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.

Certification is the judgment of a third party as a liaison between the buyer and the seller, where both parties must meet all of their respective certification criteria or standards.

This study aims to determine the difference between the selling price of Rainforest Alliance and Fairtrade-certified coffee at the Rahmat Kinara multi-purpose cooperative, Pegasing, Central Aceh. This research uses time-series data, analyzed using the Mann-Whittney Test (U Test). The results of the Mann-Whittney Test (U Test) showed a significant value of (0.000) < ? 0.05, meaning that there is a significant difference between the selling price of Rainforest Alliance and Fairtrade-certified coffee. Sustainable Agriculture Support at the Rahmat Kinara multi-purpose cooperative improved the quality of the coffee crop (ecologically), helped withstand volatile price changes in global markets (economically), assisted in improving farm management, negotiating leverage, and providing access to premium markets (socially fair).Certification, Rainforest Alliance, Arabica Coffee, Fairtrade

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.

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.

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).

Weed interference results in increased synthesis of reactive oxygen species (ROS). High accumulation of ROS causes oxidative stress and stimulates the activation of the antioxidant defense system in plants. Weed interference causes biotic stress in the form of allelochemicals and abiotic stress in the form of competition for plants which results in the inhibition of growth and development in plants. Ageratum conyzoides is an annual weed in plantations and can cause biotic and abiotic stress on surrounding plants. This study aims to determine the effect of A. conyzoides interference on antioxidant content in the form of total phenol and total proline in patchouli leaves [Pogostemon cablin (Blanco) Benth cv. Sidikalang] as well as the percentage of essential oil yield from P. cablin. The study was conducted with a Complete Randomized Design (CRD) with a single factor of A. conyzoides interference levels in as many as four treatments (0, 2, 4, 6 individuals of A. conyzoides per treatment). The results concluded that higher levels of A. conyzoides interference led to an increase in total phenol and total proline in P. cablin leaves, but decreased the percentage yield of P. cablin essential oil.
