Abstract

Lahan gambut merupakan komponen ketahanan lingkungan yang diupayakan untuk menjamin keamanan publik dan munculnya bahaya lingkungan yang disebabkan secara alami oleh alam maupun disengaja oleh perbuatan manusia. Lahan gambut di Desa Teluk Empening telah mengalami konversi menjadi lahan usahatani seperti lahan sawit, karet dan jahe, sedangkan lahan sekunder yang ada pada daerah penelitian sebelumnya pernah mengalami kebakaran pada tahun 2017. Penelitian ini dilakukan dengan mengidentifikasi keanekaragaman jenis pada lahan gambut dengan melakukan pengukuran biodiversitas lahan dengan analisis vegetasi. Kemudian menganalisis pengaruh konversi lahan gambut dengan pengukuran sifat fisik tanah, pengukuran Tinggi Muka Air tanah, pengukuran dimensi saluran dan pengujian kualitas air. Perubahan dinamika tutupan lahan yang dipengaruhi oleh kondisi sosial ekonomi masyarakat, data diperoleh dengan menggunakan observasi, wawancara dan kuesioner sebanyak 30 sampel. Hasil analisis menunjukkan lahan jahe, karet dan sawit memiliki nilai indeks keanekaragaman (H’) ±0 dikategorikan biodiversitas rendah. Lahan sekunder memiliki nilai indeks keanekaragaman (H’) 2,001 masuk kategori biodiversitas sedang. Konversi lahan gambut mempengaruhi sifat fisik tanah gambut seperti parameter porositas, permeabilitas, kadar serat dan kadar air. Konversi lahan gambut menjadi lahan karet memengaruhi penurunan muka air tanah yaitu setinggi 68 cm. Pengaruh konversi terhadap kualitas air pada lahan, ditandai dengan parameter pH berkisar 3,3 - 4,6, TSS berkisar 6-440 mg/l dan DO berkisar 0,89-3,4 mg/l yang tidak sesuai dengan baku mutu yang ditetapkan yaitu Kelas 2 PP No.82 Tahun 2001. Konversi lahan gambut semakin meningkat tiap tahun dan mempengaruhi kondisi sosial ekonomi masyarakat dengan fungsi sosial penyerapan tenaga kerja serta fungsi ekonomi pendapatan dari hasil produksi usahatani. Lahan gambut memberikan keunggulan dan kapasitas bagi kawasan lokal untuk kekuatan alam seperti lingkungan, ekonomi dan sosial yang dapat dilakukan sambil tetap menjaga daya tahan lingkungan. AbstractPeatlands are a component of environmental resilience that strives to ensure the safety and security of environmental hazards caused naturally or intentionally by human actions. Peatland in Teluk Empening Village has undergone conversion to agricultural land such as oil palm, rubber and ginger, while the secondary land in the previous study area experienced fires in 2017. This research was conducted by identifying the diversity of species on peatland by measuring biodiversity land with vegetation analysis. Then analyze the effect of peat land conversion with physical measurements of soil, measurement of groundwater level, measurement of channel dimensions and testing of water quality. Changes in land cover dynamics obtained from socio-economic conditions, data obtained using observations, interviews and questionnaires as many as 30 samples. The analysis showed that ginger, rubber and oil palm land had a diversity index value (H ') ± 0 which was categorized as low biodiversity. Secondary land has a diversity index value (H ') of 2,001 in the medium biodiversity category. Peat land conversion affects the physical properties of peat soil such as parameters of porosity, permeability, fiber content and air content. The conversion of peatlands to rubber lands has an effect on the decrease in the water table, which is 68 cm long. The effect of conversion on water quality in land, fear with pH parameters ranging from 3.3 to 4.6, TSS ranging from 6-440 mg / l and DO ranging from 0.89-3.4 mg / l which are not in accordance with the specified quality standards namely Class 2 PP No. 82 Year 2001. Conversion of peatlands is increasing every year and affects the socio-economic conditions of the community with the social function of absorption of labor and the economic function of income from agricultural production. Peatlands provide advantages and capacities for local areas for natural forces such as environment, economy and social that can be done while maintaining environmental resilience.

Dry conditions can cause peatlands to burn easily. It is necessary to make efforts to wet the peatlands to protect peatlands from dry conditions. During the dry season, it is difficult to obtain surface water. A reliable source of water is groundwater. The extraction of groundwater is good and controlled, it needs to be done with simple knowledge and technology. This is necessary so that the wetting of the peatlands can be done in a participatory manner. To achieve the goal, an effort was made to socialize the method of making boreholes that can be done by the community in a participatory manner. This socialization is one of the community service (PKM) carried out by the implementation team, with funding from the Ministry of Research, Technology, and Higher Education in 2019. This PKM activity was carried out in Wajok Hilir Village, Siantan District, Mempawah Regency, West Kalimantan. This activity begins with conducting an in-depth interview to multiply the problems at the location of the activity. The socialization was carried out by lecturing methods and field practice involving the local community. The community was very enthusiastic about participating in the socialization. The impact of these activities is to improve the health of the environment and the community as well as to serve as a source of raw water for daily needs. This activity also has an impact on increasing the knowledge and capacity of the local community in particular, and it is hoped that it can disseminate information to the wider community. Keywords: peatlands; drought, boreholes; participatory; wajok hilir.

Abstract

Data availability of on a river discharge is the key to waterworks planning. Unfortunately, not all rivers have long and complete historical data records to support the planning. Therefore, a hydrological model capable of predicting long-term river discharge is needed. There are many hydrologic models that have been developed, ranging from the simplest ones by using empirical black-box model, to complex ones with physical white-box model. This study used ANN application due to its data requirement that is applicable to be met in study area, Sekayam River, a part of Kapuas Subwatershed, namely Kembayan Watershed. Although the available data is relatively minimal, which is only rainfall and evaporation data, the ANN application can predict river discharge that is close to the measurement in the field, with a mean square error (MSE) of 0.25. The results show that ANN application was able to predict river discharge reasonably with climate and rainfall data as the input. Deviation may occur due the broad scope of the research area, Kembayan Watershed, a Kapuas Subwatershed which amounted to 2,290 km2.

Abstract

          Formalin sebagai bahan pengawet pada ikan umum digunakan untuk memperpanjang masa simpan, namun penggunaan formalin berdampak buruk bagi kesehatan. Daun Afrika memiliki senyawa saponin yang mampu mereduksi kadar formalin. Penelitian ini bertujuan mengetahui efektivitas perendaman ekstrak daun Afrika (Vernonia amygdalina Del) untuk mereduksi kandungan formalin pada fillet ikan Nila (Oreochromis niloticus). Penelitian ini menggunakan Rancangan Acak Lengkap dengan satu faktor yaitu konsentrasi ekstrak daun Afrika (0%, 1%, 2%, 3%, 4%, dan 5%), dengan 3 kali ulangan. Identifikasi saponin pada ekstrak daun Afrika dianalisis secara kualitatif menggunakan metode Forth. Fillet ikan Nila direndam selam 30 menit ke dalam ekstrak daun Afrika pada masing-masing konsentrasi. Penurunan kadar residu formalin diuji secara kuantitatif menggunakan metode pereaksi Schiff. Hasil menunjukkan bahwa ekstrak daun Afrika pada konsentrasi 1%, 2%, 3%, 4%, 5% teridentifikasi senyawa saponin. Perendaman fillet ikan Nila berformalin ke dalam ekstrak daun Afrika efektif dan berpengaruh positif terhadap reduksi kadar formalin.  Konsentrasi ekstrak daun Afrika 5% memiliki kadar formalin terendah sebesar 0,73 mg/Kg masih di bawah ambang batas International Program on Chemical Safety sebesar 1,5–14 mg/Kg, demikian juga kadar abu sebesar 1,04% sesuai dengan mutu ikan segar Standar Nasional Indonesia 01-2354.1-2006 yaitu kurang dari 2%.                                                                                Formalin used as preservative fish is generally carried out to extend shelf life. However, the use of formalin has an adverse effect on health. Saponin compounds contained in African leaves are able to reduce formalin content. This study aims to determine the effectiveness of immersing African leaf (Vernonia amygdalina Del) extract to reduce the formalin content in tilapia (Oreochromis niloticus) fillets. The experimental design used a completely randomized design with one factor, the concentration of African leaf extract (0%, 1%, 2%, 3%, 4%, and 5%), with three-time replications. Saponin identification in African leaf extract was analyzed qualitatively using the Forth method. Tilapia fillets were immersed for 30 minutes into the African leaf extract at each concentration. The reduction in formalin content was tested quantitatively by Schiff reagent method. The results showed that the African leaf extract at a concentration of 1%, 2%, 3%, 4%, 5% identified saponin compounds. Immersion of formalin tilapia fillets into African leaf extract was effective and significantly affects reducing formalin content. The concentration of 5% African leaf extract had the lowest formalin content of 0,73 mg/Kg below the threshold of International Program on Chemical Safety 1,5-14 mg/Kg, as well as ash content of 1,04% according to the quality of fresh fish Indonesian National Standard 01-2354.1-2006 is less than 2%.
