This study aims to determine the effect of kenikir leaf extract (Cosmos caudatus) on the mortality of Grayak Caterpillars (Spodoptera litura). This type of research is a laboratory experiment, with the design used is a Completely Randomized Design (CRD) consisting of five treatments and five replications. The treatments were P0 + as a control, P1 with a concentration of 25%, P2 with a concentration of 50%, P3 with a concentration of 75%, and P4 with a concentration of 100%. Data analysis techniques with steps: normality test, homogeneity test and one way anova test. Research Results, based on the One Way Anava calculation, it was obtained that Fcount = 11.40 with Ftable = 4.43. then it can be stated that the value of Fcount> F table then H0 is rejected and H1 is accepted. In the BNJ (Honest Significant Difference) test, the significance level of 1% of the effect of kenikir leaf extract on treatment A 25% (P1) was not significantly different from the concentration of 50% (P2) and 75% (P3), and at treatment D 100% (P4 ) is not significantly different from ACD, the treatment E (P0 +) is very significantly different from ABDE. Conclusion, there is a very significant effect of kenikir leaf extract (Cosmos caudatus) on mortality of armyworm caterpillar (Spodoptera litura), the higher the concentration of insecticide given, the higher mortality of armyworm caterpillar.

This study aims to determine the effect of a combination of compost and chemical fertilizers on soybean (Glycine max L.) production. The research method used was a completely randomized design (CRD) using four treatments and six replications. The combination treatment of compost and chemical fertilizers, namely NPK fertilizer (control) (P0), straw compost + NPK (P1), coffee husk compost + NPK (P2) and vegetable waste compost + NPK (P3). The research data were analyzed by one factor ANOVA using SPSS 16 and continued by using the LSD test at the 5% real level. The results showed that the best treatment to increase the number of pods and dry weight of seeds was the P1 treatment (straw compost + NPK), but it was not significantly different from the P3 treatment (vegetable compost + NPK). In conclusion, there is an effect of a combination of compost and chemical fertilizers on soybean production (Glycine max L.).

The Community Partnership Program that our team proposes is expected to help the people of Mojorejo Village in the manufacture and marketing of fragrances from coffee beans. Mojorejo Village located in Selupu Rejang District is an agricultural area that produces many types of agricultural crop commodities in the form of vegetables and coffee. Not many people know that apart from being sold raw and made into coffee grounds, they can also be used as fragrances. The fragrance from the coffee beans produced can be used as a car or room fragrance. Fragrances from the coffee beans produced can be traded offline or online at competitive prices. Thus the product in the form of fragrance from coffee beans can also increase income for residents. But unfortunately, the people of Mojorejo Village do not yet have the knowledge and skills in making and marketing coffee beans as air fresheners or cars. To achieve this goal, we as a team tried to use four methods, namely observation, socialization, training and continued with direct practice. The long-term goal of this activity is to create business opportunities for the residents of Mojorejo Village by using coffee beans to make air fresheners for rooms and cars. The output targets of the activity are (1) knowledge, skills and income of partners increase, (2) produce a product in the form of fragrance from coffee beans. Publication output target: service results published in community service journals.

Program ini bertujuan untuk membantu masyarakat Beringin Tiga pada umumnya dan kelompok tani khususnya dalam dalam pemasaran dan manajemen usaha produk pupuk organik cair yang telah berhasil mereka produksi. Limbah sayuran di daerah ini cukup besar karena berasal dari pengumpul sayuran di desa-desa sekitarnya. Selain menyebabkan polusi dan kerusakan lingkungan, limbah sayuran juga dapat membahayakan keselamatan pengguna jalan karena limbah sayuran dibuang di bahu jalan penghubung provinsi yang menyebabkan tanah longsor. Selain mampu mengatasi masalah pencemaran dan kerusakan lingkungan, kegiatan ini juga dapat membantu meningkatkan perekonomian masyarakat desa setempat. Untuk mencapai tujuan ini metode yang digunakan adalah observasi, sosialisasi, pelatihan dan dilanjutkan dengan praktik langsung. Hasil dari program ini yang telah dilakukan adalah mitra memiliki pengetahuan untuk mengemas, mempromosikan, memasarkan dan mengelola bisnis pupuk organik cair. Selain itu mitra memiliki kemampuan dan keterampilan dalam memproduksi dan memasarkan pupuk organik cair dari limbah sayuran. Mitra juga mampu memasarkan produk pupuk organik cair dengan keuntungan Rp. 1.274.000 dalam satu produksi. Hasil dari program ini juga berupa pembentukan koperasi sederhana.
