Abstract

The effect of pH (4-9), NaCl concentration (1-5%), temperature and heating time (80, 100 and 1210C for 10, 20 and 30 minute) on the antibacterial effectivity of ethyl acetate and ethanol kecombrang extract were analysed. Both ethyl acetate and ethanol extracts showed antibacterial activity at pH 4-8, but its activity gradually decreased at higher pH. At pH 9, only ethanol extract still showed antibacterial activity. Addition of 1-4% NaCl on ethyl acetate and ethanol extract still showed antibacterial activity. Heating the extracts at 80-100 0C for 10-30 minutes and 1210C for 10 minutes did not haves significantly affect on the antibacterial activity of both ethyl acetate and ethanol extracts. Application of ethyl acetate extract at the concentration of 1 and 3 MIC on minced meat were still effective to reduce the viable bacteria until 7 days and 5 MIC was still effective until 9 days. Key words : Kecombrang, pH, NaCl, temperature and heating time, antibacteria

Abstract

In this study, kecombrang flowers was extracted with non polar (hexane), semipolar (ethil acetate) and polar (ethanol) solvent. The result revealed that ethil acetat and ethanol extracts inhibited 7 bacteria, i.e : spore forming bacteria (Bacillus cereus), Gram positive bacteria (Staphylococcus aureus) and (Listeria monocytogenes), Gram negative bacteria (Salmonella typhimurium, Aeromonas hydrophila and Escherichia coli), spoilage bacteria (Pseudomonas aeruginosa) but did not inhibit Lactobacillus plantarum. The hexane extract did not show antimicrobial activity. On well diffusion test, ethil acetate developed clear zones of 12.3 – 27.3 mm (diameters) and this was higher than ethanol extract 11.0-15.4 mm (diameters). The MIC (minimum inhibitory concentration) of ethil acetate and ethanol extract against the seven bacteria were 3-13 mg/ml. Key words : Kecombrang (Nicolia speciosa), antibacteria, extract

Abstract

Gula kelapa is a traditional and potencial comodity in Banyumas. Fortification with iodium in gula kelapa should be criteria were iodium in product over than 30 ppm bk. Fortification process was need a long thermal process. Stability of iodium in gula kelapa has been studied. The experimental method used Randomized Block Design. The factors analyzed were three kinds of fortification (fresh nira, nira prosessed, nira cristalization) and four kinds of iodium (control, NaI, KI, and KIO3) with 3 replications, and total were 36 unit. The result of the research showed that fortification when nira after endpoint with kalium iodida is the best interaction, iodium content is 34,89 ppm db. Key words : Brown sugar, fortification, iodine.

Abstract

Coconut sap is easily fermented during storage, so it is necessary to add preservative. Farmers usually use a solution of lime with mangosteen rind to preserve the sap. The availability of these preservatives are limited, so many farmers used synthetic preservatives like sodium metabisulfite. Some natural preservatives that can be used as an alternative to extend the shelf life of coconut sap were betel leaves, clove leaves, guava leaves, secang wood, and tea leaves. These materials have bioactive components that possess antimicrobial activity.This research was aimed to 1) determine the effect of types and concentration of natural preservatives to preserve freshness of coconut sap and brown sugar qualities, 2) determine the effect of the storage time on the quality of coconut sap. The research consisted of two stages and used experimental method with Randomized Block Design. The treatment of first stage included the type of natural preservative (M), consentration of preservative (K), and storage duration (L), while the second stage consisted of the best three natural preservatives from first stage (S) and concentration of preservatives (R). The results of this research showed that the coconut sap that was added with clove leaves (M4) with concentration of 4.5% (K1) gave highest pH value, levels of sucrose, sensory value, and inhibition of both the storage of 4 and 8 hours, followed by guava leaves (M5) and mangosteen rind (M1). Brown sugar is added three types of preservatives showed that no difference on water content, ash content, reduction sugar and total sugar content. These parameters meet SNI standard, except ash content only mangosteen rind and clove leaf that meets SNI standard. PERUBAHAN KUALITAS NIRA KELAPA AKIBAT PENAMBAHAN PENGAWET ALAMINira kelapa mudah terfermentasi selama penyimpanan, oleh karena itu diperlukan proses pengawetan. Petani biasanya menggunakan larutan kapur dengan kulit manggis untuk mengawetkan nira. Ketersediaan dari pengawet tersebut terbatas, sehingga banyak petani yang menggunakan bahan pengawet sintetis seperti natrium metabisulfit. Beberapa pengawet alami yang dapat dijadikan sebagai alternatif untuk memperpanjang umur simpan nira antara lain daun sirih, daun cengkeh, daun jambu biji, kayu secang, dan daun teh. Bahan-bahan tersebut memiliki komponen bioaktif yang mempunyai aktivitas antimikroba. Penelitian ini bertujuan untuk 1) mengetahui pengaruh jenis dan konsentrasi bahan pengawet alami dalam mempertahankan kesegaran nira dan kualitas gula merah, 2) mengetahui pengaruh lama penyimpanan terhadap kualitas nira kelapa. Penelitian ini terdiri dari dua tahap dan dilakukan dengan menggunakan metode eksperimen Rancangan Acak Kelompok (RAK). Perlakuan pada tahap pertama meliputi jenis pengawet alami (M), konsentrasi pengawet (K) dan lama simpan (L), sedangkan pada tahap kedua meliputi tiga jenis pengawet alami terbaik dari tahap pertama (S) dan konsentrasi pengawet (R). Hasil penelitian ini menunjukkan bahwa nira yang ditambah pengawet daun cengkeh (M4) dengan konsentrasi 4,5% (K1) memberikan nilai pH, kadar sukrosa, nilai sensori dan mempunyai daya hambat tertinggi baik pada penyimpanan 4 dan 8 jam, diikuti oleh pengawet daun jambu biji (M5) dan kulit manggis (M1). Gula merah yang ditambahkan dengan ketiga jenis pengawet terbaik tidak menunjukkan perbedaan terhadap kadar air, kadar abu, kadar gula reduksi dan kadar gula total. Ketiga parameter memenuhi standar SNI, kecuali kadar abu hanya pengawet kulit manggis dan daun cengkeh yang memenuhi standar SNI.

Abstract

One way to develop Micro, Small and Medium Enterprises (MSMEs) through higher education is by carrying out community service. Yoghurt Sehati MSMEs face obstacles in increasing the competitiveness of their products in an increasingly competitive market. Product packaging that is still simple is considered less able to attract consumer attention and needs to be improved in order to compete more effectively. This community service program aims to assist Yoghurt Sehati MSMEs in improving the design and information on their product packaging. The methods used in this service include socialization of activities, introduction of new labels and packaging, training and effective business development assistance. The community service team carried out activities that included improving packaging labels, introducing more informative packaging, and entrepreneurship training. Through this community service activity, the condition of MSMEs can improve, MSME knowledge increases, and marketing becomes more effective.

Abstract

PT. Banjarnegara Agro Mandiri Sejahtera (PT. BAMS) menghadapi tantangan dalam proses produksi dan pengemasan produk pangan olahan. Pengemasan manual menimbulkan rendahnya efisiensi, ketidakseragaman volume, dan risiko kebersihan yang tidak terstandar. Umur simpan produk yang hanya 18 bulan juga belum memenuhi permintaan pasar. Selain itu, variasi produk yang terbatas dan desain kemasan yang kurang menarik menurunkan daya saing. Solusi yang ditawarkan meliputi pemanfaatan ekstrak kecombrang sebagai pengawet alami untuk memperpanjang umur simpan hingga 24 bulan, serta pengadaan mesin filling otomatis guna meningkatkan efisiensi dan higienitas. Program juga mencakup pengembangan varian menu baru berbasis bahan lokal dan pembaruan desain kemasan yang lebih menarik. Pelaksanaan dilakukan bertahap melalui sosialisasi, pelatihan, penerapan teknologi, serta evaluasi. Targetnya adalah peningkatan kapasitas produksi dua kali lipat, kualitas produk yang lebih baik, dan daya saing yang meningkat di pasar nasional.
