Good faith is fundamentals in every contract, without which a contract will find it difficult to achieve its goals. In 2019, through a contract made before a notary in the hall of Kampar Regent Office, Kooperasi Nenek Eno Senamanenek and PT. Perkebunan Nusantara IV start a new beginning after a long period of dispute over Senamanenek community’s customary land. The good faith in fulfillment of contract between KNES and PTPN V would affect the legal relationship between these two parties. For KNES, the realization of the clauses within the contract will affect senamanenek community who become the member of the cooperative. The contract object was a palm oil plantation owned by the cooperative member. This empirical legal study scrutinized the implementation of good faith in the contract between KNES and PTPN V By identifying the law and the effectiveness of legal principles in the community. It took place in Kampar Regency. Primary, secondary, and tertiary data were collected through interviews and literature review. This study concludes that the good faith has not been fully implemented in the contract between PTPN V and KNES due to legal and non-legal factors. Therefore, both parties are suggested to possess a good faith in all stages of the contract-making process, from the pre-contract, contract, and post-contract stages. They are also suggested to minimize factors inhibiting good faith in the contract.

The research aimed to analyze the implementation of the principle of transparency by the National Land Agency to access cultivation rights title documents in the plantation sector. It is empirical legal research. It was conducted at the Office of the National Land Agency of Gorontalo district, Gorontalo province, Indonesia. The results show that the principle of transparency of cultivation right title by the National Land Agency had yet to be implemented as instructed by the judge in the Decision of Supreme Court No. 121 K/TUN/2017. It is caused by the consideration of the National Land Agency that the document of right cultivation title is included in an undisclosed document; hence, if it is public, it violates the company's privacy provisions and applicable regulations. The implementation of the principle of transparency by the National Land Agency to access cultivation right title documents in the plantation sector have yet to be effective because it is influenced by the attitude of professionalism of the National Land Agency, which exercises its duties as applicable regulations.

One environmental service provided by A. crassicarpa plantation is extrafloral nectar which has been widely used for beekeeping since 2019. Nevertheless, nowadays between apiaries practiced unfair competition since there were price fall led by oversupply and low demand after covid pandemic ended. Thus, evaluating the cost structure, profitability, and its feasibility value are critically required. The study's objectives were to 1) evaluate cost structure, revenue and profitability and 2) to conduct a feasibility analysis of each apiary type. This study was conducted from in 2019 to 2022 at the Siak Regency, Riau, Indonesia. Structure interviews combined with desk studies were carried out to collect the data. Data were analyzed based on cost structure, revenue, profitability, and feasibility analysis. All types of apiaries were feasible since they could cover variable and fixed costs. However, it revealed that all types of apiaries experienced minus in profitability in the fourth of financial year. In general, variable cost relatively increased to the level of 50% of total cost in the fourth year. In contrast, fixed cost was relatively declined to less than 50%. Apiaries managed two rits had a better performance in cost structure to face the competitive market followed by apiaries managed three rit. Meanwhile, apiaries managed rit one experienced such a difficult challenge to survive.

The study explores the narrative of oil palm expansion in the Marind-Anim area, where the land and its natural surroundings are not empty spaces without meaning but an eternal identity that is preserved because it tells the historical relationship between local people and their ancestors. Owning land, even the smallest parcel, can enhance self-esteem and social security. This study traces the narrative of oil palm expansion in the Marind-Anim areas and examines the encounter between the indigenous Marind-Anim community and the global economic forces. This local-global intersection is examined using an ethnographic approach with data collected through in-depth interviews, observations, and Focus Group Discussions (FGD). The results show that the function of sago land as an economic foundation is decreasing due to the global economic pressures from the monoculture oil palm plantations. On the one hand, the Marind-Anim indigenous land has become a frontier area for global economic expansion aiming to supply the global food demand. On the other hand, the sago plantation as a safety valve for the traditional economy and local food security has been reduced by oil palm plantations.

Coffee cultivation in Indonesia generally only relies on rainfall as a source of water. Drought that occurs in the dry season inhibits growth, reduces yields, and even death of plants. Not all plants are equally resistant to drought conditions. Drought-resistant coffee clones usually develop several resistance mechanisms, including the formation of specific compounds to protect cells and tissues from damage caused by drought stress. Therefore, the objective of this study was to investigate the influence of watering interval on the seedling growth of three clones of Arabica coffee. This study used applying intervals of watering every two, four and six days as first factor and three Arabica coffee clones as second factor, namely Andungsari 2K, S 795, and Andungsari 1. The experimental design used a factorial completely randomized design where every treatment combination had three replications. This study on Arabica coffee nursery lasted for three months. Results obtained in this study demonstrated that combination of watering every four and six days on Andungsari 2K clone had the best values on several observed variables. Number of stomata, leaf thickness, fresh root weight, and root dry weight were larger for watering every six days on the Andungsari 2K clone, meanwhile leaf number, stem diameter, fresh and dry weight of leaves were larger for watering every four days on Andungsari 2K clone. This study showed that there was an interaction between watering intervals and Arabica coffee clones on plant growth. Treatment combination of watering every six and four days on Andungsari 2K clone significantly affect number of stomata, fresh root weight, and root dry weight especially for watering every six days on Andungsari 2K clone.

Abstract The Indonesia plantation law does not regulate in detail about the plantation profit sharing system, so the legal certainty is questionable. In addition, the agreement in principle of Islam (musaqah) needs to be implemented considering that most of the people involved in this activity are Muslim. Furthermore, people are usually making agreements only based on trust and agreement without a written agreement and there is no deadline for the expiration of the agreement so that often occurring a controversy. The type of this research is a normative juridical research, using the statute approach method and other related regulations. The analytical method used in this research is descriptive analysis method. The results showed that the plantation profit sharing system in Indonesia did not have legal certainty. The agreement on trust and agreement without a written agreement is allowed based on positive and Islamic law. The absence of the date line of agreement base on positive law is allowed because there are no regulations that regulate it, but in Islamic law is not allowed because it is gharar. Abstrak Dalam undang-undang perkebunan tidak mengatur secara rinci mengenai sistem bagi hasil perkebunan sehingga perlu dipertanyakan mengenai kepastian hukumnya. Selain itu perjanjian secara prinsip Islam (akad musaqah) perlu diterapkan mengingat sebagian besar yang terlibat dalam kegiatan ini ada masyarakat muslim. Masyarakat terbiasa melakukan perjanjian hanya atas dasar kepercayaan dan kesepakatan saja tanpa adanya perjanjian tertulis serta tidak adanya batas waktu berakhirnya perjanjian sehingga kerap terjadi sengketa. Rumusan masalah dalam penelitian ini adalah bagaimana hakikat sistem pelaksanaan perjanjian bagi hasil penggarapan lahan perkebunan di Indonesia menurut perspektif hukum positif dan hukum Islam. Jenis Penelitian ini adalah penelitian yuridis normatif, dengan menggunakan metode pendekatan perundang-undangan serta peraturan terkait. Metode analisis yang digunakan dalam penelitian ini adalah metode deskriptif analisis. Hasil penelitian menunjukkan bahwa sistem bagi hasil perkebunan di Indonesia belum memiliki kepastian hukum. Mengenai perjanjian atas kepercayaan dan kesepakatan tanpa adanya perjanjian tertulis sah menurut hukum positif dan hukum Islam. Mengenai tidak adanya batas waktu perjanjian sah menurut hukum positif karena memang belum ada peraturan yang mengatur akan tetapi tidak sah menurut hukum Islam karena tidak sesuai dengan syarat akad musaqah yang mengharuskan adanya batas waktu agar terhindar dari gharar.

This research was conducted to: 1) analyze the contribution of female worker income to household income, and 2) analyze the factors that influence the female worker income of plantation female workers at P.T. Agro Muko (Mukomuko Estate). The number of female workers at P.T. Agro Muko (Mukomuko Estate) was 297. Therefore, by using the Slovin formula, the counted number respondents was 75. The contribution of female worker’s income to household income was counted with the percentage of female worker’s income contribution to the total of household income. Meanwhile, the factors that influenced to the income of female worker was analyzed using multiple linear regression model. The results indicate that the average income of female worker is Rp 1,481,680/month with an average contribution of 55.17% to household income. Female worker ages and husband’s income had negative effect on the female worker income, while formal education, number of family dependents, and working experience had positive effect. Other family member’s income had no effect.

Nationally, the program to rejuvenate oil palm has become a concern of the Government. It is supported by the policy of replanting grant funds using funds from the Oil Palm Plantation Fund Management Agency (BPDPKS), including West Sumatra Province. In Dharmasraya District, KUD Suka Maju received grant funds to realize replanting in 2019, while KUD Bukit Jaya was for realization in 2020. This paper describes the activities' results to the two KUDs in preparation for replanting oil palm using BPDPKS funds. The activity's objective is to encourage and revive the spirit of cooperation in the KUD and help accelerate the effective coordination among stakeholders in the replanting program in the district of Dharmasraya. In the context of broader regional development, particularly the development of sustainable oil palm plantations, this oil palm replanting program needs to involve stakeholders from the initial planning stages to implementation and evaluation. Coordination between related government agencies requires the participation of the Regional Development Planning Agency (Bappeda) as the coordinator of regional planning, and it is necessary to internalize the replanting program plan with all its aspects into the Office's Strategic Plan (Renstra) and the Regional Medium-Term Development Plan.

Termites are social insects that play an important role in ecosystem. Habitat is a crucial factors determining diversity of termites. IPB University campus has quite diverse habitat types. In this research, we study the diversity and abundance of termite species around IPB University campus. Two methods used for data collection, i.e. baiting system with pine wood and transect survey within 10 x 10 m area. Six species of termites found belongs to two families, Termitidae (Macrotermes gilvus, Odontotermes javanicus, Microtermes insperatus, and Capritermes mohri) and Rhinotermitidae (Schedorhinotermes javanicus and Coptotermes curvignathus). The most diverse with the high abundance of these termites are found in the rubber trees area, Faculty of Fisheries (FPI) and the forest behind the main administration building, Rectorate (REK) because this area provides an abundant source of cellulose as a food source for termites. While the building areas tend to have a lower diversity and abundance index because food sources for termites are not always available due to human activities. Non-metric multidimensional scaling analysis shows that the termites species composition is different between study area.

This study aims to determine the effect of production, land area, and labor on the Farmer Exchange Rate of the smallholder plantation crops subsector individually or partially and the effect of production, land area, and labor simultaneously on the Farmer Exchange Rate in North Maluku Province in 2014 -2018. The object of this study was the farmers of North Maluku Province because the agricultural sector plays an important role and contributes greatly to the economy in North Maluku Province. This study was conducted in January-May 2020. The data collected and processed in this study are data within 5 years. The population in this study was all data on the Farmer Exchange Rate, agricultural production, agricultural land area, and labor in North Maluku Province in 2014-2018. The data used in this study were secondary data obtained from the Central Agency on Statistics of North Maluku Province in 2020 and other literature related to this study. The test tool used is multiple linear regression analysis, and the analytical tool used was IBM SPSS Statistics 16.0 software. The results showed that partially production did not affect the Farmer Exchange Rate of smallholder plantation crops in North Maluku province. Partially, land areas affect the Farmer Exchange Rate of smallholder plantation crops in North Maluku province. Individually or partially, the labor did not affect the Farmer Exchange Rate of smallholder plantation crops in North Maluku province. Simultaneously or overall, production, land area, and labor affect the Farmer Exchange Rate of smallholder plantation crops in North Maluku province, it can be said that it will affect the farmer welfare.

Spiders are crucial in controlling insect pest population. The various cultivation managements such as fertilizer and pesticide application, weeding, pruning, harvesting, and cropping system affect their diversity. In the plantation, vegetation diversification has applied various practices, including monoculture, and intercropping, which influence the spider community. Thus, this study was intended to determine the spider abundance and diversity of the tea plantation, and the intercropping field (tea and strawberry) at Serang village, Karangreja Sub-District, District of Purbalingga. A survey and purposive sampling techniques were conducted, then the spiders were hand collected. Shannon-Wiener diversity (H’), Evenness (E), Simpson’s dominance (D), and Sorensen’s similarity (IS) indices were used to measure the spider diversity. The results revealed a total number of 575 individual spiders from 10 families, i.e., Araneae, Araneidae, Clubionidae, Linyphiidae, Lycosidae, Nephilidae, Oxyopidae, Salticidae, Tetragnathidae, Theridiidae, and Thomisidae. Araneidae was the most abundant in both fields. The total abundance of spiders in tea plantation (379 individuals), however, was greater than that in the intercropping field (196 individuals). Shannon-Wiener diversity reached H’= 1.873 in the plantation, and H’= 1.975 in the intercropping field.

Peat swamp forest is an important pool of terrestrial carbon stock (C-stock). Therefore, research on change of C-stock and its economic value of peat swamp forest conversion to pulpwood industrial plantation forest is important. The objectives of this research are to know the change of C-stock on peat swamp forest conversion to pulpwood industrial plantation forest, and to get the carbon economic value of peat swamp forest and pulpwood industrial plantation forest. The result showed that conversion from logged over and secondary forest causing the decrease of C-stocks of 103.53 and 61.02 t ha-1 year-1, while conversion from degraded forest causing the increase of C-stocks of 22.47 t ha-1 year-1. REDD project on pulpwood industrial plantation forest from degraded land causing the increase of NPV of 20.21% and 51.13% for compensation prices US$ 9 and 12 tCO2-e-1. REDD project with conservation on secondary forest gave lower economic value than pulpwood industrial plantation forest at all compensation prices simulation, and REDD project with preservation logging gave higher economic value than pulpwood industrial plantation forest at compensation price US$ 12 tCO2-e-1. REDD project on logged over forest gave higher economic value than pulpwood plantation at compensation prices US$ 9 and 12 tCO2-e-1 (both on conservation and preservation logging scenarios).
