This paper describes the role of the insect, which is essential for human survival, but still people are not familiar with widely even some people consider insects no meaning or viewed from the downside. Diversity of epiphytes and insects in the canopy of palm oil plantations in North Sumatra assessed by field observations at five locations, namely, Bukit Sentang, Padang Mandarsyah, Ajamu, Sijambu-jambu, and Aek Pancur. Data were analyzed using qualitative and quantitative. Based on the results obtained by analysis of the biological diversity of insects that affect the quality and quantity of farm products. In natural ecosystems, generally there has been a stable population of pests and their natural enemies so that the presence of insect pests in cropping is no longer harmful. Thereby, the conditions need to be developed so as to reduce the use of pesticides to control pests in field crops, especially in export-oriented and has high economic value.

Limestone mining has the potential into environmental damage that involve modify an ecosystem. The attempt that contrived to reduce the disturbances are rehabilitation. This research was conducted to examine the growth response of Leucaena leucocephala inoculated with AMF and soil ameliorant in a limestone post-mining soil. The design used was a split-plot design in a completely randomized design with 3 factors. The first factor was AMF inoculum (Daemonorops draco AMF and MycoSilvi), the second factor was organic fertilizer of compost, and the third factor was inorganic fertilizer. The variables used in this study expressed by height, diameter, biomass, root colonization, and nutrient absorption of the plant. The analysis showed that the combination of MycoSilvi and compost 7.5% gave best result of height, diameter, and biomass, with significantly increased by 962.67%, 899.41% and 1440.67% to control plant. It also gave best result of nutrient uptake N, P, and K, with significantly increased up to 17.64 g plant-1, 2.42 g plant-1, and 18.05 g plant-1. In general, AMF showed a good percentage of root colonization with an average 36.67-86.67%. Further research is needed to determine the response to the growth of seedlings planted in the field.

“…K o n s e n t r a s i h a r a d a u n menunjukkan hasil yang tidak berbeda nyata pada pemberian pupuk anorganik briket dibandingkan tanpa pemupukan. Penelitian Ginting et al (2018) juga menunjukkan konsentrasi hara N, P, dan K pada pembibitan tanaman kelapa sawit dalam polibeg yang tidak berbeda nyata pada pemberian pupuk anorganik lambat tersedia berbentuk briket dibandingkan tanpa pemupukan. Hal tersebut dikarenakan pupuk anorganik lambat tersedia akan melepas hara kumulatif dalam jumlah yang lebih kecil dalam waktu yang sama dibandingkan pupuk tunggal (Hanifah et al, 2019).…”

Pemupukan anorganik memegang peranan penting dalam meningkatkan pertumbuhan tanaman karet pada pembibitan root trainer. Pemupukan anorganik pada pembibitan tanaman karet selain diberikan dalam bentuk cair dapat juga diberikan dalam bentuk padat seperti pupuk briket yang memiliki sifat lambat tersedia. Penelitian ini bertujuan untuk mengetahui pertumbuhan tanaman karet pada pembibitan root trainer terhadap pemberian pupuk anorganik briket. Penelitian dilaksanakan di kebun percobaan Unit Riset Bogor-Getas, Salatiga, Jawa Tengah pada bulan April sampai September 2020. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap dengan 8 perlakuan dan 6 ulangan. Perlakuan terdiri atas: 1)kontrol tanpa pemupukan; 2)pupuk cair 2 minggu; 3)briket 5 g/tanaman; 4)briket 10 g/tanaman; 5)briket 5 g/tanaman + pupuk cair 2 minggu; 6)briket 10 g/tanaman + pupuk cair 2 minggu; 7)briket 5 g/tanaman + pupuk cair 4 minggu; 8)briket 10 g/tanaman + pupuk cair 4 minggu. Pemberian pupuk anorganik briket tidak menunjukkan peningkatan pertumbuhan tinggi tanaman, diameter batang, bobot akar, bobot tanaman, dan kandungan hara daun dibandingkan tanpa pemupukan. Efektivitas agronomi relatif tertinggi ditunjukkan pada perlakuan briket 10 g/tanaman + pupuk cair 4 minggu dengan RAE 145%. Hal tersebut berarti bahwa penambahan pupuk anorganik briket 10 g/tanaman dapat mengurangi frekuensi pupuk cair dengan efektivitas agronomi relatif yang sudah lebih tinggi 45% dibandingkan pupuk cair 2 minggu.
