Abstract

ABSTRACT One of the harmful insects in maize is the wanderer Grasshopper (Locusta migratoria L.). Grasshopper wanderer often found the area under maize cultivation . Grasshopper wanderer, both young (nymphs) and old, eating the leaves of corn plants, thereby reducing the surface area of leaves. Adult grasshoppers usually eat the leaf edges , while his nymph takes in between bones , causing leaves holes in the leaves. If this locust attack in a high number of population, the leaves of corn plants that are attacked will be devoured. In connection with the matter, has done research on  grasshopper  population  density  wanderer  on  corn  in  the  Village  Banana  Padang  Pauh subdistrict which aims to determine the wanderer grasshopper population densities on corn plants in Padang Pauh subdistrict Banana Village. This study was conducted in September-October 2013, with the method sweep (sweeping) is a way to swing a grasshopper inseknet existing wanderer on corn which is used as a place of research. Field sampling conducted on maize age of 1 month and2 months after planting by using inseknet and hands. Widely used as a research area of 20x20 m. Sampling was conducted at five points with a size of 3x3 m at each point. Physical environmental factors measured are temperature and humidity. From the research that has been conducted in the village of Padang Pauh subdistrict Bananas can be concluded that the grasshopper population density wanderer in maize of different ages 1 month to 2 months of age. Wanderer grasshopper populations on corn gained as much as 1 month of age 0.7 individuals/m² (0.3 nymphs and 0.4 imago), population density is lower than in maize aged 2 months gained as much as 1.8 individuals/m² (0,7 nymphs and 1.1 imago). Grasshopper population density wanderer found already included in the criteria pests.

Abstract

Rifampisin merupakan salah satu terapi lini pertama dari tuberkulosis. Peningkatan kasus tuberkulosis setiap tahun menyebabkan penggunaan rifampisin juga sangat tinggi. Penggunaan rifampisin yang berlebihan menyebabkan efek samping berupa kerusakan ginjal. Kerusakan pada ginjal tersebut dapat diatasi dengan senyawa antioksidan. Salah satu antioksidan yang dapat digunakan adalah thymoquinone. Penelitian ini bertujuan untuk mengetahui apakah thymoquinone dapat memberikan efek protektif terhadap gambaran histopatologi ginjal tikus putih (Rattus novergicus) galur Sprague dawley yang diinduksi rifampisin. Penelitian ini merupakan penelitian ekperimental menggunakan 25 ekor tikus putih galur Sprague dawley yang dibagi ke dalam 5 kelompok, yaitu kontrol 1 (K1) tikus yang tidak diberikan perlakuan, kontrol 2 (K2) diberikan rifampisin dosis 100 mg/100gBB serta P1, P2 dan P3 diberikan rifampisin 100 mg/100gBB dan thymoquinone dengan dosis berbeda yaitu 5 mg/kgBB, 10 mg/kgBB dan 20 mg/kgBB dalam waktu 14 hari. Hasil penelitian menunjukan bahwa rerata skor kerusakan ginjal pada K1: 1,28, K2: 3,16, P1: 2,08, P2: 2,12, P3: 2,88. Data yang diperoleh, diuji dengan u j i Kruskal-Wallis, didapatkan perbedaan bermakna p= 0,02 (p<0,05). Terdapat efek protektif thymoquinone terhadap gambaran histopatologi ginjal tikus putih (Rattus novergicus) galur Sprague dawley yang diinduksi rifampisin.Kata kunci: histopatologi ginjal, rifampisin, thymoquinone.
