Abstract

Armyworm (Spodoptera litura) is one of the pests that attack vegetable plants in Indonesia. The attack resulted in the leaves of the plant being cut and perforated so as to reduce productivity and even crop failure The aim of the study was to determine effectiveness of Tithonia diversifolia extract as a vegetable insecticide to control the Spodoptera litura in mustard plants at the laboratory. The study used a completely non-factorial randomized design consisting of 5 treatments, K0 = no extract (control), K1 = concentration 4%, K2 = concentration 6%, K3 = concentration 8%, K4 = concentration 10%. Parameters observed were morphological changes and insect behavior, percentage of larval mortality, percentage of pupae and imago formed. The results that Tithonia diversifolia extract can control Spodoptera litura. The result of 8% (K3) Tithonia diversifolia extract effectively controls Spodoptera litura. The highest percentage of larval mortality of Spodoptera litura (80%) was found in the treatment of K3 (concentration 8%) at observation 9 HSA and the lowest mortality was found in K1 (concentration 4% with an average 67.5%. The lowest formation of pupa and imago in the K3 treatment was 20 and 29.17%

Abstract

The aim of the study was to examine the effectiveness of various extracts of vegetable insecticides in controlling armyworm (Spodoptera litura) on mustard plants. The study was carried out in Sampali Village, Percut Sei Tuan District, North Sumatra, from May to June 2019. Effectiveness of Vegetable Insecticides on Death Rate Grayak caterpillars, plant height (cm) and mustard production per plot (g). The results showed that the application of botanical insecticides had a very significant effect on observations 17, 19 and 21 day after planting on the mortality of armyworms, as well as the intensity of damage to the mustard plant. Effectiveness of Vegetable Insecticides (%) on the Death Speed of Grayak Caterpillars where 50% tuba root had the highest effectiveness. (63,30) and the production of mustard greens also showed a very significant difference. It can be seen that the use of tuba root as a vegetable insecticide is quite effective in controlling armyworm (Spodoptera litura) on mustard plants.

Abstract

Onion is one of predominant flavor in Indonesia culinary which its quantity should be increased contantly. The aim of research was to invesitigate the respond of onion growth toward the treatment combination between POC cabbage and Tree types of fruit skin. This research was performed in a Factorial Randomized Block Design (RBD), which consists of 2 treatment factors, namely: 1) compost 2) liquid organic fertilizer of cabbage waste. The parameters observed in this study were plant height, number of leaves, number of tubers per sample plant, production per sample, production per plot and percentage of plant disease attack. As for the results obtained from this study, namely: 1) Giving various types of fruit skin compost did not significantly affect height, number of leaves, number of tubers, production per sample plant and production per plot of onion plants; 2) liquid organic fertilizer cabbage application has no significant effect on height, number of leaves, number of tubers and production per sample plant, but has a significant effect on production per plot of onion plant; and 3) Combination between the fruits compost and the liquid organic fertilizer that is not real influence on the plant height, the number of leaves, the number of bulbs and production per crop samples, but the effect is very real towards production per plot of the anion plants

Abstract

ABSTRAKTujuan penelitian ini untuk menganalisis kinerja rantai pasok usaha mikro kecil dan menengah pada usaha sapu lidi di daerah penelitian menggunakan metode Analytical Hierarchy Process (AHP. Sampel dalam penelitian ini adalah pemasok bahan baku dan pengusaha sapu lidi yang terdiri dari 5 orang pemasok dan 30 orang pengusha sapu lidi. Lokasi penelitian terletak di Kabupaten Deli Serdang yang berjarak 22 km dari Kota Medan. Berdasarkan hasil penelitian dapat disimpulkan bahwa secara umum, rantai pasok usaha mikro kecil dan menengah pada usaha sapu lidi di daerah penelitian ini adalah pemasok - pengusaha sapu lidi - pedagang pemasar konsumen. Kinerja rantai pasok di daerah penelitian sudah cukup konsisten dengan nilai rasio konsistensi sebesar 0,083 dengan adanya kerjasama yang baik dari kemitraan seperti pemasok bahan baku yang saat ini masih dapat memenuhi permintaan dari para pengusaha, kemudian konsistensi yang diperoleh dari metode ini juga berhubungan dengan tenaga kerja yang cukup terampil membantu mengembangkan usaha dan dapat menunjang perkembangan pemasaran produk.Kata Kunci : Rantai Pasok, Sapu Lidi, Pengusaha, AHP

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk cair Bayprint dan media sekam padi sebagai media tumbuh tanaman terhadap pertumbuhan dan produksi jagung manis. Penelitian dilaksanakan dengan menggunakan Rancangan Acak Kelompok (RAK) faktorial dengan faktor yang diteliti, yaitu: perlakuan sekam padi dan pupuk cair Bayprint. Faktor sekam padi (P) yang terdiri dari: P0 = tanpa sekam, P1 = 2 kg/plot, P2  = 4 kg/plot dan P3 = 6 kg/plot.  Faktor pupuk cair Bayprint (B) yang terdiri dari: B0 = tanpa pupuk cair Bayprint, B1 = 1 cc/l air, B2 = 2 cc/l air dan  B3 = 3 cc/l air. Parameter yang diamati adalah tinggi tanaman, diameter batang, jumlah daun, panjang tongkol, dan berat tongkol per plot. Hasil penelitian menunjukkan bahwa perlakuan sekam padi hingga dosis 6 kg/plot dapat  meningkatkan tinggi tanaman, diameter batang, panjang tongkol, berat tongkol per tanaman, tetapi tidak berpengaruh terhadap jumlah daun tanaman jagung manis. Perlakuan pupuk cair Bayprint hingga konsentrasi 3 cc/l air dapat  meningkatkan tinggi tanaman, diameter batang, panjang tongkol, berat tongkol per tanaman, tetapi tidak berpengaruh terhadap jumlah daun tanaman jagung manis. Tidak ada interaksi  antara sekam padi dan pupuk cair Bayprint terhadap semua parameter yang diamati.
