Abstract

In Tanggamus, pepper trees are commonly intercropped in coffee plantations with coffee-pepper intercropping type (dominant coffee), coffee pepper type (dominant pepper), and agroforestry type. The intercropping system plays a role in improving agro-ecosystems, increasing farm productivity and income. This study aimed to study crops diversity, productivity and income of coffee-pepper intercropping farming. This study used a survey method. The survey locations were determined purposively in two sub-districts which were centers of coffee cultivation in Tanggamus, namely Ulu Belu and Air Naningan District. In the Ulu Belu District, the villages of Sinar Banten, Sinar Galih, Petai Kayu were selected purposively, and in the Air Naningan District were Datar Lebuay Village and Air Kubang Village. Primary data was collected by visiting plantations and interviewing farmers. Sample farmers were determined randomly with a total of 137 samples. The diversity of intercrops was analyzed by calculating the Benefit Index Value and Importance Value Index. The results showed that coffee plantations were generally intercropped (79-86%) with coffee and pepper. Based on the Importance Value Index, in Ulu Belu the most important intercrops were pepper, banana, avocado and cayenne pepper, while in Air Naningan they were pepper, jengkol, cayenne pepper and durian. The income of intercropping coffee farmers could reach IDR 24 million/hectare/year. This income was obtained from both the coffee-pepper intercropping or the coffee-non-pepper intercropping. The productivity of intercropping coffee ranged from 528-1,097 kg/hectare. The productivity of pepper intercrops ranged from 0.45-0.54 kg per tree and contributed 11-29% of coffee income.

Abstract

Tujuan dilakukannya penelitian ini adalah untuk mengetahui efektivitas dari pencampuran herbisida dengan bahan aktif diuron dan hexazinon dalam mengendalikan gulma serta mengetahui sifat campuran kedua bahan aktif tersebut.  Penelitian ini dilakukan di rumah plastik Kecamatan Natar, Kabupaten Lampung Selatan dari bulan Mei hingga Juli 2022.  Penelitian disusun dalam Rancangan Acak Lengkap (RAL).  Perlakuan terdiri dari tiga jenis herbisida dengan enam tingkat dosis bahan aktif, yaitu herbisida tunggal diuron 80% WG (0, 0.25, 0.50, 1.00, 2.00, dan 4.00 kg ha-1), hexazinon 75% WG (0, 0.5, 1.0, 2.0, 4.0, and 8.0 kg ha-1), dan campuran herbisida dari diuron 46,8%  + hexazinon 13,2%  (0, 0.25, 0.50, 1.00, 2.00, and 4.00 kg ha-1).  Gulma sasaran meliputi dua jenis gulma golongan daun lebar (Ageratum conyzoides dan Asystasia gangetica), golongan rumput (Eleusine indica dan Paspalum conjugatum), serta golongan teki (Cyperus kyllingia dan Cyperus rotundus).  Herbisida diuron dan hexazinon memiliki cara kerja berbeda sehinggal metode analisis yang digunakan adalah metode Multiplicative Survival Model.  Hasil penelitian menunjukkan bahwa pencampuran herbisida diuron 46,8%  + hexazinon 13,2%  memiliki nilai LD50 harapan sebesar 69,29 g ha-1 dan LD50 perlakuan sebesar 55,77 g ha-1 dengan nilai ko-toksisitas sebesar 1,24 (ko-toksisitas > 1) sehingga campuran bersifat sinergis.

Abstract

Utilization of organic matter as a plant nutrition can be used to increase the growth and yield of melon cultivation. Fruit thinning treatment can be used to improving fruit quality. This study aims to examine the effect of various organic fertilizers and fruit thinning on the growth and yield of melons. The study was conducted in Screen house Universitas Perjuangan Tasikmalaya from March to June 2021. The study used a factorial completely randomized design. First factor is type organic fertilizer consist of solid chicken manure, vegetable waste liquid fertilizer, and cow urine. Second factor is fruit thinning consist of 1 and 2 remaining ovules. Based on the research results, the interaction of vegetable waste with the remaining 1 ovule resulted in the highest number of leaves compared to other interactions. Chicken manure and vegetable waste with 1 and vegetable waste with 2 ovules produced the greenest leaves compared to other interactions. The application of organic fertilizer had no significant effect on plant biomass, root length, fruit diameter, fruit thickness, total dissolved solids, and productivity. Fruit thinning significantly affected to plant biomass, root length, fruit diameter, fruit thickness, fruit weight per plant, and productivity. 1 ovule was the best treatment compared to 2 ovules. Provision of vegetable waste with 1 and 2 ovules affects the growth and yield of melon plants. Fruit thinning by leaving 1 ovule effectively to growth and yield of melons.
