Abstract

Arabica coffee cultivation is limited by altitude, which affects its production. Some farmers in Jember Regency are innovating to grow arabica coffee in the lowland, but the potential for leaf rust disease is quite high. Plant natural resistance can be enhanced by adding minerals formulation (containing silica, iodine, and calcium). This research aimed to determine which phase is more effective for applying mineral formulation that induces plant resistance. The formulation was tested on arabica coffee plants grown at the lowland (460 masl) in Jember Regency on 12 years old (y.o) mature and 1 y.o immature plants. One formulation was dissolved in 14 L of water and applied by foliar feeding. The effect was analyzed using two-way T-test of two samples assuming unequal variances at 95% confidence level to determine the differences. The analysis showed that the plants supplemented with the formulation could increase the variables that supported the natural resistance of plants (both mechanically and through the production of chemical compounds), such as polyphenol content, flavonoids, antioxidant activity, total dissolved protein, vitamin C, reducing sugar, lignin, cellulose, hemicellulose, and iodine content in the plant. The response of the formulation application showed that the most resistance variables was better in 1 y.o immature plants than in 12 y.o mature plants. The application of mineral formulation in immature phase will have a better impact on increasing natural resistance, and it has the potential to be used as a supplement for arabica coffee plants cultivated in the lowland.

Abstract

The identity of coffee is significant for consumers mostly in relation to the characteristics of the end result product taste and quality. Robusta coffee varieties are widely grown by farmers in Bondowoso Regency in east Java, Indonesia using planting materials of unknown origin. The objective of this work was to identify the physical and chemical occurrence of Robusta cherries harvested from seven chosen genotypes grown in Curahpoh Village, Bondowoso. Samples of Robusta coffee cherries of seven selected genotype plants were harvested from Curahpoh Village, Bondowoso at three levels of maturity. Some physical and chemical factors were assessed as follows: sphericity, bean density, weight per bean, moisture content, total dissolved solids, to elicit differences in the genotypes. Analyzing the results obtained, the authors pointed to rather serious differences in these characteristics between various genotypes. The sphericity of fresh coffee fruits ranged from 0.82 to 0.93, with average density values between 1.00 and 1.11 g/cm³. The moisture content of green beans varied widely from 4.46% to 22.79%, while total dissolved solids ranged from 2.67% to 5.27%. These studies suggest the possibilities of genotypes selection in order to produce a superior genotype that would improve the quality as well as the marketability of Bondowoso Robusta coffee. These data contribute to the enhancement of the current agricultural practices, and the proposal of new varieties of coffee adapted to the specifics of their environment.

Abstract

A major limiting factor for rice production in the tropics is the decline in seed quality due to storage duration and environmental conditions. Rice seeds are often stored for extended periods, making seed expiration unavoidable. Expired seeds frequently undergo quality deterioration. Therefore, an effective approach is needed to mitigate quality decline and sustain rice production. This study aims to evaluate the effectiveness of different matriconditioning techniques and various concentrations of onion peel waste-derived plant growth regulators (PGRs) in maintaining seed viability and rice yield. The research was conducted using a Completely Randomized Design (CDR) with a two-factor experimental setup and three replicates. The first factor was the matriconditioning medium, consisting of three levels: M1 (soil), M2 (soil + husk charcoal), and M3 (soil + husk ash). The second factor was the concentration of onion peel waste-derived PGR, consisting of four levels: K1 (0% – water), K2 (25% – 250 mL onion peel waste PGR per 1000 mL), K3 (50% – 500 mL onion peel waste PGR per 1000 mL), and K4 (75% – 750 ml onion peel waste PGR per 1000 mL). The results showed that matriconditioning with soil and husk charcoal, along with 25% onion peel waste-derived PGR, enhanced rice seed viability. Additionally, a 75% concentration of onion peel waste PGR significantly influenced the weight of 1000 grains and the total harvested grain weight.

Abstract

The need of sugar cane for sugar production continues to increase yearly as human population increasing. Based on Central Bureau of Statistics, sugar cane production in Indonesia grew by 3.54% per year. However, this growth is not sufficient to meet the sugar demand of 2.70 million tons. The cause of Indonesia's low sugar production can be seen from the on-farm side, namely seed preparation. Preparing seeds using conventional methods (mules) affects the seeding time because it takes 6 months for one planting period. The experimental design was carried out using the basic pattern of a Completely Randomized Factorial Design consisting of two factors with three replications. Factor I, namely the dose of NPK inorganic fertilizer (16:16:16) and Factor II, namely the dose of Sinarbio biological fertilizer. The results of the research were (1) The interaction between the treatment of NPK fertilizer doses and biofertilizer doses on the growth of sugarcane bud chip seedlings had a significant effect on shoot length and an insignificant effect on the variables number of leaves, stem diameter, number of tillers, root volume, root wet weight and root dry weight. (2) The effect of NPK fertilizer dosage on the growth of sugarcane bud chip seedlings had no significant effect on all observed variables except root wet weight and number of tillers. (3) The effect of biofertilizer dosage on the growth of sugarcane bud chip seedlings had no significant effect on all observed variables except root volume.

Abstract

Oyster mushroom (Pleurotus ostreatus) is a popular mushroom in Indonesia, with several factors affecting its yield, including seed quality, cultivation methods, and environmental conditions. The choice of planting media is crucial, as it must provide essential nutrients. Common media include straw and coffee husks, with the addition of liquid organic fertilizer (LOF) enhancing productivity. Maja fruit is particularly beneficial due to its NPK content, supporting mushroom growth. This research, conducted from February to May 2024 in Klungkung Village, Jember Regency, employed a completely randomized design (CRD) with three replications. The study tested media compositions—100% sawdust (M1), 75% sawdust and 25% straw (M2), and 75% sawdust and 25% coffee husk (M3)—alongside varying LOF concentrations: no LOF (P0), 75 ml/liter (P1), 150 ml/liter (P2), and 225 ml/liter (P3). Results indicated that the interaction between LOF concentration and media composition significantly affected the total number and weight of fruiting bodies. The best combination was P1M2 (75 ml LOF/liter with 75% sawdust + 25% straw). Media composition significantly influenced the number and weight of fruiting bodies, with M3 (75% sawdust + 25% coffee skin) recommended as the optimal choice. LOF concentration notably impacted total fruit body weight, while other parameters showed no significant differences.

Abstract

One problem of peanut cultivation is the inability of peanut seeds to be stored long-term. Prolonged storage of seed peanuts causes seed deterioration due to seeds losing reserves of food and nutrient that cause the seeds difficult to germinate. As well as other problems, namely Nitrogen, Phosphorus and Potassium fertilization which has not been based on plant needs, fertilizer application tends to be excessive. The purpose of this study is to know the interaction and the main effect of the concentration treatment of coconut water immersion and NPK fertilization doses. This study used a factorial randomized block design with three replications. The first factor was the immersion concentration of coconut water (A) which consisted of 3 levels, namely: 0% coconut water (A1), 15% coconut water (A2), and 30% coconut water (A3) and the second factor was the dose of NPK fertilization (B) consisting of 4 levels, namely: NPK 0 g/plot (B1), NPK 22.5 g/plot (150 kg/ha) (B2), 45 g/plot (300 kg/ha) (B3), and NPK 67.5 g/plot (450 kg/ha) (B4). The results showed that (1) there was a significant interaction only on the number of primary branches with the applied treatment, 15% coconut water immersion concentration and NPK fertilization dose of 22.5 grams/plot (A2B2) (7.7 branches). (2) Concentration immersion in coconut water significantly affected the percentage of pithy pods, the percentage of empty pods, and the weight of 100 seeds, with the best treatment being the concentration of 15% coconut water immersion (A2). (3) Dose of NPK fertilization factor had a significant effect on harvesting age, percentage of empty pods, wet pod weight and productivity with the best treatment of 67.5 gram/plot NPK fertilization (B4).

Abstract

Kombucha is a fermented beverage product often produced by adding kombucha culture into sweetened tea, juices, coffee, and herb extracts. Coffee is a refreshing ingredient commonly served as a beverage prepared from roasted coffee beans. Therefore, this study aimed to investigate the chemical and microbiological characteristics of kombucha beverage produced from robusta and arabica coffee through natural methods with light, medium, and dark roasting profiles. Ground-roasted robusta and arabica coffee were dissolved into a sucrose solution, then the kombucha culture was added to these treatments and fermented for 14 days at ambient temperature. Subsequently, each kombucha beverage was analyzed for Total Soluble Solid (TSS), pH, Total Titrated Acid (TTA), Soluble Vitamin C, Caffeine Content, and Total Lactic Acid Bacteria (LAB). The results showed that TSS decreased on the 14th day due to sucrose degradation by microbes. TTA increased at the end of the processing, followed by a lower pH (2.87–3.49), signifying a safe value for human consumption. The soluble Vitamin C increased on the seventh day and decreased on the 14th day, which was related to the oxidation process during fermentation. The monoanion of ascorbic acid became oxidized by oxygen molecules and formed other unstable compounds. The total LAB and caffeine content elevated along with fermentation time due to the caffeine solubility which increased in low pH solution.

Abstract

Coffee as one of the plantation commodities has an important role in the growth of the Indonesian economy. One of the areas producing Robusta and Arabica coffee located at the foot of Mount Argopuro, Curahdami District, Bondowoso Regency, East Java Province is Curahpoh Village. Farmers of Curahpoh Village who are members of the LMDH Argo Santoso Farmer Group actively cultivate coffee, especially Robusta coffee, as a source of livelihood for the community. The Robusta coffee processing process will produce waste in the form of coffee skins which can cause unpleasant odors and pollute the environment. The community service activities of this Fostered Village began with the Argo Santoso Forest Village Community Institution (LMDH) farmer group, Curahpoh Village, Bondowoso Regency, East Java Province. This program aims to train the Curahpoh Village community to process coffee skin waste into organic fertilizer. This community service activity was attended by 20 people. This program was implemented through the stages of socialization, practice and evaluation. The results of the program showed that participants were able to master the technique of processing organic fertilizer from coffee skin waste well.
