Abstract: This research is a quasi-experimental study that aims to determine the comparison of students' mathematical communication abilities with the cooperative learning model of the NHT and PPT media in class VII SMP Negeri 02 Ngabang. The population in this study were all students of class VII SMP 02 Ngabang consisting of 3 classes. The sample in this study was taken by using the Random Sampling Cluster technique. Class VII A as class I experimental class with 24 students and class VII B as a experimental class II with 24 students. The instruments used were pretest and posttest in the form of description. Data analysis uses the t test with a significance level of 5%. The results showed the average posttest for the NHT class was 72.5 and the average posttest for the PP class was 66.666. From the posttest hypothesis test results obtained t hitung> t tabel (1.9522> 1,667). Because t_hitung> t_tabel, H_0 is rejected and H_a is accepted. This means that students' mathematical communication skills taught with the NHT are better than using Power point media.

Wabah Covid-19 sebagai pandemi yang menular secara cepat dan masif. Satu-satunya cara memutus mata rantai penularan melalui pembatasan pergerakan orang. Pemerintah Indonesia memberlakukan kebijakan Pembatasan Sosial Berskala Besar dalam Peraturan Pemerintah No. 21 Tahun 2020 guna melindungi masyarakat. Di sisi lain pemberlakuan kebijakan PSBB Covid-19 justru menimbulkan kesulitan ekonomi bagi beberapa golongan masyarakat. Seperti perusahaan transportasi, pariwisata, hotel, restoran, pedagang harian dan lainnya. Tidak sedikit pula perusahaan yang melakukan PHK atau merumahkan karyawannya. Kesulitan ekonomi membawa akibat pelaksanaan perjanjian yang sebelumnya telah berjalan lancar, tiba-tiba tidak dapat lagi dipenuhi karena debitor mengalami pengurangan atau bahkan kehilangan penghasilan. Berbagai kewajiban berdasarkan perjanjian tidak lagi dapat dipenuhi. Hukum memandang hal yang menyebabkan perjanjian tidak terpenuhi yaitu karena wanprestasi atau karena force majeure. Perlu dikaji apakah PSBB Covid-19 dapat dijadikan force majeure oleh debitor, bagaimaan pembuktian force majeure PSBB Covid-19 mengingat adanya adagium feiten notoir, serta akibat PSBB Covid-19 sebagai force majeure. Untuk mengkajinya dilakukan penelitian yuridis normatif dengan pendekatan peraturan perundang-undangan dan juga pendekatan konseptual terhadap force majeure. Hasil penelitian menunjukkan bahwa PSBB Covid-19 tidak melekat secara otomatis pada semua debitor tetapi harus dibuktikan secara personal kepada kreditor. PSBB Covid-19 merupaka force majeure yang relatif dan mengakibatkan suatu ketika kewajiban debitor kembali dapat ditagih kreditor.

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.

The use of inorganic fertilizers and pesticides can change the agroecosystem gradually. These changes may result in a decrease in the diversity of soil organisms. These organisms are very important in the decomposition process of reforming the organic matter into compounds that are readily absorbed by plants. Other changes include a change in the soil structure which will affect the soil chemical and physical characteristic and ultimately affect the soil productivity leading to a decreased agricultural product. The return of the remains from harvest, litter and crop residues from coffee and cocoa crops to the soil will provide energy for soil organisms and it will help maintain the soil environment that supports the life of other organisms. This research aimed at identifying the composition and diversity of mesofauna formed by the composted organic matter in cocoa and coffee plantations. Soil sampling was conducted on coffee and cocoa plantations in the Onelako village of Ndona District. Soil sampling was conducted in September 2010. Soil sampling used Neuman method of 0-15 cm and 16-30 cm depth. Each soil sample was taken to the laboratory. The separation of mesofauna from soil used Berlese-tullgran method that had been modified for 4 days. The separated Meso fauna was identified under the light microscope. The result of this research showed that the highest composition of mesofauna decomposer of organic matter in cocoa and coffee vegetation is Collembola. Collembola is very tolerant to acidic soil condition and they are dominant in the soil and surface habitats that contain lots of litter. Collembola is microarthropods that have large distribution both in quantity and diversity. The highest diversity of mesofauna on coffee vegetation is 1.525 and on cocoa, vegetation is 1.273. It was also noted that at a depth of 0-15 cm there was a higher concentration of mesofauna in the coffee vegetation area, which was about 7.3960, while in the cocoa vegetation there where 3.6376. The high level of the diversity index caused an increase in decomposition and therefore better soil fertility.

Brontispa longissima Gestro (Coleoptera: Chrysomelidae) is one of the important pests that attack the palm plants in Southeast Asia. There is a reported decline in the productivity of palm plants when the pest attack reaches 30-40% with 5% of the plants attacked dying. B. longissima pest attacks plants at all stages of life, but its attack is most prevalent when plants reach the age of 4-5 years. The spread of pest B. longissima has ben reported in the district of Ende, Nangakeo and Ndona in 13 villages with a total area of the severe intensity of attacks. There have been attempted control measures with the release of natural enemies Tetratichus brontispae but not much success has be seen. This study aimed to find out: The dominant type of parasite in the district of Ende. T. brontispae were propagated and maintained in the laboratory using augmentation techniques, conservation or disposal was to be done. Colonies of the propagated parasite T. brontispae were then released in the field. The factors causing T. brontispae control failure, the population of B. longissima in the field, possibly the need for augmentation or conservation of T. brontispae and the right time to make the release of the parasite in the field was important. This research is expected to be useful as a basis in formulating and appropriate control program, in order to control the pest B. longissima in the field. The experiment was conducted from January to June 2010 at Nangakeo, Ndona and Ende district. Implementation of the research was divided into four stages: location survey, maintenance and multiplication of the pests B. longissima and T. brontispae parasite, parasite release and the evaluation of the result. The result was; that there are three types of parasites, B. longissima coconut leaf pest in Ende (sub Ndona, Nangakeo and Ende) the eggs of the parasite Trichogrammatoideanana spp., the larvae and pupae of the parasite Trichogrammatoideanana spp. and the ?Asecodeshispinarum Boucek?. T. brontispae parasite being the most dominant parasite in each district with 10% level of larvae and pupae of 60-90%, biased sex male : vemale ratio. The pest capability of T. brontispae parasite in the laboratory was 6: 10 with a success rate of 90 %. The decline in the influence of parasite performance was unsynchronized between phases from the phase of the insect host-parasite in the field, the availability of insect host and time of release as well as climatic conditions not being conductive.

This research conducted to know the biological responses of leaf miner parasitoid Liriomyza huidobrensis is Hemyptarsenus varicomis Girault (Eulophidae), Opius sp (Braconidae) and Gronotoma micromorpha (Eucoilidae). Three species of parasitoid chosen as the substance of research caused by biological agent superiorities. On this research, there are some observed that is long life imagoes, preoviposition, oviposition period, after oviposition, The egg-laying rate, fertilization, daily fertilization, mortality and female proportion. This research was conducted for four-month at Ecology Laboratory and Insect Systematics and at the Green House of Pest and Plant Diseases Department, Faculty of Agriculture Udayana University in Denpasar. Used substance of host kidney bean (Vigna sinensis L ) host insect ( L. Huidobrensis ) and species of the parasitoid (H.varicornis, Opius sp and G.micromorpha) The experiments using randomized complete block design was used in this research. The observed results indicated that betwen three species of parasitoid used H.varicornis has preoviposition period and time after oviposition shortest so that to reproduce generation of H.varicornis faster than G.micromopha and Opius sp. At the meantime the fertilization level, and best female proportion produced of H.varicornis. Mortality on G.micromorpha and O.liriomyzae cause of paralyzing and host- feeding by H.varicornis. Mortality on G.micromorpha and Opius sp influential to female proportion number that produced that is the mortality of female generation caused of paralyzing and host-feeding by H. varicornis, So that fertilizing level, parasitisation level and female proportion higher happen if G.micromorpha or Opius sp released after releasing H. varicornis
