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

Local microorganisms (MOL) are microorganism that are used as bio activators in the producing solid and liquid organic fertilizer. The main components of local microorganism are carbohydrates, glucose, and microorganism sources. The research was conducted based on two reasons: (1) the fact that many fruit waste was left unused, for instance, deserted banana sticks, golden snail which considered as a pest to crops, cattle rumen, and (2) the need to reduce dependability on anorganic fertilizer by exploring the role of microorganism. The objective of this research was to produce mol liquid which can be used as bio activator as well as liquid organic fertilizer. The materials used in this production were banana sticks, fruit waste, golden snail, cow rumen, cow urine, coconut water, rice water (lery), shrimp paste, brown sugar for MOL I. MOL II used the same materials except for brown sugar which was substituted with white sugar. MOL was produced through fermentation. The production of MOL was done in the Production Laboratory at State Agricultural Polytechnic of Samarinda. Based on the observation, the combination of MOL was well fermented on day ten. This was shown by dark brown color, stablized temperature, tape smell, and the sight of thin fibre on the mol surface.

Abstract

The quantity of garbage accumulated in the cities from time to time is increasing that it has become difficult to manage as it is associated with not only hygiene but also disposal issues. Thus it is necessary to conduct a research to discover the right method in managing household waste into liquied organic fertilizer. Not only the fertilizer will reduce the quantity of garbage, it also can be applied to cacao plants. The goal of this research was to analyze the impact of liquid organic fertilizer made out of household waste on the growth of cocoa seeds. Completely randomized design with four treatments and ten replication were used. Treatment 1 (P1) wasthe control; treatment 2 (P2) was 15 cc liquid organic fertilizer/liter water; treatment 3 (P3) was 25 cc liquid organic fertilizer/liter water; and treatment 4 (P4) was 35 cc liquid organic fertilizer/liter water. The results indicate that the application of liquid organic fertilizer was not significant on all parameter tested (the number of leaves, height of plant and diameter of cocoa seed). Out of all parameters tested, P3 showed the highest score while P0 the lowest.

Abstract

Midrib palm oil leaves which often stacked around palm oil trees have been underused by the society. The leaves have the potencial to be used as a bokashi material. The high number of leaves wasted during harvesting has instigated the utilization of the leaves. There were three treatments in this research: P1 (25 kg midrib and leaves + 6 kg chicken manure + 1 kg bran + 200 ml EM-4 + 20 l water + 2 kg palm sugar), P2 (25 kg midrib and leaves + 8 kg chicken manure + 2 kg bran + 300 ml EM-4 + 30 l water + 3 kg palm sugar), P3 (25 kg midrib and leaves + 10 kg chicken manure + 3 kg bran + 400 ml EM-4 + 40 l water + 4 kg palm sugar). In this research, the temperature, colour, smell, testure, pH, and time needed for bokashi to form were observed. The findings show that P2, P3, and P1 gave the best results on all parameters observed. P2 required 44 days, P3 49 days, and P1 52 days to form bokashi. Based on the colour, smell, and texture, P2, P3, and P1 have transformed into compost fertlizer on day req 35, 40, and 43 respectively. In regard to standar, P1 with COrganic of 29.96 and C/N ratio of 9.46 and P3 with C-Organic of 31.30 and C/N Ratio of 9.54 meet the Standard of Organic Fertilizer Quality based on Regulation of Minister of Agricultureno. 70 / Permentan / SR.140 / 10/2011.
