Abstract

Mulberry (Morus alba L.) is an important commodity in the silkworm farming industry and has high economic value, thus requiring efficient propagation techniques. Vegetative propagation through stem cuttings is often constrained by a low success rate of root formation. IBA (Indole Butyric Acid), as a synthetic auxin hormone, plays a significant role in stimulating root development in plants. This study aims to determine the effect of concentration and soaking duration of the plant growth regulator Indole Butyric Acid (IBA) on the growth enhancement of mulberry (Morus alba L.) stem cuttings. The research was conducted at the Seed House of the Experimental Garden, Faculty of Agriculture, Universitas Muria Kudus, located in Gondangmanis Village, Bae Sub-district, Kudus Regency, from May to July 2024. The study employed a Completely Randomized Block Design (CRBD) consisting of two factors with three replications. The first factor was IBA concentration (K), namely K1 (100 ppm), K2 (200 ppm), and K3 (300 ppm). The second factor was soaking duration (L), namely L1 (60 minutes) and L2 (120 minutes). The results showed that different concentrations of Indole Butyric Acid had an effect on root length, time of bud emergence, and shoot length at 3 weeks after planting (WAP), while soaking duration influenced root length. A significant interaction between IBA concentration and soaking duration was observed on root length.

Abstract

Biochar is a solid material resulting from biomass carbonization which is generally made through a pyrolysis process, namely the thermal decomposition of biomass under anoxic conditions. Various previous studies have shown that biochar can have multiple positive impacts on soil quality and sugar cane productivity. Biochar can increase plant growth and development through several mechanisms, namely increasing nutrient use efficiency, increasing the amount and availability of nutrients, reducing nutrient leaching and nutrient loss through evaporation, promoting plant growth hormones, and reducing salinity stress. What is interesting is that improving the physical, chemical, and biological quality of soil by biochar allows for reducing the dose of inorganic fertilizer that must be applied to sugarcane. Biochar can be made from various local materials, including unused sugar cane biomass (dry leaves, stem shoots, litter, etc.) and sugar factory waste. Biochar can be applied together with various other materials, such as organic, biological, and inorganic fertilizers to create a more positive synergistic effect on soil quality and plant growth and development. The results of the strength-weakness-opportunity-threat (SWOT) analysis show that the advantages of using biochar based on sugar cane biomass and sugar factory waste, are 1) it is cheap and easy to obtain, 2) contributes to reducing the volume of waste, 3) is one of the carbon sequestration methods effective, and 4) can improve the physical, chemical and biological quality of the soil. The disadvantages are 1) it requires high costs for collection, storage, and transportation to the field and 2) there is high variability in the content of biochar-making materials and soil conditions. Opportunities include the need for farmers to reduce production costs, including fertilizer costs, and increasing awareness of various parties regarding environmental issues, for example about the importance of carbon sequestration and environmentally friendly agriculture. Meanwhile, the threat is that biochar production on a large scale still seems difficult and some farmers still lack confidence or trust in biochar products.. Key-words: biochar, sugarcane biomass, sugar mill waste

Abstract

Lumut Kayen Variety Guava is a local variety of guava from Pati Regency with a greenish color, a fruit weight of 60-100 g, and a sweet taste. Research on the application of auxin and the number of entres leaves on the graft shoots of the Lumut Kayen variety has never been carried out, therefore a study was carried out to determine the effect of Indole Acetic Acid (IAA) concentration and the number of entres leaves on the growth of the graft of the Lumut Kayen variety guava shoots. The research was carried out in Jatimulyo Village, Wedarijaksa, Pati in June - August 2023. The research is a two-factor factorial experiment using a Complete Randomize Block Design. The first factor is the concentration of auxin, consisting of three levels, namely: 0, 100, and 200 ppm. The second factor is that the number of entres leaves consists of three levels, namely: 0, 2, and 4 leaves, so that 9 combinations of treatments are repeated three times. The results showed that IAA concentration had an effect on the time of bud appearance, but had no effect on the number of shoots and the number of leaves. The fastest budding time was obtained at IAA concentration treatment of 200 ppm, which was 8.22 days. The number of entres leaves affects the time of bud appearance, the number of buds, and the number of leaves. The number of 4-leaf entres gives the fastest budding time (7.65 days), the number of shoots, and the highest number of leaves at 8 weeks after grafting, which is 7.46 buds and 20.89 leaves respectively. There was no interaction between IAA concentration and the number of entres leaves on the growth of guava seedlings.

Abstract

Desa Karanggondang Kecamatan Mlonggo Kabupaten Jepara merupakan kawasan pesisir di pantai utara Jawa Tengah yang memiliki panjang garis pantai 4,8 km dengan luas daerah pantai mencapai 1.214 Ha. Lahan pasir pantai merupakan salah satu lahan marginal yang memiliki banyak faktor pembatas seperti kandungan bahan organik rendah, kesuburan tanah rendah, tinggi evaporasi, temperatur tinggi serta angin yang dapat membawa garam. Namun lahan pasir pantai memiliki potensi sebagai lahan pertanian karena arealnya yang luas dan datar, adapun faktor pembatas tersebut dapat diminimalkan melalui masukan teknologi dan modifikasi lingkungan. Petani di Desa Karanggondang enggan mengusahakan budidaya di lahan pasir pantai karena keterbatasan pengetahuan yang dimiliki. Dilatarbelakangi oleh rendahnya pengetahuan petani mengenai budidaya hortikultura di lahan pasir pantai dan potensi dari usaha tani di lahan pasir pantai itu sendiri maka keterampilan petani dapat ditingkatkan. Metode kegiatan meliputi koordinasi dengan mitra, forum group discussion, sosialisasi dan pendampingan. Melalui kegiatan pengabdian kepada masyarakat ini petani mendapatkan pengetahuan baru tentang cara bertanam bawang merah dan masukan teknologi yang dapat diterapkan pada lahan pasir pantai.

Abstract

The Rubaru shallots are resistant to various abiotic and biotic stresses, such as high salinity and Fusarium wilt disease. However, this shallot was unable to flower even after flowering was induced by cold temperatures and increasing day length, as well as polyploidy methods. Therefore, efforts are needed to increase the genetic diversity of the Rubaru variety of shallots through the induction of physical mutations with gamma ray irradiation. This research aims to determine the agronomic characteristics and radiosensitivity level of the Rubaru shallot (Allium cepa L.) resulting from gamma-ray irradiation. The research used a Randomized Complete Block Design (RCBD) with one factor, namely the dose of gamma ray irradiation (G), which consists of 5 levels as follows: G0 (control), G1 (2 Gy), G2 (4 Gy), G3 (6 Gy), G4 (8 Gy). The gamma-ray irradiation treatment had a very significant effect on agronomic characteristics, namely plant length and number of leaves, number of bulbs per cluster, bulb diameter, bulb fresh weight per cluster, bulb dry weight per cluster, and weight of the largest bulb per cluster. Gamma irradiation treatment with a dose of 2 Gy produced the highest number of bulbs and bulb diameter, with the largest weight of < 3g. Meanwhile, a dose of 8 Gy had a real effect on all parameters in inhibiting the growth of the Rubaru shallot. The calculated lethal dose (LD50) value is 6.18 Gy.
