Background: Stunting is a nutrition problem that can slow down the growth. With prevalence at 32.5%, Landak Regency in West Kalimantan has been designated as a stunting hotspot. The lack of a maximum penalty for the stunting case in Landak Regency is not based on factors causing the stunting itself, because there is no identifiable factor causing the stunting in certain area due to narrow roads and sharp curves. Objectives: The objective of this study was to identify causes and distribution of the stunting case in Landak Regency. Methods: A total of 330 households in Meranti, Sebangki, and Senakin were included in this cross-sectional study because they were at a risk of the stunting. Toddlers, mothers, health care, and environmental factors were among the found variables. The researchers employed a basic random sampling strategy for the sampling and used the secondary health center data to find out whether or not toddlers were stunted. Researchers in this study collected data on the independent variables by observing and interviewing participants. Using the chi-square test, the data was analyzed. Results: The results showed that determinants of the stunting in Landak Regency were the history of early breastfeeding initiation (p-value=0.032), exclusive breastfeeding (p-value=0.042), frequency of exclusive breastfeeding (p-value=0.040), the continued breastfeeding (p-value=0.024), complementary feeding (p-value=0.042), immunization history (p-value=0.007), infectious disease history (p-value=0.000), maternal height (p-value=0.046), delivery assistance (p-value=0.000), access to health services (p-value=0.004), the role of health workers (p-value=0.002), and family latrine ownership (p-value=0.000). Conclusions: Several factors were found to be associated with incidence of the stunting among toddlers in Landak Regency.

Embung Leuwi Padjadjaran II merupakan bangunan penampung air yang berlokasi di Desa Cileles, Jatinangor. Pembangunan embung ini bertujuan untuk menghindari terjadinya banjir saat musim hujan tiba. Namun, keadaan embung mempunyai kenampakan fisik yang buruk. Bagian atas badan air embung dipenuhi dengan tumpukkan tanah. Hal tersebut mengindikasikan adanya erosi yang terjadi di daerah tangkapan air embung. Tujuan dari penelitian ini adalah untuk memetakan sebaran lokasi erosi dan konservasi tanah dan air di Daerah Tangkapan Air Embung Leuwi Padjadjaran II. Erosi yang terjadi pada setiap satuan unit lahan mempunyai tingkat bahaya erosi yang berbeda-beda yang dihitung menggunakan persamaan USLE berdasarkan faktor-faktor erosi. Faktor-faktor erosi tersebut antara lain: faktor erosivitas hujan (R), faktor erodibilitas tanah (K), faktor panjang kemiringan lahan (LS), faktor pengelolaan tanaman (C) dan faktor pengelolaan konservasi (P). Tingkat bahaya erosi paling dominan di daerah tangkapan air embung adalah tingkat bahaya erosi sangat tinggi (>480 ton/ha/th). Sedangkan, tingkat bahaya terendah dimiliki oleh tingkat bahaya erosi rendah (15-60 ton/ha/th). Konservasi tanah dan air menjadi solusi yang direkomendasikan dalam menanggulangi masalah erosi yang terjadi daerah tangkapan air embung. Penerapan koservasi tanah dan air ditentukan berdasarkan Pedoman Pemilihan Teknologi Konservasi Tanah secara Mekanis dan Vegetatif berdasarkan Tingkat Kemiringan Lahan, Erodibilitas Tanah dan Kedalaman Solum (P3HTA).

Corn waste, tithonia and cattle manure are three materials that have different characteristics. These charactersitics differences if used together in the composting process will complement each other and potentially produce good compost. This research was conducted to find out how the composting process characteristics by utilizing the three raw materials with different characteristics in a composting process. The composting process was carried out using a berkeley method which was stacked with a layered bioreactor. The decomposition process that occurs involving decompisted bacteria, so the composting process runs aerobically. Aerobic composting corn waste with the addition of tithonia and cattle manure finished in about 4-5 weeks to become a mature compost. The quality of the compost produced is quite good because the content contained in compost fulfills most of the quality standards regulated in SNI 7763: 2018. The addition of tithonia and cattle manure has a positive impact in the process of composting corn plants in terms of duration and good compost.

Among the two pyrolysis methods, the two-stage type gives better results than the single-stage in converting mixed municipal solid waste (MMSW) into synthetic oil (O-Synthec) and gaseous products (G-Synthec). However, the double energy supply for the heating process in the first and second reactors needs to be considered in terms of efficiency. Therefore to complete the research of two-stage pyrolysis, this study improvised a two-stage co-pyrolysis process supported by a Long Fixed-Bed Catalytic Insert (LFCi) attached to the inner wall of the reactor. In the test, 500 g of MMSW with 8 components was fed into a reactor with LFCi containing a dolomite natural catalyst. The co-pyrolysis process was carried out at a temperature variation of 400–550 °C, and the best results obtained were used as a reference for variations in reaction time from 120 to 210 min. Based on the physical and chemical properties, the co-pyrolysis O-synthec and G-synthec products were subjected to Gas Chromatography Mass Spectrometry (GCMS) analysis and American Society for Testing and Material (ASTM) standard to physical properties test. The results were compared with those of one-stage pyrolysis, direct catalytic and without catalyst. Based on the results, the presence of LFCi in the reactor had a significant effect in increasing the mass yield of O-Synthec at 550 °C with a residence time of 150 min. An increase of 20,14% and decrease 16.77% of O-Synthec and G-Synthec respectively were achieved compared to the uncatalyzed, although the presence of 15.5% peak area oxygenated fractions and 3.0% peak area acid needs to be considered as it impacts the calorific value. The dominant aromatic compound indicates that O-Synthec has similarities with conventional gasoline fuel. Meanwhile, the non-condensable gas (G-Synthec) produced contains a concentration of hydrocarbon compounds in the distribution of C1–C12, which is dominant with tripropylaluminum, formic acid and butenes. The high content of formic acid and tripropylaluminum compounds in G-Synthec must be considered because they are very corrosive and hazardous to the environment.
