Buletin Loop of the Politeknik Pertanian Negeri Samarinda is one of the most active centres of scientific work in agriculture in the Samarinda. Problems are attacked from two distinct points of view: the economic, in which the object is to show how crops may be produced a little more cheaply than at present, and the scientific, the problem being investigated for the sake of the general principles it may bring out. Two sets of bulletins are therefore issued, the popular bulletin, intended for farmers, dealing mainly with local problems, and always from the local point of view, and the research bulletins. The popular bulletins are fully equal to any others in the United States, and much ahead of anything we publish here for farmers; in the series before us the subjects dealt with include land drainage, curing of seed corn, control of various weeds, draft-horse judging, a discussion of the methods of paying for milk at cheese factories, and so on. The research bulletins are the scientific papers of the staff; as usual in the Samarinda, each paper is published separately, and there is no common journal in which they all appear.

Abstract

Palm oil plantations are a strategic sector that plays a significant role in absorbing labor, particularly harvesters. Harvesters' income levels are a major factor influencing their families' well-being. This study aims to determine the income received by harvesters and analyze the level of family welfare of harvesters on oil palm plantations at PT. London Sumatra Indonesia Tbk, located in Tanjung Makmur Estate, East Kalimantan. The research method used was descriptive quantitative, with purposive sampling of six harvesters who met the research criteria. Data were obtained through interviews, observation, and documentation, then analyzed by comparing harvester income to the Regency/City Minimum Wage (UMK). The results showed that the average harvester income was Rp 4,674,565 per month, with a net income of Rp 3,673,124 per month after deducting Rp 732,860 per month for routine household costs and expenses covered by the company. Based on the Regency/City Minimum Wage (UMK) standard of Rp 3,711,017.82, the harvester income level was above the UMK and thus met the wage eligibility standard. This indicates that the harvester's income was able to meet basic family needs, leave some income for savings, and contribute positively to the welfare of the families of harvesters on oil palm plantations.

Abstract

Oil palm cultivation is not only carried out on flat land, but also in hilly areas with challenging topography. Proper plantation management, such as weed control, fertilization, and harvesting in accordance with standards, is essential to maintain quality and production yields. This study aims to (1) determine the differences in the productivity of chemical weed control workers on different plots of land (2) determine the factors that cause differences in the productivity of chemical weed control workers. The data analysis method was descriptive based on the results of field interviews, then using a productivity formula by comparing the number of hectares of work results with the working time for undulating slopes and steep slopes. The respondents in this study were five sprayers working in one of the blocks at PTPN IV Region V Longkali Plantation. The results show that there is a difference in the average productivity of chemical sprayers between the undulating slope class and the steep slope class. The average productivity in the undulating slope class is 0.126 ha/hour, while in the steep slope class it is 0.094 ha/hour. These data indicate that employee productivity is higher when working on land with undulating slopes than on steep slopes. In addition, there are several factors that cause differences in productivity, namely the level of terrain difficulty, water availability, psychology and motivation, topography, and weed conditions on the land.

Abstract

The knowledge of farming methods and various traditional agricultural tools owned by the ancestors of the people of East Kalimantan has been passed down to their descendants, remaining simple and used by a group of people from generation to generation, forming part of their technological system, according to their cultural conceptions. However, the current agricultural transformation in Samarinda shows a clear shift from traditional to modern farming systems, evident in the application of modern technology in agricultural activities. This study examines the transformation process, its driving factors, socio-economic impacts, and challenges and development strategies. Data were collected through literature review and interviews with local farmers. The results indicate that modern agriculture increases productivity and work efficiency, attracts younger generations, and supports food security in the region. However, limited land and access to technology are key challenges. The study concludes that agricultural modernization in Samarinda must be supported by inclusive policies that integrate technology, strengthen farmer institutions, and empower young people.

Abstract

Oil palm is a commodity with relatively high productivity compared to other plantation commodities. However, increasing the scale of oil palm farming is not always in line with improving farmers' welfare. Some of the factors that are suspected of influencing include high production costs, unstable selling prices of FFB that do not benefit farmers, limited market access, and weaknesses in farming management and management. This study aims to analyze the production costs, receipts, and income of farmers who are members of the Padaelo Farmers Group. The research was carried out for 4 months with a case study approach and descriptive quantitative methods. The sampling technique uses a saturated census, which is as many as 25 people. The data consists of primary and secondary data. The average area of oil palm land owned by farmers is 1.64 ha/person with a plant age of 18 years. The average production reaches 645 kg/ha/one harvest and the selling price is Rp1,800 /kg. The results of the study show that in one harvest, the production cost incurred by farmers reaches Rp327,482/ha and the income obtained is Rp1,161,000/ha, so that the income received is Rp833,518/ha.

Abstract

Black orchids are a renowned germplasm source in East Kalimantan. However, their habitat is becoming increasingly scarce due to slow cultivation, necessitating rapid and precise propagation methods, such as tissue culture. Subculture is a key component of tissue culture. The purpose of this study was to determine the growth response of black orchid on MS growing media with the addition of foliar fertilizer and natural extracts.  This research was conducted at the Tissue Culture Laboratory, Faculty of Mathematics and Natural Sciences, Mulawarman University. The study period was three months, from March to June 2025. This study used a non-factorial Completely Randomized Design (CRD). Three treatment levels, each level consisting of eight replications: S0 (control), S1 (MS Media + leaf fertilizer), S2 (MS Media + natural extract). Data were analyzed for diversity using Analysis of Variance (ANOVA) with an α level of 5% and then Duncan's Multiple Range Test (DMRT) with an α level of 5%. The results showed that all three treatments significantly affected all observed variables. The addition of leaf fertilizer to MS media produced the best response in terms of shoot emergence time and shoot number. The addition of natural extract to MS media produced the best response in terms of leaf number.

Abstract

This study examines the characteristics of water absorption and load-bearing resistance of coconut coir–based cocopot with different thicknesses as an environmentally friendly planting medium. Cocopots were produced from a mixture of cocofiber, cocopeat, and latex adhesive with three thickness variations: 1.0 cm, 1.5 cm, and 2.0 cm. Water absorption was evaluated using a 5-minute immersion test, while load-bearing resistance was assessed by repeatedly dropping soil-filled cocopots from a height of 3 meters under a total load of 1,096 g. The results show a consistent trend indicating that increased thickness is associated with higher water absorption capacity and improved mechanical durability. Cocopots with a thickness of 2.0 cm exhibited the highest water absorption (90–91%) and the lowest damage level, with a Load-Bearing Resistance Index of 0.55–0.58%. In contrast, cocopots with a thickness of 1.0 cm showed the lowest performance. These findings suggest that thicker cocopots provide better functional characteristics for agricultural applications.

Abstract

Kirinyuh (Chromolaena odorata L.) is a shrub weed commonly found in open land, with the potential to be used as compost material. However, in the composting process, obstacles arise due to the high cellulose content in the kirinyuh stems. Therefore, a decomposer is needed to help break down the cellulose in the kirinyuh stems. One decomposer with the ability to break down quickly is the Black Soldier Fly (BSF) larvae, commonly known as maggots. The aim of this study is to determine the duration of compost production with the addition of maggots and to compare the results with the standard compost. The research was conducted from June to September 2024. The study consists of two treatments: P0, which is without maggots (control), and P1, which is treated with 5 grams of maggots. The results of the study show that in treatment P0, the compost was ready for use on day 21, while in treatment P1, it was ready on day 18. According to its element content, the compost produced from treatment P1 was better than that from treatment P0. Treatment P1 met the compost standards, while treatment P0 did not meet the standards, especially in terms of potassium (K).
