Abstract

Maesan is one of the sub-districts in Bondowoso Regency, where people primarily work in agriculture. In Maesan sub-district, there is a KWT (Farmer Women's Group) Karya Bunda, which does not have superior products processed tomatoes or spinach. Maesan people use tomatoes and spinach as daily vegetables. The availability of tomatoes and spinach in Maesan is relatively abundant. If the harvest is large, the price of tomatoes is meager, so they are not harvested by farmers and suffer heavy losses. One of the diversions of processed food is tomato sauce and spinach chips. KWT Karya Bunda has never used tomatoes and spinach as diversified products. So it is necessary to socialize and train how to produce tomato sauce and spinach chips. Moreover, test the favorability of tomato sauce and spinach chips. We hope it can be developed and impact KWT Karya Bunda's income. 34 participants of KWT Karya Bunda attended the socialization activity. The socialization activity consisted of presenting post-harvest technology material and how to make tomato sauce and spinach chips, making tomato sauce and spinach chips and filling out a sensory questionnaire (liking) for spinach sauce and chips with a google form. The participants of KWT Karya Bunda were very enthusiastic about making tomato sauce and spinach chips. The results of sensory data showed that 79.4% very liked tomato sauce, and 20.6% liked tomato sauce. Meanwhile, the sensory assessment of spinach chips was 64.7% very like and 35.3% like. This shows that both products have the potential to be developed as KWT's main products. Keywords: maesan, KWR Karya Bunda, tomato sauce, spinach chips

Abstract

          Plastik merupakan kemasan pangan yang umum digunakan namun memiliki sifat sukar dihancurkan sehingga menyebabkan pencemaran lingkungan dan masalah kesehatan. Plastik biodegradable berbasis renewable material seperti singkong, whey keju, dan gliserol dapat menjadi alternatif kemasan yang ramah lingkungan. Whey keju mengandung protein sebesar 0,6 % yang berpotensi menjadi bahan bioplastik dengan penambahan bahan lain seperti hidrokoloid (protein dan polisakarida) untuk memperbaiki karakteristiknya. Plastik biodegradable berbahan baku polisakarida tanaman seperti ubi kayu umumnya bersifat kaku dan rapuh sehingga harus ditambahkan bahan lain. Pembuatan plastik biodegradable memerlukan bahan pemlastis seperti gliserol untuk meningkatkan elastisitas polimer plastik dan mengurangi kerapuhan bioplastik. Tujuan penelitian ini yaitu mengetahui pengaruh perbedaan variasi volume whey keju dan gliserol terhadap karakteristik fisik, mekanik, dan biodegradasi plastik biodegradable. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 3 ulangan dan terdapat 2 faktor perlakuan. Faktor pertama yaitu variasi volume whey keju dan faktor kedua yaitu variasi volume gliserol. Berdasarkan hasil penelitian dapat disimpulkan bahwa variasi volume whey keju dan gliserol berpengaruh nyata terhadap kuat tarik, elongasi, elastisitas, daya serap air, dan daya degradasi. Hasil uji efektivitas menunjukkan bahwa formulasi terbaik terdapat pada sampel A1B1 yaitu plastik biodegradable dengan formulasi whey keju 20 ml dan gliserol sebesar 5 ml dengan nilai perbedaan warna (∆E) 15,526 dengan L* (lightness) 85,68, a* (redness) 0,2, b* (yellowness) 8,71, daya serap air sebesar 695,244 %, kuat tarik sebesar 0,00646 MPa, elongasi sebesar 76,36 %, elastisitas sebesar 0,01033 MPa, dan laju degradasi sebesar 12,035 %/hari.

Abstract

Family medicinal plants (TOGA) are efficacious as medicines to fulfil the needs of family medicines. TOGA has many types of plants that can be used for roots, leaves, bark, flowers, and rhizomes depending on the type of plant. One of the TOGA that is used for its rhizomes is ginger. Ginger contains phenolic compounds such as gingerols, shogaols, zingeron, and diarylheptanoids which have antioxidant activity. Ginger is generally used as a ginger drink. Making ginger tea is also considered impractical because you have to peel the ginger first. So it is necessary to carry out technical guidance on processing ginger into instant ginger granules. Processing into granules was chosen because it is more stable physically and chemically and does not easily agglomerate. The purpose of this community service is to transfer knowledge and technology in the cultivation and processing of instant ginger. This community service was carried out for 25 housewives of RT 5 RW 2 in Mojoroto Village, Mojoroto District, Kediri City. This activity was divided into two stages, namely the stage of giving lectures and field practice, namely ginger cultivation and ginger processing. The results of the community service showed that during the lecture stage, the cultivation of ginger in used sacks, and the processing of instant ginger granules received very positive responses from the participants. Many participants followed closely and communicated actively with the community service team.  Tanaman obat keluarga (TOGA) berkhasiat untuk obat dalam mencukupi kebutuhan obat-obatan keluarga. Beberapa jenis TOGA dapat dimanfaatkan akar, daun, kulit batang, bunga, dan rimpangnya. Salah satu TOGA yang dimanfaatkan rimpangnya adalah jahe. Jahe mengandung senyawa fenolik seperti gingerol, shogaol, zingeron, diarilheptanoid yang memiliki aktivitas sebagai antioksidan. Jahe umumnya digunakan sebagai wedang jahe. Pembuatan wedang jahe pun dirasa kurang praktis karena harus mengupas jahe terlebih dahulu. Maka perlu dilakukan bimbingan teknis pengolahan jahe menjadi granul jahe instan. Pengolahan menjadi granul dipilih karena lebih stabil secara fisik dan kimia serta tidak mudah menggumpal. Tujuan pengabdian kepada masyarakat ini untuk berbagi ilmu dan teknologi dalam budidaya dan pengolahan jahe instan. Sasaran kegiatan ini adalah ibu-ibu rumah tangga RT 5 RW 2 sebanyak 25 orang di Kelurahan Mojoroto Kecamatan Mojoroto Kota Kediri. Kegiatan ini dilakukan dengan dua Langkah, yaitu memberikan ceramah dan praktek lapang yaitu budidaya jahe serta pengolahan jahe. Hasil pengabdian kepada masyarakat menunjukkan bahwa pada tahap ceramah, budidaya jahe dalam karung bekas dan pengolahan granul jahe instan sangat mendapatkan respon positif dari peserta. Banyak peserta yang mengikuti dengan seksama dan berkomunikasi secara aktif kepada tim pengabdian kepada masyarakat.

Abstract

Sardinella lemuru is one type of fish with the highest population and the most widely caught fish in Indonesia. The protein content is very high, namely 17.8-20% contains various amino acids including glutamic acid, which can potentially be a smart flavor precursor. The research focuses on enzymatic smart flavor production by examining the effect of concentration and hydrolysis time of calotropin and papain combination on characteristics of the smart flavor produced and determining the best treatment to produce smart flavor. This research used two factors: the concentration of enzyme (3%, 4%, and 6% with a ratio of papain and calotropin of 70%: 30%) and hydrolysis time (1, 2, and 3 hours). The research showed that yield ranged from 50.15-50.69%; brightness 89.72-91.57; water 6.91-9.51%; soluble protein 1.13-1.56 mg/ml; antioxidant activity 48.40-54.47%; emulsion power 0.16-0.18 m2/g, emulsion stability 17.27-24.33 minutes; water holding capacity 83.44-89.27% and effectiveness 1.00 (enzyme 6% and time of hydrolysis 3 hours). The best treatment with effectiveness was Sardinella lemuru smart flavor (6% enzyme and 3 hours hydrolysis) with a yield 50.54%, brightness 89.72, water 6.91%, soluble protein 1.56 mg/ml, antioxidant activity 54.47%, emulsion power and stability 0.18 m2/g and 24.33 minutes, and water holding capacity 89.27%.

Abstract

Antioxidant compounds in food are generally less stable when applied to food, so technology is needed to help antioxidant compounds become more stable during storage, one of which is microencapsulation. The research aims to determine the effect of the wall material ratio and drying methods on the characteristics of Sardinella lemuru smart flavor microcapsules. The experimental design used was a two-factor Complete Random Design (CRD): ratio of wall materials (maltodextrin: Arabic gum) and drying methods (spray drying and freeze drying). The research showed that enzyme activity ranged from 14.81-52.64 U/mL; lightness 95.2-100; yield 4.00-17.19%; water content 2.26-9.15%; antioxidant activity 15.75-31.23%; encapsulation efficiency 69.06-78.47%. Microcapsules with the highest water content, lightness, antioxidant activity, and encapsulation efficiency were at the ratio wall materials (maltodextrin: Arabic gum) of 7:3 by spray drying, 9.15%, 100, 31.23%, and 78.47%. On the other hand, the highest yield (17.19%) was at the ratio wall materials (maltodextrin: Arabic gum) 8:2 by freeze-drying. The morphology of the microcapsules by spray drying is spherical, and freeze drying makes it flaky and sharp.

Abstract

The Cempakaan Dukuh farmer group in Dukuh Mencek Village, Sukorambi District, Jember Regency, actively cultivates various vegetables. Currently, this farmer group lacks knowledge and skills in processing technology for vegetable-based food products. As a result, their vegetable harvests are mainly sold in fresh form, either directly to consumers or through intermediaries, which keeps their selling prices low. To address this issue, a training program was implemented to enhance the farmers' understanding and skills in processing technology, specifically focusing on creating water spinach jerky and spinach sticks. The training involved several steps: organizing coordination meetings to prepare for the activities, delivering the training materials, facilitating discussions, and providing hands-on practice. Finally, the outcomes of the service were evaluated and reviewed. The results of the training showed that the farmer group was enthusiastic about participating in the community service activities. To evaluate their progress, pre-test and post-test assessments were conducted. The pre-test scores for each question were 56, 32, 54, 48, 40, and 45, while the post-test scores were 87, 83, 86, 80, 75, and 73. The increase in post-test scores indicates a significant improvement in the farmers' ability to utilize technology for processing water spinach jerky and spinach sticks.
