Abstract

Chilli peppers are easily infected with anthracnose disease caused by Colletotrichum gloeosporioides. Early detection, such as temperature changes with thermal sensors before visual symptoms appear, can prevent developing more severe diseases. This study aims to evaluate the potential of anthracnose detection using thermal sensors in chilli and the intensity of anthracnose disease in applying Plant Growth Promoting Rhizobacteria (PGPR). This study used a completely randomized complete group design (RKLT). PGPR was applied twice at the seedling preparation stage and at the plant age 30 days after planting (HST). Seeds that are ready to be sown are soaked first with 3 dose treatments, namely; without pgpr as control (P0), PGPR 25 g/5 L sterile distilled water (P1) and 50 g/5 L sterile distilled water (P2). Apart from that, PGPR application was also carried out on plants aged 30 HST with no PGPR as a control (P0), a dose of 100 mL PGPR/plant (P1), 200 mL PGPR/plant (P2). The results showed that the thermal sensor has the potential as an early detection method of anthracnose disease, as seen from the difference in the temperature of chilli fruit pre-inoculation with post-inoculation by 2 - 3ºC. In addition, PGPR treatment was able to suppress anthracnose disease with the lowest disease incidence of 19,33% (P1), disease severity of 16,56% (P2) and AUDPC of 49,38 units (P1).

Abstract

The high plains are typically home to broccoli plants. The discovery of a new variety of broccoli plants for the lowlands is a gift to the communities in the lowlands. Sustainable crop cultivation efforts on broccoli plants are highly needed today, given the condition, which has been heavily degraded due to the continuous use of synthetic fertilizer without being mixed with the return of organic material into the soil. Another factor is to guarantee the condition of the crops obtained. The research is aimed at obtaining the best combination of liquid organic fertilizer and bio stimulants. This study uses an experimental method with a complete random design consisting of A = POC 150 ml/l + 4 ml, B = 200 ml + 3 ml, C = 250 ml/l + 2 ml, and D = 300 ml/LL + 1 ml. With a multiplication of 5, with the number of samples in this study, there were 4 plants. Observations are performed on variables such as plant height, number of leaves, flower diameter (crop), and fresh flower weight (crop). The results of the study show that the administration of liquid organic fertilizer in combination with bio stimulants boosts the growth of broccoli crops. at a concentration of 250 ml + 2 ml is an effective combination for plant growth, especially for plant height and weight of fresh broccoli carcasses, but not an effective dose for leaf formation.

Abstract

Mango is one of the commodities with high economic potential. One of the challenges in mango production is the attack of plant pests. The insect Mictis longicornis is a major pest of mango plants. Its attacks can cause leaves, shoots, or young branches to turn brown, wilt, dry out, and eventually fall off. Control of M. longicornis can be achieved using forest betel leaf powder, which is known to be toxic to several types of insects. The main active compounds in forest betel leaf with insecticidal properties are dilapiol and the piperamidine group. The purpose of this study is to determine the intensity of M. longicornis attacks on mango plants and to analyze the effectiveness of a simple preparation of forest betel leaf powder on the percentage of M. longicornis pest attacks on mango plants. The design used in the study was a Complete Randomized Block Design (CRBD) with a single factor, namely the type of insecticide, with four treatments: control, synthetic insecticide at a concentration of 4 ml/L (active ingredients chlorantraniliprole and thiamethoxam), forest betel leaf powder at concentrations of 7.5%, and 10%. Each concentration of forest betel leaf powder was mixed with distilled water (diluent) containing 0.1% Rinso detergent. The highest attack intensity, 98.51%, was observed in the control treatment (25 days after treatment), while the highest attack intensity before treatment, 90.11%, was observed in the 10% forest betel leaf treatment. Based on descriptive analysis, the application of synthetic insecticide was able to reduce the intensity of M. longicornis pest attacks on mango plants. Based on the Kruskal-Wallis test, the application of synthetic insecticide, 7.5% forest betel leaf powder, and 10% forest betel leaf powder did not significantly differ in the intensity of M. longicornis pest attacks on mango plants.

Abstract

Kulit pisang tanduk merupakan salah satu sumber bahan organik dapat dimanfaatkan sebagai sumber unsur hara.  Kulit pisang tanduk mengandung protein dan unsur hara seperti mengandung unsur mikro P, Ca, Mg, N, Na, Zn. Penelitian ini bertujuan untuk melihat pengaruh aplikasi pupuk organik cair (POC) kulit pisang tanduk terhadap pertumbuhan dan produksi tanaman terung. Penelitian dilaksanakan di kebun percobaan Fakultas Pertanian Universitas Muhammadiyah Jakarta dari bulan November 2020 sampai dengan Februari 2021. Penelitian menggunakan Rancangan Kelompok Lengkap Teracak (RKLT), dengan 5 perlakuan pupuk organik cair kulit pisang tanduk  yang terdiri dari : 0 ml/tanaman (Anorganik 100%), 50 ml/tanaman, 100 ml/tanaman, 150 ml/tanaman dan 200 ml/tanaman. Pengamatan pada tanaman terung dilakukan terhadap pertumbuhan dan hasil tanaman terung. Berdasarkan penelitian yang telah dilakukan diperoleh bahwa penggunaan pupuk organik cair kulit pisang tanduk dengan konsentrasi 50 ml/tanaman dapat mempengaruhi pertumbuhan tanaman terung terutama pada jumlah daun dan jumlah cabang sedangkan untuk hasil tanaman terung pada diameter buah menunjukkan adanya pengaruh penggunaan pupuk tersebut namun untuk hasil terbaik ditunjukkan dengan tanpa aplikasi (100% pupuk anorganik).

Abstract

Brotowali stems (Tinaspora crispa. L) contains compounds that can be used as vegetable pesticides. The purpose of this study was to determine the phytochemical content present in brotowali stems, and effective concentrations of brotowali on mortality of O. rhinoceros larvae. This study used a Factorial Complete Ran domized Design with 6 treatments and 3 repeats, using concentrations of 0%, 10%, 10%, 20%, 30%, 40%, and 50%. The first factor is brotowali stem extract and the second factor is the method of application. The parameters observed were yield, phytochemical compounds, mortality, time of death 50% (LT50), and Lethal concentration (LC50). The results showed that brotowali stem extract contains phytochemical compounds, namely alkaloids, flavonoids, tannins, saponins, steroids, and terpenoids.  The yield produced from the rotary evaporator is 12.6%. Giving brotowali stem extract had a very real effect on the mortality of O. rhinoceros. BNJ further tests showed that 50% treatment had a very real effect with mortality of 66.67% in the feed application method, on the 11th day with a concentration of 50% and 40% feed method, then for an effective concentration to kill O. rhinoceros larvae, 50% was a concentration of 37.23% in the feed application method while in the spray application method, it could kill O. rhinoceros larvae 50% with a concentration of 63.86%.

Abstract

One of the obstacles in rubber plant cultivation is the presence of weeds. Weeds reduce the quantity and quality of yields, interfere with the maintenance and harvesting process, and become hosts for pests and plant diseases. This study aims to determine the diversity and dominance of weeds in smallholder rubber plantations. The research was conducted in two locations of smallholder rubber plantations in Juni-Juli 2023. The first location was in Natar, South Lampung and the second location was in Negeri Katon, Pesawaran. Sample selection was done by purposive sampling method with 4 replicates. The results showed that in the Natar location there were 13 weed species, while in the Negeri Katon location there were 14 weed species. Three weed species that dominated in the two locations were Axonopus compressus, Asystasia gangetica, and Ottochloa nodosa. The A. compressus weed had the highest SDR in both locations at 20.23% in the Natar location and 18.79% in the Negeri Katon location. The results of this study can be used as a basis for determining appropriate weed control techniques.
