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

This research was conducted in Production Laboratory of Samarinda State Polytechnic of Agriculture. The research took 1 month for tool and material preparations, pesticide production, pesticide application, and data retrieval. There were three treatments i.e. P0 (without vegetable pesticide), P1 (vegetable pesticide made from the mixture of gamal leaf and tobacco leaf), and P2 (vegetable pesticide made out of soursop leaf. Each treatment was repeated five times. In the treatment, the leaves were soaked in the pesticide according to the prescription, the pesticide was then sprayed to the worm-infected-leaves in the jars before the jars were covered for seven days. This research aimed to know the how far the pesticide was effective in controlling the worm on banana leaves by observing the daily activity of the worm. Results show that P1 was the most effective pesticide since on day two after the application, it was visible that some worms have died.

Abstract

Silk sarong of Samarinda is a unique sarong made from silk threat imported from China. High quality mulberry plants are needed to support silkworm cultivation (sericulture). High quality mulberry plants are produced through in vitro propagation techniques. The aim of this research was to obtain mulberry leaves (Morus Sp) which are disease-free and uniform in order to produce high quality silk thread through sericulture technique in which the feed is multiplied in vitro. This research had four stages: sterilization, production of cultivation medium of Murashige and Skoog (MS), sub-culture, observation, and data analysis. The research was designed according toCompletely Randomized Design (RAL) with one factor i.e. different concentration of BAP (control, 0.5 mg/l, 1 mg/l, and 2 mg/l) and each treatment was replicated 8 times. The findings show that 2 mg/l treatment triggered rapid sprouting, produced the highest sprout and generated the most number of leaves. The application of BAP with different concentration also increased germination rate, the height of shoot, and the number of different sprout. All treatments were unsuccessful in inducing roots.

Abstract

Vinegar is one of the products that are often utilized by the community to enhance the taste of food. The purpose of this study was to determine the taste of vinegar with the addition of cinnamon and to determine the effect of long fermentation in the production of Neera vinegar. This research was completed by using randomized design with 2 factors, namely the long fermentation and fermentation type (aerobe and anaerobe). The results show that the highest water content was found in anaerobic fermentation with an average of 0.97%. The lower water content was in aerobic fermentation with an average of 0.96%. Since the high pH was at 2 days interval with pH 4, while the low pH was at day 6 that was with pH 3. The results of organoleptic tests for color showed the highest fermentation value on day 6 was with anaerobic fermentation with the average value of 3.70. The highest value of the organoleptic test for aroma was found in day 4 with anaerobic fermentation with an average of 3.60. The organoleptic test showed that anaerobic fermentation had the highest taste rate of 3.6 on average on day 6. Anaerobic fermentation process for 6 days resulted in pH value and organoleptic test preferred by panelists.

Abstract

The objective of this research was to study the utilization of mango seed to produce flour that serves multiple purposes. The study used various boiling time and drying temperature to produce mango seed flour with different qualities. The results indicate that treatment A1B1 produced the best mango seed flour based on the yield and organoleptic tests (15 minutes boiling time and 40oC drying temperature). A1B1 showed yield of 13.54%, water content of 6.72%, ash content of 2.57%, and color test of 3.02%

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.
