Abstract

ABSTRACTThe perception of tourists is needed as a consideration in efforts to develop iconic local food products in Bromo. The study aims to determine tourists' perception to develop iconic local food products in Bromo, including authenticity, raw material sources, production, and sales locations. A quantitative research method was used to survey 405 tourists who had visited the Bromo area between 2017 and January 2023. Results show that tourists are not concerned with the authenticity of local food products in Bromo as long as they are made from local ingredients, produced, and sold in Bromo. However, tourist acceptance decreases if the product does not use local raw materials or is not produced in Bromo. The findings can be used to develop small and medium-sized food industry businesses that improve the image of local cultural heritage food among the Tengger community by enhancing quality and standardization, reducing food waste and loss, adding variety, and managing waste.ABSTRAKPersepsi wisatawan dibutuhkan sebagai pertimbangan dalam upaya pengembangan produk makanan lokal Ikonis Bromo. Tujuan penelitian ini untuk mengetahui persepsi wisatawan terhadap keautentikan, sumber bahan baku, lokasi produksi, hingga lokasi penjualan produk makanan yang berpotensi untuk dikembangkan sebagai makanan lokal Ikonis Bromo. Metode penelitian kuantitatif digunakan untuk menyurvei 405 orang wisatawan berusia 15 tahun ke atas yang pernah datang ke kawasan Bromo antara tahun 2017 hingga Januari 2023 dengan menggunakan kuesioner. Hasil menunjukkan bahwa para wisatawan tidak mempermasalahkan keautentikan produk pangan lokal Bromo selama bahan baku yang digunakan merupakan bahan baku lokal, serta produk tersebut diproduksi dan dijual di Bromo. Sebaliknya, penerimaan wisatawan menurun jika produk pangan tersebut tidak berbahan baku lokal atau tidak diproduksi di Bromo. Hasil penelitian ini diharapkan dapat diimplikasikan pada pengembangan UMKM industri pangan yang dapat meningkatkan citra makanan lokal warisan budaya masyarakat Tengger melalui peningkatan kualitas dan standarisasi rasa, kebersihan, dan keamanan, mengurangi food waste and loss, penambahan variasi, hingga pengelolaan limbah.

Abstract

Xanthosoma sagittifolium or tannia cocoyam (TC) is a root vegetable that grows in Java. Its corm can be used as flour to increase the use of TC. However, one major issue is that TC corm flour is less elastic than wheat flour. Nonetheless, modifications such as gaplek fermentation may be implemented to enhance the characteristics of TC flour. However, the microorganisms that contribute to the processing of gaplek through natural fermentation have never been characterized. This study focuses on the isolation and identification of microorganisms that play a role in the gaplek fermentation of TC. The methods used to determine these microorganisms included counting the total bacteria using Total Plate Count, identifying lactic acid bacteria using selective media De Man, Rogosa, and Sharpe Agar, as well as fungi and yeast using selective media Potato Dextrose Agar. Other tests that were conducted were motility test, catalase test, and carbohydrate fermentation test using seven different sugars, i.e., arabinose, dextrose, lactose, maltose, mannose, rhamnose, and sucrose. Sampling was conducted on dried TC chips and soaked TC chips at 0 hours and 48 hours. The results revealed the thriving of lactic acid bacteria after 48 hours of wet fermentation, which were suggested as Lactococcus and Leuconostoc. In addition to lactic acid bacteria, other microbes such as yeast and non-pathogenic Staphylococcus were also identified.

Abstract

Pembangunan pariwisata di kawasan Bromo berpotensi merusak budaya Tengger akibat masuknya budaya asing yang dibawa wisatawan, seperti tergilasnya pangan warisan budaya Tengger oleh jenis makanan yang lebih populer dikenal wisatawan. Peran industri pangan penting untuk mendukung citra pangan warisan budaya Tengger, antara lain meningkatkan kapasitas produksi, sanitasi, keamanan, standar kualitas, umur simpan, dan penanganan limbah makanan. Permasalahan yang dihadapi adalah kesiapan sumber daya manusia hingga teknologi masyarakat Tengger serta seberapa jauh kesediaan masyarakat Tengger dalam menyerap perkembangan zaman tanpa mengubah adat budaya tradisional mereka. Penelitian ini bertujuan untuk mengetahui persepsi masyarakat Tengger yang tinggal di Desa Wonokitri, Pasuruan, terhadap potensi pengembangan industri pangan di sana. Metode penelitian yang dipilih adalah penelitian kuantitatif secara sampling kuota terhadap 400 orang penduduk Desa Wonokitri di Pasuruan dengan menggunakan kuesioner. Ditemukan bahwa meskipun mayoritas responden berpendapat bahwa industri pangan sangat mungkin untuk didirikan di Wonokitri, kurangnya minat penduduk dan kurangnya keterampilan menjadi penghambat yang paling utama. Selain itu, kurang dari separuh responden terjangkau penyuluhan dan kurang dari seperempatnya terjangkau bantuan modal pemerintah. Temuan penelitian ini dapat dimanfaatkan untuk pengembangan pariwisata Bromo yang berkelanjutan, baik untuk konservasi alam maupun konservasi budaya Tengger.

Abstract

Aron is a fermented white corn, a traditional product of the Tengger tribe, which is susceptible to contamination by pathogenic microorganisms during its production process. The addition of starter cultures obtained from the isolation of dominant lactic acid bacteria in the natural fermentation of white corn, namely Lactobacillus and Streptococcus, was expected to inhibit the growth of pathogenic microorganisms. The aim of this study was to evaluate the ability of different concentrations of starter culture, starting from 0%, 10%, 20%, and 30% to inhibit the growth of pathogenic microorganisms, under different fermentation conditions, which are traditional fermentation at a cold temperature around 13-18°C in Tengger and controlled fermentation at 28-32°C in a laboratory in Surabaya for 6 days, with analysis done on days 0, 3, and 6. Differences in sensory characteristics of aron with the addition of starter cultures, including aroma, taste, and color, were also evaluated. The indicator used to measure the growth of pathogenic microorganisms was Enterobacteriaceae, which quantity was analyzed to evaluate the inhibition of its growth by lactic acid bacteria under both conditions. Biochemical analyses such as TSIA test, catalase test, and motility test were performed to ensure that the dominant bacteria at the end of fermentation were lactic acid bacteria. Additionally, molds that grew during fermentation in both conditions were identified. Sensory analysis was done at the end of fermentation, including aroma, taste, and colour tests, which supported by Whiteness Index, DE2000, and Chroma analyses to evaluate the impact of starter culture and environmental conditions on the resulting aron. The addition of starter cultures was shown to affect the inhibition of Enterobacteriaceae growth under both conditions. Biochemical tests serve as supporting evidence that the dominant bacteria under both conditions after 6 days of fermentation were lactic acid bacteria. Aroma was identified as an attribute likely influenced by the addition of starter culture and environmental differences, caused by the compounds produced during fermentation. It was concluded that the addition of starter culture and environmental differences affect the microbiological characteristics and aroma of aron.

Abstract

Aron, a traditional fermented food of the Tengger community, is made from white corn grown in Bromo and has received limited microbiological, chemical, and sensory research attention to date. The research objective was to compare microbiological, chemical, and sensory traits between in situ-produced aron on the slopes of Mount Bromo and ex situ-produced aron in a laboratory in Surabaya. A specific strain of lactic acid bacteria was isolated using de Man, Rogosa, and Sharpe (MRS) Agar from samples of sun-dried white corn. This strain was identified as Gram-positive cocci. In contrast, a different strain of Gram-positive bacilli was found in corn-soaking water, both in situ and in laboratory-fermented aron, on days 0, 7, and 16. Chemical analysis revealed no significant differences in protein, fat, and ash content between the two variables. However, laboratory-fermented aron exhibited higher moisture content. This discrepancy significantly influenced the hedonic texture data for aron, with in situ aron being perceived as drier and more mouth-soluble, while laboratory-fermented aron had a softer texture. Furthermore, the high microbial growth during the fermentation process resulted in aron with a distinct and relatively strong aroma that was less favored by the panelists. The difference in the fermentation location of white corn did not affect the types of lactic acid bacteria that thrived, the nutritional compound content, and the appearance of aron. The variation in the aroma of aron is believed to be primarily influenced by the number of bacteria rather than their specific strains.

Abstract

Yogurt is one of the many variations of fermented milk food products that has a fairly high viscosity. Yogurt is classified as a functional food product because of its complete nutritional content and impact on the human digestive health system. The current condition of yogurt products is experiencing several developments, such as yogurt fortification with fruit extract to improve the quality of organoleptic yogurt. Not only does this addition affect the sensory quality, but it also decreases the pH value as well as increases the viscosity and the starter's viability. Moreover, fruit extract also increases yogurt’s functional characteristics through the enhancement of antioxidant content and activities. The changes and impact that are done to yogurt is influenced by several content which are found in the fruit extract that are added. Fruit extract’s compound contents affect and influence the microbial starter growth and metabolism activity, which is impactful towards changes in the quality characteristics of the resulting yogurt.

Abstract

A herbal beverage mixture based on extracts of turmeric (Curcuma longa), Javanese turmeric (Curcuma xanthorrhiza), and red ginger (Zingiber officinale) with a ratio of 8:6:3 was developed as an isotonic beverage after describing its sensory characteristics and antioxidant properties. Three different dilutions (1:10, 1:15, and 1:20) were used for sensory acceptance testing by consumers. Antioxidant activity tests using DPPH followed by HPLC were conducted on each extract as well as the most concentrated dilution and the best treatment. The sensory testing results indicated that the 1:20 dilution treatment was the most acceptable. The DPPH results showed that the 1:10 and 1:20 dilutions had inhibition activities of 52.34% and 37.94% respectively, which correlated with the quantification of curcumin using HPLC, namely 167.47 µg/g and 125.06 µg/g. The higher the curcumin content, the higher the DPPH inhibition activity. Atomic absorption spectroscopy (AAS) analysis revealed that the Na and K content in the 1:20 diluted herbal beverage were 11.66 mg/kg and 13.85 mg/kg respectively, which were still lower than the standard SNI-01-4452-1998. Therefore, the isotonic beverage was formulated by adding low-sodium salt and sodium citrate as sources of sodium, potassium, and citrate.

Abstract

Gluten allergy has raised concerns due to its impact on health, especially as wheat noodles are widely consumed. The growing demand for gluten-free alternatives highlights the need for suitable substitutes. This study investigates the effects of fermentation modification on the amylose and protein content of tannia cocoyam flour and evaluates the impact of modified tannia flour and xanthan gum on the physicochemical and sensory properties of noodles. Fermentation of tannia cocoyam (Xanthosoma sagittifolium) corm flour using 9% Lactobacillus plantarum starter over 48 hours enhanced the characteristics of tannia cocoyam noodles. However, despite these improvements, the noodles remained brittle and lacked the desired chewiness compared to conventional noodles. The introduction of xanthan gum as a binding agent was used to improve noodle attributes. Various xanthan gum concentrations (0%, 1%, and 2%) were assessed for their impact on physicochemical parameters (color, optimal cooking time, rehydration capacity, cooking loss, and elongation) and sensory preferences. The findings revealed that modification of tannia cocoyam flour using the fermentation method influenced noodle color, while different xanthan gum concentrations had no discernible effect. Furthermore, modification of tannia cocoyam corm flour and the specific xanthan gum formulations influenced cooking loss, elongation, and the preferences of the panelists.
