Abstract

This research aims to study and determine the level of full maturity and the appropriate and best drying time for nutmeg mace so that a high yield of mace oil is produced with physico-chemical properties that meet Buenther's criteria. Ripe nutmeg will produce good quality nutmeg and mace when used as spices for export. Apart from that, old nutmeg mace can still be used for its essential oil because the oil content is still quite high. To get nutmeg oil from the fruit when it is young, you can also get mace which has a high level of oil content. The water content in mace is quite high so it is easy for mold to grow and will affect the oil yield and possibly also the physico-chemical properties of the oil. This research is a factorial experiment using a Completely Randomized Design (CRD) consisting of two factors. Factor A, namely the maturity level of mace, consists of two levels, namely full young and old mace. Factor B is the drying time of mace with four levels, namely 0, 8,16 and 24 hours. Each treatment was repeated three times. The oven drying temperature was 40° C and distillation was carried out for 20 hours. The results of the research for each level of mace maturity gave significant differences to the yield, specific gravity, refractive index, optical rotation and acid number of the refined oil, while the length of drying of the mace gave a real difference to the physico-chemical properties of the mace oil. The best results obtained were young mace which was dried for 24 hours with the following characteristics, full water content of 6.77%, mace oil yield of 12.8889 ml/100 grams of material, specific gravity of mace oil 0.9255; full oil refractive index 1.4871; The optical rotation of the oil is (+) 6.3433 and the acid number of mace oil is 2.29.

Abstract

Many coconut husks in coconut-producing área have not been maximally utilized, especially on a small scale for farmers. It happened due to the difficulty of obtaining simple small-scale coconut decomposing machines, and the region must import it from other regions. As a result, the utilization of coconut fiber in fiber and cocopeat is still minimal. Plus, when bringing in from outside, the logistics cost of the coconut husk decomposing machine is still high. This research aims to conduct a techno-economic analysis of a small-scale coconut husk decomposer from the machine designed and made. The research method was using the experimental method. The results showed that the equipment can produce cocofiber and cocopeat with 600 kg of husk per day for 6 hours of use. The results of economic calculations based on the IRR value, the net B/C ratio, and the payback period show that this machine is feasible to be developed on a small scale for Farmer groups. Technologically, this machine is simple and relatively easy to operate. Further research hopes this machine will prove its durability over long, heavy work periods.

Abstract

Long beans are one type of vegetable hortcultural plant that is popular throughout the world which is widely used as food or daily consumption, produced to be used as seeds and used as medicines in the world of health. This study aims to determine the effect of applying various fertilizers on the growth and production of string bean plants. This research was conducted in Lembang Village, Banggae Timur District, Majene Regency, Sulawesi Barat Province. The treatment in this study was designed with a simple Group Randomized Design with 4 treatments and 4 repetitions, namely P0 = No Fertilizer (control), P1 = Leachate 5 ml, P2 = MOL 5 ml, P3 = NPK Fertilizer 5 ml. Leachate and MOL as liquid organic fertilizers dissolved in water and applied per week after planting. NPK fertilizer as an inorganic fertilizer that is thawed with water and applied per week after planting. The results showed that the treatment of various fertilizers (P0, P1, P2, and P3) did not have a real effect on the growth and production of string bean tama, especially on the number of fruits. while the application of leachate water fertilizer dose of 5 ml (P1) gave higher results on the height and number of leaves of long bean plants compared to without fertilizer (P0) and the application of MOL 5 ml (P2) and NPK dose 5 ml (P3). The effect of applying NPK 5 ml (P3) fertilizer on the growth of long bean plants only appears in the variable number of leaves.

Abstract

Cement mining by exploiting Maros karst, South Sulawesi, produces waste in the form of gypsum, which still has the potential to be used in bioremediation as a planting medium for plant commodities. The research aims to determine the growth of chili plants on former cement mining media treated with mycorrhiza and biohumic—the biohumate used from an extract of cocoa pod husk. The research was structured using an experimental method with 5 treatments, namely primary media in the form of soil + manure as a control, gypsum 30 g/polybag, gypsum 60 g/polybag, gypsum 30 g/polybag+mycorrhiza, gypsum 60 g/polybag+mycorrhiza. The treatment was then divided into 2, with biohumic and without biohumic. The research showed that all observed parameters had higher values in the biohumic treatment than without biohumic. Treatment with 30 g gypsum/polybag + mycorrhiza can improve the physical properties of the soil by changing the percentage composition of soil fractions. It can also increase P2O2 and K2O levels and provide the best growth for chili plants. It is possible to utilize waste from cement mines to produce horticultural commodities by bioremediation with mycorrhiza and biohumate.

Abstract

Red chili (Capsicum annuum) is a leading horticultural commodity that is perishable and seasonal, so it must be sold immediately after being harvested. To extend its lifespan and durability, processing is required which of course requires additional costs. Marketing processed products in the era of globalization of trade includes various challenges which should be interpreted as opportunities to be able to compete in international markets. KWT LARASATI took the initiative to process large red chilies in order to increase the added value of the harvest and also extend its shelf life. From this process, KWT LARASATI then produces high-value product diversification in the form of processed chili sauce under the Sambal Simbok brand. One variant of the chili sauce produced is tuna chili sauce. So far, KWT LARASATI has carried out marketing techniques in the form of utilizing existing social media, namely WhatsApp, Facebook and Instagram. However, KWT Larasati still faces a number of obstacles in marketing its Sambal Simbok tuna chili variant to the public. Based on this background, it is necessary to have a strategy in marketing the Sambal Simbok product, a tuna chili variant so that it can produce alternative strategies that suit the processed chili products in KW LARASATI business diversification, as well as using QSPM analysis to determine strategic priorities that are in accordance with internal and external aspects. KWT. The results of this analysis are eight alternative strategies which are then ranked to determine the prioritized strategy.
