Tujuan penelitian untuk mengkaji pengaruh aplikasi kompos dan asam humat terhadap produktivitas tanah pasir serta pertumbuhan dan produktivitas sawi hijau. Penelitian dilakukan secara eksperimental di greenhouse dengan menumbuhkan semai sawi hijau pada tanah pasir yang diberi perlakuan aplikasi pembenah tanah. Terdapat tiga perlakuan yaitu kontrol (P0), aplikasi kompos (P1), dan aplikasi asam humat (P2). Parameter produktivitas pasir yang diukur meliputi: deskripsi konsistensi struktur tanah dan kandungan air kapasitas lapang. Dilakukan pengukuran terhadap persentase peningkatan jumlah akar, panjang akar lateral, bobot kering akar, jumlah daun, luas daun, bobot kering daun dan kandungan pigmen fotosintesis (klorofil a, klorofil b dan karotenoid) untuk mengetahui respon pertumbuhan dan produktivitas tanaman. Hasil penelitian menunjukkan terdapat perubahan struktur tanah pasir dari struktur lepas menjadi gembur dan lekat setelah aplikasi kompos, dan teguh setelah aplikasi asam humat. Aplikasi kompos dan asam humat menyebabkan peningkatan persentase kadar air kapasitas lapang. Persentase kadar air tanah P1 (52,6%) lebih tinggi dibanding P2 (10,7%) dan P0 (6,4%). Persentase pertumbuhan dan produktivitas tanaman sawi tertinggi terdapat pada P1 diikuti P2 dan P0 yaitu: 3,2%, 2,3%, 1,8% (panjang akar lateral), 59,4%, 47,2%, 33% (bobot kering akar), 21%, 19,6%, 14,5% (luas daun), 28,4%, 24,9%, 24% (bobot kering daun). Penurunan luas daun pada P2 dan P0 diimbangi dengan peningkatan kandungan pigmen fotosintesis untuk optimalisasi penyerapan cahaya. Secara umum aplikasi kompos dan asam humat dapat memperbaiki struktur tanah pasir. Aplikasi kompos lebih efektif meningkatkan retensi air dan pertumbuhan serta produktivitas tanaman herbaceous sawi hijau pada tanah pasir. Sandy soil is inherently infertile and has low water and nutrient retention capabilities. This study aims to evaluate the impact of compost and humic acid application on the productivity of sandy soil and the growth and productivity of mustard plants. The research was conducted experimentally in a greenhouse, where mustard seedlings were grown in sandy soil treated with soil amendments. Three treatments were employed: control (P0), compost application (P1), and humic acid application (P2). Soil productivity parameters measured included soil structure consistency and field capacity water content. Growth and productivity responses of the plants were assessed by measuring the percentage increase in root mass, lateral root length, root dry weight, number of leaves, leaf area, leaf dry weight, and photosynthetic pigment content (chlorophyll a, chlorophyll b, and carotenoids). Results indicated that the soil structure of sandy soil changed from loose to crumbly and cohesive after compost application and to firm after humic acid application. Both compost and humic acid applications led to increased field capacity water content, ","PeriodicalId":481145,"journal":{"name":"Buletin anatomi dan fisiologi","volume":"34 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141268961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tikus putih yang digunakan adalah tikus jantan galur Wistar dengan umur 2 bulan dan berat badan rata-rata kurang lebih 200g. Hewan uji dibagi menjadi 6 kelompok perlakuan dengan 5 ulangan yaitu: Kontrol negatif (P0) diberi ransum komersial; kontrol positif (P1: diberi ransum tinggi lemak); pengobatan P2 (P1+ simvastatin 8mg/g BB); dan P1+ dosis ekstrak etanol biji mahoni sebesar 70;140;280 mg/kg BB(P3;P4 dan P5). Variabel yang diamati adalah kadar kolesterol total, HDL, LDL dan TG. Analisis data menggunakan ANOVA dilanjutkan dengan uji Beda Nyata Terkecil (BNT) dengan tingkat kepercayaan 95% menggunakan software SPSS 10.0.

Mahogany seeds contain flavonoids which have the ability as hypoglycemic agents. This study aimed to analyze the effect of mahogany seed ethanol extract as an antihyperlipidemic herb in white rats induced by high-fat rations. The white rats used were male Wistar strain rats with the age of 2 months and the average BW of approximately 200g. The test animals were divided into 6 treatment groups with 5 replications, namely: Negative control (P0) was given a commercial ration; positive control (P1: given high-fat ration); P2 treatment (P1+ simvastatin 8mg/g BW); and P1+ the dose of ethanol extract of mahogany seeds of 70;140;280 mg/kg BW(P3;P4 and P5). The variables observed were total cholesterol, HDL, LDL and TG levels. Data analysis using ANOVA was followed by the Least Significant Difference (BNT) test with a 95% confidence level using SPSS 10.0 software.
