The spesies composition of arthropods on agro-ecosystem can be seen as a general indicator for ecosystem stability and ecological resilience. Agricultural intensification has been linked with losses of biodiversity and disruption of key ecosystem services in farmed landscapes. This study aimed to determine how cropping system and farming systems able to increase the diversity of insects on potato field, that can be used as an integrated pest management strategy. The result showed that insect diversity index and population of natural enemies in polyculture cropping system is higher than monoculture cropping system, while the pest population is lower. Insect diversity index and population of natural enemies in organic farming systems is higher than conventional farming systems, in general the pest population was lower in conventional farming systems, but not significant with organic farming system. The polyculture cropping potatoes+cabbage+mustard+celery, potatoes+cabbage, potato+mustard respectively which grown by organic farming systems provide the highest insect diversity index, the lowest percentage of crop damage, the lowest populations of pest, and the highest natural enemy populations when compared with the same polyculture cropping with conventional farming systems.Â Keywords: Cropping system; farming system; insect diversity; potato

Potato production in Karo and Simalungun Regency of North Sumatra is severely limited by the high number of pest attacks, so that the use of pesticides is absolutely necessary. Increasing potassium doses and application botanical pesticides can be used as a strategy to reduce pest attacks on potatoes. This study aims to determine whether an increase in potassium dose and application of some botanical pesticides can reduce the percentage of pest attacks and then increasing potato production. Research was designed by factorial Randomized Block Design (RBD) with 2 factors, namely Potassium Dosage consist of 4 levels: K0 = Control; K1 = 100 kg / ha (30 g / plot); K2 = 150 kg / ha (45 g / plot); K3 = 200 kg / ha (60 g / plot). And the second factor is the type of botanical pesticide which consist of 3 levels, namely: N1 = 20 g Neem leaves/ liter of water; N2 = 20 g babadotan leaves/ liter of water; N3 = 20 g Kipahit leaves/ liter of water. Data were analyzed by analyzed of variance.The results showed that an increase in potassium dosage did not significantly affect the percentage of pest attacks and plant production variables. Botanical pesticides have a significant effect on the percentage of pest attacks, but have not significant effect on crop production variables. The lowest percentage of pest attacks was obtained from the application of botanical pesticides from babadotan leaf extract. In general, the percentage of pest attacks in the category was very low (<25%), so that not significantly affect to production variables.

Green peach aphid (MyzuspersicaeSulze) represents one of the major pest affecting decreased production which found in different potato fields in Karo highland. Decreasing incurredin two ways: the direct damages that are caused by the insectfeeding on the plants and the indirect damages caused to potato planting materials as a virus vector. There are different methods for controlling green peach aphids, all of them relying inthe use of chemicals and this method makes food production contaminated by pesticide residu. So, using non-chemical methods of cultivation contribute to “ecological” food production.Intercropping is one way of reducing pest insect populations in such vegetable crops.This study was conducted to determine the population dynamics of Myzuspersicae (Sulzer) on Intercropping system of potato plant with other vegetables plant on Karo Highland. The host plant was cultivar Granola of potato and the intercropping plant respectively were cabbage, mustard, celery, onions, carrot and bean. The results showed that M. persicae was consistently at different densities in different intercropping plant on potato. The aphid was first recorded at three week until planting. The kind of inter cropping culture plants significantly reduced the number of aphid. The lowest number of aphid found respectively inintercroppingpotatoesandmustard, potatoesandonions, andpotatoesandcelery. There was 0.80 aphids /leaf, 1,12aphids/leaf, 1,48 aphids/leaf. At the 2nd observation found the number of aphid was lowest atpolyculture potatoes and mustards were 1,68 aphid/leaf, at popatoes and onions were 3,28 aphid/leaf, at popatoes and celery 3,00 aphid/leaf. The number of aphids steadily increased with significant at differencesintercroppingplant till the 3rd observation (9 weeks until planting) respectively where 2,80aphid/leaf, 3,42 aphid / leaf and 4,20 aphid/leafwere recorded. Observation for natural enemies of M. persicaeshowed that fewnatural enemiesfound in theagro-ecosystem. There are Episyrphusbalteatus, Chrysoperlacarnea, phidiusmatricarieae and Coccinellaseptempunctata. The population density of all of the natural enemies was highest at polyculture than monoculture of potato. After that, as the population of M. persicae started decline, the same trend was followed by all of its natural enemies.

Desa Ujung Bawang merupakan salah satu desa sentra tanaman cabai, berhubung potensi agroklimatnya yang mendukung pertumbuhan dan produksitanaman. Namun, selama beberapa tahun belakangan Desa ini mengalami kemarau yang berkepanjangan. Hal ini menjadi masalah besar bagi petanicabai yang hanya mengandalkan air hujan untuk pengairan, sehingga terjadi gagal panen cabai. Petani juga kesulitan memperoleh pupuk subsidi dari pemerintah karena terbatasnya persediaan, dan di pasaran pupuk langka serta harganya mahal. Melalui program kemitraan dengan petani, telah dilakukan penerapan teknologi dengan metode irigasi tetes dari sumber mata air yang berada dekat lahan petanikemudian mengalirkannya ke lahan dengan sistem kontrol. Selanjutnya dilakukan pelatihan pengolahan limbah kulit ceri kopi menjadi kompos. Kegiatan ini memberikan dampak positif kepada petani mitra, yaitu: petani tidak kesulitan lagi untuk mengairi tanamannya; petanitidak tergantung pada pupuk subsidi maupun pupuk yang dibeli dari luar; dan peningkatan pengetahuan dan keterampilan tentang pengolahan limbah menjadi kompos. Kompos yang dihasilkan memenuhi beberapa kriteria SNI 19-7030-2004. Penelitian menunjukkan bahwa penerapan teknologi memberikan penurunan biaya produksi sebesar 39,05% dan peningkatan pendapatan sebesar 12,4% dari petani yang belum memanfaatkan teknologi. Walaupun produksi yang diperoleh lebih rendah dari petani yang belum memanfaatkan teknologi (2,93%), hal ini disebabkan lahan baru pertama sekali ditanam cabai. Kata kunci: Cabai, Irigasi tetes, Limbah, Kompos ABSTRACT Ujung Bawang Village is one of the centers of chili plantation due to its agro-climate that supports growth and production. However, these past years the village experienced prolonged dry season. This became a problem with chili farmers that depended only on rainwater, which caused production decline. Aside from that, farmers also experienced difficulties acquiring subsidized fertilizer from the government due to supply limit and lack of stock or unaffordable prices in stores. Through partnership program, we’ve applied a technology with drip irrigation method from water source near the land with control. Training to process coffee cherries waste to become compost was also done. These resulted in positive impacts to farmers, which are: (1) no difficulty to irrigate plants; (2) not dependant on subsidized or purchased fertilizer anymore; (3) knowledge and skill advancement to process waste into compost. The compost produced passed some of SNI 19-7030-2004 criteria. Research shows these reduce production cost as much as 39,05% and increase income to 12,4% more than farmers who haven’t applied the technology. Although production rate was lower than farmers who haven’t applied it (2,93%), this is due to soil’s first time being planted with chili. Keywords: Chili, Drip irrigation, Waste, Compost

The study aims to find out the impact of poultry and coal fertilization on the growth, production and availability of P on red onions in savage land. The study used a random group plan (RAK) with two treatment factors. Chicken cage fertilizer factor and coal coal factor use each 4 levels. The results of the study showed that the dose of real chicken cage fertilizer up to a dose of 7.5 kg/plot improved the length of the leaves, the wet weight of the bulbs/plots, the Wet Weight of the plots/bulbs, the dry weight of plants/bubbles, the Dry Weight and Root Volume, the soil content, the saturation of the base, C-organic soil, soil pH and the availability of soil P, having no real impact on the amount of bulbs. The supply of coal to a dose of 5.7 kg/plot did not have a tangible effect on all the same parameters observed with the administration of poultry cage fertilizer doses. The interaction between the dosage of chicken cage fertilizer and coal has no tangible effect on all the observed parameters.

This study aimed to determine the habitat approach on potato cultivation to increase diversity of insects. Habitat improvement design by agricultural system and planting system on different season. This study consisted of two experiments. The first done at planting season from March to July (dry season) and the second done at planting season from October to January (rainy season). Research designed by Split plot design with main plot are farming systems (inorganic farming and organic farming) and the subplot are the design of cropping system (sole potato; potato and cabbage; potato and mustard; potato and onion). The data was analyzed by ANOVA and Tukey test. The result showed that planting season from March to July (dry season) as well as the planting season from October to January (rainy season) showed that insect diversity index, predator population and parasitoid population were higher in organic farming compared to inorganic farming systems. The design of cropping system significantly affect insect diversity index,natural enemies population such as predator Coccinelids and parasitoid Braconid wasp and M. persicae population. In organic farming, intercropping potato with cabbage found the highest insect diversity index and the highest population of parasitoid Braconid wasp and the lowest population of M. persicae. The highest population of predator Coccinelids found at interropping potato with mustard. Combined analysis of the planting on dry season and rainy season showed that insect diversity index and population of parasitoid Baraconid wasp not significantly difference between planting on dry planting and planting on rainy season. On the other hand, population of predator Coccinellids and M. persicae significantly more higher at planting on dry season than planting on rainy season.

Desa Paluh Subur berada di pesisir Belawan Kecamatan Hamparan Perak, Kabupaten Deli Serdang Sumatra Utara. Secara umum kondisi penduduk di desa ini memprihatinkan dengan mata pencaharian bercocok tanam padi dengan pengairan tadah hujan satu kali dalam setahun. Produktivitasnya masih jauh dari rata-rata produktifitas nasional. Penghasilan tambahan diperoleh dari ternak dan tanaman hortikultura. Teknologi budidaya padi sawah yang dikembangkan masyarakat selama ini masih sangat sederhana dan belum memanfaatkan potensi lahan secara maksimal. Tujuan Pengabdian Masyarakat bertujuan untuk menerapkan sistem pertanian terpadu untuk memaksimalkan potensi wilayah. Metode pelaksanaan adalah Participatory approach melalui penyuluhan, diskusi, praktek langsung dan pembuatan demonstrasi plot teknologi budidaya padi sawah dengan Metode SRI yang terintegrasi dengan peternakan dan memanfaatkan potensi lingkungan sekitar sehingga produksi padi dan pendapatan petani meningkat. Hasil kegiatan demonstrasi pada plot percobaan menunjukkan ada peningkatan produksi padi sebesar 47 %, mengurangi kebutuhan bibit sebesar 88 % dan mengurangi penggunaan pupuk Anorganik sebesar 35 % sebagai akibat pemanfaatan Jerami padi sebagai pupuk organik Bokashi. Hasil kegiatan penyuluhan menunjukkan bahwa ada peningkatan pengetahuan petani dalam hal pemanfaatan jerami padi sebagai bahan organik penambah unsur hara tanaman, pemanfaatan tumbuhan sekitar sebagai bahan untuk pestisida nabati, pengenalan kebutuhan unsur hara tanaman berdasarkan warna daun dan efisiensi penggunaan air dan bibit melalui polatanam padi dengan Metode SRI. Hasil Integrasi usaha dengan peternakan kambing belum menunjukkan hasil yang signifikan sampai kegiatan pengabdian Masyarakat ini berakhir
