Abstract

Penelitian ini bermaksud untuk mengetahui pengaruh substitusi parsial tepung ubi  ungu terhadap karakteristik fisik pizza meliputi warna beserta tekstur. Variabel bebas terdiri dari konsetrasi tepung ubi ungu, sedangkan variabel terikat berupa sifat fisik, yaitu warna dan tekstur. Terdapat 6 variasi subtitusi tepung ubi ungu, yaitu pada penambahan 0, 10, 20, 30, 40 dan 50%. Data dianalisis sebanyak dua kali repetisi perlakuan serta dua kali repetisi analisis sifat fisik menggunakan One Way ANOVA untuk analisis statistik. Apabila didapati selisih pada sampel, selanjutnya dianalisis DMRT pada taraf signifikansi 5%. Hasil penelitian menunjukkan bahwa pizza tepung ubi ungu memiliki tekstur cenderung empuk sampai substitusi 30%. Pada penambahan tepung ubi ungu konsentrasi 40% menghasilkan tekstur pizza yang semakin keras. Berdasarkan hasil uji warna, pizza dengan penambahan tepung ubi ungu 10% memiliki warna cenderung cerah, sementara pada substitusi konsentrasi 20% warna pizza cenderung semakin gelap.

Abstract

Mango is a fruit favorite of tropical people and oranges Lime is rich in vitamin C as well abundant available moment season harvest. As an easy commodity broken, needed innovation to get consumed moment no season harvest. Innovation possible processing one of them did fruit leather. Fruit leather is a product layer flt practica, durable and worth economical. Influence variation temperature drying (50 °C; 60 °C; 70 °C; and 80 °C) to characteristics physical that is color and texture as well as Vitamin C levels of fruit leather were observed with us the method Draft Random Complete (RAL) Non-Factorial. Therefore a sensory test was carried out on the resulting product on 25 panelists no trained . From the results research fruit leather mango with a temperature of 60 o C is sufficiently preferred with a content of vitamin C 1of 5.74 (mg/100 g) and water content of 11.59 (% db ) and texture 4365.58 g and color L = 53.81, a= 21.29, b = 48.58).

Abstract

 Purple sweet potato flour (Ipomea batatas L.) can be developed as a partial substitute in processing wheat flour-based food products such as pizza. Pizza has a thin round shape with the addition of various toppings on it. This study aims to determine the effect of adding purple sweet potato flour in pizza making on the organoleptic and chemical characteristics of the resulting pizza product. There were 6 variations of pizza with purple sweet potato flour substitution concentration of 0%, 10%, 20%, 30%, 40% and 50%. This study used a completely randomized design method with two repetitions. The resulting pizzas were tested sensory including preference tests as well as differentiation tests (sweet potato flavor, sweet potato aroma, dark purple color, and soft texture). Furthermore, the selected pizzas were analyzed chemically, including proximate analysis and antioxidant activity. Based on statistical tests showed that the addition of purple sweet potato flour was quite favorable at a concentration of 30% with a water content of 44.45%, ash content of 3.48 (% db), protein content 10.26 (%db), carbohydrate content 74.89 (%db) with energy 239.58 (cal/100 g) and antioxidant activity (RSA) 71.26%. Keywords: antioxidant activity, pizza, purple sweat potato flour, purple sweat potato, sensory test

Abstract

Fruits are a type of perishable agricultural product. One of the post-harvest handling efforts to maintain the freshness of the fruit is chitosan coating. Research has been carried out on various level concentration of chitosan as a coating for grapes (Vitis vinifera) and storage time. This study aims to determine the effect of chitosan concentration on water content,  color and brix of red grapes after storage. Chitosan coating was carried out by immersion methods at various levels of chitosan concentration, namely 0%, 0.5%, 1%, 1.5% and 2% (w/v) with immersion times of 30 seconds and 60 seconds. Based on the statistical test, it is shown that the chitosan concentration of 1.5% (w/v) with immersion time of 60 seconds and storage time on the 5th day is the most optimum for the brightness level of the grapes because the chitosan layer can close the pores of red grapes so that the respiration process aerobic and CO2 which affect color can be inhibited by chitosan solution. Keywords: Chitosan, edible coating, grape, post harvest, shelf life

Abstract

Jamur merang hasil panen Pondok Pesantren Anwar Futuhiyyah mudah mengalami penurunan mutu seperti pencoklatan, bertekstur lunak, beraroma tidak sedap, dan memiliki umur simpan yang pendek, Selain itu, jamur merang hasil panen tidak termanfaatkan semua sehingga mudah mengalami pembusukan. Pondok Pesantren Anwar Futuhiyyah bekerjasama dengan Program Studi Teknologi Hasil Pertanian UNU Yogyakarta dalam kegiatan pelatihan teknik pengemasan vakum dan pembuatan dimsum jamur merang (Volvariella volvacea). Produk jamur merang kemasan vakum dan dimsum jamur merang belum pernah ditemukan di pasaran sehingga berpotensi untuk dikembangkan. Pelatihan ini bertujuan agar para santri Pondok Pesantren Anwar Futuhiyyah mampu mempraktekkan teknik pengemasan vakum dan pembuatan dimsum jamur merang sehingga dapat memperpanjang umur simpan dan mempertahankan mutu jamur merang. Pelatihan ini dilakukan pada 16 November 2022 - 19 November 2022 yang diikuti oleh para santri yang berjumlah 40 orang. Kegiatan yang dilakukan meliputi survei lokasi, penyuluhan, pelatihan, dan evaluasi. Kegiatan ini telah menghasilkan luaran yang nyata yakni para santri telah mampu membuat jamur merang kemasan vakum dengan brand “Jamur Merang Blanching” dan dimsum jamur merang secara mandiri. Produk jamur merang kemasan vakum dan dimsum jamur merang dapat tahan kurang lebih 3 minggu jika disimpan di dalam freezer dalam kondisi beku. Jadi, permasalahan terkait jamur merang yang mudah mengalami penurunan mutu, memiliki umur simpan yang pendek, dan jamur merang yang tidak termanfaatkan seluruhnya dapat diselesaikan dengan baik oleh Pondok Pesantren Anwar Futuhiyyah.

Abstract

Infrared spectroscopy is a non-invasive analytical method that is particularly effective for evaluating the chemical makeup and physical quality of cocoa beans. It offers rapid results, minimal sample preparation, low operational costs, and is environmentally sustainable. However, only a limited number of studies have explored the use of infrared spectroscopy in cocoa. This study aims to investigate the research focus concerning the application of Infrared Spectroscopy Technology in cocoa commodities. The methodology employed includes a literature review with a bibliometric analysis approach and systematic literature review : identification, screening, eligibility, and inclusion. The data were collected from the Scopus database. The study results indicate an increase in publications related to the application of Infrared Spectroscopy Technology in cocoa commodities from 1988 to 2024, particularly from 2022 to 2023. Most research papers were published in Q1 journals, with Brazil leading in publications followed by other countries.New themes that emerge in research regarding related to infrared spectroscopy in cocoa include chemical structure, physicochemical properties, chemometrics, and thermogravimetric analysis. This research offers important insights into the present state and future prospects of infrared spectroscopy in cocoa analysis, emphasizing its importance in enhancing cocoa quality assessment and production efficiency in the chocolate industry. By exploring previous research, this study seeks to offer a deeper understanding of the role and potential of infrared spectroscopy technology. This paper conducts a bibliographic review of global studies related to technological applications of infrared spectroscopy in cocoa research, aiming to highlight worldwide scientific contributions and identify prevailing research trends in the field.
