformis) merupakan potensi sumber protein nabati lokal yang belum dimanfaatkan secara optimal. Kacang koro pedang merupakan alternatif penggunaan kedelai impor dalam pembuatan tempe. Program pengabdian masyarakat ini bertujuan untuk mengimplementasikan Metode Polije dalam mengoptimalkan produksi tempe koro pedang pada Kelompok Usaha Bersama (KUB) Pengrajin Tempe Pondok Pesantren Al Ishlah Jenggawah, Jember. Metode yang digunakan meliputi sosialisasi, pelatihan, dan pendampingan teknis melalui tiga tahap utama: praktik metode baru, pelatihan preparasi limbah whey tahu sebagai media perendaman, dan pelatihan perbanyakan bakteri L. plantarum Polije 15420. Hasil kegiatan menunjukkan bahwa penggunaan whey tahu mampu mempersingkat waktu perendaman dari 12–24 jam menjadi hanya 6–8 jam. Selain itu, implementasi Metode Polije berhasil meningkatkan masa simpan tempe dari 2 hari menjadi 7 hari. Penggunaan alat pencuci bahan baku mekanis juga terbukti meningkatkan efisiensi waktu sebesar 15–30 menit per 100 kg bahan baku dan mengurangi risiko kehilangan bahan baku hingga 5% dibandingkan metode tradisional. Program ini telah memberdayakan mitra melalui peningkatan keterampilan teknis dan efisiensi produksi.

Abstract

Pengering Dehumidifier merupakan pengering buatan untuk mengeringkan bahan yang sensitif terhadap panas. Pengering dehumidifier telah dibuat dan dilengkapi dengan inverter untuk mengatur kecepatan blower, thermostat untuk mengontrol temperatur di evaporator serta elemen pemanas dilengkapi thermoregulator untuk mengontrol temperatur udara pengering. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh debit udara dan temperatur pemanasan terhadap nilai RH dan ketepatan pengontrolan temperatur udara pengering. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap dengan 2 faktorial yaitu debit udara dan temperatur pemanasan. Debit udara terdiri dari 0,014 dan 0,029 m3/s dan temperatur pemanasan terdiri dari 35 oC dan 40 oC. Masing-masing perlakuan diulang sebanyak 3 kali. Analisis data menggunakan analisis ragam ANOVA dilanjutkan uji BNT 5%. Ketepatan pengontrolan temperatur udara pengering dianalisis menggunakan galat relatif. Berdasarkan hasil penelitian disimpulkan bahwa nilai RH udara pengering berbanding lurus dengan debit udara dan berbanding terbalik dengan temperatur pemanasan udara. Semakin tinggi debit udara semakin tinggi nilai RH udara pengering dan semakin tinggi temperatur pemanasan semakin rendah nilai RH udara pengering. Perlakuan terbaik pada debit udara 0,014 m3/s dengan temperatur pemanasan 40 oC yaitu dihasilkan nilai RH 35,47%. Pengontrolan temperatur pemanasan sangat baik dengan nilai galat relatif 1,3% dibawah 5%.

Abstract

Indonesian has been ranked as 5th mango producer in the world with total production reached 2.18 million, however, Indonesian has not included the top ten world mango exporter countries. Indonesian total export was 1,240 tons and only fulfilled 0,6% of the world export value. PT. Trigatra Rajasa is one of the Arumanis 143 mango producers in Indonesian. The research objective was to analyze internal and external factors which influence marketing mango of PT Trigatra Rajasa including the arrangement of strategic recommendation to incline market value. Data collection was done from January to May 2019 through observation and respondent interview. Questioner with SWOT (Strengths, Weaknesses, Opportunities, Threats)and QSPM (Quantitative Strategic Planning Matrix) method was used during the interview. Analysis tools such as IFE, SWOT and QSPM were utilized in this research. The result showed that IFE (internal factor evaluation matrix) and EFE (external factor evaluation matrix) calculation matrix were given total score 2,85 and 2,8, respectively. Adding result of both matrix was positioning the mango marketing reality of PT Trigatra Rajasa in compartment V, mean hold and maintain. In this compartment, market penetration and product development strategy were suggested to be applied. Market penetration was recommended strategy to increase marketing of mango PT. Trigatra Rajasa based on QSPM (4,03) and efficiency of production budget through the utilization of mechanization (3,00) were suggested.
