Inulinase (EC 3.2.1.80) is an enzyme that can hydrolyze inulin into fructose or fructo-oligosaccharides. Using the inulinase enzyme as a catalyst in making inulinase-based fructose can obtain a fructose percentage of 90-95 percent. Inulin is a linear polysaccharide (ß-2,1-linked d-fructose residue terminated by a glucose residue) that accumulates as a storage carbohydrate in plants. One natural source that can produce inulin is bananas. Bananas are a source of inulin which contains around 0.58-1.09 percent. This research used three types of bananas, including Musa X paradisiaca, Musa paradisiaca formatypica, Musa paradisiaca var sapientum. Apart from that, you can also find out the characteristics of the microbes and enzyme activity produced from the three types of bananas. The results of this research show that the three isolated types of banana are capable of producing the inulin ase enzyme which is indicated by the growth of these microbes in ISM media. ISM media (Inulinase Selective Media) is an inulinase mixing media where only inulin-producing microbes can grow on the media. The microbes isolated from the three types of bananas that had the highest inulinase enzyme activity value were Raja Nangka bananas with an enzyme activity value of 0.405 IU/mL. Meanwhile, the lowest inulinase enzyme activity value was in Kepok bananas with an enzyme activity value of 0.088 IU/mL.
菊粉酶（EC 3.2.1.80）是一种能将菊粉水解成果糖或果寡糖的酶。使用菊粉酶作为催化剂来制造菊粉基果糖，可以获得 90-95% 的果糖比例。菊粉是一种线性多糖（ß-2,1-连接的 d-果糖残基以葡萄糖残基终止），在植物中作为储存碳水化合物积累。香蕉是产生菊粉的天然来源之一。香蕉是菊粉的一种来源，其含量约为 0.58-1.09%。这项研究使用了三种香蕉，包括 Musa X paradisiaca、Musa paradisiaca formatypica 和 Musa paradisiaca var sapientum。除此以外，还可以了解这三种香蕉所产生的微生物和酶活性的特点。研究结果表明，这三种分离出来的香蕉都能产生菊粉糖酶，这从这些微生物在 ISM 培养基中的生长情况可以看出。ISM 培养基（菊粉酶选择性培养基）是一种菊粉酶混合培养基，只有产菊粉的微生物才能在培养基上生长。从三种香蕉中分离出的微生物中，菊粉酶酶活值最高的是 Raja Nangka 香蕉，酶活值为 0.405 IU/mL。而菊糖酶酶活值最低的是 Kepok 香蕉，酶活值为 0.088 IU/mL。

Rice plants is the main food crop in Indonesia. Gresik is one of the ten highest rice producing regions in East Java Province, Indonesia. Rice production in Babaksari Village, Gresik Regency reaches 646 tonnes/year. One of the obstacles in rice production is bacterial leaf blight caused by Xanthomonas oryzae pv. oryzae. This disease can cause yield loss reaching 15-80%. The development of bacterial leaf blight in rice can be caused by several factors, one of which is abiotic factors. This study aims to determine how far the influence exerted by abiotic factors (air humidity, soil pH, and air temperature) on the intensity of bacterial leaf blight. The research was conducted using a survey method, diagonal random sampling, and interviews with farmers in Petissari Hamlet and Sariwonorejo Hamlet, Babaksari Village, Dukun District, Gresik Regency. From the results of this study it was found that the three abiotic factors simultaneously had a significant effect on the intensity of bacterial leaf blight with the regression model obtained, namely: (1) Petissari: Y = -0.050 + 0.587X1 +1.378X2 – 0.789X3; and (2) Sariwonorejo: Y = 8.464 - 3.044X1 +3.745X2 + 1.854X3. The results of path analysis showed that the abiotic factor that had the highest direct effect on the intensity of bacterial leaf blight was soil pH.

The market demand for potatoes is very high, and their cultivation can affect the environmental balance, so innovation in potato yield is needed. Medium land is an area with an elevation of 300-700mdpl. Crop yields in medium land are not optimal and more susceptible to disease than highlands. The role of microorganisms in PGPR and Tricho Powder can maximize crop yields and help reduce disease intensity. This study aims to determine the effect of different concentrations of commercial PGPR in increasing the yield of potato cultivation, the effect of different concentrations of Tricho Powder in suppressing the intensity of disease attacks, and find out one species in PGPR. This research was conducted with RAL (6 treatments with 4 replications). The treatments included P0 (Farmers’ Habits), P1 (PGPR 20mL), P2 (PGPR 40 mL), P3 (Tricho Powder 80gram/10Liter), P4 (Tricho Powder 150gram/10L), and P5 (PGPR 20mL+Tricho Powder) 80gr/10L). The data was then analyzed by ANOVA. If there is significance, a follow-up test is carried out, which is determined based on the KK value. The results showed that differences in PGPR concentrations positively affected potato yields with the combination treatment of PGPR 20mL/10L+Tricho Powder 80 gr/10L (P5), which was the best treatment producing the highest mean in each parameter. In the same treatment, disease intensity was reduced by 37.55% compared to the control treatment. Based on its ability to produce IAA from 5 isolates, only 1 isolate (IS 5) showed positive results and was continued to molecular tests.

Ice cream cones are a type of wafer with a cone or funnel-like shape used as a container that holds ice cream and baked in an ice cream cone maker with the basic ingredient of wheat flour, which can be added with other ingredients for innovation. A factorial completely randomized design (CRD) was employed with two factors: the ratio of wheat flour to tofu dregs flour (90:10, 80:20, 70:30) and the percentage of beetroot extract in 100 ml of water (30, 40, 50%). This study aimed to determine which ice cream cone formulation(s) from wheat flour, tofu dregs flour, and beetroot (Beta vulgaris L.) extract had the highest protein and betacyanin content and was most favored by consumers. Results showed that formulation with the 70:30 flour ratio and 30% beetroot extract produced the highest protein content of 13.55%, and the 90:10 flour ratio and 50% beetroot extract created cones with the highest betacyanin content of 0.074 mg/100g. The product preference test based on organoleptic properties revealed that the panelists mostly preferred cones made with the 80:20 flour ratio and 30% beetroot extract because of the resulting color (3.53, like slightly), taste (3.61, like slightly), aroma (3.78, like slightly), and crispness (4.32, like), with an overall preference of 4.07 (like).

The development of grapes (Vitis vinifera) has obstacle among others are limited optimal land and difficult nurseries. Suboptimal land use for grape cuttings can use red yellow podzolic soil (ultisol). Podzolic soil has an acidic pH and low macro and micro nutrient uptake but can still be used as a growing medium. Vierul local grapes are a type of grape that has begun to be developed as root stock in nurseries but needs to be improved for its root success using a synthetic phytohormones bath of napthaline acetic acid (NAA). The purpose of this study was to determine the morphological character of vierul local grape cuttings at various concentrations of NAAsoaking in podzolic soil growing medium. This research has been carried out in a screen house from August to December 2021. This study used a non-factorial completely randomized design (CRD) with 3 treatments and 3 replications as block consisting of F0, F1, F2, F4 following by 0, 2, 4, 6 g L-1 respectively. The morphological characteristics observed is number of bud break, time of leaves appear, number of leaves, tendril length and percentage of live cuttings. The results of the study were analyzed using ANOVA at the 5% level and continued using the DMRT at the 5% level. The result showed that soaking of NAA at a concentration of 0 g L-1 (F0) had the best result for the variable number of bud break and number of leaves. Concentration of 6 g L-1 (F3) had the best result for variable length of the tendril while for the variable when the leaves appear, NAA soaking has no significant effect. The percentage of live cuttings is still low because it is influenced by the quality (material) of cuttings, the age of woodstock, growing media and water availability.

Cassava farming in Salatiga City is a food-crop commodity farming business that has good opportunities because the demand for cassava in the market is increasing. However, some obstacles hinder cassava farming, namely cassava productivity which has not reached the target and limited production factors. This indicates that the use of production factors is still not efficient. Production factors that directly affect the productivity of cassava are land area, seeds, fertilizers, and labor. The aims of this study were: (1) to analyze the influence of production factors on cassava production, (2) to analyze the level of elasticity of cassava production factors, and (3) to analyze the level of technical efficiency and economic efficiency in cassava farming activities in Salatiga City. The analytical method used is the Cobb-Douglas production function with thehelp of the SPSS program to examine the influence of factors on cassava production and production elasticity. Technical efficiency is analyzed using the stochastic frontier production function. The results showed that the factors of seeds, manure, and labor were thought to affect cassava farming. The results of the elasticity analysis of all factors of production are in the rational area (Region II) with a positive value. The results of the technical efficiency analysis show that only the seed variable has a positive and significant value. Based on the results of the calculation of economic efficiency analysis, it shows that the input use of the land area, seeds, manure, and labor is not efficient.

Chromium is a heavy metal that is toxic, bioaccumulative, persistent, and cannot be decomposed in the environment. The Cr6+ ion is a chromium ion that has the highest toxicity among other chromium ions, so its presence in the environment is hazardous for plants, animals, and humans. Sulfur is an essential element for plants, whose presence can reduce Cr6+ concentrations in the terrestrial environment by inhibiting the uptake of Cr6+ by plants. Tagetes erecta is a bioremediation agent plant that can remediate land polluted with Cr6+ waste. In this research, we studied the growth of T. erecta in media polluted with Cr6+ and sulfate and its ability to accumulate of Cr6+. Several parameters observe in this experiment, i.e. growth parameters, namely plant height, number of leaves, number of flowers measured at the end of the study, dry weight, root length, and Cr6+ concentration estimated using the diphenylcarbasid method. The results showed that the plant height of T. erecta. was not significantly different, and sulfate addition did not affect plant height. The addition of sulfate affected the number of leaves and flowers, dry weight of root shoots, root length, and Cr6+ content in T. erecta. polluted with Cr6+. so that in these parameters, there was a significant difference in the addition of Cr6+ and sulfate on growth of T. erecta and its ability to Cr accumulation.

Chili is used not only as a vegetable for consumption or a complement to dishes but also as an attractive ornamental plant to cultivate. One of the genetic enhancement efforts is through mutation induction with gamma rays. The aim of this study was to increase the genetic diversity of ornamental chilies by inducing gamma ray mutations. This research was conducted at BATAN (National Nuclear Energy Agency), experimental field and Plant Breeding and Biotechnology Laboratory, Faculty of Agriculture, Jenderal Soedirman University. The research was conducted from July to November 2022. The results showed that the LD50 value of gamma-ray irradiated chili seeds was 213.49 Gy, and there was an increase in the diversity of ornamental chili mutants. The color characteristic of mature leaves was purplish-green in the control plant, while the mutant turned purple on the upper and lower surfaces of the leaves. The character of the flower has not changed; that is, it remains purple, and the flower stalk remains upright. The stem pigment in control plants was a purple-green line, changed to purple in mutants. Mutant plant habitus changed to compact. These characters increase the aesthetic value of the ornamental chili mutant.
