Genjer merupakan tanaman yang tumbuh liar di area persawahan, rawa, atau sungai yang keberadaannya sering dianggap sebagai gulma. Tanaman genjer memiliki banyak manfaat, diantaranya sebagai bahan penyerap logam berat dalam tanah dan sebagai obat yang memiliki banyak kandungan gizi. Penelitian ini bertujuan untuk mengetahui variasi karakter morfologi dan karakter agronomi untuk mengetahui hubungan kekerabatan tanaman genjer antar daerah di Kabupaten Pangandaran. Penelitian dilaksanakan di Kabupaten Pangandaran pada Mei sampai Oktober 2015. Metode yang digunakan adalah metode eksplorasi purposive sampling pada 77 aksesi genjer yang diambil dari Kabupaten Pangandaran. Hasil penelitian menunjukkan terdapat keragaman fenotipik yang luas pada karakter morfologi ujung daun, warna batang, tekstur daun, warna daun, panjang lekukan bawah daun, warna kelopak bunga dan warna bunga. Karakter agronomi yang mempunyai keragaman yang luas ialah tinggi tanaman, jumlah batang per rumpun, panjang daun, lebar daun, jumlah daun, jumlah bunga dan diameter batang. Tanaman genjer di Kabupaten Pangandaran memiliki kekerabatan yang jauh dengan rentang jarak Euclidian 0,48 sampai 10,17. Aksesi yang memiliki hubungan kekerabatan paling jauh yaitu Ciakar (001) dengan jarak Euclidian 10,17, sedangkan yang memiliki hubungan kekerabatan paling dekat yaitu Cikalong (003) dan Cikalong (004) dengan jarak Euclidian 0,48. Genjer or Yellow velvetleaf is a plant that grows wild in lowland area, swamp or river which existence is considered as a weed. Genjer has a lot of benefits, such as material absorbent for heavy metals in the soil and medicine that has a lot of nutrition. This study aimed to determine the variety of morphological and agronomic characters of Genjer in Pangandaran Regency and to determine the genetic relationship of genjer between regions in Pangandaran. The research was conducted in the Pangandaran Regency on May to October 2015. The method used purposive sampling exploration method in 77 accession genjer collected from Pangandaran Regency. The results showed there were extensively phenotypic variation in tip of leaf, stem color, leaf texture, leaf color, length curve of bottom leaf, petal color and flower color. While agronomic characters for plant height, stem amount, leaf length, leaf width, leaf amount, flower amount and diameter of the stem had wide variation. Relationship between genjer in Pangandaran Regency had Euclidean distance with a range of 0.48 to 10.17. The accession which had the farthest distance was Ciakar (001) with Euclidean distance of 10.17, while those with the closest relationship were Cikalong (003) and Cikalong (004) with Euclidean distance of 0.48.

Heavy metals (HMs) toxicity represents a global problem depending on the soil environment’s geochemical forms. Biochar addition safely reduces HMs mobile forms, thus, reducing their toxicity to plants. While several studies have shown that biochar could significantly stabilize HMs in contaminated soils, the study of the relationship of soil properties to potential mechanisms still needs further clarification; hence the importance of assessing a naturally contaminated soil amended, in this case with Paulownia biochar (PB) and Bamboo biochar (BB) to fractionate Pb, Cd, Zn, and Cu using short sequential fractionation plans. The relationship of soil pH and organic matter and its effect on the redistribution of these metals were estimated. The results indicated that the acid-soluble metals decreased while the fraction bound to organic matter increased compared to untreated pots. The increase in the organic matter metal-bound was mostly at the expense of the decrease in the acid extractable and Fe/Mn bound ones. The highest application of PB increased the organically bound fraction of Pb, Cd, Zn, and Cu (62, 61, 34, and 61%, respectively), while the BB increased them (61, 49, 42, and 22%, respectively) over the control. Meanwhile, Fe/Mn oxides bound represents the large portion associated with zinc and copper. Concerning soil organic matter (SOM) and soil pH, as potential tools to reduce the risk of the target metals, a significant positive correlation was observed with acid-soluble extractable metal, while a negative correlation was obtained with organic matter-bound metal. The principal component analysis (PCA) shows that the total variance represents 89.7% for the TCPL-extractable and HMs forms and their relation to pH and SOM, which confirms the positive effect of the pH and SOM under PB and BB treatments on reducing the risk of the studied metals. The mobility and bioavailability of these metals and their geochemical forms widely varied according to pH, soil organic matter, biochar types, and application rates. As an environmentally friendly and economical material, biochar emphasizes its importance as a tool that makes the soil more suitable for safe cultivation in the short term and its long-term sustainability. This study proves that it reduces the mobility of HMs, their environmental risks and contributes to food safety. It also confirms that performing more controlled experiments, such as a pot, is a disciplined and effective way to assess the suitability of different types of biochar as soil modifications to restore HMs contaminated soil via controlling the mobilization of these minerals.

AbstrakLatar belakang : Kejadian stunting merupakan salah satu  masalah gizi pada anak yang memiliki prevalensi tinggi di Indonesia. Cut off point  kejadian stunting tidak boleh lebih dari 20%, sedangkan jumlah kejadian stunting di Surabaya sebanyak 22,8%. Salah satu penyebab tingginya kejadian stunting yaitu penyakit infeksi. Penelitian ini bertujuan untuk mengetahui hubungan riwayat sakit dengan kejadian stunting pada balita. Metode : Penelitian ini merupakan penelitian analitik observasional dengan menggunakan rancang penelitian case control. Jumlah sampel yang diteliti sebanyak 40 balita dengan usai 24-36 bulan di wilayah kerja Puskesmas Simomulyo Surabaya. Sampel penelitian balita stunting merupakan kelompok kasus dan balita non-stunting merupakan kelompok kontrol. Pengambilan data untuk kelompok kasus menggunakan purposive sampling dan pada kelompok kasus menggunakan matching sampling dengan menyesuaikan usia bayi dan jenis kelamin pada kelompok kasus. Pengumpulan data mengguanakan instrumen kuisioner. Uji statistik menggunakan chi square Hasil : Hasil penelitian ini didapatkan balita stunting memiliki riwayat sakit sebanyak 90%, sedangkan pada balita non-stunting sebanyak 45%. Uji statistik menggunakan mengenai hubungan riwayat sakit dengan kejadain stunting pada balita dengan uji Chi square didapatkan hasil yang signifikan yaitu p=0,002 (<0,05) dan OR 4,889. Kesimpulan : Balita stunting memiliki riwayat sakit lebih sering daripada balita non-stunting.AbstractBackground: . The incidence of stunting is one of the nutritional problems in children who have a high prevalence in Indonesia. The cut off point for stunting events should not be more than 20%, while the number of stunting events in Surabaya is 22.8%. One of the causes of the high incidence of stunting is an infectious disease. This study aimed to determine the relationship of a history of illnes with the incidence of stunting in infants. Method: This research was an observational analytic study using a case control research design. The number of samples were 40 toddlers (20 toodlers with stunting and 20 toodlers with non-stunting) aged 24-36 months in the working area of the Simomulyo Primary Health Care in Surabaya. The stunting toddlers belonged to a case group and non-stunting toddlers belonged to a control group. Data collection of case group had used purposive sampling and that control group used matching sampling by adjusting the baby's age and gender in the case group. Data was obtained by questionnaire instrument.Data was analysis by Chi square Results: The persentage of stunting toddlers who had a history of illness was 90%, while the non-stunting toddlers had a history of illness was 45%. There was relationship between the history of infectious diseases and the occurrence of stunting in toodler p=0,022 (<0,05) and OR=4,338. Conclusion: Stunting toddlers have a history of pain more often than non-stunting toddlers
