Abstract

Coal mining is a significant contributor to the economy of East Kalimantan Province, with most activities employing open-pit mining systems involving stripping and transporting soil surface. If not properly managed, these activities can lead to Acid Mine Drainage (AMD), which is rainwater and groundwater reacting with sulfide content. Without any treatment before discharge into the environment, AMD can cause environmental pollution. One such treatment method is constructed wetlands, utilizing Pontederia crassipes to absorb heavy metals present in AMD. This study aims to determine the phytoremediation effect on the pH and TSS of acid mine drainage using constructed wetland methods. The research was conducted at PT. Lanna Harita Indonesia, using three 60x50x50 cm container boxes as a collection pond for AMD, a phytoremediation pond containing sand, zeolite rock, and filter cotton, and a constructed wetland phytoremediation pond containing Pontederia crassipes. The results show that Pontederia crassipes can increase the acidic pH from 4.11 to 7.65 and reduce the TSS value from 1016 mg/L to 22 mg/L. This indicates that the final AMD values after phytoremediation treatment comply with the quality standards outlined in East Kalimantan Regional Regulation No. 2 of 2011, meaning it is suitable for discharge into the environment with minimal negative environmental impact.

Abstract

Employee performance is an important aspect of achieving optimal productivity for the company. Providing salaries and premiums is one of the factors believed to affect employee performance. This study aims to determine the effect of salary and premium on the performance of oil palm harvesting employees in Afdeling 2 PT Citra Agro Kencana. The research method used is a quantitative approach with multiple linear regression analysis techniques. The sample in this study amounted to 40 respondents taken through the saturated sampling method. Data were collected through questionnaires and interviews, and processed using the SPSS Version 22 application. The results showed that salary partially had a positive and significant effect on employee performance, while premiums had no significant effect on employee performance. However, simultaneously, salary and premiums have a significant effect on the performance of harvesting employees. This study concludes that providing proper and timely salaries can improve employee performance, while the premium system needs to be evaluated to be more transparent and fair in its implementation.

Abstract

Cocoa (Theobrama cacao L.) is one of the plantation products that has a very high economic value. Cocoa productivity has decreased every year. In 2019, cocoa productivity in Indonesia was 734,795 thousand tons and has decreased every year until 2022, cocoa productivity was 650,612 thousand tons. To overcome this, plant rejuvenation and provision of superior planting materials are needed. One common propagation technique is stem cuttings, which is growing new plants from parts of the parent plant. The success of propagation through cuttings is highly dependent on the ability of the cuttings to grow roots, a process that can be enhanced by administering plant growth regulators, especially those from the auxin group. This study aims to evaluate the effect of natural plant growth regulator (PGR) concentrations on clonal stem cuttings of Plagiotropic Cocoa (PCC) Sulawesi 01. The experiment was conducted from August 2024 to January 2025 at the Jember State Polytechnic. The non-factorial Randomized Complete Block Design (RBD) used was P0 (control), P1 to P4 (long bean sprout extract concentrations of 20%, 40%, 60%, and 80%, respectively), and P5 to P8 (coconut water concentrations of 20%, 40%, 60%, and 80%, respectively). Each treatment was repeated three times, with two experimental samples per replication. The results showed that the administration of natural ZPT at the highest coconut water concentration (80%, P8) significantly increased shoot height at 90, 120, and 150 days after planting (DAP), as well as root length at 150 DAP, compared to other treatments.

Abstract

Cocoa (Theobroma cacao L.) is a key plantation commodity, with Indonesia being one of the world's largest producers. This study aimed to evaluate the effect of shallot (Allium ascalonicum L.) extract concentrations as a natural plant growth regulator on the vegetative growth of cocoa cuttings derived from Orthotropic Shoot Cocoa (OSC) of Sulawesi Clone 01. The research was conducted from August 2024 to January 2025 at the Seed Technology Laboratory Nursery, Jember State Polytechnic. A non-factorial Randomized Complete Block Design (RCBD) was used, consisting of five treatments: 0% (control), 25%, 50%, 75%, and 100% shallot extract concentrations, each with five replications. Observed parameters included survival percentage, shoot height, and dry biomass weight. The results showed that shallot extract had no significant effect on the survival percentage of cuttings. However, it had a significant to highly significant effect on shoot height at 60, 90, 120, and 150 days after planting (DAP), and on dry biomass weight. The best vegetative growth was observed at 100% concentration (BM4), followed by 75% (BM3). This suggests that the auxin and nutrient content in shallot extract can enhance cell metabolism and growth, thereby supporting better shoot development and biomass accumulation. In conclusion, shallot extract has potential as an organic plant growth regulator to improve cocoa cutting performance, particularly at concentrations between 75% and 100%

Abstract

Motivation is one of the crucial factors that drive individuals to perform optimally, including harvesters who play a vital role in the plantation sector productivity. Harvesting work often involves physically demanding challenges, changing working conditions, and production targets, so their level of motivation greatly affects the efficiency and quality of the harvest. Understanding the categories of work motivation that underlie the enthusiasm of these workers is essential for improving their well-being and ultimately, contributing to sustainability and success of the plantation business as a whole. Objectives of this study are to identify the characteristics of harvesters, measure the categories of work motivation among harvesters, and calculate the productivity of harvesters. This study uses a sample from one population of harvesters at Afdeling 5, Senyiur Estate and employs questionnaires as the data collection tool. Respondent selection technique used a census method, which includes all 30 members of the population. Results show that the highest percentage of harvesters are aged between 31-40 years old (40%), have a primary school education (93%), and have worked for 3-4 years (43%). Work motivation category of harvesters is characterized as ‘very good’. Average productivity of harvesters was shown at 104 bunches/MD, exceeding the company's determined basis (80 bunches/MD).
