Laser inframerah sering diaplikasikan pada tanaman, salah satunya pada tanaman padi. Padi (Oryza sativa L.) merupakan tanaman yang hasil panennya menjanjikan untuk masyarakat Indonesia, namun tidak semua padi dapat dipanen dan tidak semuanya dapat dipasarkan. Karakteristik padi yang baik untuk dipasarkan dan dikonsumsi terdapat pada tinggi dan jumlah anakan produktif tanaman padi sesuai dengan perlakuan tertentu. Tujuan penelitian ini adalah menganalisis pengaruh laser inframerah terhadap tinggi dan jumlah anakan produktif tanaman padi. Penelitian ini dilakukan pada sawah seluas 5 m2 di Desa Ngoran, Kecamatan Nglegok, Kabupaten Blitar. Tanaman padi pada penelitian ini berjenis Inpari 13 yang berumur 48 hari setelah sebar (HSS). Karakteristik data panjang gelombang infrared memiliki rata-rata sebesar 497,53 micrometer serta pada data tinggi batang padi memiliki rata-rata sebesar 56,845 cm. Pola hubungan antara panjang gelombang infrared dengan tinggi batang padi menunjukkan korelasi yang positif. Artinya, jika panjang gelombang infrared bertambah maka tinggi batang padi akan bertambah. Jika panjang gelombang infrared bernilai 0 maka tinggi batang padi sebesar 55,226 cm, dan jika panjang gelombang infrared naik 1 satuan maka tinggi batang padi akan naik sebesar 0,03. Pengujian asumsi residual IIDN residual data tinggi batang padi memenuhi asumsi identik, independen, dan berdistribusi normal.
The fulfillment of human daily needs cannot be separated from water. The water most used by the community is ground water. One of the factors that can affect water quality is the depth of the water source. The purpose of this study was to analyze the effect of soil height and well depth on the temperature and pH of well water in Blitar Regency. The data was taken from 4 sub-districts in Blitar Regency, namely Ponggok, Nglegok Kesamben, and Selorejo. The characteristics of the pH of the water have an average of 6.7 and a water temperature of 23.43⁰C. If the depth of the well is increased by 1 meter, the pH of the water will increase by 0.1177 units. If the depth of the well is increased by 1 meter, the water temperature will increase by 0.126⁰C. Based on the results of the simultaneous test, it is known that the depth of the well and the height of the soil have a significant effect on water pH and water temperature. Based on the results of the partial test, it is known that the depth of the well has no significant effect on water pH and water temperature. However, the height of the soil has a significant effect on water pH and water temperature. Based on the results of the model goodness test, it can be seen that the proportion of water pH variability can be explained by the variable depth of the well and the height of the soil by 36.03% and the remaining 63.97% is influenced by other variables outside the model and the proportion of water temperature variability can be explained by the variable depth of the well and the ground height is 92.58% and the remaining 7.42% is influenced by other variables outside the model.
Sand and stone mining activities along the Berni River in Sumberasri Village, Nglegok District, Blitar Regency are still ongoing, so that the impact on the community is increasingly being felt. The real impact felt by the community is landslides and erosion. The purpose of this study was to analyze the community's response to the impact of sand and rock mining activities in the Berni River, Sumberasri Village, Nglegok District, Blitar Regency. The method used is a survey by conducting interviews with 40 residents who live around the Berni River, Sumberasri Village, Nglegok District, Blitar Regency. Based on the data analysis that has been carried out and explained, most of the people living around the mining area are not disturbed by mining activities because sand and rock mining is their main livelihood. There are 80% of people living in mining areas who admit that mining activities do not interfere with their activities, 90% of people who live in mining areas admit that their health is not disturbed, and 80% of people who live in mining areas admit that they have benefited from sand and rock mining activities. the. However, they all realized that the mining of sand and rock was causing losses, namely that more roads were damaged and erosion and landslides were frequent. Keywords: Mine, Sand and Stone. ABSTRAKAktivitas penambangan pasir dan batu di sepanjang Sungai Berni di Desa Sumberasri, Kecamatan Nglegok, Kabupaten Blitar masih berlangsung sampai saat ini, sehingga dampak di masyarakat semakin dirasakan. Dampak nyata yang dirasakan masyarakat adalah longsor dan erosi. Tujuan dari penelitian ini adalah untuk menganalisis respon masyarakat terhadap dampak aktivitas penambangan pasir dan batu di Sungai Berni, Desa Sumberasri, Kecamatan Nglegok, Kabupaten Blitar. Metode yang digunakan adalah survei dengan melakukan wawancara terhadap 40 warga yang tinggal di sekitar Sungai Berni, Desa Sumberasri, Kecamatan Nglegok, Kabupaten Blitar. Berdasarkan analisis data yang telah dilakukan dan dijelaskan, sebagian besar masyarakat yang tinggal di sekitar area pertambangan tidak mendapat gangguan akibat aktivitas penambangan karena penambangan pasir dan batu tersebut merupakan mata pencaharian utama mereka. Terdapat 80% masyarakat yang tinggal di area pertambangan mengakui bahwa aktivitas penambangan tidak mengganggu aktivitas mereka, 90% masyarakat yang tinggal di area pertambangan mengakui bahwa kesehatan tidak terganggu, dan 80% masyarakat yang tinggal di area pertambangan mengaku mendapat manfaat dari kegiatan penambangan pasir dan batu tersebut. Namun, mereka semua menyadari bahwa penambangan pasir dan batu tersebut menyebabkan kerugian, yaitu semakin banyak jalan yang rusak serta sering terjadi erosi dan longsor. Kata kunci: Tambang, Pasir dan Batu.
The purpose of this study was to analyze the quality of river water based on differences in height, namely in rivers with an altitude of ± 349 in Nglegok District and rivers with an altitude of ± 252 in Kademangan District, Blitar Regency. Measurement of river water brightness using Sechhi Disk. Measurement of temperature, pH and TDS is carried out by measuring river water samples taken. Based on the data analysis that has been carried out and explained, the quality of river water will be inversely proportional to the temperature and TDS value. Meanwhile, the quality of river water is directly proportional to the brightness and pH. The water temperature in the Bladak River is cooler or lower than the water temperature in the Kedungrawis River. The water in the Bladak River is brighter than the water in the Kedungrawis River. The pH of the water in the Bladak River is higher or more alkaline than the pH of the water in the Kedungrawis River. The Total Dissolved Solid (TDS) value in the Bladak River is smaller than the TDS value in the Kedungrawis River
