One of the determining factors for water availability for palm oil plants that do not use irrigation systems is rainfall. The availability of water is a major factor that limits the level of production of palm oil plants. The availability of water for oil palm plants in the field is obtained from rainfall data. This research was conducted at PT. Menthobi Makmur Lestari, Lamandau Regency, Central Kalimantan Province, from June 2021 to July 2021. This study uses secondary data analysis including data on of fresh fruit bunches (TBS) production components in the form of components of the number of fruit bunchesg, average fruit bunches weight, number of productive principals, seed fruit bunches weight; data on the production of fres TBS; rainfall data; and monthly rainy day data in 2017, 2018 and 2019 in 6 Divisions. The results of the analysis showed that variable rainfall and rainy days had a real effect on the increase in TBS production at the age of 5 years. Correlation results in plants aged 12, 15 and 18 years with a two-way analysis at the test level of 1% showed the variable rainfall and rainy day had a strong, real and unidirectional relationship. The correlation value of rainfall and consecutive rainy days is 0.892; 0,887; and 0.855 with significance value of 0.000.

The productivity of oil palm is highly dependent on the application of fertilization. Fertilizer applications must pay attention to its effectiveness and efficiency so that nutrients are absorbed optimally at the right time and right dosage. This research was conducted to assess the effectiveness of fertilization time. In addition, this also aimed to examine the effectiveness of oil palm fertilization which affects the productivity of fresh fruit bunches (FFB) and increases the production income. The data used were secondary data including fertilization and productivity of FFB at time intervals after fertilization for 6, 7, and 8 months in Kujan Estate Division, PT Menthobi Makmur Lestari (MMaL), Kujan Village, Nanga Bulik District, Lamandau, Central Kalimantan Province. The data obtained were analyzed using MS software. Excel was also employed to describe the dosage and time applied for 1 year and the productivity of FFB after 6 months of fertilization. Fertilizer application in months with high rainfall and long dry season is less effective and efficient for nutrient availability. The productivity of FFB in the second semester after 6 months of fertilization has increased compared to the first semester. The effective application of fertilizers can increase the production of CPO and reduce the total maintenance cost of the oil palm company

SD Islamiyah merupakan salah satu sekolah dasar yang berada di Warungboto, Kotamadya Yogyakarta. SD Islamiyah memiliki siswa total 40 peserta didik. Permasalahan yang dihadapi di SD Islamiyah adalah minimnya penyuluhan tentang kesehatan diri dan lingkungan.
