Peanut has high economic value because has high nutritions especially protein and fat, but the development of broad harvesting and peanut production for the last five years (2008-2012) continues to decrease. The main problem of the peanut low production are disease attacks S. rolfsii and the low broad harvesting. The drop of peanut production in Nusa Tenggara Barat causing harm caused by fungi S.rolfsii can reach 58,3 % per year. Peat is potential land to be developed to farming land. Peat has high acidity so fungi S. rolfsii would be easy to develop and resulted disease severity of peanut disease. Solution of this problem is the gift of lime. This study aims (1) to test the effect of dosages of lime to peanut resistance which was infected by rot stem S. rolfsii on peat land; (2) to study interaction of peanut varieties and dosage of lime to rot stem disease attacks S. rolfsii on peat land. This study used factorial block randomized design 2 x 3 with 3 replications. The studied factors were peanut varieties and the dosage of lime. The result showed that on the effect of varieties, the widest disease percentage was on Takar 2 variety on age 21, 28, 42, and 49 day after planting (DAP) that significant difference with Bison variety. The worth disease intensity was on Takar 2 variety that significant difference with Bison variety (on age 45 and 60 DAP). Key words: dosage of lime, peanut varieties, peat land, the sclerotia of Sclerotium rolfsii

Research on the effect of concentration and frequency of giving PKS liquid waste on the growth and yield of mustard (Brassica juncea L.) was conducted in Arongan Village, Kuala Pesisir District, Nagan Raya Regency starting from November to December 2021. The design used was a randomized block design (RAK) factorial. The first factor is the concentration of PKS liquid waste which consists of 3 treatment levels K1 (4%), K2 (8%), and K3 concentration of PKS liquid waste 12%). The second factor is the frequency of watering PKS liquid waste which consists of 3 levels of treatment P1(frequency of watering PKS liquid waste 5 days 1 time), P2 (frequency of watering PKS liquid waste 7 days 1 time), and P3 (frequency of watering PKS liquid waste 9 days). 1 time). The results of the study did not show an interaction between the treatment of PKS liquid waste concentration and the frequency of watering PKS liquid waste with all observed variables. The concentration of PKS liquid waste had a significant effect on the number of leaves at 29 DAP and root length. Varieties treatment did not have a significant effect on all observed variables. Keywords: concentration, frequency, PKS liquid waste, mustard plant

<p>Kehilangan brondolan kelapa sawit atau <em>losses</em> yang berhubungan langsung dengan hilangnya berat TBS (Tandan Buah Segar) merupakan suatu bentuk kerugian bagi perusahaan perkebunan kelapa sawit. Tujuan penelitian ini adalah untuk 1) mengetahui besarnya <em>losses </em>brondolan kelapa sawit di areal datar dan berbukit; 2) mengidentifikasi faktor penyebab <em>losses</em> brondolan kelapa sawit; dan 3) mengetahui teknis penanganan <em>losses </em>brondolan kelapa sawit. Penelitian ini dilaksanakan di perkebunan kelapa sawit Kebun Tanoh Makmue PT. Agro Sinergi Nusantara (PT. ASN) Kecamatan Woyla Barat, Kabupaten Aceh Barat, Provinsi Aceh pada bulan Oktober 2021 hingga Februari 2022. Penelitian ini menggunakan metode survey deskriptif kuantitatif. Lokasi lahan perkebunan yang dijadikan sampel ditetapkan dengan metode <em>stratified sampling.</em> Penelitian ini dilakukan pada Afdeling 2 dengan blok 12 BB untuk areal berbukit dan blok 13 BB untuk areal datar. Pengambilan data dilakukan dengan metode Sensus Kerapatan Buah Semester (SKBS) serta observasi langsung. Hasil penelitian menunjukkan bahwa 1) <em>losses</em> brondolan terbanyak ditemukan pada piringan dan pelepah kelapa sawit areal berbukit yaitu sebesar 2.272 buah brondolan dan 1.206 buah brondolan untuk areal datar<em>; 2) </em>faktor penyebab <em>losses</em> yaitu kondisi lahan, kondisi tanaman, tenaga kerja dan SOP, 3) teknis penanganan <em>losses</em> berupa perbaikan lahan, pemeliharaan tanaman dan peningkatan SDM tenaga kerja serta SOP.</p><p><strong><em>Kata kunci:</em></strong><em> losses, brondolan kelapa sawit, areal berbukit, areal datar</em></p>
