Abstract

Industrial developments and increasing consumer concern for the environment and the issue of environmentally sound industrial concepts have forced the industry to adjust the concept of green industries in every business, including in procurement, which is better known as green procurement. Supplier selection is an important decision-making problem to get suppliers who can increase the company's competitiveness. This research was conducted in Jember regency to evaluate and select cassava suppliers based on green procurement using the AHP method. The criteria used are 6 criteria, namely quality, technology capability, pollution control, environment management, green product, and green competence. Each criterion has sub-criteria between 3 or 4 sub-criteria. The number of sub criteria is used to determine the RI value. The RI value is used to calculate the CR value of each criterion. The results of data processing show that the highest CR value is in the technology capability criteria and the lowest CR value is in environment management. The highest hierarchical criterion value for environmental management criteria is 0.273, because the selection of cassava suppliers can be expected to pay attention to environmentally sound controls.

Abstract

Porang (Amorphophallus muelleri B.) is a type of tuber that contains glucomannan, which is used as a raw materials for the food, chemical, pharmaceutical and cosmetic industries. In vitro culture as porang propagation method using plant parts (leaf explants) was developed under aseptic environmental conditions. Sterilization is an important aspect in the success of micropropagation in obtaining sterile explants. This research method used a Completely Randomized Design (CRD) with 2 factors, namely clothes bleach sterilant containing NaOCl 5.25% (Bayclin®) at 30% concentration for 15 minutes (Treatment A), and using clothes bleach containing NaOCl 5.25% (Bayclin®) at 30% concenteration for 15 minutes + 70% alcohol for 15 seconds (Treatment B). Each treatment was filled with 3 explants, and every treatment was repeated 27 times, so that experimental units were obtained with a total of 162 explants. Treatment B is the best treatment in obtaining sterile explants, because it is more effective in removing contamination and inhibiting contamination and browning with survival the highest rate of 51.85% and the lowest mortality rate of 48.15%, it can also suppress and inhibit the appearance of contamination and browning compared to treatment A.

Abstract

The coffee plant (Coffea sp.) is one of the plantation commodity crops that has been developed since the Dutch colonial era. The productivity of Arabica coffee from people's fields is equal to 0.48 tons/ha while the company's Arabica coffee plantations 0.71 tons/ha. Low productivity is one of them caused by fertilization that is not in accordance with the needs of coffee plants. So, it is necessary to know the nutrient content of N, P and K in each plantation. The content of N, P and K nutrients can be determined through the development of fertilization methods based on the loss of N, P and K nutrients carried by the harvested coffee cherries. The aim of this research is to find out of N, P and K nutrients are carried by Arabica coffee berries. The treatment was carried out at 5 different coffee fields locations and an analysis of the N, P, and K nutrient content of the harvested coffee cherries was carried out. The results showed that the nutrients N, P, and K carried by the coffee cherries were different in each plantation. Soil Analysis results on pH (bit acid) and Total Nutrient Content N (low), P (moderate – very high), and K  (low) in the soil of each field. The variables for observing the weight of sun-dried coffee beans and skins and the weight of oven-dried coffee beans and skins were significantly different in each plantation. Conclusions from this research, a). The total N, P, and K contained in 1 kg of fresh coffee fruit is 24.71 g N; 8.66 g P and 39.08 g K. b). The total N, P, and K contained in 1 kg of dry coffee beans is 74.3 g N; 26.1 g P and 117.5 ​​g K.

Abstract

The purpose of this study was to determine the response and yield of the stevia plant to different concentrations of old coconut water combined with two different types of irrigation, namely drip irrigation and sprinkler irrigation. The experimental design was a split plot with the RAK basic design pattern and two factors. The first factor is the use of different irrigation types, including drip and sprinkler irrigation. The second factor is the concentration of coconut water, which consists of 5 levels, namely A0 = 0% coconut water concentration, A1 = 25% coconut water concentration, A2 = 50% coconut water concentration, A3 = 75% coconut water concentration, and A4 = water concentration coconut 100%. Data analysis used the T-test to determine the effect of the type of irrigation and ANOVA to determine the impact of giving old coconut water with the F test at level α = 0.05. A DMRT test was done to measure the significant values of the ANOVA test. The results showed no interaction between different irrigation types and coconut water concentration for all observational variables. Different kinds of irrigation showed significant differences in some parameters. Giving old coconut water gives different results in each experiment.

Abstract

Utilization of vegetable waste can be used as organic fertilizer such as black water. Black water from vegetable waste is used as fertilizer to increase the growth and yield of water spinach. Black water can be made by using a decomposer in the form of lumbricus sp and EM4 worms to help with the decomposition process. The planting medium of filter cake compost is an additive for soil amendments that support the availability of nutrients in plants. This study used the addition of decomposers EM4, rumen MOL, and Trichoderma sp. This research used a two-factor factorial with a completely randomized basic design (CRD) consisting of 2 factors and three replications. The interaction between the application of the black water decomposer and the filter cake media did not have a significant effect on all the observed variables. Likewise, with the single factor, the application of black water does not have a significant effect on all observed variables. The single factor in the treatment of using filter cake media has a substantial impact on all observational variables. The best treatment was on M3, comparing the composition using 20% filter cake planting media and 80% soil.

Abstract

Land use changes that occur due to population pressure and land conversion that are not in accordance with the RTRW will affect the sustainability of the development of an area. In the period 2003 to 2013, it is known that land changes occurred in Kolaka sub-district, namely that the production forest experienced a reduction in area of ​​266.26 Ha of the total land area, which was converted into dry land. Some possibilities include land conversion from forest area to plantation land by residents. Meanwhile, in the period 2013 to 2023, Production Forests became land with a very large degraded area, where an area of ​​1884.48 ha was converted into wetlands, dry lands, and as limited production forests. The condition of this land use change was then analyzed for its suitability to the 2012 - 2023 RTRW of Kolaka Regency. It was found that 75.53% or an area of ​​10,579.55 ha of the existing area was still suitable, while the unsuitable area was 24.47% or an area of ​​3426.91 ha.
