Abstract

Permasalahan perubahan iklim dipulau Lombok khususnya di Kabupaten Lombok Barat, hal ini menjadi faktor utama dalam melaksanakan kegiatan produksi pertanian di wilayah Kabupaten Lombok Barat. Salah satu upaya yang harus dilakukan dengan analisis tipe iklim dengan menggunakan metode Oldeman agar dapat mengetahui kebutuhan air tanaman serta curah hujan pada wilayah tersebut. Tujuan dari penelitian ini yaitu, untuk mengetahui mengetahui tipe iklim di beberapa Kecamatan di Lombok Barat berdasarkan klasifikasi iklim menurut Oldeman. Metode yang digunakan dalam peneltian ini adalah metode deskriptif, yang dimulai dengan pengumpulan data dari badan meteorologi, klimatologi dan geofisika., menganalisis data dan menginterpetasi data. Analisis tipe menurut Oldeman pada dasarnya menentukan jumlah bulan basah, bulan kering dan bulan lembab yang dimana jumlah bulan basah > 200 mm, bulan kering < 100 mm dan bulan lembab 100-200 mm. Hasil yang diperoleh dari penentuan tipe iklim pada beberapa Kecamatan yaitu pada Kecamatan Kediri bertipe iklim C3, pada Kecamatan Narmada D3, pada Kecamatan Lembar D3 dan pada Kecamatan Gerung bertipe iklim E3.

Abstract

Abstrak: Tanaman tembakau Virginia (Nicotiana tabacum L) merupakan salah satu komoditas tanaman pertanian yang banyak dibudidayakan di Pulau Lombok. Pestisida dengan bahan aktif Imidakloprid dan Pendimetalin merupakan salah satu jenis pestisida yang banyak digunakan oleh petani tembakau di Pulau Lombok. Penggunaan pestisida yang berlebihan dan tidak tepat dapat mengakibatkan pencemaran lingkungan, salah satunya dapat meninggalkan residu di dalam tanah, tanaman, dan air. Tujuan dari penelitian ini adalah untuk mengetahui status residu insektisida berbahan aktif Imidakloprid dan herbisida berbahan aktif Pendimetalin di lahan sawah petani tembakau Virginia di Pulau Lombok. Hasil analisis laboratorium menunjukkan bahwa residu insektisida berbahan aktif Imidakloprid dan herbisida berbahan aktif Pendimetalin di lahan sawah petani tembakau Virginia di Pulau Lombok tidak terdeteksi adanya residu pada alat kromatografi dengan batas minimum deteksi 0,10 ppm. Kata Kunci: Imidakloprid, Pendimetalin dan Residu Abstract: Virginia tobacco plant (Nicotiana tabacum L) is one of the most widely cultivated agricultural commodities on Lombok Island. Pesticides with the active ingredients Imidacloprid and Pendimetalin are a type of pesticide that is widely used by tobacco farmers on Lombok Island. Excessive and inappropriate use of pesticides can lead to environmental pollution, one of which can leave residues in soil, plants and water. The purpose of this study was to determine the residual status of the insecticide with the active ingredient Imidacloprid and the herbicide with the active ingredient Pendimetalin in the paddy fields of Virginia tobacco farmers on Lombok Island. The results of laboratory analysis showed that residues of the insecticide with the active ingredient Imidacloprid and the herbicide with the active ingredient Pendimetalin in the paddy fields of Virginia tobacco farmers on Lombok Island were not detected by the chromatography tool with a minimum detection limit of 0.10 ppm.

Abstract

This study aims to determine the effect of orrin liquid fertilizer on the growth and yield of cayenne pepper and red peppers on Entisol.  The research method used is an experimental method, carried out on farmer-owned land in Kediri village, Kediri District, West Lombok Regency from June to October 2023. The study consisted of two experimental units consisting of one unit for cayenne pepper and another unit for red chili, The experimental design used was a randomized group design, with the treatment of orrin liquid fertilizer concentration (0, 10, 20) ml / L Each treatment was repeated three times and the data observed were analyzed using analysis of variance, while the different treatment was further tested using BNJ 5%. The outcomes showed that the treatment of orrin fluid manure application didn't influence the development of cayenne pepper and red bean stew plants which include: plant level, number of leaves and number of stem branches), yet impacted the yield parts which include: organic product weight and number of natural products. While the timeframe of realistic usability of cayenne pepper can arrive at 35 days and red pepper 45 days without decay.

Abstract

This study was aimed to determine the influence of various kinds of manure on N and P uptake on Golden berry (Physalis angulata L.). The experiment was conducted in a plastic house in Terong Tawah, Subistrict of Labuapi, West Lombok regency. The experiment was set up using a Completely Randomized Design (CRD) with 6 treatments namely A0 (control), A1 (chicken manure), A2 (goat-manure, A3 (buffalo manure), A4 (horse manure), and A5 (cattle manure) which were repeated 3 times. The results showed that application of manures significantly affect fresh weight of stover, the dry weight of stover, N and P uptake. The application of buffalo manure tend to have the highest nutrients uptake.
