The physical growth that occurs in schoolage children makes this period one of the most important phases in the human life cycle. Within this period, puberty is indicated by growth spurts that increase both stature (BH) and bodyweight (BW). The focus of this research was to evaluate the age-related body size variation in Sasak children living at different altitudes on the island of Lombok, Indonesia: low, medium, and high. Our results showed that children living at low altitude were taller and heavier than children of the same age living at medium and high altitudes. Up until the onset of puberty, the children at medium altitude have similar stature and weight to those residing at high altitude, but they are shorter and lighter thereafter. There were significant differences in the height and weight of girls in different altitude locations, but no significant difference for boys. The effect of SES on child growth can be comparison between Sasak and other populations in Indonesia. In general, the Sasak children are shorter and lighter than children of the same age in urban populations, and relatively similar in size to the children in rural populations. Indicators of socioeconomic status such as family income and parental education were shown to be more influential factors in the differentiation of physical growth between populations than the altitude factor
Coral reefs are unique ecosystems and only occur in the tropics area. One of the coral reef distribution in Indonesia is Lombok Island. The coral reefs in Lombok Island under degradation conditions caused by natural and human activities. The purpose of this study was to provide an overview of the benthic profile and substrate of coral reefs in the Labuhan Pandan waters, Eastern Lombok. Observations were conducted in March 2019 at 5 stations using the Underwater Photo Transect (UPT) method. The results showed that in general benthic coral reefs were dominated by Acropora Branching (35.40%) then followed by Soft Coral (20.89%), DCA (14.08%), Coral Foliose (11.07%), Rubble (7.36%) and Halimeda (2.77%). The highest percentage of Acropora Branching were found at KND_01 station (63.33%) followed by PTG_01 (49.13%), PTG_02 (31.18%), BDR_01 (21.73%), and PTG_03 (11.00%). The highest DCA percentage was found at BDR_01 station (29.27%) while Soft Coral was found dominant at PTG_02 (47.67%). Halimeda was only found in PTG_02 (1.87%) and PTG_03 (12.00%). Differences in the composition of benthic and substrate may be caused by differences in water conditions at each station.
Pulau Lombok memiliki kawasan hutan mangrove seluas 3.305 ha, 1.643 ha (49,7%) masih dalam kondisi baik dan sisanya 1.662 ha (50,3 %) dalam kondisi rusak. Penelitian keanekaragaman moluska diekosisitem mangrove pantai Cemare Lombok Barat dilakukan pada bulan April s/d Juli 2019 dengan tujuan untuk mengetahui keanekaragaman moluska pada ekosistem mangrove yang mengalami rehabilitasi di Pulau Lombok. Pengambilan sampel menggunakan metode transek kuadran dengan ukuran plot 1 m x 1 m. Jumlah induvidu moluska yang didapatkan yaitu 719 individu yang terdiri atas 24 spesies dari kelas Gastropoda dan 3 spesies dari kelas Bivalvia. Nilai kelimpahan, indeks keanekaragaman, indeks keseragaman dan dominasi tertinggi berturut-turut yaitu 29 (ind/m2); 2,55; 0,77; 0,12.
