Abstract

Kejadian cuaca ekstrim mengacu pada curah hujan yang tinggi dan angin kencang telah berspekulasi merugikan produksi beras. Namun, studi tentang mekanisme morfologi dan fisiologis, dan strategi adaptasinya pada penginapan jarang dilaporkan. Dengan demikian, tiga percobaan dilakukan di Sawah Baru, Leuwikopo, dan Provinsi Lampung, Indonesia dari Januari 2016 hingga Juni 2017. Hasil penelitian menunjukkan bahwa cuaca ekstrem menyebabkan tanaman padi tersangkut di daerah penelitian sebesar 27,6% dengan kehilangan produksi hingga 11,89%. Adaptasi morfologi dan fisiologis tampaknya merupakan aspek penting dalam respon terhadap perlakuan cuaca ekstrim. Komposisi biokimia berubah setelah penginapan, terutama asam lemak, terpene, alkana, dan steroid. Penginapan meningkatkan total senyawa biokimia lebih dari 48% dari tanaman normal. Berbeda dengan kehilangan produksi yang nyata pada petak percobaan, di lapangan, dampak cuaca ekstrim terhadap penurunan produksi padi di Provinsi Lampung tergolong rendah, yaitu 1,03%. Pergeseran produksi padi antar agroklimat, meminimalkan dampak cuaca ekstrim. Kemungkinan kemampuan lokal untuk mempertahankan peningkatan produksi tahunan lebih dari 5% melalui perluasan lahan irigasi, varietas unggul dan subsidi input merupakan faktor penting sebagai strategi lokal untuk beradaptasi dengan kejadian cuaca ekstrim di Lampung.

Abstract

Edamame was a commodity that contains all types of essential amino acids that can stabilize blood sugar levels, increase metabolism and energy levels, and help build muscle and immune system cells. Farmer’s interest in planting edamame is high due to the high demand and promising commodity prices. However, edamame is often faced with weed disturbances. The weeds in edamame cultivation can reduce production in quantity and quality. Research is needed for effective weed control techniques to reduce losses and increase production plus increasing income. The research was conducted at the Lampung State Polytechnic from April to September 2020. The study was arranged using a randomized block design with single factor treatment in the form of weed control techniques with 4 treatments and 3 replications. The aim of this research was to find the best weed control techniques in edamame cultivation. The results of this study were using mulch can reduce weed growth by 75.75% to 95.45% compared without using mulch. The highest pressure on weed growth was obtained from the used plastic mulch as a weed control technique.

Abstract

To mitigate the impact of extreme weather incidents, rice cultivars Way Seputih (WS) and Way Apo Buru (WAB) were evaluated under simulation of continuous wind and rainfall treatments. The research was conducted from July to October 2017 at Leuwikopo Experimental Farm, Bogor, Indonesia. For 15 days at day time, flowering rice hills were treated with about 100 mm/h water shower (Experiment-1), and with 0, 10-15, 20-25 and 35-40 km/h wind velocity (Experiment-2). Results showed that wind and rainfall treatments reduced rice production; the effect depended on the genotypes and flowering stage. Rain treatment from panicle emergence to 50%-emerged increased the number of unfilled grains by 154.6-182.3% and 55.7-101.9% in WS and WAB cultivars, respectively. Rain treatment at 100%-emerged had no effect on WS, but it increased unfilled grain (163.5%) and decreased grain index (12.9%) in the WAB cultivar. Wind speed at 35-40 km/h promoted a high percentage of grain drop (25.7%) and unfilled grains (77.3%), and low grain index (20.8 g) in WS genotype. WAB was more tolerant of wind stress than the WS. The present experiment showed that genotype had different responses to wind and rain treatments implying different mitigation strategies should be applied through genotype selection.

Abstract

The presence of weeds in paddy rice crops results in a decrease in yields. Appropriate weed control methods are needed as an effort to reduce potential production losses. The first step to find out the right way to control weeds is by identifying the dominance and diversity of existing weeds. This study aims was to determine the dominance and diversity of weeds in organic and conventional paddy fields. This research was conducted in organic and conventional paddy fields of Lampung State Polytechnic, Lampung Province from October to December 2022. Weeds were observed on the 0.5 m2 quadrant method with 10 replications. The data were analyszed to find the Summed Dominance Ratio (SDR) value to determine the dominant weed and the Shannon - Wiener index (H') value to determine weed diversity. The identification results showed there were 11 weed species in organic land and 7 weed species in conventional land. Broadleaf weeds were the most dominant weeds in both land areas, namely Monochoria vaginalis in organic rice fields and Spenochlea zeylanica in conventional rice fields. The results of the weed diversity index analysis showed that in both land areas fall into the category of moderate diversitywith the value of  2.31 in organic rice fields and 1.93 in conventional rice fields.

Abstract

Aluminum stress is a limiting factor for crop production on acid dry land with a low pH. The objectives of this study were to evaluate aluminum-tolerant upland rice varieties in acid dry land. The study was carried out using a completely randomized block design (RCBD) consisting of 8 varieties, namely IR64, Inpago 7, Dodokan, Dod-Pup1, Situ Bagendit, Situ Bg-Pup1, Batur, Batur-Pup1, and 4 strains, namely 19 (PB5)-2, 20 (PB8)-1, 21 (PB15)-1, and 22 (PB16)-1. The results showed that the Situ Bagendit variety with the Pup-1 locus gave the highest yield per plot compared to other varieties and lines, namely 287.5 g. These results also correlate with the ability of the variety to withstand aluminum stress, with a tolerance value of 3.00 (rather tolerant).

Abstract

Fall Armyworm pests are polyphage pests that attack food and horticultural crops and can cause very large losses. The purpose of the efficacy test is to determine the effectiveness of insecticides with active ingredients Spinetoram in an effort to reduce the attack of Spodoptera frugiperda larvae and determine the symptoms of caterpillar death against the active ingredient Spinetoram. This activity is carried out in Karawang Research Farm PT Corteva Agriscience Indonesia (Research and Development Karawang) located at Jalan Selang, Ciwaringin, Lemahabang, Karawang Regency in May 2023. The activities carried out include rearing FAW in the preparation of test insects, grouping test insect larvae, and making active ingredient solutions, then the method used is the bioassay method by dipping young corn leaves into the active ingredient solution and drying the wind. Mortality observations were made ranging from 3, 6, 9, 12, 24, and 48 HAA to determine LC50 and LC95. Based on the results of the discussion, it can be concluded that LC50 is obtained at 3 JSA, namely P1 (0.47 ml /L) of 60%, P2 (0.59 ml/L) is 64%, P3 (0.71 ml/L) is 74%, and P4 (0.83 ml/L) is 66%. LC95 was obtained at 24 HAA for P1 (0.47 ml/L) and P2 (0.59 ml/L) at 98%. In 48 HAA, all treatments were obtained at 100%. Symptoms of death are very specific to the body of the larva Spodoptera frugiperda on P4. Keyword: Spinetoram, Spodoptera frugiperda, Bioassay.
