Kebijakan subsidi pupuk merupakan salah satu kebijakan yang penting di bidang pertanian di Indonesia. Selain itu, kebijakan yang dilakukan oleh pemerintah kebijakan Harga Pembelian Pemerintah (HPP). Kebijakan ini bertujuan ntuk melindungi petani dari jatuhnya harga gabah pada saat panen raya. Tulisan ini mengkaji dampak kebijakan subsidi pupuk dan HPP bagi produsen dan konsumen. Data yang digunakan adalah data time series tahunan dari tahun 1981 sampai 2014 dengan model ekonometrika persamaan simultan. Hasilnya menunjukkan bahwa surplus produsen dan surplus konsumen dipengaruhi oleh kondisi pasar beras domestik. Surplus produsen akan dicapai jika pemerintah menerapkan kebijakan jaminan harga berupa peningkatan Harga Pembelian Pemerintah (HPP), sedangkan surplus konsumen akan dicapai jika pemerintah menerapkan kebijakan peningkatan subsidi input berupa kredit pertanian dan subsidi pupuk serta peningkatan produktivitas areal. Untuk meningkatan surplus produsen dan konsumen secara merata maka perlu diterapkan paket kebijakan yang merupakan kombinasi dari kebijakan subsidi pupuk dan kebijakan HPP.

Upper Ciliwung watershed is classified as watershed of which its carrying capacity is restored as it has indicator qualification of high until very high and it is important to be handled. This study was aimed to analyze the cability of upper Ciliwung watershed area for the development of sustainable agroforestry. The units of land use (SPL) used for intensive observation were as many as 60 units of land use spread over seven (7) sub-watershed, namely sub-watershed of Cibalok, Cisuren, Ciliwung, Ciesek, Cisukabirus, Cisarua and Ciseseupan. The unit of land use of which its land capability class was analyzed included the use of shrub land, open land and dry land agriculture. The unit of land use will be used as a recommendation for the use of agroforestry in upper Ciliwung watershed. The results showed that the land capability class in the upper Ciliwung watershed consisted of land capability class II, covering an area of 329.7 ha (23.92%), capability class III of 464.8 ha (33.72%) and capability class IV of 584 ha (42.36%). Land use of upper Ciliwung watershed was dominated by class III with dominant obstacle factor namely bumpy slope. Analysis of land capability on shrubland, open land, and dry land agriculture which spread over the unit of land use in the area of upper Ciliwung watershed was generally recommended for land use of agroforestry-agrisilvopasture and agroforestry-agrisilviculture.Keywords: Land capability, land use, agroforestry, upper Ciliwung Watershed

The use of various types of active ingredients with high intensity pesticides in dealing with pest disturbances often makes farmers pay less attention to the negative impacts. Deltamethrin, sipermetrin, λ-cyhalothrin and chlorpyrifos are active ingredients of pesticides that are often used by cocoa farmers to control pests Helopeltis sp. spp. which is one of the main pests in cocoa plants. Field tests on pesticide application were carried out on cocoa plants with Helopeltis sp. spp. High. This test was carried out on 4 treatment blocks applied with different active ingredients. Pesticide residue testing was carried out on cocoa beans, before and after pesticide application using the QuEChERS method on GC-ECD. The results of pesticide residue testing showed that the use of λ-cyhalothrin pesticides did not leave pesticide residues, while sipermetrin pesticides left far fewer pesticide residues compared to deltamethrin and chlorpyrifos pesticides. The results of these pesticide residues are compared to the Pesticide Maximum Residual Limit (MRL) according to the European Commission Part A of Annex I to Reg. 396/2005, shows the results of λ-cyhalothrin and cipermethrin pesticide residues test under pesticide MRL, while the results of deltamethrin and chlorpyrifos pesticide residue test are above the specified pesticide MRL.

Alkaloid kinkona adalah senyawa aktif yang terkandung dalam tanaman kina. Alkaloid kinkona diisolasi dari kulit batang pohon kina. Secara kimia, alkaloid kinkona memiliki 2 bagian molekul utama yaitu cincin aromatik kuinolin dan cincin non-aromatik kuinuklidin yang dihubungkan dengan gugus alkohol sekunder pada karbon C-9. Struktur ini banyak mendapat perhatian di dalam penelitian kimia obat. Kami mempelajari aktivitas biologis yang dimiliki oleh alkaloid kinkona. Alkaloid kikona telah diketahui berfungsi sebagai antimalaria, akantetapi beberapa penelitian terbaru menunjukkan bahwa alkaloid kina memiliki fungsi lain yang berpotensi seperti anti-kanker, anti-tumor, anti-mikroba, anti-HBV, anti-inflamasi, anti-oksidan, anti-obesitas. Ulasan ini menggambarkan kompilasi komprehensif aktivitas biologis berbagai turunan alkaloid kinkona. Kami berharap ulasan artikel ini dapat memberikan kontribusi dalam penyebaran informasi ilmiah terkait kimia medisinal khususnya tentang spektrum aktivitas biologi senyawa turunan alkaloid kinkona.
