The high number of cases of dengue fever in Indonesia, so it needs to be held vector control effort. Moringa is used as a natural anti-mosquito capable of supplying larvae. This is because there are compounds of steroids, triterpenoids, alkaloids, saponins, flavanoids, and tannins in the stem of moringa. The type of research used was experimental with post test only control group design method. The data were collected by counting the number of Aedes aegypti instar III larvae that died in each type of salinity concentration during the exposure time. The experiment was conducted 4 times, Observation, calculation and recording of the number of live and dead larvae every 24, 32, 40 and 48 hours after treatment. The data that has been collected and analyzed is then presented in tabular and narrative form. At the concentration of 3% in the Moringa leather bark estrants at the time of 24 hour measurements in each treatment of 1 (3), 2, 3, 3 (3) treatment, 4 (1) treatment with an average percentage of larva death 27 , 5%. The concentration of 3% extract of Moringa leaf bark effectively kills Aedes aegepty larvae by 45% within 48 hours. Concentration of 3.5% extract of Moringa leaf bark effectively kills Aedes aegepty larva by 45% within 24 hours. The concentration of 4% extract of Moringa leaf bark effectively kills Aedes aegepty larva by 67.5% within 24 hours. The effective exposure time of 24 hours resulted in the death of 67.5% Aedes aegypti.

Latar Belakang. Diabetes melitus (DM) adalah penyakit metabolik dengan karakteristik hiperglikemia yang terjadi karena kelainan sekresi insulin, kerja insulin, atau kedua-duanya. Penyakit ini dilaporkan terjadi pada 9% laki-laki dan 7,9% wanita. Laporan Center of disease control (CDC) menyebutkan tahun 2014 terdapat 8,1 juta orang tidak terdiagnosa DM dan 29,1 juta mengalami penyakit ini di Amerika Serikat. Pada penderita diabetes dapat terjadi kerusakan jangka panjang, disfungsi, dan kegagalan organ yang berbeda, terutama mata (diabetes retinopathy), ginjal (nefropati diabetik), saraf (neuropati diabetes), jantung (infark miokard) dan pembuluh darah (aterosklerosis) dan infertilitas. Laporan insiden infertilitas terkait DM terjadi pada 9% orang dewasa berusia >18 tahun mengalami akibat difungsi endokrin spermatogenesis. Vitamin E berperan sebagai antioksidan eksogen (non-enzimatis) yang dapat melindungi kerusakan membran biologis akibat radikal bebas. Vitamin E melindungi asam lemak tidak jenuh pada membran fosfolipid. Secara partikular, vitamin E juga penting dalam mencegah peroksidasi membran asam lemak tak jenuh. Metode. Penelitian ini adalah penelitian eksperimental dengan menggunakan rancangan post-test only control group design secara laboratorium eksperimental. Rancangan penelitian ini dipilih berdasarkan konsep bahwa setiap unit dari populasi adalah homogen dan memiliki karakteristik yang sama. Pembagian sampel dilakukan secaraacak (random assignment). Pada kelompok eksperimen perlakuanlangsung diberikan stimulus dan pengamatan akhir sementara pada kelompok kontrol digunakan sebagai pembanding dari kelompok perlakuan. Hasil. Rata-rata diamater tubulus seminiferus testes tikus pada masing-masing kelompok perlakuan menunjukkan angka yang bervariasi. Rata-rata diamater tubulus seminiferus testes tikus pada perlakuan kontrol negatif (KN) adalah 261,57± 5,72 μm, kemudian mengalami penurunan menjadi 241,18 ± 18,53 μm, pada perlakuan tikus DM yang  diinduksi aloksan (KP),  dan mengalami peningkatan kembali pada perlakuan tikus DM yang dinduksi aloksan dan vitamin E dengan dosis 100 mg/kgbb/hari (P1), dan 200 mg/kgbb/hari (P2), secara berturut-turut adalah 265,92 ± 15,97 μm dan 271,41 ± 24,79 μm. Kesimpulan. Berdasarkan uji statistik Analysis of variance (ANOVA) one way didapatkan nilai signifikannya p 0,039 <0,05, maka dapat ditarik kesimpulan bahwa perlakuan pemberian vitamin E (P1 dan P2) berpengaruh secara signifikan terhadap diameter tubulus seminiferus testis tikus putih diabetes.

Research on tree-type irrigation pipe networks is an important component of agricultural water-saving projects. The optimal design of tree-type irrigation pipe networks is a key aspect regarding the profitability of irrigated agriculture. Meanwhile, swarm intelligence optimization algorithms have good computational ability and can be applied to solve many optimization problems in agricultural engineering. To identify the lowest investment cost for a pipe network, this study defined the concept of an upper water node to ensure the connectivity of tree-type irrigation pipe networks, and therefore, improve the pipe network planning model without using preliminary network connection diagrams. In addition, this study proposed an improved chicken swarm optimization algorithm (Improved Chicken Swarm Optimization using Adaptive Search and Variation, ICSO-ASV), which was applied to solve 12 test functions of different dimensions. The test results show that, compared to the traditional chicken swarm algorithm and other algorithms in the control group, the ICSO-ASV algorithm could effectively improve the global search capability. Finally, the ICSO-ASV algorithm was used to plan and design 15-node and 40-node pipe networks. The calculation results show that the average investment costs of the two pipe networks generated by the ICSO-ASV algorithm were 42.20% and 31.09% lower than those generated by the traditional chicken swarm algorithm, which further verified the feasibility of applying ICSO-ASV to design tree-type irrigation pipe networks. Thus, the design method proposed in this study can solve the optimal problems of tree-type irrigation pipe networks with varying topologies. The optimal solutions can be generated automatically using the ICSO-ASV algorithm if essential parameters of the pipe network planning model are provided.

Background: It is necessary to investigate the performances of the optimized tree-type cylindrical-shaped nanoporous filtering membranes with 3 or 5 branch pores in each pore tree. Objective: To explore the design method for and the performances of the liquid-particle and liquidliquid separations of the optimized tree-type cylindrical-shaped nanoporous filtering membranes with 3 or 5 branch pores in each pore tree. Methods: The analysis was made for the flow resistance of the studied membrane based on the nanoscale flow equation. The optimum ratios of the radius of the trunk pore to the radius of the branch pore were typically calculated for yielding the lowest flow resistance of this membrane. The capability of the liquid-liquid separation of this membrane was investigated by exploring the flow resistances of this membrane for different liquids. Results: The optimum ratios of the radius of the trunk pore to the radius of the branch pore were typically calculated for the maximum fluxes of these membranes for different passing liquid-pore wall interactions. They can be used for the design of the studied membranes for liquid-particle or liquid-liquid separations. The flow resistances of the studied membranes in the optimum condition for different liquids were also calculated, and the capability of the liquid-liquid separation of the membranes is evidenced. Conclusion: The obtained results can be used for the design of the studied membranes for achieving their optimum operating condition, by taking the ratio of the radius of the trunk pore to the radius of the branch pore as optimum. The studied membranes also have good capabilities of liquid-liquid separations if the mixed liquids have greatly different interactions with the pore wall and the radius of the branch pore is below 3nm or less.
