Abstract

This study aims to determine the business feasibility of pine resin (Pinus merkusii Jungh et de Vriese) at protected forest management unit or KPHL Kulawi and determine the effect of increasing the cost of managing pine resin on business feasibility through sensitivity analysis. The value of input and output at the time of the study was considered as a constant price with units of costs and revenues generated in units of Rp/Ha/Year. The analysis was carried out using the formula of investment feasibility criteria namely Net Present Value (NPV), Benefit Cost Ratio (BCR), Internal Rate of Return (IRR) and sensitivity analysis to determine the strength of the business in the event of increased costs. This study uses Bank Indonesia's annual average interest rate of 6.75%, obtained NPV value of Rp.296.870.072,20, BCR value is greater than 1 (one) that is 2.23 and large IRR value is 39,63%, which is greater than the investment interest rate. Based on the investment eligibility criteria, the pine sap business fulfils the feasible requirements to run. The results of the sensitivity analysis show the pine sap business in the Kulawi KPHL is not strong in facing a 120% increase in costs, an NPV value < 0 and a BCR value decrease below zero, which means that the pine sap investment is not feasible to continue.

Abstract

Increased rice production carried out by rice cultivation in dry land faces constraints of vulnerability to climate change, especially drought that can reduce production. This study aims to determine the results of some local upland rice cultivars and also their tolerance to drought stress. The study was conducted at the green house, Faculty of Agriculture, Tadulako University, Palu, from September 2018 to February 2019. This research was an experimental design research with a completely randomized design (RAL) factorial pattern. The first factor is the cultivar (K) of rice consisting of 4 namely Taku Rice, Uva Rice, Jahara Rice and Delima Rice. The second factor is drought stress (C) in the form of water supply based on field capacity consisting of four treatment levels of 100%, 85%, 70% and C3: 55%. The treatment of drought stress resulted in an increase in the percentage of empty grains, a decrease in the number of panicle grains and crop yields. The highest crop yields found in Delima rice cultivars were significantly different from Jahara rice but not significantly different from Taku and Uva rice. This is in line with the stress sensitivity index where Jahara rice is indicated to be vulnerable to drought stress.

Abstract

Many parties have an interest in forest resources in Central Sulawesi. Some are in line with or against the conservation goals. In the context of preservation of Central Sulawesi Forest Park, it is necessary to take joint action in formulating policies, harmonizing the interests of the community and the management of Central Sulawesi. This research aims to identify the role of stakeholder in the management and utilization of forest Resources in Forest Park, analyze problem and formulate collaborative patterns of conflict resolution. The research was conducted in Januari-March 2019. The research applied data collection techniques through interviews with respondents taken by purposive sampling method, including those who had an interest in managing Forest Park, Ngatabaru Village community, Ngatabaru Village government, field officers and the parties of Forest Park Regional Technical Executing Unit. Data analysis used the matrix of influence and interests Reedet al, (2009), classifies stakeholders into key players, context setters, subject and crowd. The stakeholder analysismodel with three stages of stakeholder identification, stakeholder classification, and describing stakeholder relationships. The results show that 12 stakeholder had different levels of influence and interst in the management and utilization in Forest Park. There are 4 stakeholder groups in (key player), 2 stakeholders (Subject), 4 stakeholders (Context Setter), and 2 stakeholder (Crowd). The level of stakeholder relations has the opportunity to establish cooperation. But the actual relationship between stakeholder in the management of Central Sulawesi tends to be weak. The results of data analysis show that there is a problem of lack of synchronization and coordination. With this, it is necessary to realize a pattern of collaboration that has high importance in the Central Sulawesi Forest Park area. Building a shared vision unites different viewpoints of those who agree, respect each other, and provide benefits so that sustainable and sustainable management of Central Sulawesi will be achieved.

Abstract

Food crops are agricultural products consumed to support our daily lives. Food plants are also a source of vitamins and minerals needed by our bodies and directly play a role in improving health. Therefore, the hygiene and safety of the food we consume is very important, not to cause health problems. Soil is an importantfactor in agriculture, as a medium to grow plants and is also a part of the cycle of heavy metals. The gold mining business is often seen as the cause of environmental damage and pollution. This research was conducted at food and secondary crops farms around Poboya, where soil and plant analysis was carried out at the Laboratory of Natural Resources and Environment, Faculty of Agriculture, Tadulako University, Palu. The research was conducted from September to November 2020. The method used was survey with field observations and laboratory analysis, gradually done through pre-survey, main survey (sampling) and laboratory analysis with tactical sampling. The results showed that mercury (Hg) concentration in the sample point 1 was 0.48 - 0.52 ppm, sample point 2 was 0.62 - 0.63 ppm, sample point 3 was 0.30 - 0.35 ppm and sample point 4 is 0.25 - 0.26 ppm. While the concentration of mercury (Hg) in food crops, namely: sample point 1 is 0.31 - 0.33 ppm, sample point 2 is 0.45 - 0.48 ppm, sample point 3 is between 0.20 - 0.24 ppm and sample point 4 around 0.09 - 0.10 ppm. This shows that the content of heavy metal mercury (Hg) in the soil around Poboya has passed the tolerable threshold. Meanwhile, the concentration of mercury (Hg) in food crops at points 1 and 2 passed the critical threshold, while sample points 3 and 4 were still below the critical threshold. The farther the distance from the processing site, the less mercury content in the soil and in food crops.
