This essay is a summary of a training activity of water conservation and application of biopori holes at two villages in Bengkulu Province, i.e. Pering Baru village surrounded by palm cultivation, Suro Lembak dominated by vegetable farming. Both villages were experienced with shortage of water during dry season and plenty of water during rainy season. So people from both villages were eager to be trained on water conservation and implementation of biopori hole. Water conservation in palm plantation and vegetable farming were done by making ditches perpendicular with the slope of lands in order to collect runoff water and lead to infiltration. Moreover,  biopori holes could be constructed around their homes in order to increase water infiltration, and also to be used as organic waste digester for producing composts. This biopori holes protected from malaria diseases due to no more stagnant water.

Water conservation forests significantly contribute to the stability of mountain agricultural ecosystems in Hani Terrace. In this study, we analyzed the relationship between the stable isotopic composition of soil water and precipitation to determine the mechanisms of soil water movement in the small watershed of Quanfuzhuang. We observed significant seasonal variations in soil water sources: antecedent precipitation was the dominant supply during the dry season, and current precipitation dominated during the rainy season. The recharge ratio of precipitation to soil water in the grassland was significantly higher than that in the arbor land and shrubland. The influence of water infiltration, old and new soil water mixing, and soil evaporation on the soil water stable isotopes gradually decreased from the surface (0–20 cm) to the deep (60–80 cm) soil. We observed significant seasonal variability in average soil water δ18O in the upper 0–60 cm and lower variability at 60–100 cm. The average soil water δ18O was generally higher in the dry season than in the rainy season. The mixing of old and new water is a continuous and cumulative process that is impacted by soil structure, soil texture, and precipitation events. We therefore identified a significant time delay in soil water supply with increasing soil depth. Moreover, the piston flow of soil water co-occurred with preferential flow, and the latter was the dominant supply during the rainy season.

<p>Clean water crisis that occurred in Bandung is caused by land conversion in North Bandung area which is a recharge area into commercial buildings. This increases runoff rate from 40% to 70% that can lead can lead to flooding and reduced groundwater availability. Therefore, it is necessary to save water by implementing water conservation. Considering those problems, this study aims to apply the concept of water conservation in X Apartment building that is located in the North Bandung Region by referring to Mayor Regulation of Bandung in 2016. Water conservation efforts that will be applied are wastewater reuse into water recycle, rainwater harvesting, infiltration well construction and placing water meters. The application of water conservation concept considers two conditions, namely in rainy season and dry season. Total need for clean water can be saved by 45,8% in dry season, while in rainy season clean water can be saved by 31,74%.</p>

The reduction in green open space causes its reduction in the surface that can absorb water into the ground in residential areas. An increase in the amount of wasted rainwater that is wasted due to the reduced rate of water infiltration into the soil will cause flooding in the rainy season and drought in the dry season. A solution is needed to absorb water into the soil. Trisakti University in collaboration with Cisalak Village and the Indonesian Water Partnership held the training and counseling on the application of Biopore Infiltration Holes to residents of RW 12. This Community Service activity supports the program target of making 100,000 LRBs in Depok City. The method used was counseling conducted online and offline. After the counseling activity, the team made 80 LRBs equipped with booklets and X-banners containing procedures for making LRBs.

The study aims to assess spatial and temporal water quality variations in the upper reaches of the Vietnamese Mekong Delta. Thirty-one water monitoring samples of the two main rivers (Tien and Hau Rivers) and six canals flowing through An Giang Province were collected in the dry season (March) and the rainy season (September) from 2009 to 2019. Seven physicochemical parameters were analyzed including temperature, pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), total suspended solids (TSS), orthophosphate (P-PO43-), and coliforms. Water quality index (WQI), cluster analysis (CA), and discriminant analysis (DA) were applied to evaluate water quality, spatial and temporal variations, and seasonal discriminant water variables. WQI values (15–71) indicated surface water quality was very bad to medium in which the water quality in larger and in smaller rivers in the dry season was less polluted than that in the rainy season due to erosion and runoff water containing waste materials in the wet season. CA grouped the water quality in the dry and rainy seasons into four clusters mainly due to BOD and coliforms in the dry season; TSS and coliforms in the rainy season. Discriminant analysis revealed that DO, TSS, coliforms, temperature and BOD significantly contributed to seasonal variations in water quality. Therefore, water quality monitoring in the surveyed area could only focus on DO, TSS, coliforms, temperature and BOD to reduce monitoring cost.

Increasing and developing infrastructure in urban areas has resulted in decreased water infiltration quality into the ground. The increasing of settlement needs and raising its price has resulted in many water catchment areas changing their function unconsciously in urban areas. This condition was ultimately triggering the loss of opportunities for rainwater to into the ground. At present, when the rainy season arrives, almost all major cities in Indonesia experience flooding. The torrential rains that lasted just 1 hour were enough to cause relatively high inundation, which varied from 30 cm to over 1m. This study aims to analyze the intensity of rainfall and its impact on the potential for flooding in urban areas and how to overcome it by utilizing rooter system technology. The results showed that the 4-way rooter system technology's influence was considerable in reducing the water level. An experimental area of 100 m2 treated with a rooter system of 16 pipes with a water level of 40 cm can infiltrate stagnant water into the soil within 120 minutes. Meanwhile, in the same area without rooter technology, it takes 400 minutes to absorb water into the soil until the stagnant water is completely gone. This proves that the rooter system technology plays a significant role in accelerating water absorption into the ground, reducing the risk of flooding.

<p class="AbstractEnglish"><strong>Abstract:</strong> As a natural resource that is vital in supporting human life, the evaluation of the availability of water resources is an urgency in determining and projecting the condition of water surplus or deficit in a Wilayah. There are various methods in evaluating the availability of water resources in an area, one method that has a high level of significance is the Thornthwaite Mather water balance method. Water balance analysis was carried out in 3 Wilayahs in Java Island which have monsoonal rain types, including Bandung, Begawan Solo watershed, and Pasuruan. The results of the evaluation of the availability of water resources in Bandung show a surplus condition of water in the rainy season period and deficit in the dry season period. Meanwhile, the water balance analysis in Solo shows deficit conditions in all areas covered by the Bengawan Solo watershed. Water balance analysis in Pasuruan Regency shows the same pattern as the Bandung area, where there is a surplus condition in the rainy season and deficits in the dry season period. While the results of the projection of the availability of water resources show varying results in the three Wilayahs, where there is generally an increase in the number of Wilayahs experiencing water deficits. Based on these conditions, water conservation efforts need to be formulated, both by the community and the local government.</p><p class="KeywordsEngish"><strong>Abstrak:</strong> Sebagai sumber daya alam yang sangat vital dalam menunjang kehidupan manusia, evaluasi ketersediaan sumber daya air merupakan sebuah urgensi dalam menentukan serta memproyeksikan kondisi surplus atau defisit air di suatu wilayah.

Hasil evaluasi ketersediaan sumber daya air di Bandung menunjukkan kondisi surplus air pada periode musim penghujan dan defisit pada periode musim kemarau. Sementara itu, analisis neraca air di Solo menunjukkan kondisi defisit pada seluruh area yang tercakup dalam DAS Bengawan Solo. Analisis neraca air di Kabupaten Pasuruan menunjukkan pola yang sama dengan wilayah Bandung, dimana terjadi kondisi surplus pada periode musim penghujan dan defisit pada periode musim kemarau. Sedangkan hasil proyeksi ketersediaan sumber daya air menunjukkan hasil yang bervariasi pada ketiga wilayah, dimana secara umum terjadi peningkatan jumlah wilayah yang mengalami defisit air. Berpijak pada kondisi tersebut, upaya-upaya konservasi air perlu segera dirumuskan, baik oleh masyarakat maupun pemerintah daerah setempat.</p>

The increasing of malaria cases in recent years at Kecamatan Kalibawang has been suspected correspond with the conversion of farming land-use which initiated in 1993. Four years after the natural vegetation in this area were changed become cocoa and coffee commercial farming estates, the number of malaria cases in 1997 rose more than six times, and in 2000 it reached 6085. This study were aimed to observe whether there were any differences in density and diversity of Anopheles as malaria vector between the cocoa and mix farming during dry and rainy seasons. The results of the study are useful for considering the appropriate methods, times and places for mosquito vector controlling. The study activities comprised of collecting Anopheles as well as identifying the species to determine the density and diversity of the malaria vector. Both activities were held four weeks in dry season and four weeks in rainy season. The mea-surement of physical factors such as temperature, humidity and rainfall were also conducted to support the study results. Four dusuns which meet the criteria and had the highest malaria cases were selected as study location. Descriptively, the results shows that the number of collected Anopheles in cocoa farming were higher compared with those in mix horticultural farming; and the number of Anopheles species identifi ed in cocoa farming were also more varied than those in the mix horticultural farming.Key words: bionomik vektor malaria, anopheles,

Abstract Purpose Life cycle assessment studies on smallholder farms in tropical regions generally use data that is collected at one moment in time, which could hamper assessment of the exact situation. We assessed seasonal differences in greenhouse gas emissions (GHGEs) from Indonesian dairy farms by means of longitudinal observations and evaluated the implications of number of farm visits on the variance of the estimated GHGE per kg milk (GHGEI) for a single farm, and the population mean. Methods An LCA study was done on 32 smallholder dairy farms in the Lembang district area, West Java, Indonesia. Farm visits (FVs) were performed every 2 months throughout 1 year: FV1–FV3 (rainy season) and FV4–FV6 (dry season). GHGEs were assessed for all processes up to the farm-gate, including upstream processes (production and transportation of feed, fertiliser, fuel and electricity) and on-farm processes (keeping animals, manure management and forage cultivation). We compared means of GHGE per unit of fat-and-protein-corrected milk (FPCM) produced in the rainy and the dry season. We evaluated the implication of number of farm visits on the variance of the estimated GHGEI, and on the variance of GHGE from different processes. Results and discussion GHGEI was higher in the rainy (1.32 kg CO2-eq kg−1 FPCM) than in the dry (0.91 kg CO2-eq kg−1 FPCM) season (P < 0.05). The between farm variance was 0.025 kg CO2-eq kg−1 FPCM in both seasons. The within farm variance in the estimate for the single farm mean decreased from 0.69 (1 visit) to 0.027 (26 visits) kg CO2-eq kg−1 FPCM (rainy season), and from 0.32 to 0.012 kg CO2-eq kg−1 FPCM (dry season). The within farm variance in the estimate for the population mean was 0.02 (rainy) and 0.01 (dry) kg CO2-eq kg−1 FPCM (1 visit), and decreased with an increase in farm visits. Forage cultivation was the main source of between farm variance, enteric fermentation the main source of within farm variance. Conclusions The estimated GHGEI was significantly higher in the rainy than in the dry season. The main contribution to variability in GHGEI is due to variation between observations from visits to the same farm. This source of variability can be reduced by increasing the number of visits per farm. Estimates for variation within and between farms enable a more informed decision about the data collection procedure.
