Abstrak : Pelaksanaan Pengabdian kepada masyarakat dilakukan untuk menjawab masalah petani dalam teknik budidaya padi lokal “Banga Laka” yang terindikasi menggunakan pestisida sintetik berlebih, selain itu petani tidak mengenal jenis hama yang menyerang tanaman padi sehingga cenderung penggunaan pestisida tidak tepat sasaran. Solusi yang ditawarkan oleh tim PKM yaitu menerapkan teknologi light trap yang terbukti efektif mengendalikan hama pada tanaman padi. Metode yang digunakan pada kegiatan ini adalah 1) penyuluhan berkenaan dengan pengenalan dan perawatan alat light trap dan 2) pengamatan langsung dilapangan untuk melihat jenis-jenis hama yang terperangkap pada light trap. Evaluasi efektivitas light trap dilakukan dengan metode partisipatif dimana masyarakat ikut melakukan pemantauan hama yang terperangkap pada setiap jenis perangkap dan melakukan perhitungan penghematan biaya produksi. Pemasangan light trap selama satu bulan dapat menekan penggunaan jenis pestisida sebesar 83,86% dengan penghematan biaya pengendalian hama sebesar Rp. 1.325.000/musim tanam, berdasarkan pengamatan diketahui bahwa light trap berhasil menangkap 7 jenis hama (881 ekor) dengan proporsi tertinggi pada jenis cahaya ungu (49%).Abstract: The implementation of community service is carried out to answer farmers' problems in the local rice cultivation technique "Banga Laka" which is indicated to use excess synthetic pesticides, besides that farmers do not know the types of pests that attack rice plants so that they tend to use pesticides not on target. The solution offered by the PKM team is to apply light trap technology which is proven to be effective in controlling pests on rice plants. The methods used in this activity are 1) counseling regarding the introduction and maintenance of light traps and 2) direct observation in the field to see the types of pests trapped in light traps. Evaluation of the effectiveness of light traps is carried out using a participatory method where the community participates in monitoring pests trapped in each type of trap and calculating production cost savings. Installing a light trap for one month can reduce the use of pesticides by 83.86% with a pest control cost savings of Rp. 1.325.000/planting season, based on observations it was known that the light trap managed to catch 7 types of pests (881 individuals) with the highest proportion in the type of purple light (49%).

Addition of Decomposers as Stimulators for Increasing the Effectiveness of Vegetable Pesticides. This study aims to determine the increased effectiveness of plant-based pesticides added with several types of decomposers. This study uses a Completely Randomized Design (CRD), with 5 treatments and 5 replications namely: FO: Control (water), F1: Plant pesticides without the addition of decomposers, F2: Vegetable pesticides + EM-4, F3: Vegetable Pesticides + Promi, F4 : Vegetable Pesticides + rice washing water. Observation variables consisted of mortality of contact poison, stomach poison, Lethal Time (LT 50%) and the speed of death as well as the attitudes and eating behavior of Parmarion martency. The results showed an increase in the effectiveness of plant-based pesticides that were significantly different from the control but not significantly different in each treatment where F3 treatment increased mortality by 0.05% (contact poison) from pesticide extracts without the addition of decomposers while the effectiveness of stomach poison only increased by 0, 14%. The fastest 50% lethal time in F3 treatment with 50% LT period was 48.4 hours with a mortality rate of 0.8 hours / individual in contact poison and 50% LT in stomach poison for 52.0 hours with a death rate of 0.6 hours /individual. Changes in behavior due to contact poisons are characterized by releasing grayish white fluid and then death is characterized by a rigid body that is easily reversed, and stomach poisoning behavior is characterized by experiencing less active, being in one place and dying in reverse.

The goal of this research was to understand the diversity of soil mesofauna native to different plant habitats in the area of Kelimutu National Park and to understand how the dominant soil mesofaunal populations vary depending on vegetative diversity. This research was conducted in a number of different vegetation habitat zones according to the intensity of land use in the area of Kelimutu National Park and in the laboratories at the University of Flores in the city of Ende. This research was designed in a linear method and sampled vegetation from areas labelled VR (Vacciniumvaringiaefoliumdan Rhododendron renschiamum), VCa (mixed forest) and VC (coniferous forest). The results of this research show that the area near Kelimutu National Park contains low to medium diversity. Low diversity was observed in areas with vegetation VR with5 types of soil mesofauna (H’:1.153) whereas medium diversity was observed in areas with vegetation VCa, with researchers finding 7 types of soil mesofauna (H’:1.771). Six types of soil mesofauna were found in areas with vegetation type VC (H’:1.727). Vegetative diversity was found to be linked to the increasing dominance of soil mesofauna in the area of Kelimutu National Park. The highest value of vegetative diversity was (H’:1.821), found in area VCa with the dominance of soil mesofauna (E:0,85). For area VR, the vegetative diversity was (H’:1,771) with a dominant soil mesofauna value of (E:0.72) and for vegetation VC the vegetative diversity was (H’:0.861) with dominant soil mesofauna value of (E: 0,28).

The goal of this research was to identify the dryland cereal crop seed plasma types growing around Kelimutu National Park, located in Ende district on the island of Flores in Indonesia, by observing crop morphology and cultivation techniques. Cereal crops represent the largest source of carbohydrates in the regional diet in comparison to other food groups in this area where dry land makes up 80% of the total available land. It is estimated that the Ende district of Flores has adequate potential to produce dryland cereal as a staple food crop. Previous studies have shown that farmer preference is shifting towards the cultivation of crops with a higher economic value which threatens the existence of some cereal crops. Concurrently, shifts in eating habits have made rice a staple food in this region, leading to increased consumption and threatening the existence of other cereal crops. Furthermore, outsiders tend to think of areas like Flores as being impoverished, with frequent problems with food security. Currently, there is a lack of knowledge within the youth population about the types of foods, especially cereals, which are rich in nutrients and their use in rituals. This research aims to address this gap by collecting information on cereal crops in and around Kelimutu National Park for dissemination through educational and cultural tours. This study was conducted in the eastern subdistrict of Ndona, Flores and Wolojita Detusoko between June and December 2011. Study findings identified 5 main cereal crops: paddy fields (consisting of: Are Rumba, Are Sela, Are Obo, Are Laka, Amera, Eko Ndale, Kea Ria, Are Mera, Are Kea Mboa, Eko Ena), corn (consisting of Java Roga, Nggela Java, Java, Keo Ri’a), sorghum (consisting of mera Lolo, Lolo Mite and Lolo Telo Leko), barley (consisting of Mera and Wete Wete Bara) and millet (consisting of Ke’o Mite and Ke’o). Of the five types of cereal crops identified, one type (Pega, a subspecies of barley with a sorghum-like panicle) is not found in four of the districts. It was found that corn, classified as a native plant, is strengthened through cultivation by re-seeding. Study results illustrated that corn in this area is of reduced genetic quality, as illustrated by the fact that 3-4 cobs did not develop. Alternatively, the Ke’o Bara strain of barley has a morphology and panicle strand number (270-300) that suggest that this species is typical of this region.

The aim of this research is to identify Liromiza spp. And the parasitoid is associated with various types of vegetable plants in Detusoko and Kelimutu Districts in Ende Regency. Data were analyzed by matching morphology of existing specimens with insect morphology books written by Bhorror 1970 and matching with standard specimens originating from Bali and Bogor. The results obtained from two vegetable producing districts in Ende, namely Detusoko and Kelimutu, show the following: There are two types of Liriomyza spp associated with several types of host plants in Ende Regency. L. huidobrensis (Diptera: Agromyzydae) is located in Kelimutu District and L Sativae (Diptera: Agromyzydae) is in Detusoko District. The diversity of parasitoids found in Detusoko Subdistrict were as many as four species from the Eulopidae family while in Kelimutu District there were five types of parasitoids originating from two families namely Braconidae and Euiopidae. Neosacharis okazaki is the most dominant type of parasitoid in each plant in Detusoko District. Opiits sp dominant in Kelimutu Subdistrict on the long bean, green beans, mustard greens, chicory and cabbage. While H. varicornis is dominant in Kelimutu District in tomato plants.

Brontispa longissima Gestro (Coleoptera: Chrysomelidae) is ones of the most important pest who attack of many family palms in South East Asia. In Indonesia, Brontispa longissima has. becomes a primer pest on coconut. It was Decreasing yield result up to 30 - 40 % returns and 5% of the attacked crops will die. Ones of the failed reason of control action is a low preventive system on every territory entrance, otherwise, coconut was a needful and fast-moving commodity for people and industry. The second reason is secondary commodity assumes and low cropping system caused pest and disease uncontrolled. Three bio-control usages on-field need to monitored caused farmers incapable. The success indicator for parasitoid release was quick and easy to adapt for the parasitoid. It was related " three-generation three years," theory by Ev Clausen, the expert of integrated pest and management control from California says: a) The perfectly of Effective parasitoid/predator always quick and easy to adapt, b) The failed parasitoid/predator to adapt easily and quickly was an ineffective indicator for bio-control, c) Parasitoid release or exotic predator could be stopped for 3 years if no evidence adapt on fields. According to the experts, the key for the success of system controlling above depends on cropping agroecosystem stability.
