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.

Oryctes rhinoceros or Rhino beetle ( Coleoptera; Scarabidae) is a major pest in oil palm plantations. This pest is very harmful, especially in replanting areas, and young plants cause up to 25 per cent of palm oil-related deaths. This study aims to evaluate the effectiveness of integrated pest management in suppressing the population and development of O. rhinoceros. The research was conducted at the Oil Palm Plantation, PT. Sumber Indah Perkasa, Penawartama, Tulangbawang Regency, Lampung Provincial for one year. The analysis used is a descriptive analysis involving the collection of data from a variety of control techniques. The results showed that the pest control techniques of O. rhinoceros lightrap, ferotrap, holetrap, nets, larval quotes and chemistry could suppress or decrease pest populations. The control with light traps is very efficient because it obtained the number of captures of imago beetles up to 246,224 in 1 year. The integrated pest control of O. rhinoceros successfully reduced the attack of beetles until it did not reach the economic threshold. It is hoped that implementing integrated O. rhinoceros pest control can be a reference for plantations

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.

Fertilization Effectiveness on the Productivity of Fresh Fruit Bunches and Maintenance Costs of Oil Palm Aji, Wandha Atmaka; Utami, Aditya Dyah; Nugroho, Bagus; Toyyibah, Toyyibah; Nurcahya, Mukti Ahmad

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

The study aims to calculate the income and added value of businesses that process liberica coffee fruit into ground coffee. This survey lasted for one month, from August 2020 to September 2020. The research place is the KBA Coffee Shop owned by Mr. Sutrisno in South Arut District. The method taken in this study is to use primary data and secondary data. Primary data were obtained through live interviews using a series of questions. Secondary data were obtained through supporting literature and their relation to this study. The data analysis methods used in this study are: (1) calculating the business income of liberica coffee fruit processed into coffee grounds, (2) calculating the added value of liberica coffee grounds. The results of the study showed that the Liberica coffee ground processing business provided income to Mr. Sutrisno of Rp. 2 million. 17,991,111.13 per month. The added value enjoyed by KBA coffee shop owners is Rp. 22,830 / Kg of raw materials used. This added value is what KBA Coffee Shop obtains when using 1 kg of raw materials.

The productivity management of oil palm plantations is carried out by analyzing various influencing factors, but the growing conditions of oil palms are one of the causes of fluctuations in oil palm production. This paper aims to identify post-harvest increases in oil palm productivity. Productivity depends on the number of clusters and the weight of fresh fruit bunches (FFB) produced yearly. The methods of this study were conducted using a targeted sampling technique using available production data for plant time points from 4 to 13 years of age. The total plant sample was 636 ha in Central Kalimantan. As a result, plant growth factors can significantly impact oil palm productivity as measured by the components of oil palm plant production: fresh bunch production per hectare, average bunch weight, and the number of oil palm bunches. FFB tonnage and mean bunch weight increase each year from age 3 to age 13, according to a quadratic regression pattern, whereas the number of palm clusters, in contrast, decreases in number with increasing plant age. This study was intended to serve as a reference and source of information for making production decisions for oil palm plantations to achieve optimal results.
