Abstract

ABSTRAK Produktivitas tanaman sorgum cukup tinggi (2,6-6 ton/ha) dan dapat dibudidayakan disegala jenis tanah, termasuk di lahan marginal (Puslitbang Tanaman Pangan, 1993). Namun ditingkat petani produktivitas sorgum masih jauh di bawah potensi hasil penelitian, yaitu antara 0,37-1,80 ton/ha (Sirappa, 2003). Penelitian ini bertujuan untuk mengetahui pengaruh pemberian biochar dan jarak tanam terhadap pertumbuhan, kadar brik batang dan hasil tanaman sorgum samurai 1. Penelitian ini dilaksanakan di Lahan Penelitian di Desa Akar-Akar, Kecamatan Kayangan, Kabupaten Lombok Utara. Penelitian dilaksakan pada bulan November-Feberuari 2019. Rancangan percobaan yang akan digunakan dalam penelitian ini adalah Rancangan Acak Kelompok (RAK) faktorial yang terdiri atas 2 faktor. Faktor 1 adalah biochar terdiri dari 3 aras: B0 (Tanpa Biochar), B1 (10 ton/ha), B2 (20 ton/ha), dan faktor 2 adalah jarak tanam terdiri dari 3 aras: J1 (75 cm x 20 cm) dengan populasi 85 tanaman, J2 (35 cm x 20 cm) dengan populasi 153 tanaman, J3 (20 cm x 20 cm) dengan populasi 157 tanaman, sehingga diperoleh 3 x 3 = 9 kombinasi perlakuan. Masing-masing perlakuan diulang 3 kali, sehingga didapat 27 plot percobaan. Hasil penelitian menunjukkan bahwa interaksi biochar dan jarak tanam tidak memberikan pengaruh yang berbeda nyata terhadap pertumbuahan, kadar brix batang dan hasil tanaman sorgum samurai 1, pemberian biochar tidak memberikan pengaruh yang berbeda nyata terhadap pertumbuahan, kadar brix batang dan hasil tanaman sorgum samurai 1, sedangkan perlakuan jarak tanam memberikan pengaruh yang berbeda nyata terhadap pertumbuhan dan hasil tanaman samurai 1. ABSTRACT Sorghum crop productivity is quite high (2.6-6 tons / ha) and can be cultivated in all types of soil, including marginal land (Center for Food Crops Research, 1993). But at the farmer level sorghum productivity is still far below the potential of research results, which is between 0.37-1.80 tons / ha (Sirappa, 2003). This study aims to determine the effect of biochar administration and planting distance on growth, stem brik content and yield of samurai sorghum 1. This research was conducted at the Research Field in Akar-Akar Village, Kayangan District, North Lombok Regency. The study was conducted in November-February 2019. The experimental design that will be used in this study is a factorial Randomized Block Design (RBD) consisting of 2 factors. Factor 1 is biochar consisting of 3 levels: B0 (without Biochar), B1 (10 tons / ha), B2 (20 tons / ha), and factor 2 is spacing of 3 levels: J1 (75 cm x 20 cm) with a population of 85 plants, J2 (35 cm x 20 cm) with a population of 153 plants, J3 (20 cm x 20 cm) with a population of 157 plants, so that a 3 x 3 = 9 treatment combination is obtained. Each treatment was repeated 3 times, so that 27 experimental plots were obtained. The results showed that the interaction of biochar and plant spacing did not have a significantly different effect on the growth, stem brix content and yield of samurai sorghum 1 plants, the administration of biochar did not have a significantly different effect on the growth, stem brix level and samurai sorghum crop yield 1, whereas spacing treatment gives a significantly different effect on the growth and yield of samurai plants 1.

Abstract

Dompu Regency is one of the national sugarcane development areas, which supports the target of consumption sugar self-sufficiency and then increases to national sugar self-sufficiency. In 2014, the central government has collaborated with the Dompu district government to expanding intensification of sugarcane farming, especially on dry land / moor on ​​1,000 ha of area. Shifting the function of the sugarcane development land occurs because the conversion of technical irrigation rice fields into industrial buildings and other infrastructure. To support the development of sugar cane on dry land, then the way to increase the productivity of sugarcane are by using new superior varieties of sugar cane with high production potential and high yield. The assessment of several sugar cane varieties has been implemented in Beringin Jaya village, Pekat sub-district, Dompu, in 2016 with the aim to finding out the potential production and yield of several sugar cane varieties on dry land. The design used was a Randomized Block Design, with 4 replications. The varieties tested were 5 types, that is: PS 862 (comparator); BL; PSJT 941; PS 881 and PS 851. The size of each plot is 13 x 5 m, planting distance is 130 x 50 cm (single pitch). Parameters observed: plant height (cm), stem diameter (cm), number of sections, number of tillers, brix (%), production (t / ha), and estimated yield (%). Observations made before the harvest (age 10 months). Data were analyzed using analysis of variance (Anova) DSAASTAT software Version 1.101, Italy and if there were significant differences, the analysis was continued with the LSD test at 5% level. The results of the study showed that the analysis of plant height, stem diameter and production of the tested varieties were not significantly different, whereas the number of sections, number of tillers, brix and yield estimates were significantly different. PS 851 variety produced the highest yield of 9.27% ​​and was followed by PS 862 (9.06%), PS 881 (8.46%), PSJT (98.11%), and BL (8,08%). The results of farmers' preferences on agronomic characteristics and yield components of sugarcane varieties tested on dry land showed that farmers were more dominant in choosing PS 851, PS 862 and PSJT 941 varieties.

Abstract

Aroma quality of rice in addition to determined by genetic factor is also influenced by environmental factors. One of those that significantly affected the aroma quality of aromatic upland rice is soil moisture. The stronger fragrant aroma of rice often occurs at relatively low soil moisture level, so that the grain obtained relatively low, So that when the aroma quality of rice increases, the grain yield is lower. The purpose of this research is to know the influence of soil moisture to both growth and yield components, yield as well as the aroma quality of three local varieties of aromatic upland rice from South West Sumba. The experiment was carried out factorially in a split-plot design with three replications. The first factor was the level of soil moisture with four levels, namely: 100%, 80%, 60% and 40% FC and the second factor was local varieties, namely: Lapale Kuhi, Kiku Lapale, and Panenggo. The observed variables included: vegetative and reproductive characters, physiological characters and aroma quality. The data collected were analyzed by analysis of variance followed by the Honestly Significant Difference (HSD) Test at a 5% significance level. The results showed that: 1) Yield components and grain yield were the highest at 100% Field Capacity (FC) soil moisture level, and they were significantly lower at 40% FC soil moisture level, 2) Soil moisture level also significantly affected physiological characters, namely: N, Na, proline contents , and aroma quality of rice, 3) Decreasing the level of soil moisture reduces N content of leaves tissue, increases Na and proline contents of leaves tissue. Aroma score of rice increased with a decrease in soil moisture level, whereas 2-AP compound content of rice increased at soil moisture level 80 % FC and reduced both at 60% FC and 40% FC..

Abstract

Scarification is a technique to physically damage the seed coat to reduce hard seed (while keeping the seed viable) and increase water imbibition into the seed in order to increase seed germination. This study aims to determine the effect of mechanical scarification on the viability and vigor of Moringa oleifera seeds. A greenhouse scale experiment was conducted at the Faculty of Animal Science, University of Jambi for one month. The experiment was arranged in a Completely Randomized Design (CRD) consisted of 4 treatments and 5 replications. The treatments were P0 = seed without scarification (control), P1 = seed rubbed on one side, P2 = seed rubbed on two sides and P3 = seed rubbed on three sides - the entire surface of the seed. The seeds have 7-8% moisture content and rubbed with sandpaper. Variables observed were germination rate, germination speed, simultaneity of germination, normal sprout dry weight as a viability variable, and number of leaf sub branches and plant dry weight as vigority variable. The results showed that scarification on the three side (on entire seeds coat) was very significantly (P <0.01) reduce the germination rate, germination speed, germination simultaneity, normal sprout dry weight. Meanwhile scarification on one and two side were very significantly (P <0.01) increase the number of leaf sub branches and plant dry weight compared to control. Based on the results of the study it could be concluded that on of the greenhouse scale scarification on one side of the seed and on the two sides of the seed was able to increase the viability and vigor of Moringa seed.

Abstract

The abundance of sac caterpillar populations in a oil palm plantation ecosystem is very important to know so that farmers can know the losses that can be caused and overcome the attack of sac caterpillars on oil palm plants and to know the types of natural enemies of sac caterpillars so that the control based on the IPM concept can be applied. This study aims to determine population abundance and sac caterpillars (Lepidoptera: Acrolophidae) pests and natural enemies in smallholder oil palm plantations. Sampling was carried out 3 times at the locations of Nagari Padang Laweh and Nagari Muaro Sopan in March-May 2019 using the survey method and observing sac caterpillars and natural enemies carried out by direct collection. Samples that have been obtained from each observation point are counted by the number of larvae and natural enemies. The results showed that higher rates of sac caterpillar attacks occurred in Nagari Padang Laweh. At the location in Padang Laweh, the total population collected was 793, and at the Muaro Sopan location, 41 caterpillars were found. The highest percentage of sac caterpillar attacks in the Padang Laweh location sample was 76.92%, and the lowest percentage of attacks in the Muaro Sopan location sample was 35.89%. The rate of attack of the sac caterpillar on the 9th midrib is 30.00 tails per midrib which is included in the weight category. Natural enemies found in both study sites are predators of spider types.
