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 income level of smallholder farmers can only meet their daily needs due to the location's remote location and the difficulty of communication access. Based on this, the Government seeks to formulate policies that are expected to have a real impact on increasing the productivity of smallholdings and improving the welfare of farmers. One of the efforts made is the Primary Member Cooperative Credit (KKPA). The purpose of this research is to examine the impact of the partnership program at the Windu Nabatindo Lestari (WNL) company in the KKPA scheme, a program to improve the welfare of plasma farmers. The research method is descriptive analysis with a qualitative approach using purposive sampling. Research respondents were 60 plasma farmers. Data collection techniques include field observations, in-depth interviews with questionnaires, and analysis of company documents. The results showed an increase in the welfare of plasma farmers after the partnership program. The partnership program at the Windu Nabatindo Lestari (WNL) company under the KKPA scheme positively impacts the welfare of plasma farmers in Pundu Village, Cempaga Hulu District East Kotawaringin, Central Kalimantan. The frequency of the number of plasma farmers who experienced increased income before and after the KKPA program was 83.3%.

Oil palm is agricultural that has excellent potential as a producer of vegetable oil globally, and oil palm plantations contribute to providing jobs for thousands of people in Indonesia. The greater a company, the more efficiency of work is needed. This research represents an effort to find a more efficient brondolanan transportation tool for workers in oil palm plantations. The study was conducted in May 2019 in two locations, the first location in Terusan Village, the second location in PT. Sinarmas, Manis Mata District, West Kalimantan. Data analysis uses descriptive analysis methods where the respondents of this study are employees of PT. Sinarmas as many as 30 people. The results showed that the utilization of tengkalang as a carrier brondolanan for workers in PT. Sinarmas is more effective and also more cost-effective. One unit has a lifespan of more than six months with a cost per unit of Rp. 20,000. While the black bucket per unit has a benefit period of three months with a cost per unit of Rp. 15,000. Then the result of cost analysis is calculated in one year, using tengkalang more efficiently by buying tengkalang Rp. 40.000 / year, while the black bucket purchase cost Rp. 60.000 / year. In addition, usingtengkalang means that the Company also participates in the welfare of surrounding communities to progress and grow together to improve the development of families and villages.
