Coconut water can increase the growth and yield of plants because itcontains plant growth regulator (PGR): auxin, cytokinin and gibberellin, vitamin, and mineral.The research was carried out to know: 1) the effect of coconut water concentrations on the growth and yield of mungbean and 2) concentration of coconut water that provide the best growth and yield of mungbean. The experiment was conducted during three months, from September until November 2017, located in Samarinda.The experiment was arranged in Completely Randomized Design (CRD) wasa single factor experiment, concentration of coconut water, consisted of four treatments: 0; 20; 40; and 60% of coconut water and each treatment was replicated six times. The data were analyzed by analysis of variance (anova) and continued by Least Significant Difference (LSD) test at significantlevel of 5%.Variables that observed were plant height, number of branches, number of pods, number of seeds, number of unfilled pods, weight of filled pods, andweight of seedsper plant.The result showed that the effect of coconut water concentrations was highly significant on plant height at 4, 6 weeks and at harvest time, number of pods, number of seeds, weight of filled pods, and weight of seeds per plant,howeveritwas significantly different on plant height at 2 weeks and number of branches, and it was no significantly different on number of unfilled pods. The best growth and yield of mungbean obtained by concentration 40% of coconut water.

Teknik penambangan terbuka memiliki banyak dampak negatif yaitu berubahnya kondisi suatu lingkungan dengan penurunan produktivitas tanah, pemadatan tanah, erosi dan sedimentasi, serta terjadinya gerakan tanah atau longsoran. Penelitian ini bertujuan untuk mengetahui harian (sensitivitas tanah terhadap erosi) dan mengidentifikasi jenis erosi di area pasca tambang batubara. Penelitian ini dilaksanakan selama 6 bulan efektif, pada areal bekas tambang batubara pada land revegetasi tahun 2017. Metode yang digunakan dalam penelitian ini adalah metode survey dan metode purposive sampling, Menentukan titik pengamatan sebanyak 10 titik pengamatan. Kemudian observasi dan pencatatan data di lapangan dan analisis laboratorium. Pendugaan erodibilitas tanah dilakukan dengan cara pengambilan contoh tanah, penentuan struktur tanah, permeabilitas tanah pada saat dilapangan, serta penentuan tekstur tanah dan bahan organik untuk dianalisis di laboratorium. Identifikasi erosi dengan mengambil dokumentasi jenis erosi yang mengacu pada referensi dan fakta yang ditemukan pada saat di lapangan. Untuk mengetahui nilai erodibilitas (kepekaan tanah terhadap erosi) menggunakan nomograph (erosibilitas tanah). Hasil penelitian menunjukkan bahwa nilai erodibilitas pada land revegetasi tahun 2017 di PT Mahakam Sumber Jaya berkisar antara 0,17-0,26 masuk ke kelas rendah-sedang, hasil identifikasi erosi ditemukan ada 5 jenis erosi yaitu erosi parit, erosi percikan, erosi lembaran, erosi nyata, dan longsor.

Penelitian ini   bertujuan untuk mengetahui pertumbuhan dan hasil tanaman jagung (Zea mays L.) terhadap pemberian beberapa jenis kandungan pupuk majemuk pada lahan pasca tambang batubara dan mengetahui jenis kandungan pupuk majemuk terbaik untuk pertumbuhan dan hasil tanaman jagung (Zea mays L.) pada lahan pasca tambang batubara. Penelitian dilaksanakan di lahan pasca tambang batubara Desa Bangun Rejo, Kecamatan Tenggarong Seberang, Kabupaten Kutai Kartanegara, Kalimantan Timur. Penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan satu faktor yaitu pemberian beberapa pupuk majemuk (P), terdiri dari 5taraf dan 5 ulangan yaitu p0= Tanpa Pupuk; p1= 500 kg.ha-1NPK 20:10:10 setara 4,2 kg.petak-1;p2= 500 kg.ha-1 NPK 17:9:11 setara 4,2 kg.petak-1; p3= 500 kg.ha-116:16:16 setara 4,2 kg.petak-1 dan p4 = 500 kg.ha-1 setara 4,2 kg.petak-115:20:13 setara 4,2 kg.petak-1. Hasil penelitian menunjukkan bahwa pemberian beberapa komposisi pupuk majemuk berbeda tidak nyata terhadap semua parameter yang diamati yaitu tinggi tanaman, diameter batang, jumlah daun, panjang tongkol, diameter tongkol, jumlah baris biji, jumlah biji dalam baris, berat biji per tongkol, berat biji per 100 butir, dan potensi hasil.

Stunting in children under five is a public health problem in Indonesia, especially in lowland areas related to food consumption patterns. This study aims to determine the relationship between food consumption patterns and the incidence of toddler stunting in lowland areas in the Province of South Kalimantan, Indonesia. This type of research is quantitative descriptive, and the sample study amounted to 166 toddlers 12-59 months. The instrument used was a threaded form of the expected food pattern score (DDP) and a 24-hour food recall to determine the diversity of food consumption for toddlers. To determine the relationship between food consumption patterns and stunting, Chi-Square analysis (α = 0.05) was used. The results showed that the average actual energy of under five was quite diverse, with a DDP score of 76.4. The average energy consumed by toddlers at 1296.4 kcal/cap/day. The highest food groups consumed by toddlers are grains at 740.3 kcal/cap/day, and the lowest oily seeds fruit food group at 7.8 kcal/cap/day. Based on the analysis of Chi-Square shows the results of 21.715 and p-value = 0.000 (α = 0.05), then α > p-value indicates a link between food consumption patterns in toddlers with the incidence of stunting in toddlers in lowlands.

Abstract. The efforts to increase rice production at East Borneo apart from the improvement of cultivation systems also could be done by using superior variety. Hybridization of rice plants has been done between the female local variety Pandan Ungu and the male local variety Roti. The research toward F2 progeny to find out the segregation patterns of inheritance of the characters number of tillers, plant height, stem leaves color, and palea-lemma color has been done at the paddy field at Desa Sidomulyo, Kecamatan Anggana, Kabupaten Kutai Kartanegara since October 2016 until March 2017. The F2 identification method that was used is single plant selection methods, based on Standard Evaluation Systems (SES) for Rice. Suitability test between observed value and expected value used Chi-square test, and to see the characters segregation pattern ratio used Mendelian genetics analysis. The inheritance character of stem leaves color was managed by two pairs of genes followed segregation ratio 9:6:1 with the action epistatic genes with cumulative effect, the inheritance of palea-lemma character was managed by two pairs of genes followed Mendelian ratio 13:3 with the action epistatic dominant-recessive, while the characters plant height and number of tillers was managed by polygenes so the inheritance patterns was not following Mendelian ratio.
