Abstract

This research aims to see the effect of temperature and extraction time on water content, yield and methoxyl content of coconut fiber pectin. This research was carried out experimentally factoril in Design Random Complete, which consists two treatment that is temperature extraction and extraction time with three repetitions. The results of this research show that treatment temperature extraction very influence yield pectin, rate water and methoxyl pectin while the extraction time affects the water content of the pectin. At a temperature of 70 O C and long extraction 60 minutes obtained the highest average yield of pectin, namely 4.31%, while the average the lowest pectin yield was obtained from treatment with an extraction temperature of 90 ° C and an extraction time of 90 minute. Average rate methoxyl highest obtained from treatment temperature 70 O C and long extraction 30 minute, whereas average percent rate methoxyl Lowest obtained from treatment with an extraction temperature of 90 O C and an extraction time of 90 minutes, namely 8.03% and 7.61% respectively. From the results obtained, it was concluded that the pectin obtained was classified as deep pectin group with high methoxyl content, namely >7%. Average percent of pectin content The lowest was 90 O C and the extraction time was 90 minutes, namely 10.19%, while the highest obtained from treatment with an extraction temperature of 70 O C and an extraction time of 30 minutes. From the results of the analysis this water content means that the water content of the coconut fiber pectin obtained is deep study this has fulfil condition for water content dry pectin that is 10-14%.

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.

Abstract

One effort to reduce the use of inorganic fertilizer is by using organic fertilizer using manure or rice husk charcoal. The research used chicken manure with 3 levels: A0 = 0 kg/plot (0 ton/ha), A1 = 3.75 kg/plot (10 tons/ha), A2 = 7.5 kg/plot (20 tons/ha), A3 = 11.25 kg/plot (30 tons/ha). The second factor, husk charcoal with 3 levels: S0 = 0 kg/plot (0 ton/ha), S1 = 1.9 kg/plot (5 tons/ha), S2 = 3.8 kg/plot (10 tons/ha), S3 = 5.7 kg/plot (15 tons/ha). The results showed that treatment with a dose of chicken manure at 7.5 kg/plot significantly increased leaf length, tuber wet weight per plant, tuber wet weight per plot, tuber dry weight per plant, tuber dry weight per plot, root volume, soil pH. , soil CEC, soil C-organic content, but had no significant effect on the number of bulbs and Si uptake of shallot plants. The activated charcoal dose treatment had no significant effect on leaf length, number of tubers, wet weight of tubers per plant, wet weight of tubers per plot, dry weight of tubers per plant, dry weight of tubers per plot and root volume. The interaction between the dose of chicken manure and husk charcoal had no significant effect on all parameters observed, and had no significant effect on the availability of silica in paddy fields.

Abstract

Coconut (Cocos nucifera L.) known by many as the "tree of life is a leading agricultural commodity in North Sulawesi. Coconut is one of the most significant palm crops for both commercial and subsistence use worldwide. Airmadidi District has the potential for plantation land, especially coconut, which is indicated by the area of ??coconut plantation land in Airmadidi in 2021 of 3,373.13 Ha. This research aims to produce spatial mapping of coconut plantation in Airmadidi District using visual interpretation techniques; and to determine the area of ??coconut plantations in Airmadidi District. Visual interpretation method using on screen classification of satelite imagery SPOT 2022 obtained from SAS Planet.  Images were digitized with a geographic information system using ArcGIS 10.8.2 software. The results of the visual interpretation show a map of the distribution of coconut plantations spread across all villages in Airmadidi District, North Minahasa Regency. The total area of coconut plantations in Airmadidi District is 3 023 Ha. Tanggari village has the largest spread of coconut plantations, namely 870,460 Ha, while Sarongsong Satu village has the smallest area, only 2.24 Ha. There was a decrease in the area of coconut plantation during the period of three year which was 305,51 Ha.  The decline in the area of coconut plantations in North Sulawesi, especially in Airmadidi District, is thought to be caused by the conversion of coconut plantation land into residential or industrial areas.

Abstract

In order to accelerate the development of the tourism sector, the Indonesian government has designated five tourist destinations in Indonesia as super priority tourist destinations, one of which is East Likupang of North Minahasa Regency in North Sulawesi Province. Paal Beach is one of the main tourist attractions in East Likupang. Even though the beach is very beautiful and the access to it is very good, the number of visits is still far below it's carrying capacity. This research aims to identify appropriate development strategies for the Paal Beach tourist destination to attract more visitors. The analytical tool used is SWOT analysis. The research results show that various external factors are very supportive for the development of Paal Beach.  However, the beach still has various weaknesses that could make it unattractive for some people to visit.   The main identified weaknesses are related to the lack of adequate infrastuctures and supporting facilities So, the main strategy should be to prioritize improving these infrastuctures and supporting facilities. If infrastuctures and supporting facilities are improved, then this area has great potential to be able to take advantage of the existing external factors identified as opportunities, especially with the designation of East Likupang as one of the super priority tourist destinations in Indonesia.

Abstract

This research aims to design and test a soybean epidermis peeling machine that is cost-effective, efficient, and suitable for small-scale farmers in remote areas. The research process involved designing, manufacturing, and technical testing of the TETA-II model soybean peeler. The data collected during the research was analyzed descriptively. The results showed that the TETA-II model soybean peeler has an average working capacity of 43 kg/hr at an engine speed of 2450-2550 (rpm) with a soybean soaking period of 6 hours. The highest yield from the peeler was achieved at a soybean soaking time of 8 hours (95.955%) and 6 hours (94.02%) at rpm 2450-2550. In future studies about the machine, to improve its efficiency, the scrubber roll system should be adjusted to regulate the stability of the fall of the soybeans being peeled, and the inner walls must be coated with plastic.
