Get PDFABSTRAKInsektisida kimia sintetis masih banyak digunakan kalangan petani untuk mengendalikan hama ulat grayak (Spodoptera frugiperda J.E Smith) yang menyerang tanaman jagung. Penggunaan insektisida kimia secara berlebihan menimbulkan pengaruh negatif bagi lingkungan dan kesehatan. Alternatif pengendalian S. frugiperda yang ramah lingkungan perlu dilakukan dengan memanfaatkan jamur entomopatogen, salah satunya berasal dari spesies Beauveria bassiana. Penelitian ini dilakukan untuk mengetahui tingkat kerapatan spora B. bassiana dan waktu aplikasi yang efektif terhadap mortalitas S. frugiperda pada tanaman jagung. Penelitian disusun secara rancangan acak lengkap (RAL) faktorial. Faktor pertama berupa kerapatan spora (106, 107, 108, dan 109 spora/ml), akuades steril dan insektisida kimia sintetis deltametrin sebagai kontrol. Faktor kedua adalah waktu aplikasi jamur (pagi dan sore hari). Hasil penelitian menunjukkan aplikasi B. bassiana pada waktu sore hari dengan kerapatan 108 dan 109 spora/ml mengakibatkan mortalitas larva S. frugiperda sebesar 60% dan 73.3%. Waktu aplikasi B. bassiana pada sore hari mengakibatkan persentase mortalitas lebih tinggi dibanding pada pagi hari. ABSTRACTSynthetic chemical insecticides are still widely used by farmers to control armyworm pests (Spodoptera frugiperda J.E Smith) which attack corn plants. Excessive use of chemical insecticides has negative effects on the environment and health. Environmentally friendly alternative control of S. frugiperda needs to be done by utilizing entomopathogenic fungi, one of which comes from the Beauveria bassiana species. This research was conducted to determine the density level of B. bassiana spores and the effective application time for S. frugiperda mortality on corn plants. The research was structured in a factorial Completely Randomized Design (CRD). The first factor was spore density (106, 107, 108, and 109 spores/ml), sterile distilled water and the synthetic chemical insecticide deltamethrin as a control. The second factor was the time of fungal application (morning and evening). The results show that application of B. bassiana in the afternoon with a density of 108 and 109 spores/ml resulted in S. frugiperda larvae mortality of 60% and 73.3%. The application time of B. bassiana in the afternoon resulted in a higher mortality percentage than in the morning
Pengelolaan Sumber Daya Alam Berbasis Transendensi Hukum Antara Pemerintah Daerah Dengan Masyarakat
Get PDFOne of the areas that has potential natural resources is Batu City with the nickname of the City of Agritourism. However, the penetration of economic capital has changed the identity of Batu City in such a way. Slowly but surely the natural beauty of this city began to be tarnished by the massive development of artificial tourism which had an impact on the natural ecosystem and also reduced the welfare and local wisdom of the community. Therefore, the purpose of this research is to offer a discourse on the purification of natural resource management policies through the Javanese spiritual concept of "Memayu Hayuning Bawana †which emphasizes the importance of protecting nature based on the nature of transcendence, namely the relationship between God, the universe and humans. This research is a normative (legal) research. The results of this study conclude: First, currently there has been an erosion of legal transcendence values in the management of natural resources in several regions including Batu City. This is characterized by the dominant role of the state (Government) in terms of natural resource management which is strongly motivated by the meanings of their rationality. This interpretation leads to exploitative actions that have a destructive impact on the environment. Second, seeing the fact of the massive exploitative actions against natural resources in Batu City, it is very important to purify natural resource management which is realized through a one-way relationship between the Regional Government and the Community based on the Javanese philosophical value of “Memayu Hayuning Bawanaâ€. This foundation becomes important in the philosophical-juridical-ecological frame to be used as the basis for any discussion of future natural resource management legal policies

Pembentukan Daerah Otonomi Baru: Pemekaran Provinsi Kepulauan Nias
Get PDFIndonesia adheres to the principle of decentralization in administering its government. Each region has the right and is given the authority to manage its own government affairs. The granting of broad autonomy to the regions is directed at accelerating the realization of social welfare through service improvement, community empowerment and participation. Law No. 23 of 2014 wants the birth of a new autonomous region in Indonesia. The implementation mechanism is further regulated in Government Regulation No. 78 of 2007. Expansion of regions is one of the efforts to accelerate national development. The conditions that must be met in the expansion of the new autonomous regions include: 1) basic territorial requirements; 2) regional capacity requirements; and 3) administrative requirements. The Nias Islands are an area that has been planned to be split into a new autonomous region. The research method used is empirical juridical, namely research conducted to analyze the implementation of legal norms that apply in society. Discussions regarding the plan for regional division of the Nias Islands have started since 2009 but until now there has been no realization from the central government. The obstacle to the expansion of the division is the existence of a moratorium set by the President. Regional expansion is also considered to be a burden on state finances considering that apart from the Nias Islands, there are still many other regions that have also proposed to do division. However, when an area meets the requirements for expansion as stipulated in Government Regulation No. 78 of 2007 and there is an urgency why the area must be divided immediately. It is better if the moratorium is lifted so that each region that has met the requirements to carry out expansion can become a new autonomous region and become more developed because it is given the authority to manage its own region
