In the world of education there is now an electronic-based learning system that can be used for distance learning. The change in learning from the manual base to electronic precisely the internet indicates a global change to make it easier for humans to interact without having to meet. In the field of computers today we also find many companies in the company, the market and the world of education, including schools, have used information systems based on automation. With the aim of facilitating the processing of data and information can be obtained quickly and accurately. One way to provide good, fast and safe service is a trusted and proven system that is able to provide librarian officers with an open source SLIMS application. SLIMS is an application library that is almost perfect for organizing data data and information needed.

Riau Province is one of the provinces in Sumatra with the most oil palm plantations. Riau Province was once recognized as Indonesia’s greatest oil-producing province, but with the fall in output owing to decreasing oil reserves, Riau has become a greater palm oil producer. Not unexpectedly, palm oil has surpassed petroleum in terms of foreign exchange in Indonesia since 2010. There are numerous stages in this research, namely problem analysis, data collection, data preprocessing, single exponential smoothing prediction, data modeling, and calculation precision. Based on the findings of the testing, the Single Exponential Smoothing technique with alpha 0.9 may be used to forecast the requirement for prior time series data in the future, particularly in the case of oil palm output in Riau Province. Oil palm production is expected to grow somewhat over the next five years, according to the forecast.

Pondok Pesantren Ibnu Al-Mubarok is an Islamic Education Institution located on Jl. Sri Palas, Rumbai Hill, Kec. Rumbai, Pekanbaru City, Riau.

Sycanus annulicornis is an important predator for palm leaf-eating caterpillars (UPDKS) from the Limacodidae family. Therefore, these predators need to be propagated and disseminated in the area of ​​oil palm plantations so that they can become a mortality factor in biological control (UPDKS). Predator S. annulicornis is a predator that is very useful for controlling caterpillar pests in oil palm plantations. His ability to prey on fire caterpillars in the field, as well as his short life cycle and high reproductive ability make this predator very potential to be applied in fire caterpillar pest control. This research was carried out at Sycanus House Afdeling V Tanah Raja PT. Perkebunan Nusantara III Serdang Bedagai North Sumatra. The time of the study was carried out in August - September 2018. The results showed that fire caterpillar (Setothosea asigna) was able to be controlled by predators (Sycanus annulicornis) in F1 treatment (1 Sycanus annulicornis), F2 (2 Sycanus annulicornis) and F3 on the first day after application, the highest mortality seen in the treatment F3 (3 Sycanus annulicornis).

Today's technology continues to grow rapidly which can be used to facilitate and support human activities, starting from the homework, business, marketing and office processes. So it takes knowledge to use technology-based facilities to improve human resources that are efficient for life independence. With the development of the world of digitalization technology is becoming evident before humans of this era, where in the past people for shopping and learning must come to the intended destination, but now people only stay at home or anywhere they can do their activities with just the touch of a finger. The ease of this facility is inseparable from the many Android-based applications to market products to be sold, both changing services, goods, and personnel. The condition of changing activities hard to soft activities is because the development of the digital era is very important for students to understand the development and training of Android-based applications in order to gain skills in designing Android-based applications open souce namely with an inventor app that can be used free of charge, its form visuals that make it easier for students to design and create android-based applications.
