Abstract

Antagonistic fungi are a group of fungi that can suppress or inhibit the growth and development of plant pathogens.  This study aimed to isolate the fungus from the rhizosphere of the clove plant (Syzygium aromaticum L.) from two sub-districts of Leihitu Barat and Leihitu, and to test the ability of these isolates to inhibit Rizoctonia solani.  Exploration was carried out using the simple random sampling method, taking rhizosphere soil samples from clove plants from Hatu, Allang, Asilulu and Seith.  Then isolated by the dual culture method after that, identified based on the identification key book and calculated its inhibition against plant pathogens. The results showed that 10 fungal isolates were identified, namely 4 fungal genera, namely Trichoderma, Aspergillus, Penicillium and Rhyzopus.  The soil around the rhizosphere of clove plants contains antagonistic fungi that can inhibit the growth of tomato sprouting pathogens (Rhizoctonia solani).  Obtained 7 isolates of the antagonist fungus Trichoderma sp. with the results of the antagonism test showing the highest inhibition was achieved by isolates of TrichoRCTAL2 (89,52%), and the lowest percentage was by isolates of TrichoRCTAS4 (44,07%).

Abstract

The availability of clean water in the Kuber Beach tourist area is not known for certain. To determine the depth and characteristics of the aquifer, the rock resistivity measurement was carried out using the geoelectric method with Schlumberger configuration on two tracks with a span of 200 m each. The results showed that the semi-confined aquifer was at a depth below 8 m from the ground surface. Aquifers with sand lithology have low potential, while limestones have medium potential.

Abstract

Nutmeg (Myristica fragans Houtt) is one of the plantation crops that has high economic value in addition to cloves, rubber, coffee, tea and cocoa. To get good plant growth, quality seeds are needed and to get good seeds, sufficient nutrients are needed for the growth of roots, stems and leaves. Planting media in nurseries must be of good quality so that the seeds produced are also of good quality, one of the quality planting media is using sago ela compost and using young coconut water as a growth regulator. This study aims to obtain the optimal dose of sago ella compost and young coconut water concentration on the growth of nutmeg seedlings in nurseries. The treatments used sago ella at a dose of 300 g/pot and 600 g/pot), and young coconut water with concentrations of 0%, 25% and 50%. The results showed that the sago ella treatment had a significant effect on the variables of plant height, leaf number and root length, but had no effect on stem diameter and root crown ratio, while young coconut water treatment had an effect on seedling height and number of leaves, but had no effect on root length. , stem diameter and crown to root ratio. The real interaction was only on plant height

Abstract

Rao plants are very suitable for reforestation and land rehabilitation activities because they have big trees, dense canopy and deep roots, and also strong roots. However, in its development, it still has problems, namely the low percentage of seed germination because the seeds of this species are semi-recalcitrant seeds, and have seed coat dormancy. Seed weight is thought to have a relationship with the success of germination and growth of rao plants. Therefore, the purpose of this study was to determine the relationship between seed weight and germination time and also the speed growth of germination. The method used in this study is a correlation test with a simple regression analysis approach. The variables used were the seed weight variable as the X factor, and the germination time and rates as the Y factor. The results of the study of 100 seeds of rao plants that were sampled in this study had variations in seed weight ranging from 2.1 to 5 grams. The germination time for each seed ranged from 9 – 62 days with an average growth rate of 1.8 – 3.9 cm per week. The variation in the growth time of each seed is due to the fact that the seeds of the rao plant have seed coat dormancy, but in this study there was no treatment to overcome this dormancy, so the germination process depends on the natural process of each seed. Based on the results of the study, it can be concluded that: (1) the average germination time of rao (Dracontomelon dao, Hask) seeds was 30 days, (2) seed weight was strongly correlated with seed germination time and seed germination rate, (3) seed weight increased, the germination time is longer, but the rate of growth of seed germination is faster

Abstract

Dragon fruit plants can be propagated generatively by seeds and vegetatively by propagation of branch or stem cuttings. This study aims to examine the effect of Growtone's growth regulator on the growth of red dragon fruit stem cuttings. The treatment used Growtone with three concentration levels, namely 0 (without PGR as a control), 10 g ZPT/liter water, 15 g ZPT/liter water, and 20 g ZPT/liter water. The study was designed using a Randomized Block Design with six replications. Each experimental unit consisted of 10 plants. The plant growth responses measured were shoot growth time, number of shoots, shoot length, number of roots, root length, and root dry weight. The results of the study found that PGR Growtone had an effect on shoot length, root length, number of roots and root dry weight, but had no effect on shoot growth time and number of shoots. It is better to give Growtone ZPT with a concentration of 20 g/l water

Abstract

ABSTRACTThe study aimed to obtain data on the attack intensity of Erinota thrax at different altitudes of places and find out the banana  cultivars with the lowest attack intensity.  This study used a random sampling method at three locations with different heights. The data analysis used is  a simple quantitative analysis to determine the magnitude of the attack  intensity.   The intensity of E. thrax attacks in three different places has varying percentages.  The number of leaf rolls Tulehu Village is 300 with a damage intensity  of 63.14% (heavy),   Keranjang Village was 200 with a damage intensity of 59.36% (heavy), and Tawiri Village was 187 with a damage intensity of 39.11% (medium). The greatest number of leaf rolls is 14 per leaf blade.  The lowest intensity in Tawiri Village is dominated by the cultivars of Kepok  and Emas, while the highest intensity is in Tulehu Village and Keranjang Village which is dominated by three cultivars, Raja, Kepok, and Emas. The difference in numbers between leaf rolls and larval populations is thought to be due to environmental parameters, such as wind and precipitation.
