Abstract

This study aims to determine the effect of using tapioca flour in the manufacture of fish crackers and determine the moisture content, ash content, texture of the analyzer, protein content and organoleptic test of oci fish crackers. The method used in this study was a simple completely randomized design (CRD) method with three replications with fish formulation of 175 g oci + 75 g tapioca flour, 125 g of oci fish + 125 g of tapioca flour with 125 g of oci fish + 125 g of tapioca flour and fish oci. 75 g + 175 g of tapioca flour, namely with 75 g oci fish formulation + 175 g tapioca flour. The results of the analysis of variance showed that the addition of tapioca flour had a significant effect on water, ash, protein, and garnish content. The organoleptic test results showed that the three treatments for aroma parameters were very favorable, grayish white color, slightly crunchy texture, and slightly preferred taste.

Abstract

The popularity of herbal products in Indonesia during the COVID-19 pandemic has risen recently. It is believed to be preventive measures to lower the probability of COVID-19 infection and boost immunity. This study explored the knowledge of the Java Island population about COVID-19 and their belief about herbal products and supplements consumption for the prevention of COVID-19 infection. A total of 485 respondents participated in this research. About 84.7% (n = 411) of the participants claimed that they had used herbal products or supplements before the pandemic. Recommendations from friends or relatives (51.1%, n = 248) were the main reason for the respondents to consume herbal products or supplements. Multivitamins (19.6%, n = 95) were the most commonly chosen supplement to increase immunity and reduce the chance of COVID-19 infection. The governments are suggested to provide more evidence-based campaigns to increase population awareness about the use of herbal products and supplements to ensure patient safety.

Abstract

Tujuan dari penelitian ini adalah 1) untuk mengetahui pengaruh komposisi media tongkol jagung terhadap pertumbuhan tanaman zinnia, 2) untuk mengetahui pengaruh konsentrasi air cucian beras terhadap pertumbuhan tanaman zinnia dan 3) untuk mengetahui interaksi komposisi tongkol jagung dan air cucian beras terhadap pertumbuhan tanaman zinnia. Penelitian ini berlangsung dari bulan Oktober hingga Desember 2019. Penelitian ini menggunakan rancangan factorial dua faktor (F2F) dalam RAK dan diulang sebanyak 3 kali. Faktor pertama adalah komposisi media tanam yaitu ; tanah : pupuk kandang : tongkol jagung (M); yang terdiri dari 3 taraf antara lain; M1 = 2:2:2 ; M2 = 2:1:1 ; dan M3 = 1:1:1. Faktor kedua adalah konsentrasi air cucian beras (P) yang terdiri 4 taraf yaitu; P0 = control ; P1 = 50% ; P2 = 75% ; P3 = 100%. Hasil yang diperoleh adalah komposisi media tanam dan konsentrasi air cucian beras tidak memberikan pengaruh yang nyata terhadap pertumbuhan tanaman zinnia, sedangkan Interaksi antar keduanya memberikan pengaruh yang nyata terhadap perttumbuhan tanaman zinnia pada parameter jumlah daun tanaman terbanyak terdapat pada perlakuan komposisi media tanam 2:2:2 dengan pemberian air cucian beras 75%.

Abstract

Catfish manure, goat manure, cow urine and lamtoro leaves are organic materials that are easily obtained and have not been used optimally. To utilize this material, it can be made into liquid organic fertilizer to make it easier to apply and make combinations in order to increase the growth pakcoy plants significantly. The aim of the study was to obtain a combination of organic materials that gave the best results on pakcoy plants. This field research was arranged based on the Randomized Block Design consisting of 4 treatments and 4 replications using a plot measuring 1 m², a spacing of 20 cm x 20 cm. The treatments were P0= catfish manure (control), P1= catfish manure + goat manure, P2= catfish manure + cow urine and P3= catfish manure + lamtoro leaves. The observed variables were the number of leaves, fresh weight harvested, root length and root weight. The results showed that catfish manure and goat manure (P1) significantly increasing the number of leaves, fresh harvest weight and root weight of pakcoy plants.

Abstract

This study aimed to determine the interaction effects of several maize varieties and KNO3 concentrations on maize production. The research was carried out from December 2020 to April 2021 at the Indonesian Cereal Research Institute Facility, Bajeng District, Gowa Regency, South Sulawesi (5°18'21.5"S, 119°28'38.6"E). The study was designed using a split-plot experimental design, where the main plot was variety (V) which consisted of 4 varieties V1 (NASA-29), V2 (JH-37), V3 (BISI-2), and V4 (Pioner P-35). The subplots were KNO3 (K) concentration which consisted of 4 concentrations, namely Control (K0), 2.5 g.L–1 (K1), 5 g.L–1 (K2), and 7.5 g.L–1 (K3). Observational data were processed using ANOVA, and if there was a significant difference in the treatment, it was further tested with a 0.05 LSD follow-up test. The results showed that the JH-37 variety gave the best response, such as plant height, cob length, and production. The 7.5 g.L–1 KNO3 concentration gave the highest effect on all parameters of maize production; The interaction between the JH-37 variety with 7.5 g.L–1 KNO3 concentration gave the highest maize production; Parameters that have a positive correlation with maize productivity are expressed by plant height and weight of 1000 seeds.

Abstract

Ubi Banggai biasanya diolah dengan cara direbus, digoreng, diparut dan dibuat nalum atau bubur khas Banggai kepulauan yang diolah dengan cara dimasak bersama santan kelapa dan garam. Penelitian ini bertujuan untuk mengetahui karakteristik, kandungan gizi, kandungan pati, dari tepung ubi Banggai terhadap lama dan macam perendaman. Jenis penelitian ini adalah penelitian eksperimen. Parameter yang diukur meliputi uji pati, yaitu tepung ubi Banggai yang dihasilkan diukur masing-masing kadar patinya. Uji proksimat yang dilakukan terhadap tepung ubi Banggai terdiri dari kadar karbohidrat, kadar protein, kadar lemak, kadar air, dan kadar abu. Analisis data penelitian dirancang dengan Rancangan Acak Lengkap (RAL) yang disusun secara faktorial dengan 2 faktor, (3 × 3) × 2 jenis ubi, maka ada 27 kombinasi perlakuan. Dalam penelitian ini faktor pertama menggunakan perbandingan lama perendaman dengan 3 taraf yaitu: L0 = 0 jam; L1 = 12 jam; L2 = 24 jam, sedangkan faktor kedua menggunakan beberapa bahan perendaman yang terdiri dari 3 taraf, yaitu: P1= Menggunakan Air; P2 = Menggunakan NaCl; P3= Menggunakan Na Bisulfit. Hasil penelitian menunjukkan bahwa seluruh kombinasi perlakukan memberikan pengaruh sangat nyata pada kadar pati, kadar abu, protein, lemak, dan karbohidrat, sedangkan kadar air memberikan pengaruh nyata.

Abstract

The present work aims to investigate the maturation-related changes in phenolic, and flavonoid profiles, also the antioxidant activity of Muntingia calabura at two maturity stages (young and old leaves). The leaves were extracted using water as the solvent. The total phenol and flavonoid content were determined, and the antioxidant capacity using a spectrometry assay to determine antioxidant compounds in Muntingia calabura leaves. The extract was analyzed with Fourier-transform infrared spectroscopy (FTIR) and Liquid chromatography-mass spectrometry (LC-MS). The extracts of old leaves demonstrated a higher total phenolic content (160.00 mg GAE.g extract–1) and total flavonoid content (82.55 mg Quercetin.g extract–1) also exhibited stronger scavenging activity against 2,2-diphenyl-1-picrylhydrazyl (DPPH) 75.03% compared to young leaves. Based on the FTIR measurement of the young and old cherry leaves, shows a similar pattern in both stages of leaf maturity. On the other hand, the LC-MS test revealed 12 active components of the extract of cherry leaves.
