“…It shows that one of the responses of plants toward drought is their activity of reducing the amount of transpiration Bouman and Tuong (2001) by rolling, reducing the area and aborting the leaves. The results of study by Hidayati et al (2017) on mastwood plants also showed a significant decrease in the number of leaves after experiencing drought stress. Research on black locust (Anggraini et al, 2016) has revealed that plant height is lower when a plant is planted in least water availability.…”

Sidaguri (Sida rhombifolia) is a wild plant with the ability to cure various diseases. Continuous exploitation of natural source can reduce the sustainability of this plant species. On the other hand, this plant is often ignored because it is considered as weed. This study aims to provide information about proper cultivation of Sidaguri to the community and medicinal plant farmers in order to maintain its sustainability and its potential to be used as cultivated plant. The study used a Completely Randomized Design (CRD) with two treatment factors: transplanting techniques (puteran, cabutan, stump) and water availability (50, 37.5, 25, 12.5% water field capacity). Observation data were analyzed by analysis of variance and followed by DMRT test at 5% upon the significant result. The results have revealed that the transplanting technique of transplanting tillers with puteran technique produces the best growth and 25% water availability increases plant growth and yield. The result suggests that Sidaguri is a plant that is tolerant to drought.

“…Penebalan korteks yang terjadi merupakan mekanisme untuk memperbanyak sel-sel dalam korteks sebagai upaya untuk menyimpan lebih banyak air. Hal ini dibutktikan oleh penelitian Hidayati et al (2017) yang menunjukkan bahwa tanaman kontrol memiliki korteks yang lebih tebal dibandingkan dengan tanaman perlakuan kekeringan. Atika et al (2018) membenarkan jika giberelin dapat meningkatkan kadar air relatif pada tanaman dengan menginduksi aktivitas enzim.…”

Peanut production showed positive growth but had not been able to meet the community demands. The low productivity could be solved by providing plant growth regulators, such as GA3, and fertilizer, such as biogas sludge. The purpose of this study was to determine the anatomical and physiological responses of peanuts to the application of GA3 and biogas sludge. The research was conducted with a 4 x 2 factorial randomized block design, four levels of GA3 dose consisting of control, 50 ppm, 100 ppm, 150 ppm, and two levels of biogas sludge dose consisting of control and 70 mL / liter of water, with three repetitions so that there are 24 units. Data were analyzed statistically by the Anova test followed by the DMRT test with a significance level of 95% (α = 0.05). The results showed that there were significant differences between plant anatomical responses: metaxylem diameter (p-value = 0.006), cortical thickness (p-value = 0.001) and pith diameter (p-value = 0.021), also between physiological responses: plant height (p-value = 0,000), leaf length (p-value = 0,000) and leaf width (p-value = 0.046), of peanuts applied a combination of GA3 and biogas sludges in various concentrations. On the other hand, there was no significant difference in stem diameter (p-value = 0.117), root volume (pvalue = 0.650) and number of leaflets (p-value = 0.120), that were applied a combination of GA3 application and biogas sludges in various concentrations.

“…Berdasarkan hasil penelitian pada rata-rata pertambahan diameter batang (Tabel 2) pada kekeringan 2 bulan, terdapat hasil bernilai negatif (minus), hal ini menunjukan bahwa terjadi penurunan terhadap pertambahan diameter batang. Pertambahan diameter batang tanaman mengalami pengurangan disebabkan peranan kalium pada dosis perlakuan tersebut belum mampu membantu tanaman dalam mengadapi kekeringan selama 2 bulan, sehingga tanaman tidak dapat mempertahankan tekanan turgor sel akibatnya terjadi pengkerutan sel dan pada daun terjadi pengulungan sebagai upaya tanaman untuk mengurangi transpirasi (Hidayati et al, 2017).…”

Kelapa merupakan tanaman serba guna, kelapa genjah sesuai dijadikan sebagai kelapa muda segar dan lebih potensial disadap niranya. Indonesia memiliki kondisi iklim yang unik, menyebabkan kekeringan. Kelapa genjah rentan terhadap kekurangan air, sehingga perlu dilakukan upaya mengatispiasi kekeringan. Salah satu upaya dalam menghadapi kekeringan dengan pemberian unsur kalium. Tujuan penelitian adalah mengetahui pengaruh dosis pemberian pupuk kalium terhadap respon pertumbuhan beberapa varietas kelapa genjah di pembibitan dalam menghadapi kekeringan. Penelitian dilaksanakan di Rumah Kaca Balai Penelitian Tanaman Palma (Balit Palma) di Mapanget, Sulawesi Utara. Penelitian dilaksanakan bulan Mei sampai November 2020. Menggunakan Rancangan Acak Lengkap (RAL) Faktorial yang terdiri dari dua faktor. Faktor pertama adalah 4 varietas kelapa genjah. Faktor kedua adalah 5 perlakuan dosis pupuk KCl. Hasil penelitian diperoleh pemberian dosis pupuk kalium 110 g KCl menunjukan kecenderungan lebih baik pada parameter pertambahan tinggi tanaman pada 1 dan 2 bulan kekeringan. Dosis pupuk kalium 165 g KCl (P3) menunjukan kecenderungan lebih baik pada parameter pertambahan diameter batang pada 2 bulan kekeringan dan volume akar. Perlakuan kalium tidak berpengaruh nyata pada pertambahan diameter batang pada 1 bulan kekeringan, penambahan jumlah daun pada 1 dan 2 bulan kekeringan, kandungan klorofil, berat kering tajuk, dan berat kering akar. Pada perlakuan Varietas kelapa genjah tidak terdapat perbedaan yang nyata antara varietas pada semua parameter pengamatan dan hanya berbeda nyata pada kandungan klorofil.
