Penggunaan pestisida cukup tinggi dan berlebihan, disinyalir telah mencemari lahan bawang merah di Kabupaten Brebes. Dampak negatif  penggunaan pestisida sudah dirasakan oleh petani, namun perilaku dan tata cara penggunaan pestisida belum banyak berubah. Sekolah lapang pengendalian hama terpadu telah dilaksanakan dan subsidi pestisida juga sudah dicabut, namun kenyataan di lapangan penggunaan pestisida terus meningkat. Residu pestisida yang terakumulasi di lahan pertanian diyakini sebagai penyebab menurunnya tingkat kesuburan tanah. Akibat dari penggunaan pestisida yang berlebih perlu dilakukan pengendalian pencemaran lingkungan sebagai wujud program keamanan pangan nasional. Sebelum dilakukan pengendalian perlu dilakukan identifikasi cemaran. Tujuan penelitian adalah untuk mengidentifikasi cemaran profenofos yang yang ada di lahan bawang merah Kabupaten Brebes. Penelitian dilaksanakan di lapang dan laboratorium. Penelitian lapang dilaksanakan di Kabupaten Brebes Jawa Tengah dan analisa residu pestisida dilakukan di laboratorium terpadu  Balai Penelitian Lingkungan Pertanian (Balingtan). Kegiatan ini berlangsung dari bulan Februari hingga April 2018. Metode yang dilakukan adalah metode survey dan wawancara petani dalam pengambilan sampel di lapang. Sampel tanah diambil dari 18 titik sampling yang berlokasi di 8 Kecamatan di Kabupaten Brebes. Dalam 1 titik sampel diambil secara komposit dari 5 titik sampling. Sampel tanah dilahan  bawang merah yang diperoleh dari lapangan masing-masing diuji residu insektisida profenofos menggunakan metode Quecher. Hasil penelitian menunjukkan dari 18 titik sampel tanah yang diambil, terdeteksi cemaran insektisida profenofos sebanyak 17 sampel  (94,44%) dengan konsentrasi <LOD – 0,510 ppm dengan BMR 0,30 ppm.

Chlorpyrifos is a broad-spectrum insecticide and is widely used to Organism Pests Management (OPM). The remediation technology for polluted land is needed to reduce the risk of continuous impacts. The research aimed to reduce chlorpyrifos insecticide residues in shallot agriculture through remediation technology. The research was carried out in Naru Village, Sape Sub-District, Bima Regency (NTB) in June-August 2018. The experiment was designed in a randomized block design (RBD), three replications, and six treatments: (T1) farmers method, (T2) urea fertilizer-coated biochar, (T3) urea fertilizer-coated biochar enriched with consortia microbes, (T4) consortium microbes 2 L ha−1, (T5) urea fertilizer-coated nano biochar, and (T6) urea fertilizer-coated nano biochar enriched with consortia microbes. Remediation agents containing carbon, such as biochar and manure and some microbes can help accelerate the degradation of insecticides in the environment. Decreased chlorpyrifos residue from highest to low, respectively: urea fertilizer coated nano biochar>urea fertilizer coated nano biochar with enriched consortium microbes>urea fertilizer coated biochar>urea fertilizer coated biochar with enriched consortium microbes>consortium microbes 2 L ha−1. Treatment of urea fertilizer coated nano biochar and urea fertilizer coated nano biochar with enriched consortium microbes can be applied as a chlorpyrifos remediation technology in the shallot agriculture in silt texture soils.

This research aims to understand the extent of the students’ participation to join the lectures during the Covid-19 pandemic, that requires the lectures to be conducted through online system. In such a condition Inquary-based learning is selected as an appropriate method of learning, in which the students’ independence is needed. The researchers conducted a case study on the application of inquiry-based learning, especially in the subject of Structure-Grammar, at the English Study Program, Academy of Foreign Language St. Pignatelli Surakarta In the implementation of this method the students are expected to be autonomous learners who must be aware of themselves that they need particular knowledge and consequently, with their own accord they will find any sources from both reference-books and scientific webs. The role of the lecturer is to guide them in such a way that they master the minimum requirements. The research results show that the students of Semester II give 66.66% of positive response, and those of Semester IV 73.55%. There are more than 25 % of students who do not give positive participation to the lectures due to  several obstacles, namely the lack of smart phones, adequate computers or internet access. Although the results are not so satisfying, they can be used as a reference for autonomous learning.
