Published: January 2021

Abstract
Social capital is the main resource in developing strategies to overcome natural disasters as well as to mobilize community participation in preserving environmental based-local wisdom. Social capital is the ability of individual and communities to represent their own resources and transgenerational solidarity driven by high trust and shared values to achieve goals through established social relations. This paper is intended to explore why the social capital are able to build communities’ behaviour that minimize the occurrence of environmental degradation. The study was conducted in Wonosobo Regency, Central Java Province. Historically, the region was the first place for bottled water production in Indonesia. However, the source of the spring water of the region remain sustainable up until now. The study’s results show that the strength of social capital in local communities contributes to the effectiveness of building collective action for environmental conservation. The strength of social capital also accelerates capacity building and transformation process of local institutions in order to reduce environmental degradation. More specifically, social capital entities that play an important role are participation in a network, trust, reciprocity, solidarity, togetherness and mutual cooperation.

Abstract
This study aimed to determine nutrient status, mycorrhiza population, and yields of maize-soybean strip intercropping in sandy soil environments of North Lombok, Indonesia. The experiment designed with Randomized Block Design with three blocks and five treatments, i.e., P1 (2 rows of maize: 2 rows of soybean), P2 (3 rows of maize: 2 rows of soybean), P3 (3 rows of maize : 3 rows of soybean), P4 (4 rows of maize: 2 rows of soybean), P5 (4 rows of maize : 3 rows of soybean). The results show that an increase of one more row from 3 to 4 rows significantly decreases the weight of maize cobs (3.5-folds), pods (2.3-folds), and 1000 seeds (1-folds). One row of maize plant density, which was beginning three rows to 4 rows, causes a decrease in the weight of dry root biomass and shoot of maize and soybean plants. The root weight and dried shoots of maize fell to 3.5 and 4.5 times, and the weight of dried roots of soybeans fell to 1.41 times at the age of 92 days after observing the 4:3 ratio of maize and soybean plants.

Abstract
This study aimed to know the potential use of mung bean (Vigna radiata L. Wilzeck) as a cover crop and its effect on soil organic carbon and maize yield were studied. Six cover crop treatments; 250,000, 375,000 and 500,000 plants/ha combined with desiccation times at 28 and 35 days after sowing (DAS) and one control treatment (without cover crop), were tested in a semi-arid area of North Lombok. Maize at a density of 98,000 plants/ha was planted two weeks following the desiccation time. The treatments were arranged in a Randomized Block Design with three replications. The results revealed that the higher cover crop population density with later desiccation time, produced higher above ground biomass, being the highest at 8.3 Mg/ha and the lowest at 2.6 Mg/ha. The highest cover crop biomass improved soil organic carbon by 60%, nitrogen, phosphorous and potash concentrations in plant tissue by 54%, 54% and 63%, respectively, compared to the one in the control treatment. Maize yield also increased by 24% at the highest cover crop density desiccated at 35 DAS. The use of mung bean as a cover crop sounds promising and further studies are needed to explore more of its potential benefits.

Abstract
Rainfed lowland rice is the second largest rice growing areas in Indonesia. One of the most vulnerable agro-ecosystems to the climate change is the rainfed lowland because of the erratic, unpredictable rainfall and most of them have very limited access on water resources. The aim of this study was to investigate the greenhouse gas (GHG) emission, production, soil fertility and economic efficiency of integrated crop-livestock management system (ICLS) and farmer practice (FP). The study was conducted at the farmer’s field in Jaken, Pati, Central Java, Indonesia during wet season. The result showed that ICLS in rainfed lowland areas could (1) reduced greenhouse gas (GHG) emission from paddy rice by implementing integrated crop (paddy rice) management technique (ICM), (2) avoided CH4 release from manure of livestock using anaerobic digester to the atmosphere and used the CH4 production for energy purpose, (3) improved the soil fertility by giving additional composted farmyard manure to the soil, and (4) enhanced the economic benefit for farmers. ICLS approach is one of the options where adaptation and mitigation technology could be conducted in a synergistic way.

Authors: Khoiruddin M L , Utami A W , Irham I 
Published: January 2021

Abstract
ENSO (El Niño Southern Oscillation) climate anomaly has become more frequent and stronger because of global warming and climate change. ENSO arguably plays a critical role in tropical countries such as Indonesia, primarily due to its intrinsic linkage with agricultural production and prices. This study examines one such relationship between ENSO and the price volatility of Crude Palm Oil (CPO), one of the most produced and consumed vegetable oils in the world. By applying time-series data from 2006 to 2018 and Ocean Nino Index (ONI) which serves as a proxy for the ENSO variable, this research used Autoregressive Conditional Heteroscedasticity (ARCH) methods to find out the CPO price volatility and Vector Error Correction Model (VECM) to investigate the impact of ENSO on the CPO price volatility. The results showed that the price volatility of CPO in Indonesia is low and will be persistent in the long term. ENSO affects the volatility of CPO prices in the long run, but there is no effect in the short run. The result is important for the stakeholders and government in preventing the risk and uncertainty condition of CPO price fluctuation caused by the climate anomaly.

Abstract
Palm oil smallholder who managed more than 40% of palm oil area in Indonesia are expected to comply with the mandatory regulation of sustainable palm oil (ISPO). However, basically there are two types of smallholder whose condition need to be considered to develop the most suitable certification scheme. This paper aimed to (1) see the difference in socio-economic characteristics between independent and managed smallholders, (2) identify the behavioral factors of independent and managed smallholder as well as (3) analyze the compliance of smallholder towards ISPO indicators. The data of smallholders of Padang Lawas Regency, North Sumatera were collected in terms of socio-economic characteristics, behavioral factors, and compliance towards ISPO. The results of the study showed that socio-economic characteristics of independent and managed smallholder are significantly different in term of ages, education, family member, experiences, farm sizes, and on farm income. Besides, there is a wide gap between the behavioral factors of managed and independent smallholder towards ISPO indicators. It is implied by the attitude, social norm, ability to perform, and intention to comply with the sustainable scheme. However, in average, smallholders considered to have bad compliance towards the indicators of ISPO.

Abstract
COVID-19 encouraged the efforts to find its prevention and treatment. Indonesia possesses myriads of plant diversity, many of which have anti-microbial effects. Singawalang plant (Petiveria aleaceae) has been used as an alternative treatment for tuberculosis, malaria, and other diseases in Indonesia and other countries. Active ingredients of Singalawang are flavonoids and various types of amino acids found in the leaves and roots. The purpose of this study was to investigate the role of dolomite, zeolite, and NPK fertilizers in increasing nutrient absorption and Singawalang growth in entisol soils. P. alleaceae were planted in polybags using entisol soils medium by using a Completely Randomized Design (CRD). Zeolite, dolomite (2.5 tons/ha), and NPK Fertilizer (15:15:15) at a dose of 0; 1.5; 3; 4.5 g/plant were applied. The results showed that the amendment application had a significant effect on the number of leaves but did not significantly affect other growth parameters and nutrient absorption of NPK. In general, zeolites can increase the growth and absorption of nutrients higher than dolomite.

AbstractThis study aimed to predict the egg production of quails supplemented with a combination of betaine and silica+. Three hundred and fifty laying quails were divided into two dietary treatments and seven replicates of 25 quails. The treatments consisted of control (T0), and supplementation with digestibility enhancer mixture consisted of 0.12% betaine and 200 ppm silica+ (T1). Egg production data were collected for three periods of 28 days, and they were subjected to T-test. The data were plotted to obtain the egg production curve. A logistic regression model was employed to identify the trend of the egg production pattern. The T1 groups produced more eggs than T0 groups (P<0.05), which attributed to the higher egg production during period II and III (P<0.01). The egg production curves indicated that production rose sharply soon after the beginning of lay. The T1 groups had a higher peak production than T0 (76.43% vs 69.20%). Furthermore, production rate was 0.17 and 0.18 and prediction accuracy was 97% and 98% for T0 and T1, respectively. Thus, the logistic model proved to be employed to analyse the biological impact of egg production in quails with a high prediction accuracy.

Abstract
Lettuce (Lactuca sativa L.) is a vegetable whose commercial value is quite good and the demand for lettuce has increased, including from hydroponic results. The use of rockwool planting media in hydroponics is often not available when needed and is expensive. Therefore it is necessary to study of using local planting media, such as: coconut fiber and rice husk charcoal as a replacement of rockwool planting media and whether the increased concentration of nutrients given to the planting media affects the rate of plant growth and yield of lettuce. The purpose of this research to study are interaction between planting media and nutrient concentrations (AB Mix) on the growth and development rate of plants, as well as the yield of lettuce hydroponically with the NFT system. The research was arranged in factorial with two factors using a Split Plot Design. The the main plot is AB Mix nutritional concentration (K) consisting of 3 levels (600 ppm, 900 ppm and 1200 ppm), while the subplot is a planting media (M) consisting of 3 treatment, namely: Rockwool, Coconut Fiber, and Rice Husk Charcoal. The results showed that the combination treatment of rice husk charcoal planting media and AB Mix concentration of 1200 ppm (M3K3) produced the best growth and increased the fresh weight of lettuce plants by 447,54% compared to the combination treatment of rockwool media and AB mix concentration of 600 ppm (M1K1). Rice Husk Charcoal planting media increases the growth rate of plant length and leaf area respectively by 26% and 81,54% compared to rockwool planting media. AB Mix concentration of 1200 ppm gives the best response and increases the growth rate of plant length and lettuce leaf area respectively by 367,5% and 165% compared to the concentration of 600 ppm.

Abstract
Fire accidents these days are becoming an alarming issue resulting in numerous deaths globally. In spite of having a robust system to put off the fire from spreading quickly, very less progress has been made in technology to rescue trapped people with only human efforts still taking place to rescue. While carrying out these manual rescue operations one major factor which hinders is the smoke, produced as a result of the fire, which greatly reduces the visibility thus making this task very risky. To address this issue, we have devised a negative ion generator, the anion (negative ion) generator is capable of removing a smoke and dirt particles from the air thereby increasing the visibility. This article presents a prototype where a fire extinguishing robot equipped with negative ion generator and can be deployed at an incident site.
