Abstract

Penelitian ini mengaplikasikan tiga tingkatan naungan, yaitu: 40%, 75% dan 85% terhadap pertumbuhan tinggi bibit buah jentik. Tujuan penelitian adalah menemukan tingkat naungan optimum bagi pertumbuhan tinggi bibit buah jentik.Manfaat penelitian adalah memberikan informasi tentang bagaimana mempercepat pertumbuhan tinggi bibit buah jentik di persemaian. Metode analisis yang digunakan adalah Rancangan Acak Lengkap (RAL), yang dilanjutkan dengan Uji Duncan.Perlakuan naungan menggunakan tiga tingkatan, dan setiap tingkatan menggunakan satu bibit dengan sepuluh ulangan, sehingga total bibit yang digunakan adalah 30 batang. Hasil penelitian menunjukkan bahwa tingkat naungan 85% atau intensitas cahaya 15% memberikan pertumbuhan tinggi paling optimum (1,15 cm) bagi bibit buah jentik, yang diikuti oleh tingkat naungan 75% (0,77 cm), tingkat naungan 40% (0,77 cm) selama tiga bulan.Naungan 85% mengaktifkan auksin pada bagian pucuk bibit sehingga memacu pertumbunan tinggi, sedangkan tingkat naungan 40% memberikan pertambahan tinggi paling rendah.Kata kunci: pengaruh, naungan, pertumbuhan, jentik, bibit.

Abstract

Utilizing natural growth regulatorshas been developed widely beside utilizing the artificial one.  Comparing the two growth regulators is needed in order that it is found  more effective ones on the cutting growth. The study aimed to analyze the growth sensitivity of cinnamon cuttings on Rootone-F (synthetic hormones),coconut water and red onion extract (natural hormones). A completely randomized design was employed in the experimental design. The analysis of variance was done with theStatistical Package for Social Sciences 17.0 software aid. The results showed that thegrowthvariables of cinnamon: the budding rates were sensitive to the red onion treatment, and the length of roots were sensitive to the coconut water treatment. Yet, the overall results showed that the Rootone-F treatment provided constant effects on increasing the the growth of branch cuttings of cinnamon. The most important factor determining the success of cutting growth is root growth. The highest percentage growth of roots (90%) was achieved through the treatment of Rootone-F with a dosage of 30 mg/cut. However, its effects did not differ from the effects of other treatments.Keywords: cinnamon cuttings; Rootone-F, young coconut water, red onion extract

Abstract

The research aimed to analyze the growth response of belangeran (Shorea balangeran) seedlings on the water of palm oil empty bunches and dolomite lime. The research used a method of a completely randomized design, with the treatments: dolomite lime water, oil palm empty bunch water, and peat swamp water as a control. Based on the ANOVA, the treatment had a very significant effect on the increase of height and diameter of the seedlings. The dolomite lime water increased the seedling height of 9.434 cm, followed by oil palm empty bunches with height increase of 6.800 cm, and peat swamp water/control  with the increase of 5.434 cm. Based on the LSD test, the height increase by dolomite lime water treatment was very significantly different from the height increase by oil palm empty bunches water and the height increase by peat swamp water. The water treatment of empty oil palm bunches increased diameter of 0.156 cm, followed by dolomite lime water with the increase  of 0.147 cm, and peat swamp water with the increase of 0.128 cm. Based on the LSD test, the increase in diameter by the oil palm empty bunches was very significantly different from the diameter increase by the control, but was not significantly different from the increase diameter by the dolomite lime water. It is advisable to mix peat swamp water with dolomite lime with a concentration of 100 grams/200 liters or oil palm empty bunches with a concentration of 5 empty bunches/200 liters of water before using it to water the belangeran seedlings.

Abstract

The objective of the study was to test the effectivity of rootone-F, young coconut milk, and onion extract on triggering the growth of the cuttings of pasak bumi stems. The method used to test the variance of data was a completely randomized design. The least significance difference  and the Duncan tests were used to test the effects of treatments. The results showed that the treatment of rootone-F (100 mg/cutting) significantly (99%) affected the budding rates and bud length of the cuttings of pasak bumi stems. Young coconut milk with concentration of 75% significantly (99%) affected the bud length, and significantly (95%) affected the budding rate. Onion extract with concentration of 150 g/1 liter water significantly (99%) affected the budding rate of pasak bumi stem cuttings, and significantly (95%) affected the bud length. The best treatment was the rootone-F treatment with a dosage of 100 mg/cutting in the paste form for triggering the budding of pasak bumi stems.Tujuan penelitian ini adalah untuk menganalisis efektivitas rootone-F, air kelapa muda, dan ekstrak bawang merah dalam merangsang pertumbuhan stek batang pasak bumi. Metode yang digunakan untuk menguji data keragaman adalah rancangan acak lengkap. Untuk menguji pengaruh masing-masing perlakuan, digunakan uji beda nyata terkecil dan uji Duncan. Hasil penelitian menunjukkan bahwa perlakuan rootone-F dengan dosis 100 mg/stek berpengaruh sangat nyata terhadap kecepatan bertunas dan panjang tunas stek batang pasang bumi. Perlakuan hormon tumbuh air kelapa muda dengan konsentrasi 75% dengan merendam stek selama 18 jam berpengaruh sangat nyata terhadap panjang tunas, tetapi hanya berpengaruh nyata terhadap kecepatan bertunas stek batang pasak bumi. Perlakuan hormon tumbuh ekstrak bawang merah dengan konsentrasi 150 g/1 liter air dengan merendam stek selama 5 jam berpengaruh sangat nyata terhadap kecepatan bertunas, namun hanya berpengaruh nyata terhadap panjang tunas stek batang pasak bumi. Perlakuan terbaik adalah pemberian rootone-F dengan dosis 100 mg/stek yang dibuat dalam bentuk pasta.
