Abstract

Usman A, Wibowo A, Ramadhan MR, Purnomo RH. 2020. Palm oil mill effluent potency as a fuel for portable stove with internet of things-based monitori. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Palm oil mill effluent processing in general is still carried out conventionally. However, this process requires a large area. In addition, conventional waste ponds can produce methane (CH4) and carbon dioxide (CO2) which cause the greenhouse effect. If not treated properly, the palm oil mill effluent can give bad impacts to the environment. This paper contains the potential of palm oil liquid waste into biogas energy which is applied to portable stoves with Internet of Things (IoT)-based monitoring. The potential of palm oil mill effluent is studied based on in-depth and extensive literatures. The processing of palm oil mill effluent into biogas energy can be done with anaerobic digester technology which is added with one or two different substrates. To increase the percentage of methane gas, pressure swing absorption technology can be used. The sensor used for monitoring is adjusted to the observed parameters. The MQ2 sensor is used as gas leak detector, a load cell and the HX711 module are used  as a load detector for gas cylinder, and LM35 is used as a temperature detector. Palm oil mill liquid waste has a potential to become biogas energy which can be applied in portable stoves with a Internet of Things (IoT)-based monitoring.

Fatmawaty D, Purnaweni H, Luqman Y.  2020.  The community participation in tackling cases of pollution and/or environmental damage. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang  20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).The Law Number 32 of 2009 concerning Environmental Protection and Management in article 70 states the rights and opportunities for the community to play an active role in environmental protection and management. The roles that can be played by the community include: a) social supervision, b) providing suggestions, opinions, suggestions, objections, complaints; and/ or c) submission of information and/ or reports. However, the community participation is still not running optimally. It can be seen from the increasing number of pollution and or environmental damage cases from year to year. This review aims to find out how the implementation of community participation in handling cases of environmental pollution and / or damage as an effort to protect the environment and what obstacles are faced in this implementation. The scope of the article reviewed includes the role of the community and the role of the government in handling cases of pollution and or environmental damage. Cases of pollution and environmental damage are handled by the Government through supervision and law enforcement, and by involving community participation through social monitoring, filing complaints and submitting information and / or reports. The results of the review show that community participation is still not effective in overcoming cases of pollution or environmental damage.

Nugraha FA, Maryono M.  2020.  Drought community capacity assessment in Windurojo village, Pekalongan regency. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Windurojo Village is an area in Pekalongan Regency which is quite often hit by drought. In terms of morphogenesis, Windurojo Village is located in folds of structural hills with soil types dominated by grumusol. This makes during the dry season, the wells in the village dry up faster than other areas. A village scale disaster capacity study needs to be carried out in these areas so that the results of the study are more specific and have a more direct impact on the community. So that the purpose of this study is to determine the level of capacity of village scale units in Windurojo Village, Kesesi District, Pekalongan Regency. The process of collecting data is observation and interviews which are processed quantitatively. The analysis technique used is scoring. The results of the village scale capacity analysis show that there is only one hamlet with a low capacity, namely Dusun Serang, while Dusun Leles has a high level of capacity, Dusun Karangmoncol and Dusun Kuthawangi have a moderate level of capacity. From the findings, we think that the drought in Serang Hamlet is a socio-economic drought.

Sakir IM, Sriati S, Saptawan A, Juniah R.  2020.  History of floating rice nursery as ogan ethnic local wisdom managing wetlands. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang  20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).This study aims to examine the history of floating rice nurseries and the local wisdom of the Ogan ethnic in Pemulutan in managing the wetland swamp environment. The research method used is phenomenology for describing in detail the phenomena of the agricultural system carried out by the Pemulutan community. The results showed that the history of floating rice nurseries carried out by the Ogan ethnic group is estimated to have existed since the traditionalist generation. The traditionalist generation is a generation that is simple, patriotic and wise in managing the environment. The simplicity is shown by the Ogan ethnic group in Pemulutan in managing lowland swamp farming, using local resources such as wild plants from swamp grass (berondong) and freshwater algae (reamon). Berondong and Reamon are the names of local people for floating rice nurseries. The Ogan ethnic group uses natural resources around agricultural land as a form of local wisdom to adapt to their environment. Local wisdom in managing lowland swamps is Indonesia's cultural wealth that must be preserved. The Pemulutan community preserves the swamp farming system using floating techniques. This agricultural model has been applied from generation to generation as a legacy of wetland swamp farming. Wetland in west Pemulutan is spreading over 11 villages, namely; The bund or shallow backland area is around 1,279 hectares or 33 per cent, the middle backland area is 1,909 hectares or 49 per cent, the remaining 18 per cent or 736 hectares are deep backlands. The bund and middle backland are potential lands for agricultural cultivation, while deep backland is using for fisheries and livestock.

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).This study aimed to examine the effect of synbiotic levels (a combination of L.casei and glucomannan from porang tuber extract) and the duration of administration on the growth of the digestive tract and the performance of Tegal ducks. A total of 180 male Tegal ducks, 2 days old with an average body weight of 42,33±2,54 were used in this study. The treatment rations were prepared with a metabolic energy of 3000 kcal/kg and crude protein 18%. The research was arranged in a factorial completely randomized design, with 2 factors. The first factor was the synbiotic level (1 and 2%), while the second factor was the duration of synbiotic administration (2,3 and 4 weeks). The collected data were analyzed for variance and continued with the Duncan multiple region test. The results showed that there was an interaction between the synbiotic level and the duration of synbiotic administration on the length of the duodenum, jejenum and ileum as well as the final body weight of Tegal ducks. The conclusion was that 2% of synbiotics for 4 weeks increased intestinal growth and body weight of Tegal ducks.

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx.  Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Nowadays the expansion of agricultural areas is starting to spread to suboptimal land, with the main problems that stand out are poor water, nutrients and organic matter. This situation causes improvement in plant growth to become a major problem in suboptimal land. Therefore, a sustainable suboptimal land agricultural practice is needed through the application of organic, inorganic, and mycorrhizal bio-fertilizers. This study aims to determine the growth response of five varieties of maize treated with organic fertilization packages (15 tons/ha of cow fertilizer), inorganic (Urea 300 kg/ha and Phonska 200 kg/ha) and mycorrhizal biofertilizers (1.5 tons/ha) in suboptimal land of North Lombok. The research was conducted in the Village of West Pemenang, Pemenang District, North Lombok Regency. A field experimental was designed with Randomized Block Design with three replications and five treatments of maize varieties, namely V1 (P8IS variety), V2 (P8DPP variety), V3 (Gumarang variety), V4 (Lemuru variety), and V5 (Sukmaraga variety). Parameters observed were plant height and number of leaves at 14, 28, and 42 days after seeding (das), wet and dry weight of roots and shoot at 42 das, number of mycorrhizal spores and percentage of root colonization at 42 das. Observation data were analyzed using analysis of variance (ANOVA) and Tukey's HSD (Honestly Significant Difference) means-tested at a 5% level of significance. The results showed that the Sukmaraga (V5) variety showed the best growth response in the application of organic, inorganic and mycorrhizal biofertilizers in suboptimal land of North Lombok.

Irmanida B, Prastya ME.  2020.  The potency of indonesian spices and traditional medicine plants as for the sources of fungtional foods ingredients. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).As a public knowledge pertanining healthy lifestyle increases, the need for food that has health benefits also increases. This food is popular as a functional food, which is not only contains nutrients, but also has a physiological benefits to prevent or cure diseases. One of the sources of functional food ingredients in Indonesia are spices and medicinal plants which are known containing various types of phytochemical compounds. Numerous reports showed a health benefits of phytochemical compounds derived from spices and medicinal plants such as ginger (Zingiber officinale), turmeric (Curcuma domestica), cardamom (Amomum cardamomum), legetan warak (Adenostemma lavenia), the god’s crown (Phaleria macrocarpa), and lambo guava (Psidium guajava). The phytochemical compounds from those plants are recognized to prevent or cure various diseases including high blood pressure, cancer, diabetes, flu, coughs, sore throat, etc. Functional food products based on spices and medicinal from these 6 plants are usually in the form of jamu, instant healthy drinks, tea, juices, sweets, syrups, etc. Functional food based on Indonesian spices and medicinal plants has the potential to be developed because of its high demand, adequate production and a lot of research that has been conducted. Although the Indonesian government has made the regulations on special nutritious food, these regulations are considered insufficient. Therefore, the government needs to make a specific and comprehensive regulations on functional food in Indonesia, specifically those based on spices and medicinal plants.
