Abstract

Respon tanaman terhadap zat pengatur tumbuh (ZPT) tergantung pada jenis dan konsentrasi ZPT,  cara aplikasi ZPT dan varietas tanaman.  Tujuan penelitian adalah mempelajari  pertumbuhan dan hasil  bawang merah  dengan perlakuan varietas dan aplikasi ZPT giberelin dan sitokinin. Percobaan  menggunakan Rancangan Acak Kelompok Faktorial dengan 2 faktor yaitu varietas terdiri dari 3 varietas dan kombinasi konsentrasi-waktu aplikasi terdiri dari 4 kombinasi.  Varietas Bauji dengan aplikasi ZPT Pronas dua kali  dengan kepekatan 5 ml/l meningkatkan  bobot umbi segar /rumpun sebesar 30,0% dan bobot umbi kering /rumpun 40.6% dibanding tanpa Pronas, varietas Thailand dengan aplikasi ZPT Pronas dua kali dengan kepekatan 10 ml/l meningkatkan  bobot umbi segar /rumpun 30,7% dan bobot umbi kering /rumpun 33,7% dibanding tanpa Pronas, sedangkan varietas Manjung  aplikasi ZPT Pronas menghasilkan  bobot umbi  segar /rumpun dan bobot umbi kering/rumpun tidak berbeda dengan kontrol hanya meningkat 3,3% dan 3,7%.  Varietas Bauji dan Thailand mempunyai jumlah tunas, jumlah akar, diamater umbi dan diameter rumpun umbi lebih tinggi dibandingkan dengan varietas Manjung.  Jumlah akar, diameter umbi, diameter rumpun umbi meningkat dengan penyemprotan zpt Pronas dibandingkan kontrol dan penyemrpotan 2 kali pada umur 20 dan 30 HST dengan kepekatan 10 ml/l merupakan perlakuan terbaik

Abstract

Bacteria living in the digestive system of earthworms (Eudrilus eugeniae) can play a role in transforming organic compounds found in the organic matter digested by the worms into simple compounds, including compounds containing indole. During the fermentation process in vermiwash, bacteria will consume the organic matter in worm waste and produce IAA as a byproduct of metabolism. This research aims to analyse the potential symbiotic bacterial communities in vermiwash from earthworms (African Night Crawler) in producing the plant hormone IAA (Indole Acetic Acid). The research method involves collecting vermiwash from earthworms and analysing its symbiotic bacterial composition. Symbiotic bacterial isolates from vermiwash were tested for their ability to produce IAA through biochemical techniques, followed by bioinformatic analysis. The research results show that vermiwash contains a potential symbiotic bacterial community capable of producing IAA. Three isolates out of 10 types of symbiotic bacteria yielded positive results by showing a pink colour change after adding the Salkowski reagent. Therefore, these symbiotic bacteria can be utilized as a source of the plant hormone IAA, which can be used as organic fertilizer. Increased IAA production in vermiwash, can accelerate plant growth, enhance root formation, and optimize overall plant production. The application of a bacterial consortium can significantly influence the plant height, leaf area, and root length while having a non-significant impact on the stem diameter of corn.

Abstract

Desa Srimulyo berada di kecamatan Dampit terkenal dengan pisang Sang Mulyo dan Kopi Dampit. Permasalahan yang dihadapi dalam produksi pisang Sang Mulyo adalah ketersediaan bibit karena peningkatan permintaan bibit pisang sangat tinggi bahkan ada target untuk menghasilkan 1 juta bibit sampai tahun 2026. Petani sudah melakukan teknik pecah bonggol, pemisahaan anakan dari indukan. Tujuan pengabdian adalah meningkatkan produksi bibit pisang Sang Mulyo dengan aplikasi zat pengatur tumbuh (ZPT) prokar dan pronas secara ex vitro pada bonggol pisang. Metode yang dilakukan melalui diskusi untuk mengenalkan ZPT buatan dan praktek untuk aplikasi ZPT buatan. Praktek yang dilakukan adalah membandingkan ZPT buatan dan alami serta pemotongan bonggol. Petani dapat menerima inovasi pemakaian ZPT buatan karena jumah tunas yang diperoleh lebih banyak dibanding ZPT alami yang sudah dipakai petani namun masih dianggap lebih mahal dibandingkan ZPT alami. Pemotongan bonggol secara terpisah meningkatkan jumlah potongan yang busuk dan disarankan pemotongan bonggol tidak sampai terpisah satu sama lain tetapi bagian dasar bonggol masih menyatu.

Abstract

Melon consumption has increased yearly due to the number of consumers. It requires rising production and land. The limited land area encourages the implementation of hydroponics with an irrigation system. This article aims to summarize various results of recent studies regarding the development and use of smart irrigation systems based on the Internet of Things and fuzzy logic in hydroponic melon cultivation using the Nutrient Film Technique method and drip irrigation. Water requirements greatly influence melon plants from vegetative growth to fruit ripening. The provision of water is carried out using the Nutrient Film Technique (NFT) irrigation technique, and drip irrigation is more optimal, requiring smart irrigation system technology. This system focuses on water supply according to plant needs, phenological phases, and environmental conditions. Based on the literature, two types of technology have been summarized: IoT-based irrigation can save water supply by up to 90% compared to the fuzzy logic method, which is around 29%. We hoped that a smart irrigation system for melons would increase the productivity of melon plants, especially hydroponic cultivation.

Abstract

In South Kalimantan, the stunting incidence rate in 2022 will be 24.6%, more significant than the national prevalence rate of 21.6%. Tanah Bumbu is one of the districts located in South Kalimantan Province, with the incidence of stunting in Tanah Bumbu district, according to SSGI data, reaching 16.1%. Sari Gadung Village is one of the villages in Simpang Empat District, Tanah Spice Regency. This village has a potentially productive group, namely Posyandu Cadres. Data on the incidence of stunting in Tanah Spice Regency reached 16.1%. Providing health supplements to the community is needed to improve community health in Sari Gadung village and prevent stunting. This community service activity aims to prevent stunting by providing health checks, including checking Hb, glucose, uric acid, and blood pressure, and providing blood supplements. The method is that adult female patients are given drug information regarding the use of iron and folic acid drugs, and then their Hb, glucose, uric acid, and blood pressure are checked. The results of this activity showed that the number of patients who took part in the activity was 37, the average Hb value was 15.9 g/dL, the average uric acid was 8.6 mg/dL, the mean glucose was 112.5 mg/dL, and the blood pressure was 122/82 mmHg. The conclusion is that the results of the health examination at the posyandu in Sari Gadung village are still in the normal category.

Abstract

Apples (Malus sylvestris) have been grown in Indonesia, especially in highland areas such as Batu, Nongkojajar, and Poncokusumo. In order to propagate apple plants through in vitro, organ culture is performed in a controlled environment, free of pests and diseases. The research aimed to evaluate the effect of the composition of the growth regulator BAP-IAA on the growth and shoot multiplication of several apple cultivars in vitro. The research was carried out at the Indonesian Orchid Partners Laboratory Jl. Hasanudin 1 No 24 Junrejo District, Batu City, Indonesia. The four apple cultivars used were Fuji, Red Delicious, Gala, and Manalagi apples. Four types of growth regulator composition were the treatments: 3 mg L-1 BAP and 0.2 mg L-1 IAA, 6 mg L-1 BAP and 0.2 mg L-1 IAA, 3 mg L-1 BAP and 0.3 mg L-1 IAA, and 6 mg L-1 BAP and 0.3 mg L-1 IAA. The results showed that growth and yield were more precise in the combination of Red Delicious with the growth enhancer composition of 3 mg L-1 BAP and 0.3 mg L-1 IAA, as shown by the variable number of shoots and fresh weight of explants. The results showed that the combination of the Red Delicious apple cultivar with BAP 3 mg L-1+IAA 0.3 mg L-1 can be recommended as the best treatment in mass shoot production/multiplication.
