Abstract

Tangerine (Citrus nobilis var. microcarpa) is most widely cultivated Citrus in Indonesia, it’s around 80% of all population of Citrus. Citrus can growth and cultivated in low land or upland (0-1500 m above sea level). Indonesia has extreme climate change (La Nina) in 2009 and 2010. Extreme climate change is one of the factors that affect the growth and productivity of citrus both in quality and quantity. Tangerine require 6-9 months of wet season and 3-6 months of dry season, although need enough water in dry season.  This research aims to study the effect of extreme climate change with high rainfall on phenology, productivity and quality of Tangerine in Banyuwangi, Jember and Lumajang. This Research was conducted at Tangerine center from 2005 until 2011 using observation method, the tangerine that use was from 5 years after planted until 12 years after planted. The Result showed that high precipitation occurred in 2010 (without dry season) affect the phenology cycle from 1-3 times in a year until 4-6 times in a year, but not become a fruit due high flower drop. It’s cause a decrease in Productivity form 20-30 ton/h until 5-10 ton/h and also a decrease in quality (color, flavor and total dissolved solid). The result also showed that PJTKS system (Integrated Management for Healthy Tangerine) can prevent a decrease in Tangerine Productivity (10-12 ton/h). This Research also obtained that dry land and sandy land has potential for cultivation of tangerine that originally grown in paddy field.

Abstract

Studi pola konsumsi buah nasional sebelum dan di awal masa pandemi Covid-19 perlu dilakukan sebagai langkah awal inventarisasi ada atau tidaknya pergeseran, agar strategi dan antisipasi pembenahan dapat dirancang sejalan dengan upaya mewujudkan ketahanan dan keberlanjutan pangan. Empat ratus enam puluh enam responden terlibat dalam studi ini, melalui survei yang dilaksanakan secara daring. Metode analisis deskriptif, uji tanda, dan Fishers exact test digunakan. Hasil studi mengindikasikan adanya pergeseran pola konsumsi sebelum dan pada awal masa pandemi covid-19 untuk lima atribut, yaitu (1) dana alokasi pengeluaran buah per bulan, (2) frekuensi pembelian, (3) tempat, (4) kesulitan dalam perolehan, dan (5) jenis buah nasional yang dikonsumsi. Pergeseran ini menjadi isyarat perlunya upaya peningkatan kesadaran konsumsi buah nasional untuk menjaga imunitas dan krusialnya sinergi antara produsen dan distributor akan rantai pasok yang efisien dan efektif, serta penggunaan platform digital. Pembenahan diharapkan membuat konsumen dapat menikmati buah nasional berkualitas dari rumah dengan harga yang terjangkau. Segmentasi demografis berdasarkan kelompok umur dapat menjadi pertimbangan penyedia, karena memiliki hubungan yang signifikan dengan atribut pola konsumsi kedua sampai kelima. Studi lebih lanjut diperlukan untuk memotret dampak pergeseran terhadap supply dan value chain.KeywordsDaring; Imunitas; Preferensi konsumen; Rantai pasok; SinergiAbstractStudies of national fruit consumption patterns before and at the beginning of the Covid-19 pandemic period need to be carried out as an initial step for improvement to achieve food sustainability. A total of 466 respondents were involved in the survey which was conducted online. Descriptive analysis, sign test, and Fishers exact test were used. The results indicated there was a shift in consumption patterns before and at the beginning of the Covid-19 pandemic period, in terms of (1) expenditure allocation for fruit per month, (2) frequency, (3) place of purchase, (4) difficulties in procurement, and (5) types of national fruit consumed. The shift is a sign of the need for efforts to increase awareness of national fruit consumption. The synergy between producers and distributors to form an efficient and effective supply chain, and the use of digital platforms, is crucial, so that consumers can enjoy high quality national fruit from home at affordable prices. Demografic segmentation based on age group can be considered by providers, because it has a significant relationship with the second to fifth consumption pattern attributes. Further studies are needed to capture the shift impact on the supply and value chain.

Abstract

The Consumer Acceptance of Local Citrus Drink in Batu-East Java Fruit juice products in Indonesia are still dependent on imported raw materials. This situation needs to be our concern, considering that Indonesian citrus have many varieties and qualities that are not inferior to imported fruit. Therefore, a study was conducted on consumer acceptance of local citrus juice produced in Indonesian Citrus and Subtropical Fruits Research Institute (ICSFRI) using raw materials of four local mandarin varieties, namely Satsuma, Batu 55, JRM and Terigas. Eighty-seven respondents participated in this survey that held in July 2019. Product satisfaction and performance were analyzed using the CSI and IPA methods. Respondent consumptions patterns were also seen to find out the initial description of the quantity and benefit that were sought by consumers of citrus drinks. The results showed that the most preferred processed products from citrus were drinks, with consumption pattern of 1-2 times (37,9%) and 3-4 times (31%) each month. Here, health becomes the main reason for consuming this product. From the analysis, it is illustrated that all respondents received well the three local citrus juice (Terigas, Satsuma, JRM) products, where quality improvement still needs to be done. Citrus varieties that become the main recommendation is Terigas citrus because it’s fulfilled three main citrus juice attributes (citrus flavor, aroma and color) and have the highest customer satisfaction value. This is also supported by the higher vitamin C content, which is needed to increase body immunity, especially in this pandemic era. Keywords: customer satisfaction index (CSI), fruit juice, local citrus, index performance analysis (IPA), vitamin CABSTRAKProduk sari buah di Indonesia masih menggantungkan bahan baku produknya dari buah impor. Hal ini menjadi perhatian, mengingat jeruk Indonesia memiliki beragam varietas dan kualitas yang tidak kalah dengan buah impor. Oleh karena itu dilakukan studi terhadap penerimaan konsumen akan minuman sari buah jeruk lokal yang diproduksi di Balai Penelitian Tanaman Jeruk dan Buah Subtopika (Balitjestro) dengan menggunakan bahan baku empat varietas jeruk keprok lokal, yakni jeruk Satsuma, Batu 55, JRM dan Terigas. Delapan puluh tujuh responden berpartisipasi dalam survei yang diadakan bulan Juli 2019. Kepuasan dan kinerja produk dianalisis menggunakan metode CSI dan IPA. Pola konsumsi responden juga dilihat untuk mengetahui gambaran awal kuantitas dan manfaat yang dicari oleh konsumen minuman sari buah jeruk. Hasil penelitian menunjukkan bahwa produk olahan dari jeruk yang paling disukai adalah minuman, dengan pola konsumsi 1-2 kali (37,9%) dan 3-4 kali (31%) setiap bulannya serta kesehatan sebagai alasan utama dalam mengkonsumsi produk ini. Dari analisis tergambar bahwa keseluruhan responden menerima dengan baik tiga produk sari buah jeruk lokal, dimana peningkatan kualitas masih perlu dilakukan. Varietas jeruk yang menjadi rekomendasi utama adalah jeruk Terigas, karena telah memenuhi tiga atribut utama (rasa jeruk, aroma, dan warna) serta memiliki nilai kepuasan konsumen paling tinggi. Hal ini juga ditunjang dengan kandungan vitamin C yang lebih tinggi untuk meningkatkan imunitas tubuh, terutama di era pandemi ini.Kata kunci: customer satisfaction index (CSI), index performance analysis (IPA), jeruk lokal, sari buah, vitamin C

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Postharvest technology is needed so that the abundant citrus fruits at harvest time can be utilized and at the same time can increase the added value of these oranges. The potential to increase the added value of Indonesian citrus products is still huge. The processing of oranges into fruit juice drinks can be one way to increase the added value of oranges. Orange juice is currently a trendy drink as it contains vitamin C, which increases the human body's immunity in the pandemic era. The study aims to determine the effects of several types of stabilizers addition with several formulations on the physical and chemical characteristics, as well as sensory properties of the panellists' preference for Keprok Terigas juice. This study made use of Completely Randomized Design (CRD) with two factors, the first factor was the type of stabilizer (CMC, xanthan gum, arabic gum) and the second factor was the concentration of the stabilizer (0.025%, 0.05%, 0.075%, 0.1%). Results of the study indicated that vitamin C contained in the citrus fruit juice ranged from 13.49 to 24.69 mg/100 grams. Citrus fruit juice had a total dissolved solid value of 11.10 -12.63, pH was 3.535-3.787, total acid was 4.567-7.433 and viscosity value of 4.167-43.500 cp. The treatment of several types of stabilizers affected the value of vitamin C content, viscosity, and total dissolved solids, yet it gave no affect on the pH of the citrus juice.

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Ice cream products made of orange juice may increase the added value of the products. Besides, vitamin C contained in the oranges also contributes to human’s health. The study aims to determine effects of differences in the citrus varieties and the proportion of water compared to orange juice on the overrun value, total dissolved solids, melting rate, vitamin C content, sensory properties of scoring and the panellist’s preference for orange ice cream. The study was designed using Completely Randomized Design with two factors, namely differences in citrus varieties (Siam Pontianak and Keprok Terigas) and the  proportion of orange juice compared to water (1:2; 1:1; 2:1). The results show that the Keprok Terigas ice cream had the highest preference value on the parameters of colour, aroma, taste and texture compared to those of Siam orange ice cream. The highest content of vitamin C was obtained from Siam orange ice cream in the proportion of orange juice compared to water 1:1, vitamin C content was 48.40 mg/100 grams. Total dissolved solids of the orange ice cream ranged from 2.267 – 2.600, pH was between 4.933 – 6.180, the overrun value was between 52.320 – 56.780% and melting rate was between 790.1 - 884.5 seconds. The differences between the Keprok Terigas and Siam Pontianak varieties have affect the value of vitamin C, pH, and overrun. The treatment of the proportion of orange juice: water affected the pH value, total dissolved solids, and overrun, but did not affect the melting rate.
