Abstract

Melon are plants that are sensitive to environmental changes. Currently, developing technology for cultivating melons in greenhouses is used to modify the microclimate for the growth of melon plants. This research aims to determine the effect of microclimate and different types of planting media on growth response of sweet net variety melon plants that planted in the Politeknik Negeri Jember smart green house. The research was carried out in January – May 2024. The treatments tested consisted of two treatments, namely: the use of soil media+compos and cocopeat media which would be repeated 15 times. The parameters observed include microclimate (temperature and humidity) and also plant growth indicators including plant length and number of leaves, number of flowers, and potential weight of melon. The data obtained were analyzed using the T-test. The research results show that the microclimate inside the Politeknik Negeri Jember smart green house is still classified as an optimal microclimate to support the growth of melon plants. Apart from that, the use of cocopeat planting media was able to provide the best results for the length of the melon plants in the 4th to 6th week of observation, but there was no significant difference in the parameters of the number of leaves, number of flowers and potential weight of melon of. The use of cocopeat media and soil media are both good media in supporting the growth of melon plants in a greenhouse.

Abstract

Drought is the global challenge of crop agriculture across the globe. The detrimental effect of drought hinders a significant growth and development impairment leading to devastating harvest losses. Maize, a vital staple for food faces future challenges with a rapidly expanding drought area. To address this challenge, scientists and breeders are urged to develop new varieties that are not only resistant or tolerant but also even potentially thrive under drought planting conditions. New breeding technologies involving molecular biology and biotechnology have been developed and implemented thus offering a promising solution. Genetic engineering has allowed humans to straightforwardly transfer beneficial genes across species and varieties, thus deliberating gene pool transfer of similar species and varieties. Furthermore, this technology has evolved to the level of creation, deletion, or modification of existing alleles with high precision through CRISPR/Cas9-mediated genome editing. This review article delves into the morpho-physiology, biochemical, and molecular responses of maize varieties against drought stress. It subsequently explores how genetic engineering has been utilized to optimize the selected genes underlying those responses. By exploring the current progress of genetic engineering, this article aims to prepare the ground for future advancement in combating drought through drought-tolerant maize varieties. Thus, this review article has the potential to contribute to improving food security in the increasing drought challenges.

Abstract

This study aims to determine the caffeine content of Argopuro Jember robusta coffee beans based on differences in post-harvest processing methods. The research was conducted at the Jember State Polytechnic Agricultural Products Processing (PHP) Laboratory and the Jember State University Integrated Testing Unit Laboratory in June-September 2022. The samples were robusta coffee logs originating from the Argopuro area of ​​Jember. The post-harvest coffee processing process is divided into four (4) methods, namely natural processing (dry process), semi-wet processing, wet (full wash process), and honey processing. Green beans from the results of each processing method are roasted at light, medium, and dark levels. The roasted bean caffeine content test from each post-harvest processing method at each roasting level was carried out descriptively (simple, without repetition). Overall, the caffeine content of the roasted beans produced in this study still meets the SNI 01-3542-2004 standard, a maximum of 2%. The caffeine content of Argopuro Jember robusta coffee roast beans at the light roast level ranges from 1.44-1.65%, 1.38-1.92% for medium roast, and 1.61-1.81% for dark roast. The highest caffeine content in roasted beans at each roasting level is 1.65% (dry process), 1.92% (full wash process), and 1.81% (full wash process), respectively. Meanwhile, roasted beans with the lowest caffeine content with a value of 1.38% are produced using the semi-wet process processing method at a medium roast level. The fluctuations in caffeine values ​​produced in this study indicate that post-harvest processing methods do not affect the caffeine content of roasted beans at light, medium, or dark roast levels.

Abstract

The moth orchid (Phalaenopsis amabilis) is a popular ornamental plant due to its beautiful flowers. Propagation of moth orchids can be performed using tissue culture or in vitro methods. The medium used in moth orchid tissue culture is the MS (Murashige and Skoog) medium, which is enriched with plant growth regulators (PGRs). The use of natural PGRs, such as onion extract and coconut water, can serve as an alternative and potential source nutrition substitute for synthetic PGRs in orchid tissue culture media. This study aims to determine the effect of using natural PGRs, namely onion extract and coconut water, on moth orchid plantlets. The method employed is a Complete Randomized Design (CRD) factorial experiment with two factors: the first factor is the concentration of onion extract (0 g/L, 20 g/L, 30 g/L, and 40 g/L), and the second factor is the concentration of coconut water (0 mL/L, 50 mL/L, 100 mL/L, and 150 mL/L). Observations were focused on the increase in the number of roots and leaves. The results showed that a concentration of 20 g/L onion extract had a significant effect on the increase in the number of roots but did not affect the increase in the number of leaves. Meanwhile, the concentration of coconut water did not affect the increase in the number of roots or leaves.

Abstract

The use of organic and inorganic fertilizers is an alternative way to get good cabbage production, one of which is by using cow manure and NPK. This study aims to determine the good use of a combination of cow manure and NPK fertilizer on the growth and yield of cabbage (Brassica oleraceae L.). The research was carried out from October 2022 to January 2023. This study used a Randomized Block Design (RAK), namely with a combination of cow manure (PKS) and NPK fertilizer. With the following details: P0 = Control, P1 = PKS 200 g + NPK 5 g, P2 = PKS 400 g + NPK 10 g, P3 = PKS 600 g + NPK 15 g, P4 = PKS 800 g + NPK 20 g. The treatments were repeated 3 times so that there were 15 experimental units. Each experimental unit used 5 polybags and each polybag was planted with one plant so that the total cabbage plants used were 75 plants. The variables observed were leaf area, time of crop formation, crop weight, and crop volume and root volume. The results showed that the combination of cow manure and NPK fertilizer had a significant effect on the growth of leaf area, crop weight, and crop volume. However, it has not had a significant effect on the time of crop formation. Treatment of cow manure 800 g + NPK 20 g (P4) fertilizer increased crop weight and crop volume. Treatment of cow manure 400 g + NPK 10 g (P2) fertilizer increased cabbage leaf area.

Abstract

Oil palm is one of the important plantation commodities in Indonesia, with a plantation area reaching 14.33 million hectares and continuing to grow. This growth has led to an increase in the number of oil palm processing factories, which produce solid waste of Empty Fruit Bunches (EFB) and liquid waste of Palm Oil Mill Effluent (POME). If not processed properly, this waste can pollute the environment. However, this waste can be used as organic fertilizer that is rich in nutrients, reducing dependence on inorganic fertilizers, and saving costs. At the Rama-Rama Oil Palm Plantation, this waste is used as a soil conditioner and source of nutrients, with the hope of increasing oil palm productivity. This study aims to determine the effect of EFB and POME applications on oil palm productivity by comparing productivity between land applied with EFB and POME using the Independent T Test method at a real level of 5%. The results of observations show that POME and EFB applications affect the production of fresh oil palm fruit bunches, the number of fresh oil palm bunches, and the weight of oil palm bunches. POME application has a greater impact on the production of fresh oil palm fruit bunches, the number of fresh oil palm bunches, and the weight of oil palm bunches compared to EFB application and without POME and EFB application. The average production of fruit bunches in the EFB and POME blocks each month is above its production potential according to the land suitability level of class S2.

Abstract

Wood production in Indonesia continues to increase every year. Sengon plant propagation is done using seeds. The problem with the propagation of sengon plants in Indonesia is the lack of availability of prime sengon seeds. This research aims to determine the effect of concentration, soaking time, and the interaction between concentration and soaking time of Polyethylene Glycol 6000 (PEG 6000) on the length and number of leaves of deteriorating sengon (Paraserianthes falcataria L.) seedlings. The research was carried out in the greenhouse of the Faculty of Agriculture, Universitas Pembangunan Nasional “Veteran” Jawa Timur. This research used a two-factor completely randomized design (CRD) with twenty treatment combinations and three replications. The first factor is the concentration of Polyethylene Glycol 6000 (PEG 6000) which consists of 0% peg 6000; 10% PEG 6000; 15% PEG 6000; 20% PEG 6000; and 25% PEG 6000. The second factor is the soaking time which consists of 6 hours, 12 hours, 18 hours and 24 hours. Observations include the height and number of leaves of the seedlings. The results showed that giving a concentration of 15% PEG 6000 gave better results for seedling height and number of leaves. The soaking time for PEG 6000 for 12 hours gave better results for the height of sengon seedlings and the soaking time for 18 hours gave better results for the number of leaves. The combination of concentration and soaking time for PEG 6000 showed no real interaction.
