Abstract

Praktik pembuatan maket ini bertujuan untuk memberikan gambaran langsung kepada siswa-siswi SD Islamiyah Warungboto tentang ekosistem alam dengan cara dan metode yang sederhana.  Pelatihan di lakukan dalam tiga sesi. Sesi pertama diisi dengan penyampaian materi dasar ekosistem, berisi penyampaian sederhana tentang eksosistem alam seperti sawah, air, rumput, katak dan lingkungannya. Selanjutnya sesi ke dua diisi dengan praktik pembuatan maket ekosistem dengan alat dan bahan sederhana, dengan praktik siswa siswi mampu medapatkan langsung gambaran tentang ekosistem yang sesungguhnya di alam. Kemudian sesi ketiga adalah sesi yang di peruntukan bagi siswa-siswi SD Islamiyah Warungboto, Masing-masing kelompok maju ke depan untuk menjelaskan kepada teman kelas lainya tentang eksositem apa yang meraka buat maket, sehingga akan saling bertukar pengetahuan. Hasil pelatihan ini memberikan dampak yang baik kepada siswa-siswi SD Islamiyah Warungboto terhadap pengetahuan eksosistem alam, serta dapat meningkatkan kepedulian mereka terhadap lingkungan di sekitarnya.

Abstract

Work effectiveness is greatly influenced by organizational development, placement, and use of work. Productivity at work has a big impact on results. This study aims to identify the impact of determinants of labor productivity as an oil palm harvester in oil palm plantations in order to increase knowledge, skills and experience in work. Data on the labor productivity of oil palm harvest was carried out by Purpose sampling of 76 people taken from 6 stagnation in 3 afdeling related to wages and premiums obtained every month. Data analysis using descriptive methods and multiple linear regression. Multiple regression analysis partially shows that education level, number of dependents, and age have no real effect on labor productivity, but length of work does. Simultaneous regression tests show that education level, number of dependents, age, and length of working hours have a significant effect on the labor productivity of oil palm harvests.

Abstract

Hatch and carry is a breeding and distribution system for the primary pollinator of the oil palm, Elaeidobius kamerunicus. Information on the optimal distance for the Hatch and Carry application on pollination success and bunch productivity is still limited. This study aims to determine the effective distance of Hatch and Carry on fruit set and bunch weight in oil palm. The study used a quantitative method with a Completely Randomized Design (CRD), including Hatch and Carry distance treatments at radii of 10 m, 100 m, 200 m, 300 m, and 400 m, as well as assisted pollination techniques as a comparison. Data on fruit set and bunch weight were analyzed using analysis of variance (ANOVA) at the 95% confidence level, followed by the Duncan Multiple Range Test (DMRT). The results showed that the highest fruit set was observed at 10–200 m and was not significantly different, but decreased significantly at 300 m and 400 m. The same pattern also occurred for bunch weight, with the highest value at 100 m. The assisted pollination technique produces fruit set equivalent to the effective Hatch and Carry distance of 10–200 m. This study concluded that the effective distribution range of E. kamerunicus is within a radius of 200–300 m; thus, Hatch and Carry technology has the potential to be an efficient alternative for increasing oil palm productivity.
