Abstract

Tanaman kedelai termasuk satu diantara beberapa komoditas tanaman pangan yang memiliki nilai ekonomi penting. Produksi kedelai di Sulawesi Tengah pada tahun 2015 sebesar 13.270 ton biji kering, turun sebesar 3.129 ton dibanding produksi tahun 2014 sebesar 16.399 ton.  Penurunan tersebut disebabkan adanya penurunan luas panen sebesar 3.044 ha, dengan produktivitas sebesar 2,53 ku/ha. Penelitian ini bertujuan mengetahui pengaruh berbagai dosis pupuk kandang ayam bentuk padat dan cair terhadap pertumbuhan dan produksi tanaman kedelai. Penelitian menggunakan Rancangan Acak Kelompok dengan dua faktor. Faktor pertama yaitu konsentrasi pupuk kandang cair, yang terdiri dari dua taraf yaitu 20 ml/L dan 40 ml/L. Faktor kedua yaitu pupuk kandang ayam padat yang terdiri dari empat taraf yaitu tanpa pupuk kandang ayam, 1000 gr, 1500 gr, dan 2000 gr. Hasil penelitian menunjukkan bahwa kombinasi pupuk kandang cair dan padat terbaik pada perlakuan 40 ml pupuk kandang ayam cair dengan 2000 gr pupuk kandang ayam padat memberikan hasil terbaik terhadap pertumbuhan dan produksi tanaman kedelai

Abstract

Salah satu faktor yang menyebabkan penurunan produksi kakao yaitu serangan hama penggerek buah kakao. Semut hitam (Dolichoderus thoracicus) diketahui sebagai agen hayati pengendali hama penggerek buah kakao. Penelitian ini bertujuan untuk menghitung kemampuan memangsa semut hitam pada larva penggerek buah kakao, dan menghitung persentase larva penggerek buah kakao yang dimangsa serta mengukur potensi semut hitam sebagai agen hayati penggerek buah kakao. Penelitian ini di laksanakan di Desa Jaya Makmur Kecamatan Nuhon Kabupaten Banggai. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 6 perlakuan dan 3 ulangan, dengan masing-masing perlakuan sebagai berikut : P1 (20 larva:10 predator), P2 (20 larva:15 predator), P3 (20 larva:20 predator), P4 (20 larva:25 predator), P5 (20 larva:30 predator), P6 (20 larva:35 predator).

Hasil penelitian menunjukkan bahwa perlakuan semut hitam pada larva penggerek buah kakao (Conopomorpha cramerella) berpengaruh sangat nyata terhadap larva penggerek buah kakao. Jumlah larva penggerek yang dimangsa tertinggi pada perlakuan P6 (20 larva:35 predator) dua minggu setelah aplikasi dengan nilai rata-rata 16,3 kemudian satu minggu setelah aplikasi dengan nilai rata-rata 14,3. Persentase jumlah larva penggerek yang dimangsa tertinggi pada perlakuan P6 yaitu 81% pada saat dua minggu setelah aplikasi dan 0,71% pada saat satu minggu setelah aplikasi.

Persentase jumlah larva penggerek yang dimangsa tertinggi pada perlakuan P6 yaitu 81% pada saat dua minggu setelah aplikasi dan 0,71% pada saat satu minggu setelah aplikasi. One of the factors that caused the decline in cocoa production was the attack of cocoa pod borer. Black ants (Dolichoderus thoracicus) are known to be biological agents to control cocoa pod borer. This study aims to calculated the ability to prey on black ants in the cocoa pod borer larvae, the percentage of cocoa pod borer larvae that are eaten and to measured the potential of black ants as biological agents of cocoa pod borer. This research was conducted in Jaya Makmur Village, Nuhon District, Banggai Regency. The research used a completely randomized design consisted of 6 treatments and 3 replications, with each treatment as follows : P1 (20 larvae: 10 predators), P2 (20 larvae: 15 predators), P3 (20 larvae: 20 predators), P4 (20 larvae: 25 predators), P5 (20 larvae: 30 predators), and P6 (20 larvae : 35 predators). The results showed that the treatment of black ants on cocoa pod borer larvae (Conopomorpha cramerella) had a very significant effected on the cocoa pod borer larvae. The highest number of dead borer larvae was in the P6 treatment (20 larvae: 35 predators) two weeks after application with an average value of 16.3 then one week after application with an average value of 14.3. The highest percentage of borer larvae preyed on the P6 treatment was 81% at two weeks after application and 0.71% at one week after application.

Abstract

Introduction: The availability of food sources influences the abundance of insect pollinators. The interaction between plants and insect pollinators is a symbiotic mutualism. In addition, the use of a plant barrier could attract insect pollinators in foraging activities. The study aimed to determine the effect of plant barrier on the abundance of insect pollinators and the yield of chili pepper. This research was carried out on agricultural land in Lumpoknyo village, North Luwuk, Banggai Regency, in July - December 2020. Methods: The research was carried out using a randomized block design, and four treatments, namely chili plants without barriers and covered with nets (P0 or control), eggplant plant barriers (P1), plant barriers with Zinnia sp and Cosmos caudatus (P2), and tomato plant barrier (P3). Observations were made every day at the time of flowering for 14 days. Sample collection of insect pollinators is done by taking insects that visit chili flowers using a sweep net. Results: Three species of insect pollinators were collected, namely Bembecinius sp, Ceratina sp, and Nomia sp. 730 individuals were found on eggplant barriers, 660 individuals on Zinnia sp and Cosmos caudatus barriers and 592 on tomato barriers. The highest individual is Ceratina sp (810 individuals), followed by Nomia sp. (799 individuals), and Bembecinius sp (373 individuals). Chili pepper cultivation using eggplant barrier yielded 4,93 kg/plot, Zinnia sp and Cosmos caudatus barriers 3,96 kg/plot, tomato barrier 3,62 kg/plot, and the lowest yield was shown in chili pepper fields covered with insect nets. of 2,00 kg/plot. Conclusion: The barrier system using eggplant is considered effective for increasing the abundance of insect pollinators and the yield of chili pepper.

Abstract

Walang sangit (Leptocorisa acuta thumb) is found in rice plants from flowering to harvest. These insects eat rice grains that are developing which have the potential to cause losses both in terms of quality and quantity. Synthetic pesticides are the main alternative for controlling walang sangit because they offer convenience and provide significant results on production per hectare. There have been many reports of the toxicity of synthetic pesticides which have negative effects including contamination of water and soil resources, loss of natural enemies of pests and insect pollinators which disrupt ecosystem functions. Utilization of plant materials with the potential for botanical pesticides is a safe control alternative for the environment and living things. The aim of the research was to determine the effectiveness of various plant materials with the potential of vegetable pesticides (extracts of maja fruit, sirsak leaves and lemon grass) against the activity of the walang sangit pest (L.acuta thumb) and to obtain plant materials with the best potential of vegetable pesticides. The study was carried out using a randomized block design consisting of 4 treatments (water, maja fruit extract, sirsak leaf extract and lemongrass extract ) with a concentration of 30% for each treatment which was repeated 3 times, so there were 12 experimental plots. Treatment P1 (maja fruit extract) was a treatment capable of suppressing the highest attacks of walang sangit with an average attack intensity of 19.44% and the lowest was treatment P0 (control) with an average attack intensity of 85.33%. The results of the 5% BNT test showed no significant difference between treatments P1, P2 and P3, but significantly different from treatment P0 in terms of controlling the locust pest (L.acuta thumb).
