Abstract

The Covid-19 pandemic that has occurred since March 2020 has caused a recession in the Indonesian economy. Unlike the economic crises in 1998 and 2008 in Indonesia, the economic crisis in 2020 due to the Covid-19 pandemic affected almost all sectors and threatened the existence of MSMEs. This study aims to determine the impact of the Covid-19 pandemic on MSMEs in DKI Jakarta, identify and classify MSMEs during the Covid-19 pandemic and provide alternative solutions and strategies for MSME actors in dealing with the economic crisis due to the Covid-19 pandemic. The study was conducted on MSMEs in DKI Jakarta with a total sample of 1,511 respondents. The research was conducted through qualitative and quantitative approaches with descriptive statistical data analysis techniques and SWOT analysis. The results showed as many as 83% of MSMEs experienced a decrease in business circulation, with the classification of a decrease in business circulation of up to 50% by 48%, and the remaining 35% experiencing a decrease in business circulation of more than 50%. As many as 83% of MSMEs experienced a decline in business circulation, which was dominated by micro-businesses in the trade, hotel, and restaurant sectors, with an average age of 0-5 years. The MSME recommendation strategy was prepared through a SWOT analysis and an in-depth assessment of internal and external factors referring to the MSME main recommendation strategy through a Cartesian diagram.

Abstract

Bekatul atau rice bran adalah lapisan luar dari beras yang terlepas pada saat proses penyosohan dari beras pecah kulit menjadi beras. Salah satu kendala peneriman konsumen pada bekatul adalah mutu sensorinya. Oleh sebab itu, salah satu upaya untuk meningkatkan mutu sensori bekatul dilakukan dengan fermentasi. Tujuan penelitian ini adalah mengetahui pengaruh jenis kapang, varietas bekatul (padi), dan lama fermentasi terhadap perubahan kandungan total senyawa fenolik (TSF), aktivitas antioksidan, dan profil sensori bekatul fermentasi dari dua varietas padi (Sintanur dan Inpari 24). Fermentasi dengan metode Solid-state fermentation menggunakan perlakuan jenis kapang yaitu Rhizopus oligosporus, R. oryzae dan kombinasi keduanya, dengan lama waktu fermentasi masingmasing adalah 48, 72 dan 96 jam. Analisis kandungan TSF dengan metode Folin-ciocalteu, analisis aktivitas antioksidan menggunakan metode DPPH, dan analisis profil sensori menggunakan metode Projective mapping (Napping®) dengan panelis tidak terlatih berjumlah 75 orang. Hasil penelitian menunjukkan bahwa perlakuan varietas padi, jenis kapang dan waktu fermentasi menghasilkan nilai TSF dan aktivitas antioksidan yang berbeda nyata (p<0,05). Bekatul Inpari 24 memiliki nilai TSF dan aktivitas antioksidan yang lebih tinggi dibandingkan bekatul Sintanur (p<0,05). Nilai TSF dan aktivitas antioksidan tertinggi pada bekatul Inpari 24 yang difermentasi dengan kapang R.oligosporus selama 48 jam dengan nilai masing-masing sebesar 4,16±0,3 mg GAE/g BK dan 86,11 %. Selanjutnya, hasil analisis korelasi menunjukkan korelasi positif antara kandungan TSF dan aktivitas antioksidan kedua varitas bekatul fermentasi (r=0,82). Analisis sensori menunjukkan bahwa panelis mampu membedakan atribut sensori pada sampel yang diujikan.

Abstract

Fermentation of cocoa beans can produce flavour precursors and colour changes in chocolate. Generally, this process is carried out for 5-7 days without adding starter culture. Adding a starter culture is considered to improve the quality of cocoa beans and shorten the fermentation time. The purpose of this study was to compare the starter cultures used in the cocoa bean fermentation process through a meta-analysis approach. Twenty-four related articles have been screened from the initial number of 110 articles. There are five starter cultures and six parameters that can be processed by Confidence Interval (CI) analysis. Calculating p and I2 values ​​using STATA software was performed to see variations between studies and test the significance of their effects during the fermentation process through p values. The variation test between studies showed that the profiles of lactic acid bacteria (LAB) and acetic acid bacteria (AAB) were heterogeneous. While the yeast profile, levels of lactic acid, acetic acid and pH between studies are homogeneous. The results of the study showed that the addition of starter culture will affect the levels of yeast profile (ES: 0.470; 95% CI: 0.371 to 0.569; p = 0.0); LAB profile (ES: 0.747; 95% CI: 0.600 to 0.894; p = 0,0); AAB profile (ES: 0.808; 95% CI: 0.663 to 0.953; p = 0.0); lactic acid (ES: -0.003; 95% CI: -0.162 to 0.156; p = 0.039); acetic acid (ES: 0.189; 95% CI: 0.01 to 0.368; p = 0.039) and pH (ES: 0.109; 95% CI: 0.001 to 0.218; p = 0.049). Using pure starter cultures can increase the number of microbes of the type added and increase metabolic activity by showing a decrease in acetic acid levels in cocoa beans at the end of the fermentation process. However, no changes were seen in pH or lactic acid levels.

Abstract

The demand for organic food in Indonesia is increasing annually. Organic rice is one of the most consumed organic foods in Indonesia. Organic rice perceive as healthier than conventional rice; however, in the context of the food system (from farm to fork), is organic rice better than conventional rice? To what extent does the transition contribute to sustainability? We have been investigating organic rice in the context of the food system since 2016. Our experiment reveals that (1) organic rice fits the organic principle in the level of farming where less pesticide, better farmer income and protecting biodiversity (2) lower degree of milling in organic rice resulted in the highest nutritional benefit (3) consumer perception depend on nutritional information From this point of view, we conclude that organic rice would be fit for the organic food principle and sustainable way if the rice has a lower degree of milling.

Abstract

Abstract— Tempe is a traditional indigenous fermentation food from Indonesia. The addition of rice bran as raw material for soybean mixture aims to improve functional properties of tempe. The sensory description and sensory mapping of four formulations rice bran tempe were measured. Seventy-five consumers were recruited to participate in the projective mapping of rice bran tempe cookies at the sensory laboratory of Universitas Bakrie, one of the private universities in Indonesia. The test consists of a descriptive evaluation of products with sensory attributes: taste, color, flavor, texture and aftertaste. Data was used to develop a preference map for rice bran tempe cookies. The cookies formulation consist of rice bran tempe without any addition (RBT1), rice bran tempe with cocoa powder (RBT2), rice bran with dates extract (RBT3), and rice bran tempe with cocoa powder and dates extract (RBT4). Results from preference mapping showed that the position for each rice bran tempe cookies formulation show differently with commercial products. The map shows RBT1 and RBT2 cookies have higher consumer preferences (elevation 40) than RBT3 cookies (elevation 30) or RBT4 cookies (elevation 20). Average overall acceptance scores for the four samples ranged from 4.37 to 4.81 on a 1-9 scale. The addition of rice bran tempe to the cookies formulation has not been accepted by the consumers due to the sensory attributes of bitter taste, dark color, aroma like animal feed, hard texture and bitter aftertaste. The presence of cocoa powder and dates extract has not been able to increase consumer preference of the tempe rice bran cookies.

Abstract

Chocolate drinks are widely consumed due to their rich flavor and polyphenol content. Previous research has highlighted the flavor richness and high polyphenol content of Arabica coffee. This study aims to examine the effects of adding Arabica coffee on the physical characteristics and sensory profiles of chocolate drinks. The composition of the chocolate drinks used in this study includes fermented cocoa powder, Java Preanger Arabica coffee powder, Cascara Arabica, and stevia sweetener. Physicochemical analysis methods encompass color testing, pH measurement, and total soluble solids (TSS) determination. The five tested formulations resulted in a slightly dark yellowish-red color, with pH values ranging from 5.82 ± 0.10 to 6.22 ± 0.08, and TSS content ranging from 5.17 ± 0.76 to 5.90 ± 0.46. In addition to physicochemical analysis, sensory analysis was conducted using the Check-All-That-Apply (CATA) method facilitated by XLSTAT. Although no formulations matched the ideal product, the most preferred formulation consisted of 80% cocoa and 20% coffee, attributed to its sweet flavor. With lower percentages of coffee addition, attributes such as chocolate flavor, sweetness, caramel flavor, and milk flavor became more prominent in the chocolate drinks.
