Medicinal plants have been very important plants that are responsible in maintaining the health of millions of people in the world since a very long time. Planting these crops must be carried out on a land that is suitable based on the results of a land suitability evaluation. A framework to evaluate the land suitability for many land uses is initiated by Food and Agricultural Organization (FAO) in the late 1970’s. As the advent of smart phone nowadays becoming ubiquitous technology to solve problems in most settings, such as education, agriculture, medicine, psychology, and many others. This paper is to capitalize such advantage by converting the framework into a mobile app. This solution is hoped to help land users or planners to be more effective and efficient in evaluating their land. An algorithm is employed in the form the Rule Based System (RBS) in a way to construct the framework into bunch of rules that connect each other, resulting the conclusion of suitability. The rules itself are working on some variables, namely annual rainfall, altitude, drainage, soils’ type, pH, flood risk, fertility of the soils, soil solumn depth, etc. This study focuses on three medicinal crops only, which are candlenut, cardamom and onion to be evaluated. Data of agro climatic that were determining the suitability of the crops were developed into general and specific criteria for the plants. A usability model was studied from 40 respondents using the app. It is found that the usability of the app was in “very good” classification, with dimension scores, ranging from 3.79 and 4.22.

Industrial Forest Plantations (IFP) are intended to increase the productivity non-productive natural forest production. In South Sumatra Province IFP is widely developed in wetlands; one of them is in acid sulphate soils which have major problems with flooding and waterlogging. To solve this problem, the technology other than making drainage canals is Bed Raising. Bed Raising is to make beds to facilitate the implementation of planting, maintenance and harvesting, in addition to maintaining good soil aeration conditions. However, Bed Raising on acid sulphate soil raises a new problem is pirite oxidation, which affects the chemical properties of acidic sulphate soil. The purpose of this study was to see the benefits of bed raising in the management of acid sulphate land in IFP areas. This study uses survey methods and data are presented in tabulations. The results of this study indicate that the benefits of bed raising in the management of acid sulphate land are no longer flooded or waterlogging. While the results of chemical analysis of soil in bed raising plots are very acidic soil pH (pH <3), Al-dd saturation is very high (> 70%), and high pyrite concentration (> 2.4%). This value is not suitable for plant growth.

Conflicts in forest areas usually occur due to unclear rights or laws relating to the tenure system. This can happen between individuals, communities, government agencies or private sector. The boundaries of forest areas that have not been agreed upon by the community and the government also trigger conflict. The reality in the field shows that the land in the forest area has been used by the community or the surrounding population, both migrants and local residents, but the existence of these communities has not been accommodated, especially in forestry development planning. The development of industrial timber plantations (in Indonesian – “hutan tanaman industri”, HTI) and plantations on a large scale has different backgrounds. The development of industrial plantations (HTI) is motivated more by the emergence of a large number of unproductive production forests and incentives that attract the private sector. Government policies concerning forest conversion and land use as well as various investment ease packages encourage growth in the sector's development. This study aims to determine the dynamics of the conflict, and the mediation of forestry cooperation agreements as a process of resolving the conflict of production forest area holders of PT Bumi Mekar Hijau's license and Riding Village community in Pangkalan Lampam sub-district, Ogan Komering Ilir Regency. This study uses a method qualitative research with descriptive data presentation. Qualitative methods in this study are defined as research procedures that produce description data in the form of written or oral words from people and observed behavior. The aim is to explain the phenomena of collecting data in depth. The population and sampling in qualitative research are very limited. With population limitations and sampling, the data collected must be in-depth and can explain the phenomenon under study. Here more emphasized is the issue of the depth of data quality. Data analysis was carried out by means of an inherent analysis of each aspect of the forest concession conflict case found. The analysis is also based on the existing conflict themes in accordance with the results of the interpretation of the cases found. In this case, the analysis process can take place since the data collection process is carried out. By state law, the area is part of the business license for utilization of plantations in industrial plantations (IUPHHK-HTI) PT. Bumi Mekar Hijau. But at that time, the company opened production forests in the region. The new activity is only canal digging and land clearing. The Riding Village Dusun I and II occupied an area of around 10,000 hectares because they felt that the company and the government had never asked their permission to make land an industrial plantation. The community has evidence that the land belongs to their ancestors, namely “sonor” (planting rice) and trenches for timber by their ancestors in the region. This physical evidence is a source of community power to survive claiming the area. In July 2013, the people of Riding Village and PT. Bumi Mekar Hijau agreed to resolve land conflicts through an open, concrete and successful dialogue process. Both parties appointed Wahana Bumi Hijau (WBH) and Imparsial Mediator Networking (IMN) as mediators who assisted the negotiation process. Since the mediation process has taken place it has been very difficult for both parties to agree on what was delivered and there is no point of completion. But on March 16, 2017 the MoU on conflict peace in Desa Riding with PT. Bumi Mekar Hijau was held at the Forestry Service of South Sumatra Province which was attended by the Village Government and Riding community, Tripika Sub-District Pangkalan Lampam, IMN Mediator, Asia Pulp and Paper (APP), Forest Service District Ogan Komering Ilir District, South Sumatra Provincial Forestry Service, Directorate of handling tenure and customary forest conflicts and Director of Sustainable Production Forest Management. On April 21, 2017, the signing of a forestry cooperation agreement between PT. Bumi Mekar Hijau with Riding Village was held, in Riding Village with an area of 10,000 hectares, which was intended for 3,500 hectares of acacia plant partnerships, 1500 hectares of wana tani (Agroforestry) partnerships, 610 hectares for drainage infrastructure, 333.6 hectares for residential settlements, 1,000.8 hectares for government-owned road infrastructure, 1,863.4 hectares of forage buffalo land and 1,192.2 hectares of protected area.

One of the concrete efforts made by the Indonesian government is through social forestry policy as a trigger for land conflicts. One area that has implemented a pattern of social forestry is a forest area located in the management area of the Regional Technical Implementation Unit(UPTD) KPHRegion I Meranti located in Musi Banyuasin Regency. Only 3 social forestry scheme permits have been issued. So the aims of this study was to find out and analyze the process of implementing social forestry policy and analyze the factors that influence. The study was conducted in Pangkalan Bulian and Lubuk Bintialo Villages, Batang Hari Leko District, Musi Banyuasin Regency, South Sumatra Province. Used descriptive method combined (mixed methods) from two different approaches namely quantitative or qualitative approaches. Funding and staff resources (human resources) are still lacking. The process of collective action between actors is running well with the existence of a committed PPS Working Group. Technical rules are clear with the existence of SOPs that are derived from the rules of government and local government.Communication goes well between communities (Forest farmer groups and cooperative members) - local government and facilitators, but not so well between government structures (village heads and apparatus and local government.The Social forestry policy in Musi Banyuasin District, South Sumatra has been effectively implemented from the perspective of policy accuracy in resolving forestry problems and environmental accuracy in accepting policies.

Palm oil has become a major edible and economic commodity with applications in various domestic and industrial processes. Malaysia is the second largest producer and exporter of crude palm oil (CPO). The oil palm industry in Malaysia significantly expanded and has become a major economic sector. The global demand of this precious commodity as food and fuel has caused a significant upsurge in production of oil palm. A tremendous increase of CPO production has been witnessed in the Malaysian oil palm industry over a decade now. The CPO production in 2011 was about 11.8 million tonnes but skyrocketed to 19.92 million tonnes in 2017. Beyond the revenue generation from the oil palm industry in Malaysia, there is significant investment in research and development that has resulted in the discovery of more sustainable ways to manage oil palm waste. This overview therefore seeks to evaluate the trend in crude palm oil production in Malaysia and its economic contribution to the nation from 2007-2017. Various indices associated with crude palm oil production such as planted land area, volume of exported CPO, revenue generated from the exported CPO, average annual price of exported CPO, fresh fruit yield and oil extraction rate was discussed. This overview is limited to crude palm oil production within 2007-2017 and seeks to discuss the trend within the context of the timeframe.

Publisher : Program Pascasarjana Universitas Sriwijaya

This research was conducted to treat rubber industry wastewater by using fly-ash as an adsorbent and hybrid membrane UF-RO to produce clean water. In this research was analyzed the effect of flow rate of wastewater treatment to remove turbidity, zinc, and iron. The applied flow rate of membrane separation was of 7 L/min and 14 L/min and the operation time was of 90 min respectively. The rejection concentration of turbidity, zinc, and iron decreased with increasing the flow rate at adsorbent fly-ash. Whereas at the hybrid membrane UF-RO, the rejection concentration of turbidity, zinc, and iron increased with increasing the flow rate. The maximum rejection of turbidity was 24.26%, 95%, and 67.89% for adsorbent fly-ash, UF membrane, and RO membrane respectively. The maximum rejection of zinc was 91.67%, 59.70%, and 14.81% for adsorbent fly-ash, UF membrane, and RO membrane respectively. The maximum rejection of iron was 62.24% and 21.62% for adsorbent fly-ash, UF membrane respectively. The pollutants concentration in the permeate was met the quality standards of the Indonesian health department through the decision of the Minister of Health number 907 of 2002 concerning supervision of the quality of drinking water.
