Abstract

Xanthosoma sagittifolium starch has the potential to be developed as a base for edible film, because it was hydrocolloid compound, as well as renewable natural resources, widely available and easy to obtain its. High amylose content of X. sagittifolium starch (35.34%), twice than cassava starch, so that it possible to produce strong and flexible edible film. The presence of the active ingredient in edible film with different it kinds and amounts would produce different properties too. The purpose of this study was to evaluate the physical, mechanical and barrier properties of active edible film due to variation of concentration of starch and potassium sorbate. Edible films have produced characteristics for tensile strength from 0.399 to 1.390 MPa, elongation from 14.943 to 31.647%, thickness from 0.065 to 0.081 mm, water vapor transmission rate from 10.095 to 15.247 g.mm/m2.day, solubility from 27.126 to 59.846% and transparency from 0,719 to 1,063. To increase starch made elevation of edible film tensile strength, thickness, WVTR, and the smoothness, as well as decrease its water solubility, while increasing potassium sorbate would increase elongation and WVTR, as well as decrease the tensile strength. ABSTRAKPati umbi kimpul (Xanthosoma sagittifolium) mempunyai potensi untuk dikembangkan sebagai bahan dasar edible film, karena pati merupakan senyawa hidrokoloid, sebagai sumber daya alam yang dapat diperbaharui, tersedia secara luas dan mudah didapat. Kandungan amilosa pati umbi kimpul cukup tinggi (35,34%), dua kali lebih besar dibandingkan amilosa pati ubi kayu, memungkinkan untuk menghasilkan edible film yang kuat dan fleksibel. Keberadaan kalium sorbat dalam edible film dengan jumlah yang berbeda akan menghasilkan sifat yang berbeda pula. Tujuan penelitian ini adalah untuk mengetahui sifat fisik, mekanik dan barrier edible film aktif akibat variasi konsentrasi pati umbi kimpul dan kalium sorbat. Edible film yang dihasilkan mempunyai karakter kuat tarik 0,399-1,390 MPa, persen pemanjangan 14,943-31,647%, ketebalan 0,065-0,081 mm, WVTR 10,095-15,247 g.mm/m2.hari, kelarutan 27,126-59,846% dan transparansi 0,719-1,063. Penambahan pati menyebabkan kuat tarik, ketebalan, laju transmisi uap air, dan kehalusan permukaan edible film meningkat, tetapi kelarutannya dalam air menurun, sedangkan penambahan kalium sorbat dalam edible film menyebabkan persen pemanjangan dan laju transmisi uap air meningkat, tetapi kuat tariknya menurun.

Abstract

A study on the design of metering device which could work more optimally was conducted to overcome the high friction between the rotor and its metering tube, and the clogging of fertilizer particle on the conventional rotor type metering device. An edge-cell rotor type metering device was proposed to overcome the problems. Objectives of the study were to analyze the torque requirement of the edge-cell type metering device and to design metering device of corn fertilizer applicator with lower torque requirements and high accuracy. A mathematical model to calculate the torque requirement of the rotor was developed and validated using torque measurement in the experiment. Experiments were conducted using a model of fertilizer applicator equipped with a rotor torque measuring sensor and rotated using an electric motor. The torque measurement results showed that the edge-cell type metering device could reduce the torque requirement up to 68% and 80% when tested using urea and TSP, respectively. By using the edge-cell type rotor, there was no problem of clogging of fertilizer particle on the rotor system. The validation results showed that the mathematical model could predict accurately the torque requirement of the rotor only on the lower volume of fertilizer (25%) in the hopper. However, on the higher volume of fertilizer (50% and 100%) in the hopper, the calculated torques was 2-4 times higher than the actual measuring torques. The amount of the fertilizer in the hopper not significantly affected the torque requirement of the rotor.ABSTRAKPenelitian mengenai desain penjatah pupuk yang dapat berfungsi lebih optimal dilakukan untuk mengatasi besarnya gaya gesek yang terjadi antara rotor penjatah dan ruang penjatah, serta terjadinya kemacetan perputaran rotor penjatah pupuk pada alat pemupuk dalam penelitian sebelumnya. Tujuan penelitian ini adalah menganalisis kebutuhan torsi penjatah pupuk tipe edge-cell. Model pendugaan matematis untuk menghitung kebutuhan torsi telah dibangun dan divalidasi melalui pengujian kebutuhan torsi. Pengukuran dilakukan enggunakan model alat pemupuk jagung yang dilengkapi dengan sensor pengukur torsi. Penjatah tersebut diputar menggunakan motor AC variable speed. Hasil pengukuran torsi menunjukkan bahwa penjatah tipe edge-cell mampu mengurangi kebutuhan torsi penjatahan hingga 68% (pupuk urea) dan 80% (pupuk TSP). Kemacetan yang terjadi akibat ganjalan butiran pupuk yang besar pada ruang penjatah tidak terjadi saat menggunakan penjatah tipe edge-cell. Hasil pengujian validasi model menunjukkan bahwa model matematis mampu menduga kebutuhan torsi dengan akurat hanya pada saat tingkat volume pupuk dalam hopper 25%. Semakin tinggi volume pupuk dalam hopper (50 dan 100%), hasil pendugaan torsi lebih besar sekitar dua hingga empat kali hasil pengukuran torsi. Volume pupuk dalam hopper tidak berpengaruh signifikan terhadap kebutuhan torsi pada rotor.

Abstract

anthocyanin pigments are responsible for the red, blue, and purple colour in crop produces such as fruits, vegetables, rice, and flowers. This bioactive compound has been developed for natural colorants in food products, especially functional foods. The aims of this research were to study the stability of anthocyanin and its colour during heating in various temperatures and during storage under different conditions. The results showed that the higher the heating temperature and the longer the heating time, the higher degradation of anthocyanin. Except for anthocyanin extract heated below 50 c for not more than 15 min, it has increased the anthocyanin stability. antioxidant activities (% RSa, radical scavenging activity and fRaP value, Ferrous Radical Activity Power) decreased after the extract were heated at 70c. Extracts stored at room temperature with neutral solution (pH 7.0) have decreased their level of anthocyanin from 25 to 1.87 mg/100 mL. Storage at low temperature had not reduced significantly their anthocyanin concentration. ABSTRAKAntosianin sebagai senyawa yang menyebabkan timbulnya warna merah, biru, dan ungu pada padi, buah, sayuran, dan produk hortikultura lainnya, sangat berpotensi untuk dikembangkan sebagai bahan pewarna alami pada produk pangan fungsional. Tujuan dari penelitian ini adalah untuk mempelajari stabilitas dan warna ekstrak antosianin dari beras ketan hitam selama proses pemanasan dan penyimpanan. Hasil menunjukkan bahwa semakin tinggi suhu pemanasan dan semakin lama waktu pemanasan, menyebabkan kerusakan antosianin semakin banyak. Kecuali pada pemanasan <50 c tidak lebih dari 15 menit yang dapat meningkatkan kestabilan antosianin. aktivitas antioksidan (% RSa, radical scavenging activity dan nilai fRaP, Ferrous radical Activity Power) mengalami penurunan setelah dipanaskan pada suhu 70 oc. Penyimpanan pada suhu kamar dan pH 7,0 dapat menurunkan kadar antosianin ekstrak dari 25 menjadi 1,87 mg/100 mL. Sedangkan penyimpanan pada suhu rendah tidak menyebabkan perubahan kadar antosianin yang berarti.
