Abstract

One type of the Amorphophallus genus that has high economic value is Amorphophallus Muelleri, which is known as the local name Porang. Porang tubers are used to obtain glucomannan which is widely used in the drug industry. Currently, many porang tubers come from the forest and have not been widely cultivated. In Lombok island of, several species of Amorphophallus spp are found. Therefore, a preliminary study of the habitat information of Amorphophallus spp. in East Lombok is urgently needed, especially in the Kokok Tojang sub-watershed. This study aims to determine the habitat of Amorphophallus spp based on actual and potential existence data. The method used in this study is a purposive sampling method, namely by looking for actual and potential locations where Amorphophallus spp.  In this study, two types of Amorphophallus were found, namely A. paeoniifollius and A muelleri. Habitat characteristics of Amorphophallus spp described by soil and microclimate parameters. Soil parameters include soil moisture (15-70% and an average of 28.5%); Soil temperature (24-29 oC), soil fertility (ideal) soil texture (clay clay, sandy loam, and dusty clay), conductivity (0.07 – 0.52 mS/cm). Microclimate parameters measured include temperature (19.4 – 30.3oC), humidity (64.4% – 81.4%), light intensity (60.3 – 22526.8 lux).

Abstract

Komak bean (Lablab purpureus (L.) Sweet) belongs to the family Fabaceae and subfamily Papilionidae. Komam bean is cultivated by people for consumption as an additional food source. Informationabout the active compound content of komak bean is needed as a reference in the utilization of komak. This research aims to determine the active compounds contained in komak seed (Lablab purpureus (L.) Sweet). This study used GC-MS analysis to determine the active components of the komak bean seed. Based on research result, komak Beak Bongkor bean contain 13 active components, they were toluenea, methyl octanoat, adacene 12, isododecane, caprylic acid, retardex, 1-undecene 7-methyl-, methyl caprate, capric acid, benzoic acid 4-ethyl-, palmitic aldehyde, methyl laurate dan lauric acid.

Abstract. Several problems related to the use of chemical fertilizers are fertilizer prices that continue to increase, in certain situations there is a shortage of fertilizers and continuous use can reduce the population of soil microorganisms. The purpose of this community service activity is to provide counseling and training on the manufacture of liquid organic fertilizer from plant waste using EM4 activator to the youth of Ubung Village, Jonggat District. The method of activity is lectures and practice of making liquid fertilizer, harvesting fertilizer products and packaging. The activity has been carried out in accordance with the plans and stages that have been set, and liquid fertilizer has been produced which is packaged in plastic bottles. The physical characteristics of the liquid fertilizer produced after 20 days of the fermentation process showed results that met the criteria as a good liquid organic fertilizer, namely temperature 28oC, pH 4, brownish yellow color and smelled of tape. Liquid fertilizer has been distributed to target residents and used as plant fertilizer. Through this activity, the youth of Ubung Village who are participants have succeeded in making liquid organic fertilizer based on plant waste and have applied it as fertilizer to their plants.

Abstract

Mangrove ecosystem is a unique ecosystem with a mix of marine and terrestrial environment. Mangrove forests provide food and nutrients for other organisms such as fish,crustaceans, and algae. Red algae play an important role in maintaining the balance of ecosystems and food chains. This study aims to determine the types, morphological characteristics and key identification, the relationship of red algae types and substrate types to the ecosystem of mangrove forest in Dusun Ekas. This research is explorative descriptive by using purposive sampling method at 5 stations. Based on the results of the red algae study obtained as many as 14 species are: Bostrychia sp., B. radicans, B. tenella, Chondria sp., Laurencia sp., Polysiphonia sp., Murrayella sp., C. Leprieurii, C. Monostica, Gelidium sp ., Gelidium crinale, Catenella caespitosa, Catenella nippae and Catenella sp.Characteristics of the talus were found to have a cylindrical talus and some like leaves (blade). Red algae (Rhodophyta) found more in the station that dominated by Soneratia alba species.

Abstract

Komak (generally assumed and known as Lablab purpureus (L.) Sweet) is one of the important food commodities in Fabaceae family, especially for people on Lombok Island, West Nusa Tenggara. Komak bean is also one of the common plants which is widely grown on Lombok Island in general. The objects of this research are to explore the various uses on some morphological variants of komak plant in Central Lombok Regency as one of komak production area on Lombok Island, including its potency of development strategies. This descriptive exploratory research was conducted in Central Lombok Regency as one of the important areas for komak population, supported by interviews, participatory observation and documentation. Snowball sampling method was applied in informant selection. Data were analyzed based on the calculation of Reported Use (RU) and Index of Cultural Significance (ICS). As the results, there are about 10 (ten) utilizations of komak plant reported by the community: as food, yard plants, land boundaries, economic plants, natural fertilizers, ecological functions (soil cover/erosion prevention), animal feed, seasonal indicators, ritual, and socio-cultural functions. Dissemination of information about processing technology and utilization of komak plant are still needed in order to support the optimalization of the management and utilization of this commodity as one of potential legumes that has a strategic role in realizing national food security.

Abstract

Komak bean is one type of local beans that are quite widely cultivated. Komak beans have various important ingredients so that it can become alternative food stuffs and produce a variety of food products. North Lombok Regency is one of the komak bean cultivation center in West Nusa Tenggara. Information regarding the use and condition of the komak bean’s habitat in North Lombok Regency is not much known. Based on this, research is needed to be done related to the use and characteristics of komak bean habitats. This study aims to determine the diversity of komak bean, variety of utilization, habitat characteristics, and local wisdom in komak bean conservation. The methods used are field observations, interviews and measurements of environmental factors. Respondents were selected by purposive sampling and snowball sampling with semi-structured interview. In this study, the types of komak beans was found consisted of Lablab purpureus ssp. purpureus, Lablab purpureus var. lignosus, Lablab purpureus var. typicus, and Phaseolus lunatus. The variety of uses of komak beans in North Lombok Regency are as food ingredients, animal feed, a component of gifts in traditions, land barriers, and shade. Cultural Significance Index (CSI) value show P. lunatus as the most important type with value of 32 or almost used in all varieties of utilization. Komak beans grow at soil temperature ranges from 26℃-33℃, soil moisture 20-80%, 25℃-36℃ air temperature, air moisture 34-92%, and soil pH is range 4-8. The dominant texture of the soil are sandy clay and silty clay. Various traditional ways that are applied by the public to preserve komak seeds, namely mixing with rough salt, betel chalk and coconut oil, turmeric powder, and crushed seeds of Schleichera oleosa.
