Abstract

Coffee is one of the commodities in Indonesia that excels in exports, and one of the most widely cultivated coffees in Indonesia is robusta coffee. Propagation by segment cuttings on Robusta coffee plants can produce new plants in large numbers and have the same gene characteristics as the parent in a short period. Then there is a growth regulatory administered exogenously (from outside) are an alternative way to accelerate root formation in plants. This study was conducted to determine the effect of the number of segments and concentration of Rootone-F on the growth of robusta coffee cuttings. The research was conducted for three months, from 23 March 2021 to 15 June 2021. The research was conducted at the Kaliwining Gardens, the Coffee and Cocoa Research Center, Jember. The statistical method used was a completely randomized design (CRD) by factorial. The first factor was the number of segments and the second factor was the concentration of Rootone-F; there were 12 treatment combinations and three replications. The results showed that the number of internodes' treatments was significantly different on shoot length, root wet weight, and root dry weight. The concentration of Rootone F was not significantly different for all variables observed.

Abstract

Cocoa is one of the commodities as a foreign exchange earner in addition to oil and gas. However, Indonesian cocoa imports have increased from year to year due to low cocoa productivity. Whereas in terms of region, Indonesia has the potential to become a new cocoa power country in the world of cocoa production. This study examines the effect of rainfall, the number of rainy days, and air temperature on cocoa production in the Gunungkidul district. This study uses a quantitative descriptive method. The data used in this study is secondary data in the form of time series data on rainfall, rainy days, air temperature, and cocoa production in 2016-2020 in Gunungkidul Regency. The regression analysis results showed that all observed climatic factors such as rainfall, rainy days, and temperature did not have a significant effect on cocoa production in Gunungkidul Regency. However, the time-series data shows that the highest cocoa production was in October 2017 and November 2018 to January 2019, when rainfall and intensity (rainy days) began to increase. Meanwhile, the air temperature in Gunungkidul Regency for five years is around 24-26°C, which is the optimum temperature for cocoa growth. This study concludes that rainfall, rain intensity (rainy days), and temperature affect fluctuations in cocoa production.

Abstract

Sugarcane (Saccharum officinarum L.) is a plantation crop that is used as raw material for the consumer sugar and industrial sugar. The need for sugar is increasing every year but is not matched by an increase in sugarcane production due to several factors including cultivation management that is not optimal. Sugarcane production begins with good nursery management, including using genetic of seeds and the right planting media. One alternative to improve the quality of growing media is to use humic acid (HA) as a soil enhancer. This study aims to determinate the effect of giving HA on the morphological characteristics of sugarcane seedlings of Bululawang variety (BL). This research was carried out in an integrated laboratory greenhouse at the Polytechnic LPP Yogyakarta from Maret to July 2021. This study used a non-factorial completely randomized design (CRD) with five treatments and three replications consisting of P0 (control), P1 (25 ml.polybag-1), P2 (50 ml.polybag-1), P3 (75 ml.polybag-1), and P4 (100 ml.polybag-1). The morphological characteristics observed is plants height (cm), number of leaves (strands), stem diameter (mm) and longest root length (cm). the results of the study were analyzed using ANOVA at the 5% level and continued using the Duncan Multiple Range Test (DMRT) at the 5% level. The result showed the effect on morphological characters on all observation variables where the P3 treatment had the best growth and morphological characters, so that in general the additional of HA affected the morphological characteristics of sugarcane seedlings of BL varieties.

Abstract

Fruit-sucking bugs (Helopeltis spp.) are one of the main pests on cocoa plants. The damage caused by this pest is by piercing and sucking the liquid of cocoa pods and young shoots. This study aimed to obtain the effective concentration of papaya leaf extract and yam extract on the mortality of cocoa fruit-sucking bugs. This research was carried out at the Plant Production Laboratory II of the Politeknik Negeri Lampung from September 2020 to January 2021. The design used in this study was a Randomized Block Design consisting of 4 treatments and six replications. The results showed that the average daily mortality rate fluctuated in each treatment. In all treatment concentrations of papaya leaf extract and yam extract, the average mortality of cocoa fruit-sucking bugs ranged from 25.76% to 75.76%. All treatment concentrations of papaya leaf extract and yam extract were not effective in the mortality of cocoa fruit-sucking bugs.

Abstract

Fermentation of cocoa beans can produce flavour precursors and colour changes in chocolate. Generally, this process is carried out for 5-7 days without adding starter culture. Adding a starter culture is considered to improve the quality of cocoa beans and shorten the fermentation time. The purpose of this study was to compare the starter cultures used in the cocoa bean fermentation process through a meta-analysis approach. Twenty-four related articles have been screened from the initial number of 110 articles. There are five starter cultures and six parameters that can be processed by Confidence Interval (CI) analysis. Calculating p and I2 values ​​using STATA software was performed to see variations between studies and test the significance of their effects during the fermentation process through p values. The variation test between studies showed that the profiles of lactic acid bacteria (LAB) and acetic acid bacteria (AAB) were heterogeneous. While the yeast profile, levels of lactic acid, acetic acid and pH between studies are homogeneous. The results of the study showed that the addition of starter culture will affect the levels of yeast profile (ES: 0.470; 95% CI: 0.371 to 0.569; p = 0.0); LAB profile (ES: 0.747; 95% CI: 0.600 to 0.894; p = 0,0); AAB profile (ES: 0.808; 95% CI: 0.663 to 0.953; p = 0.0); lactic acid (ES: -0.003; 95% CI: -0.162 to 0.156; p = 0.039); acetic acid (ES: 0.189; 95% CI: 0.01 to 0.368; p = 0.039) and pH (ES: 0.109; 95% CI: 0.001 to 0.218; p = 0.049). Using pure starter cultures can increase the number of microbes of the type added and increase metabolic activity by showing a decrease in acetic acid levels in cocoa beans at the end of the fermentation process. However, no changes were seen in pH or lactic acid levels.

Abstract

Propagation of vanilla plants is generally using vegetative methods like cuttings. The use of external growth regulators can support the growth of nurseries. Phosphate solubilising bacteria and potassium solubilising bacteria as plant growth promoting rhizobacteria are producing microbial IAA. This study used auxin in synthetic IAA combined with IAA microbes from phosphate solubilising bacteria and potassium solubilising bacteria. This study aimed to determine the effectiveness of each microbe at each dose of synthetic IAA that was applied. The study was conducted from November 2021-April 2022 in the Biological Soil Laboratory and Greenhouse University of Jember. The research uses a randomised block design with three replications with the factorial arrangement. The first factor was organic matter which was enriched with bacterial isolate (B0 = control, B1 = BPF isolate, and B2 = BPK isolate). The second factor was concentration of IAA (A0 = 0 mg.l-1, A1 = 100 mg.l-1, and A2 = 200 mg.l-1). The data were analysed by ANOVA and further tested with Duncan Multiple Range Test (DMRT) with a 95% confidence level. The results showed that treatment of synthetic IAA affects the parameters of length and volume of adventitious roots, which are effective in helping to supply nutrients with the best treatment at a concentration of 200 ppm. Meanwhile, enrichment of media with isolates of phosphate solubilising bacteria and potassium solubilising bacteria gave a better effect than control on the observation of tendril length, number of leaves, number of adventitious roots and taproots, length of adventitious roots and taproots, the volume of adventitious roots and taproot, and fresh weight of vanilla seedlings.

Abstract

Cocoa pod sucking (Helopeltis spp.) is one of the pests that causes a productivity decrease of cocoa pod in Indonesia. In terms of control, many farmers in Indonesia are still using synthetic insecticides that are not environmentally friendly, so intoxicating yam (Dioscorea hispida Dennts) and tropical whiteweed (Ageratum conyzoides L.) are used as botanical insecticide that are environmentally friendly. The objective of this research is to determine the effect of botanical insecticide that made of intoxicating yam extract, tropical whiteweed extract, and mixed extract of intoxicating yam and tropical whiteweed on the mortality of cocoa pod sucking pests. This research was carried out from November 2020 to February 2021, at the Plant Laboratory II Estate Crop Department, Politeknik Negeri Lampung. The research used a Randomized Block Design (RBD) consisting of four treatments, namely: P0 (control), P1 (intoxicating yam extract), P2 (tropical whiteweed extract), and P3 (combination of both extracts), which were repeated six times. The highest mortality of cocoa pod sucking pests was found in treatment P1 (72.73%). The mortality of cocoa pod sucking pest was caused by extract of intoxicating yam which contains the active ingredients of saponins, alkaloids, flavonoids, and cyanide which enter the digestive system of the cocoa pod sucking pest as stomach poisons, resulting in the death of the cocoa pod sucking pest. Based on the results of the research, it was concluded that intoxicating yam extract is the most potential as botanical insectiside for cocoa pod sucking pest.
