Weeds are one of the problems that must be overcome in soybean cultivation. The use of organic mulch with planting distance is a solution to the problem of weeds, besides that both can also improve the quality of production as expected. The purpose of the study was to determine the effect of organic mulch and plant spacing, and the interaction between the two factors regarding the growth and yield of soybean production. The design used was a 3 x 3 factorial pattern Randomized group design with 3 replications. The variables studied were organic mulch and plant spacing. The organic mulch factor consisted of 3 levels: control, water hyacinth and rice straw. The spacing is 40 cm x 10 cm, 40 cm x 20 cm and 40 cm x 30 cm and 3 levels are the factors. The observed variables were plant height rate, number of seeds per plant, seed weight per plant and dry seed yield. The results of the variance test stated that organic mulch affected the rate of plant height, number of seeds per plant, seed weight per plant and dry seed weight. The use of rice straw mulch can increase the rate of plant height, seed weight per plant, number of seeds per plant, and dry seed yield of soybean. Plant Spacing affects the number of seeds per plant, seed weight per plant and dry seed yield. The variable number of seeds per plant, the variable seed weight, and the variable dry seed yield can increase in the 40 cm x 30 cm spacing treatment. There is no interaction between organic mulch and plant spacing on soybean growth and yield.

This research uses quantitative methods. The purpose of this study was to determine the effect of self-esteem and intellectual intelligence on student learning resilience. The population is 120 students and a sample of 60 is taken using a random sampling technique. The results showed that there was a significant positive effect of self-esteem on student learning resilience, where the coefficient rx1y = 0.539 with p = 0.000, which means the better self-esteem, the better learning resilience. The coefficient of r squared self-esteem with the dependent variable learning resilience is r2 = 0.439. This shows that learning resilience is formed by self-esteem with a contribution of 32.30%. The intellectual intelligence variable has a significant positive effect on learning resilience where the coefficient rx2y = 0.290 with p = 0.000, this means that the better intellectual intelligence, the better learning resilience. The r-squared coefficient of intellectual intelligence on the dependent variable of learning resilience is r2 = 0.401. This shows that learning resilience is formed by intellectual intelligence of 11.60%. The variables of self-esteem and intellectual intelligence have a significant positive effect in simulation on learning resilience where the coefficient r = 0.439; with p = 0.000 means p < 0.010. The determinant coefficient (r2) of the influence of self-esteem and intellectual intelligence on learning resilience is r2 = 0.439. This shows that resilience is formed by self esteem and intellectual intelligence together with a contribution of 43.90%.

Turbin angin sumbu vertikal atau VAWT (Vertical Axis Wind Turbine) merupakan turbin angin yang memiliki struktur mekanik tegak ke atas dengan bilah-bilah turbin yang berputar terhadap sumbu-z tegak lurus. Berdasark an hasil eksperimen diperoleh bahwa terdapat hubungan antara kecepatan putaran turbin yang memutar generator dengan keluaran tegangan dan daya yang dihasilkan, sehingga diperlukan upaya mengendalikan kecepatan turbin angin agar dapat berputar sesuai setpoin yang ingin dicapai. Kontribusi dari penelitian ini berupa pengembangan sistem kontrol berbasis logika Fuzzy untuk mengendalikan kecepatan turbin VAWT dengan hanya menggunakan umpan balik berupa kecepatan turbin angin. Hal ini berbeda dengan penelitian sebelumnya dimana kecepatan angin dan keluaran daya dijadikan sebagai umpan balik. Untuk mengetahui karakteristik dari kecepatan turbin dan keluaran tegangan, serta hubungan antara kecepatan turbin dan kecepatan angin dengan variasi sudut pitch bilah, maka pengujian dilakukan dalam skala laboratorium dengan menggunakan blower. Untuk merancang rule base (aturan) Fuzzy, maka karakteristik dari respon turbin angin terhadap kecepatan angin diteliti terlebih dahulu. Kemudian kontroller berbasis logika Fuzzy dibuat dan diimplementasikan. Untuk menguji efektivitas kontroller Fuzzy yang dibuat, maka implementasi dilakukan pada turbin VAWT sedangkan simulasi diterapkan pada model PMSG turbin angin melalui Simulink/Matlab. Berdasarkan hasil pengujian melalui simulasi dan eksperimen dengan mengukur kinerja respon sistem kontrol menggunakan Integral Absolut Error (IAE) untuk masing-masing nilai setpoin kecepatan turbin (35, 45, 85, dan 100 RPM) diperoleh bahwa untuk nilai setpoin kecil maka nilai IAE akan semakin besar dibandingkan setpoin yang lebih tinggi. Persentase nilai rata-rata IAE untuk simulasi adalah 10,25% lebih tinggi dibandingkan dengan eksperimen. Hal ini kemudian menunjukkan bahwa pengendalian kecepatan turbin pada kecepatan rendah relatif lebih sulit dibandingkan dengan kecepatan turbin lebih tinggi.

Gouramy (Osphronemus gouramy Lac.) is one of the original fish from Indonesia that lives in fresh water and has high economic value because of its dense texture, high nutrition, and delicious taste so that it is widely favored by Indonesians. The results of juvenile cultivation activities have not been going well so far, this is because the growth of gouramy’s juvenile is slower than the growth of other freshwater fish’s juvenile. One alternative that can increase the growth and protein content of gouramy juvenile is to utilize of the availability of lamtoro seeds. The purpose of this study was to determine the effect of feeding lamtoro seed fermentation on growth and protein content of gouramy’s juvenile. This study used experimental method with a completely randomized design (CRD with 6 treatments and 4 replications). Data were analyzed using Analysis of Variance Test (ANOVA) and further test in the form of Honest Significant Difference (Tukey HSD Test) at the 95% confidence level. The results showed that P3 with the addition of fermented lamtoro seed flour 40% can increase the growth and protein content of gouramy juvenile. The conclusion of this study was lamtoro seed fermented feed has effect in increasing growth and protein content of gouramy’s juvenile.
