Padi (Oryza sativa L.) merupakan makanan pokok sebagian masyarakat di Indonesia. Hambatan yang terjadi yaitu musim panen padi yang tidak sesuai harapan petani. Perbaikan sifat fisik dan kimia tanah untuk peningkatan produktivitas lahan kering dapat dilakukan diantaranya dengan penambahan bahan organik. Oleh karena itu, produktivitas padi harus ditingkatkan, salah satunya dengan aplikasi POC keong mas dan pklobutrazol. Tujuan penelitihan ini, yaitu untuk mengetahui pengaruh POC keong mas dan paklobutrazol terhadap pertumbuhan dan anatomi tanaman padi (Oryza sativa L.). Untuk menentukan berapa konsentrasi POC keong mas dan paklobutrazol yang efektif meningkatkan pertumbuhan dan anatomi padi (Oryza sativa L.). Rancangan yang digunakan dalam penelitian ini adalah rancangan acak kelompok lengkap (RAKL) pola faktorial, dengan 2 faktor perlakuan yaitu dosis POC keong mas dan paklobutrazol. Dosis pupuk organic cair terdiri atas 4 tingkat, yaitu: kontrol = 0ml/L (C0), 1 ml/L(C1), 1,5ml/L (C2), atau 2ml/L (C3). Aplikasi pupuk organik cair dilakukan pada saat tanaman padi berumur 4, 8 dan 12 minggu setelah pemindahan. Dosis pemberian paklobutrazol pada tanaman padi dengan 4 tingkat, yaitu: Perlakuan kontrol =  0 ppm paklobutrazol (P0), 5 ppm paklobutazol (P1), 10 ppm paklobutazol (P2), atau 15 ppm paklobutazol (P3). Analisis ini dilakukan dengan menggunakan Software SPPS 21 pada  taraf 5%. Pemberian POC keong mas dan paklobutrazol memberikan pengaruh pada tinggi tanaman, jumlah daun dan umur keluarnya daun bendera pada tanaman padi Mapan P-05. Kata Kunci: Padi Mapan P-05; POC; keong mas; paklobutrazol; pertumbuhan

This study aims to examine the response of cayenne pepper plants to the treatment of paklobutrazole with various concentrations. This study used a completely randomized design (CRD) with 6 treatment concentrations of paklobutrazole, namely: 0 ppm, 100 ppm, 200 ppm, 300 ppm, 400 ppm, and 500 ppm, with 4 repetitions. The parameters observed were: plant height, flowering time, and the number of flowers of chili plants. Data analysis used Analysis of Variance (ANOVA) according to the experimental design at a significance of 0.5. The follow-up test used the BNT test at a level of 0.05 if there was a significant effect. The results showed that the administration of paclobutrazole with a concentration of 500 ppm gave a better effect on plant height, flowering time, and number of leaves compared to other treatments.

Vegetable insecticide is a natural material that is environmentally friendly. This material can be used in the prevention and control of mosquito larvae, especially Culex sp. Culex sp is the main vector of filariasis disease and dengue hemorrhagic fever (DHF). Use of natural materials is very good and environment friendly as insectcide compared with chemicals. Avocado seed extract (Persea americana Mill) is known to have secondary metabolite content of alkaloids, saponins, triterpenoids while soursop extract (Annona muricata L) in the form of acetogenin, squamocin and annonacin. This research needs to use of avocado seed extract (P. americana Mill) and soursop seed extract (A. muricata L) as larvacide of Culex sp. The aim of this research is to know the effect of avocado seed extract (P. americana Mill) and soursop seed extract (A. muricata L) to mortality of Culex sp Instar III mosquito larvae and LC50 for 24 hours. This study was an experimental study using a complete randomized design (RAL) with five treatment concentrations (0, 2, 4, 6, and 8%) avocado seed extract (P. americana Mill) and soursop extracts extract (A. muricata L) as much as five repetitions. The data obtained were analyzed by using One Way ANOVA to show the effect on the treatment. The results showed that giving of avocado seed extract (P. americana Mill) with 8% concentration (23,8 ± 0,45 larvae) was optimal in killing Culex sp mosquito larvae. While giving soursop seed extract (A. muricata L) with 4% concentration (25 ± 0,0 larva) optimal in killing Culex sp mosquito larvae. Avocado seed extract (P. americana Mill) has an effect as a larvacide against Culex sp. instar III with LC50 at concentration 2,486% while soursop extract (A. muricata L) with LC50 value at concentration 1,605%.   Keywords: Larvacide, soursop seed extract, avocado seed extract, Culex sp

The purpose of this study was to determine the effect of variations in the number of tilapia (Oreochromis nilotics) on the growth of Pagoda mustard (Brassica narinosa) with aquaponic systems. The study used a completely randomized design (RAK) with three treatments and nine replications. The treatment in this study was the difference in the number of fish (40, 60 and 80 fish) used in the aquaponics system. The study was conducted for 45 days, the parameters observed were the number of leaves, total chlorophyll content and wet weight of the mustard mustard plant (Brassica narinosa). The research data were analyzed using the Analysis of Variance test, if it had a significant effect then the analysis was continued with the Duncan Multiple Range Test (DMRT) test. The results of the analysis of variance in the number of leaves and the total chlorophyll content of the Pagoda mustard plant (Brassica narinosa) in this study showed significant results (P<0.05), the wet weight obtained a significance of 0.077 (P>0.05). It can be concluded that variations in the number of tilapia affect the number of leaves and total chlorophyll content, but have no effect on the wet weight of Pagoda mustard greens (Brassica narinosa). The results of the Duncan Multiple Range Test (DMRT) showed that the number of tilapia fish had the most effect on the number of leaves and total chlorophyll.   Keywords: Aquaponics, Tilapia, Mustard Pagoda, Growth.
