Abstract

Breadfruit is one of the agricultural products with high starch content (> 20%), leading to the potential for starch source. The limitation of native breadfruit starch (NBS) in the application of Pickering emulsion was the main reason for preparing breadfruit starch nanoparticles in this research. Preparation of breadfruit starch nanoparticles with the nanoprecipitation method was a time-efficient method. Therefore, this research aimed to evaluate breadfruit starch nanoparticle preparation (BSN) in the nanoprecipitation method and its application in Pickering emulsion. Investigation of size and shape, FTIR profile, turbidity as well as visual appearance and creaming index of Pickering emulsion was conducted to support and confirm the objective of this research. This study found that micrometer scale, high hydroxyl groups, high turbidity of NBS were altered into the nanoscale, low hydroxyl groups, and low turbidity of BSN leading to the successful indication of preparation of breadfruit starch nanoparticle with nanoprecipitation method. The stability of Pickering emulsion improved with breadfruit starch nanoparticles, indicated by physical appearance and creaming index for 7-day storage at room temperature.

Abstract

Banyaknya buah mangga yang dijumpai di Indonesia menjadikan komoditas hasil pertanian ini layak untuk dipelajari potensinya dalam berwirausaha. Daging buah mangga mengandung berbagai zat gizi dan rasa yang manis sehingga dapat diolah menjadi banyak produk, seperti es krim. Pembuatan es krim mangga menjadi upaya yang tepat dalam menghasilkan produk potensial yang menguntungkan. Potensi ini sebaiknya dipahami oleh siswa SMK sebagai penerus generasi bangsa yang dapat menciptakan lapangan pekerjaan. Salah satu cara dalam memberi pemahaman kepada siswa SMK adalah berupa kegiatan sosialisasi tentang potensi wirausaha es krim mangga. Pada kegiatan ini tim pengabdian bermitra dengan SMKN 1 Kedawung Sragen yang memiliki visi dan misi serupa dengan tujuan kegiatan. Kegiatan ini merupakan pemicu semangat siswa untuk menghasilkan sesuatu yang bermanfaat dari segi ekonomi. Metode yang digunakan dalam kegiatan ini antara lain menyelenggarakan sosialisasi dan demonstrasi cara pembuatan es krim mangga serta menyampaikan potensi keuntungan dari berwirausaha es krim mangga. Dari pelaksanaan kegiatan pengabdian masyarakat, dapat dikatakan bahwa mayoritas para siswi SMKN 1 Kedawung Sragen mengalami peningkatan pemahaman terkait karakter buah mangga, olahan es krim mangga dan potensi wirausahanya, yang ditunjukkan dengan jawaban post-test yang diadakan oleh tim pengabdian masyarakat. Kata kunci: olahan buah mangga, es krim mangga, wirausaha ABSTRACT The large number of mangoes found in Indonesia makes this agricultural commodity worth studying for its potential for entrepreneurship. Mango fruit flesh contains various nutrients and tastes sweet so it can be processed into many products, such as ice cream. Making mango ice cream is the right way to produce profitable potential products. This potential should be understood by SMK students as the next generation of the nation who can create jobs. One way to provide understanding to vocational students is in the form of outreach activities about the entrepreneurial potential of mango ice cream. In this activity, the community service team partnered with SMKN 1 Kedawung Sragen, which has a vision and mission similar to the objectives of the activity. This activity is trigger the enthusiasm of students to produce something that is useful from an economic point of view. The methods used in this activity include organizing socialization and demonstrations on how to make mango ice cream and conveying the potential benefits of mango ice cream entrepreneurship. From the implementation of community service activities, it can be said that the majority of female students at SMKN 1 Kedawung Sragen experienced an increased understanding of processed mango ice cream and its entrepreneurial potential, as indicated by the answers to the post-test conducted by the community service team. Keywords: processed mango fruit, mango ice cream, entrepreneurship

Abstract

Rice is one of the staple foods of Indonesian people. Age keeps the rice short enough and the serving takes a long time to be a barrier for Indonesian people in consuming rice in all situations, especially emergencies. Making rice with special treatment, such as vacuum packaging and pasteurization is expected to overcome these problems. This rice product is called packaged rice. This study aimed to determine the level of vacuum and the suitable pasteurization method in the manufacture of packaged rice products. Vacuum packing followed by pasteurization (steaming and boiling) is the method of choice to produce packaged rice. The results showed that the vacuum level and pasteurization were not able to produce packaged rice that had a long shelf life, especially when stored at room temperature. This is indicated by the total results of microbes that exceed the safe limit, which is > 6 logs CFU/gram. The results of the total microbes affected the decrease of pH on days 4 and 7, and also the results of sensory evaluation on days 4 and 7, which was not suitable for testing to the panelists. However, cold storage has a better effect in terms of the shelf life of packaged rice products because the rate of microbial growth is inhibited so that the total microbial count is < 6 logs CFU/gram. Therefore, packaged rice products are recommended to be stored at cold temperatures before being consumed.

Abstract

Buah sukun mengandung pati yang tinggi sehingga dapat diolah menjadi pati sukun. Produk pati diketahui dapat berperan sebagai agen pengental dan pembentuk gel. Pada bidang pangan, sifat pengental dapat diterapkan pada pembuatan saus tomat dan sifat pembentuk gel dapat diterapkan pada pembuatan cendol. Tujuan penelitian ini untuk mengevaluasi penambahan pati sukun terhadap produk saus tomat dan cendol. Penelitian diawali dengan pengamatan sifat pasta dari pati sukun, seperti sifat pasta, uji warna, dan swelling power. Selanjutnya, pembuatan saus tomat dilakukan menggunakan prinsip pemasakan setelah pencampuran bubur tomat, bumbu, pati sukun, gula, dan garam. Sementara itu, pembuatan cendol dilakukan menggunakan prinsip pemasakan dan pendinginan di atas air es setelah pencampuran tepung beras, pati sukun, pewarna pandan, dan garam. Saus tomat dan cendol berbasis pati sukun diamati melalui kenampakan fisik produk. Hasil penelitian menunjukkan bahwa pati sukun memiliki nilai L sebesar 95,16 (warna putih cerah) dan swelling power sebesar 14,99 g/g. Sementara itu, viskositas puncak dan viskositas setback dari pati sukun berturut-turut sebesar 4795 cP dan 1731 cP, yang tergolong tinggi sehingga berpotensi untuk dijadikan pengental dan pembentuk gel pada produk pangan. Pada penerapannya, pati sukun dengan konsentrasi 1,3, dan 5% mampu mengentalkan saus tomat. Selain itu, pati sukun yang dicampur dengan tepung beras mampu membentuk gel yang kokoh pada cendol. Penelitian ini menjadi informasi yang bermanfaat dalam pengaplikasian pati sukun pada produk pangan, seperti saus tomat dan cendol, serta menjadi area riset yang menjanjikan untuk dieksplorasi.
