<p><em>Expansion of agricultural land is needed to accomplish the future national food demand. Expansion of agricultural land has been focused on marginal land such as peatland</em><em>. </em><em>The studies was carried out at IAERI experimental farm and used 12 microplots with each have a dimension of 1,5 m x 1,5 m x 1 m and was filled with peat from South Kalimantan. Amelioration treatments such as dolomite (Ca-rock), volcanic ash, peat fertilizer, Fe fertilizer, nitrification inhibitor and control were established as treatments to the microplots, after amelioration, the plots was planted by Inpara 2 rice cultivar. Data of the result was analyzed by Analysis of Variance (ANOVA) and Duncant Multiple Range Test (DMRT). The result showed that the highest net carbon from non ameliorant (control) and the lowest from volcanic ash. </em><em>Net carbon highet at non ameliorant (control) </em><em>3785 </em><em>kg-C/ha followed dolomite, Fe fertilizer, NI (nitrification inhibitor), </em><em>peatland fertilizer</em><em> and volcanic ash i.e 3238; 2082; 1574; 1439 and -712 kg-C/ha</em><strong><em></em></strong></p>

Inputs are the absolute requirement in the process of production, if the one of production factor is not fulfilled then the process of production will not running smoothly in other words will not maximize. The purposes of this study were to know the influence of land size, capital, and labor to the production of wetland paddy in Binalawan Village West Sebatik Subdistrict. This study was held from September to November 2017. Sampling method in this study was simple random sampling with total of 32 farmers as respondents. Data analysis used  multiple linear regression. The result of t test showed that the land size, capital, and labor do not influence  the decrease of wetland paddy production, it was showed from the value of tcount  (1.518) < ttable (2.048). The land size, capital, and labor influence the production of wetland paddy, this was showed from the value of Fcount (3.557) > Ftable (2.930). R shows that there are relation between land size, capital, and labor to the production of wetland paddy, Rcount (0.526) with significant value was 0.026 shows there are relation or middle correlation between land size, caapital, and labor to the production of wetland paddy in Binalawan Village.

Keragaan morfologi dan kandungan antosianin padi beras merah (Oryza sativa L.) pada Kecamatan Munte dan Kecamatan Payung di Kabupaten Karo. Penelitian ini bertujuan untuk mendapatkan informasi morfologi dan kandungan antosianin padi beras merah (Oryza sativa L.). Penelitian ini dimulai dari Juni 2017dan selesai pada Januari 2018 di kecamatan Munte dan Kecamatan Payung Kabupaten Karo.Metode survei deskriptif menggunakan panduan International Rice Research Institute (IRRI). Teknik penentuan lokasi secara sengaja dan pengamblan sampel secara kebetulan.Uji kandungan antosianin menggunakan metode analitik dengan menghomogenkan sampel. Hasil eksplorasi didapatkan 72 genotipe yang dibagi menjadi tiga lokasi lahan. Berdasaran uji kandungan antosianin didapatkan lahan A memiliki kandungan tertinggi yaitu 0,5 mg/100 g dan terendah yaitu lahan B 0,08 mg/100 g.

Experiments were carried out to assess some insecticide modules against major insect pests of rice. Each module consists of a basal application of carbofuran 3G @ 1 kg a.i ha-1 at 20 DAT and Rynaxypyr 20 SC @ 30 g a.i ha-1 at 45 DAT except untreated control. All modules differ with each other only in third treatment which was applied in 65 DAT. The third treatment includes: Imidacloprid 17.8 SL @ 27 g a.i ha-1, Pymetrozine 50 WG @ 150 g a.i ha-1, Triflumezopyrim 106 SC @ 27 g a.i ha-1, Buprofezin 25 SC @ 250 g a.i ha-1; Glamore (Imidacloprid 40+Ethiprole 40% w/w) 80 WG @ 100 g a.i. ha-1, Thiacloprid 24 SC @ 60 g a.i ha-1, Azadirachtin 0.03 EC @ 8 g a.i ha-1, Dinotefuran 20 SG@ 40 g a.i ha-1 and untreated control. All the treated plots recorded significantly lower percent of dead heart, white ear- head caused by stem borer and silver shoot caused by gall midge. Module with Pymetrozine 50 WG @ 150 g a.i ha-1 treated plot recorded significantly higher per cent reduction of plant hoppers (>80% over untreated control) and produced higher grain yield (50.75 qha-1) than the other modules. Among the different treated modules the maximum number of spiders was found in Azadirachtin 0.03 EC @ 8 g a.i ha-1 treated module plot followed by other treatments.

Tujuan dari penelitian ini adalah untuk mengetahui pengaruh aplikasi abu sekam terhadap kandungan prolin dan silikat daun serta kualitas hasil yaitu protein dan amilosa biji padi gogo dan hubungan korelasi antar keempat komponen tersebut pada kondisi pertanaman 80 persen kapasitas lapang pada skala pot. Penelitian dilakukan di polibag dalam screen house Fakultas Pertanian Unsoed dengan menggunakan rancangan acak kelompok pola faktorial dengan faktor varietas (Situ patenggang, Limboto, Towuti, Batutegi dan Aek sibundong) dan faktor abu sekam (0, 2, 4, 6 t/ha), diulang tiga kali. Hasil penelitian menunjukan bahwa pemberian abu sekam dosis 2−6 t/ha mampu meningkatkan kandungan silikat daun antara 18,49−29,43% dan menurunkan kandungan amilosa biji pada lima varietas sekitar 4,19−6,92%. Pemberian abu sekam dosis 2−6 t/ha mampu meningkatkan kandungan prolin daun antara 27,56−70,63% dan protein biji antara 2,35−16,71%. Antarvarietas menunjukan bahwa kandungan prolin tertinggi dihasilkan oleh varietas Batu tegi 18,58 persen dan protein biji pada varietas Situ patenggang 9,55%. Terdapat korelasi antar karakter fisiologis yaitu antara silikat-prolin (0,62) dan kandungan protein-amilosa biji (-0,78).
