<p><em>Oil palm plantations need fertilizers for optimum growth and production. However, excessive use of fertilizers can lead to pollution of groundwater. For this reason, a study was carried out to investigate groundwater quality of an oil palm ecosystem, which involved the measurement of 9-point monitor wells and run-off. This research was conducted in Kabun-Aliantan (N: 0002.925’ E: 100049.977’). Tandun, Riau-Indonesia. The location points of the monitored wells in this study comprised a young oil palm area (P1), an adult oil palm area near Lau river (P2), a housing complex at oil palm plantation (P3), an adult oil palm area at Marihat, Block A (P4), a housing 1 at the sub-district town (P5), a housing 2 at the sub-district town (P6), a cocoa area (P7), a village housing (P8), at the side of Lau river (PR), and a run-off in a micro catchment (N: 00027.936’ E: 100049, 977’). The parameters analyzed in the water samples were pH, nitrate-N (NO3</em><em>-</em><em>N), nitrite-N (NO2</em><em>-</em><em>N), ammonium-N (NH4-N), phosphate (P), potassium (K), calcium (Ca) and magnesium (Mg). </em></p><p><em>In general, pH, NO3</em><em>-</em><em>N, NO2</em><em>-</em><em>N, NH4-N, P, K, Ca and Mg increased after fertilizer application and decreased with time. All levels of parameters were lower than the WHO standard for drinking water. This study showed that the fertilizers on the oil palm plantation did not pollute the groundwater quality. However, groundwater pollution was found to be caused by residential wastes, such as the use of detergents and other human activities.</em></p>

The objectives of the research were to compare the quality of physical and chemical characteristics of the soils in the oil palm plantations applied with integrated farming system of cattle and oil palm plantation (IFSCO) and without IFSCO (non-IFSCO), as well as to evaluate the economic benefits of IFSCO application. The research was conducted in two oil palm plantations, i.e. an oil palm plantation applied with IFSCO (5 ha) and an oil palm plantation without IFSCO application (non-IFSCO) (5 ha), located in the Karya Makmur Village, Penawar Aji Subdistrict, Tulang Bawang District, Lampung, Indonesia, in June until August 2016. The research was conducted using a survey and systematic sampling methods to collect soil samples, and data from 30 farmers who applied IFSCO and other 30 farmers who applied non-IFSCO. The results showed that the application of organic fertilizer in the IFSCO field resulted in higher level of exchangeable-K, -Ca, -Mg, and -Na, cation exchange capacity (CEC), and organic-C content of the soil;and better improvement on the physical soil quality, i.e. bulk density, porosity and soil moisture content; in comparison to that in the field without organic fertilizer application (non-IFSCO field). However, the application of IFSCO did not affect the pH, available-P, base saturation and total-N content of the soil.  There was a difference in the texture class of the soils in the IFSCO field and non-IFSCO field.  The result of texture analysis showed that the texture of the soil in the IFSCO field is “clay”, while the texture of the soil in the non-IFSCO field is “sandy clay loam”.  Application of IFSCO can save the fertilizer cost by 66%, the feed cost by 50%, and can increase oil palm production and farmers’ income by about 25%, so it is economically profitable. Thus, IFSCO can improve soil quality and provide economic benefits for the farmers, so the IFSCO obviously supports the implementation of sustainable agriculture.

PTP.Nusantara-IV (Persero) especially in the Marjandi Gardens located in Panombean Panei, Simalungun Regency is an Indonesian state-owned enterprise engaged in the plantation sector, one of which is Oil Palm. Among the many oil palm plantation blocks, there are productive and unproductive oil palm plant blocks. Unproductive blocks affect the profits of Marjandi Gardens in the production of Palm Oil. Therefore, it is necessary to conduct research to find out the most productive and unproductive blocks of Oil Palm Plants. This study was conducted in Afdeling III Marjandi Gardens with oil palm planting years 2005 and 2006. The method used was the K-Means Clustering method, the blocks were divided into 2 Clusters namely High Clusters for the most productive blocks and Low Clusters for unproductive blocks. Based on the research that has been done, the results obtained are the number of 14 blocks of the most productive oil palm plants, namely (BM, BN, BO, BP, BR, BY, CE, CF, CK, CY, DE, DF, DG) and 26 blocks of plants Oil palm is unproductive, namely (BL, BQ, BS, BW, BX, BZ, CA, CB, CD, CG, CL, CM, CN, CO, CP, CQ, CR, CS, CW, CX, DA, DB, DC, DD). It is expected that the company can develop the most productive oil palm block so that the quality of the oil palm plant blocks is always maintained. As for the unproductive oil palm plant blocks, the company can make repairs to produce a productive block of oil palm in the future.

Excessive fertilizer applications in oil palm plantations are conventionally done to increase the oil yield, but they result in high production cost and environmental pollution. There have been only separate reports on the effects of fertilizer application on soil physical, chemical characteristics, and microbial biodiversity. Therefore, this study was conducted to determine the correlation between soil characteristics and soil microbial biodiversity in oil palm plantation after long-term frequent chemical fertilizer application compared with secondary soil, using molecular methods of polymerase chain reaction denaturing gradient gel electrophoresis (PCR-DGGE) and MiSeq. Secondary forest soil was chosen as the control. The results showed that after 25 years of fertilizer application, the total nitrogen and organic carbon contents decreased from low to very low scale, indicating soil infertility condition. Reduction of Firmicutes was related to suppression of soil borne diseases, and Bacteroidetes which is an indicator of soil health were both almost eliminated after 25 years of fertilizer application. In conclusion, long-term inorganic fertilizer application reduced the soil nitrogen, and organic carbon, altered beneficial microbes in the soil.

Fluctuation of quantity and quality of forage for ruminant animal is a problem of forage availability in Indonesia. Cover crop under oil palm plantation is potential sources of forage for ruminants but it has not been used effectively. This study was conducted to evaluate nutrients quality and estimated energy available of cover crop in dry season in Pelalawan regency, Riau. Seven years old oil palm plantation was plotted by randomized destructive sampling method. Nutrients composition include proximate, modified van soest fraction and protein association with cell wall (NDICP or ADICP) were analyzed for nutrient quality of cover crop. In vitro true dry matter digestibility (IVTDMD) and estimated energy available in cover crop were calculated from in vitro batch culture daisyII Ankom method. The result showed that cover crop is fresh forage energy feed because it contains more than 40% BK of TDN. Limited nutrient quality of cover crop is high contains of Lignin (22.4%BK). Value of IVTDMD of cover crop is 568.41 g/Kg DM with NDF digestibility 21.05% DM. In conclusion, cover crop under 7 years old oil palm plantation had enough nutrients quality for ruminant but it would be better for complete the data in wet season.Fluktuasi jumlah dan kualitas pakan hijauan untuk ternak ruminanasia adalah salah satu permasalahan penyediaannya di Indonesia.

The Relationship

Debt has been a common phenomenon in people’s lives, both in the big cities, as well as in remote areas. This debt activity has been internalized into people's lives so that it cannot be separated no matter how small. There are quite a number of existing related literatures that deal with this. However, debt is only seen as a means to meet the daily needs of debtors, in which the relationship between creditors and debtors is not far enough studied. The study related to the relationship between creditors and debtors (if any) is still limited. This article seeks to complement the existing literature by examining debt and credit cyrcle that create new relationships in the spectrum of oil palm plantation employees. This ethnographic study takes place in the housing complex of oil palm plantation employees in Kebun Sei Muara, Kalimantan Island. It involved 26 female informants consisting of six women workers, six housewives, and fourteen female traders. Data was collected using in-depth interview in order to explor the reasons for debt, reason for giving debt, the implication of debt, and how parties are related to debt. While participatory observation is carried out by participating in the daily activities of the Kebun Sei Muara community, such as shopping at a food stall, attending parties, helping in various parties, gossiping, social gathering, etc. The study indicates that debt has become the foundation of reciprocity relations in Kebun Sei Muara. This debt is carried out for from daily needs to the need for making life cycle parties, which involve not only the poor, but also rich people. This creates a reciprocal bond between the debtor and the creditor, the host and the guests, as well as creates balanced reciprocity between them. This relationship raises an obligation for both actors involved to give and return the contribution for the attending parties. In this context, there is a norm that requires them to come to provide contribution in the form of money and/or goods to the host, and expecting to have a balanced reciprocity in return. The higher the status, the bigger the party, the more debts the host make, and the return contribution will be used to pay for the debt. The higher the status, the more contribution the guests have to provide, though it depends on the closeness between the host and the guests, as well their previous contribution. Community members, who do not participate in the debt circle, will automatically be ostracized from social activities and are considered as “the others”. Conflict potentially occurs between debtor and creditor when payment is neglected, but this is depended on how the creditor responds to it. It is common, however, that this may be impacted on the future relationship not only between the two, but also with others in the Kebun Sei Muara.
