Gulma merupakan tumbuhan yang tidak dikenhendaki keberadaannya. Keberadaan gulma disekitar tanaman budidaya dapat menimbulkan kerugian baik dari segi kualitas maupun kuantitas. Tumbuhan gulma memiliki senyawa alelopati yang dikeluarkan melalui organ yang berada diatas maupun yang berada dibawah tanah. Pelepasan senyawa tersebut dapat terjadi melalui penguapan, eksudat akar, pencucian, dan pembusukan bagian bagian yang mati. Salah satu alternative usah dalam pengendalian gulma yang ramah lingkungan adalah dengan menggunakan bioherbisida alami. Penelitian ini bertujuan untuk menguji potensi bioherbisida ekstrak daun mahoni(Swietenia mahagoni (L). (Jack) terhadap pertumbuhan gulma babandotan (Ageratum conizoides L.). Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 5 perlakuan 0%, 30%, 40%, 50%, 60% dengan 3 ulangan. Parameter pada penelitian ini adalah tinggi gulma, jumlah helai daun, bobot segar, bobot kering, warna daun gulma. Hasil penelitian menunjukkan dengan konsentrasi 40% efektif menghambat pertumbuhan tinggi gulma babandotan, sedangkan pada konsentrasi 60% dapat menghambat pertumbuhan daun, bobot segar dan bobot kering pada gulma babandotan. Semakin tinggi konsentrasi yang digunakan maka semakin efektif ekstrak daun mahoni menghambat pertumbuhan gulma babandotan. Ekstrak daun mahoni belum mempengaruhi warna daun dari gulma babandotan.

Air merupakan kebutuhan manusia yang paling penting. Jumlah air yang terdapat pada tubuh manusia mencapai 68% dan untuk tetap hidup kadar air dalam tubuh harus dipertahankan. Kebutuhan air minum setiap orang bervariasi mulai dari 2,1 liter hingga 2,8 liter perhari. Semakin hari jumlah penduduk semakin bertambah, begitu juga dengan keubutuhan air, termasuk air minum. Pertumbuhan penduduk yang semakin padat menyebabkan rendahnya kemampuan tanah untuk menyerap air karena perubahan tata guna tanah yang tidak terkendali sebagai dampak kepadatan penduduk. Air minum yang sehat dan aman untuk dikonsumsi harus memenuhi persyaratan yang meliputi syarat fisik, kimia dan bakteriologis. Syarat fisik kualitas air minum meliputi warna, rasa, kekeruhan dan bau. Syarat kimia kualitas air minum dengan melihat keberadaan senyawa yang membahayakan yaitu timbal, tembaga, raksa, perak, kobalt, sedangkan syarat bakteriologis kualitas air minum ini dapat dilihat dari ada tidaknya bakteri coliform pada Air. Air minum harus aman diminum yang artinya bebas mikroba patogen dan zat berbahaya dan diterima dari segi warna, rasa, bau dan kekeruhannya .Syarat bakteriologis air minum menurut peraturan Menteri Kesehatan Republik Indonesia Nomor 492/Menkes/SK/IV/2010 adalah air minum tidak boleh mengandung bakteri patogen. Bakteri patogen adalah bakteri yang dapat menyebabkan penyakit terutama penyakit saluran pencernaan. Salah satunya yaitu bakteri coliform. Sehingga perlu diadakan peneltian mengenai kemungkinan cemaran mikroorganisme pathogen pada air minum isi ulang tersebut. Keberadaan bakteri Coliform tertinggi di temukan pada sample ST2 dengan 2,3 x 104 , sedangkan Keberadaan bakteri Coliform terendah pada sample ST1 dengan 1,3 x 103 Departemen kesehatan R.I. 2004 angka tersebut tidak berbahaya bagi kesehatan, karena masih dibawah total koloni maksimum yaitu 5 x 105 cfu/ml.

Riau Province has the largest oil palm plantation area in Indonesia, reaching 2,594,227 ha. One of the main challenges in oil palm cultivation is to increase seedling productivity through the provision of optimal nutrients. This study aims to evaluate the effect of goat biourine as liquid organic fertilizer on the growth of oil palm seedlings (Elaeis guineensis Jacq.) in the main nursery and determine the best biourine concentration. The research was conducted in a completely randomized design (CRD) consisting of five treatments of goat biourine concentration (0, 200, 300, 400, and 500 ml/liter of water) with three replications, resulting in 15 experimental units. The observed variables included biourine nutrient content analysis, seedling height, midrib length, midrib number, and culm diameter. The results showed that the application of goat biourine had a significant effect on midrib length at a concentration of 400 ml/liter of water, but had no significant effect on seedling height, number of midribs, and cob diameter. Goat biourine is proven as an alternative organic fertilizer that can support the growth of oil palm seedlings, but further research is needed to explore the optimal dose and higher nutrient content, especially nitrogen, to increase efficacy.

RIZKI HANDAYANI, NIM 1827028. "The Effect of Giving Rice Husk Charcoal on the Growth and Production of Shallot Plants (Allium ascolanicum. L)". Supervised by Lufita Nur Alfiah, SP., M.Si and Rizah Rizwana Wahyuni, S.TP., M.Sc.Onion (Allium ascalonicum L) is a horticultural plant belonging to the vegetable and spice group as a food flavoring. Shallots are one of the leading vegetable commodities that have been intensively cultivated by farmers for a long time. Acidic soil is soil that has a low pH, generally acidic soil will reduce the level of land productivity for some plants. Soil conditions with low productivity levels require the addition of ameliorant. The ameliorant that can be used is rice husk charcoal. Rice husk charcoal can be used to improve the place where a plant grows and can function as a builder of soil fertility. This research was conducted to determine the effect of giving various doses of rice husk charcoal on the growth and production of shallot plants. This research was carried out at the Kassa House of the Faculty of Agriculture, Pasir Pengaraian University from May to August 2022. The design used in the study was a Completely Randomized Design (CRD) with 5 treatments, namely R0 = 0 g/polybag, R1 = 20 g/polybag , R2 = 40 g/polybag, R3 = 60 g/polybag, and R4 = 80 g/polybag. The results showed that the results were not significantly different with the administration of several doses of rice husk charcoal on all observation parameters. Parameters of plant height and fresh weight of tubers tended to be higher by administering a dose of rice husk charcoal 80 g/polybag. While administration at a dose of 40 g/polybag tends to be higher for the number of tubers planted compared to other doses.
