Abstract

ABSTRAKMengetahui seberapa jauh aplikasi penggunaan ternak babi dalam kebun masyarakat Arfak di Pegunungan Arfak penting untuk dipelajari karena Arfak memiliki kondisi agroekologi penting. Masyarakat Arfak memiliki kearifan dalam bertani serta  memiliki hubungan yang dekat dengan ternak babi. Hasil tinjauan di lapang dan referensi menunjukkan bahwa ternak babi relatif masih digunakan pada lahan pertanian atau kebun keluarga masyarakat Arfak sebagai hewan penggembur tanah (soil dozer). Ternak babi, kebun dan masyarakat Arfak saling berinteraksi dengan memberikan peranan kepada masing-masing komponen. Kelebihan ternak babi sebagai penggembur tanah kebun biologis mampu membantu petani orang Arfak. Terdapat 7 keunggulan penggunaan ternak babi dalam kebun. Namun jumlah ternak yang dapat dimasukkan serta sejauhmana kinerja ternak babi dalam setiap luasan lahan secara ekonomis, ekologis dan sosiologis masih harus dikaji secara intensif. ABSTRACTKnowing how far the application of pig farming in Arfak people 's gardens in the Arfak Mountains is important to learn because Arfak has important agro ecological conditions, the Arfak people have wisdom in farming and have a close relationship with pigs. The results of the review in the field and references show that the pigs are relatively still used on agricultural land or Arfak people's family farms as soil dozers. Pigs and gardens and Arfak people interact with each other by providing service to each component. The advantages of pigs as biological gardeners are able to help Arfak farmers. There are 7 benefits of using pigs as bio-tillage inside Arfak household gardens. However, the number of livestock that can be included and the extent to which the performance of pigs in each area of land economically, ecologically and sociologically, must still be studied intensively.

Abstract

Common corn rust disease caused by the fungus Puccinia sorghi, causes small spots on the upper and lower surfaces of the leaves which then spread to the entire leaf surface, causing a decrease in photosynthetic yield. Losses due to this disease are 45-60%. This study aims to explore the resistance of corn varieties to rust disease. This research was arranged in a descriptive research design using 240 plants of corn. The maize varieties tested were Pertiwi 3, Betrass, Bissi 2, Bissi 18, Bima, and Prafi Merah varieties. The results showed that the intensity of disease increased continuously every week from the first appearance of 5 WAP to 11 WAP. At 11 WAP the severity of the disease was 76% Pertiwi 3, Betrass 91%, Bissi 2 82%, Bissi 18 89%, Bima 80% and Prafi Merah 92% so that all test varieties were classified as susceptible varieties. The susceptibility was triggered by the test variety's gene system which was not sufficient to inhibit the rate of development of pathogens with high virulence. In addition, weather factors with rainfall ranging between 73and 90%, adequate optimal temperatures ranging between 25.7oC and 28.8oC and heavy rains that occur continuously for 24-26 days strongly support production and sporadic distribution in the crop resulting in an increase in severity disease.

Abstract

The purpose of this study was to determine the distribution of the New Guinea flatworm (Platydemus manokwari) as a natural enemy of snails in the Manokwari area. Observations were made at 32 locations in Manokwari area used descriptive method with interviews and direct field observations. The results showed that the distribution of the New Guinea flatworm (P. manokwari) as a natural enemy of snails was found in all locations. However, these worms have not been found directly as biological control agents for snails.

Abstract

Preference is a form of statement that expresses feelings of preferring one thing over another. This study aimed to determine the preferences of snails (Achatina fulica) to several types of plants in the area of Manokwari. The method used in this research were descriptive method and field observation. Observations in the field were carried out by inventory of snails from the six plants, namely gedi, banana, papaya, sweet potato, cassava, and mustard greens, while data collection in the yard was carried out with an olfactometer to see the interest of snails in several types of plants. The results showed that snails liked the gedi plant the most while the least preferred was cassava.
