Penelitian ini bertujuan mengkaji sistem tata kelola air pada lahan gambut dan pengaruhnya terhadap produksi Kelapa Sawit. Kajian ini dilaksanakan di PT. Uni Primacom Desa Barunang Miri, Kecamatan Parenggean, Kabupaten Kotawaringin Timur, Provinsi Kalimantan Tengah pada bulan Juli sampai dengan Oktober 2020. Metoda penelitian yang digunakan adalah metode survey yang terdiri dari dua tahap yaitu tahap pertama Survey Pendahuluan dan tahap kedua adalah Survey Utama. Survey pendahuluan dilakukan untuk menentukan tempat penelitian dan sampel tanaman. Survey utama dilakukan untuk pengambilan data baik data primer maupun data sekunder. Data yang diperoleh dianalisis dengan menggunakan Regresi Korelasi dalam 2 tipe yaitu Regresi Linier sederhana dan Regresi polinomial sederhana. Data yang dibutuhkan adalah data primer yang meliputi : a) pengamatan tingkat kematangan gambut dan b) kedalaman gambut, sedangkan data sekunder yang dibutuhkan adalah : a) water table (th 2015 – 2018), b) curah hujan bulanan (th 2011 - 2020), c) hari hujan (th 2011 - 2020), d) produksi kelapa sawit (ton/ha) (th 2015 - 2018). Hasil penelitan menunjukkan bahwa tidak ada korelasi antara curah hujan dengan tinggi muka air tanah (Water Table) dengan persamaan Regresi yang dipilih adalah Regresi linier sederhana dengan persamaan Y= 48,629 - 0,0612 X dengan koefisien korelasi (R˄2) adalah 0,331 artinya persamaan Regresi diatas menunjukkan semakin tinggi X (curah hujan) maka semakin rendah Y (Water Table), dan tidak ada hubungan yang erat antara curah hujan dengan tinggi muka air (Water table). Untuk hubungan antara curah hujan dengan produksi pun juga diperoleh hubungan yang tidak erat dengan nilai koefisien korelasi (R˄2) 0,4017 dengan persamaan Regresi Linier sederhana yaitu Y = 17,319 + 0,0465 X, artinya semakin tinggi X (curah hujan) maka semakin tinggi Y (produksi kelapa sawit. Sedangkan hubungan antara tinggi muka air tanah (Water Table) dengan produksi Kelapa sawit diperoleh persamaan regresi Linier sederhana dengan persamaan Y = 48,678 - 0,601 X dan nilai koefisien korelasi nya (R˄2) = 0,759. Hal ini menunjukkan bahwa ada hubungan yang erat antara water table dengan produksi kelapa sawit, semakin tinggi (semakin dalam) X (water table) maka produksi kelapa sawit semakin (Y) semakin rendah. Dari hasil analisis tersebut maka dapat diambil kesimpulan bahwa pengelolaan air di areal gambut pada PT UNI PRIMACOM, Desa Barunang Miri, Kecamatan Parenggean, Kabupaten Kotawaringin Timur, Kalimantan Tengah sudah bagus, yang ditunjukkan oleh tidak adanya hubungan yang erat antara curah hujan dengan tinggi muka air, dan curah hujan dengan produksi, tetapi produksi kelapa sawit justru dipengaruhi oleh tinggi muka air tanah (Water Table) yang ada campur tangan management.

Pengaruh cekaman kekeringan akibat perubahan iklim memerlukan suatu upaya untuk menjaga ketahanan tanaman dengan cara pemberian pupuk silika (Si) yang dikombinasikan dengan pupuk NPK. Penelitian ini bertujuan untuk mengetahui pengaruh pupuk NPK dan pupuk silika terhadap pertumbuhan bibit kelapa sawit. Penelitian ini dilaksanakan pada bulan Desember 2019 sampai dengan Mei 2020, bertempat di desa Maguwoharjo, Kecamatan Depok, Kabupaten Sleman, Yogyakarta dan Laboratorium Sentral, Institut Pertanian Stiper, Yogyakarta. Penelitian ini merupakan percobaan faktorial yang disusun dalam Rancangan Acak Lengkap (Completely Randomized Design). Faktor pertama adalah pupuk NPK (16-16-16) yang terdiri dari tiga aras yaitu, tanpa pupuk NPK, pupuk NPK (2,5 g/bibit), pupuk NPK (5 g/bibit). Faktor kedua adalah pupuk silika (SiO2) yang terdiri dari empat aras yaitu, tanpa pupuk silika, pupuk silika 5% (10 ml/bibit), dan pupuk silika 10% (20 ml/bibit), pupuk silika 15% (30 ml/bibit). Setiap perlakuan dilakukan 5 kali ulangan sehingga jumlah bibit kelapa sawit keseluruhan adalah 60 bibit. Hasil penelitian dianalisis dengan menggunakan metode Analysis of Variance (Anova) pada jenjang nyata 5% dan untuk mengetahui beda nyata antar perlakuan diuji dengan uji Duncan’s Multiple Range Test (DMRT) pada jenjang nyata 5%. Hasil penelitian menunjukan tidak adanya interaksi nyata antara pupuk NPK dan pupuk silika terhadap pertumbuhan bibit kelapa sawit. Pemberian pupuk NPK dengan berbagai dosis dan pupuk silika dengan berbagai konsentrasi memberikan pengaruh yang sama terhadap seluruh parameter yang diamati, akan tetapi dosis 2,5 g/bibit dan konsentrasi 10% memberikan nilai rata-rata tertinggi hampir di semua parameter pengamatan.

The aims of this research are to determine the best medium to propagation entomopathogenic fungi C. militaris, to determine effectivity and dosage of C. militaris to control pupae of S. asigna. This research was conducted in plantation of PT. Satya Kisma Usaha Unit Batang Gading, Tanah Tumbuh County, Muara Bungo District, Jambi. The research was conducted from August to September 2020. This study used a non-factorial method, which was arranged in a completely randomizing design (CRD) with 1 factor, namely growth media. The growth media are consisted of corn seeds (M1) and bran (M2) and repeated 5 times. For dosage of fungi used a non-factorial method, which was arranged in a CRD with 1 factor, namely bran media. The bran media dosages are P0 = control (100 ml aquadest/polybag), P1 = 10 g C. militaris + 100 ml aquadest/polybag, P2 = 20 g C. militaris + 100 ml aquadest/polybag, P3 = 30 g C. militaris + 100 ml aquadest/polybag P4 = 40 g C. militaris + 100 ml aquadest/polybag and all of them are repeated 4 times. The results showed that bran medium is the best medium for fungi propagation. C. militaris was effectively to control pupae of S. asigna. The best of fungi dosage is P4 = 40 g C. militaris + 100 ml aquadest/polybag. The highest pupae mortality (100%) is achieved at 12 days observation.

Oryctes rhinoceros (Coleoptera: Scarabidae) atau dikenal sebagai kumbang tanduk merupakan hama yang cukup penting di perkebunan kelapa sawit, terutama bila menyerang tanaman belum menghasilkan. Penelitian bertujuan untuk mengkaji keefektifan orynet trap terhadap hasil tangkapan kumbang tanduk, serta pengaruhnya terhadap intensitas kerusakan. Penelitian dilaksanakan dengan membandingkan perangkap feromon + jaring (Orynet trap) dengan feromon+insektisida polidor. Hasil penelitian menunjukkan jumlah O. rhinoceros yang tertangkap pada perlakuan feromon+perangkap jaring (orynet trap) lebih banyak daripada feromon+insektisida polidor. Tidak terjadi penambahan intensitas kerusakan tanaman setelah perlakuan feromon+jaring (Orynet trap), sebaliknya intensitas kerusakan tanaman meningkat sebesar 11,9 – 18,8% pada perlakuan feromon+insektisida polydor. Diharapkan, penelitian ini akan bermanfaat sebagai salah satu alternatif untuk pengendalian O. rhinoceros di perkebunan kelapa sawit. Kata kunci : Kelapa Sawit, O. rhinoceros, Orynet Trap
